From 27459f0940e16c68e080f5fc7e85aa9eb3f74528 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 12 Feb 2007 00:53:34 -0800 Subject: [PATCH] knfsd: SUNRPC: Provide room in svc_rqst for larger addresses Expand the rq_addr field to allow it to contain larger addresses. Specifically, we replace a 'sockaddr_in' with a 'sockaddr_storage', then everywhere the 'sockaddr_in' was referenced, we use instead an accessor function (svc_addr_in) which safely casts the _storage to _in.
