* upstream: fix poll() spin when a channel's output fd closes without

data in the channel buffer. Introduce more exact packing of channel fds into
the pollfd array. fixes bz3405 and bz3411; ok deraadt@ markus@

OpenBSD-Commit-ID: 06740737849c9047785622ad5d472cb6a3907d10

* upstream: select post-quantum KEX

sntrup761x25519-sha512@openssh.com as the default; ok markus@

OpenBSD-Commit-ID: f02d99cbfce22dffec2e2ab1b60905fbddf48fb9

* upstream: add support for the "corp-data" protocol extension to

allow server-side copies to be performed without having to go via the client.
Patch by Mike Frysinger, ok dtucker@

OpenBSD-Commit-ID: 00aa510940fedd66dab1843b58682de4eb7156d5

* upstream: add a sftp client "cp" command that supports server-side

copying of files. Useful for this task and for testing the copy-data
extension. Patch from Mike Frysinger; ok dtucker@

* depend

* Skip slow tests on (very) slow test targets.

* Set Makefile SHELL as determined by configure.

This should improve compatibility for users with non-POSIX shells.  If
using Makefile.in directly (eg make -f Makefile.in distprep) then SHELL
will need to be specified on the command line (along with MANFMT in that
particular case).  ok djm@

* Use bash or ksh if available for SH in Makefile.

* Increase test timeout to allow slow VMs to finish

* Only run regression tests on slow VMs.

* Only return events from ppoll that were requested.

If the underlying system's select() returns bits that were not in the
request set, our ppoll() implementation can return revents for events
not requested, which can apparently cause a hang.  Only return revents
for activity in the requested event set.  bz#3416, analysis and fix by
yaroslav.kuzmin at vmssoftware com, ok djm@

* Specify TEST_SHELL=bash on AIX.

The system shells cause the agent-restrict test to fail due to some
quoting so explicitly specify bash until we can get configure to
autmatically work around that.

* Disable security key on fbsd6 test host.

* upstream: man pages: add missing commas between subordinate and

main clauses

jmc@ dislikes a comma before "then" in a conditional, so leave those
untouched.

OpenBSD-Commit-ID: 0dfb461188f4513ec024c1534da8c1ce14c20b64

* update version numbers for release

* update build-aux files to match autoconf-2.71

i.e. config.guess, config.sub and install-sh

* Revert "update build-aux files to match autoconf-2.71"

This reverts commit 0a8ca39fac6ad19096b6c263436f8b2dd51606f2.

It turns out that the checked-in copies of these files are actually newer
than autoconf-2.71's copies, so this was effectively a downgrade.
Spotted by Bo Anderson via github

* upstream: two defensive changes from Tobias Stoeckmann via GHPR287

enforce stricter invarient for sshbuf_set_parent() - never allow
a buffer to have a previously-set parent changed.

In sshbuf_reset(), if the reallocation fails, then zero the entire
buffer and not the (potentially smaller) default initial alloc size.

* upstream: Simplify forward-control test.

Since we no longer need to support SSH1 we don't need to run shell
commands on the other end of the connection and can use ssh -N instead.
This also makes the test less racy.

OpenBSD-Regress-ID: 32e94ce272820cc398f30b848b2b0f080d10302c

* Cache timezone data in capsicum sandbox.

From emaste at freebsd.org, originally part of FreeBSD commit r339216
/ fc3c19a9 with autoconf bits added by me.

* Include stdlib.h for free() prototype.

... which is used inside the CUSTOM_SYS_AUTH_GET_LASTLOGIN_MSG block.

* Update OpenSSL and LibreSSL versions in tests.

* Add debian-riscv64 test target.

