Fix a regression that was introduced by commit 0c2e53f1 (NFS: Remove the unused "lookupfh()" version of nfs4_proc_lookup()). In the case where the lookup gets an NFS4ERR_MOVED, we want to return the result of nfs4_get_referral(). Instead, that value is getting clobbered by the call to nfs4_handle_exception()...

commit d953126a changed how nfs_atomic_lookup handles an -EISDIR return from an OPEN call. Prior to that patch, that caused the client to fall back to doing a normal lookup. When that patch went in, the code began returning that error to userspace. The d_revalidate codepath however never had the corresponding change, so it was still possible to end up with a NULL ctx->state pointer after that. That patch caused a regression. When we attempt to open a directory that does not have a cached dentry, that open now errors out with EISDIR. If you attempt the same open with a cached dentry, it will succeed. Fix this by reverting the change in nfs_atomic_lookup and allowing attempts to open directories to fall back to a normal lookup Also, add a NFSv4-specific f_ops->open routine that just returns -ENOTDIR. This should never be called if things are working properly, but if it ever is, then the dprintk may help in debugging. To facilitate this, a new file_operations field is also added to the nfs_rpc_ops struct. Cc: stable@kernel.org Signed-off-by:

It would then unconditionally try return a flush completion via qib_send_complete() for an invalid wqe, or worse a valid one that is not queued. The panic results when the completion code tries to maintain an MR reference count for a NULL MR. This fix modifies logic to only send one completion per qib_make_rc_req() call and changing the completion status from IB_WC_SUCCESS to IB_WC_WR_FLUSH_ERR as the completions progress. The outer loop will call as many times as necessary to flush the queue. Reviewed-by:

The driver counted on the transactional nature of iSCSI login/text flows and used the same buffer for both the request and the response. We also went further and did DMA mapping only once, with DMA_FROM_DEVICE, which violates the DMA mapping API. Fix that by using different buffers, one for requests and one for responses, and use the correct DMA mapping direction for each. Signed-off-by:
