Did you received the e-mail with all explanations and the attached .tar.gz file
with the required log?
Thanks

Could you attach your audit.log? Looks like you might have some
labeling problem. Also what version of policy are you running?
What platform?
The question now is:
¿Where need I put all this?
Thanks

Yes, cups-pdf is a "virtual printer" thar prints the ouput into pdf
files. That pdf files are saved by cups-pdf into user's home

As you said fine, I need to allow cups to write into that
directories (including /root) or into a $HOME/cups-pdf-docs
directory to disallow cups all control over $HOME directory.
If I remember well, cups is launched as root user (where a test I
had done some days ago because were a "cups-pdf" prerrequisite -
don't remember now).
How can I solve the issue with home directories?
If anybody knows how to, I would like to solve the problem in this
form:
1) Allowing cups writing into home directories or especific
subdirectory into $HOME.
2) Enablilng SELinux as restrictive I can (is my laptop and I
want to learn a more about SELinux and apps issues.
As a start you might try:
# setsebool -P cupsd_disable_trans 1
This would turn off SELinux protection for the cups daemon, whilst
leaving you able to have SELinux turned on for everything else.
An alternative that might be worth trying would be to change the
context of any directories you want cups to be able to write to,
something like:
# chcon -t print_spool_t $HOME/cups-pdf-doc
Not sure if that'll work though.
I kind of like that solution. See what avc messages you get and we
could maybe add a boolean to allow searching of the users homedirs
for this directory.
Paul.
