      cdc_ether: flag the u-blox TOBY-L2 and SARA-U2 as wwan · fdfbad32
      Aleksander Morgado authored
      The u-blox TOBY-L2 is a LTE Cat 4 module with HSPA+ and 2G fallback.
      This module allows switching to different USB profiles with the
      'AT+UUSBCONF' command, and provides a ECM network interface when the
      'AT+UUSBCONF=2' profile is selected.
      
      The u-blox SARA-U2 is a HSPA module with 2G fallback. The default USB
      configuration includes a ECM network interface.
      
      Both these modules are controlled via AT commands through one of the
      TTYs exposed. Connecting these modules may be done just by activating
      the desired PDP context with 'AT+CGACT=1,<cid>' and then running DHCP
      on the ECM interface.

      Intel Wired LAN Driver Updates 2017-10-09
      
      This series contains updates to ixgbe and arch/Kconfig.
      
      Mark fixes a case where PHY register access is not supported and we were
      returning a PHY address, when we should have been returning -EOPNOTSUPP.
      
      Sabrina Dubroca fixes the use of a logical "and" when it should have been
      the bitwise "and" operator.
      
      Ding Tianhong reverts the commit that added the Kconfig bool option
      ARCH_WANT_RELAX_ORDER, since there is now a new flag
      PCI_DEV_FLAGS_NO_RELAXED_ORDERING that has been added to indicate that
      Relaxed Ordering Attributes should not be used for Transaction Layer
      Packets.  Then follows up with making the needed changes to ixgbe to
      use the new PCI_DEV_FLAGS_NO_RELAXED_ORDERING flag.
      
      John Fastabend fixes an issue in the ring accounting when the transmit
      ring parameters are changed via ethtool when an XDP program is attached.

      udp: fix bcast packet reception · 996b44fc
      Paolo Abeni authored
      The commit bc044e8d ("udp: perform source validation for
      mcast early demux") does not take into account that broadcast packets
      lands in the same code path and they need different checks for the
      source address - notably, zero source address are valid for bcast
      and invalid for mcast.
      
      As a result, 2nd and later broadcast packets with 0 source address
      landing to the same socket are dropped. This breaks dhcp servers.
      
      Since we don't have stringent performance requirements for ingress
      broadcast traffic, fix it by disabling UDP early demux such traffic.

      netlink: do not set cb_running if dump's start() errs · 41c87425
      Jason A. Donenfeld authored
      It turns out that multiple places can call netlink_dump(), which means
      it's still possible to dereference partially initialized values in
      dump() that were the result of a faulty returned start().
      
      This fixes the issue by calling start() _before_ setting cb_running to
      true, so that there's no chance at all of hitting the dump() function
      through any indirect paths.
      
      It also moves the call to start() to be when the mutex is held. This has
      the nice side effect of serializing invocations to start(), which is
      likely desirable anyway. It also prevents any possible other races that
      might come out of this logic.
      
      In testing this with several different pieces of tricky code to trigger
      these issues, this commit fixes all avenues that I'm aware of.

      pull-request: mac80211 2017-10-09
      
      The QCA folks found another netlink problem - we were missing validation
      of some attributes. It's not super problematic since one can only read a
      few bytes beyond the message (and that memory must exist), but here's the
      fix for it.
      
      I thought perhaps we can make nla_parse_nested() require a policy, but
      given the two-stage validation/parsing in regular netlink that won't work.

      ipv4: Fix traffic triggered IPsec connections. · 6c0e7284
      Steffen Klassert authored
      A recent patch removed the dst_free() on the allocated
      dst_entry in ipv4_blackhole_route(). The dst_free() marked the
      dst_entry as dead and added it to the gc list. I.e. it was setup
      for a one time usage. As a result we may now have a blackhole
      route cached at a socket on some IPsec scenarios. This makes the
      connection unusable.
      
      Fix this by marking the dst_entry directly at allocation time
      as 'dead', so it is used only once.

      netfilter: xt_bpf: Fix XT_BPF_MODE_FD_PINNED mode of 'xt_bpf_info_v1' · 98589a09
      Shmulik Ladkani authored
      Commit 2c16d603 ("netfilter: xt_bpf: support ebpf") introduced
      support for attaching an eBPF object by an fd, with the
      'bpf_mt_check_v1' ABI expecting the '.fd' to be specified upon each
      IPT_SO_SET_REPLACE call.
      
      However this breaks subsequent iptables calls:
      
       # iptables -A INPUT -m bpf --object-pinned /sys/fs/bpf/xxx -j ACCEPT
       # iptables -A INPUT -s 5.6.7.8 -j ACCEPT
       iptables: Invalid argument. Run `dmesg' for more information.
      
