been "node Node", the second "node" is not capitalized in the reference
file (yet). We'll bring it back capitalized to avoid it from triggering

Revert for now as we are currently in stabweek.
This reverts commit 9562994a7a.
Reported by: mav
pf was too strict when validating SCTP tags. When a server receives a
retransmitted INIT it will reply with a random initiate tag every time.
However, pf saves the first initiate tag and expects every subsequent INIT_ACK
retransmission to have the same tag. This is not the case, leading to endless
INIT/INIT_ACK cycles.
Allow the tag to be updated as long as we've not gone past COOKIE_WAIT.
Add a test case to verify this.

Because setcred() has (always) treated the effective GID separately from
the supplementary groups, when cr_groups[0] was storing the effective
GID, it internally needed to build an array containing both the
effective GID and the specified supplementary groups to eventually call
crsetgroups_internal().
As kern_setcred() was only used to actually implement
user_setcred()/sys_setcred(), which need to allocate a buffer to copy in
the userland groups array into, some optimization was put in place where
these would allocate an array with one more element than
'wc_supp_groups', copyin() the latter into the subarray starting at
index 1 and pass the pointer to the whole array to kern_setcred() in
'preallocated_groups'. This would allow kern_setcred() not to have to
allocate memory again to make room for the additional effective GID.
Since commit be1f7435ef ("kern: start tracking cr_gid outside of
cr_groups[]"), crsetgroups_internal() only takes supplementary groups,
so this machinery has become obsolete. It was not removed as part of
that commit, but just minimally amended to simplify the changes and
lower the risks. Finally remove it.

If the basis for supplementary groups are the current ones, we do not
need to fetch them when they are to be replaced entirely (which we
already have been doing), as in the '!start_from_current_groups' case,
but specifically also when they are not going to be touched at all.
This change in passing makes the modified code block's comment saying
that SETCREDF_SUPP_GROUPS need not be set here correct.

Prior to commit 0c511bafdd, each time
snl_realloc_msg_buffer was called, it called snl_allocz to request a
new buffer. If an existing linear buffer was used, then after the
call, the linear buffer effectively contained the old buffer contents
followed by the new buffer (so there was definitely wasted memory),
but the linear buffer state was consistent (lb->offset correctly
accounted for both copies). For example, if the initial linear buffer
was 256 bytes in size, lb->size would be 256. Using 16 bytes followed
by 32 bytes would first set lb->offset to 16, then the second realloc
would allocate 48 bytes (16 + 32) setting lb->offset to 64 (16 + 48).
Commit 0c511bafdd aimed to avoid this
memory waste by resetting the base pointer to the start of the
existing linear buffer if the new allocation was later in the same
linear buffer. This avoided some of the waste, but broke the
accounting. Using the same example above, the second realloc would
reuse the pointer at an offset of 0, but the linear buffer would still
claim that 64 bytes was allocated via lb->offset rather than the true
allocation of 48 bytes.
One approach to fix this would be to "extend" the allocation of an
existing linear buffer where a realloc would try to increase
lb->offset without setting a new base pointer so long as there was
still room remaining in the linear buffer for the new request.
However, this change takes a simpler approach. If snl_allocz()
returned an allocation from a new linear buffer, just claim the entire
linear buffer for use by the snl_writer ensuring the accounting is
correct in both the linear buffer and the snl writer. With this
approach, the initial snl_writer size would be 256 bytes for a 256
byte linear buffer and would only grow if it needs to allocate an
entirely new linear buffer.

[Driver] Enable outline atomics for FreeBSD/aarch64 (#156089)
The compiler_rt helper functions have been built since 12.4, 13.1, 14
and anything newer.
This reverts commit bd27bd1f51.
Only some people (including the release manager, unfortunately) ran into
build issues with the previous iteration of this commit, because they
were bootstrapping the compiler, either via the WITHOUT_SYSTEM_COMPILER
src.conf(5) setting, or because the build system determined that their
base system compiler was out of date.
The bootstrapped compiler would then enable outline atomics and compile
libgcc_s with these, but because libgcc_s is linked with -nodefaultlibs,
it could not find the helper routines in libcompiler_rt.a.
In contrast, people who did not bootstrap the compiler never saw any
issues, because libgcc_s was built using their 'old' base system
compiler, and so libgcc_s would not contain any calls to those helper
routines.
Fix this by ensuring that libgcc_s is linked against libcompiler_rt.a
explicitly, similar to some other binaries and libraries that are built
with -nodefaultlibs.
Also, bump FREEBSD_CC_VERSION to ensure that everybody gets the updated
compiler with outline atomics enabled. (This should have been done in
the first iteration of this commit, because the error would have shown
up right away then.)

Contrary to the claim made in a previous commit, removing KDE and

image builds using an out-of-date tree, and became visible when the
15.0-RC3 images were built.)
Limit the emacs packages shipped on the DVD to the "nox" flavor;
this brings the disk image down to 4.407 GB, aka under the 4.7 GB
limit for standard DVDs.
