* SUNRPC: soft connect semantics for UDPChuck Lever2009-12-03
| | | | | | | | Introduce soft connect behavior for UDP transports. In this case, a major timeout returns ETIMEDOUT instead of EIO. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Use soft connect semantics when performing RPC pingChuck Lever2009-12-03
| | | | | | | | | | | | | | | | | | | Currently, if a remote RPC service is unreachable, an RPC ping will hang until the underlying transport connect attempt times out. A more desirable behavior might be to have the ping fail immediately so upper layers can recover appropriately. In the case of an NFS mount, for instance, this would mean the mount(2) system call could fail immediately if the server isn't listening, rather than hanging uninterruptibly for more than 3 minutes. Change rpc_ping() so that it fails immediately for connection-oriented transports. rpc_create() will then fail immediately for such transports if an RPC ping was requested.

* SUNRPC: Use soft connects for autobinding over TCPChuck Lever2009-12-03
| | | | | | | | | | | | | | | | | | | | | | | | Autobinding is handled by the rpciod process, not in user processes that are generating regular RPC requests. Thus autobinding is usually not affected by signals targetting user processes, such as KILL or timer expiration events. In addition, an RPC request generated by a user process that has RPC_TASK_SOFTCONN set and needs to perform an autobind will hang if the remote rpcbind service is not available. For rpcbind queries on connection-oriented transports, let's use the new soft connect semantic to return control to the user's process quickly, if the kernel's rpcbind client can't connect to the remote rpcbind service. Logic is introduced in call_bind_status() to handle connection errors that occurred during an asynchronous rpcbind query. The logic abandons the rpcbind query if the RPC request has SOFTCONN set, and retries after a few seconds in the normal case.

* SUNRPC: Use TCP for local rpcbind upcallsChuck Lever2009-12-03
| | | | | | | | Use TCP with the soft connect semantic for local rpcbind upcalls so the kernel can detect immediately if the local rpcbind daemon is not running. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
* SUNRPC: Use a cached RPC client and transport for rpcbind upcallsChuck Lever2009-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel's rpcbind client creates and deletes an rpc_clnt and its underlying transport socket for every upcall to the local rpcbind daemon. When starting a typical NFS server on IPv4 and IPv6, the NFS service itself does three upcalls (one per version) times two upcalls (one per transport) times two upcalls (one per address family), making 12, plus another one for the initial call to unregister previous NFS services. Starting the NLM service adds an additional 13 upcalls, for similar reasons. (Currently the NFS service doesn't start IPv6 listeners, but it will soon enough). Instead, let's create an rpc_clnt for rpcbind upcalls during the first local rpcbind query, and cache it. This saves the overhead of creating and destroying an rpc_clnt and a socket for every upcall. The new logic also prevents the kernel from attempting an RPCB_SET or RPCB_UNSET if it knows from the start that the local portmapper does not support rpcbind protocol version 4. This will cut down on the number of rpcbind upcalls in legacy environments. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
* SUNRPC: Simplify synopsis of rpcb_local_clnt()Chuck Lever2009-12-03

* SUNRPC: Allow RPCs to fail quickly if the server is unreachableChuck Lever2009-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel sometimes makes RPC calls to services that aren't running. Because the kernel's RPC client always assumes the hard retry semantic when reconnecting a connection-oriented RPC transport, the underlying reconnect logic takes a long while to time out, even though the remote may have responded immediately with ECONNREFUSED. In certain cases, like upcalls to our local rpcbind daemon, or for NFS mount requests, we'd like the kernel to fail immediately if the remote service isn't reachable. This allows another transport to be tried immediately, or the pending request can be abandoned quickly. Introduce a per-request flag which controls how call_transmit_status() behaves when request transmission fails because the server cannot be reached. We don't want soft connection semantics to apply to other errors. The default case of the switch statement in call_transmit_status() no longer falls through; the fall through code is copied to the default case, and a "break;" is added. The transport's connection re-establishment timeout is also ignored for such requests. We want the request to fail immediately, so the reconnect delay is skipped. Additionally, we don't want a connect failure here to further increase the reconnect timeout value, since this request will not be retried.

