(was: Thanks for creating a report! The issue has entered the triage process. That means the issue will wait in this status until a Bug Marshal has an opportunity to review the issue. Once the issue has been reviewed you will receive comments regarding the next steps towards resolution.

A good first step is for you to review the [Asterisk Issue Guidelines|https://wiki.asterisk.org/wiki/display/AST/Asterisk+Issue+Guidelines] if you haven't already. The guidelines detail what is expected from an Asterisk issue report.

Then, if you are submitting a patch, please review the [Patch Contribution Process|https://wiki.asterisk.org/wiki/display/AST/Patch+Contribution+Process].

Please note that once your issue enters an open state it has been accepted. As Asterisk is an open source project there is no guarantee or timeframe on when your issue will be looked into. If you need expedient resolution you will need to find and pay a suitable developer. Asking for an update on your issue will not yield any progress on it and will not result in a response. All updates are posted to the issue when they occur.)

>    Affects Versions: 13.31.0

> When starting Asterisk under CentOS 7 I get the following audit log message:
> {noformat}
> type=AVC msg=audit(1583334492.502:2469): avc:  denied  { search } for  pid=28909 comm="asterisk" name="net" dev="proc" ino=1405 scontext=system_u:system_r:asterisk_t:s0 tcontext=system_u:object_r:sysctl_net_t:s0 tclass=dir permissive=0
> {noformat}
> I have isolated this to res_pjsip.so by setting {{autoload=no}} and loading modules one at a time.  Unknown when this problem started, 13.31.0 is the first version I've tried chan_pjsip.  I haven't noticed any problems caused by the AVC denial though I'm positive many features of chan_pjsip are going unused in my deployment.
