Vlad Buslov 6ab9684731 net: sched: don't use tc_action->order during action dump 
[ Upstream commit 4097e9d250 ]

Function tcf_action_dump() relies on tc_action->order field when starting
nested nla to send action data to userspace. This approach breaks in
several cases:

- When multiple filters point to same shared action, tc_action->order field
  is overwritten each time it is attached to filter. This causes filter
  dump to output action with incorrect attribute for all filters that have
  the action in different position (different order) from the last set
  tc_action->order value.

- When action data is displayed using tc action API (RTM_GETACTION), action
  order is overwritten by tca_action_gd() according to its position in
  resulting array of nl attributes, which will break filter dump for all
  filters attached to that shared action that expect it to have different
  order value.

Don't rely on tc_action->order when dumping actions. Set nla according to
action position in resulting array of actions instead.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
