"It's mostly small bugfixes and cleanups, mostly around x86 nested
virtualization. One important change, not related to nested
virtualization, is that the ability for the guest kernel to trap
CPUID instructions (in Linux that's the ARCH_SET_CPUID arch_prctl) is
now masked by default. This is because the feature is detected
through an MSR; a very bad idea that Intel seems to like more and
more. Some applications choke if the other fields of that MSR are
not initialized as on real hardware, hence we have to disable the
whole MSR by default, as was the case before Linux 4.12."

A so-called "MC-aware" mode has recently been enabled in mlxsw. In
MC-aware mode, BUM traffic is handled in a special way so that when a
switch is flooded with BUM, UC performance isn't unduly impacted.
Without enablement of this mode, a stream of BUM traffic can cause
sustained UC throughput drop in excess of 99 %.
Add a test for this behavior. Compare how much UC throughput degrades as
a stream of broadcast frames floods the switch. A minimal degradation is
tolerated to cover for glitches in traffic injection performance.

Some selftests need to tweak MTU of an interface, and naturally should
at teardown restore the MTU back to the original value. Add two
functions to facilitate this MTU handling: mtu_set() to change MTU
value, and mtu_reset() to change it back to what it was before.

There are cases where the test is not expecting to have the transaction
aborted, but, the test process might have been rescheduled, either in the
OS level or by KVM (if it is running on a KVM guest machine). The process
reschedule will cause a treclaim/recheckpoint which will cause the
transaction to doom, aborting the transaction as soon as the process is
rescheduled back to the CPU. This might cause the test to fail, but this is
not a failure in essence.
If that is the case, TEXASR[FC] is indicated with either
TM_CAUSE_RESCHEDULE or TM_CAUSE_KVM_RESCHEDULE for KVM interruptions.
In this scenario, ignore these two failures and avoid the whole test to
return failure.

A number of tls selftests rely upon recv() to return an exact number of
data bytes. When tls record crypto is done using an async accelerator,
it is possible that recv() returns lesser than expected number bytes.
This leads to failure of many test cases. To fix it, MSG_WAITALL has
been used in flags passed to recv() syscall.

In kTLS MSG_PEEK behavior is currently failing, strace example:
[pid 2430] socket(AF_INET, SOCK_STREAM, IPPROTO_IP) = 3
[pid 2430] socket(AF_INET, SOCK_STREAM, IPPROTO_IP) = 4
[pid 2430] bind(4, {sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("0.0.0.0")}, 16) = 0

[pid 2430] recvfrom(5, "test_read_peektest_read_peektest"..., 64, MSG_PEEK, NULL, NULL) = 64
As can be seen from strace, there are two TLS records sent,
i) 'test_read_peek' and ii) '_mult_recs\0' where we end up
peeking 'test_read_peektest_read_peektest'. This is clearly
wrong, and what happens is that given peek cannot call into
tls_sw_advance_skb() to unpause strparser and proceed with
the next skb, we end up looping over the current one, copying
the 'test_read_peek' over and over into the user provided
buffer.
Here, we can only peek into the currently held skb (current,
full TLS record) as otherwise we would end up having to hold
all the original skb(s) (depending on the peek depth) in a
separate queue when unpausing strparser to process next
records, minimally intrusive is to return only up to the
current record's size (which likely was what c46234ebb4d1
("tls: RX path for ktls") originally intended as well). Thus,
after patch we properly peek the first record:

Adds a test that sends different types of packets over multiple
tunnels and verifies that valid packets are dissected correctly. To do
so, a tc-flower rule is added to drop packets on UDP src port 9, and
packets are sent from ports 8, 9, and 10. Only the packets on port 9
should be dropped. Because tc-flower relies on the flow dissector to
match flows, correct classification demonstrates correct dissection.
Also add support logic to load the BPF program and to inject the test
packets.

====================
pull-request: bpf-next 2018-09-01
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add AF_XDP zero-copy support for i40e driver (!), from Björn and Magnus.
2) BPF verifier improvements by giving each register its own liveness
chain which allows to simplify and getting rid of skip_callee() logic,
from Edward.
3) Add bpf fs pretty print support for percpu arraymap, percpu hashmap
and percpu lru hashmap. Also add generic percpu formatted print on
bpftool so the same can be dumped there, from Yonghong.
4) Add bpf_{set,get}sockopt() helper support for TCP_SAVE_SYN and
TCP_SAVED_SYN options to allow reflection of tos/tclass from received
SYN packet, from Nikita.
5) Misc improvements to the BPF sockmap test cases in terms of cgroup v2
interaction and removal of incorrect shutdown() calls, from John.
6) Few cleanups in xdp_umem_assign_dev() and xdpsock samples, from Prashant.

Now that SRCU permits call_srcu() to be invoked at early boot, this
commit ensures that the rcutorture scripting tests early boot call_srcu().

Now that the RCU-bh and RCU-sched update-side functions are simple
wrappers around their RCU counterparts, there isn't a whole lot of
point in testing them. This commit therefore removes the self-test
capability and removes the corresponding kernel-boot parameters.
It also updates the various rcutorture .boot files to remove the
kernel boot parameters that call for testing RCU-bh and RCU-sched.

Only the police action allows us to specify an arbitrary numeric value
for the control action. This change introduces an explicit test case
for the above feature and then leverage it for testing the kernel behavior
for invalid control actions (reject).

This test creates a raw IPv4 socket, fragments a largish UDP
datagram and sends the fragments out of order.
Then repeats in a loop with different message and fragment lengths.
Then does the same with overlapping fragments (with overlapping
fragments the expectation is that the recv times out).
Tested:
root@<host># time ./ip_defrag.sh
ipv4 defrag
PASS
ipv4 defrag with overlaps
PASS
real 1m7.679s
user 0m0.628s
sys 0m2.242s
A similar test for IPv6 is to follow.

Now that there is only one RCU flavor to rule them all, the TREE06
and TREE08 test scenarios are redundant. This commit therefore removes
them. Later changes will rebalance and renumber the tests.

The old approach placed all the build products into the b* directories,
which meant that some of these build products needed to be copied to
the proper directory in the res hierarchy. The new approach leaves
things like .config and the .o files in the b1 directory, but directs
build output and diagnostics directly to the proper directory in the
res hierarchy. Unfortunately, one of the copies was still carried out,
which could (and sometimes did) overwrite the build output and diagnostics
with obsolete output remaining in the b1 directory.
This commit therefore removes the offending "cp" command.

Currently, we do a shutdown(sk, SHUT_RDWR) on both peer sockets and
a shutdown on the sender as well. However, this is incorrect and can
occasionally cause issues if you happen to have bad timing. First
peer1 or peer2 may still be in use depending on the test and timing.
Second we really should only be closing the read side and/or write
side depending on if the test is receiving or sending.
But, really none of this is needed just remove the shutdown calls.

Commit 3c07aaef6598 ("selftests: kselftest: change KSFT_SKIP=4 instead of
KSFT_PASS") reverted commit 11867a77eb85 ("selftests: kselftest framework:
change skip exit code to 0") but missed removing the comment which that
commit added, so do that now.

'make kselftest-merge' assumes that the config files for the tests are

and not in a subdir to android.

Pull IDA updates from Matthew Wilcox:
"A better IDA API:
id = ida_alloc(ida, GFP_xxx);
ida_free(ida, id);
rather than the cumbersome ida_simple_get(), ida_simple_remove().
The new IDA API is similar to ida_simple_get() but better named. The
internal restructuring of the IDA code removes the bitmap
preallocation nonsense.
I hope the net -200 lines of code is convincing"
