Comments
Hi, thanks to watching my repository.
So, I think you can build with these commands.

Hi @jollaman999 thanks for your reply, i have not success running your commands build, i got this:
|
@figuibej Oh, sorry. It looks like AX-55 uses src-rt-5.04axhnd.675x and not src-rt-5.02axhnd.675x. |
OK @jollaman999 keep me up to date on this when you have some news |
…id_dst() When we try to transmit an skb with md_dst attached through wireguard we hit a null pointer dereference in wg_xmit() due to the use of dst_mtu() which calls into dst_blackhole_mtu() which in turn tries to dereference dst->dev. Since wireguard doesn't use md_dsts we should use skb_valid_dst(), which checks for DST_METADATA flag, and if it's set, then falls back to wireguard's device mtu. That gives us the best chance of transmitting the packet; otherwise if the blackhole netdev is used we'd get ETH_MIN_MTU.