* upstream: Avoid an unnecessary xstrdup in rm_env() when matching

patterns. Since match_pattern() doesn't modify its arguments (they are
const), there is no need to make an extra copy of the strings in
options->send_env. From Martin Vahlensieck

stdlib.h for malloc(3) and stdint.h for SIZE_MAX. Unlike the other xmss
files, ssh-xmss.c does not include xmss_commons.h so ssh-xmss.c must include
those headers itself. From Martin Vahlensieck

works. The wording came mostly from the 8.2 OpenSSH release notes, addapted
to fit the man page. Then move the -O bits into the new section as is already
done for CERTIFICATES and MODULI GENERATION. Finally we can explain the
trade-offs of resident keys. While here, consistently refer to the FIDO
thingies as "FIDO authenticators", not "FIDO tokens".

* Add ubsan minimal testcase on OpenBSD.

As suggested by djm@.

* Note that, for now, we need variadic macros.

* Also retest OpenBSD upstream on .yml changes.

* upstream: When performing operations that glob(3) a remote path, ensure

that the implicit working directory used to construct that path escapes
glob(3) characters.

This prevents glob characters from being processed in places they
shouldn't, e.g. "cd /tmp/a*/", "get *.txt" should have the get operation
treat the path "/tmp/a*" literally and not attempt to expand it.

* Test against openssl-3.0.5.

* Move unset to before we set anything.

* Refuse to use OpenSSL 3.0.4 due to potential RCE.

OpenSSL has a potential RCE in its RSA implementation (CVE-2022-2274)
so refuse to use that specific version.

* Capture stderr output from configure.

* Only refuse to use OpenSSL 3.0.4 on x86_64.

The potential RCE only impacts x86_64, so only refuse to use it if we're
targetting a potentially impacted architecture.  ok djm@

* Remove special casing of crypt().

Configure goes to some lengths to pick crypt() from either libcrypt
or OpenSSL's libcrypto because they can more or less featureful (eg
supporting md5-style passwords).

OpenSSL removed its crypt() interface in 2002:
https://github.com/openssl/openssl/commit/69deec58 so these hijinks
should no longer be necessary.  This also only links sshd with libcrypt
which is the only thing that needs it.  ok djm@

* Clarify README.md text.

Clarify the text about the implications of building without OpenSSL, and
prefix the "configure --help" example command with a "./" so it's likely
to work as-is in more shells.  From bz#3461.

* Split README.platform into its own line.

README.platform has general platform-specific information, having it
following text about FIDO2 on the same line could imply that it only
has information about FIDO2.

* Return ERANGE from getcwd() if buffer size is 1.

If getcwd() is supplied a buffer size of exactly 1 and a path of "/", it
could result in a nul byte being written out of array bounds.  POSIX says
it should return ERANGE if the path will not fit in the available buffer
(with terminating nul). 1 byte cannot fit any possible path with its nul,
so immediately return ERANGE in that case.

OpenSSH never uses getcwd() with this buffer size, and all current
(and even quite old) platforms that we are currently known to work
on have a native getcwd() so this code is not used on those anyway.

* crank SSH_SK_VERSION_MAJOR in sk-dummy.so

scp -3 ends up using the scp that's in the remote path and will fail if
one is not available.  Based on a patch from rapier at psc.edu.

* Convert "have_prog" function into "which".

"which" and its behaviour is not standardized, so convert the existing

existing behaviour.

* Remove workarounds for OpenSSL missing AES-GCM.

We have some compatibility hacks that were added to support OpenSSL
versions that do not support AES GCM mode.  Since that time, however,
the minimum OpenSSL version that we support has moved to 1.0.1 which
*does* have GCM, so this is no longer needed.  ok djm@

* Remove workarounds for OpenSSL missing AES-CTR.

We have some compatibility hacks that were added to support OpenSSL
versions that do not support AES CTR mode.  Since that time, however,
the minimum OpenSSL version that we support has moved to 1.0.1 which
*does* have CTR, so this is no longer needed.  ok djm@

* Do not link scp, sftp and sftp-server w/ zlib.

