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. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1845 commits) net: dccp: fix kernel crash on module load drivers/net: appletalk/cops: remove redundant if statement and mask bnx2x: Fix NULL pointer dereference in bnx2x_del_all_vlans() on some hw net/net_namespace: Check the return value of register_pernet_subsys() net/netlink_compat: Fix a missing check of nla_parse_nested ieee802154: lowpan_header_create check must check daddr net/mlx4_core: drop useless LIST_HEAD mlxsw: spectrum: drop useless LIST_HEAD net/mlx5e: drop useless LIST_HEAD iptunnel: Set tun_flags in the iptunnel_metadata_reply from src net/mlx5e: fix semicolon.cocci warnings staging: octeon: fix build failure with XFRM enabled net: Revert recent Spectre-v1 patches. can: af_can: Fix Spectre v1 vulnerability packet: validate address length if non-zero nfc: af_nfc: Fix Spectre v1 vulnerability phonet: af_phonet: Fix Spectre v1 vulnerability net: core: Fix Spectre v1 vulnerability net: minor cleanup in skb_ext_add() net: drop the unused helper skb_ext_get() ...

git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux 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

While most of them are re-gifts from others, unlike the typical re-gift, these are things you will want in and around your tree; I promise. This pull request is perhaps a bit larger than our typical PR, but most of it comes from Jan's rework of audit's fanotify code; a very welcome improvement. We ran this through our normal regression tests, as well as some newly created stress tests and everything looks good. Richard added a few patches, mostly cleaning up a few things and and shortening some of the audit records that we send to userspace; a change the userspace folks are quite happy about. Finally YueHaibing and I kick in a few patches to simplify things a bit and make the code less prone to errors. Lastly, I want to say thanks one more time to everyone who has contributed patches, testing, and code reviews for the audit subsystem over the past year.

Mostly useful to shrink the kernel & as preparation for nanoMIPS support which does not yet include FP. - MIPS SIMD Architecture (MSA) vector register context is now exposed by ptrace via a new NT_MIPS_MSA regset. - ASIDs are now stored as 64b values even for MIPS32 kernels, expanding the ASID version field sufficiently that we don't need to worry about overflow & avoiding rare issues with reused ASIDs that have been observed in the wild. - The branch delay slot "emulation" page is now mapped without write permission for the user, preventing its use as a nice location for attacks to execute malicious code from. - Support for ioremap_prot(), primarily to allow gdb or other ptrace users the ability to view their tracee's memory using the same cache coherency attribute. - Optimizations to more cpu_has_* macros, allowing more to be compile-time constant where possible. - Enable building the whole kernel with UBSAN instrumentation. - Enable building the kernel with link-time dead code & data elimination. Platform specific changes include: - The Boston board gains a workaround for DMA prefetching issues with the EG20T Platform Controller Hub that it uses. - Cleanups to Cavium Octeon code removing about 20k lines of redundant code, mostly unused or duplicate register definitions in headers. - defconfig updates for the DECstation machines, including new defconfigs for r4k & 64b machines. - Further work on Loongson 3 support. - DMA fixes for SiByte machines" * tag 'mips_4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: (95 commits) MIPS: math-emu: Write-protect delay slot emulation pages MIPS: Remove struct mm_context_t fp_mode_switching field mips: generate uapi header and system call table files mips: add system call table generation support mips: remove syscall table entries mips: add +1 to __NR_syscalls in uapi header mips: rename scall64-64.S to scall64-n64.S mips: remove unused macros mips: add __NR_syscalls along with __NR_Linux_syscalls MIPS: Expand MIPS32 ASIDs to 64 bits MIPS: OCTEON: delete redundant register definitions MIPS: OCTEON: cvmx_gmxx_inf_mode: use oldest forward compatible definition MIPS: OCTEON: cvmx_mio_fus_dat3: use oldest forward compatible definition MIPS: OCTEON: cvmx_pko_mem_debug8: use oldest forward compatible definition MIPS: OCTEON: octeon-usb: use common gpio_bit definition MIPS: OCTEON: enable all OCTEON drivers in defconfig mips: annotate implicit fall throughs MIPS: Hardcode cpu_has_mips* where target ISA allows MIPS: MT: Remove norps command line parameter MIPS: Only include mmzone.h when CONFIG_NEED_MULTIPLE_NODES=y ...

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This round is dominated by NXP's i.MX clk drivers. We gained support for two or three i.MX SoCs in here and that mostly means a lot of driver code and data. Beyond that platform, there are some new Mediatek, Amlogic, and Qualcomm clk drivers added in here, and then we get to the long tail of driver updates and non-critical fixes all around, including code for vendors such as Renesas, Rockchip, Nvidia, and Allwinner. Overall, the driver updates look normal. Apart from the usual driver updates we have an update to make registering OF based clk providers a little simpler when they're devices created as a child of a device backed by a node in DT. Drivers don't have to jump through hoops to unregister the provider upon driver removal anymore because the API does the right thing and uses the parent device DT node.
