AUDIT: Wait for backlog to clear when generating messages.
Add a gfp_mask to audit_log_start() and audit_log(), to reduce the amount of GFP_ATOMIC allocation -- most of it doesn't need to be GFP_ATOMIC. Also if the mask includes __GFP_WAIT, then wait up to 60 seconds for the auditd backlog to clear instead of immediately abandoning the message. The timeout should probably be made configurable, but for now it'll suffice that it only happens if auditd is actually running. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
