2021-06-05udhcpc: revert deprecation message for -VDenys Vlasenko
"-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". IOW: removing -V is likely to increase code size, not decrease. function old new delta udhcpc_main 2563 2555 -8 .rodata 103251 103198 -53 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/2 up/down: 0/-61) Total: -61 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-06-03udhcpd: don't hardcode treating .0 and .255 speciallySeth David Schoen
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.)

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>
