wenxu says: ==================== net/sched: fix over mtu packet of defrag in Currently kernel tc subsystem can do conntrack in act_ct. But when several fragment packets go through the act_ct, function tcf_ct_handle_fragments will defrag the packets to a big one. But the last action will redirect mirred to a device which maybe lead the reassembly big packet over the mtu of target device. The first patch fix miss init the qdisc_skb_cb->mru The send one refactor the hanle of xmit in act_mirred and prepare for the third one The last one add implict packet fragment support to fix the over mtu for defrag in act_ct. ==================== Link: https://lore.kernel.org/r/1606276883-6825-1-git-send-email-wenxu@ucloud.cn 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.
