Fix spurious brick disconnects

2013-05-01T03:12:52+00:00

Spurious disconnect were caused by a race condition inside
rpc_transport_ref()/rpc_transport_unref() that allowed the refcount
to drop to zero while the transport was still in use. The race
condition is made possible because of an uninitiaized mutex
produced when socket_server_event_handler() copies the transport

glusterd: Fixed spurious wakeups in glusterd syncops

2013-04-17T12:46:43+00:00

glusterd syncops perform a barrier_wake whenever rpc_clnt_submit returned -1.
This is based on the wrong assumption that the cbkfn wasn't called.
This would result in one more wakeup than there ought to be.

rpc: before freeing the volume options object, delete it from the list

2013-04-12T17:07:23+00:00

* Suppose there is an xlator option which is considered by the xlator
  only if the source was built with debug mode enabled (the only example
  in the current code base is run-with-valgrind option for glusterd), then
  giving that option would make the process crash if the source was not
  built with debug mode enabled.

  Reason:
  In rpc, after getting the options symbol dynamically, it was stored in the
  newly allocated volume options structure and the structure's list head was
  added to the xlator's volume_options list. But while freeing the structure
  the list was not deleted. Thus when the list was traversed, already freed
  structure was accessed leading to segfault.

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.
