[PATCH] batman-adv: Disable CONFIG_BATMAN_ADV_SYSFS by default

by Sven Eckelmann

The sysfs support in batman-adv is deprecated since a while and will be removed completely next year. All tools which were known to the batman-adv development team are supporting the batman-adv netlink interface since a while. Thus disabling CONFIG_BATMAN_ADV_SYSFS by default should not cause problems on most systems. It is still possible to enable it in case it is still required in a specific setup.

[B.A.T.M.A.N.] batman-adv and/or batmand porting effort to FreeBSD

by Mahdi Mokhtari

Hi, After some time of playing with the B.A.T.M.A.N protocol and net-interface on OpenWRT and Debian I was thinking to use it with the servers I use everyday (and maybe on routers/appliances I have nanoBSD on). So I started an effort... (As a background) I already ported some applications to FreeBSD [and I'm maintaining them] and also I did work already on the Linux emulation layer of FreeBSD (FreeBSD has a Linux syscall-emulation and Linux-KPI layers). So my approach (as naturally I didn't expect the build of batman-adv.ko to be successful as is), was based on the approach that we [at FreeBSD] did to port Linux's drm... <https://github.com/FreeBSDDesktop/kms-drm> I ended up in adding some header-files to FreeBSD Linux-KPI (like average.h, percpu.h, ...). Now I'm at a state that Netlink blocks me and I'm to determine next step :-) [Which I don't assume it being trivial with my current approach] So I'd like to ask: 1- Is it better approach to "rewrite" batman-adv.ko [at least Netlink-ish (let's call "Linuxism") parts] than what I'm doing now? 2- Any other efforts are being done out there? 3- is batmand deprecated [So I should mainly focus on batman-adv.ko]? 4- any other comments do you have? :D P.S. sorry if I'm not really good at starting conversation from scratch and out-of-nowhere :D but I hope by continuing the collaboration we can have better (more enriched) FreeBSD and better (as in more portable) B.A.T.M.A.N :-) -- Best regards, MMokhi.

[PATCH] batman-adv: Replace FIELD_SIZEOF with sizeof_field

by Sven Eckelmann

The prefered way of getting the size of a member of a struct is the common macro sizeof_field from stddef.h and not the FIELD_SIZEOF (with multiple definitions).
