From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.3) Gecko/20070417 Fedora/2.0.0.3-4.fc7 Firefox/2.0.0.3 Description of problem: SELinux is reporting AVC messages against openvpn. The avc would indicate allow ifconfig_t openvpn_etc_t:file { read write }; is required. May 10 21:11:23 marie kernel: audit(1178824283.947:1387): avc: denied { read write } for pid=1927 comm="ip" name="ipp.txt" dev=hda1 ino=161417 scontext=root:system_r:ifconfig_t:s0 tcontext=root:object_r:openvpn_etc_t:s0 tclass=file This indicates the ip command is getting read/write access to ipp.txt. I believe this is caused by openvpn opening ipp.txt r/w, and then execing the ip command (Probably in a script). You need to call fcntl(fd, F_SETFD, F_CLOEXEC) On all open file descritptors before fork/exec to prevent these leaked file descriptors. Version-Release number of selected component (if applicable): openvpn-2.1-0.19.rc4.fc7 How reproducible: Didn't try Steps to Reproduce: 1. 2. 3. Actual Results: Expected Results: Additional info:
I'm guessing that this is coming from someone using sample-config-files/server.conf more-or-less unmodified. The fix is probably to just change this line: ifconfig-pool-persist ipp.txt to this: ifconfig-pool-persist /var/run/openvpn/ipp.txt I have a bug open to review the sample config files and fix this sort of thing, but I haven't had a chance to do that yet...
While that may be correct. That will not fix the AVC reported above. That would just require allow ifconfig_t openvpn_var_run_t:file { read write }; Which is not probably correct either. I don't think the "ip" command needs to read write that file. This is being caused because when you open the file in openvpn, you are not setting the close on exec flag.
Based on the date this bug was created, it appears to have been reported against rawhide during the development of a Fedora release that is no longer maintained. In order to refocus our efforts as a project we are flagging all of the open bugs for releases which are no longer maintained. If this bug remains in NEEDINFO thirty (30) days from now, we will automatically close it. If you can reproduce this bug in a maintained Fedora version (7, 8, or rawhide), please change this bug to the respective version and change the status to ASSIGNED. (If you're unable to change the bug's version or status, add a comment to the bug and someone will change it for you.) Thanks for your help, and we apologize again that we haven't handled these issues to this point. The process we're following is outlined here: http://fedoraproject.org/wiki/BugZappers/F9CleanUp We will be following the process here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this doesn't happen again.
This bug has been in NEEDINFO for more than 30 days since feedback was first requested. As a result we are closing it. If you can reproduce this bug in the future against a maintained Fedora version please feel free to reopen it against that version. The process we're following is outlined here: http://fedoraproject.org/wiki/BugZappers/F9CleanUp
Not sure if this bug still exists, but all open file descriptors in openvpn should be closed before execing ifconfig. fcntl(fd, F_SETFD, F_CLOSEXEC)
Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. 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 '9'. 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 9'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 9 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 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 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.
