SUNRPC: Add SPDX IDs to some net/sunrpc/auth_gss/ files Files under net/sunrpc/auth_gss/ do not yet have SPDX ID tags. This directory is somewhat complicated because most of these files have license boilerplate that is not strictly GPL 2.0. In this patch I add ID tags where there is an obvious match. The less recognizable licenses are still under research.

SUNRPC: Add RPC based upcall mechanism for RPCGSS auth This patch implements a sunrpc client to use the services of the gssproxy userspace daemon. In particular it allows to perform calls in user space using an RPC call instead of custom hand-coded upcall/downcall messages. Currently only accept_sec_context is implemented as that is all is needed for the server case. File server modules like NFS and CIFS can use full gssapi services this way, once init_sec_context is also implemented. For the NFS server case this code allow to lift the limit of max 2k krb5 tickets. This limit is prevents legitimate kerberos deployments from using krb5 authentication with the Linux NFS server as they have normally ticket that are many kilobytes large. It will also allow to lift the limitation on the size of the credential set (uid,gid,gids) passed down from user space for users that have very many groups associated. Currently the downcall mechanism used by rpc.svcgssd is limited to around 2k secondary groups of the 65k allowed by kernel structures.

Merge branch 'nfs-for-next' of git://linux-nfs.org/~trondmy/nfs-2.6 into for-3.10 Note conflict: Chuck's patches modified (and made static) gss_mech_get_by_OID, which is still needed by gss-proxy patches. The conflict resolution is a bit minimal; we may want some more cleanup.
