Menglong Dong says: ==================== net: skb: introduce kfree_skb_with_reason() In this series patch, the interface kfree_skb_with_reason() is introduced(), which is used to collect skb drop reason, and pass it to 'kfree_skb' tracepoint. Therefor, 'drop_monitor' or eBPF is able to monitor abnormal skb with detail reason. In fact, this series patches are out of the intelligence of David and Steve, I'm just a truck man :/ Previous discussion is here: https://lore.kernel.org/netdev/20211118105752.1d46e990@gandalf.local.home/ https://lore.kernel.org/netdev/67b36bd8-2477-88ac-83a0-35a1eeaf40c9@gmail.com/ In the first patch, kfree_skb_with_reason() is introduced and the 'reason' field is added to 'kfree_skb' tracepoint. In the second patch, 'kfree_skb()' in replaced with 'kfree_skb_with_reason()' in tcp_v4_rcv(). In the third patch, 'kfree_skb_with_reason()' is used in __udp4_lib_rcv(). Changes since v3: - fix some code style problems in skb.h Changes since v2: - rename kfree_skb_with_reason() to kfree_skb_reason() - make kfree_skb() static inline, as Jakub suggested Changes since v1: - rename some drop reason, as David suggested - add the third patch ==================== Link: https://lore.kernel.org/r/20220109063628.526990-1-imagedong@tencent.com Signed-off-by: Jakub Kicinski <kuba@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.
