commit a3c4a125ec725cefb40047eb05ff9eafd57830b4 upstream.
We need to allow queuing at least one skb even when skb is
larger than sk->sk_rcvbuf.
The cited commit made a mistake while converting a condition
in netlink_broadcast_deliver().
Let's correct the rmem check for the allow-one-skb rule.
Fixes: ae8f160e7eb24 ("netlink: Fix wraparounds of sk->sk_rmem_alloc.")

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.
