[ Upstream commit 0d880dc6f032e0b541520e9926f398a77d3d433c ]
When adding/updating an object, the transaction handler emits suitable
audit log entries already, the one in nft_obj_notify() is redundant. To
fix that (and retain the audit logging from objects' 'update' callback),
Introduce an "audit log free" variant for internal use.

[ Upstream commit 203bb9d39866d3c5a8135433ce3742fe4f9d5741 ]
Add tests for sets and elements and deletion of all kinds. Also
reorder rule reset tests: By moving the bulk rule add command up, the
two 'reset rules' tests become identical.
While at it, fix for a failing bulk rule add test's error status getting
lost due to its use in a pipe. Avoid this by using a temporary file.
Headings in diff output for failing tests contain no useful data, strip
them.

This patch fixes inconsistencies in the parsing rules of the levels 1
and 2 of the kselftest_deps.sh. It was added the levels 4 and 5 to
account for a few edge cases that are present in some tests, also some

[ Upstream commit 58b33e78a31782ffe25d404d5eba9a45fe636e27 ]
In order to use run_kselftest.sh the list of tests must be emitted to
populate kselftest-list.txt.
The powerpc Makefile is written to use EMIT_TESTS. But support for
EMIT_TESTS was dropped in commit d4e59a536f50 ("selftests: Use runner.sh
for emit targets"). Although prior to that commit a548de0fe8e1
("selftests: lib.mk: add test execute bit check to EMIT_TESTS") had
already broken run_kselftest.sh for powerpc due to the executable check
using the wrong path.
It can be fixed by replacing the EMIT_TESTS definitions with actual
emit_tests rules in the powerpc Makefiles. This makes run_kselftest.sh
able to run powerpc tests:
$ cd linux
$ export ARCH=powerpc
$ export CROSS_COMPILE=powerpc64le-linux-gnu-
$ make headers
$ make -j -C tools/testing/selftests install
$ grep -c "^powerpc" tools/testing/selftests/kselftest_install/kselftest-list.txt

Make supports passing the 'jobserver' (parallel make support) to child
invocations of make when either
1. The target command uses $(MAKE) directly
2. The command starts with '+'
This context is not passed through expansions that result in $(MAKE), so
the macros used in several places fail to pass on the jobserver context.
Warnings are also raised by the child mentioning this.

[ Upstream commit c388c9920da2679f62bec48d00ca9e80e9d0a364 ]
kernel parameters allow pass two types of strings, one type is like
'noapic', another type is like 'panic=5', the first type is passed as
arguments of the init program, the second type is passed as environment
variables of the init program.
when users pass kernel parameters like this:
noapic NOLIBC_TEST=syscall
our nolibc-test program will use the test setting from argv[1] and
ignore the one from NOLIBC_TEST environment variable, and at last, it
will print the following line and ignore the whole test setting.
Ignoring unknown test name 'noapic'
reversing the parsing order does solve the above issue:
test = getenv("NOLIBC_TEST");
if (test)
test = argv[1];
but it still doesn't work with such kernel parameters (without
NOLIBC_TEST environment variable):
noapic FOO=bar
To support all of the potential kernel parameters, let's verify the test
setting from both of argv[1] and NOLIBC_TEST environment variable.

[ Upstream commit 3f3f384139ed147c71e1d770accf610133d5309b ]
When kselftest is built/installed with the 'gen_tar' target, rsync is
used for the installation step to copy files. Extra care is needed for
tests that have symlinks. Commit ae108c48b5d2 ("selftests: net: Fix
cross-tree inclusion of scripts") added '-L' (transform symlink into
referent file/dir) to rsync, to fix dangling links. However, that
broke some tests where the symlink (being a symlink) is part of the
test (e.g. exec:execveat).
Use rsync's '--copy-unsafe-links' that does right thing.

[ Upstream commit 9616cb34b08ec86642b162eae75c5a7ca8debe3c ]
Timeouts in kselftest are done using the "timeout" command with the
"--foreground" option. Without the "foreground" option, it is not
possible for a user to cancel the runner using SIGINT, because the
signal is not propagated to timeout which is running in a different
process group. The "forground" options places the timeout in the same
process group as its parent, but only sends the SIGTERM (on timeout)
signal to the forked process. Unfortunately, this does not play nice
with all kselftests, e.g. "net:fcnal-test.sh", where the child
processes will linger because timeout does not send SIGTERM to the
group.
Some users have noted these hangs [1].
Fix this by nesting the timeout with an additional timeout without the
foreground option.

