* NFSv4: Fix the underestimate of NFSv4 open request sizeTrond Myklebust2007-07-10
| | | | | | | The maximum size depends on the filename size and a number of other elements which are currently not being counted. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* NFS: Replace NFS_I(inode)->req_lock with inode->i_lockTrond Myklebust2007-07-10
| | | | | | | There is no justification for keeping a special spinlock for the exclusive use of the NFS writeback code. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Clean up _nfs4_proc_lookup() vs _nfs4_proc_lookupfh()Trond Myklebust2007-07-10
| | | | | | | They differ only slightly in the arguments they take. Why have they not been merged? Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* SUNRPC: Ensure RPCSEC_GSS destroys the security context when freeing a credTrond Myklebust2007-07-10
| | | | | | | Do so by set the gc_proc field to RPC_GSS_PROC_DESTROY, and then sending a NULL RPC call. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Ensure that the struct gss_auth lifetime exceeds the credential'sTrond Myklebust2007-07-10
| | | | | | | Add a refcount in order to ensure that the gss_auth doesn't disappear from underneath us while we're freeing up GSS contexts. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Remove the tk_auth macro...Trond Myklebust2007-07-10
| | | | | | | | We should almost always be deferencing the rpc_auth struct by means of the credential's cr_auth field instead of the rpc_clnt->cl_auth anyway. Fix up that historical mistake, and remove the macro that propagated it. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Allow rpc_auth to run clean up before the rpc_client is destroyedTrond Myklebust2007-07-10
| | | | | | | RPCSEC_GSS needs to be able to send NULL RPC calls to the server in order to free up any remaining GSS contexts. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | | | Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Add the helper function 'rpc_call_null()'Trond Myklebust2007-07-10
| | | | | | | Does a NULL RPC call and returns a pointer to the resulting rpc_task. The call may be either synchronous or asynchronous. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Make rpc_ping() staticTrond Myklebust2007-07-10

* SUNRPC: Fix races in rpcauth_createTrond Myklebust2007-07-10
| | | | | | See the FIXME: auth_flavors[] really needs a lock and module refcounting. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Fix a memory leak in gss_create()Trond Myklebust2007-07-10
| | | | | | | Fix a memory leak in gss_create() whereby the rpc credcache was not being freed if the rpc_mkpipe() call failed. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Fix a typo in unx_create()Trond Myklebust2007-07-10
| | | | | | | We want to set the unix_cred_cache.nextgc on the first call to unx_create(), which should be when unix_auth.au_count === 1 Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Fix a memory leak in the auth credcache codeTrond Myklebust2007-07-10
| | | | | | | | | | | | | | The leak only affects the RPCSEC_GSS caches, since they are the only ones that are dynamically allocated... Rename the existing rpcauth_free_credcache() to rpcauth_clear_credcache() in order to better describe its role, then add a new function rpcauth_destroy_credcache() that actually frees the cache in addition to clearing it out. Also move the call to destroy the credcache in gss_destroy() to come before the rpc upcall pipe is unlinked. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Add a field to track the number of kernel users of an rpc_pipeTrond Myklebust2007-07-10
| | | | | | This allows us to correctly deduce when we need to remove the pipe. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Clean up rpc_pipefs.Trond Myklebust2007-07-10
| | | | | | | | | | Add a dentry_ops with a d_delete() method in order to ensure that dentries are removed as soon as the last reference is gone. Clean up rpc_depopulate() so that it only removes files that were created via rpc_populate(). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Enable non-exclusive create in rpc_mkpipe()Trond Myklebust2007-07-10

* SUNRPC: Add a downcall queue to struct rpc_inodeTrond Myklebust2007-07-10
| | | | | | | | Currently, the downcall queue is tied to the struct gss_auth, which means that different RPCSEC_GSS pseudoflavours must use different upcall pipes. Add a list to struct rpc_inode that can be used instead. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Always match an upcall message in gss_pipe_downcall()Trond Myklebust2007-07-10
| | | | | | | | | | | | It used to be possible for an rpc.gssd daemon to stuff the RPC credential cache for any rpc client simply by creating RPCSEC_GSS contexts and then doing downcalls. In practice, no daemons ever made use of this feature. Remove this feature now, since it will be impossible to figure out which mechanism a given context actually matches if we enable more than one gss mechanism to use the same upcall pipe. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Remove the gss_auth spinlockTrond Myklebust2007-07-10
| | | | | | We're just as well off using the inode spinlock instead. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Add a backpointer from the struct rpc_cred to the rpc_authTrond Myklebust2007-07-10
| | | | | | | | Cleans up an issue whereby rpcsec_gss uses the rpc_clnt->cl_auth. If we want to be able to add several rpc_auths to a single rpc_clnt, then this abuse must go. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: fix hang due to eventd deadlock...Trond Myklebust2007-07-10
| | | | | | | | | | | | | | | | | | | | | | | | Brian Behlendorf writes: The root cause of the NFS hang we were observing appears to be a rare deadlock between the kernel provided usermodehelper API and the linux NFS client. The deadlock can arise because both of these services use the generic linux work queues. The usermodehelper API run the specified user application in the context of the work queue. And NFS submits both cleanup and reconnect work to the generic work queue for handling. Normally this is fine but a deadlock can result in the following situation. - NFS client is in a disconnected state - [events/0] runs a usermodehelper app with an NFS dependent operation, this triggers an NFS reconnect. - NFS reconnect happens to be submitted to [events/0] work queue. - Deadlock, the [events/0] work queue will never process the reconnect because it is blocked on the previous NFS dependent operation which will not complete.` The solution is simply to run reconnect requests on rpciod.

* SUNRPC: Make create_client() take a reference to the rpciod workqueueTrond Myklebust2007-07-10
| | | | | | | Ensures that an rpc_client always has the possibility to send asynchronous RPC calls. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Optimise rpciod_up()Trond Myklebust2007-07-10
| | | | | | | | Instead of taking the mutex every time we just need to increment/decrement rpciod_users, we can optmise by using atomic_inc_not_zero and atomic_dec_and_test. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* SUNRPC: Remove rpc_clnt->cl_countTrond Myklebust2007-07-10
| | | | | | | | | | | | The kref now does most of what cl_count + cl_user used to do. The only remaining role for cl_count is to tell us if we are in a 'shutdown' phase. We can provide that information using a single bit field instead of a full atomic counter. Also rename rpc_destroy_client() to rpc_close_client(), which reflects better what its role is these days.

* SUNRPC: Kill rpc_clnt->cl_deadTrond Myklebust2007-07-10
