2020-01-06fcnal-test: Fix vrf argument in local tcp testsDavid Ahern1-4/+4
The recent MD5 tests added duplicate configuration in the default VRF. This change exposed a bug in existing tests designed to verify no connection when client and server are not in the same domain. The server should be running bound to the vrf device with the client run in the default VRF (the -2 option is meant for validating connection data). Fix the option for both tests. While technically this is a bug in previous releases, the tests are properly failing since the default VRF does not have any routing configuration so there really is no need to backport to prior releases.

2019-12-18selftests: forwarding: sch_ets: Add test coverage for ETS QdiscPetr Machata3-0/+571
This tests the newly-added ETS Qdisc. It runs two to three streams of traffic, each with a different priority. ETS Qdisc is supposed to allocate bandwidth according to the DRR algorithm and given weights. After running the traffic for a while, counters are compared for each stream to check that the expected ratio is in fact observed. In order for the DRR process to kick in, a traffic bottleneck must exist in the first place. In slow path, such bottleneck can be implemented by wrapping the ETS Qdisc inside a TBF or other shaper. This might however make the configuration unoffloadable. Instead, on HW datapath, the bottleneck would be set up by lowering port speed and configuring shared buffer suitably. Therefore the test is structured as a core component that implements the testing, with two wrapper scripts that implement the details of slow path resp. fast path configuration.

2019-12-14selftests/net: make so_txtime more robust to timer varianceWillem de Bruijn2-5/+88
The SO_TXTIME test depends on accurate timers. In some virtualized environments the test has been reported to be flaky. This is easily reproduced by disabling kvm acceleration in Qemu. Allow greater variance in a run and retry to further reduce flakiness. Observed errors are one of two kinds: either the packet arrives too early or late at recv(), or it was dropped in the qdisc itself and the recv() call times out. In the latter case, the qdisc queues a notification to the error queue of the send socket. Also explicitly report this cause.

Some versions of iproute2 will output more than one line per entry, which will cause the test to fail, like: TEST: ipv6: list and flush cached exceptions [FAIL] can't list cached exceptions That happens, for example, with iproute2 4.15.0. When using the -oneline option, this will work just fine: TEST: ipv6: list and flush cached exceptions [ OK ] This also works just fine with a more recent version of iproute2, like 5.4.0. For some reason, two lines are printed for the IPv4 test no matter what version of iproute2 is used. Use the same -oneline parameter there instead of counting the lines twice.

