2014-12-25udhcpd: account for script delay in leaseJohn Schroeder

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>
2014-11-27libbb: use sendfile() to copy data between file descriptorsBartosz Golaszewski
Busybox already uses sendfile in httpd. This patch proposes to use it globally to copy data between file descriptors. It speeds up the copying on slow systems a lot - below are the times needed to copy a 450Mb file with and without this option enabled on a BeagleBone Black: sendfile: user 0m0.000s sys 0m8.170s read/write 4k: user 0m0.470s sys 0m16.300s function old new delta bb_full_fd_action 394 474 +80 Signed-off-by: Bartosz Golaszewski <bartekgola@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2014-10-30udhcpd: add option for tweaking arppingMichel Stam
Some clients have a very short timeout for sending the DHCP DISCOVER, shorter than the arpping timeout of 2000 milliseconds that udhcpd uses by default.

2014-10-02ntpd: don't stay at short polling intervalMiroslav Lichvar
To avoid polling servers frequently slowly increase the interval up to BIGPOLL when - no replies are received from a peer - no source can be selected - peer claims to be unsynchronized (e.g. we are polling it too frequently) When recv() returns with an error, drop code to try to continue on network errors: I'm not convinced those cases happen in real life. function old new delta recv_and_process_peer_pkt 919 838 -81 Signed-off-by: Miroslav Lichvar <mlichvar@redhat.com> 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>
