Commit "zcip: fix link-local IP conflict detection" has introduced wrong comparsion of source IP with our IP. This leads to a new IP being picked unnecessarily on every incoming ARP packet.

2015-03-22ifupdown: correct ifstate update during 'ifup -a'. Closes 6212Frank Bergmann
When 'if -a' runs into an failure on an interface all further interfaces won't be correctly updated in ifstate. This patch inserts a new variable that only tracks the current interfaces failure so that the write to ifstate can rely on this and not the one for the functions return value.

2014-12-21udhcpc: account for script run timeDenys Vlasenko
Based on the following user report: I ran into an issue where I was seeing a long delay in the scripts called in udhcp_run_script. I was using an old version of OpenWrt (kamikaze) and a satellite modem. An NTP script was being called and the modem would sometimes take a long time to respond to the DNS lookup when it was offline. This delay started affecting my lease time. The lease that I would get from my satellite modem before it was online would be short: only 60 seconds. The delay with NTP and the modem would typically be about 18 seconds. This would cause the first DHCP renew request from dhcpc to be a little late. Under certain circumstances, I could even see the first DHCP renew to occur after the lease had expired! function old new delta udhcpc_main 2816 2837 +21 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2014-07-20zcip: fix link-local IP conflict detectionKen Sharp
During link-local IP resolution, if a regular ARP request is received during the ARP probe period, it will incorrectly cause a target IP conflict. This then leads to a new IP being picked unnecessarily. Per RFC 3927, section 2.2.1, we should flag a target IP conflict only if the source IP is null, the target IP matches our IP, and the source hw addr does not match our hw addr. function old new delta zcip_main 1354 1322 -32 Signed-off-by: Ken Sharp <ken.sharp@ni.com> Signed-off-by: Ben Shelton <ben.shelton@ni.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
