Florian Westphal says: ==================== net: flow dissector: allow explicit passing of netns Change since last version: fix kdoc comment warning reported by kbuild robot, no other changes, thus retaining RvB tags from Eric and Willem. v1: https://lore.kernel.org/netdev/20240607083205.3000-1-fw@strlen.de/ Years ago flow dissector gained ability to delegate flow dissection to a bpf program, scoped per netns. The netns is derived from skb->dev, and if that is not available, from skb->sk. If neither is set, we hit a (benign) WARN_ON_ONCE(). This WARN_ON_ONCE can be triggered from netfilter. Known skb origins are nf_send_reset and ipv4 stack generated IGMP messages. Lets allow callers to pass the current netns explicitly and make nf_tables use those instead. This targets net-next instead of net because the WARN is benign and this is not a regression. ==================== Link: https://lore.kernel.org/r/20240608221057.16070-1-fw@strlen.de 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 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.
