To be honest, including this in the audit tree is a bit of a stretch, but it does help move audit a little further along towards proper syscall auditing for all arches, and everyone else seemed to agree that audit was a "good" spot for this to land (or maybe they just didn't want to merge it? dunno.). - We can now audit time/NTP adjustments. - We continue the work to connect associated audit records into a single event" * tag 'audit-pr-20190507' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit: (21 commits) audit: fix a memory leak bug ntp: Audit NTP parameters adjustment timekeeping: Audit clock adjustments audit: purge unnecessary list_empty calls audit: link integrity evm_write_xattrs record to syscall event syscall_get_arch: add "struct task_struct *" argument unicore32: define syscall_get_arch() Move EM_UNICORE to uapi/linux/elf-em.h nios2: define syscall_get_arch() nds32: define syscall_get_arch() Move EM_NDS32 to uapi/linux/elf-em.h m68k: define syscall_get_arch() hexagon: define syscall_get_arch() Move EM_HEXAGON to uapi/linux/elf-em.h h8300: define syscall_get_arch() c6x: define syscall_get_arch() arc: define syscall_get_arch() Move EM_ARCOMPACT and EM_ARCV2 to uapi/linux/elf-em.h audit: Make audit_log_cap and audit_copy_inode static audit: connect LOGIN record to its syscall record ...
