Andrei Matei says: ==================== bpf: fix accesses to uninit stack slots Fix two related issues issues around verifying stack accesses: 1. accesses to uninitialized stack memory was allowed inconsistently 2. the maximum stack depth needed for a program was not always maintained correctly The two issues are fixed together in one commit because the code for one affects the other. V4 to V5: - target bpf-next (Alexei) V3 to V4: - minor fixup to comment in patch 1 (Eduard) - C89-style in patch 3 (Andrii) V2 to V3: - address review comments from Andrii and Eduard - drop new verifier tests in favor of editing existing tests to check for stack depth - append a patch with a bit of cleanup coming out of the previous review ==================== Link: https://lore.kernel.org/r/20231208032519.260451-1-andreimatei1@gmail.com Signed-off-by: Andrii Nakryiko <andrii@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.
