Subject: OSPF: Fix infinite loop in OSPF Graceful Restart
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=461f177b1cf1600b4a69d9ca4ba1bddfa22b0527;p=thirdparty%2Fbird.git

OSPF: Fix infinite loop in OSPF Graceful Restart

The loop tests 'j' but increments 'i', so 'j' never changes
and the loop never terminates.
