rwatson 2009-03-16 17:25:09 UTC FreeBSD src repository Modified files: (Branch: RELENG_7) sys/security/audit audit.c audit.h audit_syscalls.c sys/sys proc.h Log: SVN rev 189890 on 2009-03-16 17:25:09Z by rwatson Merge r189570 from head to stable/7: Add a new thread-private flag, TDP_AUDITREC, to indicate whether or not there is an audit record hung off of td_ar on the current thread. Test this flag instead of td_ar when auditing syscall arguments or checking for an audit record to commit on syscall return. Under these circumstances, td_pflags is much more likely to be in the cache (especially if there is no auditing of the current system call), so this should help reduce cache misses in the system call return path.
