The attached patches fix a bug that occurs in netlink_send hook functions for both the dummy security module and the SELinux security module. This bug causes incorrect permission denials for netlink messages. Thanks to James Morris for finding this bug. To apply the first patch, save it to
'lsm-netlink.patch', change to the lsm directory and run 'patch -p1 <
~/lsm-netlink.patch'. To apply the second patch, save it to
'selinux-netlink.patch', change to the selinux directory, and run
'patch -p1 < ~/selinux-netlink.patch'. Then, rebuild and reinstall the
kernel in the usual way.
