      Pull networking fixes from David Miller:
       "It looks like a sizeble collection but this is nearly 3 weeks of bug
        fixing while you were away.
      
         1) Fix crashes over IPSEC tunnels with NAT, the latter can reroute
            the packet through a non-IPSEC protected path and the code has to
            be able to handle SKBs attached to routes lacking an attached xfrm
            state.  From Steffen Klassert.
      
         2) Fix OOPSs in ipv4 and ipv6 ipsec layers for unsupported
            sub-protocols, also from Steffen Klassert.
      
         3) Set local_df on fragmented netfilter skbs otherwise we won't be
            able to forward successfully, from Florian Westphal.
      
         4) cdc_mbim ipv6 neighbour code does __vlan_find_dev_deep without
            holding RCU lock, from Bjorn Mork.
      
         5) local_df test in ip_may_fragment is inverted, from Florian
            Westphal.
      
         6) jme driver doesn't check for DMA mapping failures, from Neil
            Horman.
      
         7) qlogic driver doesn't calculate number of TX queues properly, from
            Shahed Shaikh.
      
         8) fib_info_cnt can drift irreversibly positive if we fail to
            allocate the fi->fib_metrics array, from Sergey Popovich.
      
         9) Fix use after free in ip6_route_me_harder(), also from Sergey
            Popovich.
      
        10) When SYSCTL is disabled, we don't handle local_port_range and
            ping_group_range defaults properly at all, from Cong Wang.
      
        11) Unaccelerated VLAN tagged frames improperly handled by cdc_mbim
            driver, fix from Bjorn Mork.
      
        12) cassini driver needs nested lock annotations for TX locking, from
            Emil Goode.
      
        13) On init error ipv6 VTI driver can unregister pernet ops twice,
            oops.  Fix from Mahtias Krause.
      
        14) If macvlan device is down, don't propagate IFF_ALLMULTI changes,
            from Peter Christensen.
      
        15) Missing NULL pointer check while parsing netlink config options in
            ip6_tnl_validate().  From Susant Sahani.
      
        16) Fix handling of neighbour entries during ipv6 router reachability
            probing, from Duan Jiong.
      
        17) x86 and s390 JIT address randomization has some address
            calculation bugs leading to crashes, from Alexei Starovoitov and
            Heiko Carstens.
      
        18) Clear up those uglies with nop patching and net_get_random_once(),
            from Hannes Frederic Sowa.
      
        19) Option length miscalculated in ip6_append_data(), fix also from
            Hannes Frederic Sowa.
      
        20) A while ago we fixed a race during device unregistry when a
            namespace went down, turns out there is a second place that needs
            similar protection.  From Cong Wang.
      
        21) In the new Altera TSE driver multicast filtering isn't working,
            disable it and just use promisc mode until the cause is found.
            From Vince Bridgers.
      
        22) When we disable router enabling in ipv6 we have to flush the
            cached routes explicitly, from Duan Jiong.
      
        23) NBMA tunnels should not cache routes on the tunnel object because
            the key is variable, from Timo Teräs.
      
        24) With stacked devices GRO information in skb->cb[] can be not setup
            properly, make sure it is in all code paths.  From Eric Dumazet.
      
        25) Really fix stacked vlan locking, multiple levels of nesting with
            intervening non-vlan devices are possible.  From Vlad Yasevich.
      
        26) Fallback ipip tunnel device's mtu is not setup properly, from
            Steffen Klassert.
      
        27) The packet scheduler's tcindex filter can crash because we
            structure copy objects with list_head's inside, oops.  From Cong
            Wang.
      
        28) Fix CHECKSUM_COMPLETE handling for ipv6 GRE tunnels, from Eric
            Dumazet.
      
        29) In some configurations 'itag' in __mkroute_input() can end up
            being used uninitialized because of how fib_validate_source()
            works.  Fix it by explitly initializing itag to zero like all the
            other fib_validate_source() callers do, from Li RongQing"

      Prior to commit 42661299 ("[media] DocBook: Move all media docbook

      (or more) book(s) by calling, for example
      
          make htmldocs DOCBOOKS=80211.xml
      
      This now fails:

      Ignore errors from that copy to make this possible again.

      mm/memory-failure.c: fix memory leak by race between poison and unpoison · 3e030ecc
      Naoya Horiguchi authored
      When a memory error happens on an in-use page or (free and in-use)
      hugepage, the victim page is isolated with its refcount set to one.
      
