The rationale [1] is that C11 6.5.6.9 says:
"""
When two pointers are subtracted, both shall point to elements of the
same array object, or one past the last element of the array object; the
result is the difference of the subscripts of the two array elements.
"""
In these cases the objects are arrays of char so the result is defined,
and we believe that the compiler incorrectly trapping on defined behaviour.
I also found https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63303
("Pointer subtraction is broken when using -fsanitize=undefined") which seems to support this position.

-Subject: [PATCH] Fix potential signed overflow in pointer arithmatic
-
-Pointer arithmatic results in implementation defined signed integer
-type, so that 's - src' in strlcpy and others may trigger signed overflow.
-In case of compilation by gcc or clang with -ftrapv option, the overflow
-would lead to program abort.

Still side effects of the XZ backdoor. The systemd sd-notify patch
was rejected [1] upstream and was chosen a standalone implementation
that does not depend on libsystemd [2].
Racional [1]:
License incompatibility and library bloatedness were the reasons.
Given recent events we're never going to take a dependency on libsystemd,
though we might implement the notification protocol ourselves if it isn't too much work.

Release notes at https://www.openssh.com/txt/release-9.8
Security
========
This release contains fixes for two security problems, one critical
and one minor.
1) Race condition in sshd(8)
A critical vulnerability in sshd(8) was present in Portable OpenSSH
versions between 8.5p1 and 9.7p1 (inclusive) that may allow arbitrary
code execution with root privileges.
Successful exploitation has been demonstrated on 32-bit Linux/glibc
systems with ASLR. Under lab conditions, the attack requires on
average 6-8 hours of continuous connections up to the maximum the
server will accept. Exploitation on 64-bit systems is believed to be
possible but has not been demonstrated at this time. It's likely that
these attacks will be improved upon.
Exploitation on non-glibc systems is conceivable but has not been
examined. Systems that lack ASLR or users of downstream Linux
distributions that have modified OpenSSH to disable per-connection
ASLR re-randomisation (yes - this is a thing, no - we don't
understand why) may potentially have an easier path to exploitation.
OpenBSD is not vulnerable.
We thank the Qualys Security Advisory Team for discovering, reporting
and demonstrating exploitability of this problem, and for providing
detailed feedback on additional mitigation measures.
2) Logic error in ssh(1) ObscureKeystrokeTiming
In OpenSSH version 9.5 through 9.7 (inclusive), when connected to an
OpenSSH server version 9.5 or later, a logic error in the ssh(1)
ObscureKeystrokeTiming feature (on by default) rendered this feature
ineffective - a passive observer could still detect which network
packets contained real keystrokes when the countermeasure was active
because both fake and real keystroke packets were being sent
unconditionally.
This bug was found by Philippos Giavridis and also independently by
Jacky Wei En Kung, Daniel Hugenroth and Alastair Beresford of the
University of Cambridge Computer Lab.
Worse, the unconditional sending of both fake and real keystroke
packets broke another long-standing timing attack mitigation. Since
OpenSSH 2.9.9 sshd(8) has sent fake keystoke echo packets for
traffic received on TTYs in echo-off mode, such as when entering a
password into su(8) or sudo(8). This bug rendered these fake
keystroke echoes ineffective and could allow a passive observer of
a SSH session to once again detect when echo was off and obtain
fairly limited timing information about keystrokes in this situation
(20ms granularity by default).
This additional implication of the bug was identified by Jacky Wei
En Kung, Daniel Hugenroth and Alastair Beresford and we thank them
for their detailed analysis.
This bug does not affect connections when ObscureKeystrokeTiming
was disabled or sessions where no TTY was requested.
Future deprecation notice
=========================
OpenSSH plans to remove support for the DSA signature algorithm in
early 2025. This release disables DSA by default at compile time.
DSA, as specified in the SSHv2 protocol, is inherently weak - being
limited to a 160 bit private key and use of the SHA1 digest. Its
estimated security level is only 80 bits symmetric equivalent.
OpenSSH has disabled DSA keys by default since 2015 but has retained
run-time optional support for them. DSA was the only mandatory-to-
implement algorithm in the SSHv2 RFCs, mostly because alternative
algorithms were encumbered by patents when the SSHv2 protocol was
specified.
This has not been the case for decades at this point and better
algorithms are well supported by all actively-maintained SSH
implementations. We do not consider the costs of maintaining DSA
in OpenSSH to be justified and hope that removing it from OpenSSH
can accelerate its wider deprecation in supporting cryptography
libraries.
This release, and its deactivation of DSA by default at compile-time,
marks the second step in our timeline to finally deprecate DSA. The
final step of removing DSA support entirely is planned for the first
OpenSSH release of 2025.
DSA support may be re-enabled in OpenBSD by setting "DSAKEY=yes"
