Add support for validating keyfields and actionfields when they are added to a VCAP rule. We need to ensure that the field is not already present and that the field is in the key- or actionset, if the client has added a key- or actionset to the rule at this point. Signed-off-by:

This tries to match the keys in a rule with the keysets supported by the VCAP instance, and generate a list of keysets. This list is then validated against the list of keysets that is currently selected for the lookups (per port) in the VCAP configuration. The Sparx5 IS2 only has one actionset, so there is no actionset matching performed for now. Signed-off-by:

This adds the following TC flower filter keys to Sparx5 for IS2: - ipv4_addr (sip and dip) - ipv6_addr (sip and dip) - control (IPv4 fragments) - portnum (tcp and udp port numbers) - basic (L3 and L4 protocol) - vlan (outer vlan tag info) - tcp (tcp flags) - ip (tos field) as well as an 128 bit keyfield interface on the VCAP API to set the IPv6 addresses. IS2 supports the classified VLAN information which amounts to the outer VLAN info in case of multiple tags. Here are some examples of the tc flower filter operations that are now supported for the IS2 VCAP: - IPv4 Addresses tc filter add dev eth12 ingress chain 8000000 prio 12 handle 12 \ protocol ip flower skip_sw dst_ip 1.0.1.1 src_ip 2.0.2.2 \ action trap action goto chain 81000000 - IPv6 Addresses tc filter add dev eth12 ingress chain 8000000 prio 13 handle 13 \ protocol ipv6 flower skip_sw dst_ip 1::1:1 src_ip 2::2:2 \ action trap action goto chain 81000000 - IPv4 fragments tc filter add dev eth12 ingress chain 8000000 prio 14 handle 14 \ protocol ip flower skip_sw dst_ip 3.0.3.3 src_ip 2.0.2.2 \ ip_flags frag/nofirstfrag action trap action goto chain 81000000 - TCP and UDP portnumbers tc filter add dev eth12 ingress chain 8000000 prio 21 handle 21 \ protocol ip flower skip_sw dst_ip 8.8.8.8 src_ip 2.0.2.2 \ ip_proto tcp dst_port 100 src_port 12000 action trap action goto chain 81000000 tc filter add dev eth12 ingress chain 8000000 prio 23 handle 23 \ protocol ipv6 flower skip_sw dst_ip 5::5:5 src_ip 2::2:2 \ ip_proto tcp dst_port 300 src_port 13000 action trap action goto chain 81000000 - Layer 3 and Layer 4 protocol info tc filter add dev eth12 ingress chain 8000000 prio 28 handle 28 \ protocol ipv4 flower skip_sw dst_ip 9.0.9.9 src_ip 2.0.2.2 \ ip_proto icmp action trap action goto chain 81000000 - VLAN tag info (outer tag) tc filter add dev eth12 ingress chain 8000000 prio 29 handle 29 \ protocol 802.1q flower skip_sw vlan_id 600 vlan_prio 6 \ vlan_ethtype ipv4 action trap action goto chain 81000000 tc filter add dev eth12 ingress chain 8000000 prio 31 handle 31 \ protocol 802.1q flower skip_sw vlan_id 600 vlan_prio 5 \ vlan_ethtype ipv6 action trap action goto chain 81000000 - TCP flags tc filter add dev eth12 ingress chain 8000000 prio 15 handle 15 \ protocol ip flower skip_sw dst_ip 4.0.4.4 src_ip 2.0.2.2 \ ip_proto tcp tcp_flags 0x2a/0x3f action trap action goto chain 81000000 - IP info (IPv4 TOS field) tc filter add dev eth12 ingress chain 8000000 prio 16 handle 16 \ protocol ip flower skip_sw ip_tos 0x35 dst_ip 5.0.5.5 \ src_ip 2.0.2.2 action trap action goto chain 81000000 Notes: - The "protocol all" selection is not supported yet. - The MAC address rule now needs to use non-ip and non "protocol all". Here is an example: tc filter add dev eth12 ingress chain 8000000 prio 10 handle 10 \ protocol 0xbeef flower skip_sw \ dst_mac 0a:0b:0c:0d:0e:0f \ src_mac 2:0:0:0:0:1 \ action trap action goto chain 81000000 - The VLAN rules use classified VLAN information, and to get the classification information into the frame metadata, the ingress port need to be added to a bridge with the VID and vlan filtering enabled, like this (using VID 600 and four ports eth12, eth13, eth14 and eth15): ip link add name br5 type bridge ip link set dev br5 up ip link set eth12 master br5 ip link set eth13 master br5 ip link set eth14 master br5 ip link set eth15 master br5 sysctl -w net.ipv6.conf.eth12.disable_ipv6=1 sysctl -w net.ipv6.conf.eth13.disable_ipv6=1 sysctl -w net.ipv6.conf.eth14.disable_ipv6=1 sysctl -w net.ipv6.conf.eth15.disable_ipv6=1 sysctl -w net.ipv6.conf.br5.disable_ipv6=1 ip link set dev br5 type bridge vlan_filtering 1 bridge vlan add dev eth12 vid 600 bridge vlan add dev eth13 vid 600 bridge vlan add dev eth14 vid 600 bridge vlan add dev eth15 vid 600 bridge vlan add dev br5 vid 600 self Signed-off-by:Casper Andersson <casper.casan@gmail.com> Signed-off-by:

This changes the port keyset configuration for Sparx5 IS2 so that - IPv4 generates a IP4_TCP_UDP keyset for IPv4 TCP/UDP frames and a IP4_OTHER keyset for other IPv4 frames (both UC and MC) - IPv6 generates a IP_7TUPLE keyset (both UC and MC) ARP and non-IP traffic continues to generate the MAC_ETYPE keyset Signed-off-by:

HINIC is marked orphan for 14 months from the commit "5cfe5109", but there are lots of HINIC in use. I have a SP582 NIC (hi1822 inside which is a kind of HINIC SOC), and implement based on hinic driver, and if there are some patches for HINIC, I can test and do some code review. I'm active in linux contribution, if possible, I want to take the hinic maintainership. Add my email here to receive patches. Signed-off-by:

When a devlink port is unregistered, its type is expected to be unset or otherwise a WARNING is generated [1]. This was supposed to be handled by cited commit by clearing the type upon 'NETDEV_PRE_UNINIT'. The assumption was that no other events can be generated for the netdev after this event, but this proved to be wrong. After the event is generated, netdev_wait_allrefs_any() will rebroadcast a 'NETDEV_UNREGISTER' until the netdev's reference count drops to 1. This causes devlink to set the port type back to Ethernet. Fix by only setting and clearing the port type upon 'NETDEV_POST_INIT' and 'NETDEV_PRE_UNINIT', respectively. For all other events, preserve the port type.

If ethtool_ops::get_drvinfo() callback isn't set, ethtool_get_drvinfo() will fill the ethtool_drvinfo::name and ethtool_drvinfo::bus_info fields. However, if the driver provides the callback function, those two fields are not touched. This means that the driver has to fill these itself. Allow the driver to leave those two fields empty and populate them in such case. This way, the driver can rely on the default values for the name and the bus_info. If the driver provides values, do nothing. Signed-off-by:

So while these weren't regression fixes originally, they are now. It's not introducing new beahavior, but simply extending the existing new Devicetree model, to cover remaining platforms: - extend the DeviceTree binding and implementation for the Qualcomm hardware spinlock on some older platforms to follow the style of the newer ones where the DeviceTree representation does not rely on an intermediate syscon node" * tag 'hwlock-v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: dt-bindings: hwlock: qcom-hwspinlock: add syscon to MSM8974 hwspinlock: qcom: add support for MMIO on older SoCs hwspinlock: qcom: correct MMIO max register for newer SoCs dt-bindings: hwlock: qcom-hwspinlock: correct example indentation dt-bindings: hwlock: qcom-hwspinlock: add support for MMIO on older SoCs -

The ndo_start_xmit field in net_device_ops is expected to be of type netdev_tx_t (*ndo_start_xmit)(struct sk_buff *skb, struct net_device *dev). The mismatched return type breaks forward edge kCFI since the underlying function definition does not match the function hook definition. A new warning in clang will catch this at compile time: drivers/net/ethernet/microsoft/mana/mana_en.c:382:21: error: incompatible function pointer types initializing 'netdev_tx_t (*)(struct sk_buff *, struct net_device *)' (aka 'enum netdev_tx (*)(struct sk_buff *, struct net_device *)') with an expression of type 'int (struct sk_buff *, struct net_device *)' [-Werror,-Wincompatible-function-pointer-types-strict] .ndo_start_xmit = mana_start_xmit, ^~~~~~~~~~~~~~~ 1 error generated. The return type of mana_start_xmit should be changed from int to netdev_tx_t.

Antoine Tenart says: ==================== macsec: clear encryption keys in h/w drivers Commit aaab73f8 ("macsec: clear encryption keys from the stack after setting up offload") made sure to clean encryption keys from the stack after setting up offloading but some h/w drivers did a copy of the key which need to be zeroed as well. The MSCC PHY driver can actually be converted not to copy the encryption key at all, but such patch would be quite difficult to backport. I'll send a following up patch doing this in net-next once this series lands. Tested on the MSCC PHY but not on the atlantic NIC. ==================== Link: https://lore.kernel.org/r/20221108153459.811293-1-atenart@kernel.orgSigned-off-by:
