2021-02-18Make socketops reflect correct sndbuf value for host UDS.Bhasker Hariharan
Also skips a test if the setsockopt to increase send buffer did not result in an increase. This is possible when the underlying socket is a host backed unix domain socket as in such cases gVisor does not permit increasing SO_SNDBUF. PiperOrigin-RevId: 358285158

2021-02-18Make b.N increase by KB not bytes on iperf.Zach Koopmans
Currently, iperf runs a client that scales by bytes sent. In practice, this causes b.N to scale slowly and have several short lived containers. Instead, scale by KB to more quickly reach required time. PiperOrigin-RevId: 358244926

2021-02-17Deflake tcp_network_unreachable testZeling Feng
Previously, we make two connect attempts. If the first attempt is still on going when the second attempt is made, the test will fail. This change deflakes the situation by not making the second attempt, instead, we poll for the first attempt's completion and read the errno from SO_ERROR. PiperOrigin-RevId: 358104769

2021-02-17Add gohacks.Slice/StringHeader.Jamie Liu
See https://github.com/golang/go/issues/19367 for rationale. Note that the upstream decision arrived at in that thread, while useful for some of our use cases, doesn't account for all of our SliceHeader use cases (we often use SliceHeader to extract pointers from slices in a way that avoids bounds checking and/or handles nil slices correctly) and also doesn't exist yet.

2021-02-17Check for directory emptiness in VFS1 overlay rmdir().Jamie Liu
Note that this CL reorders overlayEntry.copyMu before overlayEntry.dirCacheMu in the overlayFileOperations.IterateDir() => readdirEntries() path - but this lock ordering is already required by overlayRemove/Bind() => overlayEntry.markDirectoryDirty(), so this actually just fixes an inconsistency.

2021-02-17[infra] Split tcpip/integration test targets to aid investigation.Ayush Ranjan
tcpip integration tests have been flaky lately. They usually run in 20 seconds and have a 60 seconds timeout. Sometimes they timeout which could be due to a bug or deadlock. To further investigate it might be helpful to split the targets and see which test is causing the flake. Added a new tcpip/tests/utils package to hold all common utilities across all tests.

2021-02-17Deflake //test/iptables:iptables_testKevin Krakauer
We were opening dual-stack sockets, but tests only set iptables rules for a single network protocol. Thus, packets (probably sent by previous tests) could sneak in and break tests. Tested with: bazel test ///test/iptables:iptables_test --test_arg=--runtime=runsc --nocache_test_results --test_output=errors --runs_per_test=1000 --test_filter=TestFilterInputDropUDP PiperOrigin-RevId: 357972385

2021-02-11[netstack] Fix recovery entry and exit checks.Ayush Ranjan
Entry check: - Earlier implementation was preventing us from entering recovery even if SND.UNA is lost but dupAckCount is still below threshold. Fixed that. - We should only enter recovery when at least one more byte of data beyond the highest byte that was outstanding when fast retransmit was last entered is acked. Added that check. Exit check: - Earlier we were checking if SEG.ACK is in range [SND.UNA, SND.NXT]. The intention was to check if any unacknowledged data was ACKed. Note that (SEG.ACK - 1) is actually the sequence number which was ACKed. So we were incorrectly including (SND.UNA - 1) in the range. Fixed the check to now be (SEG.ACK - 1) in range [SND.UNA, SND.NXT). Additionally, moved a RACK specific test to the rack tests file. Added tests for the changes I made. PiperOrigin-RevId: 357091322
