      tcp: TCP Fast Open Server - record retransmits after 3WHS · 30099b2e
      Neal Cardwell authored
      When recording the number of SYNACK retransmits for servers using TCP
      Fast Open, fix the code to ensure that we copy over the retransmit
      count from the request_sock after we receive the ACK that completes
      the 3-way handshake.
      
      The story here is similar to that of SYNACK RTT
      measurements. Previously we were always doing this in
      tcp_v4_syn_recv_sock(). However, for TCP Fast Open connections
      tcp_v4_conn_req_fastopen() calls tcp_v4_syn_recv_sock() at the time we
      receive the SYN. So for TFO we must copy the final SYNACK retransmit
      count in tcp_rcv_state_process().
      
      Note that copying over the SYNACK retransmit count will give us the
      correct count since, as is mentioned in a comment in
      tcp_retransmit_timer(), before we receive an ACK for our SYN-ACK a TFO
      passive connection does not retransmit anything else (e.g., data or
      FIN segments).

      can: mscan-mpc5xxx: fix return value check in mpc512x_can_get_clock() · f61bd058
      Wei Yongjun authored
      In case of error, the function clk_get() returns ERR_PTR()
      and never returns NULL pointer. The NULL test in the error
      handling should be replaced with IS_ERR().

      ipconfig: add nameserver IPs to kernel-parameter ip= · 5e953778
      Christoph Fritz authored
      On small systems (e.g. embedded ones) IP addresses are often configured
      by bootloaders and get assigned to kernel via parameter "ip=".  If set to
      "ip=dhcp", even nameserver entries from DHCP daemons are handled. These
      entries exported in /proc/net/pnp are commonly linked by /etc/resolv.conf.
      
      To configure nameservers for networks without DHCP, this patch adds option
      <dns0-ip> and <dns1-ip> to kernel-parameter 'ip='.

      net: qmi_wwan: adding Huawei E367, ZTE MF683 and Pantech P4200 · 42d94dcb
      Bjørn Mork authored
      One of the modes of Huawei E367 has this QMI/wwan interface:
      
       I:* If#= 1 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=01 Prot=07 Driver=(none)
       E:  Ad=83(I) Atr=03(Int.) MxPS=  64 Ivl=2ms
       E:  Ad=84(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
       E:  Ad=02(O) Atr=02(Bulk) MxPS= 512 Ivl=4ms
      
      Huawei use subclass and protocol to identify vendor specific
      functions, so adding a new vendor rule for this combination.
      
      The Pantech devices UML290 (106c:3718) and P4200 (106c:3721) use
      the same subclass to identify the QMI/wwan function.  Replace the
      existing device specific UML290 entries with generic vendor matching,
      adding support for the Pantech P4200.
      
      The ZTE MF683 has 6 vendor specific interfaces, all using
      ff/ff/ff for cls/sub/prot.  Adding a match on interface #5 which
      is a QMI/wwan interface.
