The ct_state validate should not only check the mask bit and also check mask_bit & key_bit.. For the +new+est case example, The 'new' and 'est' bits should be set in both state_mask and state flags. Or the -new-est case also will be reject by kernel. When Openvswitch with two flows ct_state=+trk+new,action=commit,forward ct_state=+trk+est,action=forward A packet go through the kernel and the contrack state is invalid, The ct_state will be +trk-inv. Upcall to the ovs-vswitchd, the finally dp action will be drop with -new-est+trk.

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.
