Description Chris Murphy 2018-09-11 22:18:55 UTC
Description of problem:

Three dnssec-trigger AVC's triggered during boot/login (nothing else launched, I see the notification as login to GNOME completes).


Version-Release number of selected component (if applicable):
selinux-policy-3.14.2-34.fc29.noarch

System has had restorecon -rv applied

1.

SELinux is preventing dnssec-trigger- from read access on the chr_file random.

type=AVC msg=audit(1536703714.624:219): avc:  denied  { read } for  pid=1323 comm="dnssec-trigger-" name="random" dev="devtmpfs" ino=1037 scontext=system_u:system_r:dnssec_trigger_t:s0 tcontext=system_u:object_r:random_device_t:s0 tclass=chr_file permissive=1

2.
SELinux is preventing dnssec-trigger- from open access on the chr_file /dev/random.

type=AVC msg=audit(1536703714.624:220): avc:  denied  { open } for  pid=1323 comm="dnssec-trigger-" path="/dev/random" dev="devtmpfs" ino=1037 scontext=system_u:system_r:dnssec_trigger_t:s0 tcontext=system_u:object_r:random_device_t:s0 tclass=chr_file permissive=1


3.
SELinux is preventing dnssec-trigger- from getattr access on the chr_file /dev/random.

type=AVC msg=audit(1536703714.624:221): avc:  denied  { getattr } for  pid=1323 comm="dnssec-trigger-" path="/dev/random" dev="devtmpfs" ino=1037 scontext=system_u:system_r:dnssec_trigger_t:s0 tcontext=system_u:object_r:random_device_t:s0 tclass=chr_file permissive=1


Additional info:

Note that the first one is on the file "random" whereas second and third are on /dev/random - not sure what the distinction is.

Comment 1 Chris Murphy 2018-09-12 00:57:45 UTC
OK and rebooting with enforcing I get only these:

Missed one:
