Libhogweed for Unikraft

This is the port of nettle's libhogweed for Unikraft as external library.

Libhogweed depends on newlib, so please make sure you add the following line to the LIBS variable in your Makefile: ...:$(UK_LIBS)/newlib:$(UK_LIBS)/libhogweed:...

Testing

For running the tests: enable the testsuite option in the configuration menu and select the desired tests. Make sure to include testutils_glue.h and call the run_all_libhogweed_tests(v); function in your main application. The parameter v stands for verbose and you can either set it to 0, non verbose mode, or 1, verbose mode.

Applications

To run an application that requires a filesystem, you'll need to run them on kvm and enable 9pfs, selecting the following menu options, all of them under Library Configuration:

  • libnewlib
  • libhogweed
  • vfscore: VFS Core Interface ---> vfscore: Configuration ---> Automatically mount a root filesystem ---> Default root filesystem ---> 9PFS
  • uk9p: 9p client
  • 9pfs: 9p filesystem
  • devfs: devfs file system ---> Mount /dev during boot
  • ukswrand: Software random number generator ---> Register random and urandom device to devfs

Mounting a file system

In order to mount the file system you'll need to provide the following Qemu parameters:

  • -fsdev local,id=myid,path=<some directory>,security_model=none
  • -device virtio-9p-pci,fsdev=myid,mount_tag=rootfs,disable-modern=on, disable-legacy=off

Note that if you use a different mount_tag, you'll need to add it in Default root device in vfscore configuration. Also, to provide command line arguments to the kernel, you'll need to use -append "param1 param2 ...".

Please refer to the README.md as well as the documentation in the doc/ subdirectory of the main unikraft repository.
