Netfilter fixes for net

The following patchset contains a larger than usual batch of Netfilter
fixes for your net tree. This series contains a mixture of old bugs and
recently introduced bugs, they are:

1) Fix a crash when using nft_dynset with nft_set_rbtree, which doesn't

   Zhang.

2) Fix leak when nft_expr_clone() fails, from Liping Zhang.

3) Fix a race when inserting new elements to the set hash from the

4) Handle segmented TCP SIP packets properly, basically avoid that the

bnad_start_xmit(), as a producer of tx descriptors, has a few memory
barriers sprinkled around writes to producer_index and the device's
doorbell but they're not paired with anything in bnad_txcmpl_process(), a

Routes can specify an mtu explicitly or inherit the mtu from
the underlying device - this inheritance is implemented in
dst->ops->mtu handlers ip6_mtu() and ip6_blackhole_mtu().

Currently changing the mtu of a device adds mtu explicitly
to routes using that device.

ie.
  # ip link set dev lo mtu 65536
  # ip -6 route add local 2000::1 dev lo
  # ip -6 route get 2000::1
  local 2000::1 dev lo  table local  src ...  metric 1024  pref medium

  # ip link set dev lo mtu 65535
  # ip -6 route get 2000::1
  local 2000::1 dev lo  table local  src ...  metric 1024  mtu 65535 pref medium

  # ip link set dev lo mtu 65536
  # ip -6 route get 2000::1
  local 2000::1 dev lo  table local  src ...  metric 1024  mtu 65536 pref medium

  # ip -6 route del local 2000::1

After this patch the route entry no longer changes unless it already has an mtu.
There is no need: this inheritance is already done in ip6_mtu()

  # ip link set dev lo mtu 65536
  # ip -6 route add local 2000::1 dev lo
  # ip -6 route add local 2000::2 dev lo mtu 2000
  # ip -6 route get 2000::1; ip -6 route get 2000::2
  local 2000::1 dev lo  table local  src ...  metric 1024  pref medium
  local 2000::2 dev lo  table local  src ...  metric 1024  mtu 2000 pref medium

  # ip link set dev lo mtu 65535
  # ip -6 route get 2000::1; ip -6 route get 2000::2
  local 2000::1 dev lo  table local  src ...  metric 1024  pref medium
  local 2000::2 dev lo  table local  src ...  metric 1024  mtu 2000 pref medium

  # ip link set dev lo mtu 1501
  # ip -6 route get 2000::1; ip -6 route get 2000::2
  local 2000::1 dev lo  table local  src ...  metric 1024  pref medium
  local 2000::2 dev lo  table local  src ...  metric 1024  mtu 1501 pref medium

  # ip link set dev lo mtu 65536
  # ip -6 route get 2000::1; ip -6 route get 2000::2
  local 2000::1 dev lo  table local  src ...  metric 1024  pref medium
  local 2000::2 dev lo  table local  src ...  metric 1024  mtu 65536 pref medium

  # ip -6 route del local 2000::1
  # ip -6 route del local 2000::2

This is desirable because changing device mtu and then resetting it
to the previous value shouldn't change the user visible routing table.

Do not send the next message in sendmmsg for partial sendmsg
invocations.

sendmmsg assumes that it can continue sending the next message
when the return value of the individual sendmsg invocations
is positive. It results in corrupting the data for TCP,
SCTP, and UNIX streams.

For example, sendmmsg([["abcd"], ["efgh"]]) can result in a stream
of "aefgh" if the first sendmsg invocation sends only the first
byte while the second sendmsg goes through.

Datagram sockets either send the entire datagram or fail, so

Nicolas Dichtel says:
  After commit b87a2f91 ("netfilter: conntrack: add gc worker to
  remove timed-out entries"), netlink conntrack deletion events may be
  sent with a huge delay.

Nicolas further points at this line:

  goal = min(nf_conntrack_htable_size / GC_MAX_BUCKETS_DIV, GC_MAX_BUCKETS);

and indeed, this isn't optimal at all.  Rationale here was to ensure that
we don't block other work items for too long, even if
nf_conntrack_htable_size is huge.  But in order to have some guarantee
about maximum time period where a scan of the full conntrack table
completes we should always use a fixed slice size, so that once every
N scans the full table has been examined at least once.

