strp_parser_err is called with a negative code everywhere, which then
calls abort_parser with a negative code. strp_msg_timeout calls
abort_parser directly with a positive code. Negate ETIMEDOUT
to match signed-ness of other calls.
The default abort_parser callback, strp_abort_strp, sets
sk->sk_err to err. Also negate the error here so sk_err always
holds a positive value, as the rest of the net code expects. Currently
a negative sk_err can result in endless loops, or user code that
thinks it actually sent/received err bytes.
Found while testing net/tls_sw recv path.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
