The ice_alloc_lan_q_ctx function allocates the queue context array for a given traffic class. This function uses devm_kcalloc which will zero-allocate the structure. Thus, prior to any queue being setup by ice_ena_vsi_txq, the q_ctx structure will have a q_handle of 0 and a q_teid of 0. These are potentially valid values. Modify the ice_alloc_lan_q_ctx function to initialize every member of the q_ctx array to have invalid values. Modify ice_dis_vsi_txq to ensure that it assigns q_teid to an invalid value when it assigns q_handle to the invalid value as well. This will allow other code to check whether the queue context is currently valid before operating on it.

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.
