If esp*_offload module is loaded, outbound packets take the GSO code path, being encapsulated at layer 3, but encrypted in layer 2. validate_xmit_xfrm calls esp*_xmit for that. esp*_xmit was wrongfully detecting these packets as going through hardware crypto offload, while in fact they should be encrypted in software, causing plaintext leakage to the network, and also dropping at the receiver side. Perform the encryption in esp*_xmit, if the SA doesn't have a hardware offload_handle. Also, align esp6 code to esp4 logic. Fixes: |

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.
