From 301e99ce4a2f42a317129230fd42e6cd874c64b0 Mon Sep 17 00:00:00 2001 From: Neil Brown Date: Sun, 28 Feb 2010 22:01:05 -0500 Subject: nfsd: ensure sockets are closed on error One the changes in commit d7979ae4a "svc: Move close processing to a single place" is: err_delete: - svc_delete_socket(svsk); + set_bit(SK_CLOSE, &svsk->sk_flags); return -EAGAIN; This is insufficient. The recvfrom methods must always call svc_xprt_received on completion so that the socket gets re-queued if there is any more work to do. This particular path did not make that call because it actually destroyed the svsk, making requeue pointless. When the svc_delete_socket was change to just set a bit, we should have added a call to svc_xprt_received, This is the problem that b0401d7253 attempted to fix, incorrectly. Signed-off-by: J.
