2023-08-02net: tun: change tun_alloc_skb() to allow bigger paged allocationsEric Dumazet
tun_alloc_skb() is currently calling sock_alloc_send_pskb() forcing order-0 page allocations. Switch to PAGE_ALLOC_COSTLY_ORDER, to increase max allocation size by 8x. Also add logic to increase the linear part if needed.

2023-08-02net: allow alloc_skb_with_frags() to allocate bigger packetsEric Dumazet
Refactor alloc_skb_with_frags() to allow bigger packets allocations. Instead of assuming that only order-0 allocations will be attempted, use the caller supplied max order. v2: try harder to use high-order pages, per Willem feedback.

2023-08-02net/mlx5e: Make TC and IPsec offloads mutually exclusive on a netdevJianbo Liu
For IPsec packet offload mode, the order of TC offload and IPsec offload on the same netdevice is not aligned with the order in the non-offload software. For example, for RX, the software performs TC first and then IPsec transformation, but the implementation for offload does that in the opposite way. To resolve the difference for now, either IPsec offload or TC offload, not both, is allowed for a specific interface.

2023-08-02net/mlx5e: Modify and restore TC rules for IPSec TX rulesJianbo Liu
After IPsec policy/state TX rules are added, any TC flow rule, which forwards packets to uplink, is modified to forward to IPsec TX tables. As these tables are destroyed dynamically, whenever there is no reference to them, the destinations of this kind of rules must be restored to uplink. There is a special case for packet encapsulation, as the packet_reformat_id in the extended destination is used to reformat packets, but only for the VPORT destination. To forward packet to IPsec table and do encapsulation in one FTE, move the packet_reformat_id to flow context, instead of using the extended destination. As a limitation, multiple encapsulations with table forwarding, and one together with other VPORT destinations, are not allowed, so add a check when offloading TC rules. TC rules are not allowed before IPsec TX rule is added, so only need to restore TC rules after flush IPSec TX rules. As they are saved in the vport_rep rhashtables, we walk all the rules in the rhashtables, and find TC rules with destinations pointing to IPsec tables, and modify them one by one. To avoid concurrent issue, this handling is done under the protection of eswitch mode_lock.

2023-08-02net/mlx5e: Support IPsec packet offload for TX in switchdev modeJianbo Liu
The IPsec encryption is done at the last, so add new prio for IPsec offload in FDB, and put it just lower than the slow path prio and higher than the per-vport prio. Three levels are added for TX. The first one is for ip xfrm policy. The sa table is created in the second level for ip xfrm state. The status table is created at the last to count the number of packets encrypted. The rules, which forward packets to uplink, are changed to forward them to IPsec TX tables first. These rules are restored after those tables are destroyed, which is done immediately when there is no reference to them, just as what does in legacy mode. The support for slow path is added here, by refreshing uplink's channels. But, the handling for TC fast path, which is more complicated, will be added later. Besides, reg c4 is used instead to match reqid.

MD Danish Anwar says: ==================== Introduce ICSSG based ethernet Driver The Programmable Real-time Unit and Industrial Communication Subsystem Gigabit (PRU_ICSSG) is a low-latency microcontroller subsystem in the TI SoCs. This subsystem is provided for the use cases like the implementation of custom peripheral interfaces, offloading of tasks from the other processor cores of the SoC, etc. The subsystem includes many accelerators for data processing like multiplier and multiplier-accumulator. It also has peripherals like UART, MII/RGMII, MDIO, etc. Every ICSSG core includes two 32-bit load/store RISC CPU cores called PRUs. The above features allow it to be used for implementing custom firmware based peripherals like ethernet. This series adds the YAML documentation and the driver with basic EMAC support for TI AM654 Silicon Rev 2 SoC with the PRU_ICSSG Sub-system. running dual-EMAC firmware. This currently supports basic EMAC with 1Gbps and 100Mbps link. 10M and half-duplex modes are not yet supported because they require the support of an IEP, which will be added later. Advanced features like switch-dev and timestamping will be added later. This is the v13 of the patch series [v1]. This version of the patchset addresses comments made on v12. There series doesn't have any dependency. Changes from v12 to v13 : *) Rebased the series on latest net-next. *) Addressed Jakub's comments on ndo_xmit API. Now we will only stop queues based on occupancy not on dma errors. *) Removed limiting the number of serviced packets to budget for Tx NAPI. Now Tx NAPI will keep servicing packets. *) Removed netif_running() check when packet arrives. *) Introduced prototypes of APIs in the same patch where these APIs are added. Dropped __maybe_unused tags as compiler only cares about prototypes existing, not whether actual callers are in place. Now prototypes of these APIs are present in the same patch where they are introduced but thes APIs are called later (in patch 6). Changes from v11 to v12 : *) Rebased the series on latest net-next. *) Addressed Jakub's comments on ndo_xmit API. *) Added hooks to .get_rmon_stats for the driver. Now tx / rx bucket size and frame counts per bucket will be fetched by ethtool_rmon_stats instead of ethtool -S. *) Added __maybe_unused tags to unused config and classifier APIs in patch 2,3 and 4. These tags are later removed in patch 6. Changes from v10 to v11 : *) Rebased the series on latest net-next. *) Split the ICSSG driver introduction patch into 9 different patches as asked by Jakub. *) Introduced new patch(patch 8/10) to dump Standard network interface staticstics via ndo_get_stats64. Now certain stats that are reported by ICSSG hardware and are also part of struct rtnl_link_stats64, will be reported by ndo_get_stats64. While other stats that are not part of the struct rtnl_link_stats64 will be reported by ethtool -S. These stats are not duplicated. Changes from v9 to v10 : *) Rebased the series on latest net-next. *) Moved 'ndev prueth->emac[mac] == emac' assignment to the end of function prueth_netdev_init(). *) In unsupported phy_mode switch case instead of returning -EINVAL, store the error code in ret and 'goto free' Changes from v8 to v9 : *) Rebased the series on latest net-next. *) Fixed smatch and sparse warnings as pointed by Simon. *) Fixed leaky ndev in prueth_netdev_init() as asked by Simon.

2023-08-02net: ti: icssg-prueth: Add ICSSG StatsMD Danish Anwar
Add icssg_stats.c to help dump, icssg related driver statistics. ICSSG has hardware registers for providing statistics like total rx bytes, total tx bytes, etc. These registers are of 32 bits and hence in case of 1G link, they overflows in around 32 seconds. The behaviour of these registers is such that they don't roll back to 0 after overflow but rather stay at UINT_MAX. These registers support a feature where the value written to them is subtracted from the register. This feature can be utilized to fix the overflowing of stats. This solution uses a Workqueues based solution where a function gets called before the registers overflow (every 25 seconds in 1G link, 25000 seconds in 100M link), this function saves the register values in local variables and writes the last read value to the register. So any update during the read will be taken care of. Signed-off-by: MD Danish Anwar <danishanwar@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2023-08-02net: ti: icssg-prueth: Add ICSSG ethernet driverRoger Quadros
This is the Ethernet driver for TI AM654 Silicon rev. 2 with the ICSSG PRU Sub-system running dual-EMAC firmware. The Programmable Real-time Unit and Industrial Communication Subsystem Gigabit (PRU_ICSSG) is a low-latency microcontroller subsystem in the TI SoCs. This subsystem is provided for the use cases like implementation of custom peripheral interfaces, offloading of tasks from the other processor cores of the SoC, etc. Every ICSSG core has two Programmable Real-Time Unit(PRUs), two auxiliary Real-Time Transfer Unit (RT_PRUs), and two Transmit Real-Time Transfer Units (TX_PRUs). Each one of these runs its own firmware. Every ICSSG core has two MII ports connect to these PRUs and also a MDIO port. The cores can run different firmwares to support different protocols and features like switch-dev, timestamping, etc. It uses System DMA to transfer and receive packets and shared memory register emulation between the firmware and driver for control and configuration. This patch adds support for basic EMAC functionality with 1Gbps and 100Mbps link speed. 10M and half duplex mode are not supported currently as they require IEP, the support for which will be added later. Support for switch-dev, timestamp, etc. will be added later by subsequent patch series.

Neil Armstrong says: ==================== net: ethernet: dwmac: oxnas glue removal With [1] removing MPCore SMP support, this makes the OX820 barely usable, associated with a clear lack of maintainance, development and migration to dt-schema it's clear that Linux support for OX810 and OX820 should be removed. In addition, the OX810 hasn't been booted for years and isn't even present in an ARM config file. For the OX820, lack of USB and SATA support makes the platform not usable in the current Linux support and relies on off-tree drivers hacked from the vendor (defunct for years) sources. The last users are in the OpenWRT distribution, and today's removal means support will still be in stable 6.1 LTS kernel until end of 2026. If someone wants to take over the development even with lack of SMP, I'll be happy to hand off maintainance. It has been a fun time adding support for this architecture, but it's time to get over!

2023-08-02Merge branch 'selftests-mlxsw'David S. Miller
Petr Machata says: ==================== selftests: New selftests for out-of-order-operations patches in mlxsw In the past, the mlxsw driver made the assumption that the user applies configuration in a bottom-up manner. Thus netdevices needed to be added to the bridge before IP addresses were configured on that bridge or SVI added on top of it, because whatever happened before a netdevice was mlxsw upper was generally ignored by mlxsw. Recently, several patch series were pushed to introduce the bookkeeping and replays necessary to offload the full state, not just the immediate configuration step. In this patchset, introduce new selftests that directly exercise the out of order code paths in mlxsw. - Patch #1 adds new tests into the existing selftest router_bridge.sh. - Patches #2-#5 add new generic selftests. - Patches #6-#8 add new mlxsw-specific selftests. ==================== Signed-off-by: David S.
