[libc++][AIX] Enable LIBCPP_SHARED_PTR_DEFINE_LEGACY_INLINE_FUNCTIONS on AIX (#179784)
This PR enables the `LIBCPP_SHARED_PTR_DEFINE_LEGACY_INLINE_FUNCTIONS`
macro on AIX because the functions guarded by this macro are required for
backward compatibility.
[LoopUnrollPass] Indent `LLVM_DEBUG()` messages based on our depth in the `tryToUnrollLoop()` call graph (#178945)
Unify the ad-hoc use of whitespace in `LLVM_DEBUG()` messages.
This approach should also make it easier to see which loop debug
messages correspond to and which part of the loop unrolling heuristics
each message corresponds to.
NAS-139737 / 26.0.0-BETA.1 / fix TooManyOpenFiles leak (#18177)
Fixes Too many open files (EMFILE) caused by unbounded concurrent
systemctl restart ix-vendor subprocess spawning in response to
rapid-fire ipaddress.change netlink events.
Root cause: Every IP address change event fired a new create_task that
spawned a systemctl restart ix-vendor subprocess. During network
reconfiguration bursts, hundreds of concurrent subprocesses piled up,
each opening pipes/fds, until the file descriptor limit was exhausted.
Fix:
- Replace `subprocess.run(["systemctl", "restart", "ix-vendor"])` with
`call_unit_action_and_wait("ix-vendor.service", "Restart")` where the
latter communicates with systemd over D-Bus instead of spawning
subprocesses, eliminating fd pressure entirely
- Guard with `IX_VEND_LOCK` (asyncio.Lock) using a skip-if-locked
pattern to coalesce concurrent restart requests into a single operation
NAS-139619 / 25.10.2 / Fix grub.cfg corruption during HA standby reboot (by ixhamza) (#18178)
When toggling STIG/FIPS on an HA system, the standby controller can end
up stuck in the GRUB console with an empty `grub.cfg`. This occurs
because two `failover.reboot.other_node` calls are dispatched
back-to-back: one from the middleware automatically and second one from
the WebUI reboot dialog with default options (`graceful=False`). The
second call is queued behind the first via the `reboot_standby` job
lock, and fires as soon as the standby finishes booting from the first
reboot during the `post_init` checkpoint which runs `update-grub`.
`update-grub` is a wrapper around `grub-mkconfig`, which writes the
final config using:
```
cat grub.cfg.new > grub.cfg
```
The shell `>` truncates grub.cfg to zero bytes before `cat` writes the
new content. `grub-mkconfig` does not fsync at any point. When the
second reboot kills the process, `grub.cfg` is left as a zero-byte file

and drops to the GRUB console.

[MLIR][Math] Fix math.ceil expansion to avoid undefined behavior on Inf/NaN (#170028)
Fixes #151786
The original `ceilf` expansion lowers to `fptosi`, which produces poison
for Inf, and any subsequent use leads to undefined behavior. This patch
adds a safe path, similar to the existing `round` expansion, for large
or special inputs and avoids the UB.
