Merge 9.2 (#657) * upstream: attemp FIDO key signing without PIN and use the error code returned to fall back only if necessary. Avoids PIN prompts for FIDO tokens that don't require them; part of GHPR#302 OpenBSD-Commit-ID: 4f752aaf9f2e7c28bcaaf3d4f8fc290131bd038e * Install Cygwin packages based on OS not config. * initial list of allowed signers * upstream: whitespace OpenBSD-Commit-ID: d297e4387935d4aef091c5e9432578c2e513f538 * upstream: whitespace OpenBSD-Commit-ID: a5d015efbfd228dc598ffdef612d2da3a579e5d8 * Add cygwin-release test target. This also moves the cygwin package install from the workflow file to setup_ci.sh so that we can install different sets of Cygwin packages for different test configs. * Add Windows 2022 test targets. * Add libcrypt-devel to cygwin-release deps. Based on feedback from vinschen at redhat.com. * cross-sign allowed_signers with PGP key Provides continuity of trust from legacy PGP release key to the SSHSIG signing keys that we will use henceforth for git signing. * additional keys * upstream: whitespace OpenBSD-Commit-ID: c2bcbf93610d3d62ed206cdf9bf9ff98c6aaf232 * Move sftp from valgrind-2 to 3 to rebalance. * upstream: sk-usbhid: fix key_lookup() on tokens with built-in UV explicitly test whether the token performs built-in UV (e.g. biometric tokens) and enable UV in that case. From Pedro Martelletto via GHPR#388 OpenBSD-Commit-ID: 007eb7e387d27cf3029ab06b88224e03eca62ccd * Remove arc4random_uniform from arc4random.c This was previously moved into its own file (matching OpenBSD) which prematurely committed in commit 73541f2. * Move OPENBSD ORIGINAL marker. Putting this after the copyright statement (which doesn't change) instead of before the version identifier (which does) prevents merge conflicts when resyncing changes. * Resync arc4random with OpenBSD. This brings us up to current, including djm's random-reseeding change, as prompted by logan at cyberstorm.mu in bz#3467. It brings the platform-specific hooks from LibreSSL Portable, simplified to match our use case. ok djm@. * Remove DEF_WEAK, it's already in defines.h. * openbsd-compat/bsd-asprintf: add <stdio.h> include for vsnprintf Fixes the following build failure with Clang 15 on musl: ``` bsd-asprintf.c:51:8: error: call to undeclared library function 'vsnprintf' with type 'int (char *, unsigned long, const char *, struct __va_list_tag *)'; ISO C99 and laterclang -O2 -pipe -fdiagnostics-color=always -frecord-gcc-switches -pipe -Wunknown-warning-option -Qunused-arguments -Wall -Wpointer-arith -Wuninitialized -Wsign-compare -Wformat-security -Wsizeof-pointer-memaccess -Wno-pointer-sign -Wno-unused-result -Wmisleading-indentation -Wbitwise-instead-of-logical -fno-strict-aliasing -mretpoline -ftrapv -fzero-call-used-regs=all -fno-builtin-memset -fstack-protector-strong -fPIE -I. -I. -D_XOPEN_SOURCE=600 -D_BSD_SOURCE -D_DEFAULT_SOURCE -DSSHDIR=\"/etc/ssh\" -D_PATH_SSH_PROGRAM=\"/usr/bin/ssh\" -D_PATH_SSH_ASKPASS_DEFAULT=\"/usr/lib/misc/ssh-askpass\" -D_PATH_SFTP_SERVER=\"/usr/lib/misc/sftp-server\" -D_PATH_SSH_KEY_SIGN=\"/usr/lib/misc/ssh-keysign\" -D_PATH_SSH_PKCS11_HELPER=\"/usr/lib/misc/ssh-pkcs11-helper\" -D_PATH_SSH_SK_HELPER=\"/usr/lib/misc/ssh-sk-helper\" -D_PATH_SSH_PIDDIR=\"/run\" -D_PATH_PRIVSEP_CHROOT_DIR=\"/var/empty\" -DHAVE_CONFIG_H -c cipher-aes.c -o cipher-aes.o do not support implicit function declarations [-Wimplicit-function-declaration] ret = vsnprintf(string, INIT_SZ, fmt, ap2); ^ bsd-asprintf.c:51:8: note: include the header <stdio.h> or explicitly provide a declaration for 'vsnprintf' 1 error generated. ``` * upstream: notifier_complete(NULL, ...) is a noop, so no need to test that ctx!=NULL; from Corinna Vinschen OpenBSD-Commit-ID: ade2f2e9cc519d01a586800c25621d910bce384a * upstream: fix repeated words ok miod@ jmc@ OpenBSD-Commit-ID: 6765daefe26a6b648cc15cadbbe337596af709b7 * upstream: .Li -> .Vt where appropriate; from josiah frentsos, tweaked by schwarze ok schwarze OpenBSD-Commit-ID: 565046e3ce68b46c2f440a93d67c2a92726de8ed * upstream: ssh-agent: attempt FIDO key signing without PIN and use the error to determine whether a PIN is required and prompt only if necessary. from Corinna Vinschen OpenBSD-Commit-ID: dd6be6a0b7148608e834ee737c3479b3270b00dd * upstream: a little extra debugging OpenBSD-Commit-ID: edf1601c1d0905f6da4c713f4d9cecc7d1c0295a * upstream: sk_enroll: never drop SSH_SK_USER_VERIFICATION_REQD flag from response Now that all FIDO signing calls attempt first without PIN and then fall back to trying PIN only if that attempt fails, we can remove the hack^wtrick that removed the UV flag from the keys returned during enroll.

From Michal Privoznik OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a * upstream: sftp: Be a bit more clever about completions There are commands (e.g. "get" or "put") that accept two arguments, a local path and a remote path. However, the way current completion is written doesn't take this distinction into account and always completes remote or local paths. By expanding CMD struct and "cmds" array this distinction can be reflected and with small adjustment to completer code the correct path can be completed.

Increase to 600 (10h). * Fix compat regress to work with non-GNU make. * Link libssh into compat tests. The cygwin compat code uses xmalloc, so add libssh.a so pick up that. * Rerun tests on changes to Makefile.in in any dir. * upstream: replace recently-added valid_domain() check for hostnames going to known_hosts with a more relaxed check for bad characters; previous commit broke address literals.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match. Initial investigation by Daniel Pouzzner (douzzer at mega nu), workaround suggested by Bill Wendling (morbo at google com). bz#3475, ok djm@ * upstream: In channel_request_remote_forwarding the parameters for permission_set_add are leaked as they are also duplicated in the call.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic). So this adds an extra "force" argument to the channel cleanup callback to indicate this condition. ok markus dtucker OpenBSD-Commit-ID: 23052707a42bdc62fda2508636e624afd466324b * upstream: tweak channel ctype names These are now used by sshd_config:ChannelTimeouts to specify timeouts by channel type, so force them all to use a similar format without whitespace. ok dtucker markus OpenBSD-Commit-ID: 66834765bb4ae14f96d2bb981ac98a7dae361b65 * upstream: Add channel_set_xtype() This sets an "extended" channel type after channel creation (e.g. "session:subsystem:sftp") that will be used for setting channel inactivity timeouts. ok markus dtucker OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca * upstream: Implement channel inactivity timeouts This adds a sshd_config ChannelTimeouts directive that allows channels that have not seen traffic in a configurable interval to be automatically closed. Different timeouts may be applied to session, X11, agent and TCP forwarding channels. Note: this only affects channels over an opened SSH connection and not the connection itself. Most clients close the connection when their channels go away, with a notable exception being ssh(1) in multiplexing mode. ok markus dtucker OpenBSD-Commit-ID: ae8bba3ed9d9f95ff2e2dc8dcadfa36b48e6c0b8 * unbreak scp on NetBSD 4.x e555d5cad5 effectively increased the default copy buffer size for SFTP transfers.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

