From 4e33fa14faecc150e97c0e4f2320745bdc7b7112 Mon Sep 17 00:00:00 2001 From: Masahide NAKAMURA Date: Tue, 5 Dec 2006 13:48:27 -0800 Subject: [PATCH] [IPV6] RAW: Don't release unlocked sock. When user builds IPv6 header and send it through raw socket, kernel tries to release unlocked sock. (Kernel log shows "BUG: bad unlock balance detected" with enabled debug option.) The lock is held only for non-hdrincl sock in this function then this patch fix to do nothing about lock for hdrincl one. Signed-off-by: Masahide NAKAMURA Signed-off-by: David S.
