Subject: [PATCH 0/4 net-2.6.25] Proper netlink kernel sockets disposal.
Date: Fri, 18 Jan 2008 15:51:47 +0300 [thread overview]
Message-ID: <4790A0E3.9080006@sw.ru> (raw)
Alexey Dobriyan found, that virtualized netlink kernel sockets (fibl &
rtnl) are leaked during namespace start/stop loop.
Leaking fix (simple and obvious) reveals that netlink kernel socket
disposal leads to OOPSes:
- nl_table[protocol]->listeners is double freed
- sometimes during namespace stop netlink_sock_destruct
BUG_TRAP(!atomic_read(&sk->sk_rmem_alloc)); is hit
This set address all these issues.
