Hou Tao says: ==================== Check the remaining info_cnt before repeating btf fields From: Hou Tao <houtao1@huawei.com> Hi, The patch set adds the missed check again info_cnt when flattening the array of nested struct. The problem was spotted when developing dynptr key support for hash map. Patch #1 adds the missed check and patch #2 adds three success test cases and one failure test case for the problem. Comments are always welcome. Change Log: v2: * patch #1: check info_cnt in btf_repeat_fields() * patch #2: use a hard-coded number instead of BTF_FIELDS_MAX, because BTF_FIELDS_MAX is not always available in vmlinux.h (e.g., for llvm 17/18) v1: https://lore.kernel.org/bpf/20240911110557.2759801-1-houtao@huaweicloud.com/T/#t ==================== Link: https://lore.kernel.org/r/20241008071114.3718177-1-houtao@huaweicloud.com 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 reStructuredText 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.
