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 
policy_module(mypol,1.0)

pegasus_openlmi_domain_template(storage)

$ 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 13:25:57 UTC
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.

Comment 2 Miroslav Grepl 2013-06-27 19:18:25 UTC
Going to work on this tomorrow. I got also a policy with AVC msgs for another provider.

Comment 3 Miroslav Grepl 2013-07-26 08:08:37 UTC
Jan,
could you pls add to your mypol.te the following rules

type pegasus_openlmi_storage_tmp_t;
files_tmp_file(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})

storage_rw_inherited_fixed_disk_dev(pegasus_openlmi_networking_t)

modutils_domtrans_insmod(pegasus_openlmi_storage_t)

udev_domtrans(pegasus_openlmi_storage_t)

optional_policy(`
    lvm_domtrans(pegasus_openlmi_storage_t)
')

optional_policy(`
    mount_domtrans(pegasus_openlmi_storage_t)
')

optional_policy(`
    raid_domtrans_mdadm(pegasus_openlmi_storage_t)   
')


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

Thank you.
