- * Userspace API for WireGuard
- * ---------------------------
- *
- * ioctl(WG_GET_DEVICE, { .ifr_name: "wg0", .ifr_data: NULL }):
- *
- *     Returns the number of bytes required to hold the peers of a device (`ret_peers_size`).
- *
- * ioctl(WG_GET_DEVICE, { .ifr_name: "wg0", .ifr_data: user_pointer }):
- *
- *     Retrevies device info, peer info, and ipmask info.
- *
- *     `user_pointer` must point to a region of memory of size `sizeof(struct wgdevice) + ret_peers_size`
- *     and containing the structure `struct wgdevice { .peers_size: ret_peers_size }`.
- *
- *     Writes to `user_pointer` a succession of structs:
- *
- *         struct wgdevice { .num_peers = 3 }
- *             struct wgpeer { .num_ipmasks = 4 }
- *                 struct wgipmask
- *                 struct wgipmask
- *                 struct wgipmask
- *                 struct wgipmask
- *             struct wgpeer { .num_ipmasks = 2 }
- *                 struct wgipmask
- *                 struct wgipmask
- *             struct wgpeer { .num_ipmasks = 0 }
- *
- *     Returns 0 on success. Returns -EMSGSIZE if there is too much data for the size of passed-in
- *     memory, in which case, this should be recalculated using the call above. Returns -errno if
- *     another error occured.
- *
- * ioctl(WG_SET_DEVICE, { .ifr_name: "wg0", .ifr_data: user_pointer }):
- *
- *     Sets device info, peer info, and ipmask info.
- *
- *     `user_pointer` must point to a region of memory containing a succession of structs:
- *
- *         struct wgdevice { .num_peers = 3 }
- *             struct wgpeer { .num_ipmasks = 4 }
- *                 struct wgipmask
- *                 struct wgipmask
- *                 struct wgipmask
- *                 struct wgipmask
- *             struct wgpeer { .num_ipmasks = 2 }
- *                 struct wgipmask
- *                 struct wgipmask
- *             struct wgpeer { .num_ipmasks = 0 }
- *
- *     If `wgdevice->flags & WGDEVICE_REPLACE_PEERS` is true, removes all peers of device before adding new ones.
- *     If `wgpeer->flags & WGPEER_REMOVE_ME` is true, the peer identified by `wgpeer->public_key` is removed.
- *     If `wgpeer->flags & WGPEER_REPLACE_IPMASKS` is true, removes all ipmasks before adding new ones.
- *     If `wgdevice->private_key` is filled with zeros, no action is taken on the private key.
- *     If `wgdevice->preshared_key` is filled with zeros, no action is taken on the preshared key.
- *     If `wgdevice->flags & WGDEVICE_REMOVE_PRIVATE_KEY` is true, the private key is removed.
- *     If `wgdevice->flags & WGDEVICE_REMOVE_PRESHARED_KEY` is true, the preshared key is removed.
- *
- *     Returns 0 on success, or -errno if an error occurred.
