The motivation came from the recent experience of trying to bump cake on openwrt 17.01.5 where I forgot about and fell into the trap that kernel/kmod packages stay at the tagged released version…even if the kmod package is bumped, but the userspace utilities assume backwards compatibility even if bumped and get rebuilt on a frequent basis. Of course our recent upstreaming cake efforts led to a number of ABI ‘tweaks’, which now should I hope basically stop…. or change in backward compatible way. > > If you do want to go the kernel patch route, it's a matter of figuring > out which patches you'll need to add to the backport series.

It looks to me that there are quite a few large changes in this area so have run away for the moment :-) Curiously the openwrt kernel is built without builtin conntrack support, it being added as a module..

As you say, the problem is self limiting given time. > > -Toke Cheers, Kevin D-B 012C ACB2 28C6 C53E 9775 9123 B3A2 389B 9DE2 334A
