d14d6b0e7d selftests/damon/_damon_sysfs: support quota goals
Patch series "selftests/damon: add DAMOS quota goal test".

Extend DAMON selftest-purpose sysfs wrapper to support DAMOS quota goal,
and implement a simple selftest for the feature using it.


This patch (of 2):

The DAMON sysfs test purpose wrapper, _damon_sysfs.py, is not supporting
quota goals.  Implement the support for testing the feature.  The test
will be implemented and added by the following commit.

selftests/harness: Handle TEST_F()'s explicit exit codes
If TEST_F() explicitly calls exit(code) with code different than 0, then
_metadata->exit_code is set to this code (e.g. KVM_ONE_VCPU_TEST()).  We
need to keep in mind that _metadata->exit_code can be KSFT_SKIP while
the process exit code is 0.

selftests/harness: Fix vfork() side effects
Setting the time namespace with CLONE_NEWTIME returns -EUSERS if the
calling thread shares memory with another thread (because of the shared
vDSO), which is the case when it is created with vfork().

Fix pidfd_setns_test by replacing test harness's vfork() call with a
clone3() call with CLONE_VFORK, and an explicit sharing of the
_metadata and self objects.

Replace _metadata->teardown_parent with a new FIXTURE_TEARDOWN_PARENT()
helper that can replace FIXTURE_TEARDOWN().  This is a cleaner approach
and it enables to selectively share the fixture data between the child
process running tests and the parent process running the fixture
teardown.  This also avoids updating several tests to not rely on the
self object's copy-on-write property (e.g. storing the returned value of
a fork() call).

selftests/harness: Share _metadata between forked processes
Unconditionally share _metadata between all forked processes, which
enables to actually catch errors which were previously ignored.

This is required for a following commit replacing vfork() with clone3()
and CLONE_VFORK (i.e. not sharing the full memory) .  It should also be
useful to share _metadata to extend expectations to test process's
forks.  For instance, this change identified a wrong expectation in
pidfd_setns_test.

Because this _metadata is used by the new XFAIL_ADD(), use a global
pointer initialized in TEST_F().  This is OK because only XFAIL_ADD()
use it, and XFAIL_ADD() already depends on TEST_F().

selftests/harness: Fix interleaved scheduling leading to race conditions
Fix a race condition when running several FIXTURE_TEARDOWN() managing
the same resource.  This fixes a race condition in the Landlock file
system tests when creating or unmounting the same directory.

Using clone3() with CLONE_VFORK guarantees that the child and grandchild
test processes are sequentially scheduled.  This is implemented with a
new clone3_vfork() helper replacing the fork() call.

This avoids triggering this error in __wait_for_test():
  Test ended in some other way [127]

d9c5f5f94c perf pmu: Count sys and cpuid JSON events separately
Sys events are eagerly loaded as each event has a compat option that may
mean the event is or isn't associated with the PMU.

These shouldn't be counted as loaded_json_events as that is used for
JSON events matching the CPUID that may or may not have been loaded. The
mismatch causes issues on ARM64 that uses sys events.

193a9e3020 perf stat: Don't display metric header for non-leader uncore events
On an Intel tigerlake laptop a metric like:

    {
        "BriefDescription": "Test",
        "MetricExpr": "imc_free_running@data_read@ + imc_free_running@data_write@",
        "MetricGroup": "Test",
        "MetricName": "Test",
        "ScaleUnit": "6.103515625e-5MiB"
    },

Will have 4 events:

  uncore_imc_free_running_0/data_read/
  uncore_imc_free_running_0/data_write/
  uncore_imc_free_running_1/data_read/
  uncore_imc_free_running_1/data_write/

If aggregration is disabled with metric-only 2 column headers are
needed:

  $ perf stat -M test --metric-only -A -a sleep 1

   Performance counter stats for 'system wide':

                    MiB  Test            MiB  Test
  CPU0                 1821.0               1820.5

But when not, the counts aggregated in the metric leader and only 1
column should be shown:

  $ perf stat -M test --metric-only -a sleep 1
   Performance counter stats for 'system wide':

              MiB  Test
                5909.4

         1.001258915 seconds time elapsed

Achieve this by skipping events that aren't metric leaders when
printing column headers and aggregation isn't disabled.

The bug is long standing, the fixes tag is set to a refactor as that
is as far back as is reasonable to backport.

0f06228d4a net/mlx5: Reload only IB representors upon lag disable/enable
On lag disable, the bond IB device along with all of its
representors are destroyed, and then the slaves' representors get reloaded.

