 "Highlights:

   - Gustavo A. R. Silva keeps working on the implicit switch fallthru
     changes.

   - Support 802.11ax High-Efficiency wireless in cfg80211 et al, From
     Luca Coelho.

   - Add virtual XFRM interfaces, which avoids all of the limitations of
     existing IPSEC tunnels. From Steffen Klassert.

   - Convert GRO over to use a hash table, so that when we have many
     flows active we don't traverse a long list during accumluation.

   - Many new self tests for routing, TC, tunnels, etc. Too many
     contributors to mention them all, but I'm really happy to keep
     seeing this stuff.

2018-08-14T20:07:22+00:00

Pull LED updates from Jacek Anaszewski:
 "LED triggers improvements make the biggest part of this pull request.
  The most striking ones, that allowed for nice cleanups in the triggers
  are:

   - centralized handling of creation and removal of trigger sysfs
     attributes via attribute group

   - addition of module_led_trigger() helper

  The other things that need to be mentioned:

  New features and improvements to existing LED class drivers:

   - lt3593: add DT support, switch to gpiod interface

   - lm3692x: support LED sync configuration, change OF calls to fwnode
     calls

   - apu: modify PC Engines apu/apu2 driver to support apu3

  Change in the drivers/net/can/led.c:

   - mark led trigger as broken since it's in the way for the further
     cleanups. It implements a subset of the netdev trigger and an Ack
     is needed from someone who can actually test and confirm that the
     netdev trigger works for can devices"

Bluetooth: hidp: buffer overflow in hidp_process_report

2018-08-01T07:12:35+00:00

CVE-2018-9363

The buffer length is unsigned at all layers, but gets cast to int and
checked in hidp_process_report and can lead to a buffer overflow.
Switch len parameter to unsigned int to resolve issue.

This affects 3.18 and newer kernels.

Bluetooth: Handle ADv set terminated event

2018-07-30T11:44:53+00:00

This event comes after connection complete event for incoming
connections. Since we now have different random address for
each instance, conn resp address is assigned from this event.

As of now only connection part is handled as we are not
enabling duration or max num of events while starting ext adv.

Bluetooth: Implement Set ADV set random address

2018-07-30T11:44:53+00:00

This basically sets the random address for the adv instance
Random address can be set only if the instance is created which
is done in Set ext adv param.

Random address and rpa expire timer and flags have been added
to adv instance which will be used when the respective
instance is scheduled.

This introduces a hci_get_random_address() which returns the
own address type and random address (rpa or nrpa) based
on the instance flags and hdev flags. New function is required
since own address type should be known before setting adv params
but address can be set only after setting params.
