February 2024 stabilization week

  Hi FreeBSD/main users,

the February 2024 stabilization week started with 03cc3489a02d that was tagged
as main-stabweek-2024-Feb.  At the moment of the tag creation we already knew
about several regression caused by libc/libsys split.

In the stabilization branch stabweek-2024-Feb we accumulated following cherry-picks
from FreeBSD/main:

1) closefrom() syscall was failing unless you have COMPAT_FREEBSD12 in kernel
   99ea67573164637d633e8051eb0a5d52f1f9488e
   eb90239d08863bcff3cf82a556ad9d89776cdf3f
2) nextboot -k broken on ZFS
   3aefe6759669bbadeb1a24a8956bf222ce279c68
   0c3ade2cf13df1ed5cd9db4081137ec90fcd19d0
3) libsys links to libc
   baa7d0741b9a2117410d558c6715906980723eed
4) sleep(3) no longer being a pthread cancellation point
   7d233b2220cd3d23c028bdac7eb3b6b7b2025125

We are aware of two regressions still unresolved:

1) libsys/rtld breaks bind 9.18 / mysql / java / ...
   https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=277222

   Konstantin, can you please check me? Is this the same issue fixed by
   baa7d0741b9a2117410d558c6715906980723eed or a different one?

2) panic: ... - wait_fw_init - mlx5_load_one
   https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=277211

Hopefully they would be fixed before March stabweek.

We closed the stabilization period on Thursday.

If you want to reap the fruits of the stabweek and you are very conservative
and want to use only changes that passed certain level of testing, you can use
the stabweek-2024-Feb branch. The branch is published at
https://github.com/glebius/FreeBSD/tree/stabweek-2024-Feb.

Otherwise I would recommend to use 7d233b2220cd3d23c028bdac7eb3b6b7b2025125 of
FreeBSD/main as a good point to update.  We did not observe any large or risky
changes in main during the week.
