Implement the getsockopt SOL_TLS TLS_RX which is currently missing. The primary usecase is to use it in conjunction with TCP_REPAIR to checkpoint/restore the TLS record layer state. TLS connection state usually exists on the user space library. So basically we can easily extract it from there, but when the TLS connections are delegated to the kTLS, it is not the case. We need to have a way to extract the TLS state from the kernel for both of TX and RX side. The new TLS_RX getsockopt copies the crypto_info to user in the same way as TLS_TX does. We have described use cases in our research work in Netdev 0x14 Transport Workshop [1]. Also, there is an TLS implementation called tlse [2] which supports TLS connection migration. They have support of kTLS and their code shows that they are expecting the future support of this option.

keep_flows was introduced by [1], which used as flag to delete flows or not. When rehashing or expanding the table instance, we will not flush the flows. Now don't use it anymore, remove it.

Decrease table->count and ufid_count unconditionally, because we only don't use count or ufid_count to count when flushing the flows. To simplify the codes, we remove the "count" argument of table_instance_flow_free. To avoid a bug when deleting flows in the future, add WARN_ON in flush flows function.

Ioana Ciornei says: ==================== net: phy: add Lynx PCS MDIO module Add support for the Lynx PCS as a separate module in drivers/net/phy/. The advantage of this structure is that multiple ethernet or switch drivers used on NXP hardware (ENETC, Seville, Felix DSA switch etc) can share the same implementation of PCS configuration and runtime management. The module implements phylink_pcs_ops and exports a phylink_pcs (incorporated into a lynx_pcs) which can be directly passed to phylink through phylink_pcs_set. The first 3 patches add some missing pieces in phylink and the locked mdiobus write accessor. Next, the Lynx PCS MDIO module is added as a standalone module. The majority of the code is extracted from the Felix DSA driver. The last patch makes the necessary changes in the Felix and Seville drivers in order to use the new common PCS implementation. At the moment, USXGMII (only with in-band AN), SGMII, QSGMII (with and without in-band AN) and 2500Base-X (only w/o in-band AN) are supported by the Lynx PCS MDIO module since these were also supported by Felix and no functional change is intended at this time. Changes in v2: * got rid of the mdio_lynx_pcs structure and directly exported the functions without the need of an indirection * made the necessary adjustments for this in the Felix DSA driver * solved the broken allmodconfig build test by making the module tristate instead of bool * fixed a memory leakage in the Felix driver (the pcs structure was allocated twice) Changes in v3: * added support for PHYLINK PCS ops in DSA (patch 5/9) * cleanup in Felix PHYLINK operations and migrate to phylink_mac_link_up() being the callback of choice for applying MAC configuration (patches 6-8) Changes in v4: * use the newly introduced phylink PCS mechanism * install the phylink_pcs in the phylink_mac_config DSA ops * remove the direct implementations of the PCS ops * do no use the SGMII_ prefix when referring to the IF_MORE register * add a phylink helper to decode the USXGMII code word * remove cleanup patches for Felix (these have been already accepted) * Seville (recently introduced) now has PCS support through the same Lynx PCS module Changes in v5: - move the pcs-lynx driver to drivers/net/pcs - reword the commit message a bit in 4/5 - add error checking and error propagation in 4/5 - s/IF_MODE_DUPLEX/IF_MODE_HALF_DUPLEX in 4/5 ==================== Signed-off-by: -

Use the helper functions introduced by the newly added Lynx PCS MDIO module in the Felix VSC9959 and Seville VSC9953. Instead of representing the PCS as a phy_device, a mdio_device structure will be passed to the Lynx module which is now actually implementing all the PCS configuration and status reporting. All code previously used for PCS monitoring and runtime configuration is removed and replaced will calls to the Lynx PCS operations. Tested on the following SERDES protocols of LS1028A: 0x7777 (2500Base-X), 0x85bb (QSGMII), 0x9999 (SGMII) and 0x13bb (USXGMII). Signed-off-by:

Add a Lynx PCS module which exposes the necessary operations to drive the PCS using phylink. The majority of the code is extracted from the Felix DSA driver, which will be also modified in a later patch, and exposed as a separate module for code reusability purposes. As such, this aims at feature and bug parity with the existing Felix DSA driver, and thus USXGMII, SGMII, QSGMII and 2500Base-X (only w/o in-band AN) are supported by the Lynx PCS module since these were also supported by Felix. The module can only be enabled by the drivers in need and not user selectable. Signed-off-by:

Edward Cree says: ==================== sfc: clean up some W=1 build warnings A collection of minor fixes to issues flagged up by W=1. After this series, the only remaining warnings in the sfc driver are some 'member missing in kerneldoc' warnings from ptp.c. Tested by building on x86_64 and running 'ethtool -p' on an EF10 NIC; there was no error, but I couldn't observe the actual LED as I'm working remotely. [ Incidentally, ethtool_phys_id()'s behaviour on an error return looks strange — if I'm reading it right, it will break out of the inner loop but not the outer one, and eventually return the rc from the last run of the inner loop. Is this intended? ] ==================== Reviewed-by:

Edward Cree authored
W=1 warnings indicated that 'rc' was unused in efx_mcdi_set_id_led(); change the function to return int instead of void and plumb the rc through the caller efx_ethtool_phys_id(). Since (post-Falcon) all sfc NICs use MCDI for this, there's no point in indirecting through a nic_type method, so remove that and just call efx_mcdi_set_id_led() directly. Signed-off-by:

If we intend to use PCS operations, mac_pcs_get_state() will not be implemented, so will be NULL. If we also intend to register the PCS operations in mac_prepare() or mac_config(), then this leads to an attempt to call NULL function pointer during phylink_start(). Avoid this, but we must report the link is down. Signed-off-by:

In the policy export for binary attributes I erroneously used a != NLA_VALIDATE_NONE comparison instead of checking for the two possible values, which meant that if a validation function pointer ended up aliasing the min/max as negatives, we'd hit a warning in nla_get_range_unsigned(). Fix this to correctly check for only the two types that should be handled here, i.e. range with or without warn-too-long.
