Pull audit updates from Paul Moore:
- Consolidate the loops in __audit_inode_child() to improve performance
When logging a child inode in __audit_inode_child(), we first run
through the list of recorded inodes looking for the parent and then
we repeat the search looking for a matching child entry. This pull
request consolidates both searches into one pass through the recorded
inodes, resuling in approximately a 50% reduction in audit overhead.
See the commit description for the testing details.

Merge tag 'selinux-pr-20251201' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux
Pull selinux updates from Paul Moore:
- Improve the granularity of SELinux labeling for memfd files
Currently when creating a memfd file, SELinux treats it the same as
any other tmpfs, or hugetlbfs, file. While simple, the drawback is
that it is not possible to differentiate between memfd and tmpfs
files.
This adds a call to the security_inode_init_security_anon() LSM hook
and wires up SELinux to provide a set of memfd specific access
controls, including the ability to control the execution of memfds.
As usual, the commit message has more information.
- Improve the SELinux AVC lookup performance
Adopt MurmurHash3 for the SELinux AVC hash function instead of the
custom hash function currently used. MurmurHash3 is already used for
the SELinux access vector table so the impact to the code is minimal,
and performance tests have shown improvements in both hash
distribution and latency.
See the commit message for the performance measurments.
- Introduce a Kconfig option for the SELinux AVC bucket/slot size
While we have the ability to grow the number of AVC hash buckets
today, the size of the buckets (slot size) is fixed at 512. This pull
request makes that slot size configurable at build time through a new
Kconfig knob, CONFIG_SECURITY_SELINUX_AVC_HASH_BITS.

selinux: Introduce a new config to make avc cache slot size adjustable

When the kernel build fails due to an objtool segfault, the error
message is a bit obtuse and confusing:
make[5]: *** [scripts/Makefile.build:503: drivers/scsi/qla2xxx/qla2xxx.o] Error 139

make[5]: *** Deleting file 'drivers/scsi/qla2xxx/qla2xxx.o'

make: *** [Makefile:248: __sub-make] Error 2
Add a signal handler to objtool which prints an error message like if
the local stack has overflown (for which there's a chance as objtool
makes heavy use of recursion):
drivers/scsi/qla2xxx/qla2xxx.o: error: SIGSEGV: objtool stack overflow!
or:
drivers/scsi/qla2xxx/qla2xxx.o: error: SIGSEGV: objtool crash!
Also, re-raise the signal so the core dump still gets triggered.

Pull LSM updates from Paul Moore:
- Rework the LSM initialization code
What started as a "quick" patch to enable a notification event once
all of the individual LSMs were initialized, snowballed a bit into a
30+ patch patchset when everything was done. Most of the patches, and
diffstat, is due to splitting out the initialization code into
security/lsm_init.c and cleaning up some of the mess that was there.
While not strictly necessary, it does cleanup the code signficantly,
and hopefully makes the upkeep a bit easier in the future.
Aside from the new LSM_STARTED_ALL notification, these changes also
ensure that individual LSM initcalls are only called when the LSM is
enabled at boot time. There should be a minor reduction in boot times
for those who build multiple LSMs into their kernels, but only enable
a subset at boot.
It is worth mentioning that nothing at present makes use of the
LSM_STARTED_ALL notification, but there is work in progress which is
dependent upon LSM_STARTED_ALL.

The x86 bootloader ID specification text uses hexadecimal
values without a 0x prefix:
D kexec-tools
E Extended (see ext_loader_type)
F Special (0xFF = undefined)
10 Reserved
11 Minimal Linux Bootloader
<http://sebastian-plotz.blogspot.de>
12 OVMF UEFI virtualization stack
13 barebox
Which beyond the ambiguity of '13' in isolation, also
made me fail a grep -wi '0xd' when I was looking for
the kexec bootloader ID definition and caused quite
a bit of head-scratching before I found out why it
didn't show up.
Furthermore, the actual explanatory text uses the 0x
prefix:
For boot loader IDs above T = 0xD, write T = 0xE to this field and
write the extended ID minus 0x10 to the ext_loader_type field.
Similarly, the ext_loader_ver field can be used to provide more than
four bits for the bootloader version.
So make it all both unambiguous, easy to grep and consistent
across the entire documentation by prefixing the IDs with 0x.

Extracting empty examples results in just the empty template being
generated and then validated. That's pointless and not free, so filter
out the schemas without any examples from the targets.
There's currently a little less than 10% of the binding schema files

initializing them upfront makes the code more obvious and easier, plus
it silences the warning.

The freeze_all_ptr check in filesystems_freeze_callback() introduced by
commit a3f8f86627 ("power: always freeze efivarfs") is reverse which
quite confusingly causes all file systems to be frozen when
filesystem_freeze_enabled is false.
On my systems it causes the WARN_ON_ONCE() in __set_task_frozen() to
trigger, most likely due to an attempt to freeze a file system that is
not ready for that.
Add a logical negation to the check in question to reverse it as
appropriate.

Using drm_mode_size_dumb() to compute the size of dumb buffers introduced
an 8-byte alignment constraint on the pitch that wasn’t present before.
Let’s remove this constraint, which isn’t necessarily required and may
cause buffers to be allocated larger than needed.
