2020-10-20netsec: ignore 'phy-mode' device property on ACPI systemsArd Biesheuvel
Since commit bbc4d71d63549bc ("net: phy: realtek: fix rtl8211e rx/tx delay config"), the Realtek PHY driver will override any TX/RX delay set by hardware straps if the phy-mode device property does not match. This is causing problems on SynQuacer based platforms (the only SoC that incorporates the netsec hardware), since many were built with this Realtek PHY, and shipped with firmware that defines the phy-mode as 'rgmii', even though the PHY is configured for TX and RX delay using pull-ups. From the driver's perspective, we should not make any assumptions in the general case that the PHY hardware does not require any initial configuration. However, the situation is slightly different for ACPI boot, since it implies rich firmware with AML abstractions to handle hardware details that are not exposed to the OS. So in the ACPI case, it is reasonable to assume that the PHY comes up in the right mode, regardless of whether the mode is set by straps, by boot time firmware or by AML executed by the ACPI interpreter. So let's ignore the 'phy-mode' device property when probing the netsec driver in ACPI mode, and hardcode the mode to PHY_INTERFACE_MODE_NA, which should work with any PHY provided that it is configured by the time the driver attaches to it. While at it, document that omitting the mode is permitted for DT probing as well, by setting the phy-mode DT property to the empty string.

2020-10-19r8169: fix operation under forced interrupt threadingHeiner Kallweit
For several network drivers it was reported that using __napi_schedule_irqoff() is unsafe with forced threading. One way to fix this is switching back to __napi_schedule, but then we lose the benefit of the irqoff version in general. As stated by Eric it doesn't make sense to make the minimal hard irq handlers in drivers using NAPI a thread. Therefore ensure that the hard irq handler is never thread-ified.

Ian reports that after upgrade from v5.8.14 to v5.9 only one of his 4 ixgbe netdevs appear in the system. Quoting the comment on ixgbe_x550em_a_has_mii(): * Returns true if hw points to lowest numbered PCI B:D.F x550_em_a device in * the SoC. There are up to 4 MACs sharing a single MDIO bus on the x550em_a, * but we only want to register one MDIO bus. This matches the symptoms, since the return value from ixgbe_mii_bus_init() is no longer ignored we need to handle the higher ports of x550em without an error.

2020-10-16Merge branch 'dynamic_sg' into rdma.git for-nextJason Gunthorpe
From Maor Gottlieb says: ==================== This series extends __sg_alloc_table_from_pages to allow chaining of new pages to an already initialized SG table. This allows for drivers to utilize the optimization of merging contiguous pages without a need to pre allocate all the pages and hold them in a very large temporary buffer prior to the call to SG table initialization. The last patch changes the Infiniband core to use the new API. It removes duplicate functionality from the code and benefits from the optimization of allocating dynamic SG table from pages. In huge pages system of 2MB page size, without this change, the SG table would contain x512 SG entries. ==================== * branch 'dynamic_sg': RDMA/umem: Move to allocate SG table from pages lib/scatterlist: Add support in dynamic allocation of SG table from pages tools/testing/scatterlist: Show errors in human readable form tools/testing/scatterlist: Rejuvenate bit-rotten test

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.

2020-10-14cxgb4: handle 4-tuple PEDIT to NAT mode translationHerat Ramani
The 4-tuple NAT offload via PEDIT always overwrites all the 4-tuple fields even if they had not been explicitly enabled. If any fields in the 4-tuple are not enabled, then the hardware overwrites the disabled fields with zeros, instead of ignoring them. So, add a parser that can translate the enabled 4-tuple PEDIT fields to one of the NAT mode combinations supported by the hardware and hence avoid overwriting disabled fields to 0. Any rule with unsupported NAT mode combination is rejected. Signed-off-by: Herat Ramani <herat@chelsio.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2020-10-13macb: support the two tx descriptors on at91rm9200Willy Tarreau
The at91rm9200 variant used by a few chips including the MSC313 supports two Tx descriptors (one frame being serialized and another one queued). However the driver only implemented a single one, which adds a dead time after each transfer to receive and process the interrupt and wake the queue up, preventing from reaching line rate. This patch implements a very basic 2-deep queue to address this limitation. The tests run on a Breadbee board equipped with an MSC313E show that at 1 GHz, HTTP traffic on medium-sized objects (45kB) was limited to exactly 50 Mbps before this patch, and jumped to 76 Mbps with this patch. And tests on a single TCP stream with an MTU of 576 jump from 10kpps to 15kpps. With 1500 byte packets it's now possible to reach line rate versus 75 Mbps before.

2020-10-13macb: prepare at91 to use a 2-frame TX queueWilly Tarreau
The RM9200 supports one frame being sent while another one is waiting in queue. This avoids the dead time that follows the emission of a frame and which prevents one from reaching line speed. Right now the driver supports only a single skb, so we'll first replace the rm9200-specific skb info with an array of two macb_tx_skb (already used by other drivers). This patch only moves the skb_length to txq[0].size and skb_physaddr to skb[0].mapping but doesn't perform any other change. It already uses [desc] in order to minimize future changes.

2020-10-12net/mlx5e: IPsec: Add Connect-X IPsec Tx data path offloadRaed Salem
In the TX data path, spot packets with xfrm stack IPsec offload indication. Fill Software-Parser segment in TX descriptor so that the hardware may parse the ESP protocol, and perform TX checksum offload on the inner payload. Support GSO, by providing the trailer data and ICV placeholder so HW can fill it post encryption operation. Padding alignment cannot be performed in HW (ConnectX-6Dx) due to a bug. Software can overcome this limitation by adding NETIF_F_HW_ESP to the gso_partial_features field in netdev so the packets being aligned by the stack. l4_inner_checksum cannot be offloaded by HW for IPsec tunnel type packet. Note that for GSO SKBs, the stack does not include an ESP trailer, unlike the non-GSO case. Below is the iperf3 performance report on two server of 24 cores Intel(R) Xeon(R) CPU E5-2620 v3 @ 2.40GHz with ConnectX6-DX. All the bandwidth test uses iperf3 TCP traffic with packet size 128KB. Each tunnel uses one iperf3 stream with one thread (option -P1).
