For this Vlad kept TC specific code in tc.c and rep/tc.c and organized non TC code in representors specific files. 3) Eli Cohen adds support for MPLS over UPD encap and decap TC offloads. ==================== Signed-off-by: David S.

2020-05-23net: phy: at803x: fix PHY ID masksMichael Walle
Ever since its first commit 0ca7111a38f05 ("phy: add AT803x driver") the PHY ID mask was set to 0xffffffef. It is unclear to me why this mask was chosen in the first place. Both the AR8031/AR8033 and the AR8035 datasheets mention it is always the given value: - for AR8031/AR8033 its 0x004d/0xd074 - for AR8035 its 0x004d/0xd072 Unfortunately, I don't have a datasheet for the AR8030. Therefore, we leave its PHY ID mask untouched. For the PHYs mentioned before use the handy PHY_ID_MATCH_EXACT() macro. I've tried to contact the author of the initial commit, but received no answer so far. Cc: Matus Ujhelyi <ujhelyi.m@gmail.com> Signed-off-by: Michael Walle <michael@walle.cc> Signed-off-by: David S.

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routing helpers, from Stanislav Fomichev, Andrii Nakryiko and Alan Maguire. 6) Conversion of BPF tracing samples outdated internal BPF loader to use libbpf API instead, from Daniel T. Lee. 7) Follow-up to BPF kernel test infrastructure in order to fix a flake in the XDP selftests,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.

2020-05-22net/mlx5e: Add support for hw decapsulation of MPLS over UDPEli Cohen
MPLS over UDP is supported in hardware by using a packet reformat object with reformat type equal L3_TUNNEL_TO_L2 which both decapsulates the outer L3, L4 and MPLS headers, and allows for setting the L2 headers of the resulting decapsulated packet. For the hardware to operate correctly, the configuration of the firmware must have FLEX_PARSER_PROFILE_ENABLE = 1. Example tc rule: tc filter add dev bareudp0 protocol all prio 1 root flower enc_dst_port \ 6635 enc_src_ip 8.8.8.23 action mpls pop protocol ip pipe \ action pedit ex munge eth dst set 00:11:22:33:44:21 pipe action \ mirred egress redirect dev enp59s0f0_0 We use pedit to set the correct destination MAC. For MPLS over UDP decapsulation to take place, the driver logic requires the following: 1. flower filter added on bareudp device. 2. action mpls pop 3. zero or more pedit munge actions 4. one redirect action Current implementation supports only IPv4 and no VLAN. tc filter show output looks like this: filter protocol all pref 1 flower chain 0 filter protocol all pref 1 flower chain 0 handle 0x1 enc_src_ip 8.8.8.24 enc_dst_port 6635 in_hw in_hw_count 1 action order 1: mpls pop protocol ip pipe index 2 ref 1 bind 1 action order 2: pedit action pipe keys 2 index 1 ref 1 bind 1 key #0 at eth+0: val 00112233 mask 00000000 key #1 at eth+4: val 44210000 mask 0000ffff action order 3: mirred (Egress Redirect to device enp59s0f0_0) stolen index 2 ref 1 bind 1 Signed-off-by: Eli Cohen <eli@mellanox.com> Reviewed-by: Roi Dayan <roid@mellanox.com> Reviewed-by: Eli Britstein <elibr@mellanox.com> Reviewed-by: Vlad Buslov <vladbu@mellanox.com> Reviewed-by: Paul Blakey <paulb@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

2020-05-22net/mlx5e: Add support for hw encapsulation of MPLS over UDPEli Cohen
MPLS over UDP is supported by adding a rule on a representor net device which does tunnel_key set, push mpls and forward to a baredup device. At the hardware level we use a packet_reformat_context object to do the encapsulation of the packet. The resulting packet looks as follows (left side transmitted first): outer L2 | outer IP | UDP | MPLS | inner L3 and data | Example usage: tc filter add dev $rep0 protocol ip prio 1 root flower skip_sw \ action tunnel_key set src_ip 8.8.8.21 dst_ip 8.8.8.24 id 555 \ dst_port 6635 tos 4 ttl 6 csum action mpls push protocol 0x8847 \ label 555 tc 3 action mirred egress redirect dev bareudp0 This is how the filter is shown with tc filter show: tc filter show dev enp59s0f0_0 ingress filter protocol ip pref 1 flower chain 0 filter protocol ip pref 1 flower chain 0 handle 0x1 eth_type ipv4 skip_sw in_hw in_hw_count 1 action order 1: tunnel_key set src_ip 8.8.8.21 dst_ip 8.8.8.24 key_id 555 dst_port 6635 csum tos 0x4 ttl 6 pipe index 1 ref 1 bind 1 action order 2: mpls push protocol mpls_uc label 555 tc 3 ttl 255 pipe index 1 ref 1 bind 1 action order 3: mirred (Egress Redirect to device bareudp0) stolen index 1 ref 1 bind 1 Signed-off-by: Eli Cohen <eli@mellanox.com> Reviewed-by: Roi Dayan <roid@mellanox.com> Reviewed-by: Eli Britstein <elibr@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

