exec: failed to write to cgroup.procs #476

chavafg · 2019-03-12T22:26:47Z

Description of problem

There have been some random failures with the hot plug CPUs and cri-o tests. Digging a little bit more into the failures, both are failing when running an exec command as follows:

cri-o failure:

seems like this is a known issue that was already fixed opencontainers/runc#1916

jodh-intel · 2019-03-13T10:32:25Z

Does someone want to pick up re-vendoring runc with this issue?

chavafg · 2019-03-13T13:25:10Z

I can do it, but to what revision should I revendor?
ccb5efd37fb7c86364786e9137e22948751de7ed is v1.0.0-rc6, which is latest release and has the fix in it.
or do we want a newer revision?

This runc revision contains fixes for: `failed to write to cgroup.procs` when running `exec` command. Fixes: kata-containers#476. Signed-off-by: Salvador Fuentes <[email protected]>

@devimc could you investigate this issue as it seems to cause a bunch of instabilities in our CI. Also, from what I gathered from @chavafg feedback, #477 might not be enough.
@chavafg @devimc please let us know what is the status on this issue as we want to fix it asap to get a more reliable CI, as we're delaying PRs right now because the CI never gets green on the first pass.

The agent vendoring needs to be updated regarding the libcontainer dependency so that it does not run into the following issue: "failed to write to cgroups.proc" when running "kata-runtime exec" commands. Commit bd3c4f844abed063a0d0a8575eb596159f33732c is included through this vendoring: Fix race in runc exec There is a race in runc exec when the init process stops just before the check for the container status. It is then wrongly assumed that we are trying to start an init process instead of an exec process. This commit add an Init field to libcontainer Process to distinguish between init and exec processes to prevent this race. In order to prevent from breaking Kata Containers with this commit, we have to provide explicit information if the process is the init process or not, depending if we're creating a new container or exec'ing a process on an existing container. The patch is part of this vendoring update. Fixes kata-containers#476 Signed-off-by: Sebastien Boeuf <[email protected]>

Reopening this issue as #490 was reverted and we are still getting exec failures.

@lifupan did you get a chance to investigate the failures related to the new libcontainer vendoring?

Hi @sboeuf , yes, actually I've dug on this issue and had found some clue about it.

Oh nice, please share and submit any fix you got :)

lifupan · 2019-04-03T13:47:29Z

Hi @sboeuf some info to update here:
I had found the root cause for shimv,2 failed on latest libcontainer, but the fix will bring
another issue for shimv2, I'm debugging on how to solve it definitely, once I had figure out the patch,
I'll send it later.

sboeuf · 2019-04-03T14:24:39Z

Great! Thanks @lifupan 👍

lifupan · 2019-04-11T12:21:55Z

Hi @sboeuf
Since those PR kata-containers/runtime#1494 and
#526
have been merged, I think it's time to make your patches return.
