Pull networking updates from David Miller:
1) New ipset extensions for matching on destination MAC addresses, from
Stefano Brivio.
2) Add ipv4 ttl and tos, plus ipv6 flow label and hop limit offloads to
nfp driver. From Stefano Brivio.
3) Implement GRO for plain UDP sockets, from Paolo Abeni.
4) Lots of work from Michał Mirosław to eliminate the VLAN_TAG_PRESENT
bit so that we could support the entire vlan_tci value.
5) Rework the IPSEC policy lookups to better optimize more usecases,
from Florian Westphal.
6) Infrastructure changes eliminating direct manipulation of SKB lists
wherever possible, and to always use the appropriate SKB list
helpers. This work is still ongoing...
7) Lots of PHY driver and state machine improvements and
simplifications, from Heiner Kallweit.
8) Various TSO deferral refinements, from Eric Dumazet.
9) Add ntuple filter support to aquantia driver, from Dmitry Bogdanov.
10) Batch dropping of XDP packets in tuntap, from Jason Wang.
11) Lots of cleanups and improvements to the r8169 driver from Heiner
Kallweit, including support for ->xmit_more. This driver has been
getting some much needed love since he started working on it.
12) Lots of new forwarding selftests from Petr Machata.
13) Enable VXLAN learning in mlxsw driver, from Ido Schimmel.
14) Packed ring support for virtio, from Tiwei Bie.
15) Add new Aquantia AQtion USB driver, from Dmitry Bezrukov.
16) Add XDP support to dpaa2-eth driver, from Ioana Ciocoi Radulescu.
17) Implement coalescing on TCP backlog queue, from Eric Dumazet.
18) Implement carrier change in tun driver, from Nicolas Dichtel.
19) Support msg_zerocopy in UDP, from Willem de Bruijn.
20) Significantly improve garbage collection of neighbor objects when
the table has many PERMANENT entries, from David Ahern.
21) Remove egdev usage from nfp and mlx5, and remove the facility
completely from the tree as it no longer has any users. From Oz
Shlomo and others.
22) Add a NETDEV_PRE_CHANGEADDR so that drivers can veto the change and
therefore abort the operation before the commit phase (which is the
NETDEV_CHANGEADDR event). From Petr Machata.
23) Add indirect call wrappers to avoid retpoline overhead, and use them
in the GRO code paths. From Paolo Abeni.
24) Add support for netlink FDB get operations, from Roopa Prabhu.
25) Support bloom filter in mlxsw driver, from Nir Dotan.
26) Add SKB extension infrastructure. This consolidates the handling of
the auxiliary SKB data used by IPSEC and bridge netfilter, and is
designed to support the needs to MPTCP which could be integrated in
the future.
27) Lots of XDP TX optimizations in mlx5 from Tariq Toukan.

Pull selinux patches from Paul Moore: "I already used my best holiday pull request lines in the audit pull request, so this one is going to be a bit more boring, sorry about that. To make up for this, we do have a birthday of sorts to celebrate: SELinux turns 18 years old this December. Perhaps not the most exciting thing in the world for most people, but I think it's safe to say that anyone reading this email doesn't exactly fall into the "most people" category. Back to business and the pull request itself: Ondrej has five patches in this pull request and I lump them into three categories: one patch to always allow submounts (using similar logic to elsewhere in the kernel), one to fix some issues with the SELinux policydb, and the others to cleanup and improve the SELinux sidtab. The other patches from Alexey and Petr and trivial fixes that are adequately described in their respective subject lines. With this last pull request of the year, I want to thank everyone who has contributed patches, testing, and reviews to the SELinux project this year, and the past 18 years. Like any good open source effort, SELinux is only as good as the community which supports it, and I'm very happy that we have the community we do - thank you all!" * tag 'selinux-pr-20181224' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: overhaul sidtab to fix bug and improve performance selinux: use separate table for initial SID lookup selinux: make "selinux_policycap_names[]" const char * selinux: always allow mounting submounts selinux: refactor sidtab conversion Documentation: Update SELinux reference policy URL selinux: policydb - fix byte order and alignment issues
