Add a test that tests a trigger that is initiated by a kernel event

Add a couple of tests that test the trace_marker histogram triggers.
One does a straight histogram test, the other will create a synthetic event
and test the latency between two different writes (using filters to
differentiate between them).

The reset_trigger() function breaks up the command by a space ' '. This is
useful to ignore the '[active]' word for triggers when removing them. But if
the trigger has a filter (ie. "if prio < 10") then the filter needs to be
attached to the line that is written into the trigger file to remove it. But
the truncation removes the filter and the triggers are not cleared properly.
Before, reset_trigger() did this:
# echo 'hist:keys=common_pid if prev_prio < 10' > events/sched/sched_switch/trigger
# echo 'hist:keys=common_pid if next_prio < 10' >> events/sched/sched_switch/trigger
# cat events/sched/sched_switch/trigger
hist:keys=common_pid:vals=hitcount:sort=hitcount:size=2048 if prev_prio < 10 [active]
hist:keys=common_pid:vals=hitcount:sort=hitcount:size=2048 if next_prio < 10 [active]
reset_trigger() {
echo '!hist:keys=common_pid:vals=hitcount:sort=hitcount:size=2048' >> events/sched/sched_switch/trigger
}
# cat events/sched/sched_switch/trigger
hist:keys=common_pid:vals=hitcount:sort=hitcount:size=2048 if prev_prio < 10 [active]
hist:keys=common_pid:vals=hitcount:sort=hitcount:size=2048 if next_prio < 10 [active]
After, where it includes the filter:
reset_trigger() {
echo '!hist:keys=common_pid:vals=hitcount:sort=hitcount:size=2048 if prev_prio < 10' >> events/sched/sched_switch/trigger
}
# cat events/sched/sched_switch/trigger
hist:keys=common_pid:vals=hitcount:sort=hitcount:size=2048 if next_prio < 10 [active]

The trigger code is picky in how it can be disabled as there may be
dependencies between different events and synthetic events. Change the order
on how triggers are reset.
1) Reset triggers of all synthetic events first
2) Remove triggers with actions attached to them
3) Remove all other triggers
If this order isn't followed, then some triggers will not be reset, and an
error may happen because a trigger is busy.

test_sock_addr was not easy to extend since it was focused on sys_bind
and sys_connect quite a bit.
Reorganized it so that it'll be easier to cover new test-cases for
`BPF_PROG_TYPE_CGROUP_SOCK_ADDR`:
- decouple test-cases so that only one BPF prog is tested at a time;
- check programmatically that local IP:port for sys_bind, source IP and
destination IP:port for sys_connect are rewritten property by tested
BPF programs.
The output of new version:

pull-request: bpf 2018-05-24
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix a bug in the original fix to prevent out of bounds speculation when
multiple tail call maps from different branches or calls end up at the
same tail call helper invocation, from Daniel.
2) Two selftest fixes, one in reuseport_bpf_numa where test is skipped in
case of missing numa support and another one to update kernel config to
properly support xdp_meta.sh test, from Anders.
...
Would be great if you have a chance to merge net into net-next after that.
The verifier fix would be needed later as a dependency in bpf-next for
upcomig work there. When you do the merge there's a trivial conflict on
BPF side with 849fa50662fb ("bpf/verifier: refine retval R0 state for
bpf_get_stack helper"): Resolution is to keep both functions, the
do_refine_retval_range() and record_func_map().

Add a new test for the seg6local End.BPF action. The following helpers
are also tested:
- bpf_lwt_push_encap within the LWT BPF IN hook
- bpf_lwt_seg6_action
- bpf_lwt_seg6_adjust_srh
- bpf_lwt_seg6_store_bytes
A chain of End.BPF actions is built. The SRH is injected through a LWT
BPF IN hook before entering this chain. Each End.BPF action validates
the previous one, otherwise the packet is dropped. The test succeeds
if the last node in the chain receives the packet and the UDP datagram
contained can be retrieved from userspace.

Recent discussions around uevent filtering (cf. net-next commit [1], [2],
and [3] and discussions in [4], [5], and [6]) have shown that the semantics
around uevent filtering where not well understood.
Now that we have settled - at least for the moment - how uevent filtering
should look like let's add some selftests to ensure we don't regress
anything in the future.
Note, the semantics of uevent filtering are described in detail in my
commit message to [2] so I won't repeat them here.

Selftests fail to build on several distros/architectures because of
missing headers files.
On a Ubuntu/x86_64 some missing headers are:
asm/byteorder.h, asm/socket.h, asm/sockios.h
On a Debian/arm32 build already fails at sys/cdefs.h
In both cases, these already exist in /usr/include/<arch-specific-dir>,
but Clang does not include these when using '-target bpf' flag,
since it is no longer compiling against the host architecture.
The solution is to:
- run Clang without '-target bpf' and extract the include chain for the
current system
- add these to the bpf build with '-idirafter'
The choice of -idirafter is to catch this error without injecting
unexpected include behavior: if an arch-specific tree is built
for bpf in the future, this will be correctly found by Clang.

specific tests to run and verbose mode rather than relying on environment
variables.

S390 bpf_jit.S is removed in net-next and had changes in 'net',
since that code isn't used any more take the removal.
TLS data structures split the TX and RX components in 'net-next',
put the new struct members from the bug fix in 'net' into the RX
part.
The 'net-next' tree had some reworking of how the ERSPAN code works in
the GRE tunneling code, overlapping with a one-line headroom
calculation fix in 'net'.
Overlapping changes in __sock_map_ctx_update_elem(), keep the bits
that read the prog members via READ_ONCE() into local variables
before using them.

Merge speculative store buffer bypass fixes from Thomas Gleixner:
- rework of the SPEC_CTRL MSR management to accomodate the new fancy
SSBD (Speculative Store Bypass Disable) bit handling.
- the CPU bug and sysfs infrastructure for the exciting new Speculative
Store Bypass 'feature'.
- support for disabling SSB via LS_CFG MSR on AMD CPUs including
Hyperthread synchronization on ZEN.
- PRCTL support for dynamic runtime control of SSB
- SECCOMP integration to automatically disable SSB for sandboxed
processes with a filter flag for opt-out.
- KVM integration to allow guests fiddling with SSBD including the new
software MSR VIRT_SPEC_CTRL to handle the LS_CFG based oddities on
AMD.
- BPF protection against SSB
.. this is just the core and x86 side, other architecture support will
come separately.

Pull x86 fixes from Thomas Gleixner:
"An unfortunately larger set of fixes, but a large portion is
selftests:
- Fix the missing clusterid initializaiton for x2apic cluster
management which caused boot failures due to IPIs being sent to the
wrong cluster
- Drop TX_COMPAT when a 64bit executable is exec()'ed from a compat
task
- Wrap access to __supported_pte_mask in __startup_64() where clang
compile fails due to a non PC relative access being generated.
- Two fixes for 5 level paging fallout in the decompressor:
- Handle GOT correctly for paging_prepare() and
cleanup_trampoline()
- Fix the page table handling in cleanup_trampoline() to avoid
page table corruption.
- Stop special casing protection key 0 as this is inconsistent with
the manpage and also inconsistent with the allocation map handling.
- Override the protection key wen moving away from PROT_EXEC to
prevent inaccessible memory.
- Fix and update the protection key selftests to address breakage and
to cover the above issue
- Add a MOV SS self test"
