No way to inherit tty over RPC using pycriu?
Description I am unable to restore an application when using CRIU in either SWRK or standalone service modes. In both modes, the restore fails with:
Error (criu/util.c:641): exited, status=3
Warn (criu/kerndat.c:1117): Can't keep kdat cache on non-tempfs
4959: Error (criu/tty.c:992): tty: Don't have tty to inherit session from, aborting
4959: Error (criu/files.c:1213): Unable to open fd=0 id=0x6
Error (criu/cr-restore.c:2536): Restoring FAILED.
Error (criu/cr-restore.c:1498): 4959 killed by signal 9: Killed
As far as I understand this is because the when in service mode, it is running as a daemon, so no tty-s are associated with it. And when in SWRK mode (started by the pycriu lib with criu_obj.use_binary("/path/to/binary")), the pycriu lib actually intentionally closes all std fds:
https://github.com/checkpoint-restore/criu/blob/317170ce09bdf96fc880bb05a49be1d3b41efae6/lib/py/criu.py#L100-L103
As a result, there are no tty-s to inherit when restoring the process.
Steps to reproduce the issue:
- Start a binary that prints something to stdout as SID leader
- Dump it with the
pycriulib - Try to restore it with
pycriulib - Check the restore logs
Describe the results you received: Restore fails with:
Error (criu/util.c:641): exited, status=3
Warn (criu/kerndat.c:1117): Can't keep kdat cache on non-tempfs
4959: Error (criu/tty.c:992): tty: Don't have tty to inherit session from, aborting
4959: Error (criu/files.c:1213): Unable to open fd=0 id=0x6
Error (criu/cr-restore.c:2536): Restoring FAILED.
Error (criu/cr-restore.c:1498): 4959 killed by signal 9: Killed
Describe the results you expected: Restore succeeds
Current workaround:
I have copied and modified the the pycriu lib by removing the following lines:
https://github.com/checkpoint-restore/criu/blob/317170ce09bdf96fc880bb05a49be1d3b41efae6/lib/py/criu.py#L101-L103
This allows me to use criu for restoring an application in the following way:
>>> import my_pycriu_modified_lib
>>> criu = my_pycriu_modified_lib.criu()
>>> criu.use_binary("/path/to/binary")
>>> # set criu opts
>>> criu.restore() # success

Looks good but some kernel features are missing
which, depending on your process tree, may cause
dump or restore failure.
Additional environment details: This is happening inside a docker container running in privileged mode.
Interesting. I think the Python bindings are not used very much. I had a quick look at the Go bindings and they do not seem to close the FD 0,1,2.
Do you think you could compare your test case with either the C, Go or Rust CRIU bindings to see if they behave differently.
I think the main problem is, that at least the C and Go bindings are actively being used. I do not know if the Python bindings are used a lot.
Sorry, I do not have an easy way to test this with the other bindings (need to create a new container that has them).
But I am pretty sure they will work because:
- When I remove the code that closes FDs 0,1 and 2 the python bindigs work as well
- Restoring directly from the console using the CRIU CLI also works
A friendly reminder that this issue had no activity for 30 days.

@sdimovv are you able to dump the python process with success? I am using below code to dump the process but not sure how to pass opts.images_dir_fd option to criu.
Can you please share how you implemented it? Below is my code.
import os from pycriu.criu import * c=criu() f = os.open("dummy", os.O_DIRECTORY) c.opts.images_dir_fd = f c.use_binary("/home/ec2-user/criu/criu/criu/criu") c.dump()