      That's because iptables works by loading existing rules using
      IPT_SO_GET_ENTRIES to userspace, then issuing IPT_SO_SET_REPLACE with
      the replacement set.
      
      However, the loaded 'xt_bpf_info_v1' has an arbitrary '.fd' number
      (from the initial "iptables -m bpf" invocation) - so when 2nd invocation
      occurs, userspace passes a bogus fd number, which leads to
      'bpf_mt_check_v1' to fail.
      
      One suggested solution [1] was to hack iptables userspace, to perform a
      "entries fixup" immediatley after IPT_SO_GET_ENTRIES, by opening a new,
      process-local fd per every 'xt_bpf_info_v1' entry seen.
      
      However, in [2] both Pablo Neira Ayuso and Willem de Bruijn suggested to
      depricate the xt_bpf_info_v1 ABI dealing with pinned ebpf objects.
      
      This fix changes the XT_BPF_MODE_FD_PINNED behavior to ignore the given
      '.fd' and instead perform an in-kernel lookup for the bpf object given
      the provided '.path'.
      
      It also defines an alias for the XT_BPF_MODE_FD_PINNED mode, named
      XT_BPF_MODE_PATH_PINNED, to better reflect the fact that the user is
      expected to provide the path of the pinned object.
      
      Existing XT_BPF_MODE_FD_ELF behavior (non-pinned fd mode) is preserved.

      In function {ipv4,ipv6}_synproxy_hook we expect a normal tcp packet, but
      the real server maybe reply an icmp error packet related to the exist
      tcp conntrack, so we will access wrong tcp data.
      
      Fix it by checking for the protocol field and only process tcp traffic.

      tipc: Unclone message at secondary destination lookup · a9e2971b
      Jon Maloy authored
      When a bundling message is received, the function tipc_link_input()
      calls function tipc_msg_extract() to unbundle all inner messages of
      the bundling message before adding them to input queue.
      
      The function tipc_msg_extract() just clones all inner skb for all
      inner messagges from the bundling skb. This means that the skb
      headroom of an inner message overlaps with the data part of the
      preceding message in the bundle.
      
      If the message in question is a name addressed message, it may be
      subject to a secondary destination lookup, and eventually be sent out
      on one of the interfaces again. But, since what is perceived as headroom
      by the device driver in reality is the last bytes of the preceding
      message in the bundle, the latter will be overwritten by the MAC
      addresses of the L2 header. If the preceding message has not yet been
      consumed by the user, it will evenually be delivered with corrupted
      contents.
      
      This commit fixes this by uncloning all messages passing through the
      function tipc_msg_lookup_dest(), hence ensuring that the headroom
      is always valid when the message is passed on.

      tipc: correct initialization of skb list · 3382605f
      Jon Maloy authored
      We change the initialization of the skb transmit buffer queues
      in the functions tipc_bcast_xmit() and tipc_rcast_xmit() to also
      initialize their spinlocks. This is needed because we may, during
      error conditions, need to call skb_queue_purge() on those queues
      further down the stack.

      bpf: fix liveness marking · 8fe2d6cc
      Alexei Starovoitov authored
      while processing Rx = Ry instruction the verifier does
      regs[insn->dst_reg] = regs[insn->src_reg]
      which often clears write mark (when Ry doesn't have it)
      that was just set by check_reg_arg(Rx) prior to the assignment.
      That causes mark_reg_read() to keep marking Rx in this block as
      REG_LIVE_READ (since the logic incorrectly misses that it's
      screened by the write) and in many of its parents (until lucky
      write into the same Rx or beginning of the program).
      That causes is_state_visited() logic to miss many pruning opportunities.
      
      Furthermore mark_reg_read() logic propagates the read mark
      for BPF_REG_FP as well (though it's readonly) which causes
      harmless but unnecssary work during is_state_visited().
      Note that do_propagate_liveness() skips FP correctly,
      so do the same in mark_reg_read() as well.
      It saves 0.2 seconds for the test below

      ipv6: fix net.ipv6.conf.all.accept_dad behaviour for real · a2d3f3e3
      Matteo Croce authored
      Commit 35e015e1 ("ipv6: fix net.ipv6.conf.all interface DAD handlers")
      was intended to affect accept_dad flag handling in such a way that
      DAD operation and mode on a given interface would be selected
      according to the maximum value of conf/{all,interface}/accept_dad.
      
      However, addrconf_dad_begin() checks for particular cases in which we
      need to skip DAD, and this check was modified in the wrong way.
      
      Namely, it was modified so that, if the accept_dad flag is 0 for the
      given interface *or* for all interfaces, DAD would be skipped.
      
      We have instead to skip DAD if accept_dad is 0 for the given interface
      *and* for all interfaces.
