Enabling Checkpoint/Restore of Rootless Containers
Contributor: Deepak Anand
CRIU currently supports unprivileged checkpoint/restore in limited cases, but rootless containers remain unsupported because they introduce...
Kubernetes Operator for Automated Policy-Based Checkpointing
Contributor: Rupam-It
The Checkpoint-Restore Operator manages checkpoint retention well but has no way to create checkpoints automatically. This project adds a new...
Forensic Checkpointing Framework for Kubernetes
Contributor: Shailja Shaktawat
In Kubernetes, container termination during security incidents results in the loss of critical forensic data. This project automates the capture of...
Coordinated checkpointing of distributed applications
Contributor: Behouba Manassé
The goal of this project is to address the challenge of checkpointing distributed applications, which generally run across multiple nodes with active...
Files on Detached Mounts
Contributor: Bhavik Sachdev
If a mount is unmounted using the MNT_DETACH flag, its information disappears from /proc/$pid/mntinfo. If CRIU tries to C/R an fd on such a mount...
Support arm64 Guarded Control Stack (GCS)
Contributor: Igor Svilenkov Bozic
This project aims to enable testing of Guarded Control Stack (GCS) functionality within CRIU (Checkpoint/Restore In Userspace) on AArch64 by...
Support C/R of pidfd descriptors
Contributor: Bhavik Sachdev
pidfds are a feature of the Linux kernel that provide a process with a stable handle on another process. They were introduced to solve the problem of...
CRIU: Add support for checkpoint/restore of CORK-ed UDP socket
Contributor: Juntong Deng
CRIU currently does not support checkpoint/restore for UDP sockets with the UDP_CORK socket option. In order for CRIU to support the UDP_CORK socket...
Kubernetes operator for managing container checkpoints
Contributor: Parthiba
Project Summary: The project aims to enhance Kubernetes container checkpoint management through advanced garbage collection policies. These policies...
Forensic analysis of container checkpoints
Contributor: Behouba Manassé
The goal of this proposal is to address the challenge of investigating the contents of containerized applications, which run in isolation from the...
CRIU: Add support for memfd_secret file descriptors
Contributor: Dhanuka Warusadura
CRIU can checkpoint/restore a trivial hello_word process to running Linux containers. However, with the current implementation of CRIU, it can't...
Forensic analysis of container checkpoints
Contributor: Prajwal S N
The crit library in go-criu was created during GSoC 2022 to enable analysis of CRIU images with tools written in Go. It allows container management...
Porting CRIU Image Tool (CRIT) to Go
Contributor: Prajwal S N
CRIU provides a Python-based tool called CRIT in order to explore and manipulate checkpoint images. To enable hassle-free integration with Go...
CRIU: Support sparse ghosts
Contributor: Liang Chun
Nowadays, CRIU will save the ghost file by using a lot of system calls to determine where the chunks are, which is very expensive, especially for...
Add support for checkpoint/restore read and write queue of UDP socket
Contributor: Bui Quang Minh
In this project, I will implement a new Linux kernel API to help dumping/writing back the read and write queue of UDP socket. Then I will use that...
Add io_uring support
Contributor: Kumar Kartikeya Dwivedi
This project adds support for dump and restore of io_uring instances. The three main goals of this project is to handle dump/restore of empty...
Use eBPF to lock/unlock the network
Contributor: Zeyad Gouda
During checkpointing and restoring, CRIU locks the network to make sure no TCP packets are accepted by the network stack during the time the process...
Port Crit To Go
Contributor: pac23
Crit Encodes/Decodes and exports/displays CRIU's custom images to/from json/binary to json/binary. Porting Crit to Go so that projects using go...
Restrict Checks for Open/Mapped Files
Contributor: Ajay Bharadwaj
While checkpointing (Dumping), CRIU stores some meta-information about the open/mmaped file and this is validated while restoring to make sure that...
Optimize logging engine
Contributor: Prakriti Goyal
During the execution, CRIU writes many logs. Most of these logs are not used, but they are the only way to figure out the reason for failure if some...
Optimizing the pre-dump algorithm
Contributor: Dubey Abhishek
During pre-dump in CRIU, the memory pages of target process are stored in pipe-pages, until the content is not flushed to disk image or page-server....
