selftests: pmtu.sh: Kill nettest processes launched in subshell.
When using "run_cmd <command> &", then "$!" refers to the PID of the
subshell used to run <command>, not the command itself. Therefore
nettest_pids actually doesn't contain the list of the nettest commands
running in the background. So cleanup() can't kill them and the nettest
processes run until completion (fortunately they have a 5s timeout).
Fix this by defining a new command for running processes in the
background, for which "$!" really refers to the PID of the command run.
Also, double quote variables on the modified lines, to avoid shellcheck
warnings.

selftests: pmtu.sh: Kill tcpdump processes launched by subshell.
The cleanup() function takes care of killing processes launched by the
test functions. It relies on variables like ${tcpdump_pids} to get the
relevant PIDs. But tests are run in their own subshell, so updated
*_pids values are invisible to other shells. Therefore cleanup() never
sees any process to kill:
$ ./tools/testing/selftests/net/pmtu.sh -t pmtu_ipv4_exception
TEST: ipv4: PMTU exceptions [ OK ]
TEST: ipv4: PMTU exceptions - nexthop objects [ OK ]
$ pgrep -af tcpdump

6235 tcpdump -s 0 -i veth_B-R2 -w pmtu_ipv4_exception_veth_B-R2.pcap
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.

selftests/vm: cleanup hugetlb file after mremap test
The hugepage-mremap test will create a file in a hugetlb filesystem. In a default 'run_vmtests' run, the file will contain all the hugetlb pages. After the test, the file remains and there are no free hugetlb pages for subsequent tests. This causes those hugetlb tests to fail. Change hugepage-mremap to take the name of the hugetlb file as an argument. Unlink the file within the test, and just to be sure remove the file in the run_vmtests script.

selftests: mlxsw: resource_scale: Fix return value
The test runs several test cases and is supposed to return an error in
case at least one of them failed.
Currently, the check of the return value of each test case is in the
wrong place, which can result in the wrong return value. For example:
# TESTS='tc_police' ./resource_scale.sh
TEST: 'tc_police' [default] 968 [FAIL]
tc police offload count failed
Error: mlxsw_spectrum: Failed to allocate policer index.
We have an error talking to the kernel
Command failed /tmp/tmp.i7Oc5HwmXY:969
TEST: 'tc_police' [default] overflow 969 [ OK ]
...
TEST: 'tc_police' [ipv4_max] overflow 969 [ OK ]
$ echo $?
0
Fix this by moving the check to be done after each test case.

selftests: mlxsw: tc_police_scale: Make test more robust
The test adds tc filters and checks how many of them were offloaded by
grepping for 'in_hw'.
iproute2 commit f4cd4f127047 ("tc: add skip_hw and skip_sw to control
action offload") added offload indication to tc actions, producing the
following output:
$ tc filter show dev swp2 ingress

The current grep expression matches on both 'in_hw' and 'not_in_hw',
resulting in incorrect results.
Fix that by using JSON output instead.

Running the memfd script ./run_hugetlbfs_test.sh will often end in error as follows: memfd-hugetlb: CREATE memfd-hugetlb: BASIC memfd-hugetlb: SEAL-WRITE memfd-hugetlb: SEAL-FUTURE-WRITE memfd-hugetlb: SEAL-SHRINK fallocate(ALLOC) failed: No space left on device ./run_hugetlbfs_test.sh: line 60: 166855 Aborted (core dumped) ./memfd_test hugetlbfs opening: ./mnt/memfd fuse: DONE If no hugetlb pages have been preallocated, run_hugetlbfs_test.sh will allocate 'just enough' pages to run the test. In the SEAL-FUTURE-WRITE test the mfd_fail_write routine maps the file, but does not unmap. As a result, two hugetlb pages remain reserved for the mapping. When the fallocate call in the SEAL-SHRINK test attempts allocate all hugetlb pages, it is short by the two reserved pages. Fix by making sure to unmap in mfd_fail_write.

KVM: selftests: aarch64: Skip tests if we can't create a vgic-v3
The arch_timer and vgic_irq kselftests assume that they can create a vgic-v3, using the library function vgic_v3_setup() which aborts with a test failure if it is not possible to do so. Since vgic-v3 can only be instantiated on systems where the host has GICv3 this leads to false positives on older systems where that is not the case. Fix this by changing vgic_v3_setup() to return an error if the vgic can't be instantiated and have the callers skip if this happens. We could also exit flagging a skip in vgic_v3_setup() but this would prevent future test cases conditionally deciding which GIC to use or generally doing more complex output.

selftests: bpf: Check bpf_msg_push_data return value
bpf_msg_push_data may return a non-zero value to indicate an error. The
return value should be checked to prevent undetected errors.
To indicate an error, the BPF programs now perform a different action
than their intended one to make the userspace test program notice the
error, i.e., the programs supposed to pass/redirect drop, the program
supposed to drop passes.

selftests/seccomp: Fix seccomp failure by adding missing headers
seccomp_bpf failed on tests 47 global.user_notification_filter_empty and 48 global.user_notification_filter_empty_threaded when it's tested on updated kernel but with old kernel headers. Because old kernel headers don't have definition of macro __NR_clone3 which is required for these two tests. Since under selftests/, we can install headers once for all tests (the default INSTALL_HDR_PATH is usr/include), fix it by adding usr/include to the list of directories to be searched. Use "-isystem" to indicate it's a system directory as the real kernel headers directories are.

selftests: netfilter: disable rp_filter on router
Some distros may enable rp_filter by default. After ns1 change addr to
10.0.2.99 and set default router to 10.0.2.1, while the connected router
address is still 10.0.1.1. The router will not reply the arp request
from ns1. Fix it by setting the router's veth0 rp_filter to 0.
Before the fix:
# ./nft_fib.sh
PASS: fib expression did not cause unwanted packet drops
Netns nsrouter-HQkDORO2 fib counter doesn't match expected packet count of 1 for 1.1.1.1
table inet filter {

ip6 daddr 1c3::c01d fib saddr . iif oif missing counter packets 0 bytes 0 drop
}
}
After the fix:
# ./nft_fib.sh
PASS: fib expression did not cause unwanted packet drops
PASS: fib expression did drop packets for 1.1.1.1

selftests: mptcp: add missing join check
This function also writes the name of the test with its ID, making clear
a new test has been executed.
Without that, the ADD_ADDR results from this test was appended at the
end of the previous test causing confusions. Especially when the second
test was failing, we had:
17 signal invalid addresses syn[ ok ] - synack[ ok ] - ack[ ok ]
add[ ok ] - echo [ ok ]
add[fail] got 2 ADD_ADDR[s] expected 3
In fact, this 17th test was OK but not the 18th one.
Now we have:
17 signal invalid addresses syn[ ok ] - synack[ ok ] - ack[ ok ]
add[ ok ] - echo [ ok ]
18 signal addresses race test syn[fail] got 2 JOIN[s] syn expected 3

selftests: fixup build warnings in pidfd / clone3 tests
These are some trivial fixups, which were needed to build the tests with clang and -Werror. The following issues are fixed: - Remove various unused variables. - In child_poll_leader_exit_test, clang isn't smart enough to realize syscall(SYS_exit, 0) won't return, so it complains we never return from a non-void function. Add an extra exit(0) to appease it. - In test_pidfd_poll_leader_exit, ret may be branched on despite being uninitialized, if we have !use_waitpid. Initialize it to zero to get the right behavior in that case.

pidfd: fix test failure due to stack overflow on some arches
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.
