Leon Romanovsky 25ed049891 RDMA/efa: Remove double QP type assignment
[ Upstream commit f9193d266347fe9bed5c173e7a1bf96268142a79 ]

The QP type is set by the IB/core and shouldn't be set in the driver.

Mike Marciniszyn 7930b1f98d IB/hfi1: Adjust pkey entry in index 0
[ Upstream commit 62004871e1fa7f9a60797595c03477af5b5ec36f ]

It is possible for the primary IPoIB network device associated with any
RDMA device to fail to join certain multicast groups preventing IPv6
neighbor discovery and possibly other network ULPs from working
correctly. The IPv4 broadcast group is not affected as the IPoIB network
device handles joining that multicast group directly.

This is because the primary IPoIB network device uses the pkey at ndex 0
in the associated RDMA device's pkey table. Anytime the pkey value of
index 0 changes, the primary IPoIB network device automatically modifies
it's broadcast address (i.e. /sys/class/net/[ib0]/broadcast), since the
broadcast address includes the pkey value, and then bounces carrier. This
includes initial pkey assignment, such as when the pkey at index 0
transitions from the opa default of invalid (0x0000) to some value such as
the OPA default pkey for Virtual Fabric 0: 0x8001 or when the fabric
manager is restarted with a configuration change causing the pkey at index
0 to change. Many network ULPs are not sensitive to the carrier bounce and
are not expecting the broadcast address to change including the linux IPv6
stack.  This problem does not affect IPoIB child network devices as their
pkey value is constant for all time.

To mitigate this issue, change the default pkey in at index 0 to 0x8001 to
cover the predominant case and avoid issues as ipoib comes up and the FM
sweeps.

At some point, ipoib multicast support should automatically fix
non-broadcast addresses as it does with the primary broadcast address.

Tuo Li 8a21e84334 IB/hfi1: Fix possible null-pointer dereference in _extend_sdma_tx_descs()
[ 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.

Alaa Hleihel e3ecd9c09f IB/mlx5: Fix initializing CQ fragments buffer
commit 2ba0aa2feebda680ecfc3c552e867cf4d1b05a3a upstream.

The function init_cq_frag_buf() can be called to initialize the current CQ
fragments buffer cq->buf, or the temporary cq->resize_buf that is filled
during CQ resize operation.

However, the offending commit started to use function get_cqe() for
getting the CQEs, the issue with this change is that get_cqe() always
returns CQEs from cq->buf, which leads us to initialize the wrong buffer,
and in case of enlarging the CQ we try to access elements beyond the size
of the current cq->buf and eventually hit a kernel panic.

commit 404e5a12691fe797486475fe28cc0b80cb8bef2c upstream.

Currently when mlx4 maps the hca_core_clock page to the user space there
are read-modifiable registers, one of which is semaphore, on this page as
well as the clock counter. If user reads the wrong offset, it can modify
the semaphore and hang the device.

Do not map the hca_core_clock page to the user space unless the device has
been put in a backwards compatibility mode to support this feature.

After this patch, mlx4 core_clock won't be mapped to user space on the
majority of existing devices and the uverbs device time feature in
ibv_query_rt_values_ex() will be disabled.

bnxt_qplib_alloc_res calls
bnxt_qplib_free_res()->bnxt_qplib_free_dpi_tbl() in the fail branch. Then
dpit->dbr_bar_reg_iomem is freed in the second time by pci_iounmap().

My patch set dpit->dbr_bar_reg_iomem to NULL after it is freed by

Potnuri Bharat Teja d7ba506b00 RDMA/cxgb4: add missing qpid increment
[ Upstream commit 3a6684385928d00b29acac7658a5ae1f2a44494c ]

missing qpid increment leads to skipping few qpids while allocating QP.
This eventually leads to adapter running out of qpids after establishing
fewer connections than it actually supports.
Current patch increments the qpid correctly.

[ Upstream commit fbb7dc5db6dee553b5a07c27e86364a5223e244c ]

gcc points out a suspicious mixing of enum types in a function that
converts from MTHCA_OPCODE_* values to IB_WC_* values:

drivers/infiniband/hw/mthca/mthca_cq.c: In function 'mthca_poll_one':
drivers/infiniband/hw/mthca/mthca_cq.c:607:21: warning: implicit conversion from 'enum <anonymous>' to 'enum ib_wc_opcode' [-Wenum-conversion]
  607 |    entry->opcode    = MTHCA_OPCODE_INVALID;

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
input.

Remove MTHCA_OPCODE_INVALID and set the ib_wc_opcode to 0xFF, which is
still bogus, but at least doesn't make compiler warnings.

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.

Wenpeng Liang eff57fbc23 RDMA/hns: Fix the wrong value of rnr_retry when querying qp
[ Upstream commit 99fcf82521d91468ee6115a3c253aa032dc63cbc ]

The rnr_retry returned to the user is not correct, it should be got from
another fields in QPC.

Sindhu, Devale b79dd19168 i40iw: Add support to make destroy QP synchronous
[ Upstream commit f2334964e969762e266a616acf9377f6046470a2 ]

Occasionally ib_write_bw crash is seen due to access of a pd object in
i40iw_sc_qp_destroy after it is freed. Destroy qp is not synchronous in
i40iw and thus the iwqp object could be referencing a pd object that is
freed by ib core as a result of successful return from i40iw_destroy_qp.

Wait in i40iw_destroy_qp till all QP references are released and destroy
the QP and its associated resources before returning.  Switch to use the
refcount API vs atomic API for lifetime management of the qp.

[ Upstream commit 0ec52f0194638e2d284ad55eba5a7aff753de1b9 ]

set_reg_wr() always fails if !umr_modify_entity_size_disabled because
mlx5_ib_can_use_umr() always fails. Without set_reg_wr() IB_WR_REG_MR
doesn't work and that means the device should not advertise
IB_DEVICE_MEM_MGT_EXTENSIONS.

commit 59e8970b37 ("RDMA/qedr: Return max inline data in QP query

the max inline size based on protocol.  This size is cached in the device
attributes