* SUNRPC: Check explicitly for tk_status == 0 in call_transmit_status()Chuck Lever2009-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | The success case, where task->tk_status == 0, is by far the most frequent case in call_transmit_status(). The default: arm of the switch statement in call_transmit_status() handles the 0 case. default: was moved close to the top of the switch statement in call_transmit_status() under the theory that the compiler places object code for the earliest arms of a switch statement first, making the CPU do less work. The default: arm of a switch statement, however, is executed only after all the other cases have been checked. Even if the compiler rearranges the object code, the default: arm is the "last resort", meaning all of the other cases have been explicitly exhausted. That makes the current arrangement about as inefficient as it gets for the common case. To fix this, add an explicit check for zero before the switch statement. That forces the compiler to do the zero check first, no matter what optimizations it might try to do to the switch statement.

* NFS: Revert default r/wsize behaviorChuck Lever2009-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the "rsize=" or "wsize=" mount options are not specified, text-based mounts have slightly different behavior than legacy binary mounts. Text-based mounts use the smaller of the server's maximum and the client's maximum, but binary mounts use the smaller of the server's _preferred_ size and the client's maximum. This difference is actually pretty subtle. Most servers advertise the same value as their maximum and their preferred transfer size, so the end result is the same in most cases. The reason for this difference is that for text-based mounts, if r/wsize are not specified, they are set to the largest value supported by the client. For legacy mounts, the values are set to zero if these options are not specified. nfs_server_set_fsinfo() can negotiate the transfer size defaults correctly in any case. There's no need to specify any particular value as default in the text-based option parsing logic. Note that nfs4 doesn't use nfs_server_set_fsinfo(), but the mount.nfs4 command does set rsize and wsize to 0 if the user didn't specify these options. So, make the same change for text-based NFSv4 mounts. Thanks to James Pearson <james-p@moving-picture.com> for reporting and diagnosing the problem.

* NFS: convert proto= option to use netids rather than a protonameJeff Layton2009-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Solaris uses netids as values for the proto= option, so that when someone specifies "tcp6" they get traffic over TCP + IPv6. Until recently, this has never really been an issue for Linux since it didn't support NFS over IPv6. The netid and the protocol name were generally always the same (modulo any strange configuration in /etc/netconfig). The solaris manpage documents their proto= option as: proto= _netid_ | rdma This patch is intended to bring Linux closer to how the Solaris proto= option works, by declaring a static netid mapping in the kernel and converting the proto= and mountproto= options to follow it and display the proper values in /proc/mounts. Much of this functionality will need to be provided by a userspace mount.nfs patch. Chuck Lever has a patch to change mount.nfs in the same way. In principle, we could do *all* of this in userspace but that would mean that the options in /proc/mounts may not match the options used by userspace. The alternative to the static mapping here is to add a mechanism to upcall to userspace for netid's. I'm not opposed to that option, but it'll probably mean more overhead (and quite a bit more code). Rather than shoot for that at first, I figured it was probably better to start simply. Comments welcome.

But in fact it is not needed in mainline because the earlier commit dd00a99e7a fixes the same problem in a better way. Further, this commit introduces a bug in the way it interacts with the automatic read-error-correction. If, after a read error is successfully corrected, the same disk is chosen to re-read - the re-read won't be attempted but an error will be returned instead. After reverting that commit, there is the possibility that a read error on a read-only array (where read errors cannot be corrected as that requires a write) will repeatedly read the same device and continue to get an error. So in the "Array is readonly" case, fail the drive immediately on a read error. Signed-off-by: NeilBrown <neilb@suse.de> Cc: stable@kernel.org

An objdump on such a kernel module gives: Sections: Idx Name Size VMA LMA File off Algn 0 .note.gnu.build-id 00000024 00000000 00000000 00000034 2**2 CONTENTS, ALLOC, LOAD, READONLY, DATA 1 .text 00000000 00000000 00000000 00000058 2**0 CONTENTS, ALLOC, LOAD, READONLY, CODE 2 .text.ac97_bus_match 0000001c 00000000 00000000 00000058 2**2 CONTENTS, ALLOC, LOAD, READONLY, CODE 3 .text 00000000 00000000 00000000 000000d4 2**0 CONTENTS, ALLOC, LOAD, READONLY, CODE ...

The function translating rtc_time to register values assumes tm_year to be years since first christmas, though, and we end up storing 0 or 1 in the CCR_Y2K register, which the hardware does not refuse to do. A subsequent probing of the clock fails due to the invalid value range in the register, though. [ And if it didn't, reading the clock would yield a bogus year because the function translating registers to tm_year is assuming a register value of 19 or 20. ] This fixes the conversion from years since 1900 in tm_year to the corresponding CCR_Y2K value of 19 or 20.
