[Gllug] CGI Perl and SELinux

[Ken Smith]

Hi Everyone,

I'm in the process of migrating my old FC6 MythTV 0.20 system to Centos 
5.5 Myth 0.23.

I'm testing the Mythweb part of the application streaming in flash 
format. I'd like to try to get it running with SELinux enabled if 
possible. It does work fine without. The Perl CGI script invokes ffmpeg 
to convert the video to .flv format. The command line that the perl 
script runs redirects the output of ffmpeg to /dev/stdout. The error I 
get from Selinux suggests that I run the command:-

chcon -t httpd_sys_content_t 'stdout'

So I guess that the ffmpeg command is being blocked by SELinux because 
the context of /dev/stdout in the Apache/Perl environment isn't to its 
liking

Is there a way to set the SELinux context of the /dev/stdout redirection 
in the Perl/Apache environment?

I think I understand some of the principles here but I'm not quite sure 
how this bit works.

Many thanks for any suggestions.

Ken
