2012-03-20NFSD: Fix nfs4_verifier memory alignmentChuck Lever4-28/+31
Clean up due to code review. The nfs4_verifier's data field is not guaranteed to be u32-aligned. Casting an array of chars to a u32 * is considered generally hazardous. We can fix most of this by using a __be32 array to generate the verifier's contents and then byte-copying it into the verifier field. However, there is one spot where there is a backwards compatibility constraint: the do_nfsd_create() call expects a verifier which is 32-bit aligned. Fix this spot by forcing the alignment of the create verifier in the nfsd4_open args structure. Also, sizeof(nfs4_verifer) is the size of the in-core verifier data structure, but NFS4_VERIFIER_SIZE is the number of octets in an XDR'd verifier. The two are not interchangeable, even if they happen to have the same value. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com>

2012-03-19nfsd: merge cookie collision fixes from ext4 treeJ. Bruce Fields6-58/+205
These changes fix readdir loops on ext4 filesystems with dir_index turned on. I'm pulling them from Ted's tree as I'd like to give them some extra nfsd testing, and expect to be applying (potentially conflicting) patches to the same code before the next merge window.

2012-03-19nfsd: vfs_llseek() with 32 or 64 bit offsets (hashes)Bernd Schubert2-2/+15
Use 32-bit or 64-bit llseek() hashes for directory offsets depending on the NFS version. NFSv2 gets 32-bit hashes only. NOTE: This patch got rather complex as Christoph asked to set the filp->f_mode flag in the open call or immediatly after dentry_open() in nfsd_open() to avoid races. Personally I still do not see a reason for that and in my opinion FMODE_32BITHASH/FMODE_64BITHASH flags could be set nfsd_readdir(), as it follows directly after nfsd_open() without a chance of races.

2012-03-19ext4: return 32/64-bit dir name hash according to usage typeFan Yong3-48/+176
Traditionally ext2/3/4 has returned a 32-bit hash value from llseek() to appease NFSv2, which can only handle a 32-bit cookie for seekdir() and telldir(). However, this causes problems if there are 32-bit hash collisions, since the NFSv2 server can get stuck resending the same entries from the directory repeatedly. Allow ext4 to return a full 64-bit hash (both major and minor) for telldir to decrease the chance of hash collisions. This still needs integration on the NFS side.

2012-03-10nfsd4: make sure set CB_PATH_DOWN sequence flag setJ. Bruce Fields1-1/+1
Make sure this is set whenever there is no callback channel. If a client does not set up a callback channel at all, then it will get this flag set from the very start. That's OK, it can just ignore the flag if it doesn't care. If a client does care, I think it's better to inform it of the problem as early as possible.

2012-03-07nfsd41: free_session/free_client must be called under the client_lockBenny Halevy2-16/+32
The session client is manipulated under the client_lock hence both free_session and nfsd4_del_conns must be called under this lock. This patch adds a BUG_ON that checks this condition in the respective functions and implements the missing locks. nfsd4_{get,put}_session helpers were moved to the C file that uses them so to prevent use from external files and an unlocked version of nfsd4_put_session is provided for external use from nfs4xdr.c Signed-off-by: Benny Halevy <bhalevy@tonian.com> Signed-off-by: J.

When a 4.1 client asks for a delegation and the server returns none op_delegate_type is set to NFS4_OPEN_DELEGATE_NONE_EXT and op_why_no_deleg is set to either WND4_CONTENTION or WND4_RESOURCE. Or, if the client sent a NFS4_SHARE_WANT_CANCEL (which it is not supposed to ever do until our server supports delegations signaling), op_why_no_deleg is set to WND4_CANCELLED.

2012-03-07nfsd4: purge stable client records with insufficient stateJ. Bruce Fields1-1/+3
To escape having your stable storage record purged at the end of the grace period, it's not sufficient to simply have performed a setclientid_confirm; you also need to meet the same requirements as someone creating a new record: either you should have done an open or open reclaim (in the 4.0 case) or a reclaim_complete (in the 4.1 case).

We set cl_firststate when we first decide that a client will be permitted to reclaim state on next boot. This happens: - for new 4.0 clients, when they confirm their first open - for returning 4.0 clients, when they reclaim their first open - for 4.1+ clients, when they perform reclaim_complete We also use cl_firststate to decide whether a reclaim_complete has already been performed, in the 4.1+ case. We were setting it on 4.1 open reclaims, which caused spurious COMPLETE_ALREADY errors on RECLAIM_COMPLETE from an nfs4.1 client with anything to reclaim.

This resolution takes the semantics from commit f2933e86ad93, and just makes mtd_block_isbad() return zero (false) if the 'block_isbad' function is NULL. But that also means that now "mtd_can_have_bb()" always returns 0. Now, "mtd_block_markbad()" will obviously return an error if the low-level driver doesn't support bad blocks, so this is somewhat non-symmetric, but it actually makes sense if a NULL "block_isbad" function is considered to mean "I assume that all my blocks are always good".

1) Setting link attributes can modify the size of the attributes that would be reported on a subsequent getlink netlink operation, therefore min_ifinfo_dump_size needs to be adjusted. From Stefan Gula. 2) Resegmentation of TSO frames while trimming can violate invariants expected by callers, namely that the number of segments can only stay the same or decrease, never increase. If MSS changes, however, we can trim data but then end up with more segments. Fix this by only segmenting to the MSS already recorded in the SKB. That's the simplest fix for now and if we want to get more fancy in the future that's a more involved change. This probably explains some retransmit counter inaccuracies.
