[Bug 1328975] Re: libc6: getaddrinfo() sends DNS queries to random file descriptors

Additionally, attempting to bring in utopic libc to fix the bug causes dependency resolution problems down the road.

[Bug 1328975] Re: libc6: getaddrinfo() sends DNS queries to random file descriptors
I too cannot understand why this fix was refused to backport to trusty. We just spent two man-weeks tracking down this issue in one of our applications, and to find that a severe race condition in libc was fixed in Debian over a year ago but still not fixed in a *long term supported* version of Ubuntu is ... frustrating, to put it lightly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1328975 Title: libc6: getaddrinfo() sends DNS queries to random file descriptors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/1328975/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1328975] Re: libc6: getaddrinfo() sends DNS queries to random file descriptors
Hi all-- I apologize in advance if this is tracked somewhere here and I'm missing it, but I'm curious to know if this bugfix (and associated downstream packages) are planned to be backported to 14.04 repositories. Would someone mind shedding some light on the backport process/timeline for LTS releases, and the status of this ticket in that regard?