2019-11-16selftests: net: avoid ptl lock contention in tcp_mmapEric Dumazet1-5/+53
tcp_mmap is used as a reference program for TCP rx zerocopy, so it is important to point out some potential issues. If multiple threads are concurrently using getsockopt(... TCP_ZEROCOPY_RECEIVE), there is a chance the low-level mm functions compete on shared ptl lock, if vma are arbitrary placed. Instead of letting the mm layer place the chunks back to back, this patch enforces an alignment so that each thread uses a different ptl lock. Performance measured on a 100 Gbit NIC, with 8 tcp_mmap clients launched at the same time : $ for f in {1..8}; do ./tcp_mmap -H 2002:a05:6608:290:: & done In the following run, we reproduce the old behavior by requesting no alignment : $ tcp_mmap -sz -C $((128*1024)) -a 4096 received 32768 MB (100 % mmap'ed) in 9.69532 s, 28.3516 Gbit cpu usage user:0.08634 sys:3.86258, 120.511 usec per MB, 171839 c-switches received 32768 MB (100 % mmap'ed) in 25.4719 s, 10.7914 Gbit cpu usage user:0.055268 sys:21.5633, 659.745 usec per MB, 9065 c-switches received 32768 MB (100 % mmap'ed) in 28.5419 s, 9.63069 Gbit cpu usage user:0.057401 sys:23.8761, 730.392 usec per MB, 14987 c-switches received 32768 MB (100 % mmap'ed) in 28.655 s, 9.59268 Gbit cpu usage user:0.059689 sys:23.8087, 728.406 usec per MB, 18509 c-switches received 32768 MB (100 % mmap'ed) in 28.7808 s, 9.55074 Gbit cpu usage user:0.066042 sys:23.4632, 718.056 usec per MB, 24702 c-switches received 32768 MB (100 % mmap'ed) in 28.8259 s, 9.5358 Gbit cpu usage user:0.056547 sys:23.6628, 723.858 usec per MB, 23518 c-switches received 32768 MB (100 % mmap'ed) in 28.8808 s, 9.51767 Gbit cpu usage user:0.059357 sys:23.8515, 729.703 usec per MB, 14691 c-switches received 32768 MB (100 % mmap'ed) in 28.8879 s, 9.51534 Gbit cpu usage user:0.047115 sys:23.7349, 725.769 usec per MB, 21773 c-switches New behavior (automatic alignment based on Hugepagesize), we can see the system overhead being dramatically reduced. $ tcp_mmap -sz -C $((128*1024)) received 32768 MB (100 % mmap'ed) in 13.5339 s, 20.3103 Gbit cpu usage user:0.122644 sys:3.4125, 107.884 usec per MB, 168567 c-switches received 32768 MB (100 % mmap'ed) in 16.0335 s, 17.1439 Gbit cpu usage user:0.132428 sys:3.55752, 112.608 usec per MB, 188557 c-switches received 32768 MB (100 % mmap'ed) in 17.5506 s, 15.6621 Gbit cpu usage user:0.155405 sys:3.24889, 103.891 usec per MB, 226652 c-switches received 32768 MB (100 % mmap'ed) in 19.1924 s, 14.3222 Gbit cpu usage user:0.135352 sys:3.35583, 106.542 usec per MB, 207404 c-switches received 32768 MB (100 % mmap'ed) in 22.3649 s, 12.2906 Gbit cpu usage user:0.142429 sys:3.53187, 112.131 usec per MB, 250225 c-switches received 32768 MB (100 % mmap'ed) in 22.5336 s, 12.1986 Gbit cpu usage user:0.140654 sys:3.61971, 114.757 usec per MB, 253754 c-switches received 32768 MB (100 % mmap'ed) in 22.5483 s, 12.1906 Gbit cpu usage user:0.134035 sys:3.55952, 112.718 usec per MB, 252997 c-switches received 32768 MB (100 % mmap'ed) in 22.6442 s, 12.139 Gbit cpu usage user:0.126173 sys:3.71251, 117.147 usec per MB, 253728 c-switches Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Soheil Hassas Yeganeh <soheil@google.com> Cc: Arjun Roy <arjunroy@google.com> Acked-by: Soheil Hassas Yeganeh <soheil@google.com> Signed-off-by: David S.

2019-11-07selftests: devlink: Export functions to devlink libraryAmit Cohen1-0/+42
l2_drops_test() is used to check that drop traps are functioning as intended. Currently it is only used in the layer 2 test, but it is also useful for the layer 3 test introduced in the subsequent patch. l2_drops_cleanup() is used to clean configurations and kill mausezahn proccess. Export the functions to the common devlink library to allow it to be re-used by future tests.

Fix printf format warnings on arm (and other 32bit arch). - udpgso.c and udpgso_bench_tx use %lu for size_t but it should be unsigned long long on 32bit arch. - so_txtime.c uses %ld for int64_t, but it should be unsigned long long on 32bit arch.

2019-11-07selftests: net: Use size_t and ssize_t for counting file sizeMasami Hiramatsu1-4/+4
Use size_t and ssize_t correctly for counting send file size instead of unsigned long and long, because long is 32bit on 32bit arch, which is not enough for counting long file size (>4GB).

2019-10-03udp: only do GSO if # of segs > 1Josh Hunt1-12/+4
Prior to this change an application sending <= 1MSS worth of data and enabling UDP GSO would fail if the system had SW GSO enabled, but the same send would succeed if HW GSO offload is enabled. In addition to this inconsistency the error in the SW GSO case does not get back to the application if sending out of a real device so the user is unaware of this failure. With this change we only perform GSO if the # of segments is > 1 even if the application has enabled segmentation. I've also updated the relevant udpgso selftests.

2019-09-26ipv6: do not free rt if FIB_LOOKUP_NOREF is set on suppress ruleJason A. Donenfeld1-1/+16
Commit 7d9e5f422150 removed references from certain dsts, but accounting for this never translated down into the fib6 suppression code. This bug was triggered by WireGuard users who use wg-quick(8), which uses the "suppress-prefix" directive to ip-rule(8) for routing all of their internet traffic without routing loops. The test case added here causes the reference underflow by causing packets to evaluate a suppress rule.
