without PVID
Recent discussions around commit ad1afb003939 ("vlan_dev: VLAN 0 should
be treated as "no vlan tag" (802.1p packet)") have sparked the question
what happens with the DSA (and possibly other switchdev) data path when
the bridge says that ports should have no PVID VLAN, but the 8021q
module, as the result of a NETDEV_UP event, decides it should add VID 0
to the RX filter of those bridge ports. Do those bridge ports receive
packets tagged with VID 0 or not, now? We don't know, there is no test.
In the veth realm, this passes trivially, because veth is not VLAN
filtering and this, the 8021q module lacks the instinct to add VID 0 in
the first place.
In the realm of VLAN filtering NICs with no switchdev offload, this
should also pass, because the VLAN groups of the software bridge are
consulted, where it can clearly be seen that a PVID is missing, even
though the packet was initially accepted by the NIC.
The test only poses a challenge for switchdev drivers, which usually
have to program to hardware both VLANs from RX filtering, as well as
from switchdev. Especially when a switchdev port joins a VLAN-aware
bridge, it is unavoidable that it gains the NETIF_F_HW_VLAN_CTAG_FILTER
feature, i.e. any 8021q uppers that the bridge port may have must also
be committed to the RX filtering table of the interface. When a
VLAN-tagged packet is physically received by the port, it is initially
indistinguishable whether it will reach the bridge data path or the
8021q upper data path.
That is rather the final step of the new tests that we introduce.
We need to build context up to that stage, which means the following:
- we need to test that 802.1p (VID 0) tagged traffic is received in the
first place (on bridge ports with a valid PVID). This is the "8021p"
test.
- we need to test that the usual paths of reaching a configuration with
no PVID on a bridge port are all covered and they all reach the same
state.

RSS contexts are used to shard work across multiple queues for an
application using io_uring zero copy receive. Add a test case checking
that steering flows into an RSS context works.
Until I add multi-thread support to the selftest binary, this test case
only has 1 queue in the RSS context.

After recent changes in the VM network stack, the host fails to
display the IP addresses of the VM. As a result the "IP Addresses"
column in the "Networking" tab in the Windows Hyper-V Manager is
empty. This is caused by a change in the expected output of the
"ip route show" command. Previously the gateway address was shown
in the third row. Now the gateway addresses might be split into
several lines of output. As a result, the string "ra" instead of
an IP address is sent to the host.
To me more specific, a VM with the wellknown wicked network
managing tool still shows the expected output in recent openSUSE
Tumbleweed snapshots:

Adjust the route parsing to use a single line for each line of
output. Also use a single shell invocation to retrieve both IPv4
and IPv6 information. The actual IP addresses are expected after
the "via" keyword.

Some distributions, such as centos stream 9, still have a version of
coreutils which does not yet support the %Hr and %Lr formats for stat(1)
[1, 2]. Running ublk selftests on these distributions results in the
following error in tests that use the _get_disk_dev_t helper:
line 23: ?r: syntax error: operand expected (error token is "?r")
To better accommodate older distributions, rewrite _get_disk_dev_t to
use the much older %t and %T formats for stat instead.

When running diag.sh in a loop, chk_dump_one will report the following
"grep: write error":
13 ....chk 2 cestab [ OK ]
grep: write error
14 ....chk dump_one [ OK ]
15 ....chk 2->0 msk in use after flush [ OK ]
16 ....chk 2->0 cestab after flush [ OK ]
This error is caused by a broken pipe. When the output of 'ss' is processed
by grep, 'head -n 1' will exit immediately after getting the first line,
causing the subsequent pipe to close. At this time, if 'grep' is still
trying to write data to the closed pipe, it will trigger a SIGPIPE signal,
causing a write error.
One solution is not to use this problematic "head -n 1" command, but to use
mptcp_lib_get_info_value() helper defined in mptcp_lib.sh to get the value
of 'token'.

"sockmap_ktls disconnect_after_delete" test has been failing on BPF CI
after recent merges from netdev:
* https://github.com/kernel-patches/bpf/actions/runs/14458537639
* https://github.com/kernel-patches/bpf/actions/runs/14457178732
It happens because disconnect has been disabled for TLS [1], and it
renders the test case invalid.
Removing all the test code creates a conflict between bpf and

When the select of PRIME_MUMBERS was removed from it's KUnit test
Kconfig nothing was added to the KUnit configs, meaning that when run
via the KUnit runner the tests are neither built nor run. Add
PRIME_NUMBERS to all_tests.config so they are enabled when the KUnit
runner builds the kernel.