So this adds an extra "force" argument to the channel cleanup callback to indicate this condition. ok markus dtucker OpenBSD-Commit-ID: 23052707a42bdc62fda2508636e624afd466324b * upstream: tweak channel ctype names These are now used by sshd_config:ChannelTimeouts to specify timeouts by channel type, so force them all to use a similar format without whitespace. ok dtucker markus OpenBSD-Commit-ID: 66834765bb4ae14f96d2bb981ac98a7dae361b65 * upstream: Add channel_set_xtype() This sets an "extended" channel type after channel creation (e.g. "session:subsystem:sftp") that will be used for setting channel inactivity timeouts. ok markus dtucker OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca * upstream: Implement channel inactivity timeouts This adds a sshd_config ChannelTimeouts directive that allows channels that have not seen traffic in a configurable interval to be automatically closed. Different timeouts may be applied to session, X11, agent and TCP forwarding channels. Note: this only affects channels over an opened SSH connection and not the connection itself. Most clients close the connection when their channels go away, with a notable exception being ssh(1) in multiplexing mode. ok markus dtucker OpenBSD-Commit-ID: ae8bba3ed9d9f95ff2e2dc8dcadfa36b48e6c0b8 * unbreak scp on NetBSD 4.x e555d5cad5 effectively increased the default copy buffer size for SFTP transfers. This caused NetBSD 4.x to hang during the "copy local file to remote file in place" scp.sh regression test. This puts back the original 32KB copy buffer size until we can properly figure out why. lots of debugging assistance from dtucker@ * upstream: Copy bytes from the_banana[] rather than banana() Fixes test failure due to segfault seen on arm64 with xonly snap. ok djm OpenBSD-Regress-ID: 86e2aa4bbd1dff1bc4ebb2969c0d6474485be046 * upstream: unit tests for misc.c:ptimeout_* API OpenBSD-Regress-ID: 01f8fb12d08e5aaadd4bd4e71f456b6588be9a94 * upstream: fix typo in verbose logging OpenBSD-Regress-ID: 0497cdb66e003b2f50ed77291a9104fba2e017e9 * upstream: regression test for ChannelTimeout OpenBSD-Regress-ID: 280bfbefcfa415428ad744e43f69a8dede8ad685 * upstream: Save debug logs from ssh for debugging purposes. OpenBSD-Regress-ID: 109e40b06de1c006a3b8e0d8745b790b2c5870a0 * Set OPENSSL_BIN from OpenSSL directory. * Check openssl_bin path is executable before using. * Use autoconf to find openssl binary. It's possible to install an OpenSSL in a path not in the system's default library search path. OpenSSH can still use this (eg if you specify an rpath) but the openssl binary there may not work. If one is available on the system path just use that. * Use our own netcat for dynamic-forward test. That way we can be surer about its behaviour rather than trying to second-guess the behaviour of various netcat implementations. * upstream: When OpenSSL is not available, skip parts of percent test that require it. Based on github pr#368 from ren mingshuai. OpenBSD-Regress-ID: 49a375b2cf61ccb95b52e75e2e025cd10988ebb2 * don't test IPv6 addresses if platform lacks support * Skip dynamic-forward test on minix3. This test relies on loopback addresses which minix does not have. Previously the test would not run at all since it also doesn't have netcat, but now we use our own netcat it tries and fails. * try to improve logging for dynamic-forward test previously the logs from the ssh used to exercise the forwarding channel would clobber the logs from the ssh actually doing the forwarding * upstream: tweak previous; ok djm OpenBSD-Commit-ID: 229c493452766d70a78b0f02f6ff9894f9028858 * upstream: Switch scp from using pipes to a socketpair for communication with it's ssh sub-processes. We no longer need to reserve two descriptors to ensure that we don't end up using fd 0-2 unexpectedly, that is handled by sanitise_stdfd() in main(). Based on an original diff from djm@. OK deraadt@ djm@ OpenBSD-Commit-ID: b80c372faac462471e955ddeab9480d668a2e48d * add back use of pipes in scp.c under USE_PIPES This matches sftp.c which prefers socketpair but uses pipes on some older platforms. * remove buffer len workaround for NetBSD 4.x Switching to from pipes to a socketpair for communicating with the ssh process avoids the (kernel bug?) problem. * upstream: rewrite this test to use a multiplexed ssh session so we can control its lifecycle without risk of race conditions; fixes some of the Github integration tests for openssh-portable OpenBSD-Regress-ID: 5451cad59ba0d43ae9eeda48ec80f54405fee969 * upstream: remove whitespace at EOL from code extracted from SUPERCOP OpenBSD-Commit-ID: 1ec524ff2fbb9387d731601437c82008f35a60f4 * upstream: ignore bogus upload/download buffer lengths in the limits extension OpenBSD-Commit-ID: c5b023e0954693ba9a5376e4280c739b5db575f8 * upstream: clamp the minimum buffer lengths and number of inflight requests too OpenBSD-Commit-ID: c4965f62fa0ba850940fd66ae3f60cf516bbcd56 * upstream: avoid printf("%s", NULL) if using ssh -oUserKnownHostsFile=none and a hostkey in one of the system known hosts file changes; ok dtucker@ OpenBSD-Commit-ID: 7ca87614bfc6da491315536a7f2301434a9fe614 * upstream: Add a "Host" line to the output of ssh -G showing the original host arg. Inspired by patch from vincent at bernat.ch via bz#3343, ok djm@ OpenBSD-Commit-ID: 59c0f60a222113a44d0650cd394376e3beecc883 * Remove skipping test when scp not in path. An upcoming change renders this obsolete by adding scp's path to the test sshd's PATH, and removing this first will make the subsequent sync easier. * upstream: Add scp's path to test sshd's PATH. If the scp we're testing is fully qualified (eg it's not in the system PATH) then add its path to the under-test sshd's PATH so we can find it. Prompted by bz#3518. OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0 * upstream: Move scp path setting to a helper function. The previous commit to add scp to the test sshd's path causes the t-envpass test to fail when the test scp is given using a fully qualified path. Put this in a helper function and only call it from the scp tests. OpenBSD-Regress-ID: 7533dc1c4265c1de716abb062957994195b36df4 * Retry package installation 3 times. When setting up the CI environment, retry package installation 3 times before going up. Should help prevent spurious failures during infrastructure issues. * upstream: Document "UserKnownHostsFile none". ok djm@ OpenBSD-Commit-ID: f695742d39e34ecdcc3c861c3739a84648a4bce5 * upstream: fix double phrase in previous; OpenBSD-Commit-ID: 671e6c8dc5e9230518b2bbfa143daaa88adc66c2 * upstream: Instead of skipping the all-tokens test if we don't have OpenSSL (since we use it to compute the hash), put the hash at the end and just omit it if we don't have it. Prompted by bz#3521. OpenBSD-Regress-ID: c79ecba64250ed3b6417294b6c965e6b12ca5eea * upstream: Shell syntax fix. From ren mingshuai vi github PR#369.

From bz#3512, ok djm@ * upstream: update OpenSSH's Ed25519 code to the last version of SUPERCOP (20221122) and change the import approach to the same one we use for Streamlined NTRUPrime: use a shell script to extract the bits we need from SUPERCOP, make some minor adjustments and squish them all into a single file. ok tb@ tobhe@ OpenBSD-Commit-ID: 1bc0fd624cb6af440905b8ba74ac7c03311b8e3b * upstream: adapt to ed25519 changes in src/usr.bin/ssh OpenBSD-Regress-ID: 4b3e7ba7ee486ae8a0b4790f8112eded2bb7dcd5 * upstream: Add a sshd_config UnusedConnectionTimeout option to terminate client connections that have no open channels for some length of time. This complements the recently-added ChannelTimeout option that terminates inactive channels after a timeout. ok markus@ OpenBSD-Commit-ID: ca983be74c0350364c11f8ba3bd692f6f24f5da9 * upstream: unbreak test: cannot access shell positional parameters past $9 without wrapping the position in braces (i.e. need ${10}, etc.) OpenBSD-Regress-ID: 3750ec98d5d409ce6a93406fedde6f220d2ea2ac * upstream: regression test for UnusedConnectionTimeout OpenBSD-Regress-ID: 7f29001374a68e71e5e078f69e4520cf4bcca084 * upstream: also check that an active session inhibits UnusedConnectionTimeout idea markus@ OpenBSD-Regress-ID: 55c0fb61f3bf9e092b0a53f9041d3d2012f14003 * upstream: For "ssh -V" always exit 0, there is no need to check opt again. This was missed when the fallthrough in the switch case above it was removed. OK deraadt@ OpenBSD-Commit-ID: 5583e5d8f6d62a8a4215cfa95a69932f344c8120 * upstream: Add a -V (version) option to sshd like the ssh client has. OK markus@ deraadt@ OpenBSD-Commit-ID: abe990ec3e636fb040132aab8cbbede98f0c413e * upstream: when restoring non-blocking mode to stdio fds, restore exactly the flags that ssh started with and don't just clobber them with zero, as this could also remove the append flag from the set; bz3523; ok dtucker@ OpenBSD-Commit-ID: 1336b03e881db7564a4b66014eb24c5230e9a0c0 * Skip connection-timeout when missing FD passing. This tests uses multiplexing which uses file descriptor passing, so skip it if we don't have that. Fixes test failures on Cygwin. * Skip connection-timeout test under Valgrind. Valgrind slows things down so much that the timeout test fails. Skip this test until we figure out if we can make it work. * upstream: tweak previous; ok djm OpenBSD-Commit-ID: df71ce4180c58202dfdc1d92626cfe900b91b7c3 * upstream: Create and install sshd random relink kit. ../Makefile.inc and Makfile are concatenated for reuse, which hopefully won't be too fragile, we'll see if we need a different approach. The resulting sshd binary is tested with the new sshd -V option before installation. As the binary layout is now semi-unknown (meaning relative, fixed, and gadget offsets are not precisely known), change the filesystem permissions to 511 to prevent what I call "logged in BROP". I have ideas for improving this further but this is a first step ok djm OpenBSD-Commit-ID: 1e0a2692b7e20b126dda60bf04999d1d30d959d8 * upstream: delete useless dependency OpenBSD-Commit-ID: e1dc11143f83082e3154d6094f9136d0dc2637ad * fix libfido2 detection without pkg-config Place libfido2 before additional libraries (that it may depend upon) and not after. bz3530 from James Zhang; ok dtucker@ * Skip connection-timeout test on minix3. Minix 3's Unix domain sockets don't seem to work the way we expect, so skip connection-timeout test on that platform.

