component	task	assignee	comments
crtools	support OFD posix locks	-
crtools	optimize kcmp calls	-	For fs/fdt/vm/etc we can pre-generate ID based on objects that live on them. If pre-ID matches, then call kcmp.
crtools	Shmem changes tracking	-
crtools	Page transfer filters	Ruslan Kuprieiev	Packing or encrypting the data would be nice
crtools	FUSE	-
crtools	32-bit tasks	Cyrill
crtools	Support one of MPI implementations	Adrian Reber	worth starting with OpenMPI
crtools	Generate task's core file out of images	-	-
crtools	Convert images to JSON and back	-	-
crtools	Modify restored resources run-time	-	Need (probably) some way to alter what is being restored. Usage example -- change the IP address of sockets from task above.
crtools	TCP socket migration with changed IP	-	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@ w/ students	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	Partial migration	-	migrate some tasks while proxying IPC to existing others (pipes->sockets, etc.)
crtools	Shared objects (mm/fs) support	-	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.
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	Bridges in container	-
crtools	VLANs in containers	-
crtools	PPP support	-
crtools/kernel	DelayFS for NFS/Fuse migration	-
kernel	Seamless kernel upgrade	Vladimir Davydov
crtools/kernel	NFS	-
crtools	Validate .img files	-	For a given set of image files check, that they are in "restorable" shape
crtools	Restore a process tree	-	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	X app	-	Dump/restore of graphical applications
kernel	Undo semaphores	Cyrill Gorcunov	Require mods from both sides -- criu and kernel
crtools	More detailed RPC fail codes	-	Currently only success = false is reported :(
