Commit 44c58487d51a ("IB/core: Define 'ib' and 'roce' rdma_ah_attr types")
introduced the concept of type in ah_attr:
* During ib_register_device, each port is checked for its type which
is stored in ib_device's port_immutable array.
* During uverbs' modify_qp, the type is inferred using the port number
in ib_uverbs_qp_dest struct (address vector) by accessing the
relevant port_immutable array and the type is passed on to
providers.
IB spec (version 1.3) enforces a valid port value only in Reset to
Init. During Init to RTR, the address vector must be valid but port
number is not mentioned as a field in the address vector, so its
value is not validated, which leads to accesses to a non-allocated
memory when inferring the port type.
Save the real port number in ib_qp during modify to Init (when the
comp_mask indicates that the port number is valid) and use this value
to infer the port type.
Avoid copying the address vector fields if the matching bit is not set
in the attr_mask. Address vector can't be modified before the port, so
no valid flow is affected.

RDMA netlink has a complicated infrastructure for dynamically
registering and de-registering netlink clients to the NETLINK_RDMA
group. The complicated portion of this code is not widely used because
2 of the 3 current clients are statically compiled together with
netlink.c. The infrastructure, therefore, is deemed overkill.
Refactor the code to eliminate the dynamically added clients. Now all
clients are pre-registered in a client array at compile time, and at run
time they merely check-in with the infrastructure to pass their callback
table for inclusion in the pre-sized client array.
This also allows for future cleanups and removal of unneeded code in the
iwcm* netlink handler.

Pull rdma update from Doug Ledford:
"This includes two bugs against the newly added opa vnic that were
found by turning on the debug kernel options:
- sleeping while holding a lock, so a one line fix where they
switched it from GFP_KERNEL allocation to a GFP_ATOMIC allocation
- a case where they had an isolated caller of their code that could
call them in an atomic context so they had to switch their use of a
mutex to a spinlock to be safe, so this was considerably more lines
of diff because all uses of that lock had to be switched
In addition, the bug that was discussed with you already about an out
of bounds array access in ib_uverbs_modify_qp and ib_uverbs_create_ah
and is only seven lines of diff.
And finally, one fix to an earlier fix in the -rc cycle that broke
hfi1 and qib in regards to IPoIB (this one is, unfortunately, larger
than I would like for a -rc7 submission, but fixing the problem
required that we not treat all devices as though they had allocated a
netdev universally because it isn't true, and it took 70 lines of diff
to resolve the issue, but the final patch has been vetted by Intel and
Mellanox and they've both given their approval to the fix).
Summary:

- Fix for user supplied input causing kernel problems

Pull security layer updates from James Morris:
- a major update for AppArmor. From JJ:
* several bug fixes and cleanups
* the patch to add symlink support to securityfs that was floated
on the list earlier and the apparmorfs changes that make use of
securityfs symlinks
* it introduces the domain labeling base code that Ubuntu has been
carrying for several years, with several cleanups applied. And it
converts the current mediation over to using the domain labeling
base, which brings domain stacking support with it. This finally
will bring the base upstream code in line with Ubuntu and provide
a base to upstream the new feature work that Ubuntu carries.
* This does _not_ contain any of the newer apparmor mediation
features/controls (mount, signals, network, keys, ...) that
Ubuntu is currently carrying, all of which will be RFC'd on top
of this.
- Notable also is the Infiniband work in SELinux, and the new file:map
permission. From Paul:
"While we're down to 21 patches for v4.13 (it was 31 for v4.12),
the diffstat jumps up tremendously with over 2k of line changes.
Almost all of these changes are the SELinux/IB work done by
Daniel Jurgens; some other noteworthy changes include a NFS v4.2
labeling fix, a new file:map permission, and reporting of policy
capabilities on policy load"
There's also now genfscon labeling support for tracefs, which was
lost in v4.1 with the separation from debugfs.
- Smack incorporates a safer socket check in file_receive, and adds a
cap_capable call in privilege check.
- TPM as usual has a bunch of fixes and enhancements.
- Multiple calls to security_add_hooks() can now be made for the same
LSM, to allow LSMs to have hook declarations across multiple files.
- IMA now supports different "ima_appraise=" modes (eg. log, fix) from
