[ Upstream commit839349d139] On the remote side, when QRTR socket is removed, af_qrtr will call qrtr_port_remove() which broadcasts the DEL_CLIENT packet to all neighbours including local NS. NS upon receiving the DEL_CLIENT packet, will remove the lookups associated with the node:port and broadcasts the DEL_SERVER packet. But on the host side, due to the arrival of the DEL_CLIENT packet, the NS would've already deleted the server belonging to that port. So when the remote's NS again broadcasts the DEL_SERVER for that port, it throws below error message on the host: "failed while handling packet from 2:-2" So fix this error by not broadcasting the DEL_SERVER packet when the DEL_CLIENT packet gets processed."

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.
