2020-07-30Call lseek(0, SEEK_CUR) unconditionally in runsc fsgofer's Readdir(offset=0).Jamie Liu
9P2000.L is silent as to how readdir RPCs interact with directory mutation. The most performant option is for Treaddir with offset=0 to restart iteration, avoiding needing to walk+open+clunk a new directory fid between invocations of getdents64(2), and the VFS2 gofer client assumes this is the case. Make this actually true for the runsc fsgofer. Fixes #3344, #3345, #3355 PiperOrigin-RevId: 324090384

2020-07-30[runtime tests] go language test enhancementAyush Ranjan
- Unexported some passing tests. This will increase the testing surface and will be especially helpful when this is enabled for vfs2. - Run tool tests with -v (verbose output). We only print the output when a test fails so this should not clutter the output. - Run tool tests with "-no-rebuild" flag. - Surround test name with appropriate regex, i.e. ^testname$. This will ensure that only that test is run. Earlier running go_test:os would also run go_test:os/exec, go_test:os/signal, go_test:os/user. This should help speed up the tests as we do not run the same test multiple times anymore. - Updated bugs. Updates #3191 PiperOrigin-RevId: 324028878

2020-07-27Ask for *testing.T instead of storing itJay Zhuang
Storing *testing.T on test helper structs is problematic when subtests are used, because it is possible for nested tests to call Fatal on parent test, which incorrect terminates the parent test. For example func TestOuter(t *testing.T) { dut := NewDUT(t) t.Run("first test", func(t *testing.T) { dut.FallibleCall() }) t.Run("second test", func(t *testing.T) { dut.FallibleCall() } } In the example above, assuming `FallibleCall` calls `t.Fatal` on the `t` it holds, if `dut.FallibleCall` fails in "first test", it will call `Fatal` on the parent `t`, quitting `TestOuter`. This is not a behavior we want. PiperOrigin-RevId: 323350241
2020-07-26Add profiling to dockerutilZach Koopmans

2020-07-25test/syscall: run each test case in a separate network namespaceAndrei Vagin
... when it is possible. The guitar gVisorKernel*Workflow-s runs test with the local execution_method. In this case, blaze runs test cases locally without sandboxes. This means that all tests run in the same network namespace. We have a few tests which use hard-coded network ports and they can fail if one of these port will be used by someone else or by another test cases. PiperOrigin-RevId: 323137254
2020-07-24Bugfix: non-native tests were tagged as nativeKevin Krakauer

2020-07-24Speed up some iptables testsKevin Krakauer
Sending UDP packets in a loop can be done in a separate goroutine. We can't do this in ContainerAction because the container will terminate early. Locally, scripts/iptables_tests.sh runs ~40 seconds faster.

2020-07-22make connect(2) fail when dest is unreachableKevin Krakauer
Previously, ICMP destination unreachable datagrams were ignored by TCP endpoints. This caused connect to hang when an intermediate router couldn't find a route to the host. This manifested as a Kokoro error when Docker IPv6 was enabled. The Ruby image test would try to install the sinatra gem and hang indefinitely attempting to use an IPv6 address. Fixes #3079.
2020-07-22iptables: don't NAT existing connectionsKevin Krakauer
Fixes a NAT bug that manifested as: - A SYN was sent from gVisor to another host, unaffected by iptables. - The corresponding SYN/ACK was NATted by a PREROUTING REDIRECT rule despite being part of the existing connection. - The socket that sent the SYN never received the SYN/ACK and thus a connection could not be established. We handle this (as Linux does) by tracking all connections, inserting a no-op conntrack rule for new connections with no rules of their own. Needed for istio support (#170).
