Description Subhendu Ghosh 2010-05-09 18:33:37 UTC
Summary:

SELinux is preventing /usr/bin/rsync "create" access on repodata.

Detailed Description:

[rsync has a permissive type (cobblerd_t). This access was not denied.]

SELinux denied access requested by rsync. It is not expected that this access is
required by rsync and this access may signal an intrusion attempt. It is also
possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

Miroslav, we added  httpd_cobbler_content_rw_t but it is not assigned to any files?

Comment 5 Subhendu Ghosh 2010-05-10 22:43:00 UTC
I was doing a cobbler import off a loopback mounted iso

Dan,
I guess this type was originally used for /var/www/cobbler directory. Now we have only this label

/var/www/cobbler/images(/.*)?   gen_context(system_u:object_r:public_content_rw_t, s0)


I think it was Dominic's intent. So we should add the same label for 

/var/www/cobbler/ks_mirror(/.*)? 
gen_context(system_u:object_r:public_content_rw_t, s0)

/var/www/cobbler/links(/.*)? 
gen_context(system_u:object_r:public_content_rw_t, s0)

Will fix this bug.
