      NET: Support clause 45 MDIO commands at the MDIO bus level · abf35df2
      Jason Gunthorpe 提交于
      IEEE 802.3ae clause 45 specifies a somewhat modified MDIO protocol
      for use by 10GIGE phys. The main change is a 21 bit address split into
      a 5 bit device ID and a 16 bit register offset. The definition is designed
      so that normal and extended devices can run on the same MDIO bus.
      
      Extend mdio-bitbang to do the new protocol. At the MDIO bus level the
      protocol is requested by or'ing MII_ADDR_C45 into the register offset.
      
      Make phy_read/phy_write/etc pass a full 32 bit register offset.
      
      This does not attempt to make the phy layer support C45 style PHYs, just
      to provide the MDIO bus support.
      
      Tested against a Broadcom 10GE phy with ID 0x206034, and several
      Broadcom 10/100/1000 Phys in normal mode.

      runtime PM support to the e1000e driver.  Namely, make the driver
      suspend the device when the link is off and set it up for generating

      l2tp: Fix UDP socket reference count bugs in the pppol2tp driver · c3259c8a
      James Chapman 提交于
      This patch fixes UDP socket refcnt bugs in the pppol2tp driver.
      
      A bug can cause a kernel stack trace when a tunnel socket is closed.
      
      A way to reproduce the issue is to prepare the UDP socket for L2TP (by
      opening a tunnel pppol2tp socket) and then close it before any L2TP
      sessions are added to it. The sequence is
      
      Create UDP socket
      Create tunnel pppol2tp socket to prepare UDP socket for L2TP
        pppol2tp_connect: session_id=0, peer_session_id=0
      L2TP SCCRP control frame received (tunnel_id==0)
        pppol2tp_recv_core: sock_hold()
        pppol2tp_recv_core: sock_put
      L2TP ZLB control frame received (tunnel_id=nnn)
        pppol2tp_recv_core: sock_hold()
        pppol2tp_recv_core: sock_put
      Close tunnel management socket
        pppol2tp_release: session_id=0, peer_session_id=0
      Close UDP socket
        udp_lib_close: BUG
      
      The addition of sock_hold() in pppol2tp_connect() solves the problem.
      
      For data frames, two sock_put() calls were added to plug a refcnt leak
      per received data frame. The ref that is grabbed at the top of
      pppol2tp_recv_core() must always be released, but this wasn't done for
      accepted data frames or data frames discarded because of bad UDP
      checksums. This leak meant that any UDP socket that had passed L2TP
      data traffic (i.e. L2TP data frames, not just L2TP control frames)
      using pppol2tp would not be released by the kernel.

      l2tp: Fix oops in pppol2tp_xmit · 3feec909
      James Chapman 提交于
      When transmitting L2TP frames, we derive the outgoing interface's UDP
      checksum hardware assist capabilities from the tunnel dst dev. This
      can sometimes be NULL, especially when routing protocols are used and
      routing changes occur. This patch just checks for NULL dst or dev
      pointers when checking for netdev hardware assist features.
