From e65e9acb201ba2cf3f1b0b209b45d557577d8044 Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Sat, 16 Apr 2022 13:31:38 +0200 Subject: [PATCH] package/urandom-scripts: do not seed if initial seed doesn't exist By returning a failure in the event that the initial seed doesn't exist, we'd then skip creating a new seed, which means we'd never in fact have an initial seed, and this script is therefore useless. Fix this by checking for the existence of the seed file first, and just returning 0 if it's not there. Reported-by: Nicolas Cavallari Reported-by: Eugen Hristev Signed-off-by: Jason A.
