Intrestingly, the problem does not appear when manually building inside a ubuntu 20.04 lxc container. So it must somehow be related to which compiler flags are used during dpkg builds

export DEB_BUILD_MAINT_OPTIONS = hardening=+all,-stackprotector
in
debian/rules works around the problem - but then this means even the host binaries are built without stack smashing protection :/
We would want to enable this selectively for the firmware sub-directory

I did try any combinations of export / variable assignments, but I couldn't get dpkg to build the 'firmware' target with different DEB_BUILD_MAINT_OPTIONS than the host utilitites :/

Hi Harald,
why not to simply add the missing symbols?
The '__stack_chk_guard' is basically a magic value (e.g. 0xdeadbeef), and '__stack_chk_fail' is a user-defined function that will be called if the stack is corrupted. It could basically call osmo_panic().
This code should make the linker happy:
uintptr_t __stack_chk_guard = 0xdeadbeef; // adapt to the word width of your architecture
void __stack_chk_fail(void)
{
osmo_panic("Stack smashing detected!\n");
}
Best regards,
Vadim.
