[PATCH] [BZ905179] audit: omit check for uid and gid validity in audit rules and data

[Richard Guy Briggs]

audit rule additions containing "-F auid!=4294967295" were failing with EINVAL.

UID_INVALID (and GID_INVALID) is actually a valid uid (gid) for setting and
testing against audit rules.  Remove the check for invalid uid and gid when
parsing rules and data for logging.

Revert part of ca57ec0f00c3f139c41bf6b0a5b9bcc95bbb2ad7 (2012-09-11) to fix
this.
