Denys Vlasenko	274ce6cce1	udhcpc: revert deprecation message for -V "-x vendor:VENDOR" will not be a trivial replacement of it: (1) by default, we do send a vendor string ("udhcp BB_VER"), will need code to preserve the default. (2) -V '' currently disables vendor string. -x vendor:'' would not easily achieve that: it adds no option at all (string options can't be empty), and default (1) would trigger. To avoid that, we will need yet another hack to detect -x vendor:'' and interpret that as "no vendor string at all".

Seth David Schoen	5a3d3b8055	udhcpd: don't hardcode treating .0 and .255 specially Even following current Internet standards, it can be perfectly legitimate to issue IPv4 addresses that end in .0 or .255 via DHCP -- this can happen whenever the network is larger than /8. For example, 10.3.4.0 and 10.3.4.255 are legitimate host addresses in 10/8 or 10.3/16. (We also want to be able to issue .0 addresses in smaller networks following our proposed kernel patch and standards changes.) This behavior is already fully controllable by the user, simply by setting start_ip and end_ip correctly. Users who don't want to issue .0 or .255 should set start_ip greater than .0 or end_ip less than .255 and udhcpd will already respect these bounds. (This is also the case for other DHCP servers -- the recommended example configurations will default to a lower bound starting with .1 or some other value, which is typically appropriate, but the user is still allowed to change this to .0 -- or to a range that overlaps a .0 or .255 address -- if so desired.)

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
