Subject: problems with udp header compression
Date: Thu, 30 Oct 2014 09:42:55 +0000 [thread overview]
Message-ID: <5452081F.5090706@xsilon.com> (raw)
I think I have stumbled across a bug in the udp header compression or
possibly in a higher layer of the network stack.
If I send a UDP message using a RAW socket[0] the src and dest port
numbers get corrupted on 802.15.4 devices. This does not occur on ethernet.
If I print out the udp source and destination ports in
compress_udp_header they are incorrect. The function udp_hdr is not
pointing at the udp header but actually the ip6 header.
If I send a UDP message using a normal UDP socket I do not have this
problem.
Any ideas?
Simon
