SVN rev 208953 on 2010-06-09 16:42:42Z by rrs
Fix serveral bugs all having to do with freeing an
sctp_inpcb:
1) Make sure not to remove the flag on the PCB until
after the close() caller is back in control with the
lock. Otherwise a quickly freeing assoc could kill the
inpcb and cause a panic.
2) Make sure all calls to log_closing have not released
the locks before calling the log function, we don't
want the logging function to crash us due to a freed
inpcb.
3) Make sure that when we get to the end, we release all
locks (after removing them from view) and as long as
we are NOT the inp-kill timer removing the inp, call
the callout_drain() function so a racing timer won't
later call in and cause a racing crash.
