[PATCH] Sysctl.conf parameters not reloaded on restart or start
Last modified: 2015-01-07 19:08:36 EST
See the summary. As the network script does it, so should any initscript that relies on sysctl.conf settings. Patch attached below.
Created attachment 104499 [details] audit.initscript.patch Patch from Jose Plans <jmp@redhat.com>
Or edit /etc/modules.conf to add post-install audit sysctl -e -p /etc/sysctl.conf There is documentation to this effect in the HP EAL3 Certification Guide that will be bundled in U4. I'll look at having the U4 laus %post deal with this.
I have the same issue in sysctl.conf - I have updated it with new parameters and after reboot some changes take and some changes don't take. I then thought it may be a syntax issue, but when i do a sysctl -w and then cut-and-paste the line from my sysctl.conf file - it takes perfectly. So - will the line above added to my modules.conf file re-read the sysctl.conf file? Thanks
The line above should read your sysctl.conf.

OK Charlie - I tried both things mentioned here. Maybe there is a symtax error in my sysctl.conf file - I will attach the sysctl.conf file for you to look at. Thanks for the help.
Hi Dan - I don't see any audit entries in your sysctl.conf. mine look like this: # audit subsystem defaults dev.audit.max-messages = 1024 dev.audit.paranoia = 0 dev.audit.attach-all = 0 dev.audit.allow-suspend = 1 dev.audit.debug = 0
Thanks Charlie - Are those normal entries to have in the sysctl.conf ? I am a bit new to this so please excuse my ignorance. So - If I put those entries in - will it then read the entry in my modules.conf. I am confused I guess. Like I said - some of the entries get applied, but not all of them. Do I have them in the wrong order ? Thanks again for your help.
Are you asking specifically in the context of the laus auditing driver?
I don't even know what the laus auditing driver is. I hope I am not starting to look like a fool. I just want the sysctl.conf entries to be read properly - just like when I run sysctl -w and they all take just fine. In fact - the "patch" that Bastien gave is odd because I don't have an init script called audit.
Ayuh. This is a bug against the laus package. It provides system call auditing - part of getting RHEL3 it's EAL3 security certification. That being said, let me grab my "generalist" hat. In which instances are you not seeing your sysctl parameters re-read?
After re-boot I cat the /proc entries and see that some of the entries are not taking. The VM and NET entries to be specific. Just wondering if I may have a syntax error. I heard a rumor that this is a known problem and will be fixed in U4. That is sue out this month correct ?
This bug is now fixed in laus-0.1-68RHEL3 . By default, there are NO dev.audit entries in /etc/sysctl.conf . With laus-0.1-68RHEL3, there are now two mechanisms whereby audit sysctl settings can be set when the module is loaded: 1. Create a file with only dev.audit settings, and set the variable 'AUDITSYSCTL=<filename>' in /etc/sysconfig/audit Then the audit initscript will load only these sysctl settings after it loads the module. OR: 2. Put 'dev.audit' settings in /etc/sysctl.conf - these will be loaded after the audit initscript loads the module.
