Jakub Kicinski dc7769244e tcp_ipv6: set the drop_reason in the right place 
Looks like the IPv6 version of the patch under Fixes was
a copy/paste of the IPv4 but hit the wrong spot.
It is tcp_v6_rcv() which uses drop_reason as a boolean, and
needs to be protected against reason == 0 before calling free.
tcp_v6_do_rcv() has a pretty straightforward flow.

The resulting warning looks like this:
  WARNING: CPU: 1 PID: 0 at net/core/skbuff.c:775
  Call Trace:
    tcp_v6_rcv (net/ipv6/tcp_ipv6.c:1767)
    ip6_protocol_deliver_rcu (net/ipv6/ip6_input.c:438)
    ip6_input_finish (include/linux/rcupdate.h:726)
    ip6_input (include/linux/netfilter.h:307)

Fixes: f8319dfd1b ("net: tcp: reset 'drop_reason' to NOT_SPCIFIED in tcp_v{4,6}_rcv()")

README 

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.
