From 9d410c796067686b1e032d54ce475b7055537138 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Fri, 30 Oct 2009 05:03:53 +0000 Subject: net: fix sk_forward_alloc corruption On UDP sockets, we must call skb_free_datagram() with socket locked, or risk sk_forward_alloc corruption. This requirement is not respected in SUNRPC. Add a convenient helper, skb_free_datagram_locked() and use it in SUNRPC Reported-by: Francis Moreau Signed-off-by: Eric Dumazet Signed-off-by: David S.
