Daniel Lublin	7eb4d0304b	fw: load app at the start of RAM ... Since app is always loaded at the start of RAM, the TK1_APP_ADDR define is no longer needed. Signed-off-by: Daniel Lublin <daniel@lublin.se>	2023-03-14 10:25:03 +01:00

Michael Cardell Widerkrantz	d77654bb8e	fw: No .data or .bss segment ... We don't use any .data or .bss segment at all to keep all the firmware variables in the stack in protected fw_ram. Signed-off-by: Daniel Lublin <daniel@lublin.se>	2023-03-14 10:25:02 +01:00
Michael Cardell Widerkrantz	56e34b3add	fw/testfw: Use fw_ram for firmware stack ... This means firmware's stack shouldn't be accessible to programs running in app_mode. It also means we don't need to take special care of secure_ctx which can now be an ordinary stack variable. Nonetheless we zero out secure_ctx after final use and inline some assembler to zero out the entire fw_ram after use, just before switching to app_mode. Signed-off-by: Daniel Lublin <daniel@lublin.se>	2023-03-14 10:25:02 +01:00
Michael Cardell Widerkrantz	d2240b3e0f	fw: Use a bit string for allowed_commands ... For every state, define a constant bitstring with allowed commands and check incoming command agains that. Signed-off-by: Daniel Lublin <daniel@lublin.se>	2023-03-14 10:25:02 +01:00
Michael Cardell Widerkrantz	8edfdf9c36	fw: Remove state init_loading, introduce state fail ... - We always assert on allowed commands in a state. - We don't allow FW_CMD_LOAD_APP to be used twice. - Enter fail state on read buffer overrun, header endpoint not for us, header parse error, and unknown firmware command. Signed-off-by: Daniel Lublin <daniel@lublin.se>	2023-03-14 10:25:02 +01:00
Michael Cardell Widerkrantz	65f100a3c0	fw: Use byte readable UDS ... UDS is now byte readable (but not writable). Use UDS and USS directly in a blake2s_update() instead of concatenating them into fw_ram. UDS will still live for a short while in fw_ram in the blake2s context buffer but will soon be overwritten. Signed-off-by: Daniel Lublin <daniel@lublin.se>	2023-03-14 10:25:01 +01:00
Michael Cardell Widerkrantz	b34fdbcd37	testfw: Use wordcpy_s() and memcpy_s() ... Use new wordcpy_s() and memcpy_s() functions from lib.c. Add a local memcpy() which compiling with -Os seems to demand. Why? Signed-off-by: Daniel Lublin <daniel@lublin.se>	2023-03-14 10:25:01 +01:00
Michael Cardell Widerkrantz	cc032d9883	fw: Hide HTIF functions better when using NOCONSOLE ... We define macros for them that expand to nothing or to a constant to avoid any extra function calls to dummy functions when running on real hardware with no console.

Michael Cardell Widerkrantz	3a7ec9b9a0	fw: Run forever_redflash() when aborting from asserts ... Should be more vissible than an eternal loop. Signed-off-by: Daniel Lublin <daniel@lublin.se>	2023-03-14 10:25:01 +01:00

Michael Cardell Widerkrantz	ccc3b16569	fw: Safer memory functions + asserts ... Introduce memcpy_s() and wordcpy_s() that takes the destination buffer size as an argument. Use assert() which aborts our program to an eternal loop if we hit problems. Sprinkle asserts elsewhere as well. Signed-off-by: Daniel Lublin <daniel@lublin.se>	2023-03-14 10:25:01 +01:00