From Pedro Martelletto via GHPR#388 OpenBSD-Commit-ID: 007eb7e387d27cf3029ab06b88224e03eca62ccd * Remove arc4random_uniform from arc4random.c This was previously moved into its own file (matching OpenBSD) which prematurely committed in commit 73541f2. * Move OPENBSD ORIGINAL marker. Putting this after the copyright statement (which doesn't change) instead of before the version identifier (which does) prevents merge conflicts when resyncing changes. * Resync arc4random with OpenBSD. This brings us up to current, including djm's random-reseeding change, as prompted by logan at cyberstorm.mu in bz#3467. It brings the platform-specific hooks from LibreSSL Portable, simplified to match our use case. ok djm@. * Remove DEF_WEAK, it's already in defines.h. * openbsd-compat/bsd-asprintf: add <stdio.h> include for vsnprintf Fixes the following build failure with Clang 15 on musl: ``` bsd-asprintf.c:51:8: error: call to undeclared library function 'vsnprintf' with type 'int (char *, unsigned long, const char *, struct __va_list_tag *)'; ISO C99 and laterclang -O2 -pipe -fdiagnostics-color=always -frecord-gcc-switches -pipe -Wunknown-warning-option -Qunused-arguments -Wall -Wpointer-arith -Wuninitialized -Wsign-compare -Wformat-security -Wsizeof-pointer-memaccess -Wno-pointer-sign -Wno-unused-result -Wmisleading-indentation -Wbitwise-instead-of-logical -fno-strict-aliasing -mretpoline -ftrapv -fzero-call-used-regs=all -fno-builtin-memset -fstack-protector-strong -fPIE -I. -I. -D_XOPEN_SOURCE=600 -D_BSD_SOURCE -D_DEFAULT_SOURCE -DSSHDIR=\"/etc/ssh\" -D_PATH_SSH_PROGRAM=\"/usr/bin/ssh\" -D_PATH_SSH_ASKPASS_DEFAULT=\"/usr/lib/misc/ssh-askpass\" -D_PATH_SFTP_SERVER=\"/usr/lib/misc/sftp-server\" -D_PATH_SSH_KEY_SIGN=\"/usr/lib/misc/ssh-keysign\" -D_PATH_SSH_PKCS11_HELPER=\"/usr/lib/misc/ssh-pkcs11-helper\" -D_PATH_SSH_SK_HELPER=\"/usr/lib/misc/ssh-sk-helper\" -D_PATH_SSH_PIDDIR=\"/run\" -D_PATH_PRIVSEP_CHROOT_DIR=\"/var/empty\" -DHAVE_CONFIG_H -c cipher-aes.c -o cipher-aes.o do not support implicit function declarations [-Wimplicit-function-declaration] ret = vsnprintf(string, INIT_SZ, fmt, ap2); ^ bsd-asprintf.c:51:8: note: include the header <stdio.h> or explicitly provide a declaration for 'vsnprintf' 1 error generated. ``` * upstream: notifier_complete(NULL, ...) is a noop, so no need to test that ctx!=NULL; from Corinna Vinschen OpenBSD-Commit-ID: ade2f2e9cc519d01a586800c25621d910bce384a * upstream: fix repeated words ok miod@ jmc@ OpenBSD-Commit-ID: 6765daefe26a6b648cc15cadbbe337596af709b7 * upstream: .Li -> .Vt where appropriate; from josiah frentsos, tweaked by schwarze ok schwarze OpenBSD-Commit-ID: 565046e3ce68b46c2f440a93d67c2a92726de8ed * upstream: ssh-agent: attempt FIDO key signing without PIN and use the error to determine whether a PIN is required and prompt only if necessary. from Corinna Vinschen OpenBSD-Commit-ID: dd6be6a0b7148608e834ee737c3479b3270b00dd * upstream: a little extra debugging OpenBSD-Commit-ID: edf1601c1d0905f6da4c713f4d9cecc7d1c0295a * upstream: sk_enroll: never drop SSH_SK_USER_VERIFICATION_REQD flag from response Now that all FIDO signing calls attempt first without PIN and then fall back to trying PIN only if that attempt fails, we can remove the hack^wtrick that removed the UV flag from the keys returned during enroll.

However, the way current completion is written doesn't take this distinction into account and always completes remote or local paths. By expanding CMD struct and "cmds" array this distinction can be reflected and with small adjustment to completer code the correct path can be completed.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic).

Merge 9.2 (#657) * upstream: attemp FIDO key signing without PIN and use the error code returned to fall back only if necessary. Avoids PIN prompts for FIDO tokens that don't require them; part of GHPR#302 OpenBSD-Commit-ID: 4f752aaf9f2e7c28bcaaf3d4f8fc290131bd038e * Install Cygwin packages based on OS not config. * initial list of allowed signers * upstream: whitespace OpenBSD-Commit-ID: d297e4387935d4aef091c5e9432578c2e513f538 * upstream: whitespace OpenBSD-Commit-ID: a5d015efbfd228dc598ffdef612d2da3a579e5d8 * Add cygwin-release test target. This also moves the cygwin package install from the workflow file to setup_ci.sh so that we can install different sets of Cygwin packages for different test configs. * Add Windows 2022 test targets. * Add libcrypt-devel to cygwin-release deps. Based on feedback from vinschen at redhat.com. * cross-sign allowed_signers with PGP key Provides continuity of trust from legacy PGP release key to the SSHSIG signing keys that we will use henceforth for git signing. * additional keys * upstream: whitespace OpenBSD-Commit-ID: c2bcbf93610d3d62ed206cdf9bf9ff98c6aaf232 * Move sftp from valgrind-2 to 3 to rebalance. * upstream: sk-usbhid: fix key_lookup() on tokens with built-in UV explicitly test whether the token performs built-in UV (e.g. biometric tokens) and enable UV in that case. From Pedro Martelletto via GHPR#388 OpenBSD-Commit-ID: 007eb7e387d27cf3029ab06b88224e03eca62ccd * Remove arc4random_uniform from arc4random.c This was previously moved into its own file (matching OpenBSD) which prematurely committed in commit 73541f2. * Move OPENBSD ORIGINAL marker. Putting this after the copyright statement (which doesn't change) instead of before the version identifier (which does) prevents merge conflicts when resyncing changes. * Resync arc4random with OpenBSD. This brings us up to current, including djm's random-reseeding change, as prompted by logan at cyberstorm.mu in bz#3467. It brings the platform-specific hooks from LibreSSL Portable, simplified to match our use case. ok djm@. * Remove DEF_WEAK, it's already in defines.h. * openbsd-compat/bsd-asprintf: add <stdio.h> include for vsnprintf Fixes the following build failure with Clang 15 on musl: ``` bsd-asprintf.c:51:8: error: call to undeclared library function 'vsnprintf' with type 'int (char *, unsigned long, const char *, struct __va_list_tag *)'; ISO C99 and laterclang -O2 -pipe -fdiagnostics-color=always -frecord-gcc-switches -pipe -Wunknown-warning-option -Qunused-arguments -Wall -Wpointer-arith -Wuninitialized -Wsign-compare -Wformat-security -Wsizeof-pointer-memaccess -Wno-pointer-sign -Wno-unused-result -Wmisleading-indentation -Wbitwise-instead-of-logical -fno-strict-aliasing -mretpoline -ftrapv -fzero-call-used-regs=all -fno-builtin-memset -fstack-protector-strong -fPIE -I. -I. -D_XOPEN_SOURCE=600 -D_BSD_SOURCE -D_DEFAULT_SOURCE -DSSHDIR=\"/etc/ssh\" -D_PATH_SSH_PROGRAM=\"/usr/bin/ssh\" -D_PATH_SSH_ASKPASS_DEFAULT=\"/usr/lib/misc/ssh-askpass\" -D_PATH_SFTP_SERVER=\"/usr/lib/misc/sftp-server\" -D_PATH_SSH_KEY_SIGN=\"/usr/lib/misc/ssh-keysign\" -D_PATH_SSH_PKCS11_HELPER=\"/usr/lib/misc/ssh-pkcs11-helper\" -D_PATH_SSH_SK_HELPER=\"/usr/lib/misc/ssh-sk-helper\" -D_PATH_SSH_PIDDIR=\"/run\" -D_PATH_PRIVSEP_CHROOT_DIR=\"/var/empty\" -DHAVE_CONFIG_H -c cipher-aes.c -o cipher-aes.o do not support implicit function declarations [-Wimplicit-function-declaration] ret = vsnprintf(string, INIT_SZ, fmt, ap2); ^ bsd-asprintf.c:51:8: note: include the header <stdio.h> or explicitly provide a declaration for 'vsnprintf' 1 error generated. ``` * upstream: notifier_complete(NULL, ...) is a noop, so no need to test that ctx!=NULL; from Corinna Vinschen OpenBSD-Commit-ID: ade2f2e9cc519d01a586800c25621d910bce384a * upstream: fix repeated words ok miod@ jmc@ OpenBSD-Commit-ID: 6765daefe26a6b648cc15cadbbe337596af709b7 * upstream: .Li -> .Vt where appropriate; from josiah frentsos, tweaked by schwarze ok schwarze OpenBSD-Commit-ID: 565046e3ce68b46c2f440a93d67c2a92726de8ed * upstream: ssh-agent: attempt FIDO key signing without PIN and use the error to determine whether a PIN is required and prompt only if necessary. from Corinna Vinschen OpenBSD-Commit-ID: dd6be6a0b7148608e834ee737c3479b3270b00dd * upstream: a little extra debugging OpenBSD-Commit-ID: edf1601c1d0905f6da4c713f4d9cecc7d1c0295a * upstream: sk_enroll: never drop SSH_SK_USER_VERIFICATION_REQD flag from response Now that all FIDO signing calls attempt first without PIN and then fall back to trying PIN only if that attempt fails, we can remove the hack^wtrick that removed the UV flag from the keys returned during enroll.

From Michal Privoznik OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a * upstream: sftp: Be a bit more clever about completions There are commands (e.g. "get" or "put") that accept two arguments, a local path and a remote path. However, the way current completion is written doesn't take this distinction into account and always completes remote or local paths. By expanding CMD struct and "cmds" array this distinction can be reflected and with small adjustment to completer code the correct path can be completed.

From emaste at freebsd.org. * Defer seed_rng until after closefrom call. seed_rng will initialize OpenSSL, and some engine providers (eg Intel's QAT) will open descriptors for their own use. bz#3483, patch from joel.d.schuetze at intel.com, ok djm@ * upstream: typo in comment OpenBSD-Commit-ID: 39c58f41e0f32d1ff31731fa6f5bbbc3ad25084a * upstream: rename client_global_hostkeys_private_confirm() to client_global_hostkeys_prove_confirm(), as it handles the "hostkeys-prove00@openssh.com" message; no functional change OpenBSD-Commit-ID: 31e09bd3cca6eed26855b88fb8beed18e9bd026d * upstream: Remove errant colon and simplify format string in error messages.

