[ Upstream commit bee90911e0138c76ee67458ac0d58b38a3190f65 ]
The wrong goto label was used for the error case and missed cleanup of the
pkt allocation.

commit 9292f8f9a2ac42eb320bced7153aa2e63d8cc13a upstream.
The code tests the dma address which legitimately can be 0.
The code should test the kernel logical address to avoid leaking eager
buffer allocations that happen to map to a dma address of 0.

[ Upstream commit f4e56ec4452f48b8292dcf0e1c4bdac83506fb8b ]

commit 4f960393a0ee9a39469ceb7c8077ae8db665cc12 upstream.
This patch fixes a crash caused by querying the QP via netlink, and
corrects the state of GSI qp. GSI qp's have a NULL qed_qp.

commit d39bf40e55e666b5905fdbd46a0dced030ce87be upstream.
Overflowing either addrlimit or bytes_togo can allow userspace to trigger

commit 829ca44ecf60e9b6f83d0161a6ef10c1304c5060 upstream.
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.
So, replace the following form:
sizeof(*pkt) + sizeof(pkt->addr[0])*n
with:
struct_size(pkt, addr, n)
Also, notice that variable size is unnecessary, hence it is removed.
This code was detected with the help of Coccinelle.

[ Upstream commit cbe71c61992c38f72c2b625b2ef25916b9f0d060 ]
kmalloc_array() is called to allocate memory for tx->descp. If it fails,
the function __sdma_txclean() is called:
__sdma_txclean(dd, tx);
However, in the function __sdma_txclean(), tx-descp is dereferenced if
tx->num_desc is not zero:
sdma_unmap_desc(dd, &tx->descp[0]);
To fix this possible null-pointer dereference, assign the return value of
kmalloc_array() to a local variable descp, and then assign it to tx->descp
if it is not NULL. Otherwise, go to enomem.

commit 43731753c4b7d832775cf6b2301dd0447a5a1851 upstream.
The current code sets an affinity hint with a cpumask_t stored on the
stack. This value can then be accessed through /proc/irq/*/affinity_hint/,
causing a segfault or returning corrupt data.
Move the cpumask_t into struct i40iw_msix_vector so it is available later.

Nothing seems to ever check for MTHCA_OPCODE_INVALID again, no idea if
this is meaningful, but it seems harmless as it deals with an invalid

commit 2ed381439e89fa6d1a0839ef45ccd45d99d8e915 upstream.
i40iw_mmap manipulates the vma->vm_pgoff to differentiate a push page mmap
vs a doorbell mmap, and uses it to compute the pfn in remap_pfn_range
without any validation. This is vulnerable to an mmap exploit as described
in: https://lore.kernel.org/r/20201119093523.7588-1-zhudi21@huawei.com
The push feature is disabled in the driver currently and therefore no push
mmaps are issued from user-space. The feature does not work as expected in
the x722 product.
Remove the push module parameter and all VMA attribute manipulations for
this feature in i40iw_mmap. Update i40iw_mmap to only allow DB user
mmapings at offset = 0. Check vm_pgoff for zero and if the mmaps are bound
to a single page.

We return 'err' in the error branch, but this variable may be set as zero

[ Upstream commit 7fd1507df7cee9c533f38152fcd1dd769fcac6ce ]
The mlx4 driver will proxy MAD packets through the PF driver. A VM or an
instantiated VF will send its MAD packets to the PF driver using
loop-back. The PF driver will be informed by an interrupt, but defer the
handling and polling of CQEs to a worker thread running on an ordered
work-queue.
Consider the following scenario: the VMs will in short proximity in time,
for example due to a network event, send many MAD packets to the PF
driver. Lets say there are K VMs, each sending N packets.
The interrupt from the first VM will start the worker thread, which will
poll N CQEs. A common case here is where the PF driver will multiplex the
packets received from the VMs out on the wire QP.
But before the wire QP has returned a send CQE and associated interrupt,
the other K - 1 VMs have sent their N packets as well.
The PF driver has to multiplex K * N packets out on the wire QP. But the
send-queue on the wire QP has a finite capacity.
So, in this scenario, if K * N is larger than the send-queue capacity of
the wire QP, we will get MAD packets dropped on the floor with this
dynamic debug message:
mlx4_ib_multiplex_mad: failed sending GSI to wire on behalf of slave 2 (-11)
and this despite the fact that the wire send-queue could have capacity,
but the PF driver isn't aware, because the wire send CQEs have not yet
been polled.
We can also have a similar scenario inbound, with a wire recv-queue larger
than the tunnel QP's send-queue. If many remote peers send MAD packets to
the very same VM, the tunnel send-queue destined to the VM could allegedly
be construed to be full by the PF driver.
This starvation is fixed by introducing separate work queues for the wire
QPs vs. the tunnel QPs.
With this fix, using a dual ported HCA, 8 VFs instantiated, we could run
cmtime on each of the 18 interfaces towards a similar configured peer,
each cmtime instance with 800 QPs (all in all 14400 QPs) without a single
CM packet getting lost.

GRH fields such as sgid_index, hop limit, et. are set in the QP context
when QP is created/modified.
Currently, when query QP is performed, we fill the GRH fields only if the

the check so we will set all relevant data for the RoCE too.
Since this data is returned to userspace, the below is an ABI regression.

commit 817a68a6584aa08e323c64283fec5ded7be84759 upstream.
The packet handling function, specifically the iteration of the qp list
for mad packet processing misses locking RCU before running through the
list. Not only is this incorrect, but the list_for_each_entry_rcu() call
can not be called with a conditional check for lock dependency. Remedy
this by invoking the rcu lock and unlock around the critical section.
This brings MAD packet processing in line with what is done for non-MAD
packets.

The panic is the result of slab entries being freed during the destruction
of the pq slab.
The code attempts to quiesce the pq, but looking for n_req == 0 doesn't
account for new requests.
Fix the issue by using SRCU to get a pq pointer and adjust the pq free
logic to NULL the fd pq pointer prior to the quiesce.

commit b5671afe5e39ed71e94eae788bacdcceec69db09 upstream.
Commit b0ffeb537f3a ("IB/mlx5: Fix iteration overrun in GSI qps") changed
the way outstanding WRs are tracked for the GSI QP. But the fix did not
cover the case when a call to ib_post_send() fails and updates index to
track outstanding.
Since the prior commmit outstanding_pi should not be bounded otherwise the
loop generate_completions() will fail.

probability to print the following smmu event:

This is because the hw will periodically refresh the qpc cache until the
next reset.
This patch fixed it by removing the action that release qpc memory in the
'hns_roce_qp_free' function.

[ Upstream commit 8f4426aa19fcdb9326ac44154a117b1a3a5ae126 ]
The QP transition optional parameters for the various transition for XRC
QPs are identical to those for RC QPs.
Many of the XRC QP transition optional parameter bits are missing from the
QP optional mask table. These omissions caused failures when doing XRC QP
state transitions.
For example, when trying to change the response timer of an XRC receive QP
via the RTS2RTS transition, the new timer value was ignored because
MLX5_QP_OPTPAR_RNR_TIMEOUT bit was missing from the optional params mask
for XRC qps for the RTS2RTS transition.
Fix this by adding the missing XRC optional parameters for all QP
transitions to the opt_mask table.
