Move the custom ASK/NXP kernel build from lf-6.18.2-1.0.0 toward
the upstream stable 6.18.y baseline, currently 6.18.30.
This pulls in upstream stable fixes, including the BPF verifier fix needed
by Cilium. The previous 6.18.2-based kernel triggered:
verifier bug: REG INVARIANTS VIOLATION (false_reg1)
reg_bounds_sanity_check()
bpf_prog_load()
cilium-agent
The issue is no longer reproduced on 6.18.30 after fresh boot:
Cilium 1.19.2 reports healthy, BPF datapath is active, all controllers are
healthy, cluster health is reachable, and dmesg no longer shows the verifier
warning.
Refresh affected ASK upstream patch splits:
- add bridge br_input patch
- refresh xfrm policy/state patches
- update package/kernel build inputs for 6.18.30
