commit 3122257c02 upstream.
In emulated environments, the bridge ports enslaved to br1 get a carrier
before changing br1's PVID. This means that by the time the PVID is
changed, br1 is already operational and configured with an IPv6
link-local address.
When the test is run with netdevs registered by mlxsw, changing the PVID
is vetoed, as changing the VID associated with an existing L3 interface
is forbidden. This restriction is similar to the 8021q driver's
restriction of changing the VID of an existing interface.
Fix this by taking br1 down and bringing it back up when it is fully
configured.
With this fix, the test reliably passes on top of both the SW and HW
data paths (emulated or not).

commit 2bfed7d2ff upstream.
Since commit 92d25637a3 ("kselftest: signal all child processes"), tests
are executed in background process groups. This means that trying to read
from stdin now throws SIGTTIN when stdin is a TTY, which breaks some
seccomp selftests that try to use read(0, NULL, 0) as a dummy syscall.
The simplest way to fix that is probably to just use -1 instead of 0 as
the dummy read()'s FD.

[ Upstream commit 044011fdf1 ]
The test verifies that packets are correctly flooded by the bridge and
the VXLAN device by matching on the encapsulated packets at the other
end. However, if packets other than those generated by the test also
ingress the bridge (e.g., MLD packets), they will be flooded as well and
interfere with the expected count.
Make the test more robust by making sure that only the packets generated
by the test can ingress the bridge. Drop all the rest using tc filters
on the egress of 'br0' and 'h1'.
In the software data path, the problem can be solved by matching on the
inner destination MAC or dropping unwanted packets at the egress of the
VXLAN device, but this is not currently supported by mlxsw.

[ Upstream commit b50d3b46f8 ]
The purpose of the last test case is to test VXLAN encapsulation and
decapsulation when the underlay lookup takes place in a non-default VRF.
This is achieved by enslaving the physical device of the tunnel to a
VRF.
The binding of the VXLAN UDP socket to the VRF happens when the VXLAN
device itself is opened, not when its physical device is opened. This
was also mentioned in the cited commit ("tests that moving the underlay
from a VRF to another works when down/up the VXLAN interface"), but the
test did something else.
Fix it by reopening the VXLAN device instead of its physical device.
Before:
# ./test_vxlan_under_vrf.sh
Checking HV connectivity [ OK ]
Check VM connectivity through VXLAN (underlay in the default VRF) [ OK ]
Check VM connectivity through VXLAN (underlay in a VRF) [FAIL]

[ Upstream commit d23a872032 ]
In test_lwt_ip_encap, the ingress IPv6 encap test failed from time to
time. The failure occured when an IPv4 ping through the IPv6 GRE
encapsulation did not receive a reply within the timeout. The IPv4 ping
and the IPv6 ping in the test used different timeouts (1 sec for IPv4
and 6 sec for IPv6), probably taking into account that IPv6 might need
longer to successfully complete. However, when IPv4 pings (with the
short timeout) are encapsulated into the IPv6 tunnel, the delays of IPv6
apply.
The actual reason for the long delays with IPv6 was that the IPv6
neighbor discovery sometimes did not complete in time. This was caused
by the outgoing interface only having a tentative link local address,
i.e., not having completed DAD for that lladdr. The ND was successfully
retried after 1 sec but that was too late for the ping timeout.
The IPv6 addresses for the test were already added with nodad. However,
for the lladdrs, DAD was still performed. We now disable DAD in the test
netns completely and just assume that the two lladdrs on each veth pair
do not collide. This removes all the delays for IPv6 traffic in the
test.
Without the delays, we can now also reduce the delay of the IPv6 ping to
1 sec. This makes the whole test complete faster because we don't need
to wait for the excessive timeout for each IPv6 ping that is supposed
to fail.

Fix this by running cleanup() in the context of the test subshell.
Now that each test cleans the environment after completion, there's no
need for calling cleanup() again when the next test starts. So let's
drop it from the setup() function. This is okay because cleanup() is
also called when pmtu.sh starts, so even the first test starts in a
clean environment.
Also, use tcpdump's immediate mode. Otherwise it might not have time to
process buffered packets, resulting in missing packets or even empty
pcap files for short tests.
Note: PAUSE_ON_FAIL is still evaluated before cleanup(), so one can
still inspect the test environment upon failure when using -p.

