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.

The bounds checking for the arguments accessed in the BPF program breaks when the expected_attach_type is not BPF_TRACE_FEXIT, BPF_LSM_MAC or BPF_MODIFY_RETURN resulting in no check being done for the default case (the programs which do not receive the return value of the attached function in its arguments) when the index of the argument being accessed is equal to the number of arguments (nr_args). This was a result of a misplaced "else if" block introduced by the Commit 6ba43b76 ("bpf: Attachment verification for BPF_MODIFY_RETURN") Fixes: 6ba43b76 ("bpf: Attachment verification for BPF_MODIFY_RETURN") Reported-by:Jann Horn <jannh@google.com> Signed-off-by:
