git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: - Add redirect_neigh() BPF packet redirect helper, allowing to limit stack traversal in common container configs and improving TCP back-pressure. Daniel reports ~10Gbps => ~15Gbps single stream TCP performance gain. - Expand netlink policy support and improve policy export to user space. (Ge)netlink core performs request validation according to declared policies. Expand the expressiveness of those policies (min/max length and bitmasks). Allow dumping policies for particular commands. This is used for feature discovery by user space (instead of kernel version parsing or trial and error). - Support IGMPv3/MLDv2 multicast listener discovery protocols in bridge. - Allow more than 255 IPv4 multicast interfaces. - Add support for Type of Service (ToS) reflection in SYN/SYN-ACK packets of TCPv6. - In Multi-patch TCP (MPTCP) support concurrent transmission of data on multiple subflows in a load balancing scenario. Enhance advertising addresses via the RM_ADDR/ADD_ADDR options. - Support SMC-Dv2 version of SMC, which enables multi-subnet deployments. - Allow more calls to same peer in RxRPC. - Support two new Controller Area Network (CAN) protocols - CAN-FD and ISO 15765-2:2016. - Add xfrm/IPsec compat layer, solving the 32bit user space on 64bit kernel problem. - Add TC actions for implementing MPLS L2 VPNs. - Improve nexthop code - e.g. handle various corner cases when nexthop objects are removed from groups better, skip unnecessary notifications and make it easier to offload nexthops into HW by converting to a blocking notifier. - Support adding and consuming TCP header options by BPF programs, opening the doors for easy experimental and deployment-specific TCP option use. - Reorganize TCP congestion control (CC) initialization to simplify life of TCP CC implemented in BPF. - Add support for shipping BPF programs with the kernel and loading them early on boot via the User Mode Driver mechanism, hence reusing all the user space infra we have. - Support sleepable BPF programs, initially targeting LSM and tracing. - Add bpf_d_path() helper for returning full path for given 'struct path'. - Make bpf_tail_call compatible with bpf-to-bpf calls. - Allow BPF programs to call map_update_elem on sockmaps. - Add BPF Type Format (BTF) support for type and enum discovery, as well as support for using BTF within the kernel itself (current use is for pretty printing structures). - Support listing and getting information about bpf_links via the bpf syscall. - Enhance kernel interfaces around NIC firmware update. Allow specifying overwrite mask to control if settings etc. are reset during update; report expected max time operation may take to users; support firmware activation without machine reboot incl. limits of how much impact reset may have (e.g. dropping link or not). - Extend ethtool configuration interface to report IEEE-standard counters, to limit the need for per-vendor logic in user space. - Adopt or extend devlink use for debug, monitoring, fw update in many drivers (dsa loop, ice, ionic, sja1105, qed, mlxsw, mv88e6xxx, dpaa2-eth). - In mlxsw expose critical and emergency SFP module temperature alarms. Refactor port buffer handling to make the defaults more suitable and support setting these values explicitly via the DCBNL interface. - Add XDP support for Intel's igb driver. - Support offloading TC flower classification and filtering rules to mscc_ocelot switches. - Add PTP support for Marvell Octeontx2 and PP2.2 hardware, as well as fixed interval period pulse generator and one-step timestamping in dpaa-eth. - Add support for various auth offloads in WiFi APs, e.g. SAE (WPA3) offload. - Add Lynx PHY/PCS MDIO module, and convert various drivers which have this HW to use it. Convert mvpp2 to split PCS. - Support Marvell Prestera 98DX3255 24-port switch ASICs, as well as 7-port Mediatek MT7531 IP. - Add initial support for QCA6390 and IPQ6018 in ath11k WiFi driver, and wcn3680 support in wcn36xx. - Improve performance for packets which don't require much offloads on recent Mellanox NICs by 20% by making multiple packets share a descriptor entry. - Move chelsio inline crypto drivers (for TLS and IPsec) from the crypto subtree to drivers/net. Move MDIO drivers out of the phy directory. - Clean up a lot of W=1 warnings, reportedly the actively developed subsections of networking drivers should now build W=1 warning free. - Make sure drivers don't use in_interrupt() to dynamically adapt their code. Convert tasklets to use new tasklet_setup API (sadly this conversion is not yet complete). * tag 'net-next-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (2583 commits) Revert "bpfilter: Fix build error with CONFIG_BPFILTER_UMH" net, sockmap: Don't call bpf_prog_put() on NULL pointer bpf, selftest: Fix flaky tcp_hdr_options test when adding addr to lo bpf, sockmap: Add locking annotations to iterator netfilter: nftables: allow re-computing sctp CRC-32C in 'payload' statements net: fix pos incrementment in ipv6_route_seq_next net/smc: fix invalid return code in smcd_new_buf_create() net/smc: fix valid DMBE buffer sizes net/smc: fix use-after-free of delayed events bpfilter: Fix build error with CONFIG_BPFILTER_UMH cxgb4/ch_ipsec: Replace the module name to ch_ipsec from chcr net: sched: Fix suspicious RCU usage while accessing tcf_tunnel_info bpf: Fix register equivalence tracking. rxrpc: Fix loss of final ack on shutdown rxrpc: Fix bundle counting for exclusive connections netfilter: restore NF_INET_NUMHOOKS ibmveth: Identify ingress large send packets. ibmveth: Switch order of ibmveth_helper calls. cxgb4: handle 4-tuple PEDIT to NAT mode translation selftests: Add VRF route leaking tests ...

2020-10-05net: dsa: propagate switchdev vlan_filtering prepare phase to driversVladimir Oltean
A driver may refuse to enable VLAN filtering for any reason beyond what the DSA framework cares about, such as: - having tc-flower rules that rely on the switch being VLAN-aware - the particular switch does not support VLAN, even if the driver does (the DSA framework just checks for the presence of the .port_vlan_add and .port_vlan_del pointers) - simply not supporting this configuration to be toggled at runtime Currently, when a driver rejects a configuration it cannot support, it does this from the commit phase, which triggers various warnings in switchdev. So propagate the prepare phase to drivers, to give them the ability to refuse invalid configurations cleanly and avoid the warnings. Since we need to modify all function prototypes and check for the prepare phase from within the drivers, take that opportunity and move the existing driver restrictions within the prepare phase where that is possible and easy.

2020-10-02net: mscc: ocelot: create TCAM skeleton from tc filter chainsVladimir Oltean
For Ocelot switches, there are 2 ingress pipelines for flow offload rules: VCAP IS1 (Ingress Classification) and IS2 (Security Enforcement). IS1 and IS2 support different sets of actions. The pipeline order for a packet on ingress is: Basic classification -> VCAP IS1 -> VCAP IS2 Furthermore, IS1 is looked up 3 times, and IS2 is looked up twice (each TCAM entry can be configured to match only on the first lookup, or only on the second, or on both etc). Because the TCAMs are completely independent in hardware, and because of the fixed pipeline, we actually have very limited options when it comes to offloading complex rules to them while still maintaining the same semantics with the software data path. This patch maps flow offload rules to ingress TCAMs according to a predefined chain index number. There is going to be a script in selftests that clarifies the usage model. There is also an egress TCAM (VCAP ES0, the Egress Rewriter), which is modeled on top of the default chain 0 of the egress qdisc, because it doesn't have multiple lookups. Suggested-by: Allan W.

2020-10-02net: mscc: ocelot: introduce conversion helpers between port and netdevVladimir Oltean
Since the mscc_ocelot_switch_lib is common between a pure switchdev and a DSA driver, the procedure of retrieving a net_device for a certain port index differs, as those are registered by their individual front-ends. Up to now that has been dealt with by always passing the port index to the switch library, but now, we're going to need to work with net_device pointers from the tc-flower offload, for things like indev, or mirred. It is not desirable to refactor that, so let's make sure that the flower offload core has the ability to translate between a net_device and a port index properly.

