mediawiki math with selinux

[Kiwon Um]

Hello.
I'm a Fedora8 user.

Because the yum pack was not latest version, I installed MediaWiki-1.12.0 from the official website, and all is fine except math function.

I'm now using texlive 2007 for my latex system.
So I modified the render.ml file in the wiki/math folder.

...
let cmd_dvips tmpprefix = "/usr/local/texlive/2007/bin/i386-linux/dvips -q -R -E " ^ tmpprefix ^ ".dvi -f >" ^ tmpprefix ^ ".ps"
let cmd_latex tmpprefix = "/usr/local/texlive/2007/bin/i386-linux/latex " ^ tmpprefix ^ ".tex >/dev/null"
let cmd_dvipng tmpprefix finalpath = "/usr/local/texlive/2007/bin/i386-linux/dvipng -gamma 1.5 -D 120 -T tight --strict " ^ tmpprefix ^ ".dvi -o " ^ finalpath ^ " >/dev/null 2>/dev/null"
...

Although the equations are rendered well, I'm now getting a selinux alert:

Summary:

SELinux is preventing the texvc from using potentially mislabeled files
anon_inode (anon_inodefs_t).

Detailed Description:

SELinux has denied the texvc access to potentially mislabeled files anon_inode.
This means that SELinux will not allow httpd to use these files. Many third
party apps install html files in directories that SELinux policy cannot predict.
These directories have to be labeled with a file context which httpd can access.

Allowing Access:

If you want to change the file context of anon_inode so that the httpd daemon
can access it, you need to execute it using chcon -t httpd_sys_content_t
'anon_inode'. You can look at the httpd_selinux man page for additional
information.

I've couldn't change the file context of 'anon_inode', it's nowhere......
How can I solve this?
