So, some more research: it looks like the R_ARM_THM_JUMP11 symbol is actually wg_packet_send_staged_packets, a boring C function with nothing fancy about it. That github issue you pointed to suggested that it might have something to do with complex crypto functions, but it looks like that's not the case. wg_packet_send_staged_packets is plain old boring C.
But there is one interesting thing about wg_packet_send_staged_packets: it's defined in send.c, and called from send.c, receive.c, device.c, and netlink.c -- four places. What I suspect is happening is that the linker can't quite figure out how to order the functions in the final executable so that the wg_packet_send_staged_packets definition is sufficiently close to all of its call sites, so it then needs to add that extra trampoline midway to get to it. Stupid linker. I'm playing now if there's some manual reordering I can do in the build system so that this isn't a problem, but I'm not very optimistic that I'll succeed. _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
