Description of problem: Host lookup is failing after suspend to ram, affecting at least privoxy. This is a new regression in glibc-2.9-3.x86_64, glibc-2.9-2.x86_64 and prior are working correctly. Version-Release number of selected component (if applicable): glibc-2.9-3.x86_64 How reproducible: Every time. Steps to Reproduce: 1. Privoxy is installed and gnome is configured to it. 2. Suspend to RAM 3. Resume from RAM 4. Network manager reconnects to wireless 5. Use epiphany to view a web site Actual results: All websites fail in epiphany with privoxy saying host not found Expected results: Website should appear as normal. Additional info: The only way to fix privoxy appears to be restart it. All DNS lookups fail, even ones not previously tried. privoxy hasn't changed in ages, glibc upgrade caused the problem and reverting it fixed the problem. Strace output to be attached, shows that glibc is not even attempting to look in /etc/resolv.conf after suspend, thus causing the lookup failure.

From the RPM changelog there's a bunch of suspects for hostname lookup breakage in this release of glibc: # rpm -qp --changelog glibc-2.9-3.x86_64.rpm|head * Mon Dec 08 2008 Jakub Jelinek <jakub> 2.9-3 - temporarily disable _nss_dns_gethostbyname4_r (#459756) - NIS hostname lookup fixes (#473073, #474800, BZ#7058)
Has anyone looked at this? This was broken by a stable update to Fedora 10 and the same regression is present in current rawhide, so Fedora 11 will be broken too. glibc-2.9.90-12.x86_64 privoxy-3.0.10-3.fc11.x86_64

This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '10'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 10's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 10 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
