rpc: bring in root-squashing behavior in rpc

2013-03-05T07:44:04+00:00

* requests coming in as root are converted to nfsnobody

* with open-behind some acl checks wont happen and nfsnobody
  can read the file "whose owner is root and other users do not
  have permission to read the file". This is becasue open-behind
  does not send the open to the brick and sends success to the
  application, thus the acl related tests on the file wont happen
  which would have prevented the file from being opened.

protocol/client: Avoid double free of frame

2013-02-05T06:11:51+00:00

When client_submit_request fails it calls cbk. The cleanups should
happen only in cbk. The code committed as part of
http://review.gluster.org/4357 violates this. Also found that
clnt_release_reopen_fd violates this as well.
This patch fixes these issue.

protocol/server: upon server_connection_put, set xl_private of the transport to

2013-02-03T22:10:02+00:00

 NULL

 Suppose the get_xlator_by_name returns NULL and the connection is put back
 then update the xl_private of the transport by setting to NULL. Otherwise
 server_connection_put would have freed the connection object and xl_private
 of the transport would still be pointing to the same location which is
 freed, thus leading to a segfault when the location is accessed.

protocol/client: Periodically attempt reopens

2013-02-03T19:33:31+00:00

If the brick is taken down and the hard disk is replaced
and the brick is brought back up, the re-opens of the open-fds
will fail because the file is not present on the brick.
Re-opens are not attempted even if the files are re-created by
self-heal until the brick is brought down after the files are
re-created and brought back up. This is a problem with a VM-store
in a replica-setup.  Until the fd is re-opened the writes will
never happen on the brick where the hard-disk is replaced.
To handle this situation gracefully, client xlator is enhanced
to perform finodelk, fxattrop, writev, readv using anonymous fds
if the file is yet to be re-opened. If the fop succeeds then client
xlator attempts re-open.