2020-09-29net: mscc: ocelot: automatically detect VCAP constantsVladimir Oltean
The numbers in struct vcap_props are not intuitive to derive, because they are not a straightforward copy-and-paste from the reference manual but instead rely on a fairly detailed level of understanding of the layout of an entry in the TCAM and in the action RAM. For this reason, bugs are very easy to introduce here. Ease the work of hardware porters and read from hardware the constants that were exported for this particular purpose. Note that this implies that struct vcap_props can no longer be const. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2020-09-29net: mscc: ocelot: generalize existing code for VCAPVladimir Oltean
In the Ocelot switches there are 3 TCAMs: VCAP ES0, IS1 and IS2, which have the same configuration interface, but different sets of keys and actions. The driver currently only supports VCAP IS2. In preparation of VCAP IS1 and ES0 support, the existing code must be generalized to work with any VCAP. In that direction, we should move the structures that depend upon VCAP instantiation, like vcap_is2_keys and vcap_is2_actions, out of struct ocelot and into struct vcap_props .keys and .actions, a structure that is replicated 3 times, once per VCAP. We'll pass that structure as an argument to each function that does the key and action packing - only the control logic needs to distinguish between ocelot->vcap[VCAP_IS2] or IS1 or ES0. Another change is to make use of the newly introduced ocelot_target_read and ocelot_target_write API, since the 3 VCAPs have the same registers but put at different addresses.

2020-09-29net: mscc: ocelot: introduce a new ocelot_target_{read,write} APIVladimir Oltean
There are some targets (register blocks) in the Ocelot switch that are instantiated more than once. For example, the VCAP IS1, IS2 and ES0 blocks all share the same register layout for interacting with the cache for the TCAM and the action RAM. For the VCAPs, the procedure for servicing them is actually common. We just need an API specifying which VCAP we are talking to, and we do that via these raw ocelot_target_read and ocelot_target_write accessors. In plain ocelot_read, the target is encoded into the register enum itself: u16 target = reg >> TARGET_OFFSET; For the VCAPs, the registers are currently defined like this: enum ocelot_reg { [...] S2_CORE_UPDATE_CTRL = S2 << TARGET_OFFSET, S2_CORE_MV_CFG, S2_CACHE_ENTRY_DAT, S2_CACHE_MASK_DAT, S2_CACHE_ACTION_DAT, S2_CACHE_CNT_DAT, S2_CACHE_TG_DAT, [...] }; which is precisely what we want to avoid, because we'd have to duplicate the same register map for S1 and for S0, and then figure out how to pass VCAP instance-specific registers to the ocelot_read calls (basically another lookup table that undoes the effect of shifting with TARGET_OFFSET). So for some targets, propose a more raw API, similar to what is currently done with ocelot_port_readl and ocelot_port_writel. Those targets can only be accessed with ocelot_target_{read,write} and not with ocelot_{read,write} after the conversion, which is fine. The VCAP registers are not actually modified to use this new API as of this patch. They will be modified in the next one.

2020-09-26net: dsa: tag_ocelot: use a short prefix on both ingress and egressVladimir Oltean
There are 2 goals that we follow: - Reduce the header size - Make the header size equal between RX and TX The issue that required long prefix on RX was the fact that the ocelot DSA tag, being put before Ethernet as it is, would overlap with the area that a DSA master uses for RX filtering (destination MAC address mainly). Now that we can ask DSA to put the master in promiscuous mode, in theory we could remove the prefix altogether and call it a day, but it looks like we can't. Using no prefix on ingress, some packets (such as ICMP) would be received, while others (such as PTP) would not be received. This is because the DSA master we use (enetc) triggers parse errors ("MAC rx frame errors") presumably because it sees Ethernet frames with a bad length. And indeed, when using no prefix, the EtherType (bytes 12-13 of the frame, bits 96-111) falls over the REW_VAL field from the extraction header, aka the PTP timestamp. When turning the short (32-bit) prefix on, the EtherType overlaps with bits 64-79 of the extraction header, which are a reserved area transmitted as zero by the switch. The packets are not dropped by the DSA master with a short prefix. Actually, the frames look like this in tcpdump (below is a PTP frame, with an extra dsa_8021q tag - dadb 0482 - added by a downstream sja1105). 89:0c:a9:f2:01:00 > 88:80:00:0a:00:1d, 802.3, length 0: LLC, \ dsap Unknown (0x10) Individual, ssap ProWay NM (0x0e) Response, \ ctrl 0x0004: Information, send seq 2, rcv seq 0, \ Flags [Response], length 78 0x0000: 8880 000a 001d 890c a9f2 0100 0000 100f ................ 0x0010: 0400 0000 0180 c200 000e 001f 7b63 0248 ............{c.H 0x0020: dadb 0482 88f7 1202 0036 0000 0000 0000 .........6...... 0x0030: 0000 0000 0000 0000 0000 001f 7bff fe63 ............{..c 0x0040: 0248 0001 1f81 0500 0000 0000 0000 0000 .H.............. 0x0050: 0000 0000 0000 0000 0000 0000 ............ So the short prefix is our new default: we've shortened our RX frames by 12 octets, increased TX by 4, and headers are now equal between RX and TX. Note that we still need promiscuous mode for the DSA master to not drop it. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-09-26net: mscc: ocelot: move NPI port configuration to DSAVladimir Oltean
Remove the ocelot_configure_cpu() function, which was in fact bringing up 2 ports: the CPU port module, which both switchdev and DSA have, and the NPI port, which only DSA has. The (non-Ethernet) CPU port module is at a fixed index in the analyzer, whereas the NPI port is selected through the "ethernet" property in the device tree. Therefore, the function to set up an NPI port is DSA-specific, so we move it there, simplifying the ocelot switch library a little bit.

Currently, ocelot switchdev passes the skb directly to the function that enqueues it to the list of skb's awaiting a TX timestamp. Whereas the felix DSA driver first clones the skb, then passes the clone to this queue. This matters because in the case of felix, the common IRQ handler, which is ocelot_get_txtstamp(), currently clones the clone, and frees the original clone. This is useless and can be simplified by using skb_complete_tx_timestamp() instead of skb_tstamp_tx().

2020-09-18net: mscc: ocelot: deinitialize only initialized portsVladimir Oltean
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.

2020-09-18net: mscc: ocelot: add locking for the port TX timestamp IDVladimir Oltean
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 2b86cb829976 ("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.

2020-07-13net: dsa: felix: create a template for the DSA tags on xmitVladimir Oltean
With this patch we try to kill 2 birds with 1 stone. First of all, some switches that use tag_ocelot.c don't have the exact same bitfield layout for the DSA tags. The destination ports field is different for Seville VSC9953 for example. So the choices are to either duplicate tag_ocelot.c into a new tag_seville.c (sub-optimal) or somehow take into account a supposed ocelot->dest_ports_offset when packing this field into the DSA injection header (again not ideal). Secondly, tag_ocelot.c already needs to memset a 128-bit area to zero and call some packing() functions of dubious performance in the fastpath. And most of the values it needs to pack are pretty much constant (BYPASS=1, SRC_PORT=CPU, DEST=port index). So it would be good if we could improve that. The proposed solution is to allocate a memory area per port at probe time, initialize that with the statically defined bits as per chip hardware revision, and just perform a simpler memcpy in the fastpath. Other alternatives have been analyzed, such as: - Create a separate tag_seville.c: too much code duplication for just 1 bit field difference. - Create a separate DSA_TAG_PROTO_SEVILLE under tag_ocelot.c, just like tag_brcm.c, which would have a separate .xmit function. Again, too much code duplication for just 1 bit field difference. - Allocate the template from the init function of the tag_ocelot.c module, instead of from the driver: couldn't figure out a method of accessing the correct port template corresponding to the correct tagger in the .xmit function.

Currently Felix and Ocelot share the same bit layout in these per-port registers, but Seville does not. So we need reg_fields for that. Actually since these are per-port registers, we need to also specify the number of ports, and register size per port, and use the regmap API for multiple ports. There's a more subtle point to be made about the other 2 register fields: - QSYS_SWITCH_PORT_MODE_SCH_NEXT_CFG - QSYS_SWITCH_PORT_MODE_INGRESS_DROP_MODE which we are not writing any longer, for 2 reasons: - Using the previous API (ocelot_write_rix), we were only writing 1 for Felix and Ocelot, which was their hardware-default value, and which there wasn't any intention in changing. - In the case of SCH_NEXT_CFG, in fact Seville does not have this register field at all, and therefore, if we want to have common code we would be required to not write to it.

At the moment, there are some minimal register differences between VSC7514 Ocelot and VSC9959 Felix. To be precise, the PCS1G registers are missing from Felix because it was integrated with an NXP PCS. But with VSC9953 Seville (not yet introduced), the register differences are more pronounced. The MAC registers are located at different offsets within the DEV_GMII target. So we need to refactor the driver to keep a regmap even for per-port registers. The callers of the ocelot_port_readl and ocelot_port_writel were kept unchanged, only the implementation is now more generic.
