Migrate to OpenSSL 3.0 in advance of FreeBSD 14.0. OpenSSL 1.1.1 (the
version we were previously using) will be EOL as of 2023-09-11.
Most of the base system has already been updated for a seamless switch
to OpenSSL 3.0. For many components we've added
`-DOPENSSL_API_COMPAT=0x10100000L` to CFLAGS to specify the API version,
which avoids deprecation warnings from OpenSSL 3.0. Changes have also
been made to avoid OpenSSL APIs that were already deprecated in OpenSSL
1.1.1. The process of updating to contemporary APIs can continue after
this merge.
Additional changes are still required for libarchive and Kerberos-
related libraries or tools; workarounds will immediately follow this
commit. Fixes are in progress in the upstream projects and will be
incorporated when those are next updated.
There are some performance regressions in benchmarks (certain tests in
`openssl speed`) and in some OpenSSL consumers in ports (e.g. haproxy).
Investigation will continue for these.
Netflix's testing showed no functional regression and a rather small,
albeit statistically significant, increase in CPU consumption with
OpenSSL 3.0.
Thanks to ngie@ and des@ for updating base system components, to
antoine@ and bofh@ for ports exp-runs and port fixes/workarounds, and to
Netflix and everyone who tested prior to commit or contributed to this
update in other ways.

We changed the CheckHostIP default to "no" years ago. Upstream has now
made the same change, so do not list it as a local change any longer.
I did not just remove the "Modified client-side defaults" section to
avoid having to renumber everything, and we may add a new local change
in the future.

As Coverity reports:
Overwriting tmp in tmp = make_absolute_pwd_glob(tmp, remote_path)
leaks the storage that tmp points to.
Consume the first arg in make_absolute_pwd_glob, and add xstrdup() to
the one case which did not assign to the same variable that was passed
in. With this change make_absolute() and make_absolute_pwd_glob() have
the same semantics with respect to freeing the input string.
This change was reported to OpenSSH in
https://lists.mindrot.org/pipermail/openssh-unix-dev/2022-November/040497.html
but was not acted on. It appears that OpenBSD subsequently received a
Coverity report for the same issue (their Coverity ID 405196) but fixed
only the specific instance reported by Coverity.

"adrl" is a pseudo-instruction used to calculate an address relative
to PC. It's not recognized by clang resulting in a compilation error.
I've stumbled upon it when trying to integrate the bsaes-armv7 assmebly
logic into FreeBSD kernel, which uses clang as it's default compiler.
Note that this affect the build only if BSAES_ASM_EXTENDED_KEY is
defined, which is not the default option in OpenSSL.
The solution here is to replace it with an add instruction.
This mimics what has already been done in !BSAES_ASM_EXTENDED_KEY logic.
Because of that I've marked this as trivial CLA.

This release fixes a number of security bugs and has minor new
features and bug fixes. Security fixes, from the release notes
(https://www.openssh.com/txt/release-9.3):
This release contains fixes for a security problem and a memory
safety problem. The memory safety problem is not believed to be
exploitable, but we report most network-reachable memory faults as
security bugs.
* ssh-add(1): when adding smartcard keys to ssh-agent(1) with the
per-hop destination constraints (ssh-add -h ...) added in OpenSSH
8.9, a logic error prevented the constraints from being
communicated to the agent. This resulted in the keys being added
without constraints. The common cases of non-smartcard keys and
keys without destination constraints are unaffected. This problem
was reported by Luci Stanescu.
* ssh(1): Portable OpenSSH provides an implementation of the
getrrsetbyname(3) function if the standard library does not
provide it, for use by the VerifyHostKeyDNS feature. A
specifically crafted DNS response could cause this function to
perform an out-of-bounds read of adjacent stack data, but this
condition does not appear to be exploitable beyond denial-of-
service to the ssh(1) client.
The getrrsetbyname(3) replacement is only included if the system's
standard library lacks this function and portable OpenSSH was not
compiled with the ldns library (--with-ldns). getrrsetbyname(3) is
only invoked if using VerifyHostKeyDNS to fetch SSHFP records. This
problem was found by the Coverity static analyzer.

Release notes are available at https://www.openssh.com/txt/release-9.2
OpenSSH 9.2 contains fixes for two security problems and a memory safety
problem. The memory safety problem is not believed to be exploitable.
These fixes have already been committed to OpenSSH 9.1 in FreeBSD.
Some other notable items from the release notes:
* ssh(1): add a new EnableEscapeCommandline ssh_config(5) option that
controls whether the client-side ~C escape sequence that provides a
command-line is available. Among other things, the ~C command-line
could be used to add additional port-forwards at runtime.
* sshd(8): add support for channel inactivity timeouts via a new
sshd_config(5) ChannelTimeout directive. This 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.
* sshd(8): add a sshd_config UnusedConnectionTimeout option to
terminate client connections that have no open channels for a
length of time. This complements the ChannelTimeout option above.
* sshd(8): add a -V (version) option to sshd like the ssh client has.
* scp(1), sftp(1): add a -X option to both scp(1) and sftp(1) to
allow control over some SFTP protocol parameters: the copy buffer
length and the number of in-flight requests, both of which are used
during upload/download. Previously these could be controlled in
sftp(1) only. This makes them available in both SFTP protocol
clients using the same option character sequence.
* ssh-keyscan(1): allow scanning of complete CIDR address ranges,
e.g. "ssh-keyscan 192.168.0.0/24". If a CIDR range is passed, then
it will be expanded to all possible addresses in the range
including the all-0s and all-1s addresses. bz#976
* ssh(1): support dynamic remote port forwarding in escape
command-line's -R processing. bz#3499

The following issues are patched:
- CVE-2022-42898 PAC parse integer overflows
- CVE-2022-3437 Overflows and non-constant time leaks in DES{,3} and arcfour
- CVE-2021-44758 NULL dereference DoS in SPNEGO acceptors
- CVE-2022-44640 Heimdal KDC: invalid free in ASN.1 codec
Note that CVE-2022-44640 is a severe vulnerability, possibly a 10.0
on the Common Vulnerability Scoring System (CVSS) v3, as we believe
it should be possible to get an RCE on a KDC, which means that
credentials can be compromised that can be used to impersonate
anyone in a realm or forest of realms.
Heimdal's ASN.1 compiler generates code that allows specially
crafted DER encodings of CHOICEs to invoke the wrong free function
on the decoded structure upon decode error. This is known to impact
the Heimdal KDC, leading to an invalid free() of an address partly
or wholly under the control of the attacker, in turn leading to a
potential remote code execution (RCE) vulnerability.
This error affects the DER codec for all extensible CHOICE types
used in Heimdal, though not all cases will be exploitable. We have
not completed a thorough analysis of all the Heimdal components
affected, thus the Kerberos client, the X.509 library, and other
parts, may be affected as well.
This bug has been in Heimdal's ASN.1 compiler since 2005, but it may
only affect Heimdal 1.6 and up. It was first reported by Douglas
Bagnall, though it had been found independently by the Heimdal
maintainers via fuzzing a few weeks earlier.
While no zero-day exploit is known, such an exploit will likely be
available soon after public disclosure.