[ Upstream commit 4cbd93c3c1 ]
When running the pidfd_fdinfo_test on arm64, it fails for me. After some
digging, the reason is that the child exits due to SIGBUS, because it
overflows the 1024 byte stack we've reserved for it.
To fix the issue, increase the stack size to 8192 bytes (this number is
somewhat arbitrary, and was arrived at through experimentation -- I kept
doubling until the failure no longer occurred).
Also, let's make the issue easier to debug. wait_for_pid() returns an
ambiguous value: it may return -1 in all of these cases:
1. waitpid() itself returned -1
2. waitpid() returned success, but we found !WIFEXITED(status).
3. The child process exited, but it did so with a -1 exit code.
There's no way for the caller to tell the difference. So, at least log
which occurred, so the test runner can debug things.
While debugging this, I found that we had !WIFEXITED(), because the
child exited due to a signal. This seems like a reasonably common case,
so also print out whether or not we have WIFSIGNALED(), and the
associated WTERMSIG() (if any). This lets us see the SIGBUS I'm fixing
clearly when it occurs.
Finally, I'm suspicious of allocating the child's stack on our stack.
man clone(2) suggests that the correct way to do this is with mmap(),
and in particular by setting MAP_STACK. So, switch to doing it that way
instead.

Here we group all its child processes so that kill() can signal all of
them in timeout.

[ Upstream commit f034cc1301 ]
The timeout setting for the rtc kselftest is currently 90 seconds. This
setting is used by the kselftest runner to stop running a test if it
takes longer than the assigned value.
However, two of the test cases inside rtc set alarms. These alarms are
set to the next beginning of the minute, so each of these test cases may
take up to, in the worst case, 60 seconds.
In order to allow for all test cases in rtc to run, even in the worst
case, when using the kselftest runner, the timeout value should be
increased to at least 120. Set it to 180, so there's some additional
slack.
Correct operation can be tested by running the following command right
after the start of a minute (low second count), and checking that all
test cases run:
./run_kselftest.sh -c rtc

commit 87c01d57fa upstream.
hmm_range_fault() can be used instead of get_user_pages() for devices
which allow faulting however unlike get_user_pages() it will return an
error when used on a VM_MIXEDMAP range.
To make hmm_range_fault() more closely match get_user_pages() remove
this restriction. This requires dealing with the !ARCH_HAS_PTE_SPECIAL
case in hmm_vma_handle_pte(). Rather than replicating the logic of
vm_normal_page() call it directly and do a check for the zero pfn
similar to what get_user_pages() currently does.
Also add a test to hmm selftest to verify functionality.

[ Upstream commit 3c42e95420 ]
A mis-match between reported and actual mitigation is not restricted to the
Vulnerable case. The guest might also report the mitigation as "Software
count cache flush" and the host will still mitigate with branch cache
disabled.
So, instead of skipping depending on the detected mitigation, simply skip
whenever the detected miss_percent is the expected one for a fully
mitigated system, that is, above 95%.

added a new kprobes testcase, but has a description which does not
describe what the test case is doing and is duplicating the description
of another test case.
Therefore change the test case description, so it is unique and then
allows easily to tell which test case actually passed or failed.

Test can fail either immediately when ASSERT() failed or at the
end if one or more EXPECT() was not met. The exact return code
is decided based on the number of successful ASSERT()s.
If test has no ASSERT()s, however, the return code will be 0,
as if the test did not fail. Start counting ASSERT()s from 1.

[ Upstream commit c2fcbf81c3 ]
The libbpf CI reported occasional failure in btf_skc_cls_ingress:
test_syncookie:FAIL:Unexpected syncookie states gen_cookie:80326634 recv_cookie:0
bpf prog error at line 97
"error at line 97" means the bpf prog cannot find the listening socket
when the final ack is received. It then skipped processing
the syncookie in the final ack which then led to "recv_cookie:0".
The problem is the userspace program did not do accept() and went
ahead to close(listen_fd) before the kernel (and the bpf prog) had
a chance to process the final ack.
The fix is to add accept() call so that the userspace will wait for
the kernel to finish processing the final ack first before close()-ing
everything.
