Pablo Neira Ayuso says: ==================== Netfilter fixes for net This patch contains two late Netfilter's flowtable fixes for net: 1) Flowtable GC pushes back packets to classic path in every GC run, ie. every second. This is because NF_FLOW_HW_ESTABLISHED is only used by sched/act_ct (never set) and IPS_SEEN_REPLY might be unset by the time the flow is offloaded (this status bit is only reliable in the sched/act_ct datapath). 2) sched/act_ct logic to push back packets to classic path to reevaluate if UDP flow is unidirectional only applies if IPS_HW_OFFLOAD_BIT is set on and no hardware offload request is pending to be handled. From Vlad Buslov. These two patches fixes two problems that were introduced in the previous 6.5 development cycle. * tag 'nf-23-10-25' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: net/sched: act_ct: additional checks for outdated flows netfilter: flowtable: GC pushes back packets to classic path ==================== Link: https://lore.kernel.org/r/20231025100819.2664-1-pablo@netfilter.org 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.
