2020-08-03Add support for a reverse HTTPD test.Bhasker Hariharan
This change adds a new reverse HTTP test where the HTTPD server runs in a native container but the client runs inside gVisor. It allows us to test download performance under varying levels of concurrency. Also tweaks the concurrent request numbers to test for high levels of concurrency. PiperOrigin-RevId: 324651203
2020-07-31Fix MountFuseFilesystem tests failingCraig Chi
Before kernel version 4.16-rc6, fuse mount is protected by capable(CAP_SYS_ADMIN). After this version, it uses ns_capable(CAP_SYS_ADMIN) to protect. Before the 4.16 kernel, it was not allowed to mount fuse file systems without the global CAP_SYS_ADMIN. Fixes #3360
2020-07-31test/socket_netlink_route: check that there is a route on local or main tablesAndrei Vagin
A new network namespace has only the local route table. PiperOrigin-RevId: 324303629
2020-07-31[runtime tests] Enhance java runtime test.Ayush Ranjan
- Added a bunch of helpful options which help in speeding up the test and providing useful output. - Unexcluded passing tests and updated bugs. Excluded tests which were failing. - Increased the batch size for java tests so that we can take advantage of the shared JVMs. The running time of the tests decreased from 3+ hours (I don't know the exact running time because this test has always timed out after 3 hours) to 1 hour 15 minutes. We can reliably run this a CI kokoro job. PiperOrigin-RevId: 324301503

Envoy (#170) uses this to get the original destination of redirected packets.
2020-07-30Port nginx and move parsers to own package.Zach Koopmans
This change: - Ports the nginx benchmark. - Switches the Httpd benchmark to use 'hey' as a client. - Moves all parsers to their own package 'tools'. Parsers are moved to their own package because 1) parsing output of a command is often dependent on the format of the command (e.g. 'fio --json'), 2) to enable easier reuse, and 3) clean up and simplify actual running benchmarks (no TestParser functions and ugly sample output in benchmark files).

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

Return on success should be 0, not size of the struct copied out. PiperOrigin-RevId: 324029193
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
Adds profiling with `runsc debug` or pprof to dockerutil. All targets using dockerutil should now be able to use profiling. In addition, modifies existing benchmarks to use profiling. PiperOrigin-RevId: 323298634
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
Copy the list of tags when passing it to _syscall_test.
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).
2020-07-22Add O_APPEND support in vfs2 gofer.Ayush Ranjan
