Nice, we have a problem with exec.

Curious how you found there was an issue with exec, all the github actions job logs says that it has been cancelled.

Sure.

It has been cancelled because of timeout. The timeout is happening because one of the bats tests hangs. The output from the test shows the last successful test, if you take a look at a log from a successful run you'll see the next test is runc exec --cap. When I tried the same test locally, and then I saw that in fact every test case which involves exec and has stdin is hanging in the same way.

1. I suspect this is a kernel bug, reported it here: https://lore.kernel.org/linux-fsdevel/20250122020850.2175427-1-kolyshkin@gmail.com/T/#u.
2. I have also reported this issue to Golang: io: Copy to a pipe prevents process exit (Go 1.24rc2 on Linux regression) golang/go#71375

Opened #4602 to track this for runc.

Interesting; great digging! Seems like moby may be missing a test-case for this, or at least I recall my test-PR with go 1.24rc1 completed succesfully

LGTM, thanks for catching/fixing the issue in go rc releases too!
