|---|---|---|---|
| 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 :( |
