I thought the kernel symbols activated some necessary machinery in the kernel, in addition to producing the .ko module. I think I found the cause of the issue: the packages kmod-udptunnel4.ipk and kmod-udptunnel6.ipk are generated, but are empty (no .ko file). When I activate the kernel symbol in kernel_menuconfig, these packages do provide the .ko files as expected. I have attached the empty packages to this email, just in case.

CONFIG_NET_UDP_TUNNEL will create ip6_udp_tunnel.ko which for example has udp_tunnel6_xmit_skb inside it. once all of these are packaged you can make wireguard depend on them.

[LEDE-DEV] Kernel symbol dependencies and KCONFIG usage for kernel packages
Hi, I am packaging a new kernel module (wireguard), the package is currently here [1]. However, I have some trouble understanding what KCONFIG does. Wireguard needs a few kernel options, so I thought that KCONFIG was the place to declare such dependencies: https://github.com/zorun/packages-1/blob/wireguard/net/wireguard/Makefile#L90 However, it does not seem to enable these options. The module compiles fine, it installs fine [2], but then it fails to load at runtime: Sat Jul 2 10:04:50 2016 kern.warn kernel: [ 95.015838] wireguard: Unknown symbol udp_sock_create4 (err 0) Sat Jul 2 10:04:50 2016 kern.warn kernel: [ 95.022021] wireguard: Unknown symbol udp_tunnel6_xmit_skb (err 0) Sat Jul 2 10:04:50 2016 kern.warn kernel: [ 95.028767] wireguard: Unknown symbol udp_tunnel_sock_release (err 0) Sat Jul 2 10:04:50 2016 kern.warn kernel: [ 95.035570] wireguard: Unknown symbol setup_udp_tunnel_sock (err 0) Sat Jul 2 10:04:50 2016 kern.warn kernel: [ 95.042136] wireguard: Unknown symbol udp_sock_create6 (err 0) Sat Jul 2 10:04:50 2016 kern.warn kernel: [ 95.048297] wireguard: Unknown symbol udp_tunnel_xmit_skb (err 0) It works when selecting the needed options manually in kernel_menuconfig, but it's a huge pain. Is there a way to get the needed kernel options automatically? Maybe this only happens for packages that are part of the core Lede distribution?
