'Commit 3c8b3efc ("vmxnet3: allow variable length transmit data ring

However, while copying data to the data ring, vmxnet3_copy_hdr continues
to carry the old code that assumes fixed buffer size of 128. This patch
fixes it by adding correct offset based on the actual data ring buffer

When tcp_sendmsg() allocates a fresh and empty skb, it puts it at the
tail of the write queue using tcp_add_write_queue_tail()

Then it attempts to copy user data into this fresh skb.

If the copy fails, we undo the work and remove the fresh skb.

Unfortunately, this undo lacks the change done to tp->highest_sack and
we can leave a dangling pointer (to a freed skb)

Later, tcp_xmit_retransmit_queue() can dereference this pointer and
access freed memory. For regular kernels where memory is not unmapped,
this might cause SACK bugs because tcp_highest_sack_seq() is buggy,
returning garbage instead of tp->snd_nxt, but with various debug
features like CONFIG_DEBUG_PAGEALLOC, this can crash the kernel.

This bug was found by Marco Grassi thanks to syzkaller.

Driver uses netif_tx_queue_stopped() to make sure the xmit_more
indication will be honored, but that only checks for DRV_XOFF.

At the same time, it's possible that during transmission the DQL will
close the transmission queue with STACK_XOFF indication.
In re-configuration flows, when the threshold is relatively low, it's
possible that the device has no pending tranmissions, and during
tranmission the driver would miss doorbelling the HW.
Since there are no pending transmission, there will never be a Tx
completion [and thus the DQL would not remove the STACK_XOFF indication],
eventually causing the Tx queue to timeout.

While we're at it - also doorbell in case driver has to close the
transmission queue on its own [although this one is less important -
if the ring is full, we're bound to receive completion eventually,
which means the doorbell would only be postponed and not indefinetly
blocked].

Netfilter fixes for net

The following patchset contains Netfilter updates for your net tree,
they are:

1) Dump only conntrack that belong to this namespace via /proc file.
   This is some fallout from the conversion to single conntrack table
   for all netns, patch from Liping Zhang.

2) Missing MODULE_ALIAS_NF_LOGGER() for the ARP family that prevents
   module autoloading, also from Liping Zhang.

3) Report overquota event to the right netnamespace, again from Liping.

4) Fix tproxy listener sk refcount that leads to crash, from
   Eric Dumazet.

5) Fix racy refcounting on object deletion from nfnetlink and rule
   removal both for nfacct and cttimeout, from Liping Zhang.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

In general, when we want to delete a netns, cttimeout_net_exit will
be called before ipt_unregister_table, i.e. before ctnl_timeout_put.

But after call kfree_rcu in cttimeout_net_exit, we will still decrease
the timeout object's refcnt in ctnl_timeout_put, this is incorrect,
and will cause a use after free error.

It is easy to reproduce this problem:
  # while : ; do
  ip netns add xxx
  ip netns exec xxx nfct add timeout testx inet icmp timeout 200
  ip netns exec xxx iptables -t raw -p icmp -I OUTPUT -j CT --timeout testx
  ip netns del xxx
  done

  =======================================================================
  BUG kmalloc-96 (Tainted: G    B       E  ): Poison overwritten

  nfnetlink_rcv_msg+0x21a/0x230 [nfnetlink]
  [ ... ]

So only when the refcnt decreased to 0, we call kfree_rcu to free the
timeout object. And like nfnetlink_acct do, use atomic_cmpxchg to
avoid race between ctnl_timeout_try_del and ctnl_timeout_put.

Suppose that we input the following commands at first:
  # nfacct add test
  # iptables -A INPUT -m nfacct --nfacct-name test

And now "test" acct's refcnt is 2, but later when we try to delete the
"test" nfacct and the related iptables rule at the same time, race maybe
happen:
      CPU0                                    CPU1
  nfnl_acct_try_del                      nfnl_acct_put
  atomic_dec_and_test //ref=1,testfail          -
       -                                 atomic_dec_and_test //ref=0,testok
       -                                 kfree_rcu
  atomic_inc //ref=1                            -

So after the rcu grace period, nf_acct will be freed but it is still linked
in the nfnl_acct_list, and we can access it later, then oops will happen.

Convert atomic_dec_and_test and atomic_inc combinaiton to one atomic
operation atomic_cmpxchg here to fix this problem.

As pointed out by Jamal, an action could be shared by
multiple filters, so we can't use list to chain them
any more after we get rid of the original tc_action.
Instead, we could just save pointers to these actions
in tcf_exts, since they are refcount'ed, so convert
the list to an array of pointers.

The "ugly" part is the action API still accepts list
as a parameter, I just introduce a helper function to
convert the array of pointers to a list, instead of
relying on the C99 feature to iterate the array.
