      ====================
      Netfilter updates for net-next
      
      The following patchset contains Netfilter updates for your net-next tree:
      
      1) Support for transparent proxying for nf_tables, from Mate Eckl.
      
      2) Patchset to add OS passive fingerprint recognition for nf_tables,
         from Fernando Fernandez. This takes common code from xt_osf and
         place it into the new nfnetlink_osf module for codebase sharing.
      
      3) Lightweight tunneling support for nf_tables.
      
      4) meta and lookup are likely going to be used in rulesets, make them
         direct calls. From Florian Westphal.
      
      A bunch of incremental updates:
      
      5) use PTR_ERR_OR_ZERO() from nft_numgen, from YueHaibing.
      
      6) Use kvmalloc_array() to allocate hashtables, from Li RongQing.
      
      7) Explicit dependencies between nfnetlink_cttimeout and conntrack
         timeout extensions, from Harsha Sharma.
      
      8) Simplify NLM_F_CREATE handling in nf_tables.
      
      9) Removed unused variable in the get element command, from
         YueHaibing.
      
      10) Expose bridge hook priorities through uapi, from Mate Eckl.
      
      And a few fixes for previous Netfilter batch for net-next:
      
      11) Use per-netns mutex from flowtable event, from Florian Westphal.
      
      12) Remove explicit dependency on iptables CT target from conntrack
          zones, from Florian.
      
      13) Fix use-after-free in rmmod nf_conntrack path, also from Florian.

           the wrong bit, which caused timers to either expire late or stop

      Partially revert "block: fail op_is_write() requests to read-only partitions" · a32e236e
      Linus Torvalds authored
      It turns out that commit 721c7fc7 ("block: fail op_is_write()
      requests to read-only partitions"), while obviously correct, causes
      problems for some older lvm2 installations.
      
      The reason is that the lvm snapshotting will continue to write to the
      snapshow COW volume, even after the volume has been marked read-only.
      End result: snapshot failure.
      
      This has actually been fixed in newer version of the lvm2 tool, but the
      old tools still exist, and the breakage was reported both in the kernel
      bugzilla and in the Debian bugzilla:
      
        https://bugzilla.kernel.org/show_bug.cgi?id=200439
        https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900442
      
      The lvm2 fix is here
      
        https://sourceware.org/git/?p=lvm2.git;a=commit;h=a6fdb9d9d70f51c49ad11a87ab4243344e6701a3
      
      but until everybody has updated to recent versions, we'll have to weaken
      the "never write to read-only partitions" check.  It now allows the
      write to happen, but causes a warning, something like this:

      Note that this is a "revert" in behavior only.  I'm leaving alone the
      actual code cleanups in commit 721c7fc7, but letting the previously
      uncaught request go through with a warning instead of stopping it.

      netlink: Don't shift on 64 for ngroups · 91874ecf
      Dmitry Safonov authored
      It's legal to have 64 groups for netlink_sock.
      
      As user-supplied nladdr->nl_groups is __u32, it's possible to subscribe
      only to first 32 groups.
      
      The check for correctness of .bind() userspace supplied parameter
      is done by applying mask made from ngroups shift. Which broke Android
      as they have 64 groups and the shift for mask resulted in an overflow.

         allocator since driver will recycle frame anyway in case of an
         error, from Jakub.
      
      3) Fix up BPF test_lwt_seg6local test cases to final iproute2
         syntax, from Mathieu.
