2020-08-13[vfs2][gofer] Fix file creation flags sent to gofer.Ayush Ranjan
Fixes php runtime test ext/standard/tests/file/readfile_basic.phpt Fixes #3516 fsgofers only want the access mode in the OpenFlags passed to Create(). If more flags are supplied (like O_APPEND in this case), read/write from that fd will fail with EBADF. See runsc/fsgofer/fsgofer.go:WriteAt() VFS2 was providing more than just access modes. So filtering the flags using p9.OpenFlagsModeMask == linux.O_ACCMODE fixes the issue. Gofer in VFS1 also only extracts the access mode flags while making the create RPC. See pkg/sentry/fs/gofer/path.go:Create() Even in VFS2, when we open a handle, we extract out only the access mode flags + O_TRUNC. See third_party/gvisor/pkg/sentry/fsimpl/gofer/handle.go:openHandle() Added a test for this. PiperOrigin-RevId: 326574829

2020-08-13Ensure TCP TIME-WAIT is not terminated prematurely.Bhasker Hariharan
Netstack's TIME-WAIT state for a TCP socket could be terminated prematurely if the socket entered TIME-WAIT using shutdown(..., SHUT_RDWR) and then was closed using close(). This fixes that bug and updates the tests to verify that Netstack correctly honors TIME-WAIT under such conditions. Fixes #3106 PiperOrigin-RevId: 326456443
2020-08-12[vfs2][gofer] Return appropriate errors when opening and creating files.Ayush Ranjan
Fixes php test ext/standard/tests/file/touch_variation5.phpt on vfs2. Updates #3516 Also spotted a bug with O_EXCL, where we did not return EEXIST when we tried to open the root of the filesystem with O_EXCL | O_CREAT. Added some more tests for open() corner cases. PiperOrigin-RevId: 326346863

2020-08-12Limit the scope when deleting test log directory on successFabricio Voznika
The code was deleting logs for all tests when a single test passed. Change it to delete only the logs relevant to the test at hand. Also fixed the benchmark lookup code, which was always generating a single empty benchmark entry if there were not benchmarks. PiperOrigin-RevId: 326311477
2020-08-11Mark integration tests as passing in VFS2 except CheckpointRestore.Zach Koopmans
Mark all tests passing for VFS2 in: image_test integration_test There's no way to do negative look ahead/behind in golang test regex, so check if the tests uses VFS2 and skip CheckPointRestore if it does. PiperOrigin-RevId: 326050915
2020-08-10Implement FUSE_GETATTRCraig Chi
FUSE_GETATTR is called when a stat(2), fstat(2), or lstat(2) is issued from VFS2 layer to a FUSE filesystem. Fixes #3175

2020-08-06[runtime tests] Exclude failing python and java testsAyush Ranjan
test_httplib was un-excluded in cl/325137657. Exclude it again. test_httplib fails consistently when running in a kokoro job. Could not repro with Docker. There are some java tests that pass locally on Docker but fail when running within a kokoro job. Also make shard count a multiple of 8 to minimize idle cores and minimize test time.

2020-08-04Fix FUSE integration test failed with ECONNREFUSEDCraig Chi
The newer version of FUSE_INIT checks the response from the FUSE server if its major number is equal to 7. If it's not, then FUSE_INIT fails and further filesystem operations will get ECONNREFUSED. To mitigate this issue, we can send back a response with major version equals to 7 when consuming the first FUSE_INIT request. Fixes #3500

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

2020-07-31[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

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
