Todo

component	task	assignee	status	comments
crtools/kernel	memory snapshot	xemul@	-	need to take mem snapshot in kernel for iterative migration, (probably) rebootless upgrade and HA
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	Shared objects (mm/fs/fdtable) support	avagin@	not implemented	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@	not implemented	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
kernel	Proc fdinfo extension	gorcunov@	in progress	Need to rework and resubmit the patches
kernel/crtools	posix timers	skinsbursky@	-	Need new kernel API for a) listing existing timers and b) fetching timer notify configuration.
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 connection fixup	-	-	When we turn repair off a window probe is sent by kernel. It can be lost and we leave with stuck connection. Plus, the keepalive timer isn't rearmed on repaired socket connect, probably this is the way to solve this.
crtools	Iptables	-	-	This is easy. Need to run ipdables-save and iptables-restore
kernel/crtools	Auto namespaces detection	-	-	Now we "detect" them by looking at cmdline options
crtools	Migration w/o intermediate disk	Adrian Reber	-	-
kernel/crtools	TUN/TAP	-	-	-
kernel/crtools	tcpdump	xemul@	-	The diag modules extensions are on their way to net-next. Next is -- socket filters
vzkernel/crtools	OpenVZ kernel support	-	-	Within 3.5 and RHEL7 port
crtools	More sockoptions	-	-
crtools	Bridges in container	-	-
crtools	cgroups in container	-	-
crtools/kernel	NFS	-	-
crtools/kernel	VDSO	-	-	issues: VDSO may change between kernels; vsyscall may change between kernels; VDSO mapping should be VDSO mapping, not regular one
crtools	Unmap a restorer VMA	-	-	Lots of ideas were generated so far.
crtools	file locks	-	-	It's hard to do it carefully. We need to make sure that all lock users are taken into dump. Only support it inside container?
