Thanks for the patches.
I've only looked at the test querier for a second and I am a little bit
confused that you access things like attrs[BATADV_ATTR_ALGO_NAME] without
checking if this is available or that the received message is valid (according
to the nla_parse policy).
I know that this is only a PoC but wanted to mention it in case somebody wants
to use it as reference for a batctl/alfred implementation.
I like that the netlink interface doesn't introduce complex structs at the
moment (but I have to think a little bit about it). The unnamed enums freak me
out a little bit (names would be nice so it is easier to write kernel-doc for
it).
I just ran the build_test stuff through your branch so you get an early
feedback about some common problems. See the attached mail (the unused symbols
seem to be only symptoms of the build failures with old kernels < 3.12).
Kind regards,
Sven

Thanks for the patches.
I've only looked at the test querier for a second and I am a little bit
confused that you access things like attrs[BATADV_ATTR_ALGO_NAME] without
checking if this is available or that the received message is valid (according
to the nla_parse policy).
I know that this is only a PoC but wanted to mention it in case somebody wants
to use it as reference for a batctl/alfred implementation.
I like that the netlink interface doesn't introduce complex structs at the
moment (but I have to think a little bit about it). The unnamed enums freak me
out a little bit (names would be nice so it is easier to write kernel-doc for
it).
I just ran the build_test stuff through your branch so you get an early
feedback about some common problems. See the attached mail (the unused symbols
seem to be only symptoms of the build failures with old kernels < 3.12).
Kind regards,
Sven
