Project Description

The Linux Test Project has a solid and strong code base which could be used to create a generic testing framework. The new testing framework might be used by users in order to test their own C code, taking advantage of the LTP features, from test macros to test declaration, plus many other features.

The idea is to see what's the complexity needed to get rid of the LTP specific code and to create a simple prototype with all needed features.

Cleaned up the entire LTP folder, removing tests and unused files. Most of the work was focusing on compiling libltp.so library using Makefile. What I seen is that Makefile is a nice build system, but it requires too much effort in terms of scripting, when it comes to switch from autotools. The library was successfully build, but this method requires too much effort.

For this reason, I will try to take a look at other possibilities, such as cmake/meson.

After a few try and discussions with the Kernel QA team, I decided to move into meson, which seems to be the best choice in terms of scripting difficulties and nice results. Let's start to hack!!

First of all, I ported the Makefile used to compile libltp.so into meson, including a meson.build file in the main root. For now it's kinda complex, but I will eventually split it into sub-projects in the next days.

A generic TODO list is the following:

  • build libltp.so/.a
  • generate config.h
  • generate syscalls.h
  • create installation

Meson is the perfect choice to build ltp-core library and I already wrote the code to create config.h, which was actually the most difficult task of all, since all the rules defined in configure.ac to check for headers, functions, types and struct members have to be ported one-by-one from autotools to meson. I managed to do it and the result is pretty good, but it was a hard task.

Habemus papam! I was able to generate syscalls.h file, recreating the regen.sh script using python language and calling it from meson build system. The meson subdir structure is not good to force syscalls.h and config.h creation, so I had to split meson.build definitions and populate them inside the sub-project directories. All works and we have the first result :)

The library installation is ready and it can be used via meson install command.

Also current LTP tests can be compiled easily:

``` meson configure -Ddefault_library=static meson install --destdir=ltp

gcc -Iltp/usr/local/include chdir04.c libltp.a -o chdir04

./chdir04

I was able to compile the entire cve testing suite using ltp-core library :-)
