smb: smb2pdu.h: Avoid -Wflex-array-member-not-at-end warnings

-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]:

fs/smb/client/../common/smb2pdu.h:1225:31: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]

Add tracing for the refcounting/lifecycle of the cifs_tcon struct, marking
different events with different labels and giving each tcon its own debug
ID so that the tracelines corresponding to individual tcons can be

ksmbd: add support for durable handles v1/v2

[ Upstream commit c8efcc786146a951091588e5fa7e3c754850cb3c ]

Durable file handles allow reopening a file preserved on a short
network outage and transparent client reconnection within a timeout.
i.e. Durable handles aren't necessarily cleaned up when the opening
process terminates.

This patch add support for durable handle version 1 and 2.

To prove durable handles work on ksmbd, I have tested this patch with
the following smbtorture tests:

smb2.durable-open.open-oplock
smb2.durable-open.open-lease
smb2.durable-open.reopen1
smb2.durable-open.reopen1a

ksmbd: mark SMB2_SESSION_EXPIRED to session when destroying previous session

[ Upstream commit fa9415d4024fd0c58d24a4ad4f1826fb8bfcc4aa ]

Currently ksmbd exit connection as well destroying previous session.
When testing durable handle feaure, I found that
destroy_previous_session() should destroy only session, i.e. the
connection should be still alive. This patch mark SMB2_SESSION_EXPIRED
on the previous session to be destroyed later and not used anymore.

smb: common: simplify compression headers

[ Upstream commit 24337b60e88219816f84d633369299660e8e8cce ]

Unify compression headers (chained and unchained) into a single struct
so we can use it for the initial compression transform header
interchangeably.

Also make the OriginalPayloadSize field to be always visible in the
compression payload header, and have callers subtract its size when not
needed.

Rename the related structs to match the naming convetion used in the
other SMB2 structs.

smb3: add dynamic trace point for ioctls

[ Upstream commit 073dd87c8e1ee55ca163956f0c71249dc28aac51 ]

It can be helpful in debugging to know which ioctls are called to better
correlate them with smb3 fsctls (and opens). Add a dynamic trace point
to trace ioctls into cifs.ko

Here is sample output:
