The ct_tuple v4 data structure decode / encode routines were using
the v6 IP address decode and relying on default encode. This could
cause exceptions during encode / decode depending on how a ct4
tuple would appear in a netlink message.
Caught during code review.

Kernels that don't have support for openvswitch drop reasons also
won't have the drop counter reasons, so we should skip the test
completely. It previously wasn't possible to build a test case
for this without polluting the datapath, so we introduce a mechanism
to clear all the flows from a datapath allowing us to test for
explicit drop actions, and then clear the flows to build the
original test case.

Paolo Abeni reports that on some systems the pyroute2 version isn't
new enough to run the test suite. Ensure that we support a minimum
version of 0.6 for all cases (which does include the existing ones).
The 0.6.1 version was released in May of 2021, so should be
propagated to most installations at this point.
The alternative that Paolo proposed was to only skip when the
add-flow is being run. This would be okay for most cases, except
if a future test case is added that needs to do flow dump without
an associated add (just guessing). In that case, it could also be
broken and we would need additional skip logic anyway. Just draw
a line in the sand now.

The tests rely on the IPv{4,6} FIB trace points being triggered once for
each forwarded packet. If receive processing is deferred to the
ksoftirqd task these invocations will not be counted and the tests will
fail. Fix by specifying the '-a' flag to avoid perf from filtering on
the mausezahn task.

The test relies on the fib:fib_table_lookup trace point being triggered

- fixes for Hyper-V VTL code (Saurabh Sengar and Olaf Hering)
- fix hv_kvp_daemon to support keyfile based connection profile

* tag 'hyperv-fixes-signed-20231009' of git://git.kernel.org/pub/scm/linux/kernel/git/hyperv/linux:
hv/hv_kvp_daemon:Support for keyfile based connection profile
hyperv: reduce size of ms_hyperv_info
x86/hyperv: Add common print prefix "Hyper-V" in hv_init
x86/hyperv: Remove hv_vtl_early_init initcall
x86/hyperv: Restrict get_vtl to only VTL platforms
Ifcfg config file support in NetworkManger is deprecated. This patch
provides support for the new keyfile config format for connection
profiles in NetworkManager. The patch modifies the hv_kvp_daemon code
to generate the new network configuration in keyfile
format(.ini-style format) along with a ifcfg format configuration.
The ifcfg format configuration is also retained to support easy
backward compatibility for distro vendors. These configurations are
stored in temp files which are further translated using the
hv_set_ifconfig.sh script. This script is implemented by individual
distros based on the network management commands supported.
For example, RHEL's implementation could be found here:
https://gitlab.com/redhat/centos-stream/src/hyperv-daemons/-/blob/c9s/hv_set_ifconfig.sh
Debian's implementation could be found here:
https://github.com/endlessm/linux/blob/master/debian/cloud-tools/hv_set_ifconfig
The next part of this support is to let the Distro vendors consume
these modified implementations to the new configuration format.

Martin reported that on his local dev machine the test_tc_chain_mixed() fails as
"test_tc_chain_mixed:FAIL:seen_tc5 unexpected seen_tc5: actual 1 != expected 0"
and others occasionally, too.
However, when running in a more isolated setup (qemu in particular), it works fine
for him. The reason is that there is a small race-window where seen_tc* could turn
into true for various test cases when there is background traffic, e.g. after the
asserts they often get reset. In such case when subsequent detach takes place,
unrelated background traffic could have already flipped the bool to true beforehand.
Add a small helper tc_skel_reset_all_seen() to reset all bools before we do the ping
test. At this point, everything is set up as expected and therefore no race can occur.
All tc_{opts,links} tests continue to pass after this change.

was not reset after the analysis of a timerlat activation that did not
hit the threshold.
- The IRQ handler delay is estimated from the delta of the IRQ latency
reported by timerlat, and the timestamp from IRQ handler start event.
If the delta is near-zero, the drift from the external clock and the

If the value is negative, print a zero-delay.
- IRQ handlers happening after the timerlat thread event but before
the stop tracing were being reported as IRQ that happened before the
*current* IRQ occurrence. Ignore Previous IRQ noise in this condition
because they are valid only for the *next* timerlat activation.

netfilter patches for net
First patch resolves a regression with vlan header matching, this was
broken since 6.5 release. From myself.
Second patch fixes an ancient problem with sctp connection tracking in
case INIT_ACK packets are delayed. This comes with a selftest, both
patches from Xin Long.
Patch 4 extends the existing nftables audit selftest, from
Phil Sutter.
Patch 5, also from Phil, avoids a situation where nftables
would emit an audit record twice. This was broken since 5.13 days.
Patch 6, from myself, avoids spurious insertion failure if we encounter an
overlapping but expired range during element insertion with the
'nft_set_rbtree' backend. This problem exists since 6.2.

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),

This patch adds a test case to reproduce the SCTP DATA chunk retransmission
timeout issue caused by the improper SCTP collision processing in netfilter
nf_conntrack_proto_sctp.
In this test, client sends a INIT chunk, but the INIT_ACK replied from
server is delayed until the server sends a INIT chunk to start a new
connection from its side. After the connection is complete from server
side, the delayed INIT_ACK arrives in nf_conntrack_proto_sctp.
The delayed INIT_ACK should be dropped in nf_conntrack_proto_sctp instead
of updating the vtag with the out-of-date init_tag, otherwise, the vtag
in DATA chunks later sent by client don't match the vtag in the conntrack
entry and the DATA chunks get dropped.