Some of our binaries (eg sftp, sftp-server, scp) do not interact with
the channels code and thus do use libraries such as zlib and libcrypto
although they are linked with them.  This adds a CHANNELLIBS and starts
by moving zlib into it, which means the aformentioned binaries are no
longer linked against zlib.  ok djm@

* Group libcrypto and PRNGD checks together.

They're related more than the libcrypt or libiaf checks which are
currently between them.  ok djm@

* Remove seed_rng calls from scp, sftp, sftp-server.

These binaries don't use OpenSSL's random functions.  The next step
will be to stop linking them against libcrypto.  ok djm@

* Move libcrypto into CHANNELLIBS.

This will result in sftp, sftp-server and scp no longer being linked
against libcrypto.  ok djm@

* Move stale-configure check as early as possible.

We added a check in Makefile to catch the case where configure needs to
be rebuilt, however this did not happen until a build was attempted in
which case all of the work done by configure was wasted.  Move this check
 to the start of configure to catch it as early as possible.  ok djm@

* check_sk_options: add temporary WinHello workaround

Up to libfido 1.10.0, WinHello advertises "clientPin" rather

* sk_sign: set FIDO2 uv attribute explicitely for WinHello

WinHello via libfido2 performs user verification by default.
However, if we stick to that, there's no way to differentiate
between keys created with or without "-O  verify-required".
Set FIDO2 uv attribute explicitely to FIDO_OPT_FALSE, then check
if user verification has been requested.

* Give unused param a name.

Fixes builds on platforms that do have fido2 but don't have
fido_dev_is_winhello.

* Actually put HAVE_STDINT_H around the stdint.h.

* Rename our getentropy to prevent possible loops.

Since arc4random seeds from getentropy, and we use OpenSSL for that
if enabled, there's the possibility that if we build on a system that
does not have getentropy then run on a system that does have it, then
OpenSSL could end up calling our getentropy and getting stuck in a loop.

* Test hostbased auth on github runners.

* Fix conditional for running hostbased tests.

* upstream: allow certificate validity intervals, sshsig verification

times and authorized_keys expiry-time options to accept dates in the UTC time
zone in addition to the default of interpreting them in the system time zone.
YYYYMMDD and YYMMDDHHMM[SS] dates/times will be interpreted as UTC if
suffixed with a 'Z' character.

Also allow certificate validity intervals to be specified in raw
seconds-since-epoch as hex value, e.g. -V 0x1234:0x4567890. This
is intended for use by regress tests and other tools that call
ssh-keygen as part of a CA workflow.

Add support to the sftp-server for the home-directory extension defined

There are commands (e.g. "get" or "put") that accept two

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.

9b8ad93824 upstream: support for user-verified FIDO keys
FIDO2 supports a notion of "user verification" where the user is
required to demonstrate their identity to the token before particular
operations (e.g. signing). Typically this is done by authenticating
themselves using a PIN that has been set on the token.

This adds support for generating and using user verified keys where
the verification happens via PIN (other options might be added in the
future, but none are in common use now). Practically, this adds
another key generation option "verify-required" that yields a key that
requires a PIN before each authentication.

Allow writing to disk the attestation certificate that is generated by

trustworthy hardware.

Allow passing in a challenge that will be sent to the card during
key enrollment. These are needed to build an attestation workflow
that resists replay attacks.

c312ca077c upstream: Extends the SK API to accept a set of key/value options
for all operations. These are intended to future-proof the API a little by
making it easier to specify additional fields for without having to change
the API version for each.

At present, only two options are defined: one to explicitly specify
the device for an operation (rather than accepting the middleware's
autoselection) and another to specify the FIDO2 username that may
be used when generating a resident key. These new options may be
invoked at key generation time via ssh-keygen -O

This also implements a suggestion from Markus to avoid "int" in favour
of uint32_t for the algorithm argument in the API, to make implementation
of ssh-sk-client/helper a little easier.
