rpc_pipe: Drop memory allocation cast

2014-07-12T22:43:44+00:00

Drop cast on the result of kmalloc and similar functions.

The semantic patch that makes this change is as follows:

// 
@@
type T;
@@

- (T *)
  (\(kmalloc\|kzalloc\|kcalloc\|kmem_cache_alloc\|kmem_cache_zalloc\|
   kmem_cache_alloc_node\|kmalloc_node\|kzalloc_node\)(...))
//

rpc_pipe: fix cleanup of dummy gssd directory when notification fails

2013-12-10T17:39:53+00:00

Currently, it could leak dentry references in some cases. Make sure
we clean up properly.

sunrpc: add an "info" file for the dummy gssd pipe

2013-12-06T18:06:34+00:00

rpc.gssd expects to see an "info" file in each clntXX dir. Since adding
the dummy gssd pipe, users that run rpc.gssd see a lot of these messages
spamming the logs:

    rpc.gssd[508]: ERROR: can't open /var/lib/nfs/rpc_pipefs/gssd/clntXX/info: No such file or directory
    rpc.gssd[508]: ERROR: failed to read service info

Add a dummy gssd/clntXX/info file to help silence these messages.

rpc_pipe: remove the clntXX dir if creating the pipe fails

2013-12-06T18:06:33+00:00

In the event that we create the gssd/clntXX dir, but the pipe creation
subsequently fails, then we should remove the clntXX dir before
returning.

sunrpc: replace sunrpc_net->gssd_running flag with a more reliable check

2013-12-06T18:06:31+00:00

Now that we have a more reliable method to tell if gssd is running, we
can replace the sn->gssd_running flag with a function that will query to
see if it's up and running.

There's also no need to attempt an upcall that we know will fail, so
just return -EACCES if gssd isn't running. Finally, fix the warn_gss()
message not to claim that that the upcall timed out since we don't
necesarily perform one now when gssd isn't running, and remove the
extraneous newline from the message.

sunrpc: create a new dummy pipe for gssd to hold open

2013-12-06T18:06:30+00:00

rpc.gssd will naturally hold open any pipe named */clnt*/gssd that shows
up under rpc_pipefs. That behavior gives us a reliable mechanism to tell
whether it's actually running or not.

Create a new toplevel "gssd" directory in rpc_pipefs when it's mounted.
Under that directory create another directory called "clntXX", and then
within that a pipe called "gssd".

We'll never send an upcall along that pipe, and any downcall written to
it will just return -EINVAL.

Rename simple_delete_dentry() to always_delete_dentry() and export it.
Export simple_dentry_operations, while we are at it, and get rid of
