[PATCH v3 0/4] smb: smbdirect/client/server: relax WARN_ON_ONCE(SMBDIRECT_SOCKET_*) checks

[Stefan Metzmacher <metze@samba.org>]

Hi,

here are some small cleanups for a problem Nanjae reported,
where two WARN_ON_ONCE(sc->status != ...) checks where triggered
by a Windows 11 client.

The patches should relax the checks if an error happened before,
they are intended for 6.18 final, as far as I can see the
problem was introduced during the 6.18 cycle only.

Given that v1 of this patchset produced a very useful WARN_ONCE()
message, I'd really propose to keep this for 6.18, also for the
client where the actual problem may not exists, but if they
exist, it will be useful to have the more useful messages
in 6.16 final.

Thanks!

v3: move __SMBDIRECT_SOCKET_DISCONNECT() defines before including
    smbdirect headers in order to avoid problems with the follow
    up changes for 6.19

v2: adjust for the case where the recv completion arrives before
    RDMA_CM_EVENT_ESTABLISHED and improve commit messages

Stefan Metzmacher (4):
  smb: smbdirect: introduce SMBDIRECT_DEBUG_ERR_PTR() helper
  smb: smbdirect: introduce SMBDIRECT_CHECK_STATUS_{WARN,DISCONNECT}()
  smb: server: relax WARN_ON_ONCE(SMBDIRECT_SOCKET_*) checks in
    recv_done() and smb_direct_cm_handler()
  smb: client: relax WARN_ON_ONCE(SMBDIRECT_SOCKET_*) checks in
    recv_done() and smbd_conn_upcall()
