[Bug 1096273] New: repetition of signal 21 with --sig-proxy and SIGSTOP of docker
by Red Hat Bugzilla 05 Apr '16

05 Apr '16

https://bugzilla.redhat.com/show_bug.cgi?id=1096273 Bug ID: 1096273 Summary: repetition of signal 21 with --sig-proxy and SIGSTOP of docker Product: Red Hat Enterprise Linux 7 Version: 7.1 Component: docker Severity: low Assignee: lsm5(a)redhat.com Reporter: ldoktor(a)redhat.com QA Contact: virt-bugs(a)redhat.com CC: admiller(a)redhat.com, golang(a)lists.fedoraproject.org, lsm5(a)redhat.com, mattdm(a)redhat.com, mgoldman(a)redhat.com, skottler(a)redhat.com, vbatts(a)redhat.com Depends On: 1087704 +++ This bug was initially created as a clone of Bug #1087704 +++ Description of problem: I noticed weird reaction to SIGSTOP signal. When you start container with --sig-proxy, ignore all signals in container and from OS use kill -SIGSTOP to the `docker run` process, it's put into background. (so far correct behavior) Than when you use kill -SIGCONT, it's resumed (still in background) and it's continuing to send signal 21 to the container (100% CPU utilization). This disappears once you attach the process with fg. Version-Release number of selected component (if applicable): docker-0.10.0-8.el7.x86_64 docker-io-0.9.1-1.fc21.x86_64 How reproducible: always Steps to Reproduce: 1. /usr/bin/docker -D run --tty=false --rm -i --name test_eoly localhost:5000/ldoktor/fedora:latest bash -c 'for NUM in `seq 1 64`; do trap "echo Received $NUM, ignoring..." $NUM; done; while :; do sleep 1; done' 2. ps ax |grep docker 3. kill -SIGSTOP $PID 4. kill -SIGCONT $PID Actual results: [1]+ Pozastavena /usr/bin/docker -D run --tty=false --rm -i --name test_eoly localhost:5000/ldoktor/fedora:latest bash -c 'for NUM in `seq 1 64`; do trap "echo Received $NUM, ignoring..." $NUM; done; while :; do sleep 1; done' [root@t530 ~]# Received 21, ignoring... Received 21, ignoring... Received 21, ignoring... Received 21, ignoring... Received 21, ignoring... Received 21, ignoring... ... (100% CPU utilization, when you use fg it stops and you can use the container again...) Expected results: [1]+ Pozastavena /usr/bin/docker -D run --tty=false --rm -i --name test_eoly localhost:5000/ldoktor/fedora:latest bash -c 'for NUM in `seq 1 64`; do trap "echo Received $NUM, ignoring..." $NUM; done; while :; do sleep 1; done' [root@t530 ~]# Received 21, ignoring... Additional info: I'm not definitely sure if this is really required as it's not a common usage. But as there is no way to detach the process apart from kill -SIGSTOP people might use it and get to this problem... --- Additional comment from Lukas Doktor on 2014-05-05 03:59:30 EDT --- I retested this with the upstream dc9c28f/0.10.0 with the same results.

[Bug 1204620] New: container stays around wihtout any processes in it
by Red Hat Bugzilla 17 Feb '16

17 Feb '16

https://bugzilla.redhat.com/show_bug.cgi?id=1204620 Bug ID: 1204620 Summary: container stays around wihtout any processes in it Product: Fedora Version: 22 Component: docker-io Assignee: lsm5(a)redhat.com Reporter: mvollmer(a)redhat.com QA Contact: extras-qa(a)fedoraproject.org CC: adimania(a)gmail.com, admiller(a)redhat.com, golang(a)lists.fedoraproject.org, hushan.jia(a)gmail.com, jchaloup(a)redhat.com, jperrin(a)centos.org, lsm5(a)redhat.com, mattdm(a)redhat.com, mgoldman(a)redhat.com, miminar(a)redhat.com, s(a)shk.io, thrcka(a)redhat.com, vbatts(a)redhat.com Created attachment 1005245 --> https://bugzilla.redhat.com/attachment.cgi?id=1005245&action=edit Setup script for reproducing Description of problem: When running a specific custom image (see attachement), docker fails to notice when the single process exits. The container stays around, and attempts to stop or remove it result in errors. Doing the same with a slightly older version of docker shows expected behavior. Version-Release number of selected component (if applicable): docker-io-1.5.0-19.git5d7adce.fc22.x86_64 How reproducible: Always. Steps to Reproduce: 1. Run the attached SETUP script in an empty directory 2. Run the resulting image # docker run --name=probe cp /bin/container-probe 3. After wrestling control back from the hanging "docker run", try to stop or remove the container. # docker stop probe # docker rm -f probe Actual results: The expected output of container-probe is shown, but "docker run ..." does not return to the command line prompt. In fact, job control doesn't work anymore either (C-c, C-z, C-\). Stopping and removing leads to these errors: # docker stop probe Error response from daemon: Cannot stop container probe: active container for c492b7203b3d465c778935f97a12b3bf8a4c442731c7fd25cee6f50798ac4f65 does not exist FATA[0000] Error: failed to stop one or more containers # docker rm -f probe Error response from daemon: Could not kill running container, cannot remove - active container for c492b7203b3d465c778935f97a12b3bf8a4c442731c7fd25cee6f50798ac4f65 does not exist FATA[0000] Error: failed to remove one or more containers Expected results: The output is shown and "docker run" terminates successfully, the container is show as "exited" and can be removed. Additional info: docker-io-1.5.0-1.fc21.x86_64 shows the expected behavior. "docker run -i" return control to the shell, but the resulting container can't be stopped or removed either. "systemctl restart docker" puts the "probe" container into a state where it can be removed. -- You are receiving this mail because: You are on the CC list for the bug.
