What ever created these is not labelling them correctly, or udev is not labeling them. matchpathcon /dev/dm-0 /dev/dm-0 system_u:object_r:fixed_disk_device_t:s0 matchpathcon /dev/dasda /dev/dasda system_u:object_r:fixed_disk_device_t:s0 (In reply to comment #0) > Description of problem: > inspired by bz#675996 > > Version-Release number of selected component (if applicable): > selinux-policy-targeted-3.7.19-70.el6.noarch > selinux-policy-3.7.19-70.el6.noarch > > How reproducible: > always > > Steps to Reproduce: > # cat /proc/partitions > major minor #blocks name > > 94 0 7212240 dasda > 94 1 7212144 dasda1 > 94 4 7212240 dasdb > 94 5 7212144 dasdb1 > 94 8 7212240 dasdc > 94 9 7212144 dasdc1 > 94 12 7212240 dasdd > 94 13 7212144 dasdd1 > 253 0 27308032 dm-0 > 253 1 1015808 dm-1 > 253 2 512000 dm-2 > # find /dev -context *:device_t:* \( -type c -o -type b \) -printf "%p %Z\n" > /dev/dasd_eer system_u:object_r:device_t:s0 > # what is /dev/dasd_eer ??? # ls -l /dev/dasd_eer # matchpathcon /dev/dasd_err
/dev/dasd_err system_u:object_r:fixed_disk_device_t:s0
It's a char device..
# ls -lZ /dev/dasd_eer
crw-rw----. root root system_u:object_r:device_t:s0 /dev/dasd_eer
# rm /dev/dasd_eer
# echo add > /sys/devices/virtual/misc/dasd_eer/uevent
# ls -lZ /dev/dasd_eer
crw-rw----. root root system_u:object_r:device_t:s0 /dev/dasd_eer
Hmm... but udev definitely calls (ltrace)

grep /dev/das /etc/selinux/targeted/contexts/files/file_contexts /dev/dasd[^/]* -b system_u:object_r:fixed_disk_device_t:s0 Ok the regex only matches block devices. We need to add /dev/dasd[^/]* -c system_u:object_r:fixed_disk_device_t:s0 Fixed in selinux-policy-3.7.19-71.el6 An advisory has been issued which should help the problem described in this bug report.
