djm@openbsd.org 81c1099d22
upstream: Add a facility to sshd(8) to penalise particular
problematic client behaviours, controlled by two new sshd_config(5) options:
PerSourcePenalties and PerSourcePenaltyExemptList.

When PerSourcePenalties are enabled, sshd(8) will monitor the exit
status of its child pre-auth session processes. Through the exit
status, it can observe situations where the session did not
authenticate as expected. These conditions include when the client
repeatedly attempted authentication unsucessfully (possibly indicating
an attack against one or more accounts, e.g. password guessing), or
when client behaviour caused sshd to crash (possibly indicating
attempts to exploit sshd).

When such a condition is observed, sshd will record a penalty of some
duration (e.g. 30 seconds) against the client's address. If this time
is above a minimum threshold specified by the PerSourcePenalties, then
connections from the client address will be refused (along with any
others in the same PerSourceNetBlockSize CIDR range).

Repeated offenses by the same client address will accrue greater
penalties, up to a configurable maximum. A PerSourcePenaltyExemptList
option allows certain address ranges to be exempt from all penalties.

We hope these options will make it significantly more difficult for
attackers to find accounts with weak/guessable passwords or exploit
bugs in sshd(8) itself.

PerSourcePenalties is off by default, but we expect to enable it
automatically in the near future.

djm@openbsd.org 03e3de416e
upstream: Start the process of splitting sshd into separate
binaries. This step splits sshd into a listener and a session binary. More
splits are planned.

After this changes, the listener binary will validate the configuration,
load the hostkeys, listen on port 22 and manage MaxStartups only. All
session handling will be performed by a new sshd-session binary that the
listener fork+execs.

This reduces the listener process to the minimum necessary and sets us
up for future work on the sshd-session binary.

NB. if you're updating via source, please restart sshd after installing,
otherwise you run the risk of locking yourself out.

upstream: Add keystroke timing obfuscation to the client.
This attempts to hide inter-keystroke timings by sending interactive
traffic at fixed intervals (default: every 20ms) when there is only a
small amount of data being sent. It also sends fake "chaff" keystrokes
for a random interval after the last real keystroke. These are
controlled by a new ssh_config ObscureKeystrokeTiming keyword/

* 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@.

* upstream: sftp: Don't attempt to complete arguments for

non-existent commands

If user entered a non-existent command (e.g. because they made a
typo) there is no point in trying to complete its arguments. Skip
calling complete_match() if that's the case.

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.

* configure.ac: Fix -Wstrict-prototypes

Clang 16 now warns on this and it'll be removed in C23, so let's
just be future proof. It also reduces noise when doing general
Clang 16 porting work (which is a big job as it is).  github PR#355.

* Fix setres*id checks to work with clang-16.

glibc has the prototypes for setresuid and setresgid behind _GNU_SOURCE,

* Avoid assuming layout of fd_set

POSIX doesn't specify the internal layout of the fd_set object, so let's
not assume it is just a bit mask. This increases compatibility with
systems that have a different layout.

The assumption is also worthless as we already refuse to use file
descriptors over FD_SETSIZE anyway. Meaning that the default size of
fd_set is quite sufficient.

OpenSSL 1.1.1 has a bug in its RNG that breaks reexec fallback, so skip

* 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@

* 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.

* upstream: Add channel_force_close()

This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.

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.

This adds a sshd_config ChannelTimeouts directive that allows channels that

Different timeouts may be applied to session, X11, agent and TCP forwarding

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.

* 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: 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

* 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

treat the path "/tmp/a*" literally and not attempt to expand it.

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.

* Remove workarounds for OpenSSL missing AES-GCM.

We have some compatibility hacks that were added to support OpenSSL

* 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

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

* 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@

This will result in sftp, sftp-server and scp no longer being linked

* 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

* 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.

Also allow certificate validity intervals to be specified in raw

* upstream: add a RequiredRSASize for checking RSA key length in

ssh(1). User authentication keys that fall beneath this limit will be
ignored. If a host presents a host key beneath this limit then the connection
will be terminated (unfortunately there are no fallbacks in the protocol for
host authentication).
