Subject: Fixes bug on Linux 2.4.x - kernel sync does not work until restart of kernel protocol.
X-Git-Tag: v1.2.3~9
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=002b6423188abdd62c5a494069fd299b96863a79;p=thirdparty%2Fbird.git

Fixes bug on Linux 2.4.x - kernel sync does not work until restart of kernel protocol.

Which was, actually, a bug in timers - on older kernel, monotonic timer
is missing and the other implementation started with now == 0, which
collides with usage 0 as a special value in timer->expires field.
