The triggers set in trigger-onchange-action-hist.tc and
trigger-snapshot-action-hist.tc are not cleaned up at the end. These tests
can also be done in instances and without cleaning up the triggers, the
instances can not be removed as they are still "busy".

For the tests that have both a README attribute as well as the instance
flag to run the tests as an instance, the instance version will always
exit with UNSUPPORTED. That's because the instance directory does not
contain a README file. Currently, the tests check for a README file in the
directory that the test runs in and if there's a requirement for something
to be present in the README file, it will not find it, as the instance
directory doesn't have it.
Have the tests check if the current directory is an instance directory,
and if it is, check two directories above the current directory for the
README file:
/sys/kernel/tracing/README
/sys/kernel/tracing/instances/foo/../../README

Add a simple test for TSO. Send a few MB of data and check device
stats to verify that the device was performing segmentation.
Do the same thing over a few tunnel types.
Injecting GSO packets directly would give us more ability to test
corner cases, but perhaps starting simple is good enough?
# ./ksft-net-drv/drivers/net/hw/tso.py

Note that the test currently depends on the driver reporting
the LSO count via qstat, which appears to be relatively rare
(virtio, cisco/enic, sfc/efc; but virtio needs host support).

Looks like more and more tests want to iterate over IP version,
run the same test over ipv4 and ipv6. The current naming of
members in the env class makes it a bit awkward, we have
separate members for ipv4 and ipv6 parameters.
Store the parameters inside dicts, so that tests can easily
index them with ip version.

The kprobe_multi feature was disabled on ARM64 due to the lack of fprobe
support.
The fprobe rewrite on function_graph has been recently merged and thus
brought support for fprobes on arm64. This then enables kprobe_multi
support on arm64, and so the corresponding tests can now be run on this
architecture.
Remove the tests depending on kprobe_multi from DENYLIST.aarch64 to
allow those to run in CI. CONFIG_FPROBE is already correctly set in

A test case with ridiculously deep bpf_for() nesting and
a conditional update of a stack location.
Consider the innermost loop structure:
1: bpf_for(o, 0, 10)
2: if (unlikely(bpf_get_prandom_u32()))
3: buf[0] = 42;
4: <exit>
Assuming that verifier.c:clean_live_states() operates w/o change from
the previous patch (e.g. as on current master) verification would
proceed as follows:
- at (1) state {buf[0]=?,o=drained}:
- checkpoint
- push visit to (2) for later
- at (4) {buf[0]=?,o=drained}
- pop (2) {buf[0]=?,o=active}, push visit to (3) for later
- at (1) {buf[0]=?,o=active}
- checkpoint
- push visit to (2) for later
- at (4) {buf[0]=?,o=drained}
- pop (2) {buf[0]=?,o=active}, push visit to (3) for later
- at (1) {buf[0]=?,o=active}:
- checkpoint reached, checkpoint's branch count becomes 0
- checkpoint is processed by clean_live_states() and
becomes {o=active}
- pop (3) {buf[0]=42,o=active}
- at (1), {buf[0]=42,o=active}
- checkpoint
- push visit to (2) for later
- at (4) {buf[0]=42,o=drained}
- pop (2) {buf[0]=42,o=active}, push visit to (3) for later
- at (1) {buf[0]=42,o=active}, checkpoint reached
- pop (3) {buf[0]=42,o=active}
- at (1) {buf[0]=42,o=active}:
- checkpoint reached, checkpoint's branch count becomes 0
- checkpoint is processed by clean_live_states() and
becomes {o=active}
- ...
Note how clean_live_states() converted the checkpoint
{buf[0]=42,o=active} to {o=active} and it can no longer be matched
against {buf[0]=<any>,o=active}, because iterator based states
are compared using stacksafe(... RANGE_WITHIN), that requires
stack slots to have same types. At the same time there are
still states {buf[0]=42,o=active} pushed to DFS stack.
This behaviour becomes exacerbated with multiple nesting levels,
here are veristat results:
- nesting level 1: 69 insns
- nesting level 2: 258 insns
- nesting level 3: 900 insns
- nesting level 4: 4754 insns
- nesting level 5: 35944 insns
- nesting level 6: 312558 insns
- nesting level 7: 1M limit

