This is the port of keyutils 1.6 for Unikraft as external library.
keyutils depends on libc(e.g. newlib), so please ensure you add the following line to the LIBS variable in the Makefile:
...$(UK_LIBS)/libkeyutils:$(UK_LIBS)/newlib...
Before you proceed to writing your own application, you can use the keyctl program from keyutils by enabling it in the configuration menu.
Please refer to the README.md as well as the documentation in the doc/
subdirectory of the main unikraft repository.
