OpenLMI-Storage provider needs a policy. The provider should be allowed to manipulate with storage stuff, i.e. create/delete/modify/monitor partitions, raids, LVM, mounts etc. and also probe the system for storage devices.

As instructed, I created dummy policy and put it into kernel:

$ cat storagepol.te 


$ make -f /usr/share/selinux/devel/Makefile storagepol.pp
$ semodule -i storagepol.pp

$ chcon -t pegasus_openlmi_storage_exec_t /usr/libexec/pegasus/pycmpiLMI_Storage-cimprovagt
(that's the provider executable)

Audit messages from my test suite are attached (incl. many duplicate messages).
Comment 1 Jan Safranek 2013-06-27 09:25:57 EDT
Looking at the list, it contains some things, that can be easily fixed on OpenLMI side, e.g. writing to /tmp/log is just for debugging purposes. Also creating /tmp/sqGeMO and mounting a btrfs to it (!) should be probably fixed in Blivet, at least it should use /run/blivet

Feel free to suggest which bad practices should we avoid, I guess there is plenty of them, Blivet is from Anaconda and it was never meant to be confined.

Going to work on this tomorrow. I got also a policy with AVC msgs for another provider.
Comment 3 Miroslav Grepl 2013-07-26 04:08:37 EDT
could you pls add to your mypol.te the following rules

type pegasus_openlmi_storage_tmp_t;

manage_files_pattern(pegasus_openlmi_storage_t, pegasus_openlmi_storage_tmp_t, pegasus_openlmi_storage_tmp_t)
manage_dirs_pattern(pegasus_openlmi_storage_t, pegasus_openlmi_storage_tmp_t, pegasus_openlmi_storage_tmp_t)
files_tmp_filetrans(pegasus_openlmi_storage_tmp_t, pegasus_openlmi_storage_tmp_t, { file dir})







and re-test it with these rules. Should cleanup AVCs.

Thank you.
