Add timeout to cm_destroy_id, so that userspace can trigger any data
collection that would help in analyzing the cause of delay in destroying
the cm_id.
New noinline function helps dtrace/ebpf programs to hook on to it.
Existing functionality isn't changed except triggering a probe-able new
function at every timeout interval.
We have seen cases where CM messages stuck with MAD layer (either due to
software bug or faulty HCA), leading to cm_id getting stuck in the
following call stack. This patch helps in resolving such issues faster.

Introduce mana_ib_create_dma_region() to create dma regions with iova
for MRs. It allows creating MRs with any page offset. Previously,
only page-aligned addresses worked.
For dma regions that must have a zero dma offset (e.g., for queues),
mana_ib_create_zero_offset_dma_region() is added.
To get the zero offset, ib_umem_find_best_pgoff() is used with zero
pgoff_bitmask.

SCCC (SCC Context) is a context with QP granularity that contains
information about congestion control. Dump SCCC and QPC together
to improve troubleshooting.
When dumping raw QPC with rdmatool, there will be a total of 576 bytes
data output, where the first 512 bytes is QPC and the last 64 bytes is
SCCC. When congestion control is disabled, the 64 byte SCCC will be all 0.
Example:
$rdma res show qp -jpr
[ {
"ifindex": 0,
"ifname": "hns_0",
"data": [ 67,0,0,0... 512bytes
4,0,2... 64bytes]

-Wflex-array-member-not-at-end is coming in GCC-14, and we are getting
ready to enable it globally.
There are currently a couple of objects (`alloc_head` and `bundle`) in
`struct bundle_priv` that contain a couple of flexible structures:
struct bundle_priv {
/* Must be first */
struct bundle_alloc_head alloc_head;
...
/*
* Must be last. bundle ends in a flex array which overlaps
* internal_buffer.
*/
struct uverbs_attr_bundle bundle;
u64 internal_buffer[32];
};
So, in order to avoid ending up with a couple of flexible-array members
in the middle of a struct, we use the `struct_group_tagged()` helper to
separate the flexible array from the rest of the members in the flexible
structures:
struct uverbs_attr_bundle {
struct_group_tagged(uverbs_attr_bundle_hdr, hdr,
... the rest of the members
);
struct uverbs_attr attrs[];
};
With the change described above, we now declare objects of the type of
the tagged struct without embedding flexible arrays in the middle of
another struct:
struct bundle_priv {
/* Must be first */
struct bundle_alloc_head_hdr alloc_head;
...
struct uverbs_attr_bundle_hdr bundle;
u64 internal_buffer[32];
};
We also use `container_of()` whenever we need to retrieve a pointer
to the flexible structures.
Notice that the `bundle_size` computed in `uapi_compute_bundle_size()`
remains the same.
So, with these changes, fix the following warnings:
drivers/infiniband/core/uverbs_ioctl.c:45:34: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]

granularity
Currently, congestion control algorithm is statically configured in
FW, and all QPs use the same algorithm(except UD which has a fixed
configuration of DCQCN). This is not flexible enough.
Support userspace configuring congestion control algorithm with QP
granularity while creating QPs. If the algorithm is not specified in
userspace, use the default one.

When a struct containing a flexible array is included in another struct,
and there is a member after the struct-with-flex-array, there is a
possibility of memory overlap. These cases must be audited [1]. See:
struct inner {
...
int flex[];
};
struct outer {
...
struct inner header;
int overlap;
...
};
This is the scenario for all the "struct *_filter" structures that are
included in the following "struct ib_flow_spec_*" structures:
struct ib_flow_spec_eth
struct ib_flow_spec_ib
struct ib_flow_spec_ipv4
struct ib_flow_spec_ipv6
struct ib_flow_spec_tcp_udp
struct ib_flow_spec_tunnel
struct ib_flow_spec_esp
struct ib_flow_spec_gre
struct ib_flow_spec_mpls
The pattern is like the one shown below:
struct *_filter {
...
u8 real_sz[];
};
struct ib_flow_spec_* {
...
struct *_filter val;
struct *_filter mask;
};
In this case, the trailing flexible array "real_sz" is never allocated
and is only used to calculate the size of the structures. Here the use
of the "offsetof" helper can be changed by the "sizeof" operator because
the goal is to get the size of these structures. Therefore, the trailing
flexible arrays can also be removed.
However, due to the trailing padding that can be induced in structs it
is possible that the:
offsetof(struct *_filter, real_sz) != sizeof(struct *_filter)
This situation happens with the "struct ib_flow_ipv6_filter" and to
avoid it the "__packed" macro is used in this structure. But now, the
"sizeof(struct ib_flow_ipv6_filter)" has changed. This is not a problem
since this size is not used in the code.
The situation now is that "sizeof(struct ib_flow_spec_ipv6)" has also
changed (this struct contains the struct ib_flow_ipv6_filter). This is
also not a problem since it is only used to set the size of the "union
ib_flow_spec", which can store all the "ib_flow_spec_*" structures.

Commit 27c5fd271d8b ("RDMA/hns: The UD mode can only be configured
with DCQCN") adds a check of congest control alorithm for UD. But
that patch causes a problem: hr_dev->caps.congest_type is global,
used by all QPs, so modifying this field to DCQCN for UD QPs causes
other QPs unable to use any other algorithm except DCQCN.
Revert the modification in commit 27c5fd271d8b ("RDMA/hns: The UD
mode can only be configured with DCQCN"). Add a new field cong_type

Upon rare occasions, KASAN reports a use-after-free Write
in srpt_refresh_port().
This seems to be because an event handler is registered before the

Instead, only register the event handler after srpt device initialization
is complete.

When creating EQs we take into consideration the max number of EQs the
device reported it can support and the number of available CPUs. There
are situations where the number of EQs the device reported it can
support and the PCI configuration of MSI-X is different, take it in
account as well when creating EQs.
Also request at least 1 MSI-X vector for the management queue and allow
the kernel to return a number of vectors in a range between 1 and the
max supported MSI-X vectors according to the PCI config.

'struct hns_roce_hem' is used to refer to the last level of
dma buffer managed by the hw, pointed by a single BA(base
address) in the previous level of BT(base table), so the dma
buffer in 'struct hns_roce_hem' must be contiguous.
Right now the size of dma buffer in 'struct hns_roce_hem' is
decided by mhop->buf_chunk_size in get_hem_table_config(),
which ensure the mhop->buf_chunk_size is power of two of
PAGE_SIZE, so there will be only one contiguous dma buffer
allocated in hns_roce_alloc_hem(), which means hem->chunk_list
and chunk->mem for linking multi dma buffers is unnecessary.
This patch removes the hem->chunk_list and chunk->mem and other
related macro and function accordingly.
