commit ae4ccca47195332c69176b8615c5ee17efd30c46 upstream.
There are common cases where copy_file_range can noisily
log "source and target of copy not on same server"
e.g. the mv command across mounts to two different server's shares.
Change this to informational rather than logging as an error.
A followon patch will add dynamic trace points e.g. for
cifs_file_copychunk_range

commit d2346e2836318a227057ed41061114cbebee5d2a upstream.
If you try to set /proc/fs/cifs/SecurityFlags to 1 it
will set them to CIFSSEC_MUST_NTLMV2 which no longer is
relevant (the less secure ones like lanman have been removed
from cifs.ko) and is also missing some flags (like for
signing and encryption) and can even cause mount to fail,
so change this to set it to Kerberos in this case.
Also change the description of the SecurityFlags to remove mention
of flags which are no longer supported.

-Wflex-array-member-not-at-end is coming in GCC-14, and we are getting
ready to enable it globally.
So, in order to avoid ending up with a flexible-array member in the
middle of multiple other structs, we use the `__struct_group()` helper
to separate the flexible array from the rest of the members in the
flexible structure, and use the tagged `struct create_context_hdr`
instead of `struct create_context`.
So, with these changes, fix 51 of the following warnings[1]:

[ Upstream commit 71f15c90e785d1de4bcd65a279e7256684c25c0d ]
There is a shortcoming in the current implementation of the file
lease mechanism exposed when the lease keys were attempted to be
reused for unlink, rename and set_path_size operations for a client. As
per MS-SMB2, lease keys are associated with the file name. Linux smb
client maintains lease keys with the inode. If the file has any hardlinks,
it is possible that the lease for a file be wrongly reused for an
operation on the hardlink or vice versa. In these cases, the mentioned
compound operations fail with STATUS_INVALID_PARAMETER.
This patch adds a fallback to the old mechanism of not sending any
lease with these compound operations if the request with lease key fails
with STATUS_INVALID_PARAMETER.
Resending the same request without lease key should not hurt any
functionality, but might impact performance especially in cases where
the error is not because of the usage of wrong lease key and we might
end up doing an extra roundtrip.

[ Upstream commit ffceb7640cbfe6ea60e7769e107451d63a2fe3d3 ]
When a file/dentry has been deleted before closing all its open
handles, currently, closing them can add them to the deferred
close list. This can lead to problems in creating file with the
same name when the file is re-created before the deferred close
completes. This issue was seen while reusing a client's already
existing lease on a file for compound operations and xfstest 591
failed because of the deferred close handle that remained valid
even after the file was deleted and was being reused to create a
file with the same name. The server in this case returns an error
on open with STATUS_DELETE_PENDING. Recreating the file would
fail till the deferred handles are closed (duration specified in
closetimeo).
This patch fixes the issue by flagging all open handles for the
deleted file (file path to be precise) by setting
status_file_deleted to true in the cifsFileInfo structure. As per
the information classes specified in MS-FSCC, SMB2 query info
response from the server has a DeletePending field, set to true
to indicate that deletion has been requested on that file. If
this is the case, flag the open handles for this file too.
When doing close in cifs_close for each of these handles, check the
value of this boolean field and do not defer close these handles
if the corresponding filepath has been deleted.

[ Upstream commit 2c7d399e551ccfd87bcae4ef5573097f3313d779 ]
Currently, when a rename, unlink or set path size compound operation
is requested on a file that has a lot of dirty pages to be written
to the server, we do not send the lease key for these requests. As a
result, the server can assume that this request is from a new client, and
send a lease break notification to the same client, on the same
connection. As a response to the lease break, the client can consume
several credits to write the dirty pages to the server. Depending on the
server's credit grant implementation, the server can stop granting more
credits to this connection, and this can cause a deadlock (which can only
be resolved when the lease timer on the server expires).
One of the problems here is that the client is sending no lease key,
even if it has a lease for the file. This patch fixes the problem by
reusing the existing lease key on the file for rename, unlink and set path
size compound operations so that the client does not break its own lease.
A very trivial example could be a set of commands by a client that
maintains open handle (for write) to a file and then tries to copy the
contents of that file to another one, eg.,
tail -f /dev/null > myfile &
mv myfile myfile2
Presently, the network capture on the client shows that the move (or
rename) would trigger a lease break on the same client, for the same file.
With the lease key reused, the lease break request-response overhead is
eliminated, thereby reducing the roundtrips performed for this set of
operations.
The patch fixes the bug described above and also provides perf benefit.

File open requests made to the server contain a
CreateGuid, which is used by the server to identify
the open request. If the same request needs to be
replayed, it needs to be sent with the same CreateGuid
in the durable handle v2 context.
Without doing so, we could end up leaking handles on
the server when:
1. multichannel is used AND
2. connection goes down, but not for all channels
This is because the replayed open request would have a
new CreateGuid and the server will treat this as a new
request and open a new handle.
This change fixes this by reusing the existing create_guid
stored in the cached fid struct.

MS-SMB2 states that the header flag SMB2_FLAGS_REPLAY_OPERATION
needs to be set when a command needs to be retried, so that
the server is aware that this is a replay for an operation that
appeared before.
This can be very important, for example, for state changing
operations and opens which get retried following a reconnect;
since the client maybe unaware of the status of the previous
open.
This is particularly important for multichannel scenario, since
disconnection of one connection does not mean that the session
is lost. The requests can be replayed on another channel.
This change also makes use of exponential back-off before replays
and also limits the number of retries to "retrans" mount option
value.
Also, this change does not modify the read/write codepath.

[ Upstream commit 516eea97f92f1e7271f20835cfe9e73774b0f8cc ]
Recently, cifs_chan_update_iface was modified to not
remove an iface if a suitable replacement was not found.
With that, there were two conditionals that were exactly
the same. This change removes that extra condition check.
Also, fixed a logging in the same function to indicate
the correct message.
