gvisor - Container Runtime Sandbox

2020-01-27	Update 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
2019-11-20	Pass OpenTruncate to gofer in Open call when opening file with O_TRUNC.	Nicolas Lacasse
	Note that the Sentry still calls Truncate() on the file before calling Open. A new p9 version check was added to ensure that the p9 server can handle the the OpenTruncate flag. If not, then the flag is stripped before sending. PiperOrigin-RevId: 281609112
2019-10-16	Fix problem with open FD when copy up is triggered in overlayfs	Fabricio Voznika
	Linux kernel before 4.19 doesn't implement a feature that updates open FD after a file is open for write (and is copied to the upper layer). Already open FD will continue to read the old file content until they are reopened. This is especially problematic for gVisor because it caches open files. Flag was added to force readonly files to be reopenned when the same file is open for write. This is only needed if using kernels prior to 4.19. Closes #1006 It's difficult to really test this because we never run on tests on older kernels. I'm adding a test in GKE which uses kernels with the overlayfs problem for 1.14 and lower.

2019-03-28	Clean up gofer handle caching.	Jamie Liu
	- Document fsutil.CachedFileObject.FD() requirements on access permissions, and change gofer.inodeFileState.FD() to honor them. Fixes #147. - Combine gofer.inodeFileState.readonly and gofer.inodeFileState.readthrough, and simplify handle caching logic. - Inline gofer.cachePolicy.cacheHandles into gofer.inodeFileState.setSharedHandles, because users with access to gofer.inodeFileState don't necessarily have access to the fs.Inode (predictably, this is a save/restore problem).
