Florian Westphal 66293c46c9 netfilter: nf_tables: delay chain policy update until transaction is complete
When we process a long ruleset of the form

chain input {
   type filter hook input priority filter; policy drop;
   ...
}

Then the base chain gets registered early on, we then continue to
process/validate the next messages coming in the same transaction.

Problem is that if the base chain policy is 'drop', it will take effect
immediately, which causes all traffic to get blocked until the
transaction completes or is aborted.

Fix this by deferring the policy until the transaction has been
processed and all of the rules have been flagged as active.

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.
