4.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Robert Baronescu <robert.baronescu@xxxxxxx> [ Upstream commit 7aacbfcb331ceff3ac43096d563a1f93ed46e35e ] Fix the way the length of the buffers used for encryption / decryption are computed. For e.g. in case of encryption, input buffer does not contain an authentication tag.
