Ilia.Gavrilov 1d2ab3d438 netfilter: nf_conntrack_sip: fix the ct_sip_parse_numerical_param() return value.
[ Upstream commit f188d30087480eab421cd8ca552fb15f55d57f4d ]

ct_sip_parse_numerical_param() returns only 0 or 1 now.
But process_register_request() and process_register_response() imply
checking for a negative value if parsing of a numerical header parameter
failed.
The invocation in nf_nat_sip() looks correct:
 	if (ct_sip_parse_numerical_param(...) > 0 &&
 	    ...) { ... }

Make the return value of the function ct_sip_parse_numerical_param()
a tristate to fix all the cases
a) return 1 if value is found; *val is set
b) return 0 if value is not found; *val is unchanged
c) return -1 on error; *val is undefined

Found by InfoTeCS on behalf of Linux Verification Center
(linuxtesting.org) with SVACE.

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.
