if_epair: support IFCAP_MEXTPG

2026-07-08T07:23:17+00:00

Enable IFCAP_MEXTPG by default, which may bring performance benefits.
Allow it to be disabled, and when disabled assert that we do not receive
any mbufs with M_EXTPG set. This is useful for testing.
Default the tests to disabling MEXTPG support.

tests/sendfile_helper: support remote connection

2026-07-08T07:23:16+00:00

In order to use the sendfile_helper program in a pf test script that
requires non-loopback interfaces, add functionality to sendfile with a
TCP socket that is connected to a remote host.
The behavior for unix sockets and TCP loopback sockets is unchanged.

tests/sendfile: move the helper program to common

2026-07-08T07:23:16+00:00

In order to reuse the sendfile_helper program in pf tests, move it
to tests/sys/common directory, indicatint that it is also used from
another places than sys/kern.
Also make the readlen variable static.

tests: detect built-in modules

2025-11-26T10:27:47+00:00

When checking vnet test prerequisites we check if if_epair and if_bridge are
available, but we only checked for loadable modules. It's possible for these to
be built into the kernel instead.

tests: disable transmit checksum offloading for epair interfaces

2025-09-04T11:52:37+00:00

When transmit checksum offloading is enabled, if_epair does not
compute checksums, it just marks packets that this computation still
needs to be done. However, some test cases verify the checksum.
Therefore disable this for IPv4 and IPv6.

vnet tests: verify that we can load if_epair and if_bridge

2024-07-23T13:57:25+00:00

We're going to start running many of the vnet tests in nested jails (so they
can run in parallel). That means the tests won't be able to load kernel modules,
which we commonly do for if_epair and if_bridge.

Just assume that all vnet tests need this, because so many of them do that we
don't want to manually annotate all of them.
This is essentially a no-op on non-nested tests.

Do the same for the python test framework.

While here also have pflog_init actually call pft_init. While having pflog
loaded implies we have pf too pft_init also checks for vimage support, and now
for if_epair.

vnet tests: check for if_bridge.ko

2024-06-04T20:16:56+00:00

A number of tests create a bridge, but did not check if if_bridge.ko is loaded.

We usually get away with that, because `ifconfig bridge create` autoloads the
module, but if we run the tests in a jail (e.g. because of kyua's upcoming
execenv.jail.params feature) we can't load the module and these tests can fail.

Check if the module is loaded, skip the test if it is not.
