Florian Westphal says: ==================== netfilter updates for net Three late fixes for netfilter: 1) If nf_queue user requests packet truncation below size of l3 header, we corrupt the skb, then crash. Reject such requests. 2) add cond_resched() calls when doing cycle detection in the nf_tables graph. This avoids softlockup warning with certain rulesets. 3) Reject rulesets that use nftables 'queue' expression in family/chain combinations other than those that are supported. Currently the ruleset will load, but when userspace attempts to reinject you get WARN splat + packet drops. * git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: netfilter: nft_queue: only allow supported familes and hooks netfilter: nf_tables: add rescheduling points during loop detection walks netfilter: nf_queue: do not allow packet truncation below transport header offset ==================== Link: https://lore.kernel.org/r/20220726192056.13497-1-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 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.
