Kalderon, Michal e3fd112cbf RDMA/qedr: Fix kernel panic when running fio over NFSoRDMA
Race in qedr_poll_cq, lastest_cqe wasn't protected by lock,
leading to a case where two context's accessing poll_cq at
the same time lead to one of them having a pointer to an old
latest_cqe and reading an invalid cqe element

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma

Pull rdma updates from Doug Ledford:
 "This is a fairly plain pull request. Lots of driver updates across the
  stack, a huge number of static analysis cleanups including a close to
  50 patch series from Bart Van Assche, and a number of new features
  inside the stack such as general CQ moderation support.

  Nothing really stands out, but there might be a few conflicts as you
  take things in. In particular, the cleanups touched some of the same
  lines as the new timer_setup changes.

  Everything in this pull request has been through 0day and at least two
  days of linux-next (since Stephen doesn't necessarily flag new
  errors/warnings until day2). A few more items (about 30 patches) from
  Intel and Mellanox showed up on the list on Tuesday. I've excluded
  those from this pull request, and I'm sure some of them qualify as
  fixes suitable to send any time, but I still have to review them
  fully. If they contain mostly fixes and little or no new development,
  then I will probably send them through by the end of the week just to
  get them out of the way.

  There was a break in my acceptance of patches which coincides with the
  computer problems I had, and then when I got things mostly back under
  control I had a backlog of patches to process, which I did mostly last
  Friday and Monday. So there is a larger number of patches processed in
  that timeframe than I was striving for.

  Summary:
   - Add iWARP support to qedr driver
   - Lots of misc fixes across subsystem
   - Multiple update series to hns roce driver
   - Multiple update series to hfi1 driver
   - Updates to vnic driver

Mask out non vlan id fields from vlan tag of the QED LL2 RX GSI

Arnd Bergmann bd491d2ad3 RDMA/qedr: fix build error without ipv6
When CONFIG_IPV6 disabled, we run into a link error:

drivers/infiniband/hw/qedr/qedr_iw_cm.o: In function `qedr_addr6_resolve.isra.3':
qedr_iw_cm.c:(.text+0x4e0): undefined reference to `ip6_route_output_flags'

The ipv6 handling code is obviously not needed here, so this
adds a compile-time check for the Kconfig symbol in all three
places in the code that decide between ipv4 and ipv6.

We don't have to worry about a link error wtih QEDR=y/IPV6=m, as
that configuration is already prohibited by CONFIG_INFINIBAND
depending on "m || IPV6 != m".

There is a need to forward FW version to user space
application through RDMA netlink. In order to make it safe, there
is need to declare nla_policy and limit the size of FW string.

The new define IB_FW_VERSION_NAME_MAX will limit the size of
FW version string. That define was chosen to be equal to
ETHTOOL_FWVERS_LEN, because many drivers anyway are limited
by that value indirectly.

The introduction of this define allows us to remove the string size

the information to the protocol-driver [or internal qed consumer].
Since we have several flavors of ll2 employeed by the driver,
each handler needs to do an if-else to determine the right functionality
to use based on the connection type.

In order to make things more scalable [given that we're going to add
additional types of ll2 flavors] move the infrastrucutre into using
a callback-based approach - the callbacks would be provided as part

Artemy Kovalyov 3e7e1193e2 IB: Replace ib_umem page_size by page_shift
Size of pages are held by struct ib_umem in page_size field.

It is better to store it as an exponent, because page size by nature
is always power-of-two and used as a factor, divisor or ilog2's argument.

The conversion of page_size to be page_shift allows to have portable
code and avoid following error while compiling on ARM:

  ERROR: "__aeabi_uldivmod" [drivers/infiniband/core/ib_core.ko] undefined!

Mintz, Yuval be086e7c53 qed*: Utilize Firmware 8.15.3.0
This patch advances the qed* drivers into using the newer firmware -
This solves several firmware bugs, mostly related [but not limited to]
various init/deinit issues in various offloaded protocols.

It also introduces a major 4-Cached SGE change in firmware, which can be
seen in the storage drivers' changes.

In addition, this firmware is required for supporting the new QL41xxx
series of adapters; While this patch doesn't add the actual support,
the firmware contains the necessary initialization & firmware logic to
operate such adapters [actual support would be added later on].

Linus Torvalds ac1820fb28 This is a tree wide change and has been kept separate for that reason.
Bart Van Assche noted that the ib DMA mapping code was significantly
 similar enough to the core DMA mapping code that with a few changes
 it was possible to remove the IB DMA mapping code entirely and
 switch the RDMA stack to use the core DMA mapping code.  This resulted
 in a nice set of cleanups, but touched the entire tree.  This branch
 will be submitted separately to Linus at the end of the merge window
 as per normal practice for tree wide changes like this.

In qedr_init_user_queue():
 - simplify the test for the return value, no need to test for NULL
 - propagate the error pointer if needed, otherwise 0 (success) is returned.
   This is spurious.

In init_mr_info():
 - test the return value with IS_ERR
 - propagate the error pointer if needed instead of an exlictit -ENOMEM.
   This is a no-op as the only error pointer that we can have here is

Or Gerlitz c4550c63b3 IB: Query ports via the core instead of direct into the driver
Change the drivers to call ib_query_port in their get port
immutable handler instead of their own query port handler.

Doing this required to set the core cap flags of this device
before the ib_query_port call is made, since the IB core might
need these caps to serve the port query.

Drivers are ensured by the IB core that the port attributes passed
to the port query verb implementation are zero, and hence we
removed the zeroing from the drivers.

This patch doesn't add any new functionality.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma

Pull rdma updates from Doug Ledford:
 "This is the complete update for the rdma stack for this release cycle.

  Most of it is typical driver and core updates, but there is the
  entirely new VMWare pvrdma driver. You may have noticed that there
  were changes in DaveM's pull request to the bnxt Ethernet driver to
  support a RoCE RDMA driver. The bnxt_re driver was tentatively set to
  be pulled in this release cycle, but it simply wasn't ready in time
  and was dropped (a few review comments still to address, and some
  multi-arch build issues like prefetch() not working across all
  arches).

  Summary:

   - shared mlx5 updates with net stack (will drop out on merge if
     Dave's tree has already been merged)

   - driver updates: cxgb4, hfi1, hns-roce, i40iw, mlx4, mlx5, qedr, rxe

   - debug cleanups

   - new connection rejection helpers

   - SRP updates

   - various misc fixes

   - new paravirt driver from vmware"

Moni Shoua 477864c8fc IB/core: Let create_ah return extended response to user
Add struct ib_udata to the signature of create_ah callback that is
implemented by IB device drivers. This allows HW drivers to return extra
data to the userspace library.
This patch prepares the ground for mlx5 driver to resolve destination
mac address for a given GID and return it to userspace.
This patch was previously submitted by Knut Omang as a part of the
patch set to support Oracle's Infiniband HCA (SIF).
