When ctr-aes-qce is used for gcm-mode, an extra sg entry for the authentication tag is present, causing trouble when the qce driver prepares the dst-results sg table for dma. It computes the number of entries needed with sg_nents_for_len, leaving out the tag entry. Then it creates a sg table with that number plus one, used to store a result buffer. When copying the sg table, there's no limit to the number of entries copied, so the extra slot is filled with the authentication tag sg. When the driver tries to add the result sg, the list is full, and it returns EINVAL. By limiting the number of sg entries copied to the dest table, the slot for the result buffer is guaranteed to be unused.

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.
