[Kea-users] KEA handling malformed packets

[Marcin Jurczuk]

Francis,
I did experiment loaded bootp hook and it worked with following DEBUG
message:
kea4  | DEBUG BOOTP_PACKET_OPTIONS_SKIPPED an error unpacking an option,
caused subsequent options to be skipped: Option parse failed. Tried to
parse 161 bytes from 158-byte long buffer.
However rest of processing was succeded and device became online.

Is this something stable, that can be trusted to work with on some
production environment ?

Thanks!
