      ====================
      here's a bigger pull request for 4.4. The diffstat looks scary as we
      created a new directory realtek for all realtek drivers. In the future
      I'm planning to create similar directories for all vendors, currently we
      just have ath, mediatek and realtek. This change has been in linux-next
      for a couple of weeks so it should be safe, but of course you never
      know.
      
      There's also a new driver rtl8xxxu for few realtek USB devices. This
      just made it to the last linux-next build.
      
      Otherwise there's nothing really special, more info below. If time
      permits, and it's ok for you, I'm hoping to send you a one more pull
      request this week.

      seccomp, ptrace: add support for dumping seccomp filters · f8e529ed
      Tycho Andersen 提交于
      This patch adds support for dumping a process' (classic BPF) seccomp
      filters via ptrace.
      
      PTRACE_SECCOMP_GET_FILTER allows the tracer to dump the user's classic BPF
      seccomp filters. addr should be an integer which represents the ith seccomp
      filter (0 is the most recently installed filter). data should be a struct
      sock_filter * with enough room for the ith filter, or NULL, in which case
      the filter is not saved. The return value for this command is the number of
      BPF instructions the program represents, or negative in the case of errors.
      Command specific errors are ENOENT: which indicates that there is no ith
      filter in this seccomp tree, and EMEDIUMTYPE, which indicates that the ith
      filter was not installed as a classic BPF filter.
      
      A caveat with this approach is that there is no way to get explicitly at
      the heirarchy of seccomp filters, and users need to memcmp() filters to
      decide which are inherited. This means that a task which installs two of
      the same filter can potentially confuse users of this interface.
      
      v2: * make save_orig const
          * check that the orig_prog exists (not necessary right now, but when
             grows eBPF support it will be)
          * s/n/filter_off and make it an unsigned long to match ptrace
          * count "down" the tree instead of "up" when passing a filter offset
      
      v3: * don't take the current task's lock for inspecting its seccomp mode
          * use a 0x42** constant for the ptrace command value
      
      v4: * don't copy to userspace while holding spinlocks
      
      v5: * add another condition to WARN_ON
      
      v6: * rebase on net-next

      ====================
      mpls: mulipath improvements
      
      Two improvements to the recently added mpls multipath support. The
      first is a fix for missing initialisation the nexthop address length
      for the v4 and v6 explicit null label routes, and the second is to
      reduce the amount of memory used by mpls routes by changing the way
      the via addresses are stored.

      mpls: reduce memory usage of routes · cf4b24f0
      Robert Shearman 提交于
      Nexthops for MPLS routes have a via address field sized for the
      largest via address that is expected, which is 32 bytes. This means
      that in the most common case of having ipv4 via addresses, 28 bytes of
      memory more than required are used per nexthop. In the other common
      case of an ipv6 nexthop then 16 bytes more than required are
      used. With large numbers of MPLS routes this extra memory usage could
      start to become significant.
      
      To avoid allocating memory for a maximum length via address when not
      all of it is required and to allow for ease of iterating over
      nexthops, then the via addresses are changed to be stored in the same
      memory block as the route and nexthops, but in an array after the end
      of the array of nexthops. New accessors are provided to retrieve a
      pointer to the via address.
      
      To allow for O(1) access without having to store a pointer or offset
      per nh, the via address for each nexthop is sized according to the
      maximum via address for any nexthop in the route, which is stored in a
      new route field, rt_max_alen, but this is in an existing hole in
      struct mpls_route so it doesn't increase the size of the
      structure. Each via address is ensured to be aligned to VIA_ALEN_ALIGN
      to account for architectures that don't allow unaligned accesses.
