* atf_python: support setting interface mtuKristof Provost2025-12-221-0/+6
| | | | | | | | | | | Teach the vnet support code to set interface MTU. Some tests make use of this, so have the framework handle it. Adapt a few pf tests to use this.

* tests: disable transmit checksum offloading for epair interfacesMichael Tuexen2025-09-041-0/+1
| | | | | | | | | | | 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. Reviewed by: kp MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D52379

* aft_python: fix incorrect ndp useKristof Provost2025-05-081-1/+1
| | | | | | | | | | | | | | | | | | | | If we want to clear a flag we have to include '--' before the flag we clear, otherwise ndp will misparse our command (the getopt call will interpret it as another option, and reject it).

* vnet tests: verify that we can load if_epair and if_bridgeKristof Provost2024-07-231-0/+6
| | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | Usually tests are run in sterile environments; however, there is a slight chance that the PATH overrides the utilities used for testing.

* pf: test rules evaluation in the face of multiple IPv6 fragment headersKristof Provost2023-08-041-0/+21
| | | | | | | | | | | | | Send an ICMPv6 echo request packet with multiple IPv6 fragment headers. Set rules to pass all packets, except for ICMPv6 echo requests. pf ought to drop the echo request, but doesn't because it reassembles the packet, and then doesn't handle the second fragment header. In other words: it fails to detect the ICMPv6 echo header.

Additionally, on successful interface creation, interface index and interface name are returned in the `IFLA_NEW_IFINDEX` and `IFLA_IFNAME TLVs, encapsulated in the `NLMSGERR_ATTR_COOKIE`.

* testing: handling non-root users with VNETs in pytest-based tests.Alexander V. Chernikov2023-02-091-0/+3
| | | | | | | | | | | | | | | | Currently isolation and resource requirements are handled directly by the kyua runner, based on the requirements specified by the test. It works well for simple tests, but may cause discrepancy with tests doing complex pre-setups. For example, all tests that perform VNET setups require root access to properly function. This change adds additional handling of the "require_user" property within the python testing framework. Specifically, it requests root access if the test class signals its root requirements and drops privileges to the desired user after performing the pre-setup.

* testing: add ability to specify multi-vnet topologies in the pytest framework.Alexander V. Chernikov2022-07-072-100/+397
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Notable amount of tests related to the packet IO require two VNET jails for proper testing and avoiding side effects for the host system. Additionally, it is often required to run actions in the jails seme-sequentially - waiting for the listener initialisation can be an example of such dependency. This change extends pytest vnet framework to allow defining multi-vnet multi-epair topologies in declarative style, without any need to bother about jail or repair names. All jail creation/teardown, interface creation/teardown and address assignments are handled automatically. Example: TOPOLOGY = { "vnet1": {"ifaces": ["if1", "if2", "if3"]}, "vnet2": {"ifaces": ["if1", "if2", "if3"]}, "if1": {"prefixes6": [("2001:db8:a::1/64", "2001:db8:a::2/64")]}, "if2": {"prefixes6": [("2001:db8:b::1/64", "2001:db8:b::2/64")]}, "if3": {"prefixes6": [("2001:db8:c::1/64", "2001:db8:c::2/64")]}, } def vnet2_handler(self, vnet, obj_map, pipe): ss = VerboseSocketServer("::", self.DEFAULT_PORT) pipe.send("READY") def test_output6_base(self): self.wait_object(second_vnet.pipe) The definitions above will create 2 vnets ("jail_test_output6_base", "jail_test_output6_base_2"), 3 epairs, attached to both first and second jails, set up the IP addresses for each epair, spawn another process for vnet2_handler and pass control to vnet2_handler and test_output6_base. Both processes can pass objects between each other using pre-created pipes. Differential Revision: https://reviews.freebsd.org/D35708
* testing: Add basic atf support to pytest.Alexander V. Chernikov2022-06-257-0/+861
Implementation consists of the pytest plugin implementing ATF format and a simple C++ wrapper, which reorders the provided arguments from ATF format to the format understandable by pytest. Each test has this wrapper specified after the shebang. When kyua executes the test, wrapper calls pytest, which loads atf plugin, does the work and returns the result. Additionally, a separate python "package", `/usr/tests/atf_python` has been added to collect code that may be useful across different tests. Current limitations: * Opaque metadata passing via X-Name properties. Require some fixtures to write * `-s srcdir` parameter passed by the runner is ignored. * No `atf-c-api(3)` or similar - relying on pytest framework & existing python libraries * No support for `atf_tc_<get|has>_config_var()` & `atf_tc_set_md_var()`. Can be probably implemented with env variables & autoload fixtures Differential Revision: https://reviews.freebsd.org/D31084 Reviewed by: kp, ngie
