Ensure that no further socket reads occur after a receive processing error, either from io_work being re-scheduled or nvme_tcp_poll. Failing to do so can result in unrecognised PDU payloads or TCP stream garbage being processed as a C2H data PDU, and potentially start copying the payload to an invalid destination after looking up a request using a bogus command id.

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.
