Currently, on MP_JOIN failure we reset the child socket, but leave the request socket untouched. tcp_check_req will deal with it according to the 'tcp_abort_on_overflow' sysctl value - by default the req socket will stay alive. The above leads to inconsistent behavior on MP JOIN failure, and bad listener overflow accounting. This patch addresses the issue leveraging the infrastructure just introduced to ask the TCP stack to drop the req on failure. The child socket is not freed anymore by subflow_syn_recv_sock(), instead it's moved to a dead state and will be disposed by the next sock_put done by the TCP stack, so that listener overflow accounting is not affected by MP JOIN failure.

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.