OpenBSD-Commit-ID: 8a0c164a6a25eef0eedfc30df95bfa27644e35cf * Skip reexec test on OpenSSL 1.1.1 specifically. OpenSSL 1.1.1 has a bug in its RNG that breaks reexec fallback, so skip that test. See bz#3483 for details. * Remove seed passing over reexec. This was added for the benefit of platforms using ssh-rand-helper to prevent a delay on each connection as sshd reseeded itself. ssh-random-helper is long gone, and since the re-exec happens before the chroot the re-execed sshd can reseed itself normally. ok djm@ * upstream: Handle dynamic remote port forwarding in escape commandline's -R processing. bz#3499, ok djm@ OpenBSD-Commit-ID: 194ee4cfe7ed0e2b8ad0727f493c798a50454208 * Add dfly62 test target. * If we haven't found it yet, recheck for sys/stat.h. On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic). So this adds an extra "force" argument to the channel cleanup callback to indicate this condition. ok markus dtucker OpenBSD-Commit-ID: 23052707a42bdc62fda2508636e624afd466324b * upstream: tweak channel ctype names These are now used by sshd_config:ChannelTimeouts to specify timeouts by channel type, so force them all to use a similar format without whitespace. ok dtucker markus OpenBSD-Commit-ID: 66834765bb4ae14f96d2bb981ac98a7dae361b65 * upstream: Add channel_set_xtype() This sets an "extended" channel type after channel creation (e.g. "session:subsystem:sftp") that will be used for setting channel inactivity timeouts. ok markus dtucker OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca * upstream: Implement channel inactivity timeouts This adds a sshd_config ChannelTimeouts directive that allows channels that have not seen traffic in a configurable interval to be automatically closed.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

OpenBSD-Regress-ID: 3b04faced6511bb5e74648c6a4ef4bf2c4decf03 * upstream: remove '?' from getopt(3) loops userspace: remove vestigial '?' cases from top-level getopt(3) loops getopt(3) returns '?' when it encounters a flag not present in the in the optstring or if a flag is missing its option argument. We can handle this case with the "default" failure case with no loss of legibility. Hence, remove all the redundant "case '?':" lines. Prompted by dlg@. With help from dlg@ and millert@. Link: https://marc.info/?l=openbsd-tech&m=167011979726449&w=2 ok naddy@ millert@ dlg@ OpenBSD-Commit-ID: b2f89346538ce4f5b33ab8011a23e0626a67e66e * upstream: Add server debugging for hostbased auth. auth_debug_add queues messages about the auth process which is sent to the client after successful authentication. This also sends those to the server debug log to aid in debugging. From bz#3507, ok djm@ OpenBSD-Commit-ID: 46ff67518cccf9caf47e06393e2a121ee5aa258a * upstream: Warn if no host keys for hostbased auth can be loaded.

This ensures that the tests don't fail due to StrictMode checks. * Use sudo when resetting perms on directories. * Add tests for LibreSSL 3.7.0 and OpenSSL 1.1.1s. * Simply handling of SSH_CONNECTION PAM env var. Prompted by bz#3508: there's no need to cache the value of sshpam_conninfo so remove the global. While there, add check of return value from pam_putenv. ok djm@ * upstream: The idiomatic way of coping with signed char vs unsigned char (which did not come from stdio read functions) in the presence of ctype macros, is to always cast to (unsigned char). casting to (int) for a "macro" which is documented to take int, is weird. And sadly wrong, because of the sing extension risk.. same diff from florian OpenBSD-Commit-ID: 65b9a49a68e22ff3a0ebd593f363e9f22dd73fea * upstream: add a -X option to both scp(1) and sftp(1) to allow control over some SFTP protocol knobs: the copy buffer length and the number of inflight requests, both of which are used during upload/download. Previously these could be controlled in sftp(1) using the -b/-R options. This makes them available in both SFTP protocol clients using the same option character sequence. ok dtucker@ OpenBSD-Commit-ID: 27502bffc589776f5da1f31df8cb51abe9a15f1c * upstream: add -X to usage(); OpenBSD-Commit-ID: 1bdc3df7de11d766587b0428318336dbffe4a9d0 * upstream: Clear signal mask early in main(); sshd may have been started with one or more signals masked (sigprocmask(2) is not cleared on fork/exec) and this could interfere with various things, e.g. the login grace timer. Execution environments that fail to clear the signal mask before running sshd are clearly broken, but apparently they do exist. Reported by Sreedhar Balasubramanian; ok dtucker@ OpenBSD-Commit-ID: 77078c0b1c53c780269fc0c416f121d05e3010ae * upstream: Mention that scp uses the SFTP protocol and remove reference to legacy flag.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic). So this adds an extra "force" argument to the channel cleanup callback to indicate this condition. ok markus dtucker OpenBSD-Commit-ID: 23052707a42bdc62fda2508636e624afd466324b * upstream: tweak channel ctype names These are now used by sshd_config:ChannelTimeouts to specify timeouts by channel type, so force them all to use a similar format without whitespace. ok dtucker markus OpenBSD-Commit-ID: 66834765bb4ae14f96d2bb981ac98a7dae361b65 * upstream: Add channel_set_xtype() This sets an "extended" channel type after channel creation (e.g. "session:subsystem:sftp") that will be used for setting channel inactivity timeouts. ok markus dtucker OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca * upstream: Implement channel inactivity timeouts This adds a sshd_config ChannelTimeouts directive that allows channels that have not seen traffic in a configurable interval to be automatically closed. Different timeouts may be applied to session, X11, agent and TCP forwarding channels. Note: this only affects channels over an opened SSH connection and not the connection itself. Most clients close the connection when their channels go away, with a notable exception being ssh(1) in multiplexing mode. ok markus dtucker OpenBSD-Commit-ID: ae8bba3ed9d9f95ff2e2dc8dcadfa36b48e6c0b8 * unbreak scp on NetBSD 4.x e555d5cad5 effectively increased the default copy buffer size for SFTP transfers. This caused NetBSD 4.x to hang during the "copy local file to remote file in place" scp.sh regression test. This puts back the original 32KB copy buffer size until we can properly figure out why. lots of debugging assistance from dtucker@ * upstream: Copy bytes from the_banana[] rather than banana() Fixes test failure due to segfault seen on arm64 with xonly snap. ok djm OpenBSD-Regress-ID: 86e2aa4bbd1dff1bc4ebb2969c0d6474485be046 * upstream: unit tests for misc.c:ptimeout_* API OpenBSD-Regress-ID: 01f8fb12d08e5aaadd4bd4e71f456b6588be9a94 * upstream: fix typo in verbose logging OpenBSD-Regress-ID: 0497cdb66e003b2f50ed77291a9104fba2e017e9 * upstream: regression test for ChannelTimeout OpenBSD-Regress-ID: 280bfbefcfa415428ad744e43f69a8dede8ad685 * upstream: Save debug logs from ssh for debugging purposes. OpenBSD-Regress-ID: 109e40b06de1c006a3b8e0d8745b790b2c5870a0 * Set OPENSSL_BIN from OpenSSL directory. * Check openssl_bin path is executable before using. * Use autoconf to find openssl binary. It's possible to install an OpenSSL in a path not in the system's default library search path. OpenSSH can still use this (eg if you specify an rpath) but the openssl binary there may not work. If one is available on the system path just use that. * Use our own netcat for dynamic-forward test. That way we can be surer about its behaviour rather than trying to second-guess the behaviour of various netcat implementations. * upstream: When OpenSSL is not available, skip parts of percent test that require it. Based on github pr#368 from ren mingshuai. OpenBSD-Regress-ID: 49a375b2cf61ccb95b52e75e2e025cd10988ebb2 * don't test IPv6 addresses if platform lacks support * Skip dynamic-forward test on minix3. This test relies on loopback addresses which minix does not have. Previously the test would not run at all since it also doesn't have netcat, but now we use our own netcat it tries and fails. * try to improve logging for dynamic-forward test previously the logs from the ssh used to exercise the forwarding channel would clobber the logs from the ssh actually doing the forwarding * upstream: tweak previous; ok djm OpenBSD-Commit-ID: 229c493452766d70a78b0f02f6ff9894f9028858 * upstream: Switch scp from using pipes to a socketpair for communication with it's ssh sub-processes. We no longer need to reserve two descriptors to ensure that we don't end up using fd 0-2 unexpectedly, that is handled by sanitise_stdfd() in main(). Based on an original diff from djm@. OK deraadt@ djm@ OpenBSD-Commit-ID: b80c372faac462471e955ddeab9480d668a2e48d * add back use of pipes in scp.c under USE_PIPES This matches sftp.c which prefers socketpair but uses pipes on some older platforms. * remove buffer len workaround for NetBSD 4.x Switching to from pipes to a socketpair for communicating with the ssh process avoids the (kernel bug?) problem. * upstream: rewrite this test to use a multiplexed ssh session so we can control its lifecycle without risk of race conditions; fixes some of the Github integration tests for openssh-portable OpenBSD-Regress-ID: 5451cad59ba0d43ae9eeda48ec80f54405fee969 * upstream: remove whitespace at EOL from code extracted from SUPERCOP OpenBSD-Commit-ID: 1ec524ff2fbb9387d731601437c82008f35a60f4 * upstream: ignore bogus upload/download buffer lengths in the limits extension OpenBSD-Commit-ID: c5b023e0954693ba9a5376e4280c739b5db575f8 * upstream: clamp the minimum buffer lengths and number of inflight requests too OpenBSD-Commit-ID: c4965f62fa0ba850940fd66ae3f60cf516bbcd56 * upstream: avoid printf("%s", NULL) if using ssh -oUserKnownHostsFile=none and a hostkey in one of the system known hosts file changes; ok dtucker@ OpenBSD-Commit-ID: 7ca87614bfc6da491315536a7f2301434a9fe614 * upstream: Add a "Host" line to the output of ssh -G showing the original host arg. Inspired by patch from vincent at bernat.ch via bz#3343, ok djm@ OpenBSD-Commit-ID: 59c0f60a222113a44d0650cd394376e3beecc883 * Remove skipping test when scp not in path. An upcoming change renders this obsolete by adding scp's path to the test sshd's PATH, and removing this first will make the subsequent sync easier. * upstream: Add scp's path to test sshd's PATH. If the scp we're testing is fully qualified (eg it's not in the system PATH) then add its path to the under-test sshd's PATH so we can find it. Prompted by bz#3518. OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0 * upstream: Move scp path setting to a helper function. The previous commit to add scp to the test sshd's path causes the t-envpass test to fail when the test scp is given using a fully qualified path. Put this in a helper function and only call it from the scp tests. OpenBSD-Regress-ID: 7533dc1c4265c1de716abb062957994195b36df4 * Retry package installation 3 times. When setting up the CI environment, retry package installation 3 times before going up. Should help prevent spurious failures during infrastructure issues. * upstream: Document "UserKnownHostsFile none". ok djm@ OpenBSD-Commit-ID: f695742d39e34ecdcc3c861c3739a84648a4bce5 * upstream: fix double phrase in previous; OpenBSD-Commit-ID: 671e6c8dc5e9230518b2bbfa143daaa88adc66c2 * upstream: Instead of skipping the all-tokens test if we don't have OpenSSL (since we use it to compute the hash), put the hash at the end and just omit it if we don't have it. Prompted by bz#3521. OpenBSD-Regress-ID: c79ecba64250ed3b6417294b6c965e6b12ca5eea * upstream: Shell syntax fix. From ren mingshuai vi github PR#369. OpenBSD-Regress-ID: 6696b2eeefe128099fc3d7ea9f23252cc35156f9 * Allow writev is seccomp sandbox. This seems to be used by recent glibcs at least in some configurations. From bz#3512, ok djm@ * upstream: update OpenSSH's Ed25519 code to the last version of SUPERCOP (20221122) and change the import approach to the same one we use for Streamlined NTRUPrime: use a shell script to extract the bits we need from SUPERCOP, make some minor adjustments and squish them all into a single file. ok tb@ tobhe@ OpenBSD-Commit-ID: 1bc0fd624cb6af440905b8ba74ac7c03311b8e3b * upstream: adapt to ed25519 changes in src/usr.bin/ssh OpenBSD-Regress-ID: 4b3e7ba7ee486ae8a0b4790f8112eded2bb7dcd5 * upstream: Add a sshd_config UnusedConnectionTimeout option to terminate client connections that have no open channels for some length of time. This complements the recently-added ChannelTimeout option that terminates inactive channels after a timeout. ok markus@ OpenBSD-Commit-ID: ca983be74c0350364c11f8ba3bd692f6f24f5da9 * upstream: unbreak test: cannot access shell positional parameters past $9 without wrapping the position in braces (i.e. need ${10}, etc.) OpenBSD-Regress-ID: 3750ec98d5d409ce6a93406fedde6f220d2ea2ac * upstream: regression test for UnusedConnectionTimeout OpenBSD-Regress-ID: 7f29001374a68e71e5e078f69e4520cf4bcca084 * upstream: also check that an active session inhibits UnusedConnectionTimeout idea markus@ OpenBSD-Regress-ID: 55c0fb61f3bf9e092b0a53f9041d3d2012f14003 * upstream: For "ssh -V" always exit 0, there is no need to check opt again. This was missed when the fallthrough in the switch case above it was removed. OK deraadt@ OpenBSD-Commit-ID: 5583e5d8f6d62a8a4215cfa95a69932f344c8120 * upstream: Add a -V (version) option to sshd like the ssh client has. OK markus@ deraadt@ OpenBSD-Commit-ID: abe990ec3e636fb040132aab8cbbede98f0c413e * upstream: when restoring non-blocking mode to stdio fds, restore exactly the flags that ssh started with and don't just clobber them with zero, as this could also remove the append flag from the set; bz3523; ok dtucker@ OpenBSD-Commit-ID: 1336b03e881db7564a4b66014eb24c5230e9a0c0 * Skip connection-timeout when missing FD passing. This tests uses multiplexing which uses file descriptor passing, so skip it if we don't have that. Fixes test failures on Cygwin. * Skip connection-timeout test under Valgrind. Valgrind slows things down so much that the timeout test fails. Skip this test until we figure out if we can make it work. * upstream: tweak previous; ok djm OpenBSD-Commit-ID: df71ce4180c58202dfdc1d92626cfe900b91b7c3 * upstream: Create and install sshd random relink kit. ../Makefile.inc and Makfile are concatenated for reuse, which hopefully won't be too fragile, we'll see if we need a different approach. The resulting sshd binary is tested with the new sshd -V option before installation. As the binary layout is now semi-unknown (meaning relative, fixed, and gadget offsets are not precisely known), change the filesystem permissions to 511 to prevent what I call "logged in BROP". I have ideas for improving this further but this is a first step ok djm OpenBSD-Commit-ID: 1e0a2692b7e20b126dda60bf04999d1d30d959d8 * upstream: delete useless dependency OpenBSD-Commit-ID: e1dc11143f83082e3154d6094f9136d0dc2637ad * fix libfido2 detection without pkg-config Place libfido2 before additional libraries (that it may depend upon) and not after. bz3530 from James Zhang; ok dtucker@ * Skip connection-timeout test on minix3.