If no CPU list is passed, timerlat in user-space will dispatch
one thread per sysconf(_SC_NPROCESSORS_CONF). However, not all
CPU might be available, for instance, if HT is disabled.
Currently, rtla timerlat is stopping the session if an user-space
thread cannot set affinity to a CPU, or if a running user-space
thread is killed. However, this is too restrictive.
So, reduce the error to a debug message, and rtla timerlat run as
long as there is at least one user-space thread alive.

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 d4e59a536f ("selftests: Use runner.sh
for emit targets"). Although prior to that commit a548de0fe8
("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

Currently the AIA ONE_REG registers are reported by get-reg-list
as new registers for various vcpu_reg_list configs whenever Ssaia
is available on the host because Ssaia extension can only be
disabled by Smstateen extension which is not always available.
To tackle this, we should filter-out AIA ONE_REG registers only
when Ssaia can't be disabled for a VCPU.

Same set of ISA_EXT registers are not present on all host because
ISA_EXT registers are visible to the KVM user space based on the
ISA extensions available on the host. Also, disabling an ISA
extension using corresponding ISA_EXT register does not affect
the visibility of the ISA_EXT register itself.
Based on the above, we should filter-out all ISA_EXT registers.

When dynamically linking, Address Sanitizer requires its library to be the
first one to be loaded; this is apparently to ensure that every call to
malloc is intercepted. If using LD_PRELOAD, those listed libraries will
be loaded before the libraries listed in the program's ELF and will
therefore violate this requirement, leading to the below failure and
output from ASan.
commit 58e2847ad2 ("selftests: line buffer test program's stdout")
modified the kselftest runner to force line buffering by forcing the test
programs to run through `stdbuf`. It turns out that stdbuf implements
line buffering by injecting a library via LD_PRELOAD. Therefore selftests
that use ASan started failing.
Fix this by statically linking libasan in the affected test programs,
using the `-static-libasan` option. Note this is already the default for
Clang, but not got GCC.
Test output sample for failing case:
TAP version 13
1..3
# timeout set to 300
# selftests: openat2: openat2_test
# ==4052==ASan runtime does not come first in initial library list;
you should either link runtime to your application or manually preload
it with LD_PRELOAD.
not ok 1 selftests: openat2: openat2_test # exit=1
# timeout set to 300
# selftests: openat2: resolve_test
# ==4070==ASan runtime does not come first in initial library list;

The testsuite already has simply tests for HSRv0. The testuite would
have been able to notice the v1 breakage if it was there at the time.
Extend the testsuite to also cover HSRv1.

Move the code and group into functions so it will be easier to extend
the test to HSRv1 so that both versions are covered.
Move the ping/test part into do_complete_ping_test() and the interface
setup into setup_hsr_interfaces().

The timeout in the while loop is never subtracted due wrong usage of
`let' leading to an endless loop if the former condition never gets
true.
Put the statement for let in quotes so it is parsed as a single
statement.

Running commands such as
# ./perf stat -e cs -- true
Segmentation fault (core dumped)
# ./perf stat -e cpu-clock-- true
Segmentation fault (core dumped)
#
dump core. This should not happen as these events are defined
even when no hardware PMU is available.
Debugging this reveals this call chain:
perf_pmus__find_by_type(type=1)
+--> pmu_read_sysfs(core_only=false)
+--> perf_pmu__find2(dirfd=3, name=0x152a113 "software")
+--> perf_pmu__lookup(pmus=0x14f0568 <other_pmus>, dirfd=3,
lookup_name=0x152a113 "software")
+--> perf_pmu__find_events_table (pmu=0x1532130)
Now the pmu is "software" and it tries to find a proper table
generated by the pmu-event generation process for s390:
# cd pmu-events/
# ./jevents.py s390 all /root/linux/tools/perf/pmu-events/arch |\
grep -E '^const struct pmu_table_entry'
const struct pmu_table_entry pmu_events__cf_z10[] = {
const struct pmu_table_entry pmu_events__cf_z13[] = {
const struct pmu_table_entry pmu_metrics__cf_z13[] = {
const struct pmu_table_entry pmu_events__cf_z14[] = {
const struct pmu_table_entry pmu_metrics__cf_z14[] = {
const struct pmu_table_entry pmu_events__cf_z15[] = {
const struct pmu_table_entry pmu_metrics__cf_z15[] = {
const struct pmu_table_entry pmu_events__cf_z16[] = {
const struct pmu_table_entry pmu_metrics__cf_z16[] = {
const struct pmu_table_entry pmu_events__cf_z196[] = {
const struct pmu_table_entry pmu_events__cf_zec12[] = {
const struct pmu_table_entry pmu_metrics__cf_zec12[] = {
const struct pmu_table_entry pmu_events__test_soc_cpu[] = {
const struct pmu_table_entry pmu_metrics__test_soc_cpu[] = {
const struct pmu_table_entry pmu_events__test_soc_sys[] = {
#
However event "software" is not listed, as can be seen in the
generated const struct pmu_events_map pmu_events_map[].
So in function perf_pmu__find_events_table(), the variable
table is initialized to NULL, but never set to a proper
value. The function scans all generated &pmu_events_map[]
tables, but no table matches, because the tables are
s390 CPU Measurement unit specific:
i = 0;
for (;;) {
const struct pmu_events_map *map = &pmu_events_map[i++];
if (!map->arch)
break;
--> the maps are there because the build generated them
if (!strcmp_cpuid_str(map->cpuid, cpuid)) {
table = &map->event_table;
break;
}
--> Since no matching CPU string the table var remains 0x0
}
free(cpuid);
if (!pmu)
return table;
--> The pmu is "software" so it exists and no return
--> and here perf dies because table is 0x0
for (i = 0; i < table->num_pmus; i++) {
...
}
return NULL;
Fix this and do not access the table variable. Instead return 0x0
which is the same return code when the for-loop was not successful.
