From 8e35f8e7c61c88f9a979a4e6f7f4ffd4c158a88a Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 2 Nov 2010 09:11:55 -0400 Subject: NLM: Fix a regression in lockd Nick Bowler reports: There are no unusual messages on the client... but I just logged into the server and I see lots of messages of the following form: nfsd: request from insecure port (192.168.8.199:35766)! nfsd: request from insecure port (192.168.8.199:35766)! nfsd: request from insecure port (192.168.8.199:35766)! nfsd: request from insecure port (192.168.8.199:35766)! nfsd: request from insecure port (192.168.8.199:35766)! Bisected to commit 9247685088398cf21bcb513bd2832b4cd42516c4 (SUNRPC: Properly initialize sock_xprt.srcaddr in all cases) Apparently, removing the 'transport->srcaddr.ss_family = family' from xs_create_sock() triggers this due to nlmclnt_lookup_host() incorrectly initialising the srcaddr family to AF_UNSPEC.
