RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Subhendu Ghosh 2015-10-20 18:40:48 UTC
Description of problem:
https://github.com/docker/docker/issues/17190

Docker 1.8 has a race condition and can corrupt /etc/hosts inside a container 

Google is coordinating a temp fix for the distros since upstream is pushing the issue out to upstream 1.9 for a fix.


Expected results:


Additional info:

Comment 1 Daniel Walsh 2015-10-20 18:49:21 UTC
As soon as they have a fix, we can patch this, but I am not sure if we are releasing anything before we ship docker-1.9?

Comment 2 Daniel Walsh 2015-10-28 17:26:34 UTC
Looks like googles fix will be outside of docker.

So we can say this is partially fixed in docker-1.9. With more fixes coming in docker-1.10.

Comment 3 Daniel Walsh 2016-01-06 19:45:55 UTC
Fixed in docker-1.10

Comment 5 Luwen Su 2016-02-03 09:29:54 UTC
In docker-1.9.1-15.el7.x86_64,
use this https://github.com/docker/docker/issues/17190#issuecomment-149437458,
the file looks good
# docker exec test-master cat /etc/hosts
172.17.0.2	f988d8d83483
127.0.0.1	localhost
::1	localhost ip6-localhost ip6-loopback
fe00::0	ip6-localnet
ff00::0	ip6-mcastprefix
ff02::1	ip6-allnodes
ff02::2	ip6-allrouters

Comment 6 Lokesh Mandvekar 2016-02-03 15:53:20 UTC
i'm moving this back to MODIFIED as per Dan's comment and scheduling this for 1.10 update.

Comment 9 Lokesh Mandvekar 2016-04-19 16:10:37 UTC
changing component to docker-latest

Comment 11 Alex Jia 2016-04-29 10:50:18 UTC
It works well on docker-latest-1.10.3-19, so moving the bug to VERIFIED status.
