Dan, Has this been fixed in an selinux-policy update? Fixed in the latest selinux-policy. yum update selinux-policy Bug not fixed in Fedora Core 8 updates. ================================================================================ Summary SELinux is preventing /sbin/rpc.statd (rpcd_t) "write" to pipe (automount_t). Detailed Description SELinux denied access requested by /sbin/rpc.statd. It is not expected that this access is required by /sbin/rpc.statd and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access You can generate a local policy module to allow this access - see http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385 Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended. Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package.

How easy is it to reproduce this? How frequently are you seeing it? Since we've gone through and ensured that FD_CLOEXEC is set on file handles I believe the leaked file descriptors issue must be due to a fork happening between an open (or socket) call and the subsequent setting of the FD_CLOEXEC flag.

F-7 patch to prevent fork between fd open and setting of FD_CLOEXEC
Created attachment 289849 [details]
F-8 and development patch to prevent fork between fd open and setting of FD_CLOEXEC.
I've applied the above patches to F-7 (autofs-5.0.1-30), F-8 (autofs-5.0.2-22) and development. I've requested pushing of the F-7 and F-8 updates to testing. There's no indication as to how frequent these reports are and we do need feedback on the success or otherwise of this attempt at resolving the issue. Please test the revisions as soon as you can. Ian My /etc/auto.misc has the following line: ================================================================================== node55 -fstype=nfs,soft,intr,retry=30,rsize=8192,wsize=8192 node55:/home/user ================================================================================== Whenever I try to mount the above and go to the /misc/node55 folder, I get the above error. (In reply to comment #10) > node55 -fstype=nfs,soft,intr,retry=30,rsize=8192,wsize=8192 > node55:/home/user You should remove the "soft" mount option it's not really appropriate for autofs. I don't think that is related to this problem. Try the build that's been set to testing but I'm not sure we've actually identified the source of the problem yet. Ian This message is a reminder that Fedora 7 is nearing the end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 7. 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 '7'. 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 7'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 7 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. 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. If possible, it is recommended that you try the newest available Fedora distribution to see if your bug still exists. Please read the Release Notes for the newest Fedora distribution to make sure it will meet your needs: http://docs.fedoraproject.org/release-notes/ The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 7 changed to end-of-life (EOL) status on June 13, 2008. Fedora 7 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. |
