[PATCH 1/3] kunit: tool: readability tweaks in KernelCI json generation logic

by Daniel Latypov

Use a more idiomatic check that a list is non-empty (`if mylist:`) and sinmplify the function body by dedenting and using a dict to map between the kunit TestStatus enum => KernelCI json status string. The dict hopefully makes it less likely to have bugs like commit 9a6bb30a8830 ("kunit: tool: fix --json output for skipped tests"). Signed-off-by: Daniel Latypov <dlatypov(a)google.com> --- Note: this series is based on my earlier set of kunit tool cleanups for 5.18, https://lore.kernel.org/linux-kselftest/20220118190922.1557074-1-dlatypov@g… There's no interesting semantic dependency, just some boring merge conflicts, specifically with patch #4 there, https://lore.kernel.org/linux-kselftest/20220118190922.1557074-5-dlatypov@g… --- tools/testing/kunit/kunit_json.py | 20 ++++++++++---------- 1 file changed, 10 insertions(+), 10 deletions(-) diff --git a/tools/testing/kunit/kunit_json.py b/tools/testing/kunit/kunit_json.py index 24d103049bca..14a480d3308a 100644 --- a/tools/testing/kunit/kunit_json.py +++ b/tools/testing/kunit/kunit_json.py @@ -16,24 +16,24 @@ from typing import Any, Dict JsonObj = Dict[str, Any] +_status_map: Dict[TestStatus, str] = { + TestStatus.SUCCESS: "PASS", + TestStatus.SKIPPED: "SKIP", + TestStatus.TEST_CRASHED: "ERROR", +} + def _get_group_json(test: Test, def_config: str, build_dir: str) -> JsonObj: sub_groups = [] # List[JsonObj] test_cases = [] # List[JsonObj] for subtest in test.subtests: - if len(subtest.subtests): + if subtest.subtests: sub_group = _get_group_json(subtest, def_config, build_dir) sub_groups.append(sub_group) - else: - test_case = {"name": subtest.name, "status": "FAIL"} - if subtest.status == TestStatus.SUCCESS: - test_case["status"] = "PASS" - elif subtest.status == TestStatus.SKIPPED: - test_case["status"] = "SKIP" - elif subtest.status == TestStatus.TEST_CRASHED: - test_case["status"] = "ERROR" - test_cases.append(test_case) + continue + status = _status_map.get(subtest.status, "FAIL") + test_cases.append({"name": subtest.name, "status": status}) test_group = { "name": test.name, -- 2.35.1.473.g83b2b277ed-goog

[PATCH bpf-next v2 0/3] New BPF helpers to accelerate synproxy

by Maxim Mikityanskiy

The first patch of this series is an improvement to the existing syncookie BPF helper. The two other patches add new functionality that allows XDP to accelerate iptables synproxy. v1 of this series [1] used to include a patch that exposed conntrack lookup to BPF using stable helpers. It was superseded by series [2] by Kumar Kartikeya Dwivedi, which implements this functionality using unstable helpers. The second patch adds new helpers to issue and check SYN cookies without binding to a socket, which is useful in the synproxy scenario. The third patch adds a selftest, which consists of a script, an XDP program and a userspace control application. The XDP program uses socketless SYN cookie helpers and queries conntrack status instead of socket status. The userspace control application allows to tune parameters of the XDP program. This program also serves as a minimal example of usage of the new functionality. The draft of the new functionality was presented on Netdev 0x15 [3]. v2 changes: Split into two series, submitted bugfixes to bpf, dropped the conntrack patches, implemented the timestamp cookie in BPF using bpf_loop, dropped the timestamp cookie patch.

[PATCH net-next v4 0/5] Add support for locked bridge ports (for 802.1X)

by Hans Schultz

This series starts by adding support for SA filtering to the bridge, which is then allowed to be offloaded to switchdev devices. Furthermore an offloading implementation is supplied for the mv88e6xxx driver. Public Local Area Networks are often deployed such that there is a risk of unauthorized or unattended clients getting access to the LAN. To prevent such access we introduce SA filtering, such that ports designated as secure ports are set in locked mode, so that only authorized source MAC addresses are given access by adding them to the bridges forwarding database. Incoming packets with source MAC addresses that are not in the forwarding database of the bridge are discarded. It is then the task of user space daemons to populate the bridge's forwarding database with static entries of authorized entities. The most common approach is to use the IEEE 802.1X protocol to take care of the authorization of allowed users to gain access by opening for the source address of the authorized host. With the current use of the bridge parameter in hostapd, there is a limitation in using this for IEEE 802.1X port authentication. It depends on hostapd attaching the port on which it has a successful authentication to the bridge, but that only allows for a single authentication per port. This patch set allows for the use of IEEE 802.1X port authentication in a more general network context with multiple 802.1X aware hosts behind a single port as depicted, which is a commonly used commercial use-case, as it is only the number of available entries in the forwarding database that limits the number of authenticated clients. +--------------------------------+ | | | Bridge/Authenticator | | | +-------------+------------------+ 802.1X port | | | +------+-------+ | | | Hub/Switch | | | +-+----------+-+ | | +--+--+ +--+--+ | | | | Hosts | a | | b | . . . | | | | +-----+ +-----+ The 802.1X standard involves three different components, a Supplicant (Host), an Authenticator (Network Access Point) and an Authentication Server which is typically a Radius server. This patch set thus enables the bridge module together with an authenticator application to serve as an Authenticator on designated ports. For the bridge to become an IEEE 802.1X Authenticator, a solution using hostapd with the bridge driver can be found at https://github.com/westermo/hostapd/tree/bridge_driver . The relevant components work transparently in relation to if it is the bridge module or the offloaded switchcore case that is in use.

[PATCH RESEND] kselftest: kvm/arm64: Skip tests if we can't create a vgic-v3

by Mark Brown

The arch_timer and vgic_irq kselftests assume that they can create a vgic-v3, using the library function vgic_v3_setup() which aborts with a test failure if it is not possible to do so. Since vgic-v3 can only be instantiated on systems where the host has GICv3 this leads to false positives on older systems where that is not the case. Fix this by changing vgic_v3_setup() to return an error if the vgic can't be instantiated and have the callers skip if this happens. We could also exit flagging a skip in vgic_v3_setup() but this would prevent future test cases conditionally deciding which GIC to use or generally doing more complex output.
