Linux kernel source tree
e845520707
Add gcmaes_crypt_by_sg routine, that will do scatter/gather by sg. Either src or dst may contain multiple buffers, so iterate over both at the same time if they are different. If the input is the same as the output, iterate only over one. Currently both the AAD and TAG must be linear, so copy them out with scatterlist_map_and_copy. If first buffer contains the entire AAD, we can optimize and not copy. Since the AAD can be any size, if copied it must be on the heap. TAG can be on the stack since it is always < 16 bytes. Only the SSE routines are updated so far, so leave the previous gcmaes_en/decrypt routines, and branch to the sg ones if the keysize is inappropriate for avx, or we are SSE only.

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.
