2023-06-08crypto: af_alg: Pin pages rather than ref'ing if appropriateDavid Howells
Convert AF_ALG to use iov_iter_extract_pages() instead of iov_iter_get_pages(). This will pin pages or leave them unaltered rather than getting a ref on them as appropriate to the iterator. The pages need to be pinned for DIO-read rather than having refs taken on them to prevent VM copy-on-write from malfunctioning during a concurrent fork() (the result of the I/O would otherwise end up only visible to the child process and not the parent).

2023-06-08bnxt_en: Implement .set_port / .unset_port UDP tunnel callbacksSomnath Kotur
As per the new udp tunnel framework, drivers which need to know the details of a port entry (i.e. port type) when it gets deleted should use the .set_port / .unset_port callbacks. Implementing the current .udp_tunnel_sync callback would mean that the deleted tunnel port entry would be all zeros. This used to work on older firmware because it would not check the input when deleting a tunnel port. With newer firmware, the delete will now fail and subsequent tunnel port allocation will fail as a result.

Fix it by not registering for this event with the firmware if !bp->ptp_cfg. Also, check that bp->ptp_cfg is valid before proceeding when we receive the event.

2023-06-08bnxt_en: Query default VLAN before VNIC setup on a VFSomnath Kotur
We need to call bnxt_hwrm_func_qcfg() on a VF to query the default VLAN that may be setup by the PF. If a default VLAN is enabled, the VF cannot support VLAN acceleration on the receive side and the VNIC must be setup to strip out the default VLAN tag. If a default VLAN is not enabled, the VF can support VLAN acceleration on the receive side. The VNIC should be set up to strip or not strip the VLAN based on the RX VLAN acceleration setting. Without this call to determine the default VLAN before calling bnxt_setup_vnic(), the VNIC may not be set up correctly. For example, bnxt_setup_vnic() may set up to strip the VLAN tag based on stale default VLAN information. If RX VLAN acceleration is not enabled, the VLAN tag will be incorrectly stripped and the RX data path will not work correctly.

Commit bffaa916588e ("net/mlx5: E-Switch, Add control for inline mode") added inline mode checking to esw_offloads_start() with a warning printed out in case there is a problem. Tne inline mode checking was done even after mlx5_eswitch_enable_locked() call failed, which is pointless. Later on, commit 8c98ee77d911 ("net/mlx5e: E-Switch, Add extack messages to devlink callbacks") converted the error/warning prints to extack setting, which caused that the inline mode check error to overwrite possible previous extack message when mlx5_eswitch_enable_locked() failed.

2023-06-07net/mlx5: LAG, generalize handling of shared FDBShay Drory
Shared FDB handling is using the assumption that shared FDB can only be created from two devices. In order to support shared FDB of more than two devices, iterate over all LAG ports instead of hard coding only the first two LAG ports whenever handling shared FDB.

2023-06-07net/mlx5: LAG, check if all eswitches are paired for shared FDBShay Drory
Shared FDB LAG can only work if all eswitches are paired. Also, whenever two eswitches are paired, devcom is marked as ready. Therefore, in case of device with two eswitches, checking devcom was sufficient. However, this is not correct for device with more than two eswitches, which will be introduced in downstream patch. Hence, check all eswitches are paired explicitly. Signed-off-by: Shay Drory <shayd@nvidia.com> Reviewed-by: Mark Bloch <mbloch@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>

Maxime Chevallier says: ==================== Followup fixes for the dwmac and altera lynx conversion Here's yet another version of the cleanup series for the TSE PCS replacement by PCS Lynx. It includes Kconfig fixups, some missing initialisations and a slight rework suggested by Russell for the dwmac cleanup sequence, along with more explicit zeroing of local structures as per MAciej's review. ==================== Link: https://lore.kernel.org/r/20230607135941.407054-1-maxime.chevallier@bootlin.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