From Michal Privoznik OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a * upstream: sftp: Be a bit more clever about completions There are commands (e.g. "get" or "put") that accept two arguments, a local path and a remote path. However, the way current completion is written doesn't take this distinction into account and always completes remote or local paths. By expanding CMD struct and "cmds" array this distinction can be reflected and with small adjustment to completer code the correct path can be completed.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic). So this adds an extra "force" argument to the channel cleanup callback to indicate this condition. ok markus dtucker OpenBSD-Commit-ID: 23052707a42bdc62fda2508636e624afd466324b * upstream: tweak channel ctype names These are now used by sshd_config:ChannelTimeouts to specify timeouts by channel type, so force them all to use a similar format without whitespace. ok dtucker markus OpenBSD-Commit-ID: 66834765bb4ae14f96d2bb981ac98a7dae361b65 * upstream: Add channel_set_xtype() This sets an "extended" channel type after channel creation (e.g. "session:subsystem:sftp") that will be used for setting channel inactivity timeouts. ok markus dtucker OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca * upstream: Implement channel inactivity timeouts This adds a sshd_config ChannelTimeouts directive that allows channels that have not seen traffic in a configurable interval to be automatically closed. Different timeouts may be applied to session, X11, agent and TCP forwarding channels. Note: this only affects channels over an opened SSH connection and not the connection itself. Most clients close the connection when their channels go away, with a notable exception being ssh(1) in multiplexing mode. ok markus dtucker OpenBSD-Commit-ID: ae8bba3ed9d9f95ff2e2dc8dcadfa36b48e6c0b8 * unbreak scp on NetBSD 4.x e555d5cad5 effectively increased the default copy buffer size for SFTP transfers.

It's possible to install an OpenSSL in a path not in the system's default library search path. OpenSSH can still use this (eg if you specify an rpath) but the openssl binary there may not work.

An upcoming change renders this obsolete by adding scp's path to the test sshd's PATH, and removing this first will make the subsequent sync easier. * upstream: Add scp's path to test sshd's PATH. If the scp we're testing is fully qualified (eg it's not in the system PATH) then add its path to the under-test sshd's PATH so we can find it. Prompted by bz#3518. OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0 * upstream: Move scp path setting to a helper function.

The resulting sshd binary is tested with the new sshd -V option before installation. As the binary layout is now semi-unknown (meaning relative, fixed, and gadget offsets are not precisely known), change the filesystem permissions to 511 to prevent what I call "logged in BROP".

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0 * upstream: Move scp path setting to a helper function. The previous commit to add scp to the test sshd's path causes the t-envpass test to fail when the test scp is given using a fully qualified path. Put this in a helper function and only call it from the scp tests. OpenBSD-Regress-ID: 7533dc1c4265c1de716abb062957994195b36df4 * Retry package installation 3 times.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

Avoids PIN prompts for FIDO tokens that don't require them; part of GHPR#302 OpenBSD-Commit-ID: 4f752aaf9f2e7c28bcaaf3d4f8fc290131bd038e * Install Cygwin packages based on OS not config. * initial list of allowed signers * upstream: whitespace OpenBSD-Commit-ID: d297e4387935d4aef091c5e9432578c2e513f538 * upstream: whitespace OpenBSD-Commit-ID: a5d015efbfd228dc598ffdef612d2da3a579e5d8 * Add cygwin-release test target. This also moves the cygwin package install from the workflow file to setup_ci.sh so that we can install different sets of Cygwin packages for different test configs. * Add Windows 2022 test targets. * Add libcrypt-devel to cygwin-release deps.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic). So this adds an extra "force" argument to the channel cleanup callback to indicate this condition. ok markus dtucker OpenBSD-Commit-ID: 23052707a42bdc62fda2508636e624afd466324b * upstream: tweak channel ctype names These are now used by sshd_config:ChannelTimeouts to specify timeouts by channel type, so force them all to use a similar format without whitespace. ok dtucker markus OpenBSD-Commit-ID: 66834765bb4ae14f96d2bb981ac98a7dae361b65 * upstream: Add channel_set_xtype() This sets an "extended" channel type after channel creation (e.g. "session:subsystem:sftp") that will be used for setting channel inactivity timeouts. ok markus dtucker OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca * upstream: Implement channel inactivity timeouts This adds a sshd_config ChannelTimeouts directive that allows channels that have not seen traffic in a configurable interval to be automatically closed. Different timeouts may be applied to session, X11, agent and TCP forwarding channels. Note: this only affects channels over an opened SSH connection and not the connection itself. Most clients close the connection when their channels go away, with a notable exception being ssh(1) in multiplexing mode. ok markus dtucker OpenBSD-Commit-ID: ae8bba3ed9d9f95ff2e2dc8dcadfa36b48e6c0b8 * unbreak scp on NetBSD 4.x e555d5cad5 effectively increased the default copy buffer size for SFTP transfers.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

And sadly wrong, because of the sing extension risk.. same diff from florian OpenBSD-Commit-ID: 65b9a49a68e22ff3a0ebd593f363e9f22dd73fea * upstream: add a -X option to both scp(1) and sftp(1) to allow control over some SFTP protocol knobs: the copy buffer length and the number of inflight requests, both of which are used during upload/download. Previously these could be controlled in sftp(1) using the -b/-R options. This makes them available in both SFTP protocol clients using the same option character sequence. ok dtucker@ OpenBSD-Commit-ID: 27502bffc589776f5da1f31df8cb51abe9a15f1c * upstream: add -X to usage(); OpenBSD-Commit-ID: 1bdc3df7de11d766587b0428318336dbffe4a9d0 * upstream: Clear signal mask early in main(); sshd may have been started with one or more signals masked (sigprocmask(2) is not cleared on fork/exec) and this could interfere with various things, e.g. the login grace timer.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic). So this adds an extra "force" argument to the channel cleanup callback to indicate this condition. ok markus dtucker OpenBSD-Commit-ID: 23052707a42bdc62fda2508636e624afd466324b * upstream: tweak channel ctype names These are now used by sshd_config:ChannelTimeouts to specify timeouts by channel type, so force them all to use a similar format without whitespace. ok dtucker markus OpenBSD-Commit-ID: 66834765bb4ae14f96d2bb981ac98a7dae361b65 * upstream: Add channel_set_xtype() This sets an "extended" channel type after channel creation (e.g. "session:subsystem:sftp") that will be used for setting channel inactivity timeouts. ok markus dtucker OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca * upstream: Implement channel inactivity timeouts This adds a sshd_config ChannelTimeouts directive that allows channels that have not seen traffic in a configurable interval to be automatically closed. Different timeouts may be applied to session, X11, agent and TCP forwarding channels. Note: this only affects channels over an opened SSH connection and not the connection itself. Most clients close the connection when their channels go away, with a notable exception being ssh(1) in multiplexing mode. ok markus dtucker OpenBSD-Commit-ID: ae8bba3ed9d9f95ff2e2dc8dcadfa36b48e6c0b8 * unbreak scp on NetBSD 4.x e555d5cad5 effectively increased the default copy buffer size for SFTP transfers.

It's possible to install an OpenSSL in a path not in the system's default library search path. OpenSSH can still use this (eg if you specify an rpath) but the openssl binary there may not work. If one is available on the system path just use that. * Use our own netcat for dynamic-forward test. That way we can be surer about its behaviour rather than trying to second-guess the behaviour of various netcat implementations. * upstream: When OpenSSL is not available, skip parts of percent test that require it.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

And sadly wrong, because of the sing extension risk.. same diff from florian OpenBSD-Commit-ID: 65b9a49a68e22ff3a0ebd593f363e9f22dd73fea * upstream: add a -X option to both scp(1) and sftp(1) to allow control over some SFTP protocol knobs: the copy buffer length and the number of inflight requests, both of which are used during upload/download. Previously these could be controlled in sftp(1) using the -b/-R options. This makes them available in both SFTP protocol clients using the same option character sequence. ok dtucker@ OpenBSD-Commit-ID: 27502bffc589776f5da1f31df8cb51abe9a15f1c * upstream: add -X to usage(); OpenBSD-Commit-ID: 1bdc3df7de11d766587b0428318336dbffe4a9d0 * upstream: Clear signal mask early in main(); sshd may have been started with one or more signals masked (sigprocmask(2) is not cleared on fork/exec) and this could interfere with various things, e.g. the login grace timer.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic). So this adds an extra "force" argument to the channel cleanup callback to indicate this condition. ok markus dtucker OpenBSD-Commit-ID: 23052707a42bdc62fda2508636e624afd466324b * upstream: tweak channel ctype names These are now used by sshd_config:ChannelTimeouts to specify timeouts by channel type, so force them all to use a similar format without whitespace. ok dtucker markus OpenBSD-Commit-ID: 66834765bb4ae14f96d2bb981ac98a7dae361b65 * upstream: Add channel_set_xtype() This sets an "extended" channel type after channel creation (e.g. "session:subsystem:sftp") that will be used for setting channel inactivity timeouts. ok markus dtucker OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca * upstream: Implement channel inactivity timeouts This adds a sshd_config ChannelTimeouts directive that allows channels that have not seen traffic in a configurable interval to be automatically closed. Different timeouts may be applied to session, X11, agent and TCP forwarding channels. Note: this only affects channels over an opened SSH connection and not the connection itself. Most clients close the connection when their channels go away, with a notable exception being ssh(1) in multiplexing mode. ok markus dtucker OpenBSD-Commit-ID: ae8bba3ed9d9f95ff2e2dc8dcadfa36b48e6c0b8 * unbreak scp on NetBSD 4.x e555d5cad5 effectively increased the default copy buffer size for SFTP transfers.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0 * upstream: Move scp path setting to a helper function. The previous commit to add scp to the test sshd's path causes the t-envpass test to fail when the test scp is given using a fully qualified path. Put this in a helper function and only call it from the scp tests. OpenBSD-Regress-ID: 7533dc1c4265c1de716abb062957994195b36df4 * Retry package installation 3 times. When setting up the CI environment, retry package installation 3 times before going up.

Valgrind slows things down so much that the timeout test fails. Skip this test until we figure out if we can make it work. * upstream: tweak previous; ok djm OpenBSD-Commit-ID: df71ce4180c58202dfdc1d92626cfe900b91b7c3 * upstream: Create and install sshd random relink kit. ../Makefile.inc and Makfile are concatenated for reuse, which hopefully won't be too fragile, we'll see if we need a different approach. The resulting sshd binary is tested with the new sshd -V option before installation. As the binary layout is now semi-unknown (meaning relative, fixed, and gadget offsets are not precisely known), change the filesystem permissions to 511 to prevent what I call "logged in BROP".

From Pedro Martelletto via GHPR#388 OpenBSD-Commit-ID: 007eb7e387d27cf3029ab06b88224e03eca62ccd * Remove arc4random_uniform from arc4random.c This was previously moved into its own file (matching OpenBSD) which prematurely committed in commit 73541f2. * Move OPENBSD ORIGINAL marker. Putting this after the copyright statement (which doesn't change) instead of before the version identifier (which does) prevents merge conflicts when resyncing changes. * Resync arc4random with OpenBSD.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic).

Avoids PIN prompts for FIDO tokens that don't require them; part of GHPR#302 OpenBSD-Commit-ID: 4f752aaf9f2e7c28bcaaf3d4f8fc290131bd038e * Install Cygwin packages based on OS not config. * initial list of allowed signers * upstream: whitespace OpenBSD-Commit-ID: d297e4387935d4aef091c5e9432578c2e513f538 * upstream: whitespace OpenBSD-Commit-ID: a5d015efbfd228dc598ffdef612d2da3a579e5d8 * Add cygwin-release test target. This also moves the cygwin package install from the workflow file to setup_ci.sh so that we can install different sets of Cygwin packages for different test configs. * Add Windows 2022 test targets. * Add libcrypt-devel to cygwin-release deps.

Putting this after the copyright statement (which doesn't change) instead of before the version identifier (which does) prevents merge conflicts when resyncing changes. * Resync arc4random with OpenBSD.

Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic). So this adds an extra "force" argument to the channel cleanup callback to indicate this condition. ok markus dtucker OpenBSD-Commit-ID: 23052707a42bdc62fda2508636e624afd466324b * upstream: tweak channel ctype names These are now used by sshd_config:ChannelTimeouts to specify timeouts by channel type, so force them all to use a similar format without whitespace. ok dtucker markus OpenBSD-Commit-ID: 66834765bb4ae14f96d2bb981ac98a7dae361b65 * upstream: Add channel_set_xtype() This sets an "extended" channel type after channel creation (e.g. "session:subsystem:sftp") that will be used for setting channel inactivity timeouts. ok markus dtucker OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca * upstream: Implement channel inactivity timeouts This adds a sshd_config ChannelTimeouts directive that allows channels that have not seen traffic in a configurable interval to be automatically closed.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

This ensures that the tests don't fail due to StrictMode checks. * Use sudo when resetting perms on directories. * Add tests for LibreSSL 3.7.0 and OpenSSL 1.1.1s. * Simply handling of SSH_CONNECTION PAM env var. Prompted by bz#3508: there's no need to cache the value of sshpam_conninfo so remove the global. While there, add check of return value from pam_putenv. ok djm@ * upstream: The idiomatic way of coping with signed char vs unsigned char (which did not come from stdio read functions) in the presence of ctype macros, is to always cast to (unsigned char). casting to (int) for a "macro" which is documented to take int, is weird. And sadly wrong, because of the sing extension risk.. same diff from florian OpenBSD-Commit-ID: 65b9a49a68e22ff3a0ebd593f363e9f22dd73fea * upstream: add a -X option to both scp(1) and sftp(1) to allow control over some SFTP protocol knobs: the copy buffer length and the number of inflight requests, both of which are used during upload/download. Previously these could be controlled in sftp(1) using the -b/-R options. This makes them available in both SFTP protocol clients using the same option character sequence. ok dtucker@ OpenBSD-Commit-ID: 27502bffc589776f5da1f31df8cb51abe9a15f1c * upstream: add -X to usage(); OpenBSD-Commit-ID: 1bdc3df7de11d766587b0428318336dbffe4a9d0 * upstream: Clear signal mask early in main(); sshd may have been started with one or more signals masked (sigprocmask(2) is not cleared on fork/exec) and this could interfere with various things, e.g. the login grace timer. Execution environments that fail to clear the signal mask before running sshd are clearly broken, but apparently they do exist.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic). So this adds an extra "force" argument to the channel cleanup callback to indicate this condition. ok markus dtucker OpenBSD-Commit-ID: 23052707a42bdc62fda2508636e624afd466324b * upstream: tweak channel ctype names These are now used by sshd_config:ChannelTimeouts to specify timeouts by channel type, so force them all to use a similar format without whitespace. ok dtucker markus OpenBSD-Commit-ID: 66834765bb4ae14f96d2bb981ac98a7dae361b65 * upstream: Add channel_set_xtype() This sets an "extended" channel type after channel creation (e.g. "session:subsystem:sftp") that will be used for setting channel inactivity timeouts. ok markus dtucker OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca * upstream: Implement channel inactivity timeouts This adds a sshd_config ChannelTimeouts directive that allows channels that have not seen traffic in a configurable interval to be automatically closed. Different timeouts may be applied to session, X11, agent and TCP forwarding channels. Note: this only affects channels over an opened SSH connection and not the connection itself. Most clients close the connection when their channels go away, with a notable exception being ssh(1) in multiplexing mode. ok markus dtucker OpenBSD-Commit-ID: ae8bba3ed9d9f95ff2e2dc8dcadfa36b48e6c0b8 * unbreak scp on NetBSD 4.x e555d5cad5 effectively increased the default copy buffer size for SFTP transfers.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0 * upstream: Move scp path setting to a helper function. The previous commit to add scp to the test sshd's path causes the t-envpass test to fail when the test scp is given using a fully qualified path. Put this in a helper function and only call it from the scp tests. OpenBSD-Regress-ID: 7533dc1c4265c1de716abb062957994195b36df4 * Retry package installation 3 times.

The resulting sshd binary is tested with the new sshd -V option before installation. As the binary layout is now semi-unknown (meaning relative, fixed, and gadget offsets are not precisely known), change the filesystem permissions to 511 to prevent what I call "logged in BROP".

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic).

Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic).

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

This ensures that the tests don't fail due to StrictMode checks. * Use sudo when resetting perms on directories. * Add tests for LibreSSL 3.7.0 and OpenSSL 1.1.1s. * Simply handling of SSH_CONNECTION PAM env var. Prompted by bz#3508: there's no need to cache the value of sshpam_conninfo so remove the global. While there, add check of return value from pam_putenv. ok djm@ * upstream: The idiomatic way of coping with signed char vs unsigned char (which did not come from stdio read functions) in the presence of ctype macros, is to always cast to (unsigned char). casting to (int) for a "macro" which is documented to take int, is weird. And sadly wrong, because of the sing extension risk.. same diff from florian OpenBSD-Commit-ID: 65b9a49a68e22ff3a0ebd593f363e9f22dd73fea * upstream: add a -X option to both scp(1) and sftp(1) to allow control over some SFTP protocol knobs: the copy buffer length and the number of inflight requests, both of which are used during upload/download. Previously these could be controlled in sftp(1) using the -b/-R options. This makes them available in both SFTP protocol clients using the same option character sequence. ok dtucker@ OpenBSD-Commit-ID: 27502bffc589776f5da1f31df8cb51abe9a15f1c * upstream: add -X to usage(); OpenBSD-Commit-ID: 1bdc3df7de11d766587b0428318336dbffe4a9d0 * upstream: Clear signal mask early in main(); sshd may have been started with one or more signals masked (sigprocmask(2) is not cleared on fork/exec) and this could interfere with various things, e.g. the login grace timer. Execution environments that fail to clear the signal mask before running sshd are clearly broken, but apparently they do exist.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic). So this adds an extra "force" argument to the channel cleanup callback to indicate this condition. ok markus dtucker OpenBSD-Commit-ID: 23052707a42bdc62fda2508636e624afd466324b * upstream: tweak channel ctype names These are now used by sshd_config:ChannelTimeouts to specify timeouts by channel type, so force them all to use a similar format without whitespace. ok dtucker markus OpenBSD-Commit-ID: 66834765bb4ae14f96d2bb981ac98a7dae361b65 * upstream: Add channel_set_xtype() This sets an "extended" channel type after channel creation (e.g. "session:subsystem:sftp") that will be used for setting channel inactivity timeouts. ok markus dtucker OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca * upstream: Implement channel inactivity timeouts This adds a sshd_config ChannelTimeouts directive that allows channels that have not seen traffic in a configurable interval to be automatically closed. Different timeouts may be applied to session, X11, agent and TCP forwarding channels. Note: this only affects channels over an opened SSH connection and not the connection itself. Most clients close the connection when their channels go away, with a notable exception being ssh(1) in multiplexing mode. ok markus dtucker OpenBSD-Commit-ID: ae8bba3ed9d9f95ff2e2dc8dcadfa36b48e6c0b8 * unbreak scp on NetBSD 4.x e555d5cad5 effectively increased the default copy buffer size for SFTP transfers.

An upcoming change renders this obsolete by adding scp's path to the test sshd's PATH, and removing this first will make the subsequent sync easier. * upstream: Add scp's path to test sshd's PATH.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

It's possible to install an OpenSSL in a path not in the system's default library search path. OpenSSH can still use this (eg if you specify an rpath) but the openssl binary there may not work.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0 * upstream: Move scp path setting to a helper function. The previous commit to add scp to the test sshd's path causes the t-envpass test to fail when the test scp is given using a fully qualified path. Put this in a helper function and only call it from the scp tests. OpenBSD-Regress-ID: 7533dc1c4265c1de716abb062957994195b36df4 * Retry package installation 3 times.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic).

Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic). So this adds an extra "force" argument to the channel cleanup callback to indicate this condition. ok markus dtucker OpenBSD-Commit-ID: 23052707a42bdc62fda2508636e624afd466324b * upstream: tweak channel ctype names These are now used by sshd_config:ChannelTimeouts to specify timeouts by channel type, so force them all to use a similar format without whitespace. ok dtucker markus OpenBSD-Commit-ID: 66834765bb4ae14f96d2bb981ac98a7dae361b65 * upstream: Add channel_set_xtype() This sets an "extended" channel type after channel creation (e.g. "session:subsystem:sftp") that will be used for setting channel inactivity timeouts. ok markus dtucker OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca * upstream: Implement channel inactivity timeouts This adds a sshd_config ChannelTimeouts directive that allows channels that have not seen traffic in a configurable interval to be automatically closed.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

This ensures that the tests don't fail due to StrictMode checks. * Use sudo when resetting perms on directories. * Add tests for LibreSSL 3.7.0 and OpenSSL 1.1.1s. * Simply handling of SSH_CONNECTION PAM env var. Prompted by bz#3508: there's no need to cache the value of sshpam_conninfo so remove the global. While there, add check of return value from pam_putenv. ok djm@ * upstream: The idiomatic way of coping with signed char vs unsigned char (which did not come from stdio read functions) in the presence of ctype macros, is to always cast to (unsigned char). casting to (int) for a "macro" which is documented to take int, is weird. And sadly wrong, because of the sing extension risk.. same diff from florian OpenBSD-Commit-ID: 65b9a49a68e22ff3a0ebd593f363e9f22dd73fea * upstream: add a -X option to both scp(1) and sftp(1) to allow control over some SFTP protocol knobs: the copy buffer length and the number of inflight requests, both of which are used during upload/download. Previously these could be controlled in sftp(1) using the -b/-R options. This makes them available in both SFTP protocol clients using the same option character sequence. ok dtucker@ OpenBSD-Commit-ID: 27502bffc589776f5da1f31df8cb51abe9a15f1c * upstream: add -X to usage(); OpenBSD-Commit-ID: 1bdc3df7de11d766587b0428318336dbffe4a9d0 * upstream: Clear signal mask early in main(); sshd may have been started with one or more signals masked (sigprocmask(2) is not cleared on fork/exec) and this could interfere with various things, e.g. the login grace timer. Execution environments that fail to clear the signal mask before running sshd are clearly broken, but apparently they do exist.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic). So this adds an extra "force" argument to the channel cleanup callback to indicate this condition. ok markus dtucker OpenBSD-Commit-ID: 23052707a42bdc62fda2508636e624afd466324b * upstream: tweak channel ctype names These are now used by sshd_config:ChannelTimeouts to specify timeouts by channel type, so force them all to use a similar format without whitespace. ok dtucker markus OpenBSD-Commit-ID: 66834765bb4ae14f96d2bb981ac98a7dae361b65 * upstream: Add channel_set_xtype() This sets an "extended" channel type after channel creation (e.g. "session:subsystem:sftp") that will be used for setting channel inactivity timeouts. ok markus dtucker OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca * upstream: Implement channel inactivity timeouts This adds a sshd_config ChannelTimeouts directive that allows channels that have not seen traffic in a configurable interval to be automatically closed. Different timeouts may be applied to session, X11, agent and TCP forwarding channels. Note: this only affects channels over an opened SSH connection and not the connection itself. Most clients close the connection when their channels go away, with a notable exception being ssh(1) in multiplexing mode. ok markus dtucker OpenBSD-Commit-ID: ae8bba3ed9d9f95ff2e2dc8dcadfa36b48e6c0b8 * unbreak scp on NetBSD 4.x e555d5cad5 effectively increased the default copy buffer size for SFTP transfers.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0 * upstream: Move scp path setting to a helper function. The previous commit to add scp to the test sshd's path causes the t-envpass test to fail when the test scp is given using a fully qualified path. Put this in a helper function and only call it from the scp tests. OpenBSD-Regress-ID: 7533dc1c4265c1de716abb062957994195b36df4 * Retry package installation 3 times.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic).

This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic). So this adds an extra "force" argument to the channel cleanup callback to indicate this condition. ok markus dtucker OpenBSD-Commit-ID: 23052707a42bdc62fda2508636e624afd466324b * upstream: tweak channel ctype names These are now used by sshd_config:ChannelTimeouts to specify timeouts by channel type, so force them all to use a similar format without whitespace. ok dtucker markus OpenBSD-Commit-ID: 66834765bb4ae14f96d2bb981ac98a7dae361b65 * upstream: Add channel_set_xtype() This sets an "extended" channel type after channel creation (e.g. "session:subsystem:sftp") that will be used for setting channel inactivity timeouts. ok markus dtucker OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca * upstream: Implement channel inactivity timeouts This adds a sshd_config ChannelTimeouts directive that allows channels that have not seen traffic in a configurable interval to be automatically closed.

On some very old platforms, sys/stat.h needs sys/types.h, however autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the opposite order, which in combination with modern autoconf's "present but cannot be compiled" behaviour causes it to not be detected. * Add fallback for old platforms w/out MAP_ANON. * Remove explicit "default" test config argument. Not specifying the test config implicitly selects default args. * Remove unused self-hosted test targets. * Rename "os" in matrix to "target". This is in preparation to distinguish this from the host that the runner runs on in case where they are separate (eg VMs). * Add "libvirt" label to dfly30. * Make "config" in matrix singular and pass in env. This will allow the startup scripts to adapt their behaviour based on the type and config. * Run vmstartup from temp dir. This will allow us to create ephemeral disk images per-runner. * Rework how selfhosted tests interact with runners. Previously there was one runner per test target (mostly VMs). This had a few limitations: - multiple tests that ran on the same target (eg multiple build configs) were serialized on availability or that runner. - it needed manual balancing of VMs over host machines. To address this, make VMs that use ephemeral disks (ie most of them) all use a pool of runners with the "libvirt" label. This requires that we distinguish between "host" and "target" for those. Native runners and VMs with persistent disks (eg the constantly-updated snapshot ones) specify the same host and target. This should improve test throughput. * Skip unit tests on slow riscv64 hardware. * Use -fzero-call-used-regs=used on clang 15. clang 15 seems to have a problem with -fzero-call-used-reg=all which causes spurious "incorrect signature" failures with ED25519. On those versions, use -fzero-call-used-regs=used instead. (We may add exceptions later if specific versions prove to be OK). Also move the GCC version check to match.

This ensures that the tests don't fail due to StrictMode checks. * Use sudo when resetting perms on directories. * Add tests for LibreSSL 3.7.0 and OpenSSL 1.1.1s. * Simply handling of SSH_CONNECTION PAM env var. Prompted by bz#3508: there's no need to cache the value of sshpam_conninfo so remove the global. While there, add check of return value from pam_putenv. ok djm@ * upstream: The idiomatic way of coping with signed char vs unsigned char (which did not come from stdio read functions) in the presence of ctype macros, is to always cast to (unsigned char). casting to (int) for a "macro" which is documented to take int, is weird. And sadly wrong, because of the sing extension risk.. same diff from florian OpenBSD-Commit-ID: 65b9a49a68e22ff3a0ebd593f363e9f22dd73fea * upstream: add a -X option to both scp(1) and sftp(1) to allow control over some SFTP protocol knobs: the copy buffer length and the number of inflight requests, both of which are used during upload/download. Previously these could be controlled in sftp(1) using the -b/-R options. This makes them available in both SFTP protocol clients using the same option character sequence. ok dtucker@ OpenBSD-Commit-ID: 27502bffc589776f5da1f31df8cb51abe9a15f1c * upstream: add -X to usage(); OpenBSD-Commit-ID: 1bdc3df7de11d766587b0428318336dbffe4a9d0 * upstream: Clear signal mask early in main(); sshd may have been started with one or more signals masked (sigprocmask(2) is not cleared on fork/exec) and this could interfere with various things, e.g. the login grace timer. Execution environments that fail to clear the signal mask before running sshd are clearly broken, but apparently they do exist. Reported by Sreedhar Balasubramanian; ok dtucker@ OpenBSD-Commit-ID: 77078c0b1c53c780269fc0c416f121d05e3010ae * upstream: Mention that scp uses the SFTP protocol and remove reference to legacy flag.

Previously the detach function was only ever called during channel garbage collection, but there was no way to signal the user of a channel (e.g. session.c) that its channel was being closed deliberately (vs. by the usual state-machine logic). So this adds an extra "force" argument to the channel cleanup callback to indicate this condition. ok markus dtucker OpenBSD-Commit-ID: 23052707a42bdc62fda2508636e624afd466324b * upstream: tweak channel ctype names These are now used by sshd_config:ChannelTimeouts to specify timeouts by channel type, so force them all to use a similar format without whitespace. ok dtucker markus OpenBSD-Commit-ID: 66834765bb4ae14f96d2bb981ac98a7dae361b65 * upstream: Add channel_set_xtype() This sets an "extended" channel type after channel creation (e.g. "session:subsystem:sftp") that will be used for setting channel inactivity timeouts. ok markus dtucker OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca * upstream: Implement channel inactivity timeouts This adds a sshd_config ChannelTimeouts directive that allows channels that have not seen traffic in a configurable interval to be automatically closed. Different timeouts may be applied to session, X11, agent and TCP forwarding channels. Note: this only affects channels over an opened SSH connection and not the connection itself. Most clients close the connection when their channels go away, with a notable exception being ssh(1) in multiplexing mode. ok markus dtucker OpenBSD-Commit-ID: ae8bba3ed9d9f95ff2e2dc8dcadfa36b48e6c0b8 * unbreak scp on NetBSD 4.x e555d5cad5 effectively increased the default copy buffer size for SFTP transfers. This caused NetBSD 4.x to hang during the "copy local file to remote file in place" scp.sh regression test. This puts back the original 32KB copy buffer size until we can properly figure out why. lots of debugging assistance from dtucker@ * upstream: Copy bytes from the_banana[] rather than banana() Fixes test failure due to segfault seen on arm64 with xonly snap. ok djm OpenBSD-Regress-ID: 86e2aa4bbd1dff1bc4ebb2969c0d6474485be046 * upstream: unit tests for misc.c:ptimeout_* API OpenBSD-Regress-ID: 01f8fb12d08e5aaadd4bd4e71f456b6588be9a94 * upstream: fix typo in verbose logging OpenBSD-Regress-ID: 0497cdb66e003b2f50ed77291a9104fba2e017e9 * upstream: regression test for ChannelTimeout OpenBSD-Regress-ID: 280bfbefcfa415428ad744e43f69a8dede8ad685 * upstream: Save debug logs from ssh for debugging purposes.

It's possible to install an OpenSSL in a path not in the system's default library search path. OpenSSH can still use this (eg if you specify an rpath) but the openssl binary there may not work. If one is available on the system path just use that. * Use our own netcat for dynamic-forward test. That way we can be surer about its behaviour rather than trying to second-guess the behaviour of various netcat implementations. * upstream: When OpenSSL is not available, skip parts of percent test that require it. Based on github pr#368 from ren mingshuai. OpenBSD-Regress-ID: 49a375b2cf61ccb95b52e75e2e025cd10988ebb2 * don't test IPv6 addresses if platform lacks support * Skip dynamic-forward test on minix3.

Previously the test would not run at all since it also doesn't have netcat, but now we use our own netcat it tries and fails. * try to improve logging for dynamic-forward test previously the logs from the ssh used to exercise the forwarding channel would clobber the logs from the ssh actually doing the forwarding * upstream: tweak previous; ok djm OpenBSD-Commit-ID: 229c493452766d70a78b0f02f6ff9894f9028858 * upstream: Switch scp from using pipes to a socketpair for communication with it's ssh sub-processes. We no longer need to reserve two descriptors to ensure that we don't end up using fd 0-2 unexpectedly, that is handled by sanitise_stdfd() in main(). Based on an original diff from djm@. OK deraadt@ djm@ OpenBSD-Commit-ID: b80c372faac462471e955ddeab9480d668a2e48d * add back use of pipes in scp.c under USE_PIPES This matches sftp.c which prefers socketpair but uses pipes on some older platforms. * remove buffer len workaround for NetBSD 4.x Switching to from pipes to a socketpair for communicating with the ssh process avoids the (kernel bug?) problem. * upstream: rewrite this test to use a multiplexed ssh session so we can control its lifecycle without risk of race conditions; fixes some of the Github integration tests for openssh-portable OpenBSD-Regress-ID: 5451cad59ba0d43ae9eeda48ec80f54405fee969 * upstream: remove whitespace at EOL from code extracted from SUPERCOP OpenBSD-Commit-ID: 1ec524ff2fbb9387d731601437c82008f35a60f4 * upstream: ignore bogus upload/download buffer lengths in the limits extension OpenBSD-Commit-ID: c5b023e0954693ba9a5376e4280c739b5db575f8 * upstream: clamp the minimum buffer lengths and number of inflight requests too OpenBSD-Commit-ID: c4965f62fa0ba850940fd66ae3f60cf516bbcd56 * upstream: avoid printf("%s", NULL) if using ssh -oUserKnownHostsFile=none and a hostkey in one of the system known hosts file changes; ok dtucker@ OpenBSD-Commit-ID: 7ca87614bfc6da491315536a7f2301434a9fe614 * upstream: Add a "Host" line to the output of ssh -G showing the original host arg. Inspired by patch from vincent at bernat.ch via bz#3343, ok djm@ OpenBSD-Commit-ID: 59c0f60a222113a44d0650cd394376e3beecc883 * Remove skipping test when scp not in path. An upcoming change renders this obsolete by adding scp's path to the test sshd's PATH, and removing this first will make the subsequent sync easier. * upstream: Add scp's path to test sshd's PATH. If the scp we're testing is fully qualified (eg it's not in the system PATH) then add its path to the under-test sshd's PATH so we can find it. Prompted by bz#3518. OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0 * upstream: Move scp path setting to a helper function. The previous commit to add scp to the test sshd's path causes the t-envpass test to fail when the test scp is given using a fully qualified path. Put this in a helper function and only call it from the scp tests. OpenBSD-Regress-ID: 7533dc1c4265c1de716abb062957994195b36df4 * Retry package installation 3 times. When setting up the CI environment, retry package installation 3 times before going up.

The resulting sshd binary is tested with the new sshd -V option before installation. As the binary layout is now semi-unknown (meaning relative, fixed, and gadget offsets are not precisely known), change the filesystem permissions to 511 to prevent what I call "logged in BROP".
