Vladimir Oltean says: ==================== Bugfixes in Microsemi Ocelot switch driver This is a series of 8 assorted patches for "net", on the drivers for the VSC7514 MIPS switch (Ocelot-1), the VSC9953 PowerPC (Seville), and a few more that are common to all supported devices since they are in the common library portion. ==================== Signed-off-by: -

Currently mscc_ocelot_init_ports() will skip initializing a port when it doesn't have a phy-handle, so the ocelot->ports[port] pointer will be NULL. Take this into consideration when tearing down the driver, and add a new function ocelot_deinit_port() to the switch library, mirror of ocelot_init_port(), which needs to be called by the driver for all ports it has initialized.

mscc_ocelot_probe() is already pretty large and hard to follow. So move the code for parsing ports in a separate function. This makes it easier for the next patch to just call mscc_ocelot_release_ports from the error path of mscc_ocelot_init_ports. Signed-off-by:

The ocelot_port->ts_id is used to: (a) populate skb->cb[0] for matching the TX timestamp in the PTP IRQ with an skb. (b) populate the REW_OP from the injection header of the ongoing skb. Only then is ocelot_port->ts_id incremented. This is a problem because, at least theoretically, another timestampable skb might use the same ocelot_port->ts_id before that is incremented. Normally all transmit calls are serialized by the netdev transmit spinlock, but in this case, ocelot_port_add_txtstamp_skb() is also called by DSA, which has started declaring the NETIF_F_LLTX feature since commit 2b86cb82 ("net: dsa: declare lockless TX feature for slave ports"). So the logic of using and incrementing the timestamp id should be atomic per port. The solution is to use the global ocelot_port->ts_id only while protected by the associated ocelot_port->ts_id_lock. That's where we populate skb->cb[0]. Note that for ocelot, ocelot_port_add_txtstamp_skb is called for the actual skb, but for felix, it is called for the skb's clone. That is something which will also be changed in the future. Signed-off-by: -

The TX-timestampable skb is added late to the ocelot_port->tx_skbs. It is in a race with the TX timestamp IRQ, which checks that queue trying to match the timestamp with the skb by the ts_id. The skb should be added to the queue before the IRQ can fire. Fixes: 4e3b0468 ("net: mscc: PTP Hardware Clock (PHC) support") Signed-off-by:

Tunnel offload info code uses ETHTOOL_MSG_TUNNEL_INFO_GET message type (cmd field in genetlink header) for replies to tunnel info netlink request, i.e. the same value as the request have. This is a problem because we are using two separate enums for userspace to kernel and kernel to userspace message types so that this ETHTOOL_MSG_TUNNEL_INFO_GET (28) collides with ETHTOOL_MSG_CABLE_TEST_TDR_NTF which is what message type 28 means for kernel to userspace messages. As the tunnel info request reached mainline in 5.9 merge window, we should still be able to fix the reply message type without breaking backward compatibility.

This patch sets skb->protocol before transmitting frames on the HDLC device, so that a user listening on the HDLC device with an AF_PACKET socket will see outgoing frames' sll_protocol field correctly set and consistent with that of incoming frames. 1. Control frames in hdlc_cisco and hdlc_ppp When these drivers send control frames, skb->protocol is not set. This value should be set to htons(ETH_P_HDLC), because when receiving control frames, their skb->protocol is set to htons(ETH_P_HDLC). When receiving, hdlc_type_trans in hdlc.h is called, which then calls cisco_type_trans or ppp_type_trans. The skb->protocol of control frames is set to htons(ETH_P_HDLC) so that the control frames can be received by hdlc_rcv in hdlc.c, which calls cisco_rx or ppp_rx to process the control frames. 2. hdlc_fr When this driver sends control frames, skb->protocol is set to internal values used in this driver. When this driver sends data frames (from upper stacked PVC devices), skb->protocol is the same as that of the user data packet being sent on the upper PVC device (for normal PVC devices), or is htons(ETH_P_802_3) (for Ethernet-emulating PVC devices). However, skb->protocol for both control frames and data frames should be set to htons(ETH_P_HDLC), because when receiving, all frames received on the HDLC device will have their skb->protocol set to htons(ETH_P_HDLC). When receiving, hdlc_type_trans in hdlc.h is called, and because this driver doesn't provide a type_trans function in struct hdlc_proto, all frames will have their skb->protocol set to htons(ETH_P_HDLC). The frames are then received by hdlc_rcv in hdlc.c, which calls fr_rx to process the frames (control frames are consumed and data frames are re-received on upper PVC devices).

This driver is a virtual driver stacked on top of Ethernet interfaces. When this driver transmits data on the Ethernet device, the skb->protocol setting is inconsistent with the Ethernet header prepended to the skb. This causes a user listening on the Ethernet interface with an AF_PACKET socket, to see different sll_protocol values for incoming and outgoing frames, because incoming frames would have this value set by parsing the Ethernet header. This patch changes the skb->protocol value for outgoing Ethernet frames, making it consistent with the Ethernet header prepended. This makes a user listening on the Ethernet device with an AF_PACKET socket, to see the same sll_protocol value for incoming and outgoing frames. Cc: Martin Schiller <ms@dev.tdt.de> Signed-off-by:

This patch adds transport ports information for route lookup so that IPsec can select Geneve tunnel traffic to do encryption. This is needed for OVS/OVN IPsec with encrypted Geneve tunnels. This can be tested by configuring a host-host VPN using an IKE daemon and specifying port numbers. For example, for an Openswan-type configuration, the following parameters should be configured on both hosts and IPsec set up as-per normal: $ cat /etc/ipsec.conf conn in ... left=$IP1 right=$IP2 ... leftprotoport=udp/6081 rightprotoport=udp ... conn out ... left=$IP1 right=$IP2 ... leftprotoport=udp rightprotoport=udp/6081 ... The tunnel can then be setup using "ip" on both hosts (but changing the relevant IP addresses): $ ip link add tun type geneve id 1000 remote $IP2 $ ip addr add 192.168.0.1/24 dev tun $ ip link set tun up This can then be tested by pinging from $IP1: $ ping 192.168.0.2 Without this patch the traffic is unencrypted on the wire.

Kfir reported that pmtu exceptions are not created properly for deployments where multipath routes use the same device. After some digging I see 2 compounding problems: 1. ip_route_output_key_hash_rcu is updating the flowi4_oif *after* the route lookup. This is the second use case where this has been a problem (the first is related to use of vti devices with VRF). I can not find any reason for the oif to be changed after the lookup; the code goes back to the start of git. It does not seem logical so remove it. 2. fib_lookups for exceptions do not call fib_select_path to handle multipath route selection based on the hash. The end result is that the fib_lookup used to add the exception always creates it based using the first leg of the route. An example topology showing the problem: | host1 +------+ | eth0 | .209 +------+ | +------+ switch | br0 | +------+ | +---------+---------+ | host2 | host3 +------+ +------+ | eth0 | .250 | eth0 | 192.168.252.252 +------+ +------+ +-----+ +-----+ | vti | .2 | vti | 192.168.247.3 +-----+ +-----+ \ / ================================= tunnels 192.168.247.1/24 for h in host1 host2 host3; do ip netns add ${h} ip -netns ${h} link set lo up ip netns exec ${h} sysctl -wq net.ipv4.ip_forward=1 done ip netns add switch ip -netns switch li set lo up ip -netns switch link add br0 type bridge stp 0 ip -netns switch link set br0 up for n in 1 2 3; do ip -netns switch link add eth-sw type veth peer name eth-h${n} ip -netns switch li set eth-h${n} master br0 up ip -netns switch li set eth-sw netns host${n} name eth0 done ip -netns host1 addr add 192.168.252.209/24 dev eth0 ip -netns host1 link set dev eth0 up ip -netns host1 route add 192.168.247.0/24 \ nexthop via 192.168.252.250 dev eth0 nexthop via 192.168.252.252 dev eth0 ip -netns host2 addr add 192.168.252.250/24 dev eth0 ip -netns host2 link set dev eth0 up ip -netns host2 addr add 192.168.252.252/24 dev eth0 ip -netns host3 link set dev eth0 up ip netns add tunnel ip -netns tunnel li set lo up ip -netns tunnel li add br0 type bridge ip -netns tunnel li set br0 up for n in $(seq 11 20); do ip -netns tunnel addr add dev br0 192.168.247.${n}/24 done for n in 2 3 do ip -netns tunnel link add vti${n} type veth peer name eth${n} ip -netns tunnel link set eth${n} mtu 1360 master br0 up ip -netns tunnel link set vti${n} netns host${n} mtu 1360 up ip -netns host${n} addr add dev vti${n} 192.168.247.${n}/24 done ip -netns tunnel ro add default nexthop via 192.168.247.2 nexthop via 192.168.247.3 ip netns exec host1 ping -M do -s 1400 -c3 -I 192.168.252.209 192.168.247.11 ip netns exec host1 ping -M do -s 1400 -c3 -I 192.168.252.209 192.168.247.15 ip -netns host1 ro ls cache Before this patch the cache always shows exceptions against the first leg in the multipath route; 192.168.252.250 per this example.

For AF_XDP sockets, there was a discrepancy between the number of of pinned pages and the size of the umem region. The size of the umem region is used to validate the AF_XDP descriptor addresses. The logic that pinned the pages covered by the region only took whole pages into consideration, creating a mismatch between the size and pinned pages. A user could then pass AF_XDP addresses outside the range of pinned pages, but still within the size of the region, crashing the kernel. This change correctly calculates the number of pages to be pinned. Further, the size check for the aligned mode is simplified. Now the code simply checks if the size is divisible by the chunk size.
