commit bb6d73d9add68ad270888db327514384dfa44958 upstream.
Currently irdma allows zero-length STAGs to be programmed in HW during
the kernel mode fast register flow. Zero-length MR or STAG registration
disable HW memory length checks.
Improve gaps in bounds checking in irdma by preventing zero-length STAG or
MR registrations except if the IB_PD_UNSAFE_GLOBAL_RKEY is set.
This addresses the disclosure CVE-2023-25775.

[ Upstream commit c64e9710f9241e38a1c761ed1c1a30854784da66 ]
ucmd in hns_roce_create_qp_common() are not initialized. But it works fine
until new member sdb_addr is added to struct hns_roce_ib_create_qp.
If the user-mode driver uses an old version ABI, then the value of the new
member will be undefined after ib_copy_from_udata().
This patch fixes it by initialize this variable to 0. And the default value
of the new member sdb_addr will be 0 which is invalid.

Previously when we had a RAW QP, we bound a counter to it when it moved
to INIT state, using the counter context inside RQC.
But when we try to modify that counter later in RTS state we used
modify QP which tries to change the counter inside QPC instead of RQC.
Now we correctly modify the counter set_id inside of RQC instead of QPC
for the RAW QP.

[ Upstream commit e193b7955dfad68035b983a0011f4ef3590c85eb ]
After scmd_eh_abort_handler() has called the SCSI LLD eh_abort_handler
callback, it performs one of the following actions:
* Call scsi_queue_insert().
* Call scsi_finish_command().
* Call scsi_eh_scmd_add().
Hence, SCSI abort handlers must not call scsi_done(). Otherwise all
the above actions would trigger a use-after-free. Hence remove the
scsi_done() call from srp_abort(). Keep the srp_free_req() call
before returning SUCCESS because we may not see the command again if
SUCCESS is returned.

[ Upstream commit ad215aaea4f9d637f441566cdbbc610e9849e1fa ]
Define .init_cmd_priv and .exit_cmd_priv callback functions in struct
scsi_host_template. Set .cmd_size such that the SCSI core allocates
per-command private data. Use scsi_cmd_priv() to access that private
data. Remove the req_ring pointer from struct srp_rdma_ch since it is no
longer necessary. Convert srp_alloc_req_data() and srp_free_req_data()
into functions that initialize one instance of the SRP-private command
data. This is a micro-optimization since this patch removes several
pointer dereferences from the hot path.
Note: due to commit e73a5e8e8003 ("scsi: core: Only return started
requests from scsi_host_find_tag()"), it is no longer necessary to protect
the completion path against duplicate responses.
