Changed the description of tep_add_plugin_path() API to reflect the
logic of the function. The suffix of plugin files is not hardcoded
to ".so", it depends on the custom plugin loader callback.

A single q option decodes ip from only FUP/TIP packets. Make it so that
repeating the q option (i.e. qq) decodes only PSB+, getting ip if there
is a FUP packet within PSB+ (i.e. between PSB and PSBEND).
Example:
$ perf record -e intel_pt//u grep -rI pudding drivers
[ perf record: Woken up 52 times to write data ]
[ perf record: Captured and wrote 57.870 MB perf.data ]
$ time perf script --itrace=bi | wc -l

Use the new itrace 'q' option to add support for a mode of decoding that
ignores TNT, does not walk object code, but gets the ip from FUP and TIP
packets.

$ perf record -e intel_pt//u grep -rI pudding drivers
[ perf record: Woken up 52 times to write data ]
[ perf record: Captured and wrote 57.870 MB perf.data ]

The 'q' option is for modes of decoding that are quicker because they
skip or omit decoding some aspects of trace data.
If supported, the 'q' option may be repeated to increase the effect.

Change the debug logging (when used with the --time option) to time
filter logged perf events, but allow that to be overridden by using
"d+a" instead of plain "d".
That can reduce the size of the log file.

The "d" option may be followed by flags which affect what debug messages

'-'. The flags support by Intel PT are:
-a Suppress logging of perf events
Suppressing perf events is useful for decreasing the size of the log.

The itrace "e" option may be followed by flags which affect what errors
will or will not be reported. Each flag must be preceded by either '+' or '-'.
The flags supported by Intel PT are:
-o Suppress overflow errors
-l Suppress trace data lost errors
For example, for errors but not overflow or data lost errors:
--itrace=e-o-l
Suppressing those errors can be useful for testing and debugging because
they are not due to decoding.

While walking code towards a FUP ip, the packet state is
INTEL_PT_STATE_FUP or INTEL_PT_STATE_FUP_NO_TIP. That was mishandled
resulting in the state becoming INTEL_PT_STATE_IN_SYNC prematurely. The
result was an occasional lost EXSTOP event.

misc bug fixes for the hso driver
1. Code reuse led to an unregistration of a net driver that has not been
registered
2. The kernel complains generically if kmalloc with GFP_KERNEL fails
3. A race that can lead to an URB that is in use being reused or
a use after free

This check an inherent race. It opens a race where
an error code has already been set or cleared yet
the URB has not been given back. We cannot do
such an optimization and must unlink unconditionally.

The driver tries to reuse code for disconnect in case
of a failed probe.
If resources need to be freed after an error in probe, the
netdev must not be freed because it has never been registered.
Fix it by telling the helper which path we are in.

On architectures defining _HAVE_ARCH_IPV6_CSUM, we get
csum_ipv6_magic() defined by means of arch checksum.h headers. On
other architectures, we actually need to include net/ip6_checksum.h
to be able to use it.
Without this include, building with defconfig breaks at least for
s390.

The msg_zerocopy test pins the sender and receiver threads to separate
cores to reduce variance between runs.
But it hardcodes the cores and skips core 0, so it fails on machines
with the selected cores offline, or simply fewer cores.
The test mainly gives code coverage in automated runs. The throughput
of zerocopy ('-z') and non-zerocopy runs is logged for manual
inspection.
Continue even when sched_setaffinity fails. Just log to warn anyone
interpreting the data.

The MPTCP protocol is trying to create a subflow for an
unaccepted server socket. That is allowed by the RFC, even
if subflow creation will likely fail.
Unaccepted sockets have still a NULL sk_socket field,
avoid the issue by failing earlier.

====================
selftests: rtnetlink: Fix for false-negative return values
This patchset will address the false-negative return value issue
caused by the following:
1. The return value "ret" in this script will be reset to 0 from
the beginning of each sub-test in rtnetlink.sh, therefore this
rtnetlink test will always pass if the last sub-test has passed.
2. The test result from two sub-tests in kci_test_encap() were not
being processed, thus they will not affect the final test result
of this test.

kci_test_encap() is actually composed by two different sub-tests,
kci_test_encap_vxlan() and kci_test_encap_fou()
Therefore we should check the test result of these two in
kci_test_encap() to let the script be aware of the pass / fail status.
Otherwise it will generate false-negative result like below:

Make "ret" become a local variable for all sub-tests.
Also, check the sub-test results in kci_test_rtnl() and return the
final result for this test.

