[PATCH v3 0/3] audit: add support for openat2

The openat2(2) syscall was added in v5.6. Add support for openat2 to the audit syscall classifier and for recording openat2 parameters that cannot be captured in the syscall parameters of the SYSCALL record. Supporting userspace code can be found in https://github.com/rgbriggs/audit-userspace/tree/ghau-openat2 Supporting test case can be found in https://github.com/linux-audit/audit-testsuite/pull/103 Changelog: v3: - re-add commit descriptions that somehow got dropped - add new file to MAINTAINERS v2: - add include/linux/auditscm.h for audit syscall class macros due to syscall redefinition warnings: arch/x86/ia32/audit.c:3: ./include/linux/audit.h:12, ./include/linux/sched.h:22, ./include/linux/seccomp.h:21, ./arch/x86/include/asm/seccomp.h:5, ./arch/x86/include/asm/unistd.h:20, ./arch/x86/include/generated/uapi/asm/unistd_64.h:4: warning: "__NR_read" redefined #define __NR_read 0 ... ./arch/x86/include/generated/uapi/asm/unistd_64.h:338: warning: "__NR_rseq" redefined #define __NR_rseq 334 previous: arch/x86/ia32/audit.c:2: ./arch/x86/include/generated/uapi/asm/unistd_32.h:7: note: this is the location of the previous definition #define __NR_read 3 ... ./arch/x86/include/generated/uapi/asm/unistd_32.h:386: note: this is the location of the previous definition #define __NR_rseq 386 Richard Guy Briggs (3): audit: replace magic audit syscall class numbers with macros audit: add support for the openat2 syscall audit: add OPENAT2 record to list how MAINTAINERS | 1 + arch/alpha/kernel/audit.c | 10 ++++++---- arch/ia64/kernel/audit.c | 10 ++++++---- arch/parisc/kernel/audit.c | 10 ++++++---- arch/parisc/kernel/compat_audit.c | 11 +++++++---- arch/powerpc/kernel/audit.c | 12 +++++++----- arch/powerpc/kernel/compat_audit.c | 13 ++++++++----- arch/s390/kernel/audit.c | 12 +++++++----- arch/s390/kernel/compat_audit.c | 13 ++++++++----- arch/sparc/kernel/audit.c | 12 +++++++----- arch/sparc/kernel/compat_audit.c | 13 ++++++++----- arch/x86/ia32/audit.c | 13 ++++++++----- arch/x86/kernel/audit_64.c | 10 ++++++---- fs/open.c | 2 ++ include/linux/audit.h | 11 +++++++++++ include/linux/auditscm.h | 24 +++++++++++++++++++++++ include/uapi/linux/audit.h | 1 + kernel/audit.h | 2 ++ kernel/auditsc.c | 31 ++++++++++++++++++++++++------ lib/audit.c | 14 +++++++++----- lib/compat_audit.c | 15 ++++++++++----- 21 files changed, 169 insertions(+), 71 deletions(-) create mode 100644 include/linux/auditscm.h -- 2.27.0
