SVN rev 183473 on 2008-09-29 19:19:27Z by rwatson
Merge r183418 from head to stable/7:
When an inpcb doesn't have a socket but the inpcb is passed to ipfw
in the transmit path, such as TCPS_TIMEWAIT, fail the credential
extraction immediately rather than acquiring locks and looking up
the inpcb on the global lists in order to reach the conclusion that
the credential extraction has failed.
This is more efficient, but more importantly, it avoids lock
recursion on the inpcbinfo, which is no longer allowed with rwlocks.
This appears to have been responsible for at least two reported
panics.
