Pablo Neira Ayuso says: ==================== Netfilter fixes for net Patch #1 restores NFPROTO_INET with nft_compat, from Ignat Korchagin. Patch #2 fixes an issue with bridge netfilter and broadcast/multicast packets. There is a day 0 bug in br_netfilter when used with connection tracking. Conntrack assumes that an nf_conn structure that is not yet added to hash table ("unconfirmed"), is only visible by the current cpu that is processing the sk_buff. For bridge this isn't true, sk_buff can get cloned in between, and clones can be processed in parallel on different cpu. This patch disables NAT and conntrack helpers for multicast packets. Patch #3 adds a selftest to cover for the br_netfilter bug. netfilter pull request 24-02-29 * tag 'nf-24-02-29' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: selftests: netfilter: add bridge conntrack + multicast test case netfilter: bridge: confirm multicast packets before passing them up the stack netfilter: nf_tables: allow NFPROTO_INET in nft_(match/target)_validate() ==================== Link: https://lore.kernel.org/r/20240229000135.8780-1-pablo@netfilter.org Signed-off-by: Paolo Abeni <pabeni@redhat.com>
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.
