      Fix call trace when interrupts are disabled while sleeping function kzalloc is called · 5f77898d
      Shyam Iyer authored
      request_threaded irq will call kzalloc that can sleep. Initializing the flags variable outside of spin_lock_irqsave/restore in bnad_mbox_irq_alloc will avoid call traces like below.

      Calling icmp_send() on a local message size error leads to

      ipv4: Don't use ufo handling on later transformed packets · c146066a
      Steffen Klassert authored
      We might call ip_ufo_append_data() for packets that will be IPsec
      transformed later. This function should be used just for real
      udp packets. So we check for rt->dst.header_len which is only
      nonzero on IPsec handling and call ip_ufo_append_data() just
      if rt->dst.header_len is zero.

      ipv6: Don't put artificial limit on routing table size. · 957c665f
      David S. Miller authored
      IPV6, unlike IPV4, doesn't have a routing cache.
      
      Routing table entries, as well as clones made in response
      to route lookup requests, all live in the same table.  And
      all of these things are together collected in the destination
      cache table for ipv6.
      
      This means that routing table entries count against the garbage
      collection limits, even though such entries cannot ever be reclaimed
      and are added explicitly by the administrator (rather than being
      created in response to lookups).
      
      Therefore it makes no sense to count ipv6 routing table entries
      against the GC limits.
      
      Add a DST_NOCOUNT destination cache entry flag, and skip the counting
      if it is set.  Use this flag bit in ipv6 when adding routing table
      entries.

      6pack,mkiss: fix lock inconsistency · 6e4e2f81

      Lockdep found a locking inconsistency in the mkiss_close function:

      The message hints that disc_data_lock is aquired with softirqs disabled,
      but does not itself disable softirqs, which can in rare circumstances
      lead to a deadlock. 
      The same problem is present in the 6pack driver, this patch fixes both
      by using write_lock_bh instead of write_lock.
