OpenWRT 23.05.x SDK fails to build mac80211 due to genlmsg_multicast_allns argument mismatch

For Developers
1

The issue has already been created.

Building mac80211 in OpenWRT SDK 23.05.x fails due to a mismatch in the function signature of genlmsg_multicast_allns . It appears that backports-6.1.110-1 is incompatible with the current kernel headers in OpenWRT 23.05.x.

Steps to reproduce

  1. Download and extract OpenWRT SDK for 23.05.5 (ath79, but likely affects all targets).
  2. Run:

./scripts/feeds update -a
./scripts/feeds install -a
make defconfig
make package/mac80211/compile V=sc

  1. The build fails with the following error:
error: too few arguments to function 'genlmsg_multicast_allns'

Do you mean the ath79 image builder?

No, I mean exactly SDK, which builds only packages, not images.

https://downloads.openwrt.org/releases/23.05.5/targets/ath79/mikrotik/openwrt-sdk-23.05.5-ath79-mikrotik_gcc-12.3.0_musl.Linux-x86_64.tar.xz

You can try any of 23.05.x

Yep I repro this... i'm investigating... it's strange...

Ok problem identified... it's a mix of thing but we we can handle this!

please test... need to wait additional feedback for this. Once it's accepted I will backport to stable branch. To test you can apply this patch to the sdk manually in the feeds/base directory
