Denys Vlasenko	a1a77ad5ea	udhcpc[6]: untangle "timeout" and "remaining lease"; reduce min lease to 30 seconds This allows to fix a problem that we wait for renew replies for up to half the lease (!!!) if they never come. Make it so that lease of 60 seconds is not "rounded up" to 120 seconds - set lower "sanity limit" to 30 seconds. After 3 failed renew attempts, switch to rebind. After this change, we can have more flexible choice of when to do the first renew - does not need to be equal to lease / 2. function old new delta udhcpc6_main 2568 2576 +8 .rodata 103339 103294 -45 udhcpc_main 2609 2550 -59 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/2 up/down: 8/-104) Total: -96 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>	2021-05-01 12:23:25 +02:00

Russell Senior	1c461df70a	udhcpc: ignore zero-length DHCP options Discovered that the DHCP server on a TrendNet router (unknown model) provides a zero-length option 12 (Host Name) in the DHCP ACK message. This has the effect of causing udhcpc to drop the rest of the options, including option 51 (IP Address Lease Time), 3 (Router), and 6 (Domain Name Server), most importantly leaving the OpenWrt device with no default gateway. The TrendNet behavior violates RFC 2132, which in Section 3.14 declares that option 12 has a minimum length of 1 octet. It is perhaps not a cosmic coincidence that I found this behavior on Pi Day. This patch allows zero length options without bailing out, by simply skipping them. function old new delta udhcp_scan_options 183 172 -11 Signed-off-by: Russell Senior <russell@personaltelco.net> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>	2021-03-16 11:40:19 +01:00
