Description Martin Milata 2013-07-16 10:26:59 UTC

This is RHEL6 counterpart to Fedora bug #984549.

In order to fix #977981, system-config-kdump must be permitted to access the bootloader configuration on systems that boot using EFI. In particular, s-c-kdump (and grubby which is invoked by s-c-kdump) needs write access to /boot/efi/EFI/redhat/grub.cfg. It might be relevant that the EFI partition on /boot/efi has FAT32 file system.

Let me know if you want any other information, I have borrowed EFI-capable laptop to try things out on.

Martin, could you please check if the bug is fixed in the current policy?
(selinux-policy-3.7.19-210.el6.noarch or higher)

You can get the selinux-policy packages from Brew or from here:

I'm sorry, I already returned the EFI laptop I tested this on.

Comment 6 Michal Trunecka 2013-08-16 09:22:06 UTC

Ok, we'll leave just as policy check.

I've read the erratum at http://rhn.redhat.com/errata/RHBA-2013-1598.html but I'm unclear on whether the selinux policy changes described in this erratum will be included in future RHEL6.x versions.  Can you clarify please when these policy changes are integrated into new versions?

Comment 10 Miroslav Grepl 2013-11-25 12:26:46 UTC

-fs_read_dos_files(kdumpgui_t)
+fs_manage_dos_files(kdumpgui_t)

has been added to RHEL6.5. So s-c-kdump is allowed to manage files on dosfs_t.
