2021-11-02Allow SetAttr and Allocate for deleted filesFabricio Voznika
It's safe to call SetAttr and Allocate on fsgofer because the file path is not used to open the file, if needed. Fixes #3654 PiperOrigin-RevId: 407149393
2021-04-02Implement cgroupfs.Rahat Mahmood
A skeleton implementation of cgroupfs. It supports trivial cpu and memory controllers with no support for hierarchies. PiperOrigin-RevId: 366561126
2021-01-28Add O_PATH support in vfs2gVisor bot
PiperOrigin-RevId: 354367665
2020-09-10[vfs] Disable nlink tests for overlayfs.Ayush Ranjan
Overlayfs intentionally does not compute nlink for directories (because it can be really expensive). Linux returns 1, VFS2 returns 2 and VFS1 actually calculates the correct value. PiperOrigin-RevId: 330967139
2020-08-31Remove __fuchsia__ definesTamir Duberstein
These mostly guard linux-only headers; check for linux instead. PiperOrigin-RevId: 329362762
2020-08-26tmpfs: Allow xattrs in the trusted namespace if creds has CAP_SYS_ADMIN.Nicolas Lacasse
This is needed to support the overlay opaque attribute. PiperOrigin-RevId: 328552985
2020-07-07Deflake exec test.Jamie Liu
- Only use MAXSYMLINKS/2+1 symlinks for each of the interpreter and script paths in SymlinkLimitRefreshedForInterpreter to tolerate cases where the original paths (/tmp, /bin, or /bin/echo) themselves contain symlinks. - Ensure that UnshareFiles performs execve immediately after clone(CLONE_VFORK) (no heap allocation for ExecveArray/RunfilesPath). - Use lstat() rather than stat() for the existence check in fs_util's Exists; the latter will fail if the symlink target does not exist, even if the symlink does.

2019-10-18test/perf: optimize the getdents testAndrei Vagin
* Use mknod instead of open&close to create an empty file. * Limit a number of files to (1<<16) instead of 100K. In this case, a test set is (1, 8, 64, 512, 4K, 32K, 64K) instead of (1, 8, 64, 512, 4K, 32K, 98K). I think it is easier to compare results for 32K and 64K than 32K and 98K. And results for 98K doesn't give us more information than for 54K. PiperOrigin-RevId: 275552507
