From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040510 Description of problem: The context associated with the slaves directory is incorrect, since it doesn't allow bind to write zone files it downloads from master servers in there. It has to be named_cache_t. Version-Release number of selected component (if applicable): bind-9.2.3-18 selinux-policy-targeted-1.14.1-5 How reproducible: Always Steps to Reproduce: 1.start bind with a config file that requires slave zones to be stored in the slaves dir, in the chroot Actual Results: selinux won't let it. Expected Results: it should. Additional info:
Could you send me the AVC Messages?
Not easily. I ended up reinstalling FC3test1 with SELinux disabled on all my boxes, because SELinux, as it stands, would take me too much work to add file_contexts rules such that my home dir, that is a mess of soft links, would work.
If you tried targeted policy there should not be a problem. Homedirectories don't matter that much. But you could still generate the bind error since it runs under policy.
This is now fixed. The /var/named/chroot/named/slaves directory was not being created - it now is, with ownership named:named, the same as the /var/named/slaves directory, while /var/named and chroot/var/named have ownership root:named. This is now in bind-9.2.4rc6-1 in fc3-head.
I tried the targeted policy, it didn't work because I have stuff like squid and sendmail writing to the partition that also contains my home dir. As for the contexts defined in the policy, it's still not right. selinux-policy-*-1.15.9-1 define contexts for /var/named/slave, not /var/named/slaves, both in root and chroot.
This is now fixed (selinux-policy-targeted-1.17.4-1 and bind-9.2.4rc7-9).
I've finally tried again an install of rawhide from scratch with SELinux enabled, and I can now confirm that it works. Thanks,
