Linux kernel source tree
1f7f31bf72
While the kernel community has been good at maintaining backwards compatibility with kernel UAPIs, it would be helpful to have a tool to check if a commit introduces changes that break backwards compatibility. To that end, introduce check-uapi.sh: a simple shell script that checks for changes to UAPI headers using libabigail. libabigail is "a framework which aims at helping developers and software distributors to spot some ABI-related issues like interface incompatibility in ELF shared libraries by performing a static analysis of the ELF binaries at hand." The script uses one of libabigail's tools, "abidiff", to compile the changed header before and after the commit to detect any changes. abidiff "compares the ABI of two shared libraries in ELF format. It emits a meaningful report describing the differences between the two ABIs." The script also includes the ability to check the compatibility of all UAPI headers across commits. This allows developers to inspect the stability of the UAPIs over time. Signed-off-by: John Moon <quic_johmoo@quicinc.com> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