Although we can detect the chip revision 100% at runtime, it is useful
to specify it in the device tree compatible string too, because
otherwise there would be no way to assess the correctness of device tree
bindings statically, without booting a board (only some switch versions
have internal RGMII delays and/or an SGMII port).
But for testing the P/Q/R/S support, what I have is a reworked board
with the SJA1105T replaced by a pin-compatible SJA1105Q, and I don't
want to keep a separate device tree blob just for this one-off board.
Since just the chip has been replaced, its RGMII delay setup is
inherently the same (meaning: delays added by the PHY on the slave
ports, and by PCB traces on the fixed-link CPU port).
For this board, I'd rather have the driver shout at me, but go ahead and
use what it found even if it doesn't match what it's been told is there.

Without ub->ifindex set for ipv6 address in tipc_udp_enable(),
ipv6_sock_mc_join() may make the wrong dev join the multicast
address in enable_mcast(). This causes that tipc links would
never be created.
So fix it by getting the right netdev and setting ub->ifindex,
as it does for ipv4 address.

It will be used by TIPC protocol. So also export it.

ovs_flow_tbl_destroy always is called from RCU callback
or error path. It is no need to check if rcu_read_lock
or lockdep_ovsl_is_held was held.
ovs_dp_cmd_fill_info always is called with ovs_mutex,
So use the rcu_dereference_ovsl instead of rcu_dereference
in ovs_flow_tbl_masks_cache_size.

This reverts commit 71130f29979c7c7956b040673e6b9d5643003176.
In commit 71130f29979c ("vxlan: fix tos value before xmit") we want to
make sure the tos value are filtered by RT_TOS() based on RFC1349.
0 1 2 3 4 5 6 7
+-----+-----+-----+-----+-----+-----+-----+-----+
| PRECEDENCE | TOS | MBZ |
+-----+-----+-----+-----+-----+-----+-----+-----+
But RFC1349 has been obsoleted by RFC2474. The new DSCP field defined like
0 1 2 3 4 5 6 7
+-----+-----+-----+-----+-----+-----+-----+-----+
| DS FIELD, DSCP | ECN FIELD |
+-----+-----+-----+-----+-----+-----+-----+-----+
So with
IPTOS_TOS_MASK 0x1E
RT_TOS(tos) ((tos)&IPTOS_TOS_MASK)
the first 3 bits DSCP info will get lost.
To take all the DSCP info in xmit, we should revert the patch and just push
all tos bits to ip_tunnel_ecn_encap(), which will handling ECN field later.

The way we define the phase (the difference between the time of the
signal's rising edge, and the closest integer multiple of the period),
it doesn't make sense to have a phase value equal or larger than 1
period.
So deny these settings coming from the user.

The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.
When memory is allocated in 'fst_add_one()', GFP_KERNEL can be used
because it is a probe function and no lock is acquired.

If the accelerated networking SRIOV VF device has lost carrier
use the synthetic network device which is available as backup
path. This is a rare case since if VF link goes down, normally
the VMBus device will also loose external connectivity as well.
But if the communication is between two VM's on the same host
the VMBus device will still work.

on the GARDENA smart Gateway, which is based on the AT91SAM9G25.
Debugging showed that the "GEM bits" in the NCFGR register are now
unconditionally accessed, which is incorrect for the !macb_is_gem()
case.
This patch adds the macb_is_gem() checks back to the code
(in macb_mac_config() & macb_mac_link_up()), so that the GEM register
bits are not accessed in this case any more.

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) Flush the cleanup xtables worker to make sure destructors
have completed, from Florian Westphal.
2) iifgroup is matching erroneously, also from Florian.
3) Add selftest for meta interface matching, from Florian Westphal.
4) Move nf_ct_offload_timeout() to header, from Roi Dayan.
5) Call nf_ct_offload_timeout() from flow_offload_add() to
make sure garbage collection does not evict offloaded flow,
from Roi Dayan.

On heavily loaded systems the GC can take time to go over all existing
conns and reset their timeout. At that time other calls like from
nf_conntrack_in() can call of nf_ct_is_expired() and see the conn as
expired. To fix this when we set the offload bit we should also reset
the timeout instead of counting on GC to finish first iteration over
all conns before the initial timeout.

simple test case, but would have caught this:
FAIL: iifgroupcount, want "packets 2", got
table inet filter {
counter iifgroupcount {
packets 0 bytes 0
}
}

iifgroup matching erroneously checks the output interface.
