I’m working to add WireGuard support to an embedded distro that runs on a mix of x86 and ARM hardware. I’m using 4.19.7 as the kernel base, cross compiling using a well proven toolchain and build-system. The kernel defconfig can be seen here:
https://github.com/chewitt/LibreELEC.tv/blob/amlogic/projects/Amlogic/linux/linux.aarch64.conf I see no compile errors when building the kernel module or wireguard tools. The kernel module loads without errors and ‘wg’ can generate private and preshared keys, but when creating a public key from the private key ‘wg pubkey < /path/to/privatekey' fails with “Bus error” and no key is generated. dmesg from the device after the failure: http://ix.io/1vrb modinfo wireguard filename: /lib/modules/4.19.7/kernel/net/wireguard/wireguard.ko alias: net-pf-16-proto-16-family-wireguard alias: rtnl-link-wireguard version: 0.0.20181119 author: Jason A.

Can you spot the problem? Any suggestions? Christian _______________________________________________ WireGuard mailing list [email protected] https://lists.zx2c4.com/mailman/listinfo/wireguard
