Description Milos Malik 2018-08-28 14:13:11 UTC
+++ This bug was initially created as a clone of Bug #1488322 +++

Description of problem:
/dev/mtd0 is a character device, but current SELinux policy file contexts are defined for block devices.

Version-Release number of selected component (if applicable):
selinux-policy-3.13.1-220.el7.noarch
selinux-policy-targeted-3.13.1-220.el7.noarch

How reproducible:
* always when the device is available

Steps to Reproduce:
1. get a RHEL 7.x machine equipped with a Memory Technology Device (MTD)
2. ls -Z /dev/mtd*
3. matchpathcon /dev/mtd*

Actual results:
# semanage fcontext -l | grep mtd
/dev/mtd.*    block device    system_u:object_r:fixed_disk_device_t:s0 
#

Expected results:
# semanage fcontext -l | grep mtd
/dev/mtd.*    character device    system_u:object_r:fixed_disk_device_t:s0 
#