commit cbc02854331edc6dc22d8b77b6e22e38ebc7dd51 upstream.
It is possible for xa_load() to observe a sibling entry pointing to
another sibling entry. An example:
Thread A: Thread B:
xa_store_range(xa, entry, 188, 191, gfp);
xa_load(xa, 191);
entry = xa_entry(xa, node, 63);
[entry is a sibling of 188]
xa_store_range(xa, entry, 184, 191, gfp);
if (xa_is_sibling(entry))
offset = xa_to_sibling(entry);
entry = xa_entry(xas->xa, node, offset);
[entry is now a sibling of 184]
It is sufficient to go around this loop until we hit a non-sibling entry.
Sibling entries always point earlier in the node, so we are guaranteed
to terminate this search.

The problem is the new offsetof() does not play nice with static asserts.

the original offsetof() definition as __builtin_offsetof().

commit 3c107f36db061603bee7564fbd6388b1f1879fd3 upstream.
There are some issues with the bpf/nat6to4.c building.
1. It use TEST_CUSTOM_PROGS, which will add the nat6to4.o to
kselftest-list file and run by common run_tests.
2. When building the test via `make -C tools/testing/selftests/
TARGETS="net"`, the nat6to4.o will be build in selftests/net/bpf/
folder. But in test udpgro_frglist.sh it refers to ../bpf/nat6to4.o.
The correct path should be ./bpf/nat6to4.o.
3. If building the test via `make -C tools/testing/selftests/ TARGETS="net"
install`. The nat6to4.o will be installed to kselftest_install/net/
folder. Then the udpgro_frglist.sh should refer to ./nat6to4.o.
To fix the confusing test path, let's just move the nat6to4.c to net folder
and build it as TEST_GEN_FILES.

[ Upstream commit be809424659c2844a2d7ab653aacca4898538023 ]
Before adding a port to bond, it need to be set down first. In the
lacpdu test the author set the port down specifically. But commit
a4abfa627c38 ("net: rtnetlink: Enslave device before bringing it up")
changed the operation order, the kernel will set the port down _after_
adding to bond. So all the ports will be down at last and the test failed.
In fact, the veth interfaces are already inactive when added. This
means there's no need to set them down again before adding to the bond.
Let's just remove the link down operation.

[ Upstream commit 855067defa36b1f9effad8c219d9a85b655cf500 ]
This test verifies whether the encapsulated packets have the correct
configured TTL. It does so by sending ICMP packets through the test
topology and mirroring them to a gretap netdevice. On a busy host
however, more than just the test ICMP packets may end up flowing
through the topology, get mirrored, and counted. This leads to
potential spurious failures as the test observes much more mirrored
packets than the sent test packets, and assumes a bug.
Fix this by tightening up the mirror action match. Change it from
matchall to a flower classifier matching on ICMP packets specifically.

The test relies on 'nc' being the netcat version from the nmap project.
While this seems to be the case on Fedora, it is not the case on Ubuntu,
resulting in failures such as [1].
Fix by explicitly using the 'ncat' utility from the nmap project and the
skip the test in case it is not installed.

commit 8743aeff5bc4dcb5b87b43765f48d5ac3ad7dd9f upstream.
A netlink dump callback can return a positive number to signal that more
information needs to be dumped or zero to signal that the dump is
complete. In the second case, the core netlink code will append the
NLMSG_DONE message to the skb in order to indicate to user space that
the dump is complete.
The nexthop bucket dump callback always returns a positive number if
nexthop buckets were filled in the provided skb, even if the dump is
complete. This means that a dump will span at least two recvmsg() calls
as long as nexthop buckets are present. In the last recvmsg() call the
dump callback will not fill in any nexthop buckets because the previous
call indicated that the dump should restart from the last dumped nexthop
ID plus one.

This behavior is both inefficient and buggy. If the last nexthop to be
dumped had the maximum ID of 0xffffffff, then the dump will restart from
0 (0xffffffff + 1) and never end:

commit 9ee37e53e7687654b487fc94e82569377272a7a8 upstream.
The test checks that filters that match on source or destination MAC
were only hit once. A host can send more than one packet with a given
source or destination MAC, resulting in failures.
Fix by relaxing the success criterion and instead check that the filters
were not hit zero times. Using tc_check_at_least_x_packets() is also an
option, but it is not available in older kernels.