in Makefile.inc. To enable DSA support in portable OpenSSH, pass
the "--enable-dsa-keys" option to configure.
Potentially-incompatible changes
--------------------------------
* all: as mentioned above, the DSA signature algorithm is now
disabled at compile time.
* sshd(8): the server will now block client addresses that
repeatedly fail authentication, repeatedly connect without ever
completing authentication or that crash the server. See the
discussion of PerSourcePenalties below for more information.
Operators of servers that accept connections from many users, or
servers that accept connections from addresses behind NAT or
proxies may need to consider these settings.
* sshd(8): the server has been split into a listener binary, sshd(8),
and a per-session binary "sshd-session". This allows for a much
smaller listener binary, as it no longer needs to support the SSH
protocol. As part of this work, support for disabling privilege
separation (which previously required code changes to disable) and
disabling re-execution of sshd(8) has been removed. Further
separation of sshd-session into additional, minimal binaries is
planned for the future.
* sshd(8): several log messages have changed. In particular, some
log messages will be tagged with as originating from a process
named "sshd-session" rather than "sshd".
* ssh-keyscan(1): this tool previously emitted comment lines
containing the hostname and SSH protocol banner to standard error.
This release now emits them to standard output, but adds a new
"-q" flag to silence them altogether.
* sshd(8): (portable OpenSSH only) sshd will no longer use argv[0]
as the PAM service name. A new "PAMServiceName" sshd_config(5)
directive allows selecting the service name at runtime. This
defaults to "sshd". bz2101
* (portable OpenSSH only) Automatically-generated files, such as
configure, config.h.in, etc will now be checked in to the portable
OpenSSH git release branch (e.g. V_9_8). This should ensure that
the contents of the signed release branch exactly match the
contents of the signed release tarball.
Changes since OpenSSH 9.7
=========================
This release contains mostly bugfixes.
New features
------------
* sshd(8): as described above, sshd(8) will now penalise client
addresses that, for various reasons, do not successfully complete
authentication. This feature is controlled by a new sshd_config(5)
PerSourcePenalties option and is on by default.
sshd(8) will now identify 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 bugs in 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 configurable threshold, then all
connections from the client address will be refused (along with any
others in the same PerSourceNetBlockSize CIDR range) until the
penalty expire.
Repeated offenses by the same client address will accrue greater
penalties, up to a configurable maximum. Address ranges may be
fully exempted from penalties, e.g. to guarantee access from a set
of trusted management addresses, using the new sshd_config(5)
PerSourcePenaltyExemptList option.
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. This option is enabled by default.
* ssh(8): allow the HostkeyAlgorithms directive to disable the
implicit fallback from certificate host key to plain host keys.
Bugfixes
--------
* misc: fix a number of inaccuracies in the PROTOCOL.*
documentation files. GHPR430 GHPR487
* all: switch to strtonum(3) for more robust integer parsing in most
places.
* ssh(1), sshd(8): correctly restore sigprocmask around ppoll()
* ssh-keysign(8): stricter validation of messaging socket fd GHPR492
* sftp(1): flush stdout after writing "sftp>" prompt when not using
editline. GHPR480
* sftp-server(8): fix home-directory extension implementation, it
previously always returned the current user's home directory
contrary to the spec. GHPR477
* ssh-keyscan(1): do not close stdin to prevent error messages when
stdin is read multiple times. E.g.
echo localhost | ssh-keyscan -f - -f -
* regression tests: fix rekey test that was testing the same KEX
algorithm repeatedly instead of testing all of them. bz3692
* ssh_config(5), sshd_config(5): clarify the KEXAlgorithms directive
documentation, especially around what is supported vs available.
bz3701.
Portability
-----------
* sshd(8): expose SSH_AUTH_INFO_0 always to PAM auth modules
unconditionally. The previous behaviour was to expose it only when
particular authentication methods were in use.
* build: fix OpenSSL ED25519 support detection. An incorrect function
signature in configure.ac previously prevented enabling the recently
added support for ED25519 private keys in PEM PKCS8 format.
* ssh(1), ssh-agent(8): allow the presence of the WAYLAND_DISPLAY
environment variable to enable SSH_ASKPASS, similarly to the X11
DISPLAY environment variable. GHPR479
* build: improve detection of the -fzero-call-used-regs compiler
flag. bz3673.
* build: relax OpenSSL version check to accept all OpenSSL 3.x
versions.
* sshd(8): add support for notifying systemd on server listen and
reload, using a standalone implementation that doesn't depend on
libsystemd. bz2641

+The SSHAGENT_BIN was changed in [1] to SSH_BIN but

My ssh connections are dropping after being connected for a minute or so
same target worked fine from the same host before. I do have
ServerAliveInterval 30
TCPKeepAlive yes
Sometimes folks would suggest the first solution, but it seems to not
have any effect anymore.

