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 * tag 'audit-pr-20251201' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit: audit: merge loops in __audit_inode_child() audit: Use kzalloc() instead of kmalloc()/memset() in audit_krule_to_data() audit: fix comment misindentation in audit.h

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. * tag 'selinux-pr-20251201' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: improve bucket distribution uniformity of avc_hash() selinux: Move avtab_hash() to a shared location for future reuse selinux: Introduce a new config to make avc cache slot size adjustable memfd,selinux: call security_inode_init_security_anon()

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. - Make better use of the seq_put*() helpers in device_cgroup * tag 'lsm-pr-20251201' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: (36 commits) lsm: use unrcu_pointer() for current->cred in security_init() device_cgroup: Refactor devcgroup_seq_show to use seq_put* helpers lsm: add a LSM_STARTED_ALL notification event lsm: consolidate all of the LSM framework initcalls selinux: move initcalls to the LSM framework ima,evm: move initcalls to the LSM framework lockdown: move initcalls to the LSM framework apparmor: move initcalls to the LSM framework safesetid: move initcalls to the LSM framework tomoyo: move initcalls to the LSM framework smack: move initcalls to the LSM framework ipe: move initcalls to the LSM framework loadpin: move initcalls to the LSM framework lsm: introduce an initcall mechanism into the LSM framework lsm: group lsm_order_parse() with the other lsm_order_*() functions lsm: output available LSMs when debugging lsm: cleanup the debug and console output in lsm_init.c lsm: add/tweak function header comment blocks in lsm_init.c lsm: fold lsm_init_ordered() into security_init() lsm: cleanup initialize_lsm() and rename to lsm_init_single() ...
2025-12-03x86/boot/Documentation: Prefix hexadecimal literals with 0xIngo Molnar
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. Signed-off-by: Ingo Molnar <mingo@kernel.org> Cc: "H.

2025-12-03ASoc: qcom: q6afe: fix bad guard conversionJohan Hovold
A recent spinlock guard conversion used the wrong guard so that interrupts are no longer disabled while holding the port list lock. 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.
