- update to 2.0.10
  - Fix compiling on Alpine Linux.
  - Stop printf compiler warning on Alpine Linux due to rlim_t. 
  - manpage cosmetic.
  - Fix removing snmpd read threads when snmpd becomes unavailable.
  - Update to support libipset version 7.
  - Use ipset_printf for ipset messages so can go to log. 
  - When opening files for write, ensure files can only be read by
    root.  Issue #1048 referred to CVE-2018-19046 regarding files
    used for debugging purposes could potentially be read by non
    root users.  This commit ensures that such log files cannot be
    opened by non root users.
  - Disable fopen_safe() append mode by default If a non privileged
    user creates /tmp/keepalived.log and has it open for read (e.g.
    tail -f), then even though keepalived will change the owner to
    root and remove all read/write permissions from non owners, the
    application which already has the file open will be able to
    read the added log entries.  Accordingly, opening a file in
    append mode is disabled by default, and only enabled if
    --enable-smtp-alert-debug or --enable-log-file (which are
    debugging options and unset by default) are enabled.  This
    should further alleviate security concerns related to
    CVE-2018-19046.
  - vrrp: add support to constant time memcmp.  Just an update to
    use best practise security design pattern. While comparing
    password or hmac you need to ensure comparison function is time
    constant in order to figth against any timing attacks. We turn
    off potential compiler optimizations for this particular
    function to avoid any short circuit.
  - Make sure a non privileged user cannot read keepalived file
    output Ensure that when a file such as /tmp/keepalived.data is
    written, no non privileged can have a previous version of that
    file already open, thereby allowing them to read the data.
    This should fully resolve CVE-2018-19046.

From b7a98f9265ffb5927c4d54c9a30726c76e65bb52 Mon Sep 17 00:00:00 2001
From: Quentin Armitage <quentin@armitage.org.uk>
Date: Sat, 10 Nov 2018 19:03:47 +0000
Subject: [PATCH] Update to support libipset version 7
Issue #1058 reported that keepalived failed to build with libipset
version 7. This commit updates keepalived to detect if the version
of the keepalived libraries is pre v7 or not, and compiles
appropriately.
