From 3fc89adb9fa4beff31374a4bf50b3d099d88ae83 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Mon, 19 Oct 2015 18:23:57 +0800 Subject: crypto: api - Only abort operations on fatal signal Currently a number of Crypto API operations may fail when a signal occurs. This causes nasty problems as the caller of those operations are often not in a good position to restart the operation. In fact there is currently no need for those operations to be interrupted by user signals at all. All we need is for them to be killable. This patch replaces the relevant calls of signal_pending with fatal_signal_pending, and wait_for_completion_interruptible with wait_for_completion_killable, respectively.
