2020-07-23	Fix fsgofer Open() when control file is using O_PATH	Fabricio Voznika
	Open tries to reuse the control file to save syscalls and file descriptors when opening a file. However, when the control file was opened using O_PATH (e.g. no file permission to open readonly), Open() would not check for it. PiperOrigin-RevId: 322821729
2020-05-28	Move Cleanup to its own package	Fabricio Voznika

2020-01-09	New 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
2019-10-30	Enable runsc/fsgofer support on arm64.	Haibo Xu
	newfstatat() syscall is not supported on arm64, so we resort to use the fstatat() syscall. Signed-off-by: Haibo Xu <haibo.xu@arm.com> Change-Id: I9e89d46c5ec9ae07db201c9da5b6dda9bfd2eaf0
2019-06-13	Update canonical repository.	Adin Scannell

2019-01-31	Remove license comments	Michael Pratt
	Nothing reads them and they can simply get stale. Generated with: $ sed -i "s/licenses($.$)./licenses(\1)/" **/BUILD PiperOrigin-RevId: 231818945 Change-Id: Ibc3f9838546b7e94f13f217060d31f4ada9d4bf0
2019-01-07	Undo changes in case of failure to create file/dir/symlink	Fabricio Voznika
	File/dir/symlink creation is multi-step and may leave state behind in case of failure in one of the steps. Added best effort attempt to clean up. PiperOrigin-RevId: 228286612 Change-Id: Ib03c27cd3d3e4f44d0352edc6ee212a53412d7f1
2018-10-31	Make lazy open the mode of operation for fsgofer	Fabricio Voznika
	With recent changes to 9P server, path walks are now safe inside open, create, rename and setattr calls. To simplify the code, remove the lazyopen=false mode that was used for bind mounts, and converge all mounts to using lazy open.

2018-10-23	Track paths and provide a rename hook.	Adin Scannell
	This change also adds extensive testing to the p9 package via mocks. The sanity checks and type checks are moved from the gofer into the core package, where they can be more easily validated. PiperOrigin-RevId: 218296768 Change-Id: I4fc3c326e7bf1e0e140a454cbacbcc6fd617ab55
2018-08-27	Put fsgofer inside chroot	Fabricio Voznika
	Now each container gets its own dedicated gofer that is chroot'd to the rootfs path. This is done to add an extra layer of security in case the gofer gets compromised. PiperOrigin-RevId: 210396476 Change-Id: Iba21360a59dfe90875d61000db103f8609157ca0
2018-08-15	runsc fsgofer: Support dynamic serving of filesystems.	Kevin Krakauer
	When multiple containers run inside a sentry, each container has its own root filesystem and set of mounts. Containers are also added after sentry boot rather than all configured and known at boot time. The fsgofer needs to be able to serve the root filesystem of each container. Thus, it must be possible to add filesystems after the fsgofer has already started. This change: * Creates a URPC endpoint within the gofer process that listens for requests to serve new content. * Enables the sentry, when starting a new container, to add the new container's filesystem. * Mounts those new filesystems at separate roots within the sentry.