A somewhat cumbersome test case sensitive to correct copying of
bpf_verifier_state->loop_entry fields in
verifier.c:copy_verifier_state().
W/o the fix from a previous commit the program is accepted as safe.
1: /* poison block */
2: if (random() != 24) { // assume false branch is placed first
3: i = iter_new();
4: while (iter_next(i));
5: iter_destroy(i);
6: return;
7: }
8:
9: /* dfs_depth block */
10: for (i = 10; i > 0; i--);
11:
12: /* main block */
13: i = iter_new(); // fp[-16]
14: b = -24; // r8
15: for (;;) {
16: if (iter_next(i))
17: break;
18: if (random() == 77) { // assume false branch is placed first
19: *(u64 *)(r10 + b) = 7; // this is not safe when b == -25
20: iter_destroy(i);
21: return;
22: }
23: if (random() == 42) { // assume false branch is placed first
24: b = -25;
25: }
26: }
27: iter_destroy(i);
The goal of this example is to:
(a) poison env->cur_state->loop_entry with a state S,
such that S->branches == 0;
(b) set state S as a loop_entry for all checkpoints in
/* main block */, thus forcing NOT_EXACT states comparisons;
(c) exploit incorrect loop_entry set for checkpoint at line 18
by first creating a checkpoint with b == -24 and then
pruning the state with b == -25 using that checkpoint.
The /* poison block */ is responsible for goal (a).
It forces verifier to first validate some unrelated iterator based
loop, which leads to an update_loop_entry() call in is_state_visited(),
which places checkpoint created at line 4 as env->cur_state->loop_entry.
Starting from line 8, the branch count for that checkpoint is 0.
The /* dfs_depth block */ is responsible for goal (b).
It abuses the fact that update_loop_entry(cur, hdr) only updates
cur->loop_entry when hdr->dfs_depth <= cur->dfs_depth.
After line 12 every state has dfs_depth bigger then dfs_depth of
poisoned env->cur_state->loop_entry. Thus the above condition is never
true for lines 12-27.
The /* main block */ is responsible for goal (c).
Verification proceeds as follows:
- checkpoint {b=-24,i=active} created at line 16;
- jump 18->23 is verified first, jump to 19 pushed to stack;
- jump 23->26 is verified first, jump to 24 pushed to stack;
- checkpoint {b=-24,i=active} created at line 15;
- current state is pruned by checkpoint created at line 16,
this sets branches count for checkpoint at line 15 to 0;
- jump to 24 is popped from stack;
- line 16 is reached in state {b=-25,i=active};
- this is pruned by a previous checkpoint {b=-24,i=active}:
- checkpoint's loop_entry is poisoned and has branch count of 0,
hence states are compared using NOT_EXACT rules;
- b is not marked precise yet.

Tests use the root network namespace, so they aren't fully independent
of each other. For instance, the index of the created veth interfaces
is incremented every time a new test is launched.
Wrap the network topology in a network namespace to ensure full
isolation. Use the append_tid() helper to ensure the uniqueness of this
namespace's name during parallel runs.
Remove the use of the append_tid() on the veth names as they now belong
to an already unique namespace.
Simplify cleanup_network() by directly deleting the namespaces

The network configuration is defined by a table of struct
veth_configuration. This isn't convenient if we want to add a network
configuration that isn't linked to a veth pair.
Create a struct net_configuration that holds the veth_configuration
table to ease adding new configuration attributes in upcoming patch.

Following a similar rationale as commit e4835f1da425f ("kunit: tool:
Build compile_commands.json"), make a common developer tool available by
default for KUnit users.
Compared to compile_commands.json, there is a little more work to be
done to build the GDB scripts. Is it enough to affect development cycle
duration? Unscientific evaluation:
rm -rf .kunit; time tools/testing/kunit/kunit.py build --kunitconfig ./lib/kunit/.kunitconfig --jobs 96
Without this patch it took 14.77s, with this patch it took 14.83. So,
although `make scripts_gdb` is pretty slow, presumably most of that is
just the overhead of running Kbuild at all, actually building the
scripts is approximately free.
Note also, to actually get the GDB scripts the user needs to enable
CONFIG_SCRIPTS_GDB, but building the scripts_gdb target without that is
still harmless.

This helper could be useful to more than just forwarding tests.
Move it upstairs and port over to log_test_skip().
Split the function into two parts: the bit that actually checks and
reports skip, which is in a new function check_command(). And a bit
that exits the test script if the check fails. This allows users
consistent checking behavior while giving an option to bail out from
a single test without bailing out of the whole script.

Verify that for a connectible AF_VSOCK socket, merely having a transport
assigned is insufficient; socket must be connected for the sockmap to
accept.
This does not test datagram vsocks. Even though it hardly matters. VMCI is
the only transport that features VSOCK_TRANSPORT_F_DGRAM, but it has an
unimplemented vsock_transport::readskb() callback, making it unsupported by
BPF/sockmap.

Commit 515745445e92 ("selftest/bpf: Add test for vsock removal from sockmap
on close()") added test that checked if proto::close() callback was invoked
on AF_VSOCK socket release. I.e. it verified that a close()d vsock does
indeed get removed from the sockmap.
It was done simply by creating a socket pair and attempting to replace a
close()d one with its peer. Since, due to a recent change, sockmap does not
allow updating index with a non-established connectible vsock, redo it with
a freshly established one.

When testing if we should try to compact memory or drop caches before we
run the THP or HugeTLB tests we use | as an or operator. This doesn't
work since run_vmtests.sh is written in shell where this is used to pipe
the output of the first argument into the second. Instead use the shell's
-o operator.

Test referenced kptr acquired through struct_ops argument tagged with
"__ref". The success case checks whether 1) a reference to the correct
type is acquired, and 2) the referenced kptr argument can be accessed in
multiple paths as long as it hasn't been released. In the fail cases,
we first confirm that a referenced kptr acquried through a struct_ops
argument is not allowed to be leaked. Then, we make sure this new
referenced kptr acquiring mechanism does not accidentally allow referenced
kptrs to flow into global subprograms through their arguments.
