Remove OpenSSL version checking Resolves: Bug#1155070
2014-10-24 11:48:26 +00:00
From 10636fbfd51320c8ca8b40651bf3e959211ca921 Mon Sep 17 00:00:00 2001
From: Nikolai Kondrashov <Nikolai.Kondrashov@redhat.com>
Date: Tue, 21 Oct 2014 18:30:05 +0300
Subject: [PATCH 1/1] Add --disable-openssl-version-check option
Add "--disable-openssl-version-check" configure option, which removes
checking for vulnerable OpenSSL versions. It is supposed to be used by
downstream packagers and distributions who have other means to ensure
vulnerabilities are fixed, such as versioned package dependencies and
vulnerability handling processes.
This avoids the necessity of editing radiusd.conf on package upgrade to
make sure it keeps working. At the same time, it provides safe default
to those installing FreeRADIUS from source.
