Jakub Kicinski says: ==================== netlink: support reporting missing attributes This series adds support for reporting missing attributes in a structured way. We communicate the type of the missing attribute and if it was missing inside a nest the offset of that nest. Example of (YAML-based) user space reporting ethtool header missing: Kernel error: missing attribute: .header I was tempted to integrate the check with the policy but it seems tricky without doing a full scan, and there may be a ton of attrs in the policy. So leaving that for later. ==================== Link: https://lore.kernel.org/r/20220826030935.2165661-1-kuba@kernel.orgSigned-off-by:

The actual presence check for the header is in ethnl_parse_header_dev_get() but it's a few layers in, and already has a ton of arguments so let's just pick the low hanging fruit and check for missing header in the default request handler. Reviewed-by:

Being able to check attribute presence and set extack if not on one line is handy, add helpers. Reviewed-by:
-
Jakub Kicinski authored
There is currently no way to report via extack in a structured way that an attribute is missing. This leads to families resorting to string messages. Add a pair of attributes - @offset and @type for machine-readable way of reporting missing attributes. The @offset points to the nest which should have contained the attribute, @type is the expected nla_type. The offset will be skipped if the attribute is missing at the message level rather than inside a nest. User space should be able to figure out which attribute enum (AKA attribute space AKA attribute set) the nest pointed to by @offset is using. Reviewed-by:

The ext_ack writing code looks very "organically grown". Move the calculation of the size and writing out to helpers. This is more idiomatic and gives us the ability to return early avoiding the long (and randomly ordered) "if" conditions. Reviewed-by:

Simon Horman says: ==================== nfp: port speed and eeprom get/set updates this short series is the initial updates for the NFP driver for the v6.1 Kernel. It covers two enhancements: 1. Patches 1/3 and 2/3: - Support cases where application firmware does not know port speeds a priori by relaying this information from the management firmware to the application firmware. This allows the existing mechanism, whereby the driver reports port speeds to user-space as provided by the application firmware, to work in this case. 2. Patch 2/3: - Add support for eeprom get and set command ==================== Link: https://lore.kernel.org/r/20220825141223.22346-1-simon.horman@corigine.comSigned-off-by: -

Yinjun Zhang authored
In future releases the NIC application firmware may be indifferent to port speeds - not built for specific port speeds - and consequently it will not be able to report VF port speeds to the driver without first learning them. With this change, the driver will pass the speed of physical ports from management firmware to application firmware, and the latter will copy the speed of port 0 to all the active VFs. So that the driver can get VF port speed as before. The port speed of a VF may be requested from userspace using: ethtool <vf-intf> Signed-off-by:

Casper Andersson says: ==================== net: sparx5: add mrouter support This series adds support for multicast router ports to SparX5. To manage mrouter ports the driver must keep track of mdb entries. When adding an mrouter port the driver has to iterate over all mdb entries and modify them accordingly. v2: - add bailout in free_mdb - re-arrange mdb struct to avoid holes - change devm_kzalloc -> kzalloc - change GFP_ATOMIC -> GFP_KERNEL - fix spelling ==================== Reviewed-by:

We had historically not checked that genlmsghdr.reserved is 0 on input which prevents us from using those precious bytes in the future. One use case would be to extend the cmd field, which is currently just 8 bits wide and 256 is not a lot of commands for some core families. To make sure that new families do the right thing by default put the onus of opting out of validation on existing families. Signed-off-by:

Andrey Zhadchenko says: ==================== openvswitch: allow specifying ifindex of new interfaces CRIU currently do not support checkpoint/restore of OVS configurations, but there was several requests for it. For example, https://github.com/lxc/lxc/issues/2909 The main problem is ifindexes of newly created interfaces. We realy need to preserve them after restore. Current openvswitch API does not allow to specify ifindex. Most of the time we can just create an interface via generic netlink requests and plug it into ovs but datapaths (generally any OVS_VPORT_TYPE_INTERNAL) can only be created via openvswitch requests which do not support selecting ifindex. This patch allows to do so. For new datapaths I decided to use dp_infindex in header as infindex because it control ifindex for other requests too. For internal vports I reused OVS_VPORT_ATTR_IFINDEX. The only concern I have is that previously dp_ifindex was not used for OVS_DP_VMD_NEW requests and some software may not set it to zero. However we have been running this patch at Virtuozzo for 2 years and have not encountered this problem. Not sure if it is worth to add new ovs_datapath_attr instead. ==================== Link: https://lore.kernel.org/r/20220825020450.664147-1-andrey.zhadchenko@virtuozzo.comSigned-off-by:

CRIU is preserving ifindexes of net devices after restoration. However, current Open vSwitch API does not allow to target ifindex, so we cannot correctly restore OVS configuration. Add new OVS_DP_ATTR_IFINDEX for OVS_DP_CMD_NEW and use it as desired ifindex. Use OVS_VPORT_ATTR_IFINDEX during OVS_VPORT_CMD_NEW to specify new netdev ifindex. Signed-off-by:

In genl_bind(), currently genl_lock and write cb_lock are taken for iteration of genl_fam_idr and processing of static values stored in struct genl_family. Take just read cb_lock for this task as it is sufficient to guard the idr and the struct against concurrent genl_register/unregister_family() calls. This will allow to run genl command processing in genl_rcv() and mnl_socket_setsockopt(.., NETLINK_ADD_MEMBERSHIP, ..) in parallel. Reported-by:

The Lenovo OneLink+ Dock contains an RTL8153 controller that behaves as a broken CDC device by default. Add the custom Lenovo PID to the r8152 driver to support it properly. Also, systems compatible with this dock provide a BIOS option to enable MAC address passthrough (as per Lenovo document "ThinkPad Docking Solutions 2017"). Add the custom PID to the MAC passthrough list too. Tested on a ThinkPad 13 1st gen with the expected results: passthrough disabled: Invalid header when reading pass-thru MAC addr passthrough enabled: Using pass-thru MAC addr XX:XX:XX:XX:XX:XX Signed-off-by:

Maksym Glubokiy says: ==================== net: prestera: matchall features This patch series extracts matchall rules management out of SPAN API implementation and adds 2 features on top of that: - support for egress traffic (mirred egress action) - proper rule priorities management between matchall and flower ==================== Signed-off-by: -
Maksym Glubokiy authored
matchall rules can be added only to chain 0 and their priorities have limitations: - new matchall ingress rule's priority must be higher (lower value) than any existing flower rule; - new matchall egress rule's priority must be lower (higher value) than any existing flower rule. The opposite works for flower rule adding: - new flower ingress rule's priority must be lower (higher value) than any existing matchall rule; - new flower egress rule's priority must be higher (lower value) than any existing matchall rule. This is a hardware limitation and thus must be properly handled in driver by reporting errors to the user when newly added rule has such a priority that cannot be installed into the hardware. To achieve this, the driver must maintain both min/max matchall priorities for every flower block when user adds/deletes a matchall rule, as well as both min/max flower priorities for chain 0 for every adding/deletion of flower rules for chain 0.
