shellcheck recently helped to find an issue where a wrong variable name
was used. It is then good to fix the other harmless issues in order to
spot "real" ones later.
Here, three categories of warnings are ignored:
- SC2317: Command appears to be unreachable. The cleanup() function is
invoke indirectly via the EXIT trap.
- SC2034: Variable appears unused. The check_expected_one() function
takes the name of the variable in argument but it ends up reading the
content: indirect usage.
- SC2086: Double quote to prevent globbing and word splitting. This is
recommended but the current usage is correct and there is no need to
do all these modifications to be compliant with this rule.
One error has been fixed with SC2181: Check exit code directly with e.g.
'if ! mycmd;', not indirectly with $?.

This patch adds a runnable version of one of the races described by
Kumar in [0]. Specifically, this interleaving:
(rbtree1 and list head protected by lock1, rbtree2 protected by lock2)
Prog A Prog B
======================================
n = bpf_obj_new(...)
m = bpf_refcount_acquire(n)
kptr_xchg(map, m)
m = kptr_xchg(map, NULL)
lock(lock2)
bpf_rbtree_add(rbtree2, m->r, less)
unlock(lock2)
lock(lock1)
bpf_list_push_back(head, n->l)
/* make n non-owning ref */
bpf_rbtree_remove(rbtree1, n->r)
unlock(lock1)
The above interleaving, the node's struct bpf_rb_node *r can be used to
add it to either rbtree1 or rbtree2, which are protected by different
locks. If the node has been added to rbtree2, we should not be allowed
to remove it while holding rbtree1's lock.
Before changes in the previous patch in this series, the rbtree_remove
in the second part of Prog A would succeed as the verifier has no way of
knowing which tree owns a particular node at verification time. The
addition of 'owner' field results in bpf_rbtree_remove correctly
failing.
The test added in this patch splits "Prog A" above into two separate BPF
programs - A1 and A2 - and uses a second mapval + kptr_xchg to pass n
from A1 to A2 similarly to the pass from A1 to B. If the test is run
without the fix applied, the remove will succeed.
Kumar's example had the two programs running on separate CPUs. This
patch doesn't do this as it's not necessary to exercise the broken
behavior / validate fixed behavior.

As described by Kumar in [0], in shared ownership scenarios it is
necessary to do runtime tracking of {rb,list} node ownership - and
synchronize updates using this ownership information - in order to
prevent races. This patch adds an 'owner' field to struct bpf_list_node
and bpf_rb_node to implement such runtime tracking.
The owner field is a void * that describes the ownership state of a
node. It can have the following values:
NULL - the node is not owned by any data structure
BPF_PTR_POISON - the node is in the process of being added to a data
structure
ptr_to_root - the pointee is a data structure 'root'
(bpf_rb_root / bpf_list_head) which owns this node
The field is initially NULL (set by bpf_obj_init_field default behavior)
and transitions states in the following sequence:
Insertion: NULL -> BPF_PTR_POISON -> ptr_to_root
Removal: ptr_to_root -> NULL
Before a node has been successfully inserted, it is not protected by any
root's lock, and therefore two programs can attempt to add the same node
to different roots simultaneously. For this reason the intermediate
BPF_PTR_POISON state is necessary. For removal, the node is protected
by some root's lock so this intermediate hop isn't necessary.
Note that bpf_list_pop_{front,back} helpers don't need to check owner
before removing as the node-to-be-removed is not passed in as input and
is instead taken directly from the list. Do the check anyways and
WARN_ON_ONCE in this unexpected scenario.
Selftest changes in this patch are entirely mechanical: some BTF
tests have hardcoded struct sizes for structs that contain
bpf_{list,rb}_node fields, those were adjusted to account for the new
sizes. Selftest additions to validate the owner field are added in a
further patch in the series.

When looking at the TC selftest reports, I noticed one test was failing
because /proc/net/nf_conntrack was not available.

Could not match regex pattern. Verify command output:

It is only available if NF_CONNTRACK_PROCFS kconfig is set. So the issue
can be fixed simply by adding it to the list of required kconfig.

