selftests: drv-net: Fix remote command checking in require_cmd()

2025-07-25T01:52:00+00:00

The require_cmd() method was checking for command availability locally
even when remote=True was specified, due to a missing host parameter.

Fix by passing host=self.remote when checking remote command
availability, ensuring commands are verified on the correct host.

selftests: drv-net: replace the rpath helper with Path objects

2025-03-31T23:44:25+00:00

The single letter + "path" helpers do not have many fans (see Link).
Use a Path object with a better name. test_dir is the replacement
for rpath(), net_lib_dir is a new path of the $ksft/net/lib directory.

The Path() class overloads the "/" operator and can be cast to string
automatically, so to get a path to a file tests can do:

    path = env.test_dir / "binary"

selftests: drv-net: add tests for napi IRQ affinity notifiers

2025-02-27T03:51:38+00:00

Add tests to check that the napi retained the IRQ after down/up,
multiple changes in the number of rx queues and after
attaching/releasing XDP program.

Tested on ice and idpf:

   # NETIF= tools/testing/selftests/drivers/net/hw/irq.py

    ok 4 irq.check_down
    # Totals: pass:4 fail:0 xfail:0 xpass:0 skip:0 error:0

selftests: drv-net: store addresses in dict indexed by ipver

2025-02-20T03:08:50+00:00

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.

We already record output of ip link for NETIF in env for easy access.
Record the detailed version. TSO test will want to know the max tso size.

selftests: drv-net: resolve remote interface name

2025-02-20T03:08:49+00:00

Find out and record in env the name of the interface which remote host
will use for the IP address provided via config.

Interface name is useful for mausezahn and for setting up tunnels.

selftests: drv-net: add helper for path resolution

2025-02-11T03:10:10+00:00

Refering to C binaries from Python code is going to be a common
need. Add a helper to convert from path in relation to the test.
Meaning, if the test is in the same directory as the binary, the
call would be simply: cfg.rpath("binary").

The helper name "rpath" is not great. I can't think of a better
name that would be accurate yet concise.

We have separate Env classes for local tests and tests with a remote
endpoint. Make it easier to share the code by creating a base class.
Make env loading a method of this class.

selftests: drv-net: test drivers sleeping in ndo_get_stats64

2025-01-09T03:36:46+00:00

Most of our tests use rtnetlink to read device stats, so they
don't expose the drivers much to paths in which device stats
are read under RCU. Add tests which hammer profcs reads to
make sure drivers:
 - don't sleep while reporting stats,
 - can handle parallel reads,
 - can handle device going down while reading.

Set ifname on the env class in NetDrvEnv, we already do that
in NetDrvEpEnv.
