Call nfs_can_coalesce_requests for every request, even the first one. This is needed for future patches to give pg_test a way to inform add_request to reduce the size of the request. Now @prev can be null in nfs_can_coalesce_requests and pg_test functions.

This is a step toward allowing pg_test to inform the the coalescing code to reduce the size of requests so they may fit in whatever scheme the pg_test callback wants to define. For now, just return the size of the request if there is space, or 0 if there is not. This shouldn't change any behavior as it acts the same as when the pg_test functions returned bool.

cond_resched_lock(cinfo->lock) is called everywhere else while holding the cinfo->lock spinlock. Not holding this lock while calling transfer_commit_list in filelayout_recover_commit_reqs causes the BUG below. It's true that we can't hold this lock while calling pnfs_put_lseg, because that might try to lock the inode lock - which might be the same lock as cinfo->lock. To reproduce, mount a 2 DS pynfs server and run an O_DIRECT command that crosses a stripe boundary and is not page aligned, such as: dd if=/dev/zero of=/mnt/f bs=17000 count=1 oflag=direct BUG: sleeping function called from invalid context at linux/fs/nfs/nfs4filelayout.c:1161 in_atomic(): 0, irqs_disabled(): 0, pid: 27, name: kworker/0:1 2 locks held by kworker/0:1/27: #0: (events){.+.+.+}, at: [<ffffffff810501d7>] process_one_work+0x175/0x3a5 #1: ((&dreq->work)){+.+...}, at: [<ffffffff810501d7>] process_one_work+0x175/0x3a5 CPU: 0 PID: 27 Comm: kworker/0:1 Not tainted 3.13.0-rc3-branch-dros_testing+ #21 Hardware name: VMware, Inc.

Commit 4edaa308 "NFS: Use "krb5i" to establish NFSv4 state whenever possible" uses the nfs_client cl_rpcclient for all state management operations, and will use krb5i or auth_sys with no regard to the mount command authflavor choice. The MDS, as any NFSv4.1 mount point, uses the nfs_server rpc client for all non-state management operations with a different nfs_server for each fsid encountered traversing the mount point, each with a potentially different auth flavor. pNFS data servers are not mounted in the normal sense as there is no associated nfs_server structure. Data servers can also export multiple fsids, each with a potentially different auth flavor. Data servers need to use the same authflavor as the MDS server rpc client for non-state management operations. Populate a list of rpc clients with the MDS server rpc client auth flavor for the DS to use.

If we replay a READ or WRITE call, we should not be changing the stateid. Currently, we may end up doing so, because the stateid is only selected at xdr encode time.

If state recovery fails with an ESTALE or a ENOENT, then we shouldn't keep retrying. Instead, mark the stateid as being invalid and fail the I/O with an EIO error. For other operations such as POSIX and BSD file locking, truncate etc, fail with an EBADF to indicate that this file descriptor is no longer valid.

Currently, when an RPCSEC_GSS context has expired or is non-existent and the users (Kerberos) credentials have also expired or are non-existent, the client receives the -EKEYEXPIRED error and tries to refresh the context forever. If an application is performing I/O, or other work against the share, the application hangs, and the user is not prompted to refresh/establish their credentials. This can result in a denial of service for other users. Users are expected to manage their Kerberos credential lifetimes to mitigate this issue. Move the -EKEYEXPIRED handling into the RPC layer. Try tk_cred_retry number of times to refresh the gss_context, and then return -EACCES to the application.

We already have a mechanism for blocking LAYOUTGET by means of the plh_block_lgets counter. The only "service" that NFS_LAYOUT_DESTROYED provides at this point is to block layoutget once the layout segment list is empty, which basically means that you have to wait until the pnfs_layout_hdr is destroyed before you can do pNFS on that file again. This patch enables the reuse of the pnfs_layout_hdr if the layout segment list is empty. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

In all cases where we set NFS_LAYOUT_INVALID, we also set NFS_LAYOUT_DESTROYED. Furthermore, in all cases where we test for NFS_LAYOUT_INVALID, we should also be testing for NFS_LAYOUT_DESTROYED, since the latter means that we hold no valid layout segments.

The 'committed' field is not needed once we have put the struct nfs_page on the right list. Also correct the type of the verifier: it is not an array of __be32, but simply an 8 byte long opaque array. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

The "struct inode *inode" was only used in a dprintk, so compiling with CONFIG_SUNRPC_DEBUG off triggers a warning. To get around this, I remove the "struct inode *inode" variable and instead change the dprintk()s to use hdr->inode instead.

We reset all I/O on a disconnected data server through the pgio layer indicated by the NFS_IOHDR_REDO flag. Differentiate between on-the-wire tasks returning with an error which must call rpc_call_done and tasks woken from the data server slot_table_waitq waiting for a session slot with a status of zero which call rpc_exit in rpc_prepare and need to skip rpc_call_done.
