From b32ad9144ba680cd953735b2d382bf7f7fc379cc Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Thu, 11 Jul 2019 10:15:13 -0700 Subject: [PATCH] Fix get_special_prop() build failure The cast of the size_t returned by strlcpy() to a uint64_t by the VERIFY3U can result in a build failure when CONFIG_FORTIFY_SOURCE is set. This is due to the additional hardening. Since the token will always fit in strval the VERIFY3U has been removed.
