sanitize logging messages |
hard |

Currently log messages are placed w/o any logic. Need to improve that ... somehow.

optimize kcmp calls |
medium |
- |
For fs/fdt/vm/etc we can pre-generate ID based on objects that live on them. If pre-ID matches, then call kcmp.

Packing or encrypting the data would be nice. Maybe it's purely for P.Haul?

Modify restored resources run-time |

CRIT Need (probably) some way to alter what is being restored. Usage example -- change the IP address of sockets from task above.

TCP socket migration with changed IP |
medium |
- |
CRIT 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.

Applying images |
hard |
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

Partial migration |
hard |
- |
migrate some tasks while proxying IPC to existing others (pipes->sockets, etc.)

Shared objects (mm/fs) support |
medium |

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.

Smart paths resolution |
hard |
- |
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
