In order to stop useless driver version bumps and unify output presented by ethtool -i, let's set default version string. As Linus said in [1]: "Things are supposed to be backwards and forwards compatible, because we don't accept breakage in user space anyway. So versioning is pointless, and only causes problems." They cause problems when users start to see version changes and expect specific set of features which will be different for stable@, vanilla and distribution kernels. Distribution kernels are based on some kernel version with extra patches on top, for example, in RedHat world this "extra" is a lot and for them your driver version say nothing. Users who run vanilla kernels won't use driver version information too, because running such kernels requires knowledge and understanding. Another set of problems are related to difference in versioning scheme and such doesn't allow to write meaningful automation which will work sanely on all ethtool capable devices. Before this change: [leonro@erver ~]$ ethtool -i eth0 driver: virtio_net version: 1.0.0 After this change and once ->version assignment will be deleted from virtio_net: [leonro@server ~]$ ethtool -i eth0 driver: virtio_net version: 5.5.0-rc6+ Link: https://lore.kernel.org/ksummit-discuss/CA+55aFx9A=5cc0QZ7CySC4F2K7eYaEfzkdYEc9JaNgCcV25=rg@mail.gmail.com/ Link: https://lore.kernel.org/linux-rdma/20200122152627.14903-1-michal.kalderon@marvell.com/T/#md460ff8f976c532a89d6860411c3c50bb811038b Link: https://lore.kernel.org/linux-rdma/20200127060835.GA570@unicorn.suse.czSigned-off-by:

Alex Maftei says: ==================== sfc: refactor mcdi filtering code Splitting final bits of the driver code into different files, which will later be used in another driver for a new product. This is a continuation to my previous patch series. (three of them) Refactoring will be concluded with this series, for now. As instructed, split the renaming and moving into different patches. Removed stray spaces before tabs... twice. Minor refactoring was done with the renaming, as explained in the first patch. ==================== Signed-off-by: -

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:

The dev_port is meant to distinguish the network ports belonging to the same PCI function. Our devices only have one network port associated with each PCI function and so we should not set it for correctness. 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: -

The notification message has the same format as reply to DEBUG_GET request. As with other ethtool notifications, netlink requests only trigger the notification if the mask is actually changed while ioctl request trigger it whenever the request results in calling the ethtool_ops handler.

Yoshiki Komachi says: ==================== When I tried a test based on the selftest program for BPF flow dissector (test_flow_dissector.sh), I observed unexpected result as below: $ tc filter add dev lo parent ffff: protocol ip pref 1337 flower ip_proto \ udp src_port 8-10 action drop $ tools/testing/selftests/bpf/test_flow_dissector -i 4 -f 9 -F inner.dest4: 127.0.0.1 inner.source4: 127.0.0.3 pkts: tx=10 rx=10 The last rx means the number of received packets. I expected rx=0 in this test (i.e., all received packets should have been dropped), but it resulted in acceptance. Although the previous commit 8ffb055b ("cls_flower: Fix the behavior using port ranges with hw-offload") added new flag and field toward filtering based on port ranges with hw-offload, it missed applying for BPF flow dissector then. As a result, BPF flow dissector currently stores data extracted from packets in incorrect field used for exact match whenever packets are classified by filters based on port ranges. Thus, they never match rules in such cases because flow dissector gives rise to generating incorrect flow keys. This series fixes the issue by replacing incorrect flag and field with new ones in BPF flow dissector, and adds a test for filtering based on specified port ranges to the existing selftest program. Changes in v2: - set key_ports to NULL at the top of __skb_flow_bpf_to_target() ==================== Signed-off-by:

Now that we depend on rcu_call() and synchronize_rcu() to also wait for preempt_disabled region to complete the rcu read critical section in __dev_map_flush() is no longer required. Except in a few special cases in drivers that need it for other reasons. These originally ensured the map reference was safe while a map was also being free'd. And additionally that bpf program updates via ndo_bpf did not happen while flush updates were in flight. But flush by new rules can only be called from preempt-disabled NAPI context. The synchronize_rcu from the map free path and the rcu_call from the delete path will ensure the reference there is safe. So lets remove the rcu_read_lock and rcu_read_unlock pair to avoid any confusion around how this is being protected. If the rcu_read_lock was required it would mean errors in the above logic and the original patch would also be wrong. Now that we have done above we put the rcu_read_lock in the driver code where it is needed in a driver dependent way. I think this helps readability of the code so we know where and why we are taking read locks. Most drivers will not need rcu_read_locks here and further XDP drivers already have rcu_read_locks in their code paths for reading xdp programs on RX side so this makes it symmetric where we don't have half of rcu critical sections define in driver and the other half in devmap.

virtio_net currently relies on rcu critical section to access the xdp program in its xdp_xmit handler. However, the pointer to the xdp program is only used to do a NULL pointer comparison to determine if xdp is enabled or not. Use rcu_access_pointer() instead of rcu_dereference() to reflect this. Then later when we drop rcu_read critical section virtio_net will not need in special handling. Signed-off-by:
