[ Upstream commitf5e85ce8e7] Since commitbc7d811ace("netfilter: nf_ct_h323: Convert CHECK_BOUND macro to function"), NAT traversal for H.323 doesn't work, failing to parse H323-UserInformation. nf_h323_error_boundary() compares contents of the bitstring, not the addresses, preventing valid H.323 packets from being conntrack'd. This looks like an oversight from when CHECK_BOUND macro was converted to a function. To fix it, stop dereferencing bs->cur and bs->end.

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.
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.