In case the slave IB representor load fails, the eswitch error flow
unloads all representors, including ethernet representors, where the
netdevs get detached and removed from lag bond. Such flow is inaccurate
as the lag driver is not responsible for loading/unloading ethernet
representors. Furthermore, the flow described above begins by holding
lag lock to prevent bond changes during disable flow. However, when
reaching the ethernet representors detachment from lag, the lag lock is
required again, triggering the following deadlock:

a static helper method for its internal logic, in symmetry with the
representor unload design.

3d5918477f net/mlx5e: Fix netif state handling
mlx5e_suspend cleans resources only if netif_device_present() returns
true. However, mlx5e_resume changes the state of netif, via
mlx5e_nic_enable, only if reg_state == NETREG_REGISTERED.
In the below case, the above leads to NULL-ptr Oops[1] and memory
leaks:

mlx5e_probe
 _mlx5e_resume
  mlx5e_attach_netdev
   mlx5e_nic_enable  <-- netdev not reg, not calling netif_device_attach()
  register_netdev <-- failed for some reason.
ERROR_FLOW:
 _mlx5e_suspend <-- netif_device_present return false, resources aren't freed :(

Hence, clean resources in this case as well.

====================
net: qede: convert filter code to use extack

This series converts the filter code in the qede driver
to use NL_SET_ERR_MSG_*(extack, ...) for error handling.

Patch 1-12 converts qede_parse_flow_attr() to use extack,
along with all it's static helper functions.

qede_parse_flow_attr() is used in two places:
- qede_add_tc_flower_fltr()
- qede_flow_spec_to_rule()

In the latter call site extack is faked in the same way as
is done in mlxsw (patch 12).

While the conversion is going on, some error messages are silenced
in between patch 1-12. If wanted could squash patch 1-12 in a v3, but
I felt that it would be easier to review as 12 more trivial patches.

Patch 13 and 14, finishes up by converting qede_parse_actions(),
and ensures that extack is propagated to it, in both call contexts.

error message afterwards if one was set.

The extracted error message is then passed on through
DP_NOTICE(), including messages that was earlier issued
with DP_INFO().

160e9d2752 ipv6: sr: fix invalid unregister error path
The error path of seg6_init() is wrong in case CONFIG_IPV6_SEG6_LWTUNNEL
is not defined. In that case if seg6_hmac_init() fails, the
genl_unregister_family() isn't called.

This issue exist since commit 46738b1317 ("ipv6: sr: add option to control
lwtunnel support"), and commit 5559cea2d5 ("ipv6: sr: fix possible
use-after-free and null-ptr-deref") replaced unregister_pernet_subsys()
with genl_unregister_family() in this error path.

7c988176b6 net: openvswitch: fix overwriting ct original tuple for ICMPv6
OVS_PACKET_CMD_EXECUTE has 3 main attributes:
 - OVS_PACKET_ATTR_KEY - Packet metadata in a netlink format.
 - OVS_PACKET_ATTR_PACKET - Binary packet content.
 - OVS_PACKET_ATTR_ACTIONS - Actions to execute on the packet.

OVS_PACKET_ATTR_KEY is parsed first to populate sw_flow_key structure
with the metadata like conntrack state, input port, recirculation id,
etc.  Then the packet itself gets parsed to populate the rest of the
keys from the packet headers.

Whenever the packet parsing code starts parsing the ICMPv6 header, it
first zeroes out fields in the key corresponding to Neighbor Discovery
information even if it is not an ND packet.

It is an 'ipv6.nd' field.  However, the 'ipv6' is a union that shares
the space between 'nd' and 'ct_orig' that holds the original tuple
conntrack metadata parsed from the OVS_PACKET_ATTR_KEY.

ND packets should not normally have conntrack state, so it's fine to
share the space, but normal ICMPv6 Echo packets or maybe other types of
ICMPv6 can have the state attached and it should not be overwritten.

The issue results in all but the last 4 bytes of the destination
address being wiped from the original conntrack tuple leading to
incorrect packet matching and potentially executing wrong actions
in case this packet recirculates within the datapath or goes back
to userspace.

ND fields should not be accessed in non-ND packets, so not clearing
them should be fine.  Executing memset() only for actual ND packets to
avoid the issue.

Initializing the whole thing before parsing is needed because ND packet
may not contain all the options.

The issue only affects the OVS_PACKET_CMD_EXECUTE path and doesn't
affect packets entering OVS datapath from network interfaces, because
in this case CT metadata is populated from skb after the packet is
already parsed.

Fixes: 9dd7f8907c ("openvswitch: Add original direction conntrack tuple to sw_flow_key.")
