When handling a new recv command, we grab a new rsp resource and check for the queue state being live. In case the queue is not in live state, we simply restore the rsp back to the free list. However in this flow we didn't set rsp->queue yet, so we cannot dereference it. Instead, make sure to initialize rsp->queue (and other rsp members) as soon as possible so we won't reference uninitialized variables.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
