Pull networking fixes from Jakub Kicinski: "Including fixes from bluetooth, netfilter, WiFi.
Feels like an up-tick in regression fixes, mostly for older releases. The hfsc fix, tcp_disconnect() and Intel WWAN fixes stand out as fairly clear-cut user reported regressions. The mlx5 DMA bug was causing strife for 390x folks. The fixes themselves are not particularly scary, tho. No open investigations / outstanding reports at the time of writing.
Current release - regressions:
- eth: mlx5: perform DMA operations in the right locations, make devices usable on s390x, again
- sched: sch_hfsc: upgrade 'rt' to 'sc' when it becomes a inner curve, previous fix of rejecting invalid config broke some scripts
- rfkill: reduce data->mtx scope in rfkill_fop_open, avoid deadlock
- revert "ethtool: Fix mod state of verbose no_mask bitset", needs more work
Current release - new code bugs:
- tcp: fix listen() warning with v4-mapped-v6 address
Previous releases - regressions:
- tcp: allow tcp_disconnect() again when threads are waiting, it was denied to plug a constant source of bugs but turns out .NET depends on it
- eth: mlx5: fix double-free if buffer refill fails under OOM
- revert "net: wwan: iosm: enable runtime pm support for 7560", it's causing regressions and the WWAN team at Intel disappeared
- tcp: tsq: relax tcp_small_queue_check() when rtx queue contains a single skb, fix single-stream perf regression on some devices
Previous releases - always broken:
- Bluetooth: - fix issues in legacy BR/EDR PIN code pairing - correctly bounds check and pad HCI_MON_NEW_INDEX name
- netfilter: - more fixes / follow ups for the large "commit protocol" rework, which went in as a fix to 6.5 - fix null-derefs on netlink attrs which user may not pass in
- tcp: fix excessive TLP and RACK timeouts from HZ rounding (bless Debian for keeping HZ=250 alive)
- net: more strict VIRTIO_NET_HDR_GSO_UDP_L4 validation, prevent letting frankenstein UDP super-frames from getting into the stack
- net: fix interface altnames when ifc moves to a new namespace
- eth: qed: fix the size of the RX buffers
- mptcp: avoid sending RST when closing the initial subflow"

Merge branch 'iep-drver-timestamping-support'
MD Danish Anwar says:
==================== Introduce IEP driver and packet timestamping support
This series introduces Industrial Ethernet Peripheral (IEP) driver to support timestamping of ethernet packets and thus support PTP and PPS for PRU ICSSG ethernet ports.
This series also adds 10M full duplex support for ICSSG ethernet driver.
There are two IEP instances. IEP0 is used for packet timestamping while IEP1 is used for 10M full duplex support.
This is v7 of the series [v1]. It addresses comments made on [v6]. This series is based on linux-next(#next-20230823).
Changes from v6 to v7: *) Dropped blank line in example section of patch 1. *) Patch 1 previously had three examples, removed two examples and kept only one example as asked by Krzysztof. *) Added Jacob Keller's RB tag in patch 5. *) Dropped Roger's RB tags from the patches that he has authored (Patch 3 and 4)
Changes from v5 to v6: *) Added description of IEP in commit messages of patch 2 as asked by Rob. *) Described the items constraints properly for iep property in patch 2 as asked by Rob. *) Added Roger and Simon's RB tags.
Changes from v4 to v5: *) Added comments on why we are using readl / writel instead of regmap_read() / write() in icss_iep_gettime() / settime() APIs as asked by Roger. *) Added Conor's RB tag in patch 1 and 2.
Change from v3 to v4: *) Changed compatible in iep dt bindings. Now each SoC has their own compatible in the binding with "ti,am654-icss-iep" as a fallback as asked by Conor. *) Addressed Andew's comments and removed helper APIs icss_iep_readl() / writel(). Now the settime/gettime APIs directly use readl() / writel(). *) Moved selecting TI_ICSS_IEP in Kconfig from patch 3 to patch 4. *) Removed forward declaration of icss_iep_of_match in patch 3. *) Replaced use of of_device_get_match_data() to device_get_match_data() in patch 3. *) Removed of_match_ptr() from patch 3 as it is not needed.
Changes from v2 to v3: *) Addressed Roger's comment and moved IEP1 related changes in patch 5. *) Addressed Roger's comment and moved icss_iep.c / .h changes from patch 4 to patch 3. *) Added support for multiple timestamping in patch 4 as asked by Roger. *) Addressed Andrew's comment and added comment in case SPEED_10 in icssg_config_ipg() API. *) Kept compatible as "ti,am654-icss-iep" for all TI K3 SoCs
Changes from v1 to v2: *) Addressed Simon's comment to fix reverse xmas tree declaration. Some APIs in patch 3 and 4 were not following reverse xmas tree variable declaration. Fixed it in this version. *) Addressed Conor's comments and removed unsupported SoCs from compatible comment in patch 1. *) Addded patch 2 which was not part of v1. Patch 2, adds IEP node to dt bindings for ICSSG.

Merge branch 'icssg-driver'
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.
Changes from v7 to v8 : *) Rebased the series on 6.5-rc1. *) Fixed few formattings.
Changes from v6 to v7 : *) Added RB tag of Rob in patch 1 of this series. *) Addressed Simon's comment on patch 2 of the series. *) Rebased patchset on next-20230428 linux-next.
Changes from v5 to v6 : *) Added RB tag of Andrew Lunn in patch 2 of this series. *) Addressed Rob's comment on patch 1 of the series. *) Rebased patchset on next-20230421 linux-next.
Changes from v4 to v5 : *) Re-arranged properties section in ti,icssg-prueth.yaml file. *) Added requirement for minimum one ethernet port. *) Fixed some minor formatting errors as asked by Krzysztof. *) Dropped SGMII mode from enum mii_mode as SGMII mode is not currently supported by the driver. *) Added switch-case block to handle different phy modes by ICSSG driver.
Changes from v3 to v4 : *) Addressed Krzysztof's comments and fixed dt_binding_check errors in patch 1/2. *) Added interrupt-extended property in ethernet-ports properties section. *) Fixed comments in file icssg_switch_map.h according to the Linux coding style in patch 2/2. Added Documentation of structures in patch 2/2.
Changes from v2 to v3 : *) Addressed Rob and Krzysztof's comments on patch 1 of this series. Fixed indentation. Removed description and pinctrl section from ti,icssg-prueth.yaml file. *) Addressed Krzysztof, Paolo, Randy, Andrew and Christophe's comments on patch 2 of this seires. *) Fixed blanklines in Kconfig and Makefile. Changed structures to const as suggested by Krzysztof. *) Fixed while loop logic in emac_tx_complete_packets() API as suggested by Paolo. Previously in the loop's last iteration 'budget' was 0 and napi_consume_skb would wrongly assume the caller is not in NAPI context Now, budget won't be zero in last iteration of loop. *) Removed inline functions addr_to_da1() and addr_to_da0() as asked by Andrew. *) Added dev_err_probe() instead of dev_err() as suggested by Christophe. *) In ti,icssg-prueth.yaml file, in the patternProperties section of ethernet-ports, kept the port name as "port" instead of "ethernet-port" as all other drivers were using "port". Will change it if is compulsory to use "ethernet-port". ====================

net: ti: icssg-prueth: Add ICSSG Stats
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.

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.

net: ti: am65-cpsw-nuss: Add switchdev support
J721e, J7200 and AM64 have multi port switches which can work in multi mac mode and in switch mode. Add support for configuring this HW in switch mode using devlink and switchdev notifiers.
Support is similar to existing CPSW switchdev implementation of TI's 32 bit platform like AM33/AM43/AM57.
To enable switch mode: devlink dev param set platform/8000000.ethernet name switch_mode value true cmode runtime
All configuration is implemented via switchdev API and notifiers. Supported: - SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS - SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS - SWITCHDEV_ATTR_ID_PORT_STP_STATE - SWITCHDEV_OBJ_ID_PORT_VLAN - SWITCHDEV_OBJ_ID_PORT_MDB - SWITCHDEV_OBJ_ID_HOST_MDB
Hence AM65 CPSW switchdev driver supports: - FDB offloading - MDB offloading - VLAN filtering and offloading - STP