      When you try to unpoison it later, unpoison_memory() calls put_page()
      for it twice in order to bring the page back to free page pool (buddy or
      free hugepage list).  However, if another memory error occurs on the
      page which we are unpoisoning, memory_failure() returns without
      releasing the refcount which was incremented in the same call at first,
      which results in memory leak and unconsistent num_poisoned_pages
      statistics.  This patch fixes it.

      memcg: fix swapcache charge from kernel thread context · 6f6acb00
      Michal Hocko authored
      Commit 284f39af ("mm: memcg: push !mm handling out to page cache
      charge function") explicitly checks for page cache charges without any
      mm context (from kernel thread context[1]).
      
      This seemed to be the only possible case where memory could be charged
      without mm context so commit 03583f1a ("memcg: remove unnecessary
      !mm check from try_get_mem_cgroup_from_mm()") removed the mm check from
      get_mem_cgroup_from_mm().  This however caused another NULL ptr
      dereference during early boot when loopback kernel thread splices to
      tmpfs as reported by Stephan Kulow:

      This patch fixes the issue by reintroducing mm check into

      __mem_cgroup_try_charge_swapin as we do for the regular page cache path
      but it is not worth troubles.  The check is not that expensive and it is
      better to have get_mem_cgroup_from_mm more robust.

      mm: madvise: fix MADV_WILLNEED on shmem swapouts · 55231e5c
      Johannes Weiner authored
      MADV_WILLNEED currently does not read swapped out shmem pages back in.
      
      Commit 0cd6144a ("mm + fs: prepare for non-page entries in page
      cache radix trees") made find_get_page() filter exceptional radix tree
      entries but failed to convert all find_get_page() callers that WANT
      exceptional entries over to find_get_entry().  One of them is shmem swap
      readahead in madvise, which now skips over any swap-out records.
      
      Convert it to find_get_entry().

      mm/filemap.c: avoid always dirtying mapping->flags on O_DIRECT · 7fcbbaf1
      Jens Axboe authored
      In some testing I ran today (some fio jobs that spread over two nodes),
      we end up spending 40% of the time in filemap_check_errors().  That
      smells fishy.  Looking further, this is basically what happens:
      
      blkdev_aio_read()
          generic_file_aio_read()
              filemap_write_and_wait_range()
                  if (!mapping->nr_pages)
                      filemap_check_errors()
      
      and filemap_check_errors() always attempts two test_and_clear_bit() on
      the mapping flags, thus dirtying it for every single invocation.  The
      patch below tests each of these bits before clearing them, avoiding this
      issue.  In my test case (4-socket box), performance went from 1.7M IOPS
      to 4.0M IOPS.

      hwpoison, hugetlb: lock_page/unlock_page does not match for handling a free hugepage · b985194c
      Chen Yucong authored
      For handling a free hugepage in memory failure, the race will happen if
      another thread hwpoisoned this hugepage concurrently.  So we need to
      check PageHWPoison instead of !PageHWPoison.
      
      If hwpoison_filter(p) returns true or a race happens, then we need to
      unlock_page(hpage).

      parisc: 'renameat2()' doesn't need (or have) a separate compat system call · 9abd09ac
      Linus Torvalds authored
      The 'renameat2()' system call was incorrectly added as a ENTRY_COMP() in
      the parisc system call table by commit 18e480aa ("parisc: add
      renameat2 syscall").  That causes a link-time error due to there not
      being any compat version of that system call:
      
        arch/parisc/kernel/built-in.o: In function `sys_call_table':
        (.rodata+0xad0): undefined reference to `compat_sys_renameat2'
        make: *** [vmlinux] Error 1
      
      Easily fixed by marking the system call as being the same for compat as
      for native by using ENTRY_SAME() instead of ENTRY_COMP().
