Description Jaroslav Aster 2015-07-14 14:42:53 UTC

Hi,

I found the same issue on rhel-7.2 beta. I was not able to boot my notebook, the last message, I saw, was

[!!!!!!] Failed to load IMA policy, freezing

Workaround was to remove /etc/ima directory.

systemd-219-5.el7.x86_64

+++ This bug was initially created as a clone of Bug #1226948 +++

The original systemd IMA module loaded the IMA policy by mmaping the
file into memory and then writing the entire file to
<securityfs>/ima/policy.  By changing this behavior of writing the
entire file,  commit 4dfb18922d5d "ima-setup: simplify"  broke IMA
policy loading.

Version-Release number of selected component (if applicable):

Fedora 22: systemd src/core/ima-setup.c

How reproducible:

Always

Steps to Reproduce:
1. On boot with an IMA policy in /etc/ima/ima-policy (default location)

Actual results:

systemd[1]: Failed to load the IMA custom policy file /etc/ima/ima-policy: Invalid argument
IMA: policy updated failed
[!!!!!!] Failed to load IMA policy, freezing

Expected results:
systemd[1]: Successfully loaded the IMA custom policy /etc/ima/ima-policy
kernel: IMA: policy update completed

Additional info:
Please revert commit 4dfb18922d5d1efb13ee459cbf23832277f85ed7 and the
related hunk in commit 7430ec6ac08f2c0416d9f806964c46b30f3862b2.

This bug was reported by Patrick Ohly.
