In rds_bind(), an rds_sock is added to the RDS bind hash table before rs_transport is set. This means that the socket can be found by the receive code path when rs_transport is NULL. And the receive code path de-references rs_transport for congestion update check. This can cause a panic. An rds_sock should not be added to the bind hash table before all the needed fields are set.

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.