Various new families and my recent work on rtnetlink missed
adding dependencies on C headers. If the system headers are
up to date or don't include a given header at all this doesn't
make a difference. But if the system headers are in place but
stale - compilation will break.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing fixes from Steven Rostedt:
- Initialize hash variables in ftrace subops logic
The fix that simplified the ftrace subops logic opened a path where
some variables could be used without being initialized, and done
subtly where the compiler did not catch it. Initialize those
variables to the EMPTY_HASH, which is the default hash.
- Reinitialize the hash pointers after they are freed
Some of the hash pointers in the subop logic were freed but may still
be referenced later. To prevent use-after-free bugs, initialize them
back to the EMPTY_HASH.
- Free the ftrace hashes when they are replaced
The fix that simplified the subops logic updated some hash pointers,
but left the original hash that they were pointing to where they are
no longer used. This caused a memory leak. Free the hashes that are
pointed to by the pointers when they are replaced.
- Fix size initialization of ftrace direct function hash
The ftrace direct function hash used by BPF initialized the hash size
incorrectly. It checked the size of items to a hard coded 32, which
made the hash bit size of 5. The hash size is supposed to be limited
by the bit size of the hash, as the bitmask is allowed to be greater
than 5. Rework the size check to first pass the number of elements to
fls() and then compare that to FTRACE_HASH_MAX_BITS before allocating
the hash.
- Fix format output of ftrace_graph_ent_entry event
The field depth of the ftrace_graph_ent_entry event is of size 4 but
the output showed it as unsigned long and use "%lu". Change it to
unsigned int and use "%u" in the print format that is displayed to
user space.
- Fix the trace event filter on strings
Events can be filtered on numbers or string values. The return value
checked from strncpy_from_kernel_nofault() and
strncpy_from_user_nofault() was used to determine if reading the
strings would fault or not. It would return fault if the value was
non zero, which is basically meant that it was always considering the
read as a fault.
- Add selftest to test trace event string filtering
In order to catch the breakage of the string filtering, add a self
test to make sure that it continues to work.

Testing revealed the following error message for a CXL memdev that has
Feature support:
[ 56.690430] cxl mem0: Resources present before probing
Attach the allocation of cxl_fwctl to the parent device of cxl_memdev.
devm_add_* calls for cxl_memdev should not happen before the memdev
probe function or outside the scope of the memdev driver.
cxl_test missed this bug because cxl_test always arranges for the
cxl_mem driver to be loaded before cxl_mock_mem runs. So the driver core
always finds the devres list idle in that case.

Commit df6f8c4d72ae ("selftests/pcie_bwctrl: Add 'set_pcie_speed.sh' to

helper that is only being called by set_pcie_cooling_state.sh, not a test
case itself. When set_pcie_speed.sh is in TEST_PROGS, selftest harness will
execute also it leading to bwctrl selftest errors:
# selftests: pcie_bwctrl: set_pcie_speed.sh
# cat: /cur_state: No such file or directory
not ok 2 selftests: pcie_bwctrl: set_pcie_speed.sh # exit=1
Place set_pcie_speed.sh into TEST_FILES instead to have it included into

The ovpn-cli tool can be compiled and used as selftest for the ovpn
kernel module.
[NOTE: it depends on libmedtls for decoding base64-encoded keys]
ovpn-cli implements the netlink and RTNL APIs and can thus be integrated
in any script for more automated testing.
Along with the tool, a bunch of scripts are provided that perform basic
functionality tests by means of network namespaces.
These scripts take part to the kselftest automation.
The output of the scripts, which will appear in the kselftest
reports, is a list of steps performed by the scripts plus some
output coming from the execution of `ping`, `iperf` and `ovpn-cli`
itself.
In general it is useful only in case of failure, in order to
understand which step has failed and why.
Please note: since peer sockets are tied to the userspace
process that created them (i.e. exiting the process will result
in closing the socket), every run of ovpn-cli that created
one will go to background and enter pause(), waiting for the
signal which will allow it to terminate.
Termination is accomplished at the end of each script by
issuing a killall command.
