+Subject: [PATCH] dracut-install: preserve extended attributes when copying
+ files
+
+Preserve extended attributes when copying files using dracut-install.
+
+The copying of extended attributes avoids file execution denials when
+the Linux Integrity Measurement's Appraisal mode is active. In that mode
+executables need their file signatures copied. In particular, this patch
+solves the problem that dependent libaries are not included in the
+initramfs since the copied programs could not be executed due to missing
+signatures. The following audit record shows the type of failure that
+is now prevented:
+
+type=INTEGRITY_DATA msg=audit(1477409025.492:30065): pid=922 uid=0
+ auid=4294967295 ses=4294967295
+ subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
+ op="appraise_data" cause="IMA-signature-required"
+ comm="ld-linux-x86-64"
+ name="/var/tmp/dracut.R6ySa4/initramfs/usr/bin/journalctl"
