Tariq Toukan says: ==================== TLS device offload for Bond This series opens TX and RX TLS device offload for bond interfaces. This allows bond interfaces to benefit from capable lower devices. We add a new ndo_sk_get_lower_dev() to be used to get the lower dev that corresponds to a given socket. The TLS module uses it to interact directly with the lowest device in chain, and invoke the control operations in tlsdev_ops. This means that the bond interface doesn't have his own struct tlsdev_ops instance and derived logic/callbacks. To keep simple track of the HW and SW TLS contexts, we bind each socket to a specific lower device for the socket's whole lifetime. This is logically valid (and similar to the SW kTLS behavior) in the following bond configuration, so we restrict the offload support to it: ((mode == balance-xor) or (mode == 802.3ad)) and xmit_hash_policy == layer3+4. In this design, TLS TX/RX offload feature flags of the bond device are independent from the lower devices. They reflect the current features state, but are not directly controllable. This is because the bond driver is bypassed by the call to ndo_sk_get_lower_dev(), without him knowing who the caller is. The bond TLS feature flags are set/cleared only according to the configuration of the mode and xmit_hash_policy. Bypass is true only for the control flow. Packets in fast path still go through the bond logic. The design here differs from the xfrm/ipsec offload, where the bond driver has his own copy of struct xfrmdev_ops and callbacks. ==================== Link: https://lore.kernel.org/r/20210117145949.8632-1-tariqt@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

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.
