component	task	assignee	comments
crtools	support one of MPI implementations	-	worth starting with OpenMPI
crtools	generate task's core file out of images	-	-
crtools	restore in namespace	-	having images taken from live app, need to restore them inside newly created namespace. For PID we'd have to provide our own init, for NET -- setup some veth.
crtools	TCP socket migration with changed IP	xemul@	it might make sense to migrate a tcp connection on a box with changed IP address _if_ both boxes are NAT-ed to the destination. We will then have to go to NAT box and fix the conntracks, but this might make sense.
crtools	Applying images	xemul@	Think about ability to take images and apply them to a living task(s). E.g. -- repopulate fdtable according to data from image. Another use-case -- when doing partial migration we'll need to modify one part to switch from pipes to sockets
crtools	Modify restored resources run-time	xemul@	Need (probably) some way to alter what is being restored. Usage example -- change the IP address of sockets from task above.
crtools	partial migration	-	migrate some tasks while proxying IPC to existing others (pipes->sockets, etc.)
crtools	Shared objects (mm/fs) support	avagin@	Now we have the kcmp syscall and can do it. The first candidate is mm sharing, as we do know, that MySQL does so sometimes.
kernel	Provide own defconfig	gorcunov@	suggested by avagin@
crtools	Paranoid dumping and restoring	-	Make paranoid checks for what we dump. E.g. pgid being valid (withing session) and fds drained from parasite are valid
crtools	Smart paths resolution	-	Need a way to resolve paths to overmounted files. There are two ways: 1. Move mounts, that overlap the desired path temprarily. 2. When creating a new mount pre-open an fd keeping the mountpoint. Later, do accurate path resolve and call openat() on proper mountpoint fd
kernel/crtools	TCP repair fixes	-	TCP repair TODO
crtools	Multiple namespaces	-	Need to handle the cases when more than one namespace of one type exists and dump them properly
vzkernel/crtools	OpenVZ kernel support	avagin@	Within 3.5 and RHEL7 port (All patches before 3.8 are here already)
crtools	More sockoptions	xemul@	SOL_ are done
crtools	Bridges in container	-
crtools	cgroups in container	-
crtools/kernel	NFS	-
crtools	migrate script	-	It's not complex, but openvz-like migrate scripts should exists
crtools	Validate .img files	-	For a given set of image files check, that they are in "restorable" shape
crtools	Restore a process tree	Larisa Markeeva	Need to restore any process tree, which could be created with help PR_SET_CHILD_SUBREAPER and CLONE_PARENT. Processes can share other resources clone(2). Look at session02
crtools	C API (.so)	-
crtools	X app	-	Dump/restore of graphical applications
kernel	RKU	vdavydov@	Rebootless Kernel Update
crtools	merge snapshots	Pavel Tikhomirov	-
kernel	undo semaphores	Cyrill Gorcunov	Require mods from both sides -- criu and kernel
