Mellanox, mlx5 fixes 2018-01-11
The following series includes fixes to mlx5 core and netdev driver.
To highlight we have two critical fixes in this series:
1st patch from Eran to address a fix for Host2BMC Breakage.
2nd patch from Saeed to address the RDMA IRQ vector affinity settings query
issue, the patch provides the correct mlx5_core implementation for RDMA to
correctly query vector affinity.
I sent this patch privately to Sagi a week a go, so he could to test it
but I didn't hear from him.
All other patches are trivial misc fixes.
Please pull and let me know if there's any problem.
for -stable v4.14-y and later:
("net/mlx5: Fix get vector affinity helper function")
("{net,ib}/mlx5: Don't disable local loopback multicast traffic when needed")
Note: Merging this series with net-next will produce the following conflict:
<<<<<<< HEAD

1) Don't allow to change the encap type on state updates.
The encap type is set on state initialization and
should not change anymore. From Herbert Xu.
2) Skip dead policies when rehashing to fix a
slab-out-of-bounds bug in xfrm_hash_rebuild.
From Florian Westphal.
3) Two buffer overread fixes in pfkey.
From Eric Biggers.
4) Fix rcu usage in xfrm_get_type_offload,
request_module can sleep, so can't be used
under rcu_read_lock. From Sabrina Dubroca.
5) Fix an uninitialized lock in xfrm_trans_queue.
Use __skb_queue_tail instead of skb_queue_tail
in xfrm_trans_queue as we don't need the lock.
From Herbert Xu.
6) Currently it is possible to create an xfrm state with an
unknown encap type in ESP IPv4. Fix this by returning an
error on unknown encap types. Also from Herbert Xu.
7) Fix sleeping inside a spinlock in xfrm_policy_cache_flush.
From Florian Westphal.
8) Fix ESP GRO when the headers not fully in the linear part
of the skb. We need to pull before we can access them.
9) Fix a skb leak on error in key_notify_policy.
10) Fix a race in the xdst pcpu cache, we need to
run the resolver routines with bottom halfes
off like the old flowcache did.

The fix for handling two-finger scroll (i4a646580f793 - "Input: ALPS -
fix two-finger scroll breakage in right side on ALPS touchpad")
introduced a minor "typo" that broke decoding of multi-touch events are
decoded on some ALPS touchpads. For example, tapping with three-fingers
can no longer be used to emulate middle-mouse-button (the kernel doesn't
recognize this as the proper event, and doesn't report it correctly to
userspace). This affects touchpads that use SS4 "plus" protocol
variant, like those found on Dell E7270 & E7470 laptops (tested on
E7270).
First, probably the code in alps_decode_ss4_v2() for case
SS4_PACKET_ID_MULTI used inconsistent indices to "f->mt[]". You can see
0 & 1 are used for the "if" part but 2 & 3 are used for the "else" part.
Second, in the previous patch, new macros were introduced to decode X
coordinates specific to the SS4 "plus" variant, but the macro to
define the maximum X value wasn't changed accordingly. The macros to
decode X values for "plus" variant are effectively shifted right by 1
bit, but the max wasn't shifted too. This causes the driver to
incorrectly handle "no data" cases, which also interfered with how
multi-touch was handled.

dev->features is not changed on success and checks for diffs between

because of the driver override).
The solution is to keep track of successful/failed feature changes and

Enable the use of -mindirect-branch=thunk-extern in newer GCC, and provide
the corresponding thunks. Provide assembler macros for invoking the thunks
in the same way that GCC does, from native and inline assembler.
This adds X86_FEATURE_RETPOLINE and sets it by default on all CPUs. In
some circumstances, IBRS microcode features may be used instead, and the
retpoline can be disabled.
On AMD CPUs if lfence is serialising, the retpoline can be dramatically
simplified to a simple "lfence; jmp *\reg". A future patch, after it has
been verified that lfence really is serialising in all circumstances, can
enable this by setting the X86_FEATURE_RETPOLINE_AMD feature bit in addition
to X86_FEATURE_RETPOLINE.
Do not align the retpoline in the altinstr section, because there is no
guarantee that it stays aligned when it's copied over the oldinstr during
alternative patching.

There are systems platform information management interfaces (such as
HOST2BMC) for which we cannot disable local loopback multicast traffic.
Separate disable_local_lb_mc and disable_local_lb_uc capability bits so
driver will not disable multicast loopback traffic if not supported.
(It is expected that Firmware will not set disable_local_lb_mc if
HOST2BMC is running for example.)
Function mlx5_nic_vport_update_local_lb will do best effort to
disable/enable UC/MC loopback traffic and return success only in case it
succeeded to changed all allowed by Firmware.
Adapt mlx5_ib and mlx5e to support the new cap bits.

Avoid problems with BIOS implementations which don't report all used
resources to the OS by only allocating a 256GB window directly below the
hardware limit (from the BKDG, sec 2.4.6).
Fixes a silent reboot loop reported by Aaro Koskinen <[email protected]>
on an AMD-based MSI MS-7699/760GA-P43(FX) system. This was apparently
caused by RAM or other unreported hardware that conflicted with the new
window.

When using a GPIO which is high by default, and initialize the
driver in USB Hub mode, initialization fails with:
[ 111.757794] usb3503 0-0008: SP_ILOCK failed (-5)
The reason seems to be that the chip is not properly reset.
Probe does initialize reset low, however some lines later the
code already set it back high, which is not long enouth.
Make sure reset is asserted for at least 100us by inserting a
delay after initializing the reset pin during probe.

Only try to enable a 64-bit window on AMD CPUs when "pci=big_root_window"
is specified.
This taints the kernel because the new 64-bit window uses address space we
don't know anything about, and it may contain unreported devices or memory
that would conflict with the window.
The pci_amd_enable_64bit_bar() quirk that enables the window is specific to
AMD CPUs. The generic solution would be to have the firmware enable the
window and describe it in the host bridge's _CRS method, or at least
describe it in the _PRS method so the OS would have the option of enabling
it.

This reverts commits ae1f576707
and ac9b305caa.
If the hardware doesn't support MOVBE, but L0 sets CPUID.01H:ECX.MOVBE
in L1's emulated CPUID information, then L1 is likely to pass that
CPUID bit through to L2. L2 will expect MOVBE to work, but if L1
doesn't intercept #UD, then any MOVBE instruction executed in L2 will
raise #UD, and the exception will be delivered in L2.
Commit ac9b305caa is a better and more
complete version of ae1f576707 ("KVM: nVMX: Do not emulate #UD while
in guest mode"); however, neither considers the above case.

The ALSA sequencer ioctls have no protection against racy calls while
the concurrent operations may lead to interfere with each other. As
reported recently, for example, the concurrent calls of setting client
pool with a combination of write calls may lead to either the
unkillable dead-lock or UAF.
As a slightly big hammer solution, this patch introduces the mutex to
make each ioctl exclusive. Although this may reduce performance via
parallel ioctl calls, usually it's not demanded for sequencer usages,
hence it should be negligible.
