* net: ethtool: add missing NETIF_F_GSO_FRAGLIST feature stringAlexander Lobakin2020-06-181-0/+1
| | | | | | | | | | | | | Commit 3b33583265ed ("net: Add fraglist GRO/GSO feature flags") missed an entry for NETIF_F_GSO_FRAGLIST in netdev_features_strings array. As a result, fraglist GSO feature is not shown in 'ethtool -k' output and can't be toggled on/off. The fix is trivial.

We've added 50 non-merge commits during the last 8 day(s) which contain a total of 109 files changed, 2776 insertions(+), 2887 deletions(-). The main changes are: 1) Add a new AF_XDP buffer allocation API to the core in order to help lowering the bar for drivers adopting AF_XDP support. i40e, ice, ixgbe as well as mlx5 have been moved over to the new API and also gained a small improvement in performance, from Björn Töpel and Magnus Karlsson. 2) Add getpeername()/getsockname() attach types for BPF sock_addr programs in order to allow for e.g. reverse translation of load-balancer backend to service address/port tuple from a connected peer, from Daniel Borkmann. 3) Improve the BPF verifier is_branch_taken() logic to evaluate pointers being non-NULL, e.g. if after an initial test another non-NULL test on that pointer follows in a given path, then it can be pruned right away, from John Fastabend. 4) Larger rework of BPF sockmap selftests to make output easier to understand and to reduce overall runtime as well as adding new BPF kTLS selftests that run in combination with sockmap, also from John Fastabend. 5) Batch of misc updates to BPF selftests including fixing up test_align to match verifier output again and moving it under test_progs, allowing bpf_iter selftest to compile on machines with older vmlinux.h, and updating config options for lirc and v6 segment routing helpers, from Stanislav Fomichev, Andrii Nakryiko and Alan Maguire. 6) Conversion of BPF tracing samples outdated internal BPF loader to use libbpf API instead, from Daniel T. Lee. 7) Follow-up to BPF kernel test infrastructure in order to fix a flake in the XDP selftests, from Jesper Dangaard Brouer. 8) Minor improvements to libbpf's internal hashmap implementation, from Ian Rogers. ==================== Signed-off-by: David S.

Due to lack of auto-negotiation support, we needed to be able to configure the MASTER-SLAVE role of the port manually or from an application in user space. The same UAPI can be used for 1000BASE-T or MultiGBASE-T devices to force MASTER or SLAVE role. See IEEE 802.3-2018: 22.2.4.3.7 MASTER-SLAVE control register (Register 9) 22.2.4.3.8 MASTER-SLAVE status register (Register 10) 40.5.2 MASTER-SLAVE configuration resolution 45.2.1.185.1 MASTER-SLAVE config value (1.2100.14) 45.2.7.10 MultiGBASE-T AN control 1 register (Register 7.32) The MASTER-SLAVE role affects the clock configuration: ------------------------------------------------------------------------------- When the PHY is configured as MASTER, the PMA Transmit function shall source TX_TCLK from a local clock source.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Andrew noticed that some handlers for *_SET commands leak a netdev reference if required ethtool_ops callbacks do not exist. A simple reproducer would be e.g. ip link add veth1 type veth peer name veth2 ethtool -s veth1 wol g ip link del veth1 Make sure dev_put() is called when ethtool_ops check fails. v2: add Fixes tags Fixes: a53f3d41e4d3 ("ethtool: set link settings with LINKINFO_SET request") Fixes: bfbcfe2032e7 ("ethtool: set link modes related data with LINKMODES_SET request") Fixes: e54d04e3afea ("ethtool: set message mask with DEBUG_SET request") Fixes: 8d425b19b305 ("ethtool: set wake-on-lan settings with WOL_SET request") Reported-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Reviewed-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | As pointed out by Jakub Kicinski, we ethtool netlink code should respond with an error if request head has flags set which are not recognized by kernel, either as a mistake or because it expects functionality introduced in later kernel versions. To avoid unnecessary roundtrips, use extack cookie to provide the information about supported request flags. Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, ethtool feature mask for checksum command is ORed with NETIF_F_FCOE_CRC_BIT, which is bit's position number, instead of the actual feature bit - NETIF_F_FCOE_CRC. The invalid bitmask here might affect unrelated features when toggling TX checksumming. For example, TX checksumming is always mistakenly reported as enabled on the netdevs tested (mlx5, virtio_net).
