* nfsd: add get_uint for u32'sJ. Bruce Fields2012-11-171-0/+16
| | | | | | | | | | | | commit a007c4c3e943ecc054a806c259d95420a188754b upstream. I don't think there's a practical difference for the range of values these interfaces should see, but it would be safer to be unambiguous. Signed-off-by: J.

|/ | | | | | | | | | | | | | | Commit b0b0c0a26e84 "nfsd: add proc file listing kernel's gss_krb5 enctypes" added an nunnecessary dependency of nfsd on the auth_rpcgss module.

* | | SUNRPC: Support for RPC over AF_LOCAL transportsChuck Lever2011-05-272-1/+3
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TI-RPC introduces the capability of performing RPC over AF_LOCAL sockets. It uses this mainly for registering and unregistering local RPC services securely with the local rpcbind, but we could also conceivably use it as a generic upcall mechanism. This patch provides a client-side only implementation for the moment. We might also consider a server-side implementation to provide AF_LOCAL access to NLM (for statd downcalls, and such like). Autobinding is not supported on kernel AF_LOCAL transports at this time. Kernel ULPs must specify the pathname of the remote endpoint when an AF_LOCAL transport is created. rpcbind supports registering services available via AF_LOCAL, so the kernel could handle it with some adjustment to ->rpcbind and ->set_port. But we don't need this feature for doing upcalls via well-known named sockets. This has not been tested with ULPs that move a substantial amount of data. Thus, I can't attest to how robust the write_space and congestion management logic is. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | | | | | | | | | | | | | | | | | | | | | | | On occasion, it is useful for the NFS layer to distinguish between soft timeouts and other EIO errors due to (say) encoding errors, or authentication errors.

* SUNRPC: Close a race in __rpc_wait_for_completion_task()Trond Myklebust2011-03-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Although they run as rpciod background tasks, under normal operation (i.e. no SIGKILL), functions like nfs_sillyrename(), nfs4_proc_unlck() and nfs4_do_close() want to be fully synchronous. This means that when we exit, we want all references to the rpc_task to be gone, and we want any dentry references etc. held by that task to be released. For this reason these functions call __rpc_wait_for_completion_task(), followed by rpc_put_task() in the expectation that the latter will be releasing the last reference to the rpc_task, and thus ensuring that the callback_ops->rpc_release() has been called synchronously. This patch fixes a race which exists due to the fact that rpciod calls rpc_complete_task() (in order to wake up the callers of __rpc_wait_for_completion_task()) and then subsequently calls rpc_put_task() without ensuring that these two steps are done atomically. In order to avoid adding new spin locks, the patch uses the existing waitqueue spin lock to order the rpc_task reference count releases between the waiting process and rpciod. The common case where nobody is waiting for completion is optimised for by checking if the RPC_TASK_ASYNC flag is cleared and/or if the rpc_task reference count is 1: in those cases we drop trying to grab the spin lock, and immediately free up the rpc_task. Those few processes that need to put the rpc_task from inside an asynchronous context and that do not care about ordering are given a new helper: rpc_put_task_async().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we use -EAGAIN returns to determine when to drop a deferred request. On its own, that is error-prone, as it makes us treat -EAGAIN returns from other functions specially to prevent inadvertent dropping. So, use a flag on the request instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The xpt_pool field is only used for reporting BUGs. And it isn't used correctly. In particular, when it is cleared in svc_xprt_received before XPT_BUSY is cleared, there is no guarantee that either the compiler or the CPU might not re-order to two assignments, just setting xpt_pool to NULL after XPT_BUSY is cleared. If a different cpu were running svc_xprt_enqueue at this moment, it might see XPT_BUSY clear and then xpt_pool non-NULL, and so BUG. This could be fixed by calling smp_mb__before_clear_bit() before the clear_bit. However as xpt_pool isn't really used, it seems safest to simply remove xpt_pool. Another alternate would be to change the clear_bit to clear_bit_unlock, and the test_and_set_bit to test_and_set_bit_lock. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: J.

Refactor nfs_find_client to use minorversion specific means to locate the correct nfs_client structure. In the NFS layer, V4.0 clients are found using the callback_ident field in the CB_COMPOUND header. V4.1 clients are found using the sessionID in the CB_SEQUENCE operation which is also compared against the sessionID associated with the back channel thread after a successful CREATE_SESSION. Each of these methods finds the one an only nfs_client associated with the incoming callback request - so nfs_find_client_next is not needed. In the RPC layer, the pg_authenticate call needs to find the nfs_client. For the v4.0 callback service, the callback identifier has not been decoded so a search by address, version, and minorversion is used. The sessionid for the sessions based callback service has (usually) not been set for the pg_authenticate on a CB_NULL call which can be sent prior to the return of a CREATE_SESSION call, so the sessionid associated with the back channel thread is not used to find the client in pg_authenticate for CB_NULL calls. Pass the referenced nfs_client to each CB_COMPOUND operation being proceesed via the new cb_process_state structure. The reference is held across cb_compound processing. Use the new cb_process_state struct to move the NFS4ERR_RETRY_UNCACHED_REP processing from process_op into nfs4_callback_sequence where it belongs.

| * nfsd: provide callbacks on svc_xprt deletionJ. Bruce Fields2010-10-011-0/+25
| | | | | | | | | | | | | | | | NFSv4.1 needs warning when a client tcp connection goes down, if that connection is being used as a backchannel, so that it can warn the client that it has lost the backchannel connection. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
| * nfsd4: remove spkm3J. Bruce Fields2010-10-011-55/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unfortunately, spkm3 never got very far; while interoperability with one other implementation was demonstrated at some point, problems were found with the spec that were deemed not worth fixing. The kernel code is useless on its own without nfs-utils patches which were never merged into nfs-utils, and were only ever available from citi.umich.edu. They appear not to have been updated since 2005. Therefore it seems safe to assume that this code has no users, and never will. Signed-off-by: J. Bruce Fields <bfields@redhat.com>
