Podsumowanie: SELinux is preventing /usr/sbin/hald "getattr" access to device /dev/etherd/e1.0. This is aoe (ATA-over-Ethernet, modprobe aoe) block device and should be labelled as such.

I will add this mapping to -50 package. /dev/etherd/.+ -b gen_context(system_u:object_r:fixed_disk_device_t,mls_systemhigh) You can test this locally be executing # semanage fcontext -a -t fixed_disk_device_t -f -b "/dev/etherd/.+" Fixed in selinux-policy-3.6.32-50.fc12.noarch
Thank you for prompt action. I suspect that this policy would be too broad. /dev/etherd/ contains some control files also: # ls -lZ /dev/etherd/ c-w--w----. root disk system_u:object_r:device_t:s0 discover brw-rw----. root disk system_u:object_r:device_t:s0 e1.0 cr--r-----. root disk system_u:object_r:device_t:s0 err c-w--w----. root disk system_u:object_r:device_t:s0 flush c-w--w----. root disk system_u:object_r:device_t:s0 interfaces c-w--w----. root disk system_u:object_r:device_t:s0 revalidate As far as I know only e*.* files are disk drives. First number is shelf number which could go quite high; second number is slot, which is limited to 16 I think.
Well the context will only match blk devices, so this is only a problem if blkdevices exist in this path that are not fixed devices. The question I have is what should I label the chr devices. Do you know of devices that match the functionality of these.
Hm, I'm mere user of AOE. For similar special control devices I found, with corresponding label: system_u:object_r:device_t:s0 /dev/btrfs-control system_u:object_r:lvm_control_t:s0 /dev/mapper/control system_u:object_r:fixed_disk_device_t:s0 /dev/raw/rawctl So no real consistency here. Nb. tightening aoe policy would probably require changing labels in aoetools-23-3.fc12.x86_64 package.
For now I am going to label them all lvm_control.
