Hi,
I recently spent some time digging into what's needed for proper eBPF
build support in OpenWrt. Here's what I found so far:
Most out-of-tree eBPF based projects fork some of the BPF related kernel
headers from various different kernel versions and manually maintain
those forks. These header

Hi Felix,
I'd suggest to require a preinstalled host toolchain for the time being.

retch, but I am under the impression there will
be cases where this can be desirable.
My 2 cents only.

Hiho,
Thx for the nice summary!
From my more admin, testing, running Mesh network perspective on OpenWrt I
would prefer option 4)
Reasons:
-eBPF filters running in OpenWrt should be a reviewed process overseen by the
core team
-the CO-RE concept with userspace scripting for mature eBPF filters

If we rely on the toolchain on the host, the builds might var

I wouldn't make it dependent on whether openwrt compiles on the buildbot
or not.
