[PATCH net 2/2] geneve: avoid using stale geneve socket.

2016-10-27 Thread Pravin B Shelar
This patch is similar to earlier vxlan patch. Geneve device close operation frees geneve socket. This operation can race with geneve-xmit function which dereferences geneve socket. Following patch uses RCU mechanism to avoid this situation. Signed-off-by: Pravin B Shelar --- drivers/net/geneve.c