Fix by switching off the timeout and setting it to 0. A similar change
was done for BPF selftests in commit 6fc5916cc256 ("selftests: bpf:

commit d72c83b1e4b4a36a38269c77a85ff52f95eb0d08 upstream.
As explained in [1], the forwarding selftests are meant to be run with
either physical loopbacks or veth pairs. The interfaces are expected to
be specified in a user-provided forwarding.config file or as command
line arguments. By default, this file is not present and the tests fail:
# make -C tools/testing/selftests TARGETS=net/forwarding run_tests
[...]
TAP version 13
1..102
# timeout set to 45
# selftests: net/forwarding: bridge_igmp.sh
# Command line is not complete. Try option "help"
# Failed to create netif
not ok 1 selftests: net/forwarding: bridge_igmp.sh # exit=1
[...]
Fix by skipping a test if interfaces are not provided either via the
configuration file or command line arguments.
# make -C tools/testing/selftests TARGETS=net/forwarding run_tests
[...]
TAP version 13
1..102
# timeout set to 45

commit cac7ea57a06016e4914848b707477fb07ee4ae1c upstream.
Currently the pthread allocation for each array item is based on the size
of a pthread_t pointer and should be the size of the pthread_t structure,
so the allocation is under-allocating the correct size. Fix this by using
the size of each element in the pthreads array.

commit c8c101ae390a3e817369e94a6f12a1ddea420702 upstream.
mptcp_join 'implicit EP' test currently fails when using ip mptcp:
$ ./mptcp_join.sh -iI
<snip>
001 implicit EP creation[fail] expected '10.0.2.2 10.0.2.2 id 1 implicit' found '10.0.2.2 id 1 rawflags 10 '
Error: too many addresses or duplicate one: -22.
ID change is prevented[fail] expected '10.0.2.2 10.0.2.2 id 1 implicit' found '10.0.2.2 id 1 rawflags 10 '
modif is allowed[fail] expected '10.0.2.2 10.0.2.2 id 1 signal' found '10.0.2.2 id 1 signal '
This happens because of two reasons:
- iproute v6.3.0 does not support the implicit flag, fixed with
iproute2-next commit 3a2535a41854 ("mptcp: add support for implicit
flag")
- pm_nl_check_endpoint wrongly expects the ip address to be repeated two
times in iproute output, and does not account for a final whitespace
in it.
This fixes the issue trimming the whitespace in the output string and
removing the double address in the expected string.

commit aaf2123a5cf46dbd97f84b6eee80269758064d93 upstream.
mptcp_join 'delete and re-add' test fails when using ip mptcp:
$ ./mptcp_join.sh -iI

002 delete and re-add before delete[ ok ]
mptcp_info subflows=1 [ ok ]
Error: argument "ADDRESS" is wrong: invalid for non-zero id address
after delete[fail] got 2:2 subflows expected 1
This happens because endpoint delete includes an ip address while id is
not 0, contrary to what is indicated in the ip mptcp man page:
"When used with the delete id operation, an IFADDR is only included when
the ID is 0."
This fixes the issue using the $addr variable in pm_nl_del_endpoint()
only when id is 0.

[ Upstream commit 3bcbc20942db5d738221cca31a928efc09827069 ]
To allow running rseq and KVM's rseq selftests as statically linked
binaries, initialize the various "trampoline" pointers to point directly
at the expect glibc symbols, and skip the dlysm() lookups if the rseq
size is non-zero, i.e. the binary is statically linked *and* the libc
registered its own rseq.
Define weak versions of the symbols so as not to break linking against
libc versions that don't support rseq in any capacity.
The KVM selftests in particular are often statically linked so that they
can be run on targets with very limited runtime environments, i.e. test
machines.

[ Upstream commit e739718444f7bf2fa3d70d101761ad83056ca628 ]
syzkaller found zero division error [0] in div_s64_rem() called from
get_cycle_time_elapsed(), where sched->cycle_time is the divisor.
We have tests in parse_taprio_schedule() so that cycle_time will never
be 0, and actually cycle_time is not 0 in get_cycle_time_elapsed().
The problem is that the types of divisor are different; cycle_time is
s64, but the argument of div_s64_rem() is s32.
syzkaller fed this input and 0x100000000 is cast to s32 to be 0.
@TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME={0xc, 0x8, 0x100000000}
We use s64 for cycle_time to cast it to ktime_t, so let's keep it and
set max for cycle_time.
While at it, we prevent overflow in setup_txtime() and add another
test in parse_taprio_schedule() to check if cycle_time overflows.
Also, we add a new tdc test case for this issue.

If 'iptables-legacy' is available, 'ip6tables-legacy' command will be
used instead of 'ip6tables'. So no need to look if 'ip6tables' is
available in this case.
