RUN_TESTS function has grown and becoming harder to maintain. Move
the code that runs and tests for returns codes to a new function
and call it from RUN_TESTS.
A new RUN_TEST_PRINT_RESULT is created to simplify RUN_TESTS and make it
easier to add handling for other return codes as needed.

RUN_TESTS which is the common function that implements run_tests target,
treats all non-zero return codes from tests as failures. When tests are
skipped with non-zero return code, because of unmet dependencies and/or
unsupported configuration, it reports them as failed. This will lead to
too many false negatives even on the tests that couldn't be run.
RUN_TESTS is changed to test for SKIP=4 return from tests to enable the
framework for individual tests to return special SKIP code.
Tests will be changed as needed to report SKIP instead FAIL/PASS when
they get skipped.

Since commit 6610e0893b8bc ("RTC: Rework RTC code to use timerqueue for
events"), PIE are completely handled using hrtimers, without actually using
any underlying hardware RTC.
Move PIE testing out of rtctest. It still depends on the presence of an RTC
(to access the device file) but doesn't depend on it actually working.

We were picking up the wrong header should use asm/ioctls.h form the kernel

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

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.

If the radix tree underlying the IDR happens to be full and we attempt
to remove an id which is larger than any id in the IDR, we will call
__radix_tree_delete() with an uninitialised 'slot' pointer, at which
point anything could happen. This was easiest to hit with a single
entry at id 0 and attempting to remove a non-0 id, but it could have
happened with 64 entries and attempting to remove an id >= 64.
Roman said:
The syzcaller test boils down to opening /dev/kvm, creating an
eventfd, and calling a couple of KVM ioctls. None of this requires
superuser. And the result is dereferencing an uninitialized pointer
which is likely a crash. The specific path caught by syzbot is via
KVM_HYPERV_EVENTD ioctl which is new in 4.17. But I guess there are
other user-triggerable paths, so cc:stable is probably justified.
Matthew added:
We have around 250 calls to idr_remove() in the kernel today. Many of
them pass an ID which is embedded in the object they're removing, so
they're safe. Picking a few likely candidates:
drivers/firewire/core-cdev.c looks unsafe; the ID comes from an ioctl.
drivers/gpu/drm/amd/amdgpu/amdgpu_ctx.c is similar
drivers/atm/nicstar.c could be taken down by a handcrafted packet

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

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.
