gNFS: Subdir mount does not work on UDP proto
After enabling nfs.mount-udp, mounting a subdir on a volume over NFS fails. Because mountudpproc3_mnt_3_svc() invokes nfs3_rootfh() which internally calls mnt3_mntpath_to_export() to resolve the mount path. mnt3_mntpath_to_export() just works if the mount path requested is volume itself. It is not able to resolve, if the path is a subdir inside the volume. MOUNT over TCP uses mnt3_find_export() to resolve subdir path but UDP can't use this routine because mnt3_find_export() needs the req data (of type rpcsvc_request_t) and it's available only for TCP version of RPC. FIX: (1) Use syncop_lookup() framework to resolve the MOUNT PATH by breaking it into components and resolve component-by-component. i.e. glfs_resolve_at () API from libgfapi shared object. (2) If MOUNT PATH is subdir, then make sure subdir export is not disabled. (3) Add auth mechanism to respect nfs.rpc-auth-allow/reject and subdir auth i.e. nfs.export-dir (4) Enhanced error handling for MOUNT over UDP Change-Id: I42ee69415d064b98af4f49773026562824f684d1 BUG: 1118311 Signed-off-by: Santosh Kumar Pradhan <spradhan@redhat.com> Reviewed-on: http://review.gluster.org/8346 Reviewed-by: soumya k <skoduri@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Niels de Vos <ndevos@redhat.com>
