This patch series adds compression of outgoing IPv6 prefixes to the Babel protocol, and also adds support to the parser for parsing subtlvs as per RFC6126 bis (see https://tools.ietf.org/html/draft-ietf-babel-rfc6126bis-02#section-4.4).
Hi
The subtlv parser looks OK. W.r.t. prefix compression i would prefer if it would be done in the same manner as in the other direction (parsing), i.e. having u8 def_ip6_prefix[16] in network order in babel_write_state and using a memcmp()-like function that returns first differing byte instead of using ip6_common_octets().
+ omit = MIN(omit, + MIN(tlv->plen, net6_pxlen(&state->def_ip6_prefix)) / 8);
Note that MIN() is a macro that expands its arguments two times, so it is not a good idea to nest them.
OK, will fix and resend. Should I just resend that one patch, or would you prefer I resend all three (including the dualstack patch) in a common series?
