* rtnetlink: Add native SR-IOV VF statusKevin Bowling13 days2-0/+150
| | | | | | | | | | | | | | | | | | | | | | Add a transport neutral kernel snapshot for NIC-specific SR-IOV VF status and an optional iflib provider method. Providers gather state under driver defined synchronization. Honor RTEXT_FILTER_VF on RTM_GETLINK requests and encode the status as native typed route Netlink attributes. Represent VFs, driver namespaces, and namespace fields as directly repeated nested attributes. Presence masks in consumers can distinguish omission from false or zero. Drivers may add custom status under stable, versioned namespaces. The named, typed representation lets generic transports and consumers carry or display fields without knowing their driver-specific schemas, while the driver retains ownership of their names and meanings. Document the ABI and add parser and RTM_GETLINK coverage.

* rtnetlink: Report SR-IOV VF statusKevin Bowling2026-08-092-0/+145
| | | | | | | | | | | | | | | | Honor RTEXT_FILTER_VF on RTM_GETLINK requests and expose the versioned SR-IOV VF status through typed nested FreeBSD attributes. Report IFLA_NUM_VF with a successful requested query and preserve per-provider errors in the status container. Map the common nvlist schema to native integer, boolean, string, and binary attributes. Carry namespaced driver extensions as packed versioned nvlists so adding a driver-specific field does not expand the common netlink ABI. Add SNL parsers, parser verification, a constructed nested-status test, and an RTM_GETLINK test for an interface without SR-IOV support. Document the query contract and every attribute.

| | | | | | | | | | | | | | | | | Current radix-based implementation of lookup tables in ipfw does not support non-contiguous prefixes while this type of lookup is needed to write CPU-effective firewall configurations. For some of the cases we can reach the goal using a masked table lookup by adding masked (e.g. zero non-significant bits) records into a table and then zero non-significant bits in lookup key prior to making a table lookup.

* 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.

| | | | | | | | | | | | | | | | 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.
