Let's call unmap_cont_bufs when failure happens, and also only update
mrs_num after everything is settled which means we can remove 'mri'.

The RDMA_CM_EVENT_CONNECT_REQUEST is quite different to other types,
let's check it separately at the beginning of routine, then we can
avoid the indentation accordingly.

When allocating PBLE's for a large CQ, it is possible
that a 2-level PBLE is returned which would cause the
CQ allocation to fail since 1-level is assumed and checked for.
Fix this by requesting a level one PBLE only.

The opcode written by HW, in the RQ CQE, is the
RoCEv2/iWARP protocol opcode from the received
packet and not the SW opcode as currently assumed.
Fix this by returning the raw operation type and
queue type in the CQE to irdma_process_cqe and add
2 helpers set_ib_wc_op_sq set_ib_wc_op_rq to map
IRDMA HW op types to IB op types.
Note that for iWARP, only Write with Immediate is
supported so the opcode can only be IB_WC_RECV_RDMA_WITH_IMM
when there is immediate data present.

A malicious user may write undefined values into memory mapped completion
queue elements status or opcode. Undefined status or opcode values will
result in out-of-bounds access to an array mapping siw internal
representation of opcode and status to RDMA core representation when
reaping CQ elements. While siw detects those undefined values, it did not
correctly set completion status to a defined value, thus defeating the
whole purpose of the check.
This bug leads to the following Smatch static checker warning:
drivers/infiniband/sw/siw/siw_cq.c:96 siw_reap_cqe()
error: buffer overflow 'map_cqe_status' 10 <= 21

When filling a cm_id entry, return "-EAGAIN" instead of 0 if the cm_id
doesn'the have the same port as requested, otherwise an incomplete entry
may be returned, which causes "rdam res show cm_id" to return an error.
For example on a machine with two rdma devices with "rping -C 1 -v -s"
running background, the "rdma" command fails:
$ rdma -V
rdma utility, iproute2-5.19.0
$ rdma res show cm_id
link mlx5_0/- cm-idn 0 state LISTEN ps TCP pid 28056 comm rping src-addr 0.0.0.0:7174
error: Protocol not available
While with this fix it succeeds:
$ rdma res show cm_id
link mlx5_0/- cm-idn 0 state LISTEN ps TCP pid 26395 comm rping src-addr 0.0.0.0:7174
link mlx5_1/- cm-idn 0 state LISTEN ps TCP pid 26395 comm rping src-addr 0.0.0.0:7174

The number of maximum SGl entries should be computed from the maximum
WQE size for the intended queue type and the corresponding OOB data
size. This guarantees the hardware queue can successfully queue requests
up to the queue depth exposed to the upper layer.

For outgoing packets, the PF requires the VF to configure the vport with
corresponding protection domain and doorbell ID for the kernel or user
context. The vport can't be shared between different contexts.
Implement the logic to exclusively take over the vport by either the
Ethernet device or RDMA device.

Correctly set send queue element opcode during immediate work request
flushing in post sendqueue operation, if the QP is in ERROR state.
An undefined ocode value results in out-of-bounds access to an array
for mapping the opcode between siw internal and RDMA core representation
in work completion generation. It resulted in a KASAN BUG report
of type 'global-out-of-bounds' during NFSoRDMA testing.
This patch further fixes a potential case of a malicious user which may
write undefined values for completion queue elements status or opcode,
if the CQ is memory mapped to user land. It avoids the same out-of-bounds
access to arrays for status and opcode mapping as described above.

The mlx5 driver dumps the entire CQE buffer by default for few syndromes.
Some syndromes are expected due to the application behavior [ex:
MLX5_CQE_SYNDROME_REMOTE_ACCESS_ERR, MLX5_CQE_SYNDROME_REMOTE_OP_ERR and
MLX5_CQE_SYNDROME_LOCAL_PROT_ERR]. Hence, for these syndromes, the patch
converts the log level from KERN_WARNING to KERN_DEBUG. This enables the
application to get the CQE buffer dump by changing to KERN_DEBUG level
as and when needed.