We also need to balance this vs. the case where the system is either idle
(i.e., conntrack table (almost) empty) or very busy (i.e. eviction happens
from packet path).

So, after some discussion with Nicolas:

1. want hard guarantee that we scan entire table at least once every X s
-> need to scan fraction of table (get rid of upper bound)

2. don't want to eat cycles on idle or very busy system
-> increase interval if we did not evict any entries

3. don't want to block other worker items for too long
-> make fraction really small, and prefer small scan interval instead

4. Want reasonable short time where we detect timed-out entry when
system went idle after a burst of traffic, while not doing scans
all the time.
-> Store next gc scan in worker, increasing delays when no eviction
happened and shrinking delay when we see timed out entries.

The old gc interval is turned into a max number, scans can now happen
every jiffy if stale entries are present.

Longest possible time period until an entry is evicted is now 2 minutes
in worst case (entry expires right after it was deemed 'not expired').

The (percpu) untracked conntrack entries can end up with nonzero connmarks.

The 'untracked' conntrack objects are merely a way to distinguish INVALID
(i.e. protocol connection tracker says payload doesn't meet some
requirements or packet was never seen by the connection tracking code)
from packets that are intentionally not tracked (some icmpv6 types such as
neigh solicitation, or by using 'iptables -j CT --notrack' option).

Untracked conntrack objects are implementation detail, we might as well use
invalid magic address instead to tell INVALID and UNTRACKED apart.

The display of /proc/net/route has had a couple issues due to the fact that
when I originally rewrote most of fib_trie I made it so that the iterator
was tracking the next value to use instead of the current.

In addition it had an off by 1 error where I was tracking the first piece
of data as position 0, even though in reality that belonged to the
SEQ_START_TOKEN.

This patch updates the code so the iterator tracks the last reported
position and key instead of the next expected position and key.  In
addition it shifts things so that all of the leaves start at 1 instead of
trying to report leaves starting with offset 0 as being valid.  With these
two issues addressed this should resolve any off by one errors that were
present in the display of /proc/net/route.

map, then problem is that once a hash table extra element has been
linked into the hash-table, and the hash table is destroyed due to
refcount dropping to zero, then htab_map_free() -> delete_all_elements()
will walk the whole hash table and drop all elements via htab_elem_free().
The problem is that the element from the extra reserve is first fed
to the wrong backend allocator and eventually freed twice.

sctp_wait_for_connect() currently already holds the asoc to keep it
alive during the sleep, in case another thread release it. But Andrey
Konovalov and Dmitry Vyukov reported an use-after-free in such
situation.

Problem is that __sctp_connect() doesn't get a ref on the asoc and will
do a read on the asoc after calling sctp_wait_for_connect(), but by then
another thread may have closed it and the _put on sctp_wait_for_connect
will actually release it, causing the use-after-free.

Fix is, instead of doing the read after waiting for the connect, do it
before so, and avoid this issue as the socket is still locked by then.
There should be no issue on returning the asoc id in case of failure as
the application shouldn't trust on that number in such situations
anyway.

This issue doesn't exist in sctp_sendmsg() path.

Make sure to drop the references taken by of_get_child_by_name() and
bus_find_device() before returning from cpsw_phy_sel().

Note that holding a reference to the cpsw-phy-sel device does not
prevent the devres-managed private data from going away.

Make sure to drop the reference taken by bus_find_device_by_name()
before returning from phy_connect() and phy_attach().

Note that both function still take a reference to the phy device
through phy_attach_direct().

Mellanox 100G mlx5 fixes 2016-11-04

This series contains six hot fixes of the mlx5 core and mlx5e driver.

Huy fixed an invalid pointer dereference on initialization flow for when
the selected mlx5 load profile is out of range.

Or provided three eswitch offloads related fixes
 - Prevent changing NS of a VF representor.
 - Handle matching on vlan priority for offloaded TC rules
 - Set the actions for offloaded rules properly

On my part I here addressed the error flow related issues in
mlx5e_open_channel reported by Jesper just this week.

When prof_sel is invalid, mlx5_core_warn is called but the
mlx5_core_dev is not initialized yet. Solution is moving the prof_sel code
after dev->pdev assignment

As for the current generation of the mlx5 HW (CX4/CX4-Lx) per flow vlan
push/pop actions are emulated, we must not program them to the firmware.

We ignored the vlan priority in offloaded TC rules matching part,
fix that.
