Pull GFS2 updates from Andreas Gruenbacher: "We've got the following patches ready for this merge window: - "gfs2: Fix loop in gfs2_rbm_find (v2)" A rework of a fix we ended up reverting in 5.0 because of an iozone performance regression. - "gfs2: read journal in large chunks" "gfs2: fix race between gfs2_freeze_func and unmount" An improved version of a commit we also ended up reverting in 5.0 because of a regression in xfstest generic/311. It turns out that the journal changes were mostly innocent and that unfreeze didn't wait for the freeze to complete, which caused the filesystem to be unmounted before it was actually idle. - "gfs2: Fix occasional glock use-after-free" "gfs2: Fix iomap write page reclaim deadlock" "gfs2: Fix lru_count going negative" Fixes for various problems reported and partially fixed by Citrix engineers. Thank you very much. - "gfs2: clean_journal improperly set sd_log_flush_head" Another fix from Bob. - .. and a few other minor cleanups" * tag 'gfs2-for-5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2: gfs2: read journal in large chunks gfs2: Fix iomap write page reclaim deadlock gfs2: fix race between gfs2_freeze_func and unmount gfs2: Rename gfs2_trans_{add_unrevoke => remove_revoke} gfs2: Rename sd_log_le_{revoke,ordered} gfs2: Remove unnecessary extern declarations gfs2: Remove misleading comments in gfs2_evict_inode gfs2: Replace gl_revokes with a GLF flag gfs2: Fix occasional glock use-after-free gfs2: clean_journal improperly set sd_log_flush_head gfs2: Fix lru_count going negative gfs2: Fix loop in gfs2_rbm_find (v2)

Two of the common symlink formats use reparse points (unlike mfsymlinks and also unlike the SMB1 posix extensions). This is the first part of the fixes to allow these reparse points (NFS style and Windows symlinks) to be resolved properly as symlinks by the client.

The flags were named confusingly. CIFS_ASYNC_OP now just means that we will not block waiting for credits to become available so we thus rename this to be CIFS_NON_BLOCKING. Change CIFS_NO_RESP to CIFS_NO_RSP_BUF to clarify that we will actually get a response from the server but we will not get/do not want a response buffer. Delete CIFSSMBNotify.

For SMB1 oplock breaks we would grab one credit while sending the PDU but we would never relese the credit back since we will never receive a response to this from the server. Eventuallt this would lead to a hang once all credits are leaked. Fix this by defining a new flag CIFS_NO_SRV_RSP which indicates that there is no server response to this command and thus we need to add any credits back immediately after sending the PDU.

Add the SMB3 protocol flag definitions and structs for change notify. Future patches will add the hooks to allow it to be invoked from the client. See MS-FSCC 2.6 and MS-SMB2 2.2.35 Signed-off-by: Steve French <stfrench@microsoft.com> Reviewed-by: Ronnie Sahlberg <lsahlber@redhat.com>

For zero-range that also extend the file we were sending this as a compound of two different operations; a fsctl to set-zero-data for the range and then an additional set-info to extend the file size. This does not work for Azure since it does not support this fsctl which leads to fallocate(FALLOC_FL_ZERO_RANGE) failing but still changing the file size. To fix this we un-compound this and send these two operations as separate commands, firsat one command to set-zero-data for the range and it this was successful we proceed to send a set-info to update the file size. This fixes xfstest generic/469 for Azure servers. Signed-off-by: Ronnie Sahlberg <lsahlber@redhat.com> Signed-off-by: Steve French <stfrench@microsoft.com>

Remove the conditional to fail zero-range if the file is not flagged as sparse. You can still zero out a range in SMB2 even for non-sparse files. Tested with stock windows16 server.

SMB2 Ioctl responses from servers may respond with both the request blob from the client followed by the actual reply blob for ioctls that are bi-directional. In that case we can not assume that the reply blob comes immediately after the ioctl response structure.

Originally, filemap_write_and_wait took the i_mutex internally, but commit 02c24a82 pushed the mutex acquisition into the individual fsync routines, leaving it up to the subsystem maintainers to remove it if it wasn't needed. For cifs, I see no reason to take the inode_lock here. All of the operations inside that lock are protected in other ways.

When transport is being destroyed, it's possible that some processes may hold memory registrations that need to be deregistred. Call them first so nobody is using transport resources, and it can be destroyed. Signed-off-by: Long Li <longli@microsoft.com> Signed-off-by: Steve French <stfrench@microsoft.com>

Memory registration failure doesn't mean this I/O has failed, it means the transport is hitting I/O error or needs reconnect. This error is not from the server.

Failure to send a packet doesn't mean it's a permanent failure, it can't be returned to user process. This I/O should be retried or failed based on server packet response and transport health.

On transport recoonect, upper layer CIFS code destroys the current transport and then recoonect. This code path is not used by SMBD, in that SMBD destroys its transport on RDMA disconnect notification independent of CIFS upper layer behavior. This approach adds some costs to SMBD layer to handle transport shutdown and restart, and to deal with several racing conditions on reconnecting transport. Re-work this code path by introducing a new smbd_destroy. This function is called form upper layer to ask SMBD to destroy the transport. SMBD will no longer need to destroy the transport by itself while worrying about data transfer is in progress. The upper layer guarantees the transport is locked. change log: v2: fix build errors when CONFIG_CIFS_SMB_DIRECT is not configured Signed-off-by: Long Li <longli@microsoft.com> Signed-off-by: Steve French <stfrench@microsoft.com>
