Pablo Neira Ayuso 7acd9378dc netfilter: nf_flow_table_offload: Correct memcpy size for flow_overload_mangle()
In function 'memcpy',
     inlined from 'flow_offload_mangle' at net/netfilter/nf_flow_table_offload.c:112:2,
     inlined from 'flow_offload_port_dnat' at net/netfilter/nf_flow_table_offload.c:373:2,
     inlined from 'nf_flow_rule_route_ipv4' at net/netfilter/nf_flow_table_offload.c:424:3:
./include/linux/string.h:376:4: error: call to '__read_overflow2' declared with attribute error: detected read beyond size of object passed as 2nd parameter
   376 |    __read_overflow2();
       |    ^~~~~~~~~~~~~~~~~~

The original u8* was done in the hope to make this more adaptable but
consensus is to keep this like it is in tc pedit.

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.
