gNFS: Subdir mount does not work on UDP proto

2014-10-07T07:51:29+00:00

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

nfs: prevent assertion error with MOUNT over UDP

2014-07-07T17:28:47+00:00

The MOUNT service over UDP runs in a separate thread. This thread does
not have the correct *THIS xlator set. *THIS points to the global (base)
xlator structure, but GF_CALLOC() requires it to be the NFS-xlator so
that assertions can get validated correctly.

This is solved by passing the NFS-xlator to the pthread function, and
setting the *THIS pointer explicitly in the new thread.

It seems that on occasion (needs further investigation) MOUNT over UDP
does not unregister itself. There can also be issues when the kernel NLM
implementation has been registered at portmap/rpcbind, so adding some
unregister procedures in the cleanup of the test-cases.

dual license: update remaining files with correct license text

2013-10-24T14:58:19+00:00

Sayan Saha has previously approved changing everthing to dual license
but somehow we have missed changing these files.

I am explicitly not updating the copyright dates as nothing else that's
copyrightable has changed in these files with the license change
