Linux kernel source tree

Not sure why this special case exists. Early drop logic (which kicks in when conntrack table is full) should be independent of flowtable offload and only consider assured bit (i.e., two-way traffic was seen). flowtable entries hold a reference to the conntrack entry (struct nf_conn) that has been offloaded. The conntrack use count is not decremented until after the entry is free'd. This change therefore will not result in exceeding the conntrack table limit. It does allow early-drop of tcp flows even when they've been offloaded, but only if they have been offloaded before syn-ack was received or after at least one peer has sent a fin. Currently 'fin' packet reception already stops offloading, so this should not impact offloading either.

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 reStructuredText 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.
