age is signed integer, so result can be negative when the timestamps have a large delta. In this case we want to discard the entry. Instead of using age >= 2 || age < 0, just make it unsigned. Fixes: b36e4523 ("netfilter: nf_conncount: fix garbage collection confirm race") Reviewed-by:

Most of the time these were the same value anyway, but when CONFIG_LOCKDEP was enabled we would use a smaller number of locks to reduce overhead. Unfortunately having two values is confusing and not worth the complexity. This fixes a bug where tree_gc_worker() would only GC up to CONNCOUNT_LOCK_SLOTS trees which meant when CONFIG_LOCKDEP was enabled not all trees would be GCed by tree_gc_worker(). Fixes: 5c789e13 ("netfilter: nf_conncount: Add list lock and gc worker, and RCU for init tree search") Signed-off-by:

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() ...

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

Pull audit updates from Paul Moore: "In the finest of holiday of traditions, I have a number of gifts to share today. 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.

Pull x86 asm updates from Ingo Molnar: "Two changes: - Remove (some) remnants of the vDSO's fake section table mechanism that were left behind when the vDSO build process reverted to using "objdump -S" to strip the userspace image. - Remove hardcoded POPCNT mnemonics now that the minimum binutils version supports the symbolic form" * 'x86-asm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/vdso: Remove a stale/misleading comment from the linker script x86/vdso: Remove obsolete "fake section table" reservation x86: Use POPCNT mnemonics in arch_hweight.h

Pull x86 AMD northbridge updates from Ingo Molnar: "Update DF/SMN access and k10temp for AMD F17h M30h, by Brian Woods: 'Updates the data fabric/system management network code needed to get k10temp working for M30h. Since there are now processors which have multiple roots per DF/SMN interface, there needs to some logic which skips N-1 root complexes per DF/SMN interface. This is because the root complexes per interface are redundant (as far as DF/SMN goes). These changes shouldn't effect past processors and, for F17h M0Xh, the mappings stay the same.' The hwmon changes were seen and acked by hwmon maintainer Guenter Roeck" * 'x86-amd-nb-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: hwmon/k10temp: Add support for AMD family 17h, model 30h CPUs x86/amd_nb: Add PCI device IDs for family 17h, model 30h x86/amd_nb: Add support for newer PCI topologies hwmon/k10temp, x86/amd_nb: Consolidate shared device IDs

Pull scheduler updates from Ingo Molnar: "The main changes in this cycle were: - Introduce "Energy Aware Scheduling" - by Quentin Perret. This is a coherent topology description of CPUs in cooperation with the PM subsystem, with the goal to schedule more energy-efficiently on asymetric SMP platform - such as waking up tasks to the more energy-efficient CPUs first, as long as the system isn't oversubscribed. For details of the design, see: https://lore.kernel.org/lkml/20180724122521.22109-1-quentin.perret@arm.com/ - Misc cleanups and smaller enhancements" * 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (23 commits) sched/fair: Select an energy-efficient CPU on task wake-up sched/fair: Introduce an energy estimation helper function sched/fair: Add over-utilization/tipping point indicator sched/fair: Clean-up update_sg_lb_stats parameters sched/toplogy: Introduce the 'sched_energy_present' static key sched/topology: Make Energy Aware Scheduling depend on schedutil sched/topology: Disable EAS on inappropriate platforms sched/topology: Add lowest CPU asymmetry sched_domain level pointer sched/topology: Reference the Energy Model of CPUs when available PM: Introduce an Energy Model management framework sched/cpufreq: Prepare schedutil for Energy Aware Scheduling sched/topology: Relocate arch_scale_cpu_capacity() to the internal header sched/core: Remove unnecessary unlikely() in push_*_task() sched/topology: Remove the ::smt_gain field from 'struct sched_domain' sched: Fix various typos in comments sched/core: Clean up the #ifdef block in add_nr_running() sched/fair: Make some variables static sched/core: Create task_has_idle_policy() helper sched/fair: Add lsub_positive() and use it consistently sched/fair: Mask UTIL_AVG_UNCHANGED usages ...
