2021-04-28Remove side effect from test casesFabricio Voznika
Restore capabilities for tests that need to change them. PiperOrigin-RevId: 371007047
2021-04-13Remove _NoRandomSave tests.Adin Scannell
We do not currently run random save tests. PiperOrigin-RevId: 368309921
2021-01-30Remove side effect from open testsFabricio Voznika
Individual test cases must not rely on being executed in a clean environment. PiperOrigin-RevId: 354730126
2021-01-28Add O_PATH support in vfs2gVisor bot
PiperOrigin-RevId: 354367665
2020-12-30Add test for open(2) with O_WRONLY|O_RDWR.Dean Deng

2020-08-17[vfs] Do O_DIRECTORY check after resolving symlinks.Ayush Ranjan
Fixes python runtime test test_glob. Updates #3515 We were checking is the to-be-opened dentry is a dir or not before resolving symlinks. We should check that after resolving symlinks. This was preventing us from opening a symlink which pointed to a directory with O_DIRECTORY. Also added this check in tmpfs and removed a duplicate check. PiperOrigin-RevId: 327085895
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
2020-08-12[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
2020-07-22Add O_APPEND support in vfs2 gofer.Ayush Ranjan
Helps in fixing open syscall tests: AppendConcurrentWrite and AppendOnly. We also now update the file size for seekable special files (regular files) which we were not doing earlier. Updates #2923 PiperOrigin-RevId: 322670843
2020-06-22Check for invalid trailing / when traversing path in gofer OpenAt.Dean Deng
Updates #2923. PiperOrigin-RevId: 317700049
2020-06-03Add test for O_TRUNCZach Koopmans
b/36576592 calls out an edge case previously not supported by HostFS. HostFS is currently being removed, meaning gVisor supports this feature. Simply add the test to open_test. PiperOrigin-RevId: 314610226
2020-04-07Make gofer.dentry.destroyLocked idempotentFabricio Voznika
gofer operations accumulate dentries touched in a slice to call checkCachingLocked on them when the operation is over. In case the same dentry is touched multiple times during the operation, checkCachingLocked, and consequently destroyLocked, may be called more than once for the same dentry. Updates #1198 PiperOrigin-RevId: 305276819

2019-11-14Check that a file is a regular file with open(O_TRUNC).Kevin Krakauer
It was possible to panic the sentry by opening a cache revalidating folder with O_TRUNC|O_CREAT. Avoids breaking php tests. PiperOrigin-RevId: 280533213
2019-08-30Add C++ toolchain and fix compile issues.Adin Scannell
This was accidentally introduced in 31f05d5d4f62c4cd4fe3b95b333d0130aae4b2c1. Fixes #788. PiperOrigin-RevId: 266462843
2019-06-24fs: synchronize concurrent writes into files with O_APPENDAndrei Vagin
For files with O_APPEND, a file write operation gets a file size and uses it as offset to call an inode write operation. This means that all other operations which can change a file size should be blocked while the write operation doesn't complete. PiperOrigin-RevId: 254873771

2019-03-05Add NoRandomSave to tests with correctness DisableSaveMichael Pratt
Tests using DisableSave because a portion of the test is *incompatible* with S/R clearly cannot use random S/R, as the saves may occur in the DisableSave critical section. Most such tests already have NoRandomSave. Add it to the rest. PiperOrigin-RevId: 236914708 Change-Id: Iee1cf044cfa7cb8d5aba21ddc130926218210c48