Pre-fill all actions with DONT_CARE in flow_rule_alloc(), rather than relying on implicit semantics of zero from kzalloc, so that callers which don't configure action stats themselves (i.e. netfilter) get the correct behaviour by default. Only the kernel's internal API semantics change; the TC uAPI is unaffected. v4: move DONT_CARE setting to flow_rule_alloc() for robustness and simplicity. v3: set DONT_CARE in nft and ct offload. v2: rebased on net-next, removed RFC tags.

First we convert the existing DT bindings for the PERICFG controller to YAML and add a new compatible string for mt8516 variant of it. Then we add the DT bindings for the MAC. Next we do some cleanup of the mediatek ethernet drivers directory. The largest patch in the series adds the actual new driver. The rest of the patches add DT fixups for the boards already supported upstream. v1 -> v2: - add a generic helper for retrieving the net_device associated with given private data - fix several typos in commit messages - remove MTK_MAC_VERSION and don't set the driver version - use NET_IP_ALIGN instead of a magic number (2) but redefine it as it defaults to 0 on arm64 - don't manually turn the carrier off in mtk_mac_enable() - process TX cleanup in napi poll callback - configure pause in the adjust_link callback - use regmap_read_poll_timeout() instead of handcoding the polling - use devres_find() to verify that struct net_device is managed by devres in devm_register_netdev() - add a patch moving all networking devres helpers into net/devres.c - tweak the dma barriers: remove where unnecessary and add comments to the remaining barriers - don't reset internal counters when enabling the NIC - set the net_device's mtu size instead of checking the framesize in ndo_start_xmit() callback - fix a race condition in waking up the netif queue - don't emit log messages on OOM errors - use dma_set_mask_and_coherent() - use eth_hw_addr_random() - rework the receive callback so that we reuse the previous skb if unmapping fails, like we already do if skb allocation fails - rework hash table operations: add proper timeout handling and clear bits when appropriate v2 -> v3: - drop the patch adding priv_to_netdev() and store the netdev pointer in the driver private data - add an additional dma_wmb() after reseting the descriptor in mtk_mac_ring_pop_tail() - check the return value of dma_set_mask_and_coherent() - improve the DT bindings for mtk-eth-mac: make the reg property in the example use single-cell address and size, extend the description of the PERICFG phandle and document the mdio sub-node - add a patch converting the old .txt bindings for PERICFG to yaml - limit reading the DMA memory by storing the mapped addresses in the driver private structure - add a patch documenting the existing networking devres helpers v3 -> v4: - drop the devres patches: they will be sent separately - call netdev_sent_queue() & netdev_completed_queue() where appropriate - don't redefine NET_IP_ALIGN: define a private constant in the driver - fix a couple typos - only disabe/enable the MAC in suspend/resume if netif is running - drop the count field from the ring structure and instead calculate the number of used descriptors from the tail and head indicies - rework the locking used to protect the ring structures from concurrent access: use cheaper spin_lock_bh() and completely disable the internal spinlock used by regmap - rework the interrupt handling to make it more fine-grained: onle re-enable TX and RX interrupts while they're needed, process the stats updates in a workqueue, not in napi context - shrink the code responsible for unmapping and freeing skb memory - rework the barriers as advised by Arnd v4 -> v5: - rename the driver to make it less confusing with the existing mtk_eth_soc ethernet driver - unregister the mdiobus at device's detachment - open-code spin lock calls to avoid calling the _bh variants where unnecessary - limit read-modify-write operations where possible when accessing descriptor memory - use READ_ONCE/WRITE_ONCE when modifying the status and data_ptr descriptor fields ==================== Signed-off-by: David S.
