      Revert "net_sched: hold netns refcnt for each action" · c7e460ce
      由 Cong Wang 提交于 
      This reverts commit ceffcc5e.
If we hold that refcnt, the netns can never be destroyed until
all actions are destroyed by user, this breaks our netns design
which we expect all actions are destroyed when we destroy the
whole netns.

      net: usb: asix: fill null-ptr-deref in asix_suspend · 8f562462
      由 Andrey Konovalov 提交于 
      When asix_suspend() is called dev->driver_priv might not have been
assigned a value, so we need to check that it's not NULL.

Similar issue is present in asix_resume(), this patch fixes it as well.

      qmi_wwan: Add missing skb_reset_mac_header-call · 0de0add1
      由 Kristian Evensen 提交于 
      When we receive a packet on a QMI device in raw IP mode, we should call
skb_reset_mac_header() to ensure that skb->mac_header contains a valid
offset in the packet. While it shouldn't really matter, the packets have
no MAC header and the interface is configured as-such, it seems certain
parts of the network stack expects a "good" value in skb->mac_header.

Without the skb_reset_mac_header() call added in this patch, for example
shaping traffic (using tc) triggers the following oops on the first
received packet:

      bonding: fix slave stuck in BOND_LINK_FAIL state · 055db695
      由 Jay Vosburgh 提交于 
      The bonding miimon logic has a flaw, in that a failure of the
rtnl_trylock can cause a slave to become permanently stuck in
BOND_LINK_FAIL state.

	The sequence of events to cause this is as follows:

	1) bond_miimon_inspect finds that a slave's link is down, and so
calls bond_propose_link_state, setting slave->new_link_state to
BOND_LINK_FAIL, then sets slave->new_link to BOND_LINK_DOWN and returns
non-zero.

	2) In bond_mii_monitor, the rtnl_trylock fails, and the timer is
rescheduled.  No change is committed.

	3) bond_miimon_inspect is called again, but this time the slave
from step 1 has recovered.  slave->new_link is reset to NOCHANGE, and, as
slave->link was never changed, the switch enters the BOND_LINK_UP case,
and does nothing.  The pending BOND_LINK_FAIL state from step 1 remains
pending, as new_link_state is not reset.

	4) The state from step 3 persists until another slave changes link
state and causes bond_miimon_inspect to return non-zero.  At this point,
the BOND_LINK_FAIL state change on the slave from steps 1-3 is committed,
and the slave will remain stuck in BOND_LINK_FAIL state even though it
is actually link up.

	The remedy for this is to initialize new_link_state on each entry
to bond_miimon_inspect, as is already done with new_link.

      bonding: discard lowest hash bit for 802.3ad layer3+4 · b5f86218
      由 Hangbin Liu 提交于 
      After commit 07f4c900 ("tcp/dccp: try to not exhaust ip_local_port_range
in connect()"), we will try to use even ports for connect(). Then if an
application (seen clearly with iperf) opens multiple streams to the same
destination IP and port, each stream will be given an even source port.

So the bonding driver's simple xmit_hash_policy based on layer3+4 addressing
will always hash all these streams to the same interface. And the total
throughput will limited to a single slave.

Change the tcp code will impact the whole tcp behavior, only for bonding
usage. Paolo Abeni suggested fix this by changing the bonding code only,
which should be more reasonable, and less impact.

Fix this by discarding the lowest hash bit because it contains little entropy.
After the fix we can re-balance between slaves.

work around the problem by preventing userspace from interacting

      l2tp: don't use l2tp_tunnel_find() in l2tp_ip and l2tp_ip6 · 8f7dc9ae
      由 Guillaume Nault 提交于 
      Using l2tp_tunnel_find() in l2tp_ip_recv() is wrong for two reasons:

  * It doesn't take a reference on the returned tunnel, which makes the
    call racy wrt. concurrent tunnel deletion.

  * The lookup is only based on the tunnel identifier, so it can return
    a tunnel that doesn't match the packet's addresses or protocol.

For example, a packet sent to an L2TPv3 over IPv6 tunnel can be
delivered to an L2TPv2 over UDPv4 tunnel. This is worse than a simple
cross-talk: when delivering the packet to an L2TP over UDP tunnel, the
corresponding socket is UDP, where ->sk_backlog_rcv() is NULL. Calling
sk_receive_skb() will then crash the kernel by trying to execute this
callback.

And l2tp_tunnel_find() isn't even needed here. __l2tp_ip_bind_lookup()
properly checks the socket binding and connection settings. It was used
as a fallback mechanism for finding tunnels that didn't have their data
path registered yet. But it's not limited to this case and can be used
to replace l2tp_tunnel_find() in the general case.

Fix l2tp_ip6 in the same way.

      net: usb: asix: fill null-ptr-deref in asix_suspend · baedf68a
      由 Andrey Konovalov 提交于 
      When asix_suspend() is called dev->driver_priv might not have been
assigned a value, so we need to check that it's not NULL.

      netfilter/ipvs: clear ipvs_property flag when SKB net namespace changed · 2b5ec1a5
      由 Ye Yin 提交于 
      When run ipvs in two different network namespace at the same host, and one
ipvs transport network traffic to the other network namespace ipvs.
'ipvs_property' flag will make the second ipvs take no effect. So we should
clear 'ipvs_property' when SKB network namespace changed.

      arch/tile: Implement ->set_state_oneshot_stopped() · 777a45b4
      由 Chris Metcalf 提交于 
      set_state_oneshot_stopped() is called by the clkevt core, when the
next event is required at an expiry time of 'KTIME_MAX'. This normally
happens with NO_HZ_{IDLE|FULL} in both LOWRES/HIGHRES modes.

This patch makes the clockevent device to stop on such an event, to
avoid spurious interrupts, as explained by: commit 8fff52fd
("clockevents: Introduce CLOCK_EVT_STATE_ONESHOT_STOPPED state").

 "Some more powerpc fixes for 4.14.

  This is bigger than I like to send at rc7, but that's at least partly
  because I didn't send any fixes last week. If it wasn't for the IMC
  driver, which is new and getting heavy testing, the diffstat would
  look a bit better. I've also added ftrace on big endian to my test
  suite, so we shouldn't break that again in future.

   - A fix to the handling of misaligned paste instructions (P9 only),
     where a change to a #define has caused the check for the
     instruction to always fail.

   - The preempt handling was unbalanced in the radix THP flush (P9
     only). Though we don't generally use preempt we want to keep it
     working as much as possible.

   - Two fixes for IMC (P9 only), one when booting with restricted
     number of CPUs and one in the error handling when initialisation
     fails due to firmware etc.

   - A revert to fix function_graph on big endian machines, and then a
     rework of the reverted patch to fix kprobes blacklist handling on
     big endian machines.

      Update MIPS email addresses · fb615d61
      由 Paul Burton 提交于 
      MIPS will soon not be a part of Imagination Technologies, and as such
many @imgtec.com email addresses will no longer be valid. This patch
updates the addresses for those who:

 - Have 10 or more patches in mainline authored using an @imgtec.com
   email address, or any patches dated within the past year.

 - Are still with Imagination but leaving as part of the MIPS business
   unit, as determined from an internal email address list.

 - Haven't already updated their email address (ie. JamesH) or expressed
   a desire to be excluded (ie. Maciej).

 - Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt &
   myself.

New addresses are of the form firstname.lastname@mips.com, and all
verified against an internal email address list.  An entry is added to
.mailmap for each person such that get_maintainer.pl will report the new
addresses rather than @imgtec.com addresses which will soon be dead.

Instances of the affected addresses throughout the tree are then
mechanically replaced with the new @mips.com address.
