2024-02-02selftests: net: fix tcp listener handling in pmtu.shPaolo Abeni
The pmtu.sh test uses a few TCP listener in a problematic way: It hard-codes a constant timeout to wait for the listener starting-up in background. That introduces unneeded latency and on very slow and busy host it can fail. Additionally the test starts again the same listener in the same namespace on the same port, just after the previous connection completed. Fast host can attempt starting the new server before the old one really closed the socket. Address the issues using the wait_local_port_listen helper and explicitly waiting for the background listener process exit.

2024-02-02selftests: net: cut more slack for gro fwd tests.Paolo Abeni
The udpgro_fwd.sh self-tests are somewhat unstable. There are a few timing constraints the we struggle to meet on very slow environments. Instead of skipping the whole tests in such envs, increase the test resilience WRT very slow hosts: increase the inter-packets timeouts, avoid resetting the counters every second and finally disable reduce the background traffic noise.

2024-02-02selftests/landlock: Fix capability for net_testMickaël Salaün
CAP_NET_ADMIN allows to configure network interfaces, not CAP_SYS_ADMIN which only allows to call unshare(2). Without this change, running network tests as a non-root user but with all capabilities would fail at the setup_loopback() step with "RTNETLINK answers: Operation not permitted". The issue is only visible when running tests with non-root users (i.e. only relying on ambient capabilities). Indeed, when configuring the network interface, the "ip" command is called, which may lead to the special handling of capabilities for the root user by execve(2). If root is the caller, then the inherited, permitted and effective capabilities are all reset, which then includes CAP_NET_ADMIN. However, if a non-root user is the caller, then ambient capabilities are masked by the inherited ones, which were explicitly dropped. To make execution deterministic whatever users are running the tests, set the noroot secure bit for each test, and set the inheritable and ambient capabilities to CAP_NET_ADMIN, the only capability that may be required after an execve(2). Factor out _effective_cap() into _change_cap(), and use it to manage ambient capabilities with the new set_ambient_cap() and clear_ambient_cap() helpers.

Since the "Fixes" commits mentioned below, the newly added "userspace pm" subtests of mptcp_join selftests are launching the whole transfer in the background, do the required checks, then wait for the end of transfer. There is no need to wait longer, especially because the checks at the end of the transfer are ignored (which is fine). This saves quite a few seconds on slow environments.

This selftest checks if the aggregated bandwidth is (almost) fully used as expected.

2024-02-01selftests: mptcp: increase timeout to 30 minMatthieu Baerts (NGI0)
On very slow environments -- e.g. when QEmu is used without KVM --, mptcp_join.sh selftest can take a bit more than 20 minutes. Bump the default timeout by 50% as it seems normal to take that long on some environments. When a debug kernel config is used, this selftest will take even longer, but that's certainly not a common test env to consider for the timeout. The Fixes tag that has been picked here is there simply to help having this patch backported to older stable versions. It is difficult to point to the exact commit that made some env reaching the timeout from time to time.

2024-02-01selftests: bonding: Check initial stateBenjamin Poirier
The purpose of the test_LAG_cleanup() function is to check that some hardware addresses are removed from underlying devices after they have been unenslaved. The test function simply checks that those addresses are not present at the end. However, if the addresses were never added to begin with due to some error in device setup, the test function currently passes. This is a false positive since in that situation the test did not actually exercise the intended functionality. Add a check that the expected addresses are indeed present after device setup. This makes the test function more robust. I noticed this problem when running the team/dev_addr_lists.sh test on a system without support for dummy and ipv6: tools/testing/selftests/drivers/net/team# ./dev_addr_lists.sh Error: Unknown device type.

2024-01-31tools/net/ynl: Add support for nested structsDonald Hunter
Make it possible for struct definitions to reference other struct definitions ofr binary members. For example, the tbf qdisc uses this struct definition for its parms attribute: - name: tc-tbf-qopt type: struct members: - name: rate type: binary struct: tc-ratespec - name: peakrate type: binary struct: tc-ratespec - name: limit type: u32 - name: buffer type: u32 - name: mtu type: u32 This adds the necessary schema changes and adds nested struct encoding and decoding to ynl.

2024-01-31selftests/net: Rectify key counters checksDmitry Safonov
As the names of (struct test_key) members didn't reflect whether the key was used for TX or RX, the verification for the counters was done incorrectly for asymmetrical selftests. Rename these with _tx appendix and fix checks in verify_counters(). While at it, as the checks are now correct, introduce skip_counters_checks, which is intended for tests where it's expected that a key that was set with setsockopt(sk, IPPROTO_TCP, TCP_AO_INFO, ...) might had no chance of getting used on the wire. Fixes the following failures, exposed by the previous commit: > not ok 51 server: Check current != rnext keys set before connect(): Counter pkt_good was expected to increase 0 => 0 for key 132:5 > not ok 52 server: Check current != rnext keys set before connect(): Counter pkt_good was not expected to increase 0 => 21 for key 137:10 > > not ok 63 server: Check current flapping back on peer's RnextKey request: Counter pkt_good was expected to increase 0 => 0 for key 132:5 > not ok 64 server: Check current flapping back on peer's RnextKey request: Counter pkt_good was not expected to increase 0 => 40 for key 137:10 Cc: Mohammad Nassiri <mnassiri@ciena.com> Fixes: 3c3ead555648 ("selftests/net: Add TCP-AO key-management test") Signed-off-by: Dmitry Safonov <dima@arista.com> Link: https://lore.kernel.org/r/20240130-tcp-ao-test-key-mgmt-v2-2-d190430a6c60@arista.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2024-01-31selftests/net: Argument value mismatch when calling verify_counters()Mohammad Nassiri
The end_server() function only operates in the server thread and always takes an accept socket instead of a listen socket as its input argument. To align with this, invert the boolean values used when calling verify_counters() within the end_server() function. As a result of this typo, the test didn't correctly check for the non-symmetrical scenario, where i.e. peer-A uses a key <100:200> to send data, but peer-B uses another key <105:205> to send its data. So, in simple words, different keys for TX and RX.

The test sends packets and compares enqueue, transmit and Ack timestamps with expected values. It installs netem delays to increase latency between these points. The test proves flaky in virtual environment (vng). Increase the delays to reduce variance. Scale measurement tolerance accordingly. Time sensitive tests are difficult to calibrate. Increasing delays 10x also increases runtime 10x, for one. And it may still prove flaky at some rate.

2024-01-31selftests: forwarding: Remove duplicated lib.sh contentPetr Machata
commit 25ae948b4478 ("selftests/net: add lib.sh") added net/lib.sh to contain code shared by tests under net/ and net/forwarding/. However, this caused issues with selftests from directories other than net/forwarding/, in particular those under drivers/net/. Those issues were avoided in a simple way by duplicating some content in commit 2114e83381d3 ("selftests: forwarding: Avoid failures to source net/lib.sh"). In order to remove the duplicated content, restore the inclusion of net/lib.sh from net/forwarding/lib.sh but with the following changes: * net/lib.sh is imported through the net_forwarding_dir path The original expression "source ../lib.sh" would look for lib.sh in the directory above the script file's one, which did not work for tests under drivers/net/. * net/lib.sh is added to TEST_INCLUDES Since net/forwarding/lib.sh now sources net/lib.sh, both of those files must be exported along with tests which source net/forwarding/lib.sh.
