Adds a gnrc_netif specific rawmode flag to indicate that the netdev
device is configured in raw mode. This flag is kept in sync with a
possible flag in the netdev device and should only be modified via the
setter call.
gnrc_sock_recv used to duplicate functionality of gnrc_ipv6_get_header,
but additionally checked whether the IPv6 snip is large enough.
All checks are now included in gnrc_ipv6_get_header, but as most of them
stem from programming / user errors, they were moved into asserts; this
constitutes an API change.
For CoAP, there is actually a difference between
`/some/path` and `/some/path/`. This needs to be reflected
when parsing the URI and location path options from a given
string.
Our `gnrc_minimal` example configures the link-local address from the
IEEE 802.15.4 short address since it does not include 6Lo-ND.
This causes the application to be incompatible with our other GNRC
application that do include 6Lo-ND, since it [assumes][1] the link-local
address to be based on the EUI-64 for address resolution.
This enforces long addresses (aka EUI-64) for all IEEE 802.15.4 devices
when IPv6 is compiled in so `gnrc_minimal` is compatible again to the
rest.
Fixes#9910
[1]: https://tools.ietf.org/html/rfc6775#section-5.2
- add generic string put and get functions
- add location path and location query options
- add dedicated functions for getting and setting
URI query, URI path, location query, and location path
options
Currently the length of the full ICMPv6 packet is passed to the
validator function causing validation failures on valid packets. This
fixes that by passing the length of remaining RPL options of the packet.
The code originally assumed that the location of DIS struct is directly
after the ICMPv6 struct. This is not necessarily true when both structs
are individually allocated by pktbuf. This commit fixes this issue by
directly accessing the location of the DIS struct.
Linux doesn't have ARO support at the moment so this is a workaround to
try to speak 6Lo-ND while still being able to do DAD with a border
router that doesn't.
