rwatson 2004-10-12 17:36:45 UTC FreeBSD src repository Modified files: (Branch: RELENG_5) sys/netinet tcp_output.c 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). Approved by: re (kensmith) Revision Changes Path 1.100.2.1 +14 -2 src/sys/netinet/tcp_output.c
