git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit
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.
- Combine kmalloc()/memset() into kzalloc() in audit_krule_to_data()
- Comment fixes

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.

overflows
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[4]: *** [scripts/Makefile.build:556: drivers/scsi/qla2xxx] Error 2
make[3]: *** [scripts/Makefile.build:556: drivers/scsi] Error 2
make[2]: *** [scripts/Makefile.build:556: drivers] Error 2
make[1]: *** [/home/jpoimboe/git/linux/Makefile:2013: .] Error 2
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.
[ mingo: Applied a build fix, added more comments and prettified the code. ]

git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm
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.

A recent spinlock guard conversion used the wrong guard so that

Based on a cursory look this appears to be safe currently, but it could
cause a deadlock if one of these helpers are ever called in interrupt
context.

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
without examples. Removing them improves the build time by ~6%.

xe_sync_in_fence_get() uses the same kind of mismatched fence array
allocation vs looping logic that was previously noted and changed by
commit 0a4c2ddc711a ("drm/xe/vm: Use for_each_tlb_inval() to calculate
invalidation fences"). As with that commit, the mismatch doesn't cause
any problem at the moment since for_each_tlb_inval() loops the same
number of times as XE_MAX_GT_PER_TILE (2). However we don't want to
assume that these will always be the same in the future, so switch to
using for_each_tlb_inval() in both places to future-proof the code.

'version' is an enum, thus cast of pointer on 64-bit compile test with
clang W=1 causes:
rockchip_pdm.c:583:17: error: cast to smaller integer type 'enum rk_pdm_version' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
This was already fixed in commit 49a4a8d12612 ("ASoC: rockchip: Fix
Wvoid-pointer-to-enum-cast warning") but then got bad in
commit 9958d85968ed ("ASoC: Use device_get_match_data()").
Discussion on LKML also pointed out that 'uintptr_t' is not the correct
type and either 'kernel_ulong_t' or 'unsigned long' should be used,
with several arguments towards the latter [1].

clang W=1 builds warn:
nau8325.c:430:13: error: variable 'n2_max' is uninitialized when used here [-Werror,-Wuninitialized]
which are false positive, because the variables will be always
initialized when used (guarded by mclk_max!=0 check). However
initializing them upfront makes the code more obvious and easier, plus
it silences the warning.

At the moment the TTM code has a few places which exibit sub-optimal
patterns regarding local variable usage:
* Having a local with some object cached but not always using it.
* Having a local for a single use object member access.
* Failed opportunities to use a local to cache a pointer.
Lets tidy this a little bit and apply some more consistency.
It is mostly for consistency and redability but I have also checked that
there are not negative code generation effects. In fact there are more
positives:

- Collect R-bs

When we re-assign a slot to a different VM, we need to make sure the
old VM caches are flushed before doing the switch. Specialize
panthor_mmu_as_disable() so we can skip the slot programmation while
still getting the cache flushing, and call this helper from
panthor_vm_active() when an idle slot is recycled.

It appears the timeout can still be enabled when we reach that point,
because of the asynchronous progress check done on queues that resets
the timer when jobs are still in-flight, but progress was made.
We could add more checks to make sure the timer is not re-enabled when
a group can't run anymore, but we don't have a group to pass to
queue_check_job_completion() in some context.
It's just as safe (we just want to be sure the timer is stopped before
we destroy the queue) and simpler to drop the WARN_ON() in
group_free_queue().
v2:
