Latest kernels get the phys_port_name via devlink, if ndo_get_phys_port_name is not defined. To provide the phys_port_name correctly, register devlink before registering netdev. Also call devlink_port_type_eth_set() after registering netdev as devlink port updates the netdev structure and notifies user. Cc: Jiri Pirko <jiri@mellanox.com> Signed-off-by:

If the 2nd parameter fw_dflt is not set, we are calling bnxt_probe_phy() after the firmware has reset. There is no need to query the current PHY settings from firmware as these settings may be different from the ethtool settings that the driver will re-establish later. So return earlier in bnxt_probe_phy() to save one firmware call. Signed-off-by:

In bnxt_update_phy_setting(), ethtool_get_link_ksettings() and bnxt_disable_an_for_lpbk(), we inconsistently use netif_carrier_ok() to determine link. Instead, we should use bp->link_info.link_up which has the true link state. The netif_carrier state may be off during self-test and while the device is being reset and may not always reflect the true link state. By always using bp->link_info.link_up, the code is now more consistent and more correct. Some unnecessary link toggles are now prevented with this patch. Signed-off-by:

Michal Kubecek says: ==================== ethtool netlink interface, part 2 This shorter series adds support for getting and setting of wake-on-lan settings and message mask (originally message level). Together with the code already in net-next, this will allow full implementation of "ethtool <dev>" and "ethtool -s <dev> ...". Older versions of the ethtool netlink series allowed getting WoL settings by unprivileged users and only filtered out the password but this was a source of controversy so for now, ETHTOOL_MSG_WOL_GET request always requires CAP_NET_ADMIN as ETHTOOL_GWOL ioctl request does. ==================== Signed-off-by:

DSA sets up a switch tree little by little. Every switch of the N members of the tree calls dsa_register_switch, and (N - 1) will just touch the dst->ports list with their ports and quickly exit. Only the last switch that calls dsa_register_switch will find all DSA links complete in dsa_tree_setup_routing_table, and not return zero as a result but instead go ahead and set up the entire DSA switch tree (practically on behalf of the other switches too). The trouble is that the (N - 1) switches don't clean up after themselves after they get an error such as EPROBE_DEFER. Their footprint left in dst->ports by dsa_switch_touch_ports is still there. And switch N, the one responsible with actually setting up the tree, is going to work with those stale dp, dp->ds and dp->ds->dev pointers. In particular ds and ds->dev might get freed by the device driver. Be there a 2-switch tree and the following calling order: - Switch 1 calls dsa_register_switch - Calls dsa_switch_touch_ports, populates dst->ports - Calls dsa_port_parse_cpu, gets -EPROBE_DEFER, exits. - Switch 2 calls dsa_register_switch - Calls dsa_switch_touch_ports, populates dst->ports - Probe doesn't get deferred, so it goes ahead. - Calls dsa_tree_setup_routing_table, which returns "complete == true" due to Switch 1 having called dsa_switch_touch_ports before. - Because the DSA links are complete, it calls dsa_tree_setup_switches now. - dsa_tree_setup_switches iterates through dst->ports, initializing the Switch 1 ds structure (invalid) and the Switch 2 ds structure (valid). - Undefined behavior (use after free, sometimes NULL pointers, etc). Real example below (debugging prints added by me, as well as guards against NULL pointers): [ 5.477947] dsa_tree_setup_switches: Setting up port 0 of switch ffffff803df0b980 (dev ffffff803f775c00) [ 6.313002] dsa_tree_setup_switches: Setting up port 1 of switch ffffff803df0b980 (dev ffffff803f775c00) [ 6.319932] dsa_tree_setup_switches: Setting up port 2 of switch ffffff803df0b980 (dev ffffff803f775c00) [ 6.329693] dsa_tree_setup_switches: Setting up port 3 of switch ffffff803df0b980 (dev ffffff803f775c00) [ 6.339458] dsa_tree_setup_switches: Setting up port 4 of switch ffffff803df0b980 (dev ffffff803f775c00) [ 6.349226] dsa_tree_setup_switches: Setting up port 5 of switch ffffff803df0b980 (dev ffffff803f775c00) [ 6.358991] dsa_tree_setup_switches: Setting up port 6 of switch ffffff803df0b980 (dev ffffff803f775c00) [ 6.368758] dsa_tree_setup_switches: Setting up port 7 of switch ffffff803df0b980 (dev ffffff803f775c00) [ 6.378524] dsa_tree_setup_switches: Setting up port 8 of switch ffffff803df0b980 (dev ffffff803f775c00) [ 6.388291] dsa_tree_setup_switches: Setting up port 9 of switch ffffff803df0b980 (dev ffffff803f775c00) [ 6.398057] dsa_tree_setup_switches: Setting up port 10 of switch ffffff803df0b980 (dev ffffff803f775c00) [ 6.407912] dsa_tree_setup_switches: Setting up port 0 of switch ffffff803da02f80 (dev 0000000000000000) [ 6.417682] dsa_tree_setup_switches: Setting up port 1 of switch ffffff803da02f80 (dev 0000000000000000) [ 6.427446] dsa_tree_setup_switches: Setting up port 2 of switch ffffff803da02f80 (dev 0000000000000000) [ 6.437212] dsa_tree_setup_switches: Setting up port 3 of switch ffffff803da02f80 (dev 0000000000000000) [ 6.446979] dsa_tree_setup_switches: Setting up port 4 of switch ffffff803da02f80 (dev 0000000000000000) [ 6.456744] dsa_tree_setup_switches: Setting up port 5 of switch ffffff803da02f80 (dev 0000000000000000) [ 6.466512] dsa_tree_setup_switches: Setting up port 6 of switch ffffff803da02f80 (dev 0000000000000000) [ 6.476277] dsa_tree_setup_switches: Setting up port 7 of switch ffffff803da02f80 (dev 0000000000000000) [ 6.486043] dsa_tree_setup_switches: Setting up port 8 of switch ffffff803da02f80 (dev 0000000000000000) [ 6.495810] dsa_tree_setup_switches: Setting up port 9 of switch ffffff803da02f80 (dev 0000000000000000) [ 6.505577] dsa_tree_setup_switches: Setting up port 10 of switch ffffff803da02f80 (dev 0000000000000000) [ 6.515433] dsa_tree_setup_switches: Setting up port 0 of switch ffffff803db15b80 (dev ffffff803d8e4800) [ 7.354120] dsa_tree_setup_switches: Setting up port 1 of switch ffffff803db15b80 (dev ffffff803d8e4800) [ 7.361045] dsa_tree_setup_switches: Setting up port 2 of switch ffffff803db15b80 (dev ffffff803d8e4800) [ 7.370805] dsa_tree_setup_switches: Setting up port 3 of switch ffffff803db15b80 (dev ffffff803d8e4800) [ 7.380571] dsa_tree_setup_switches: Setting up port 4 of switch ffffff803db15b80 (dev ffffff803d8e4800) [ 7.390337] dsa_tree_setup_switches: Setting up port 5 of switch ffffff803db15b80 (dev ffffff803d8e4800) [ 7.400104] dsa_tree_setup_switches: Setting up port 6 of switch ffffff803db15b80 (dev ffffff803d8e4800) [ 7.409872] dsa_tree_setup_switches: Setting up port 7 of switch ffffff803db15b80 (dev ffffff803d8e4800) [ 7.419637] dsa_tree_setup_switches: Setting up port 8 of switch ffffff803db15b80 (dev ffffff803d8e4800) [ 7.429403] dsa_tree_setup_switches: Setting up port 9 of switch ffffff803db15b80 (dev ffffff803d8e4800) [ 7.439169] dsa_tree_setup_switches: Setting up port 10 of switch ffffff803db15b80 (dev ffffff803d8e4800) The solution is to recognize that the functions that call dsa_switch_touch_ports (dsa_switch_parse_of, dsa_switch_parse) have side effects, and therefore one should clean up their side effects on error path. The cleanup of dst->ports was taken from dsa_switch_remove and moved into a dedicated dsa_switch_release_ports function, which should really be per-switch (free only the members of dst->ports that are also members of ds, instead of all switch ports).

