From 9db619e66503494e41159de3c76fafabe80d016b Mon Sep 17 00:00:00 2001 From: Wolfgang Walter Date: Thu, 20 Sep 2007 15:51:46 -0400 Subject: [PATCH 1/1] rpc: fix garbage in printk in svc_tcp_accept() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit we upgraded the kernel of a nfs-server from 2.6.17.11 to 2.6.22.6. Since then we get the message lockd: too many open TCP sockets, consider increasing the number of nfsd threads lockd: last TCP connect from ^\\236^\É^D These random characters in the second line are caused by a bug in svc_tcp_accept. (Note: there are two previous __svc_print_addr(sin, buf, sizeof(buf)) calls in this function, either of which would initialize buf correctly; but both are inside "if"'s and are not necessarily executed. This is less obvious in the second case, which is inside a dprintk(), which is a macro which expands to an if statement.) Signed-off-by: Wolfgang Walter Signed-off-by: J.
