d686a045c8 safe_strtoXX interface proved to be a bit unconvenient. 
Remove it, introduce saner bb_strtoXX.

3f78561d63 My first bout of untangling udhcp. Make lots of gratuitous #defines go 
away, substitutie BB_VER for an external VERSION, use busybox CONFIG symbols
rather than checking for them then defining others, etc.  Lots more cleanup
to do...

Hello,

Here's a patch for a first attempt at static leases for udhcpd.
Included in the tarball are 2 files (static_leases.c, static_leases.h)
and a patch against the latest cvs.

In the config file you can configure static leases with the following
format:

static_lease 00:60:08:11:CE:4E 192.168.0.54
static_lease 00:60:08:11:CE:3E 192.168.0.44

Comments/suggestions/improvements are welcome.

8f43126934 not sure who made this change, but it certainly mucks things up (note 'fwrite(leases, ...'), adds a bit more code, and some stack overhead. Anywho, this fixes it, and retains the spirit of what the submitter of this change was attempting to acheive (the entire lease is written at once in a struct) 2003-12-16 01:29:40 +00:00
