git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "Not much excitement - a handful of large patchsets (devmem among them) did not make it in time. Core & protocols: - Use local_lock in addition to local_bh_disable() to protect per-CPU resources in networking, a step closer for local_bh_disable() not to act as a big lock on PREEMPT_RT - Use flex array for netdevice priv area, ensure its cache alignment - Add a sysctl knob to allow user to specify a default rto_min at socket init time. Bit of a big hammer but multiple companies were independently carrying such patch downstream so clearly it's useful - Support scheduling transmission of packets based on CLOCK_TAI - Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned off using cpusets - Support multiple L2TPv3 UDP tunnels using the same 5-tuple address - Allow configuration of multipath hash seed, to both allow synchronizing hashing of two routers, and preventing partial accidental sync - Improve TCP compliance with RFC 9293 for simultaneous connect() - Support sending NAT keepalives in IPsec ESP in UDP states. Userspace IKE daemon had to do this before, but the kernel can better keep track of it - Support sending supervision HSR frames with MAC addresses stored in ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled - Introduce IPPROTO_SMC for selecting SMC when socket is created - Allow UDP GSO transmit from devices with no checksum offload - openvswitch: add packet sampling via psample, separating the sampled traffic from "upcall" packets sent to user space for forwarding - nf_tables: shrink memory consumption for transaction objects Things we sprinkled into general kernel code: - Power Sequencing subsystem (used by Qualcomm Bluetooth driver for QCA6390) [ Already merged separately - Linus ] - Add IRQ information in sysfs for auxiliary bus - Introduce guard definition for local_lock - Add aligned flavor of __cacheline_group_{begin, end}() markings for grouping fields in structures BPF: - Notify user space (via epoll) when a struct_ops object is getting detached/unregistered - Add new kfuncs for a generic, open-coded bits iterator - Enable BPF programs to declare arrays of kptr, bpf_rb_root, and bpf_list_head - Support resilient split BTF which cuts down on duplication and makes BTF as compact as possible WRT BTF from modules - Add support for dumping kfunc prototypes from BTF which enables both detecting as well as dumping compilable prototypes for kfuncs - riscv64 BPF JIT improvements in particular to add 12-argument support for BPF trampolines and to utilize bpf_prog_pack for the latter - Add the capability to offload the netfilter flowtable in XDP layer through kfuncs Driver API: - Allow users to configure IRQ tresholds between which automatic IRQ moderation can choose - Expand Power Sourcing (PoE) status with power, class and failure reason. Support setting power limits - Track additional RSS contexts in the core, make sure configuration changes don't break them - Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated ESP data paths -

2024-07-05net: stmmac: Create DW XPCS device with particular addressSerge Semin
Currently the only STMMAC platform driver using the DW XPCS code is the Intel mGBE device driver. (It can be determined by finding all the drivers having the stmmac_mdio_bus_data::has_xpcs flag set.) At the same time the low-level platform driver masks out the DW XPCS MDIO-address from being auto-detected as PHY by the MDIO subsystem core. Seeing the PCS MDIO ID is known the procedure of the DW XPCS device creation can be simplified by dropping the loop over all the MDIO IDs. From now the DW XPCS device descriptor will be created for the MDIO-bus address pre-defined by the platform drivers via the stmmac_mdio_bus_data::pcs_mask field. Note besides this shall speed up a bit the Intel mGBE probing. Signed-off-by: Serge Semin <fancer.lancer@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Currently, intel_speed_mode_2500() will fix-up xpcs_an_inband to 1 if the underlying controller has a max speed of 1000Mbps.

In stmmac_phy_setup(), ovr_an_inband is set based on the value of xpcs_an_inband. Which in turn will return an error in phylink_parse_mode() where MLO_AN_FIXED and ovr_an_inband are both set.

2023-03-19net: stmmac: Fix for mismatched host/device DMA address widthJochen Henneberg
Currently DMA address width is either read from a RO device register or force set from the platform data. This breaks DMA when the host DMA address width is <=32it but the device is >32bit. Right now the driver may decide to use a 2nd DMA descriptor for another buffer (happens in case of TSO xmit) assuming that 32bit addressing is used due to platform configuration but the device will still use both descriptor addresses as one address. This can be observed with the Intel EHL platform driver that sets 32bit for addr64 but the MAC reports 40bit. The TX queue gets stuck in case of TCP with iptables NAT configuration on TSO packets. The logic should be like this: Whatever we do on the host side (memory allocation GFP flags) should happen with the host DMA width, whenever we decide how to set addresses on the device registers we must use the device DMA address width. This patch renames the platform address width field from addr64 (term used in device datasheet) to host_addr and uses this value exclusively for host side operations while all chip operations consider the device DMA width as read from the device register.

2022-05-01net: stmmac: disable Split Header (SPH) for Intel platformsTan Tee Min
Based on DesignWare Ethernet QoS datasheet, we are seeing the limitation of Split Header (SPH) feature is not supported for Ipv4 fragmented packet. This SPH limitation will cause ping failure when the packets size exceed the MTU size. For example, the issue happens once the basic ping packet size is larger than the configured MTU size and the data is lost inside the fragmented packet, replaced by zeros/corrupted values, and leads to ping fail. So, disable the Split Header for Intel platforms. v2: Add fixes tag in commit message.

2022-02-07net: stmmac: optimize locking around PTP clock readsYannick Vignon
Reading the PTP clock is a simple operation requiring only 3 register reads. Under a PREEMPT_RT kernel, protecting those reads by a spin_lock is counter-productive: if the 2nd task preempting the 1st has a higher prio but needs to read time as well, it will require 2 context switches, which will pretty much always be more costly than just disabling preemption for the duration of the reads. Moreover, with the code logic recently added to get_systime(), disabling preemption is not even required anymore: reads and writes just need to be protected from each other, to prevent a clock read while the clock is being updated. Improve the above situation by replacing the PTP spinlock by a rwlock, and using read_lock for PTP clock reads so simultaneous reads do not block each other.

2021-06-08net: stmmac: enable Intel mGbE 2.5Gbps link speedVoon Weifeng
The Intel mGbE supports 2.5Gbps link speed by increasing the clock rate by 2.5 times of the original rate. In this mode, the serdes/PHY operates at a serial baud rate of 3.125 Gbps and the PCS data path and GMII interface of the MAC operate at 312.5 MHz instead of 125 MHz. For Intel mGbE, the overclocking of 2.5 times clock rate to support 2.5G is only able to be configured in the BIOS during boot time. Kernel driver has no access to modify the clock rate for 1Gbps/2.5G mode. The way to determined the current 1G/2.5G mode is by reading a dedicated adhoc register through mdio bus. In short, after the system boot up, it is either in 1G mode or 2.5G mode which not able to be changed on the fly. Compared to 1G mode, the 2.5G mode selects the 2500BASEX as PHY interface and disables the xpcs_an_inband. This is to cater for some PHYs that only supports 2500BASEX PHY interface with no autonegotiation. v2: remove MAC supported link speed masking v3: Restructure to introduce intel_speed_mode_2500() to read serdes registers for max speed supported and select the appropritate configuration. Use max_speed to determine the supported link speed mask.
