From 71afa85e798ebc81054164c947b189d163c92b30 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Sat, 16 Mar 2013 15:54:16 -0400 Subject: [PATCH] SUNRPC: Missing module alias for auth_rpcgss.ko Commit f344f6df "SUNRPC: Auto-load RPC authentication kernel modules", Mon Mar 20 13:44:08 2006, adds a request_module() call in rpcauth_create() to auto-load RPC security modules when a ULP tries to create a credential of that flavor. In rpcauth_create(), the name of the module to load is built like this: request_module("rpc-auth-%u", flavor); This means that for, say, RPC_AUTH_GSS, request_module() is looking for a module or alias called "rpc-auth-6". The GSS module is named "auth_rpcgss", and commit f344f6df does not add any new module aliases. There is also no such alias provided in /etc/modprobe.d on my system (Fedora 16). Without this alias, the GSS module is not loaded on demand. This is used by rpcauth_create(). The pseudoflavor_to_flavor() call can return RPC_AUTH_GSS, which is passed to request_module().
