Hou Tao says: ==================== From: Hou Tao <houtao1@huawei.com> Hi, The patchset constitues three fixes for bpf map iterator: (1) patch 1~4: fix user-after-free during reading map iterator fd It is possible when both the corresponding link fd and map fd are closed bfore reading the iterator fd. I had squashed these four patches into one, but it was not friendly for stable backport, so I break these fixes into four single patches in the end. Patch 7 is its testing patch. (2) patch 5: fix invalidity check for values in sk local storage map Patch 8 adds two tests for it. (3) patch 6: reject sleepable program for non-resched map iterator Patch 9 add a test for it. Please check the individual patches for more details. And comments are always welcome. Regards, Tao Changes since v2: * patch 1~6: update commit messages (from Yonghong & Martin) * patch 7: add more detailed comments (from Yonghong) * patch 8: use NULL directly instead of (void *)0 v1: https://lore.kernel.org/bpf/20220806074019.2756957-1-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 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.
