The upcoming support for LUKS2 encryption will require a JSON parser to
decode all parameters required for decryption of a drive. As there is
currently no other tool that requires JSON, and as gnulib does not
provide a parser, we need to introduce a new one into the code base. The
backend for the JSON implementation is going to be the jsmn library [1].
It has several benefits that make it a very good fit for inclusion in
GRUB:
- It is licensed under MIT.
- It is written in C89.
- It has no dependencies, not even libc.
- It is small with only about 500 lines of code.
- It doesn't do any dynamic memory allocation.
- It is testen on x86, amd64, ARM and AVR.
The library itself comes as a single header, only, that contains both
declarations and definitions. The exposed interface is kind of
simplistic, though, and does not provide any convenience features
whatsoever. Thus there will be a separate interface provided by GRUB
around this parser that is going to be implemented in the following
commit. This change only imports jsmn.h from tag v1.1.0 and adds it
unmodified to a new json module with the following command:
curl -L https://raw.githubusercontent.com/zserge/jsmn/v1.1.0/jsmn.h \
-o grub-core/lib/json/jsmn.h
