From ccb778e1841ce04b4c10b39f0dd2558ab2c6dcd4 Mon Sep 17 00:00:00 2001 From: Neil Horman Date: Tue, 5 Aug 2008 14:13:08 +0800 Subject: crypto: api - Add fips_enable flag Add the ability to turn FIPS-compliant mode on or off at boot In order to be FIPS compliant, several check may need to be preformed that may be construed as unusefull in a non-compliant mode. This patch allows us to set a kernel flag incating that we are running in a fips-compliant mode from boot up. It also exports that mode information to user space via a sysctl (/proc/sys/crypto/fips_enabled). Tested successfully by me.
