* SUNRPC: Move the bound cred to struct rpc_rqstTrond Myklebust2010-08-0412-96/+92
| | | | | | | | This will allow us to save the original generic cred in rpc_message, so that if we migrate from one server to another, we can generate a new bound cred without having to punt back to the NFS layer. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* SUNRPC: Move remaining RPC client related task initialisation into clnt.cTrond Myklebust2010-08-043-73/+89
| | | | | | | | | | | Now that rpc_run_task() is the sole entry point for RPC calls, we can move the remaining rpc_client-related initialisation of struct rpc_task from sched.c into clnt.c. Also move rpc_killall_tasks() into the same file, since that too is relative to the rpc_clnt. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Ensure that rpc_exit() always wakes up a sleeping taskTrond Myklebust2010-08-042-17/+10
| | | | | | | | | Make rpc_exit() non-inline, and ensure that it always wakes up a task that has been queued. Kill off the now unused rpc_wake_up_task(). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Make the credential cache hashtable size configurableTrond Myklebust2010-08-042-13/+56
| | | | | | | | | This patch allows the user to configure the credential cache hashtable size using a new module parameter: auth_hashtable_size When set, this parameter will be rounded up to the nearest power of two, with a maximum allowed value of 1024 elements.

* NFS: Fix the NFS users of rpc_restart_call()Trond Myklebust2010-08-032-7/+4
| | | | | | | Fix up those functions that depend on knowing whether or not rpc_restart_call is successful or not. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: The function rpc_restart_call() should return success/failureTrond Myklebust2010-08-032-7/+8
| | | | | | | | | | Both rpc_restart_call_prepare() and rpc_restart_call() test for the RPC_TASK_KILLED flag, and fail to restart the RPC call if that flag is set. This patch allows callers to know whether or not the restart was successful, so that they can perform cleanups etc in case of failure. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Get rid of the bogus RPC_ASSASSINATED(task) checksTrond Myklebust2010-08-031-10/+0
| | | | | | | There is no real reason to have RPC_ASSASSINATED() checks in the NFS code. As far as it is concerned, this is just an RPC error... Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* NFSv4.1: Handle NFS4ERR_DELAY on SEQUENCE correctlyTrond Myklebust2010-08-031-30/+62
| | | | | | | | | | | In RFC5661, an NFS4ERR_DELAY error on a SEQUENCE operation has the special meaning that the server is not finished processing the request. In this case we want to just retry the request without touching the slot. Also fix a bug whereby we would fail to update the sequence id if the server returned any error other than NFS_OK/NFS4ERR_DELAY. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFS: nfs_rename() should not have to flush out writebacksTrond Myklebust2010-08-031-9/+0
| | | | | | | | We don't really support nfs servers that invalidate the file handle after a rename, so precautions such as flushing out dirty data before renaming the file are superfluous. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* NFS: Fix up the fsync codeTrond Myklebust2010-08-031-30/+21
| | | | | | | | Christoph points out that the VFS will always flush out data before calling nfs_fsync(), so we can dispense with a full call to nfs_wb_all(), and replace that with a simpler call to nfs_commit_inode(). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* NFSv4.1: Simplify nfs41_sequence_done()Trond Myklebust2010-06-221-14/+12
| | | | | | | | | Nobody uses the rpc_status parameter. It is not obvious why we need the struct nfs_client argument either, when we already have that information in the session. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4.1: Clean up nfs4_setup_sequenceTrond Myklebust2010-06-221-6/+1
| | | | | | | | | | | Firstly, there is little point in first zeroing out the entire struct nfs4_sequence_res, and then initialising all fields save one. Just initialise the last field to zero... Secondly, nfs41_setup_sequence() has only 2 possible return values: 0, or -EAGAIN, so there is no 'terminate rpc task' case. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | | | | | | | | | | | If the attempt to read the calldir fails, then instead of storing the read bytes, we currently discard them. This leads to a garbage final result when upon re-entry to the same routine, we read the remaining bytes. Fixes the regression in bugzilla number 16213.

This behavior is different then the non-accelerated path and for pkts over a bonded vlan. For example, vlanx -> bond0 -> ethx will be dropped in the vlan path and not delivered to any packet handlers at all. However, bond0 -> vlanx -> ethx and bond0 -> ethx will be delivered to handlers that match the exact dev, because the VLAN path checks the real_dev which is not a slave and netif_recv_skb() doesn't drop frames but only delivers them to exact matches. This patch adds a sk_buff flag which is used for tagging skbs that would previously been dropped and allows the skb to continue to skb_netif_recv(). Here we add logic to check for the deliver_no_wcard flag and if it is set only deliver to handlers that match exactly. This makes both paths above consistent and gives pkt handlers a way to identify skbs that come from inactive slaves. Without this patch in some configurations skbs will be delivered to handlers with exact matches and in others be dropped out right in the vlan path. I have tested the following 4 configurations in failover modes and load balancing modes. # bond0 -> ethx # vlanx -> bond0 -> ethx # bond0 -> vlanx -> ethx # bond0 -> ethx | vlanx -> -- Signed-off-by: John Fastabend <john.r.fastabend@intel.com> Signed-off-by: David S.
