* nfs: count correct array for mnt3_counts array sizeEryu Guan2017-07-211-1/+1
| | | | | | | | | | | | Array size of mnt3_counts should be the size of array mnt3_procedures, not mnt_procedures, though they're same in size right now. Found this by code inspection.

| | | | | | | | | | | p_count is the only writeable memeber of struct rpc_procinfo, which is a good candidate to be const-ified as it contains function pointers. This patch moves it into out out struct rpc_procinfo, and into a separate writable array that is pointed to by struct rpc_version and indexed by p_statidx.

* nfsv3: Make v3 mounts fail with ETIMEDOUTs instead EIO on mountd timeoutsScott Mayhew2012-10-311-1/+1
| | | | | | | | | | | | | | | | In very busy v3 environment, rpc.mountd can respond to the NULL procedure but not the MNT procedure in a timely manner causing the MNT procedure to time out. The problem is the mount system call returns EIO which causes the mount to fail, instead of ETIMEDOUT, which would cause the mount to be retried. This patch sets the RPC_TASK_SOFT|RPC_TASK_TIMEOUT flags to the rpc_call_sync() call in nfs_mount() which causes ETIMEDOUT to be returned on timed out connections.

Then, instead of a status, zero is unconditionally returned. Update the mount client XDR encoders to behave this way. To finish the update, use the new-style be32_to_cpup() and cpu_to_be32() macros, and compute the buffer sizes using raw integers instead of sizeof().

* NFS: Fix panic after nfs_umount()Chuck Lever2010-12-101-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | After a few unsuccessful NFS mount attempts in which the client and server cannot agree on an authentication flavor both support, the client panics. nfs_umount() is invoked in the kernel in this case. Turns out nfs_umount()'s UMNT RPC invocation causes the RPC client to write off the end of the rpc_clnt's iostat array. This is because the mount client's nrprocs field is initialized with the count of defined procedures (two: MNT and UMNT), rather than the size of the client's proc array (four). The fix is to use the same initialization technique used by most other upper layer clients in the kernel. Introduced by commit 0b524123, which failed to update nrprocs when support was added for UMNT in the kernel.

| * NFS: Add ability to send MOUNTPROC_UMNT to the kernel's mountd clientChuck Lever2009-08-091-0/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After certain failure modes of an NFS mount, an NFS client should send a MOUNTPROC_UMNT request to remove the just-added mount entry from the server's mount table. While no-one should rely on the accuracy of the server's mount table, sending a UMNT is simply being a good internet neighbor. Since NFS mount processing is handled in the kernel now, we will need a function in the kernel's mountd client that can post a MOUNTRPC_UMNT request, in order to handle these failure modes.

* NFS: Add separate mountd status code decoders for each mountd versionChuck Lever2009-06-181-0/+116
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce data structures and xdr_stream-based decoding functions for unmarshalling mountd status codes properly. Mountd version 3 uses specific standard error return codes that are not errno values and not NFS3ERR_ values. These have a well-defined standard mapping to local errno values. Introduce data structures and a decoder function that map these status codes to local errno values properly. This is new functionality (but not used yet). Version 1 mountd status values are defined by RFC 1094 as UNIX error values (errno values). Errno values on heterogeneous systems do not necessarily match each other. To avoid exposing possibly incorrect errno values to upper layers, the current XDR decoder converts all non-zero MNT version 1 status codes to -EACCES. The OpenGroup XNFS standard provides a mapping similar to but smaller than the version 3 error codes. Implement a decoder that uses the XNFS error codes, replacing the current decoder. For both mountd protocol versions, map unrecognized errors to -EACCES. Finally we introduce a replacement data structure for mnt_fhstatus at this time, which is used by the new XDR decoders. In addition to documenting that the status value returned by the XDR decoders is always an errno, this new structure will be expanded in subsequent patches.

| | | | | | | | | | | | | | | | | | | | This patch fixes a regression that was introduced by the string based mounts. nfs_mount() statically returns -EACCES for every error returned by the remote mounted. This is incorrect because -EACCES is an non-fatal error to the mount.nfs command. This error causes mount.nfs to retry the mount even in the case when the exported directory does not exist.

A little instrumentation demonstrated that in fact rpc_malloc was never allocating the buffer from the mempool, but almost always called kmalloc. To compute the size of the RPC buffer more precisely, split p_bufsiz into two fields; one for the argument size, and one for the result size. Then, compute the sum of the exact call and reply header sizes, and split the RPC buffer precisely between the two. That should keep almost all RPC buffers within the 2KiB buffer mempool limit.
