If we return delegation before closing, we fail to do roc check during close because NFS_LAYOUT_ROC is cleared by delegreturn and it causes layouts to be still hanging around after delegreturn + close, which is a voilation against protocol.

Unlike the previous attempt, this takes into account the fact that we may be calling it from the recovery thread itself. Detect this by looking at what kind of open we're doing, and checking the state of the NFS_DELEGATION_NEED_RECLAIM if it turns out we're doing a reboot reclaim-type open.

If we have an OPEN_DOWNGRADE and CLOSE race with one another, we want to ensure that the layout is forgotten by the client, so that we start afresh with a new layoutget. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>

Trond Myklebust authored
The helper pnfs_roc() has already verified that we have no delegations, and no further open files, hence no outstanding I/O and it has marked all the return-on-close lsegs as being invalid. Furthermore, it sets the NFS_LAYOUT_RETURN bit, thus serialising the close/delegreturn with all future layoutget calls on this inode. The checks in pnfs_roc_drain() for valid layout segments are therefore redundant: those cannot exist until another layoutget completes. The other check for whether or not NFS_LAYOUT_RETURN is set, actually causes a hang, since we already know that we hold that flag. To fix, we therefore strip out all the functionality in pnfs_roc_drain() except the retrieval of the barrier state, and then rename the function accordingly.

Chuck reports seeing cases where a GETATTR that happens to race with an asynchronous WRITE is overriding the file size, despite the attribute barrier being set by the writeback code. The culprit turns out to be the check in nfs_ctime_need_update(), which sees that the ctime is newer than the cached ctime, and assumes that it is safe to override the attribute barrier. This patch removes that override, and ensures that attribute barriers are always respected. Reported-by: Chuck Lever <chuck.lever@oracle.com> Fixes: a08a8cd3 ("NFS: Add attribute update barriers to NFS writebacks") Cc: stable@vger.kernel.org # v4.0+ Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>

NFS: NFS over RDMA Client Side Changes These patches improve both client performance and scalability, most notably by increasing the maixmum allowed rsize and wsize and by increasing the number of RDMA "credits".

nfs_readdir_xdr_to_array() uses both a cache array and an array of pages, so I rename these functions to make it clearer how the code works. nfs_readdir_large_page() becomes nfs_readdir_alloc_pages() because this function has absolutely nothing to do with setting up a large page. nfs_readdir_free_pagearray() becomes nfs_readdir_free_pages() to stay consistent with the new alloc_pages() function.

This variable is initialized to NULL and is never modified before being passed to nfs_readdir_free_large_page(). But that's okay, because nfs_readdir_free_large_page() only seems to exist as a way of calling nfs_readdir_free_pagearray() without this parameter. Let's simplify by removing pages_ptr and nfs_readdir_free_pagearray(). Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com> Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
