2018-08-30	Add seccomp filter to fsgofer	Fabricio Voznika

2018-08-27	runsc: fsgofer should return a unique QID.Path for each file.	Nicolas Lacasse
	Previously, we were only using the host inode id as the QID path. But the host filesystem can have multiple devices with conflicting inode ids. This resulted in duplicate inode ids in the sentry. This CL generates a unique QID for each <host inode, host device> pair. PiperOrigin-RevId: 210424813 Change-Id: I16d106f61c7c8f910c0da4ceec562a010ffca2fb
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
2018-08-24	Add option to panic gofer if writes are attempted over RO mounts	Fabricio Voznika
	This is used when '--overlay=true' to guarantee writes are not sent to gofer. PiperOrigin-RevId: 210116288 Change-Id: I7616008c4c0e8d3668e07a205207f46e2144bf30
2018-08-22	runsc: De-flakes container_test TestMultiContainerSanity.	Kevin Krakauer
	The bug was caused by os.File's finalizer, which closes the file. Because fsgofer.serve() was passed a file descriptor as an int rather than a os.File, callers would pass os.File.Fd(), and the os.File would go out of scope. Thus, the file would get GC'd and finalized nondeterministically, causing failures when the file was used. PiperOrigin-RevId: 209861834 Change-Id: Idf24d5c1f04c9b28659e62c97202ab3b4d72e994
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.

2018-07-30	Cleans up files created if there is a failure.	Brielle Broder
	PiperOrigin-RevId: 206674267 Change-Id: Ifc4eb19e0882e8bed566e9c553af910925fe6ae2
2018-06-04	Make fsgofer attach more strict	Fabricio Voznika
	Refuse to mount paths with "." and ".." in the path to prevent a compromised Sentry to mount "../../secrets". Only allow Attach to be called once per mount point. PiperOrigin-RevId: 199225929 Change-Id: I2a3eb7ea0b23f22eb8dde2e383e32563ec003bd5
2018-05-10	Fix failure to rename directory	Fabricio Voznika
	os.Rename validates that the target doesn't exist, which is different from syscall.Rename which replace the target if both are directories. fsgofer needs the syscall behavior. PiperOrigin-RevId: 196194630 Change-Id: I87d08cad88b5ef310b245cd91647c4f5194159d8
2018-05-10	Open file as read-write when mount points to a file	Fabricio Voznika
	This is to allow files mapped directly, like /etc/hosts, to be writable. Closes #40 PiperOrigin-RevId: 196155920 Change-Id: Id2027e421cef5f94a0951c3e18b398a77c285bbd
