Kumar Kartikeya Dwivedi says: ==================== When iterating over modifiers, ensure that type tags can only occur at head of the chain, and don't occur later, such that checking for them once in the start tells us there are no more type tags in later modifiers. Clang already ensures to emit such BTF, but user can craft their own BTF which violates such assumptions if relied upon in the kernel. Changelog: ---------- v2 -> v3 v2: https://lore.kernel.org/bpf/20220418224719.1604889-1-memxor@gmail.com * Address nit from Yonghong, add Acked-by v1 -> v2 v1: https://lore.kernel.org/bpf/20220406004121.282699-1-memxor@gmail.com * Fix for bug pointed out by Yonghong * Update selftests to include Yonghong's example ==================== Signed-off-by: Alexei Starovoitov <ast@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.
