glusterfsd: fix small memory leaks in glusterfsd-mgmt.c

2013-12-02T04:38:04+00:00

E.g. In glusterfs_volfile_fetch(), req.xdata.xdata_val is allocated
in dict_allocate_and_serialize() but not freed after mgmt_submit_request().

A survey of dict_allocate_and_serialize/_submit_request in
glusterfsd-mgmt.c shows no consistent pattern of freeing the xdata_val
and also the dict, which is a little disturbing. (Yes, clearly not
every place this occurs needs to be freed the same way.)

glusterfs, gfapi: fix symbol clash

2013-09-10T08:16:28+00:00

The callback structures in both protocol/client and glusterfsd,
gfapi used the same name for the actor table - gluster_cbk_actors.

CBKs are required only for the management connection, and the
actors of protocol/client are NOP functions. This supposed-to-be
NOP function dispatch tabble is actually ending up pointing to
the actor table of glusterfsd or gfapi.

These functions, even though set wrongly, are not even expected
to be called through the protocol/client callback path. Glusterd
however sends the FETCHSPEC (and other) notify callbacks to *all*
connected clients unconditionally, and there is a small period
of time when protocol/client is connected to glusterd for
PORTMAP query. If the FETCHSPEC callback notify is issued in
this window of time, we end up calling the wrong actor in the
client side resulting in a crash.

glusterfsd: Use dynamic volfile buffer

2013-07-31T07:38:40+00:00

Backport of
 fa78792 glusterfsd: Use dynamic volfile buffer
from the master branch.

Glusterfsd used a fixed buffer to store volfiles fetched via getspec.
This caused problems with large volfiles. Changining this to a dynamic
buffer allows large volfiles to be loaded in memory.

glusterd,glusterfsd,libgfapi: Client op-version

2013-02-06T20:17:06+00:00

This patch introduces op-version support for glusterfs clients.
Now, a client sends its supported op-versions during the volfile fetch request
and glusterd will return the volfile only if the client can support the current
op-version of the cluster.

This patch fixes the success check for xdr_to_generic function across the
codebase.

Also, cleans up the brick_op actors table in glusterfsd-mgmt.c to make sure that
the actors are called directly by rpcsvc.
