Ok. I built and ran a kernel with it here, and ran some selinux tests, and it looked good. It has some side benefits for SELinux even beyond the comm information, e.g. capturing the exe= upon syscall exit lets us get it cleanly without having to worry about mmap sem locking by the caller (which was an issue for mmap/mprotect previously) and moving the task-related audit handling to syscall exit should avoid having bogus information included for our networking checks that occur outside of process context. Tools like seaudit may need to be updated to get the task-related info from the subsequent syscall audit record instead of from the avc-generated record, but they can correlate it based on the timestamp/serial.

One further change that should be made is to use something like audit_log_untrustedstring on the comm and on the exe path.
