* udhcpd: add option for tweaking arppingMichel Stam2014-10-301-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | 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. This patch allows tweaking the timeout, or disabling of arpping altogether, at the risk of handing out addresses which are already in use. function old new delta udhcpd_main 1460 1501 +41 udhcpc_main 2814 2851 +37 packed_usage 29957 29974 +17 arpping 477 493 +16 find_free_or_expired_nip 161 174 +13 send_offer 285 292 +7 nobody_responds_to_arp 85 89 +4 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 7/0 up/down: 135/0) Total: 135 bytes Signed-off-by: Michel Stam <m.stam@fugro.nl> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* Patch by Andrew Victor,Glenn L McGrath2004-03-051-3/+3
| | | | | | | | | | | In arpping.h, fix structure alignment of "struct arpMsg". GCC can insert padding in the structure which causes udhcpd to send an invalid ARP packet on the network. It will then not receive a valid reply, which can cause it to assign an IP address that's already in use on the network. (With kernels before 2.4.20, the "struct ethhdr" in linux/if_ether.h wasn't marked as packed. This is also an issue if your toolchain was built with a pre-2.4.20 kernel).
