Add the --post-file option to send form data from a file. As with --post-data it's up to the user to ensure that the data is encoded as appropriate: all wget does is stuff the provided data into the request. The --post-data and --post-file options are mutually exclusive and only one instance of either may be given. Additionally: - update the usage message to include missing details of the --post-data and --header options; - free POST data if FEATURE_CLEAN_UP is enabled. function old new delta packed_usage 34158 34214 +56 wget_main 2762 2805 +43 .rodata 99225 99240 +15 static.wget_longopts 266 278 +12 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 4/0 up/down: 126/0) Total: 126 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

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.)
