2009-12-17Revert "fix mismerge with Trond's stuff (create_mnt_ns() export is gone now)"Linus Torvalds1-0/+8
This reverts commit e9496ff46a20a8592fdc7bdaaf41b45eb808d310. Quoth Al: "it's dependent on a lot of other stuff not currently in mainline and badly broken with current fs/namespace.c. Sorry, badly out-of-order cherry-pick from old queue. PS: there's a large pending series reworking the refcounting and lifetime rules for vfsmounts that will, among other things, allow to rip a subtree away _without_ dissolving connections in it, to be garbage-collected when all active references are gone. It's considerably saner wrt "is the subtree busy" logics, but it's nowhere near being ready for merge at the moment; this changeset is one of the things becoming possible with that sucker, but it certainly shouldn't have been picked during this cycle.

2009-12-15NFSv4: Fix a regression in the NFSv4 state managerTrond Myklebust1-3/+2
Commit 5601a00d671fe89f9b087513244abcd08ad67e7d (nfs: run state manager in privileged mode) introduces a regression in the NFSv4 code when compiled with CONFIG_NFS_V4_1. The calls to nfs4_end_drain_session() from the main loop in nfs4_state_manager() Oops due to the lack of an NFSv4.1 session when running NFSv4.0. The fix is to move those two calls back into nfs41_init_clientid() and nfs4_reset_session(). The calls to nfs4_end_drain_session() that remain inside nfs4_state_manager() are safe, since the NFSv4.0 code will never set the NFS4CLNT_SESSION_DRAINING bit.

2009-12-15NFSv4: Release the sequence id before restarting a CLOSE rpc callTrond Myklebust3-6/+11
If the CLOSE or OPEN_DOWNGRADE call triggers a state recovery, and has to be resent, then we must release the seqid. Otherwise the open recovery will wait for the close to finish, which causes a deadlock. This is mainly a NFSv4.1 problem, although it can theoretically happen with NFSv4.0 too, in a OPEN_DOWNGRADE situation. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2009-12-10vfs: Implement proper O_SYNC semanticsChristoph Hellwig2-3/+3
While Linux provided an O_SYNC flag basically since day 1, it took until Linux 2.4.0-test12pre2 to actually get it implemented for filesystems, since that day we had generic_osync_around with only minor changes and the great "For now, when the user asks for O_SYNC, we'll actually give O_DSYNC" comment. This patch intends to actually give us real O_SYNC semantics in addition to the O_DSYNC semantics. After Jan's O_SYNC patches which are required before this patch it's actually surprisingly simple, we just need to figure out when to set the datasync flag to vfs_fsync_range and when not. This patch renames the existing O_SYNC flag to O_DSYNC while keeping it's numerical value to keep binary compatibility, and adds a new real O_SYNC flag. To guarantee backwards compatiblity it is defined as expanding to both the O_DSYNC and the new additional binary flag (__O_SYNC) to make sure we are backwards-compatible when compiled against the new headers. This also means that all places that don't care about the differences can just check O_DSYNC and get the right behaviour for O_SYNC, too - only places that actuall care need to check __O_SYNC in addition. Drivers and network filesystems have been updated in a fail safe way to always do the full sync magic if O_DSYNC is set. The few places setting O_SYNC for lower layers are kept that way for now to stay failsafe. We enforce that O_DSYNC is set when __O_SYNC is set early in the open path to make sure we always get these sane options. Note that parisc really screwed up their headers as they already define a O_DSYNC that has always been a no-op. We try to repair it by using it for the new O_DSYNC and redefinining O_SYNC to send both the traditional O_SYNC numerical value _and_ the O_DSYNC one.

2009-12-08nfs41: Invoke RECLAIM_COMPLETE on all new client idsRicardo Labiaga1-3/+4
The NFSv4.1 spec indicates RECLAIM_COMPLETE is to be issued whenever a client establishes a new client id, not only after detecting the server has rebooted. Set the NFS4CLNT_RECLAIM_REBOOT bit after every new client id has been established. This enables us to issue RECLAIM_COMPLETE during the wrap up of the NFS4CLNT_RECLAIM_REBOOT state.

2009-12-08NFSv41: Fix a potential state leakage when restarting nfs4_close_prepareTrond Myklebust1-17/+35
Currently, if the call to nfs4_setup_sequence() in nfs4_close_prepare fails, any later retries will fail to launch an RPC call, due to the fact that the &state->flags will have been cleared. Ditto if nfs4_close_done() triggers a call to the NFSv4.1 version of nfs_restart_rpc(). We therefore move the actual clearing of the state->flags to nfs4_close_done(), when we know that the RPC call was successful. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

This patch invokes RECLAIM_COMPLETE after the client is done reclaiming state. There are interpretations of the spec that suggest that RECLAIM_COMPLETE should also be issued after a new clientid has been obtained from the server and even if there is no state to reclaim.

Implements RECLAIM_COMPLETE as an asynchronous RPC. NFS4ERR_DELAY is retried, NFS4ERR_DEADSESSION invokes the error handling but does not result in a retry, since we don't want to have a lingering RECLAIM_COMPLETE call sent in the middle of a possible new state recovery cycle. If a session reset occurs, a new wave of reclaim operations will follow, containing their own RECLAIM_COMPLETE call. We don't want a retry to get on the way of recovery by incorrectly indicating to the server that we're done reclaiming state. A subsequent patch invokes the functionality.
