Subject: Fixes a bug in kernel extended attribute processing.
X-Git-Tag: v1.4.0~44
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2a0130f94d2304e316f0ffad8e52fce094559782;p=thirdparty%2Fbird.git

Fixes a bug in kernel extended attribute processing.

The bug caused that krt_prefsrc attribute was not processed when a route
received from a kernel protocol was exported to another kernel protocol.

Thanks to Sergey Popovich for a bugreport.
