Subject: [SCTP]: Add RCU synchronization around sctp_localaddr_list
X-Git-Tag: v2.6.23-rc7~33^2~9
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=293035479942400a7fe8e4f72465d4e4e466b91a;p=pandora-kernel.git

[SCTP]: Add RCU synchronization around sctp_localaddr_list

sctp_localaddr_list is modified dynamically via NETDEV_UP
and NETDEV_DOWN events, but there is not synchronization
between writer (even handler) and readers.  As a result,
the readers can access an entry that has been freed and
crash the sytem.
