2020-01-31Implement file locks for regular tmpfs files in VFSv2.Dean Deng
Add a file lock implementation that can be embedded into various filesystem implementations. Updates #1480 PiperOrigin-RevId: 292614758
2020-01-27Update package locations.Adin Scannell
Because the abi will depend on the core types for marshalling (usermem, context, safemem, safecopy), these need to be flattened from the sentry directory. These packages contain no sentry-specific details. PiperOrigin-RevId: 291811289
2020-01-22Move VFS2 handling of FD readability/writability to vfs.FileDescription.Jamie Liu
PiperOrigin-RevId: 291006713
2020-01-16Implement tmpfs.SetStat with a size argument.Nicolas Lacasse
This is similar to 'Truncate' in vfs1. Updates https://github.com/google/gvisor/issues/1197 PiperOrigin-RevId: 290139140
2020-01-09New sync package.Ian Gudger
* Rename syncutil to sync. * Add aliases to sync types. * Replace existing usage of standard library sync package. This will make it easier to swap out synchronization primitives. For example, this will allow us to use primitives from github.com/sasha-s/go-deadlock to check for lock ordering violations. Updates #1472 PiperOrigin-RevId: 289033387
2020-01-06Convert memfs into proto-tmpfs.Nicolas Lacasse
- Renamed memfs to tmpfs. - Copied fileRangeSet bits from fs/fsutil/ to fsimpl/tmpfs/ - Changed tmpfs to be backed by filemem instead of byte slice. - regularFileReadWriter uses a sync.Pool, similar to gofer client. PiperOrigin-RevId: 288356380
