      ipv6: fix a potential deadlock in do_ipv6_setsockopt() · 8651be8f
      WANG Cong authored
      Baozeng reported this deadlock case:
      
             CPU0                    CPU1
             ----                    ----
        lock([  165.136033] sk_lock-AF_INET6);
                                     lock([  165.136033] rtnl_mutex);
                                     lock([  165.136033] sk_lock-AF_INET6);
        lock([  165.136033] rtnl_mutex);
      
      Similar to commit 87e9f031
      ("ipv4: fix a potential deadlock in mcast getsockopt() path")
      this is due to we still have a case, ipv6_sock_mc_close(),
      where we acquire sk_lock before rtnl_lock. Close this deadlock
      with the similar solution, that is always acquire rtnl lock first.
      
      Fixes: baf606d9 ("ipv4,ipv6: grab rtnl before locking the socket")

      ====================
      Netfilter fixes for net
      
      The following patchset contains Netfilter fixes for your net tree,
      they are:
      
      1) Fix compilation warning in xt_hashlimit on m68k 32-bits, from
         Geert Uytterhoeven.
      
      2) Fix wrong timeout in set elements added from packet path via
         nft_dynset, from Anders K. Pedersen.
      
      3) Remove obsolete nf_conntrack_events_retry_timeout sysctl
         documentation, from Nicolas Dichtel.
      
      4) Ensure proper initialization of log flags via xt_LOG, from
         Liping Zhang.
      
      5) Missing alias to autoload ipcomp, also from Liping Zhang.
      
      6) Missing NFTA_HASH_OFFSET attribute validation, again from Liping.
      
      7) Wrong integer type in the new nft_parse_u32_check() function,
         from Dan Carpenter.
      
      8) Another wrong integer type declaration in nft_exthdr_init, also
         from Dan Carpenter.
      
      9) Fix insufficient mode validation in nft_range.
      
      10) Fix compilation warning in nft_range due to possible uninitialized
          value, from Arnd Bergmann.
      
      11) Zero nf_hook_ops allocated via xt_hook_alloc() in x_tables to
          calm down kmemcheck, from Florian Westphal.
      
      12) Schedule gc_worker() to run again if GC_MAX_EVICTS quota is reached,
          from Nicolas Dichtel.
      
      13) Fix nf_queue() after conversion to single-linked hook list, related
          to incorrect bypass flag handling and incorrect hook point of
          reinjection.

      kexec: Export kexec_in_progress to modules · 97dcaa0f
      Florian Fainelli authored
      The bcm_sf2 driver uses kexec_in_progress to know whether it can power
      down an integrated PHY during shutdown, and can be built as a module.
      Other modules may be using this in the future, so export it.
      
      Fixes: 2399d614 ("net: dsa: bcm_sf2: Prevent GPHY shutdown for kexec'd kernels")
