Log:
Merge tcp_output.c:1.103 from HEAD to RELENG_5:
date: 2004/10/09 16:48:51; author: rwatson; state: Exp; lines: +14 -2
Acquire the send socket buffer lock around tcp_output() activities
reaching into the socket buffer. This prevents a number of potential
races, including dereferencing of sb_mb while unlocked leading to
a NULL pointer deref (how I found it). Potentially this might also
explain other "odd" TCP behavior on SMP boxes (although haven't
seen it reported).