When looking for something else in LKFT reports [1], I noticed most of
the tests were skipped because the "teardown stage" did not complete
successfully.
Pedro found out this is due to the fact CONFIG_NF_FLOW_TABLE is required
but not listed in the 'config' file. Adding it to the list fixes the
issues on LKFT side. CONFIG_NET_ACT_CT is now set to 'm' in the final

When looking for something else in LKFT reports [1], I noticed that the
TC selftest ended with a timeout error:
not ok 1 selftests: tc-testing: tdc.sh # TIMEOUT 45 seconds
The timeout had been introduced 3 years ago, see the Fixes commit below.
This timeout is only in place when executing the selftests via the
kselftests runner scripts. I guess this is not what most TC devs are
using and nobody noticed the issue before.
The new timeout is set to 15 minutes as suggested by Pedro [2]. It looks

While it probably doesn't make a huge difference given the current KUnit
coverage we will get the best coverage of arm64 architecture features if
we specify -cpu=max rather than picking a specific CPU, this will include
all architecture features that qemu supports including many which have not
yet made it into physical implementations.
Due to performance issues emulating the architected pointer authentication
algorithm it is recommended to use the implementation defined algorithm
that qemu has instead, this should make no meaningful difference to the
coverage and will run the tests faster.

The default KUnit build options are not supposed to enable any
subsystems that were not already enabled but the topology code is a
library which is generally selected by drivers that want to use it.
Since KUnit is frequently run in virtual environments with minimal
driver support this makes it difficult to enable the toplogy tests so
provide an explicit Kconfig option which can be directly enabled when
using KUnit, and also include this in the KUnit all_tests.config.

Currently, the kernel boot parameters specified by the kvm.sh --bootargs
parameter are placed near the beginning of the -append list that is

The build failure reported in [1] occurred because commit <9fc96c7c19df>
("selftests: error out if kernel header files are not yet built") added
a new "kernel_header_files" dependency to "all", and that triggered
another, pre-existing problem. Specifically, the arm64 selftests
override the emit_tests target, and that override improperly declares
itself to depend upon the "all" target.
This is a problem because the "emit_tests" target in lib.mk was not
intended to be overridden. emit_tests is a very simple, sequential build
target that was originally invoked from the "install" target, which in
turn, depends upon "all".
That approach worked for years. But with 9fc96c7c19df in place,
emit_tests failed, because it does not set up all of the elaborate
things that "install" does. And that caused the new
"kernel_header_files" target (which depends upon $(KBUILD_OUTPUT) being
correct) to fail.
Some detail: The "all" target is .PHONY. Therefore, each target that
depends on "all" will cause it to be invoked again, and because
dependencies are managed quite loosely in the selftests Makefiles, many
things will run, even "all" is invoked several times in immediate
succession. So this is not a "real" failure, as far as build steps go:
everything gets built, but "all" reports a problem when invoked a second
time from a bad environment.
To fix this, simply remove the unnecessary "all" dependency from the
overridden emit_tests target. The dependency is still effectively
honored, because again, invocation is via "install", which also depends
upon "all".
An alternative approach would be to harden the emit_tests target so that
it can depend upon "all", but that's a lot more complicated and hard to
get right, and doesn't seem worth it, especially given that emit_tests
should probably not be overridden at all.

The riscv selftests (which were modeled after the arm64 selftests) are
improperly declaring the "emit_tests" target to depend upon the "all"
target. This approach, when combined with commit 9fc96c7c19df
("selftests: error out if kernel header files are not yet built"), has
caused build failures [1] on arm64, and is likely to cause similar
failures for riscv.
To fix this, simply remove the unnecessary "all" dependency from the

When run under run_vmtests.sh, test scripts were failing to run with
"permission denied" due to the scripts not being executable.
It is also annoying not to be able to directly invoke run_vmtests.sh,
which is solved by giving also it the execute permission.

This tests whether addition and deletion of a VLAN upper that coincides
with the current PVID setting throws off forwarding.
This selftests is specifically geared towards offloading drivers. In
particular, mlxsw used to fail this selftest, and an earlier patch in this
patchset fixes the issue. However, there's nothing HW-specific in the test
itself (it absolutely is supposed to pass on SW datapath), and therefore it
is put into the generic forwarding directory.

Add an alternative path involving VLAN 777 instead of the current 555. Then
add tests that verify that marking 777 as PVID makes the 555 path not work,
and the 777 path work.

This test relies on PVID being configured on the bridge itself. Thus when
it is deconfigured, the system should lose the ability to forward traffic.
Later when it is added again, the ability to forward traffic should be
regained. Add tests to exercise these configuration changes and verify
results.

Use a new env var speed instead of using 'speed' argument of run_tests()
and do_transfer(). It can be set with 'fast', 'slow', or the actual speed
number:
run_tests $ns1 $ns2 10.0.1.1 slow
->
speed=slow \
run_tests $ns1 $ns2 10.0.1.1.
