Normally, a socket can not be freed/reused unless all its TX packets left qdisc and were TX-completed. However connect(AF_UNSPEC) allows this to happen. With commitfc59d5bdf1("pkt_sched: fq: clear time_next_packet for reused flows") we cleared f->time_next_packet but took no special action if the flow was still in the throttled rb-tree. Since f->time_next_packet is the key used in the rb-tree searches, blindly clearing it might break rb-tree integrity. We need to make sure the flow is no longer in the rb-tree to avoid this problem.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