Steffen Klassert says: ==================== Support fraglist GRO/GSO This patchset adds support to do GRO/GSO by chaining packets of the same flow at the SKB frag_list pointer. This avoids the overhead to merge payloads into one big packet, and on the other end, if GSO is needed it avoids the overhead of splitting the big packet back to the native form. Patch 1 adds netdev feature flags to enable fraglist GRO, this implements one of the configuration options discussed at netconf 2019. Patch 2 adds a netdev software feature set that defaults to off and assigns the new fraglist GRO feature flag to it. Patch 3 adds the core infrastructure to do fraglist GRO/GSO. Patch 4 enables UDP to use fraglist GRO/GSO if configured. I have only meaningful forwarding performance measurements. I did some tests for the local receive path with netperf and iperf, but in this case the sender that generates the packets is the bottleneck. So the benchmarks are not that meaningful for the receive path. Paolo Abeni did some benchmarks of the local receive path for the RFC v2 version of this pachset, results can be found here: https://www.spinics.net/lists/netdev/msg551158.html I used my IPsec forwarding test setup for the performance measurements: ------------ ------------ -->| router 1 |-------->| router 2 |-- | ------------ ------------ | | | | -------------------- | --------|Spirent Testcenter|<---------- -------------------- net-next (September 7th 2019): Single stream UDP frame size 1460 Bytes: 1.161.000 fps (13.5 Gbps). ---------------------------------------------------------------------- net-next (September 7th 2019) + standard UDP GRO/GSO (not implemented in this patchset): Single stream UDP frame size 1460 Bytes: 1.801.000 fps (21 Gbps). ---------------------------------------------------------------------- net-next (September 7th 2019) + fraglist UDP GRO/GSO: Single stream UDP frame size 1460 Bytes: 2.860.000 fps (33.4 Gbps). ======================================================================= net-next (January 23th 2020): Single stream UDP frame size 1460 Bytes: 919.000 fps (10.73 Gbps). ---------------------------------------------------------------------- net-next (January 23th 2020) + fraglist UDP GRO/GSO: Single stream UDP frame size 1460 Bytes: 2.430.000 fps (28.38 Gbps). ----------------------------------------------------------------------- Changes from RFC v1: - Add IPv6 support. - Split patchset to enable UDP GRO by default before adding fraglist GRO support. - Mark fraglist GRO packets as CHECKSUM_NONE. - Take a refcount on the first segment skb when doing fraglist segmentation. With this we can use the same error handling path as with standard segmentation. Changes from RFC v2: - Add a netdev feature flag to configure listifyed GRO. - Fix UDP GRO enabling for IPv6. - Fix a rcu_read_lock() imbalance. - Fix error path in skb_segment_list(). Changes from RFC v3: - Rename NETIF_F_GRO_LIST to NETIF_F_GRO_FRAGLIST and add NETIF_F_GSO_FRAGLIST. - Move introduction of SKB_GSO_FRAGLIST to patch 2. - Use udpv6_encap_needed_key instead of udp_encap_needed_key in IPv6. - Move some missplaced code from patch 5 to patch 1 where it belongs to. Changes from RFC v4: - Drop the 'UDP: enable GRO by default' patch for now. Standard UDP GRO is not changed with this patchset. - Rebase to net-next current. Changes fom v1 (December 18th): - Do a full __copy_skb_header instead of tryng to find the really needed subset header fields. Thisa can be done later. - Mark all fraglist GRO packets with CHECKSUM_UNNECESSARY. - Rebase to net-next current.

This patch extends UDP GRO to support fraglist GRO/GSO by using the previously introduced infrastructure. If the feature is enabled, all UDP packets are going to fraglist GRO (local input and forward). After validating the csum, we mark ip_summed as CHECKSUM_UNNECESSARY for fraglist GRO packets to make sure that the csum is not touched. Signed-off-by:

Recently XDP Support was added to the mvneta driver for software buffer management only. It is still possible to attach an XDP program if hardware buffer management is used. It is not doing anything at that point. The patch disallows attaching XDP programs to mvneta if hardware buffer management is used. I am sorry about that. It is my first submission and I am having some troubles with the format of my emails. v4 -> v5: - Remove extra tabs v3 -> v4: - Please ignore v3 I accidentally submitted my other patch with git-send-mail and v4 is correct v2 -> v3: - My mailserver corrupted the patch resubmission with git-send-email v1 -> v2: - Fixing the patches indentation Signed-off-by:
