Sabrina Dubroca c3b7d0bd7a macsec: fix rx_sa refcounting with decrypt callback
The decrypt callback macsec_decrypt_done needs a reference on the rx_sa
and releases it before returning, but macsec_handle_frame already
put that reference after macsec_decrypt returned NULL.

Set rx_sa to NULL when the decrypt callback runs so that
macsec_handle_frame knows it must not release the reference.

This patchset fixes two problems reported by Nikolay Aleksandrov. The first
problem is that the MDB offload flag might be accesed without helding the

Elad Raz 45ebcce568 bridge: mdb: Marking port-group as offloaded
There is a race-condition when updating the mdb offload flag without using
the mulicast_lock. This reverts commit 9e8430f8d6 ("bridge: mdb:
Passing the port-group pointer to br_mdb module").

This patch marks offloaded MDB entry as "offload" by changing the port-
group flags and marks it as MDB_PG_FLAGS_OFFLOAD.

When switchdev PORT_MDB succeeded and adds a multicast group, a completion
callback is been invoked "br_mdb_complete". The completion function
locks the multicast_lock and finds the right net_bridge_port_group and
marks it as offloaded.

Elad Raz 7ceb2afbd6 switchdev: Adding complete operation to deferred switchdev ops
When using switchdev deferred operation (SWITCHDEV_F_DEFER), the operation
is executed in different context and the application doesn't have any way
to get the operation real status.

Adding a completion callback fixes that. This patch adds fields to
switchdev_attr and switchdev_obj "complete_priv" field which is used by
the "complete" callback.

Application can set a complete function which will be called once the
operation executed.

Martin KaFai Lau b51e13faf7 tcp: Carry txstamp_ack in tcp_fragment_tstamp
When a tcp skb is sliced into two smaller skbs (e.g. in
tcp_fragment() and tso_fragment()),  it does not carry
the txstamp_ack bit to the newly created skb if it is needed.
The end result is a timestamping event (SCM_TSTAMP_ACK) will
be missing from the sk->sk_error_queue.

This patch carries this bit to the new skb2
in tcp_fragment_tstamp().

Pablo Neira Ayuso says:

====================
Netfilter updates for net-next

The following patchset contains Netfilter updates for your net-next
tree, mostly from Florian Westphal to sort out the lack of sufficient
validation in x_tables and connlabel preparation patches to add
nf_tables support. They are:

1) Ensure we don't go over the ruleset blob boundaries in
   mark_source_chains().

2) Validate that target jumps land on an existing xt_entry. This extra
   sanitization comes with a performance penalty when loading the ruleset.

3) Introduce xt_check_entry_offsets() and use it from {arp,ip,ip6}tables.

4) Get rid of the smallish check_entry() functions in {arp,ip,ip6}tables.

5) Make sure the minimal possible target size in x_tables.

6) Similar to #3, add xt_compat_check_entry_offsets() for compat code.

7) Check that standard target size is valid.

8) More sanitization to ensure that the target_offset field is correct.

9) Add xt_check_entry_match() to validate that matches are well-formed.

10-12) Three patch to reduce the number of parameters in
    translate_compat_table() for {arp,ip,ip6}tables by using a container
    structure.

13) No need to return value from xt_compat_match_from_user(), so make
    it void.

14) Consolidate translate_table() so it can be used by compat code too.

15) Remove obsolete check for compat code, so we keep consistent with
    what was already removed in the native layout code (back in 2007).

16) Get rid of target jump validation from mark_source_chains(),
    obsoleted by #2.

17) Introduce xt_copy_counters_from_user() to consolidate counter
    copying, and use it from {arp,ip,ip6}tables.

18,22) Get rid of unnecessary explicit inlining in ctnetlink for dump
    functions.

19) Move nf_connlabel_match() to xt_connlabel.

20) Skip event notification if connlabel did not change.

21) Update of nf_connlabels_get() to make the upcoming nft connlabel
    support easier.

23) Remove spinlock to read protocol state field in conntrack.

Here is one patch to wire up the preadv/pwritev system calls in the
 generic system call table, which is required for all architectures
 that were merged in the last few years, including arm64.
 
 Usually these get merged along with the syscall implementation
 or one of the architecture trees, but this time that did not
 happen.

Linus Torvalds 7c5047a124 IOMMU Fixes for Linux v4.6-rc4
The fixes include:
 
 	* Two patches to revert the use of default domains in the ARM
 	  SMMU driver. Enabling this caused regressions which need more
 	  thorough fixing. So the regressions are fixed for now by
 	  disabling the use of default domains.
 
 	* A fix for a v4.4 regression in the AMD IOMMU driver which
 	  broke devices behind invisible PCIe-to-PCI bridges with IOMMU
 	  enabled.

Linus Torvalds d4b0528827 sound fixes for 4.6-rc5
Again a relatively calm week without surprise: most of fixes are about
 HD-audio, including fixes for Cirrus codec regression and a race over
 regmap access.  Although both change are slightly unintuitive, the
 risk of further breakage is quite low, I hope.
 
 Other than that, all the rest are trivial.
