commitdcf7b48212upstream. The original assembly imported from OpenSSL has two copy-paste errors in handling CTR mode. When dealing with a 2 or 3 block tail, the code branches to the CBC decryption exit path, rather than to the CTR exit path. This leads to corruption of the IV, which leads to subsequent blocks being corrupted. This can be detected with libkcapi test suite, which is available at https://github.com/smuellerDD/libkcapi Reported-by: Ondrej Mosnáček <omosnacek@gmail.com> Fixes:5c380d623e("crypto: vmx - Add support for VMS instructions by ASM") Cc: stable@vger.kernel.org Signed-off-by: Daniel Axtens <dja@axtens.net> Tested-by: Michael Ellerman <mpe@ellerman.id.au> Tested-by: Ondrej Mosnacek <omosnacek@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
