From fb469840b8c34b2f95b40a64b271f245cc1075b7 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sun, 10 Dec 2006 10:45:28 +1100 Subject: [CRYPTO] all: Check for usage in hard IRQ context Using blkcipher/hash crypto operations in hard IRQ context can lead to random memory corruption due to the reuse of kmap_atomic slots. Since crypto operations were never meant to be used in hard IRQ contexts, this patch checks for such usage and returns an error before kmap_atomic is performed.
