      ====================
      pull-request: bpf 2018-05-14
      
      The following pull-request contains BPF updates for your *net* tree.
      
      The main changes are:
      
      1) Fix nfp to allow zero-length BPF capabilities, meaning the nfp
         capability parsing loop will otherwise exit early if the last
         capability is zero length and therefore driver will fail to probe
         with an error such as:
      
           nfp: BPF capabilities left after parsing, parsed:92 total length:100
           nfp: invalid BPF capabilities at offset:92
      
         Fix from Jakub.
      
      2) libbpf's bpf_object__open() may return IS_ERR_OR_NULL() and not
         just an error. Fix libbpf's bpf_prog_load_xattr() to handle that
         case as well, also from Jakub.

      Rebooting while qedr is loaded with a VLAN interface present

      3c59x: convert to generic DMA API · 55c82617
      Christoph Hellwig 提交于
      This driver supports EISA devices in addition to PCI devices, and relied
      on the legacy behavior of the pci_dma* shims to pass on a NULL pointer
      to the DMA API, and the DMA API being able to handle that.  When the
      NULL forwarding broke the EISA support got broken.  Fix this by converting
      to the DMA API instead of the legacy PCI shims.

      packet: in packet_snd start writing at link layer allocation · b84bbaf7
      Willem de Bruijn 提交于
      Packet sockets allow construction of packets shorter than
      dev->hard_header_len to accommodate protocols with variable length
      link layer headers. These packets are padded to dev->hard_header_len,
      because some device drivers interpret that as a minimum packet size.
      
      packet_snd reserves dev->hard_header_len bytes on allocation.
      SOCK_DGRAM sockets call skb_push in dev_hard_header() to ensure that
      link layer headers are stored in the reserved range. SOCK_RAW sockets
      do the same in tpacket_snd, but not in packet_snd.
      
      Syzbot was able to send a zero byte packet to a device with massive
      116B link layer header, causing padding to cross over into skb_shinfo.
      Fix this by writing from the start of the llheader reserved range also
      in the case of packet_snd/SOCK_RAW.
      
      Update skb_set_network_header to the new offset. This also corrects
      it for SOCK_DGRAM, where it incorrectly double counted reserve due to
      the skb_push in dev_hard_header.
      
      Fixes: 9ed988cd ("packet: validate variable length ll headers")

      net sched actions: fix refcnt leak in skbmod · a52956df
      Roman Mashak 提交于
      When application fails to pass flags in netlink TLV when replacing
      existing skbmod action, the kernel will leak refcnt:
      
      $ tc actions get action skbmod index 1
      total acts 0
      
              action order 0: skbmod pipe set smac 00:11:22:33:44:55
               index 1 ref 1 bind 0
      
      For example, at this point a buggy application replaces the action with
      index 1 with new smac 00:aa:22:33:44:55, it fails because of zero flags,
      however refcnt gets bumped:
      
      $ tc actions get actions skbmod index 1
      total acts 0
      
              action order 0: skbmod pipe set smac 00:11:22:33:44:55
               index 1 ref 2 bind 0

      The caller calls action's ->init() and passes pointer to "struct tc_action *a",
      which later may be initialized to point at the existing action, otherwise
      "struct tc_action *a" is still invalid, and therefore dereferencing it is an
      error as happens in tcf_idr_release, where refcnt is decremented.
      
      So in case of missing flags tcf_idr_release must be called only for
      existing actions.
