mausezahn: Increase buffer size for listen address string
Commit 2de653340c ("mausezahn: bind to IP address in interactive mode") introduced mz_listen_addr of size 15 to hold the IP address to bind to. Since an address can be maximum 15 characters long, this doesn't account for the terminating '\0'. Fix this by increasing the buffer size to 16. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

he memory map handling of the stub FDT code, but inadvertently created an issue with such firmware, by moving some of the FDT manipulation to after the invocation of ExitBootServices(). Given that the stub's libfdt implementation uses the ordinary, accelerated string functions, which rely on hardware handling of unaligned accesses, manipulating the FDT with the MMU off may result in alignment faults. So fix the situation by moving the update_fdt_memmap() call into the callback function invoked by efi_exit_boot_services() right before it calls the ExitBootServices() UEFI service (which is arguably a better place for it anyway) Note that disabling the MMU in ExitBootServices() is not compliant with the UEFI spec, and carries great risk due to the fact that switching from cached to uncached memory accesses halfway through compiler generated code (i.e., involving a stack) can never be done in a way that is architecturally safe.
