When an ICMP or ICMPV6 error is received, the error will be attached to the socket (sk_err) and the report function will get called. Clear any pending error here by calling sock_error(). This would cause the following attempt to use the socket to fail with the error code stored by the ICMP error, resulting in unexpected errors with various side effects depending on the context.

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.
