Add void to function signatures meant to be used without args 2024-03-19 08:41:39 +01:00

Change memory constants to defines 
Instead of putting  memory constant into an enum we use defines.

Use the direct memory address instead of ORing constants together to
compute the address.

An enum in ISO C is a signed int. Some of are memory addresses are to
large to fit in a signed int. This is not a problem since we're not
using ISO C (-std=gnu99) but it doesn't look very nice if you turn on
pedantic warnings. Also, if someone would use another compiler which
at least supports the inline assembly we use, but possible not other
GNU extensions, things would probably break.

Since UDS is not byte-readable we copy it by word to local_uds. Now
UDS lives for a short while in local_uds on the stack in FW_RAM and in
the internal buffer of the blake2s context (also in FW_RAM) but is
very soon overwritten.

fw: clang-tidy and splint: New make target: check 
Add clang-tidy and splint static analytics check. For now, we use only
the cert-* warnings on clang-tidy and run splint with a lot of flags
to allow more things.

Changes to silence these analytics:

- Stop returning stuff from our debug print functions. We don't check
  them anyway and we don't have any way of detecting transmission
  failure.

- Declare more things static that isn't used outside of a file.

- Change types to be more consistent, typically to size_t or
  something or to uint32_t.

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.

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.

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.

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?

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.
