[ Upstream commit e0b6648b0446e59522819c75ba1dcb09e68d3e94 ]
In theory, dumpreset may fail and invalidate the preceeding log message.
Fix this and use the occasion to prepare for object reset locking, which
benefits from a few unrelated changes:
* Add an early call to nfnetlink_unicast if not resetting which
effectively skips the audit logging but also unindents it.
* Extract the table's name from the netlink attribute (which is verified
via earlier table lookup) to not rely upon validity of the looked up
table pointer.
* Do not use local variable family, it will vanish.
Fixes: 8e6cf365e1 ("audit: log nftables configuration change events")

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.
