2009-12-10exofs: refactor exofs_i_info initialization into common helperBoaz Harrosh
There are two places that initialize inodes: exofs_iget() and exofs_new_inode() As more members of exofs_i_info that need initialization are added this code will grow. (soon) Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
2009-12-10exofs: dbg-print lessBoaz Harrosh
Iner-loops printing is converted to EXOFS_DBG2 which is #defined to nothing. It is now almost bareable to just leave debug-on. Every operation is printed once, with most relevant info (I hope). Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>

2009-12-08NFSv41: Fix a potential state leakage when restarting nfs4_close_prepareTrond Myklebust
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>

2009-12-06ext4: Fix insufficient checks in EXT4_IOC_MOVE_EXTAkira Fujita
This patch fixes three problems in the handling of the EXT4_IOC_MOVE_EXT ioctl: 1. In current EXT4_IOC_MOVE_EXT, there are read access mode checks for original and donor files, but they allow the illegal write access to donor file, since donor file is overwritten by original file data. To fix this problem, change access mode checks of original (r->r/w) and donor (r->w) files. 2. Disallow the use of donor files that have a setuid or setgid bits. 3. Call mnt_want_write() and mnt_drop_write() before and after ext4_move_extents() calling to get write access to a mount.

2009-12-08ext4: wait for log to commit when umountingJosef Bacik
There is a potential race when a transaction is committing right when the file system is being umounting. This could reduce in a race because EXT4_SB(sb)->s_group_info could be freed in ext4_put_super before the commit code calls a callback so the mballoc code can release freed blocks in the transaction, resulting in a panic trying to access the freed s_group_info.

2009-12-08ext4: Avoid data / filesystem corruption when write fails to copy dataJan Kara
When ext4_write_begin fails after allocating some blocks or generic_perform_write fails to copy data to write, we truncate blocks already instantiated beyond i_size. Although these blocks were never inside i_size, we have to truncate the pagecache of these blocks so that corresponding buffers get unmapped. Otherwise subsequent __block_prepare_write (called because we are retrying the write) will find the buffers mapped, not call ->get_block, and thus the page will be backed by already freed blocks leading to filesystem and data corruption.

2009-12-05nfs41: Invoke RECLAIM_COMPLETERicardo Labiaga
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. This tells the server that the client has no state to reclaim even if the client isn't aware the server may have rebooted.

2009-12-05nfs41: RECLAIM_COMPLETE functionalityRicardo Labiaga
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.

2009-12-05nfs41: RECLAIM_COMPLETE XDR functionalityRicardo Labiaga
XDR encoding and decoding for RECLAIM_COMPLETE. Implements the necessary encoding to indicate reclaim complete for the entire client. In the future, it can be extended to provide reclaim complete functionality for a single file system after migration.

2009-12-05nfs41: check SEQUENCE status flagAlexandros Batsakis
the server can indicate a number of error conditions by setting the appropriate bits in the SEQUENCE operation. The client re-establishes state with the server when it receives one of those, with the action depending on the specific case.

2009-12-05nfs41: V2 adjust max_rqst_sz, max_resp_sz w.r.t to rsize, wsizeAlexandros Batsakis
The v4.1 client should take into account the desired rsize, wsize when negotiating the max size in CREATE_SESSION. Accordingly, it should use rsize, wsize that are smaller than the session negotiated values.

In v4.1 the client MUST/SHOULD use the EXCLUSIVE4_1 flag instead of EXCLUSIVE4, and GUARDED when the server supports persistent sessions.
