Subject: [PATCH] taskstats: fix? sk_buff leak
Date: Sun, 29 Oct 2006 16:24:49 +0300 [thread overview]
Message-ID: <20061029132449.GA1142@oleg> (raw)
Compile tested only, and I know nothing about net/. Needs an ack from
maintainer.
'return genlmsg_cancel()' in taskstats_user_cmd/taskstats_exit_send looks
wrong to me. Unless we pass 'rep_skb' to the netlink layer we own sk_buff,
yes? This means we should always do kfree_skb() on failure.