> Changes since OpenSSH 9.7
> =========================
>
> This release contains mostly bugfixes.
>
> New features
> ------------
>
> * sshd(8): as described above, sshd(8) will now penalise client
> addresses that, for various reasons, do not successfully complete
> authentication. This feature is controlled by a new sshd_config(5)
> PerSourcePenalties option and is on by default.
>
> sshd(8) will now identify 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 bugs in 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 configurable threshold, then all
> connections from the client address will be refused (along with any
> others in the same PerSourceNetBlockSize CIDR range) until the
> penalty expire.
>
> Repeated offenses by the same client address will accrue greater
> penalties, up to a configurable maximum. Address ranges may be
> fully exempted from penalties, e.g. to guarantee access from a set
> of trusted management addresses, using the new sshd_config(5)
> PerSourcePenaltyExemptList option.
>
> 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. This option is enabled by default.
>
> * ssh(8): allow the HostkeyAlgorithms directive to disable the
> implicit fallback from certificate host key to plain host keys.
>
> Bugfixes
> --------
>
> * misc: fix a number of inaccuracies in the PROTOCOL.*
> documentation files. GHPR430 GHPR487
>
> * all: switch to strtonum(3) for more robust integer parsing in most
> places.
>
> * ssh(1), sshd(8): correctly restore sigprocmask around ppoll()
>
> * ssh-keysign(8): stricter validation of messaging socket fd GHPR492
>
> * sftp(1): flush stdout after writing "sftp>" prompt when not using
> editline. GHPR480
>
> * sftp-server(8): fix home-directory extension implementation, it
> previously always returned the current user's home directory
> contrary to the spec. GHPR477
>
> * ssh-keyscan(1): do not close stdin to prevent error messages when
> stdin is read multiple times. E.g.
> echo localhost | ssh-keyscan -f - -f -
>
> * regression tests: fix rekey test that was testing the same KEX
> algorithm repeatedly instead of testing all of them. bz3692
>
> * ssh_config(5), sshd_config(5): clarify the KEXAlgorithms directive
> documentation, especially around what is supported vs available.
> bz3701.
>
> Portability
> -----------
>
> * sshd(8): expose SSH_AUTH_INFO_0 always to PAM auth modules
> unconditionally. The previous behaviour was to expose it only when
> particular authentication methods were in use.
>
> * build: fix OpenSSL ED25519 support detection. An incorrect function
> signature in configure.ac previously prevented enabling the recently
> added support for ED25519 private keys in PEM PKCS8 format.
>
> * ssh(1), ssh-agent(8): allow the presence of the WAYLAND_DISPLAY
> environment variable to enable SSH_ASKPASS, similarly to the X11
> DISPLAY environment variable. GHPR479
>
> * build: improve detection of the -fzero-call-used-regs compiler
> flag. bz3673.
>
> * build: relax OpenSSL version check to accept all OpenSSL 3.x
> versions.
>
> * sshd(8): add support for notifying systemd on server listen and
> reload, using a standalone implementation that doesn't depend on
> libsystemd. bz2641

I think the problem might be related to the "+Type=notify-reload" change
in sshd@.service. It's in inetd mode so the upstream change about
SYSTEMD_NOTIFY should have nothing to do with it.
I also doubt if the following line should be removed from sshd.service.
-ExecReload=@BASE_BINDIR@/kill -HUP $MAINPID

Qi

Hi Jose,
The changes in the patch have already done an implicit check:
if ((path = getenv("NOTIFY_SOCKET")) == NULL || strlen(path) == 0)
return;
return;
This means if it’s not systemd who starts sshd (notify type starting), then the function ssh_systemd_notify just does nothing.
I looked at the changes in the patch and the codes around it, if I understand it correctly, in case of ‘-i’ option, sshd does not notify systemd. So the ssd@.service<mailto:ssd@.service> should not use the notify type.
Regards,
Qi

ChenQi <Qi.Chen@windriver.com<mailto:Qi.Chen@windriver.com>> escreveu (quarta, 17/07/2024 à(s) 10:25):
I think the problem might be related to the "+Type=notify-reload" change in sshd@.service<mailto:sshd@.service>. It's in inetd mode so the upstream change about SYSTEMD_NOTIFY should have nothing to do with it.
I also doubt if the following line should be removed from sshd.service.
-ExecReload=@BASE_BINDIR@/kill -HUP $MAINPID
Make sense.
Maybe the service changes in the patch need to be conditional on whether or not we are using systemd.
I'm going to try this path a little.
but I am now facing some issues with testimage without the overall openssh patch series.
Jose

Qi

actually I narrowed down my problem of disconnection to this patch in
the series. Earlier I thought it might be related to the openssh
upgrade patch
but reverting that still causes the problem but this patch when
reverted, the problem is gone.
I will jump on this today and try to find the root cause.
The ptest goes well in my local tests but I didn't do anything with testimage.
I'll see if the testimage picks up something.
Thanks for the feedback.

The SYSTEMD_NOTIFY is always enabled in linux regardless of which init
system is in use.
I have finished the tests with sysvinit and everything looks good.
Can't the timeout Khem mention.
I am now building it with the systemd init manager to test.

I had also seen this detail in the service, I will test it with both
services sshd.service and sshd@.service to see the difference.
The sshd.service runs in the foreground with '-D' and without the '-i'.
I wonder if it wouldn't be better to do the same in both (with -D) and thus
notify the systemd in both?
