git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "The zero-copy changes are relatively significant, but regression risk should be contained. The feature needs to be used to cause trouble. Also it feels like we got an order of magnitude more semi-automated "refactoring" chaff than usual, I wonder if it's just us. Core & protocols: - Support Device Memory TCP, ability to zero-copy receive TCP payloads to a DMABUF region of memory while packet headers land separately in normal kernel buffers, and TCP processes then as usual. - The ability to read the PTP PHC (Physical Hardware Clock) alongside MONOTONIC_RAW timestamps with PTP_SYS_OFFSET_EXTENDED. Previously only CLOCK_REALTIME was supported. - Allow matching on all bits of IP DSCP for routing decisions. Previously we only supported on matching TOS bits in IPv4 which is a narrower interpretation of the same header field. - Increase the range of weights used for multi-path routing from 8 bits to 16 bits. - Add support for IPv6 PIO p flag in the Prefix Information Option per draft-ietf-6man-pio-pflag. - IPv6 IOAM6 support for new tunsrc encap mode for better performance. - Detect destinations which blackhole MPTCP traffic and avoid initiating MPTCP connections to them for a certain period of time, 1h by default. - Improve IPsec control path performance by removing the inexact policies list. - AF_VSOCK: add support for SIOCOUTQ ioctl. - Add enum for reasons TCP reset was sent for easier tracing. - Add SMC ringbufs usage statistics. Drivers: - Handle netconsole setup failures more gracefully, don't fail loading, retain the specified target as disabled. - Extend bonding's IPsec offload pass thru capabilities (ESN, stats). Filtering: - Add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_*sockopt() to address the case when long-lived sockets miss a chance to set additional callbacks if a sockops program was not attached early in their lifetime. - Support using BPF skb helpers in tracepoints. - Conntrack Netlink: support CTA_FILTER for flush. - Improve SCTP support in nfnetlink_queue. - Improve performance of large nftables flush transactions. Things we sprinkled into general kernel code: - selftests: support setting an "interpreter" for script files; make it easy to run as separate cases tests where one "interpreter" is fed various test descriptions (in our case packet sequences). Driver API: - Extend core and ethtool APIs to support many PHYs connected to a single interface (PHY topologies). - Extend cable diagnostics to specify whether Time Domain Reflectometry (TDR) or Active Link Cable Diagnostic (ALCD) was used. - Add library for implementing MAC-PHY Ethernet drivers for SPI devices compatible with Open Alliance 10BASE-T1x MAC-PHY Serial Interface (TC6) standard. - Add helpers to the PHY framework, for PHYs following the Open Alliance standards: - 1000BaseT1 link settings - cable test and diagnostics - Support listing / dumping all allocated RSS contexts. - Add configuration for frequency Embedded SYNC in DPLL, which magically embeds sync pulses into Ethernet signaling.

2024-09-15cifs: Recognize SFU socket typePali Rohár1-1/+5
SFU since its (first) version 3.0 supports AF_LOCAL sockets and stores them on filesytem as system file with one zero byte. Add support for detecting this SFU socket type into cifs_sfu_type() function. With this change cifs_sfu_type() would correctly detect all special file types created by SFU: fifo, socket, symlink, block and char.

2024-09-15cifs: Put explicit zero byte into SFU block/char typesPali Rohár2-4/+4
SFU types IntxCHR and IntxBLK are 8 bytes with zero as last byte. Make it explicit in memcpy and memset calls, so the zero byte is visible in the code (and not hidden as string trailing nul byte). It is important for reader to show the last byte for block and char types because it differs from the last byte of symlink type (which has it 0x01). Also it is important to show that the type is not nul-term string, but rather 8 bytes (with some printable bytes).

2024-09-15cifs: Add support for reading SFU symlink locationPali Rohár1-0/+29
Currently when sfu mount option is specified then CIFS can recognize SFU symlink, but is not able to read symlink target location. readlink() syscall just returns that operation is not supported. Implement this missing functionality in cifs_sfu_type() function. Read target location of SFU-style symlink, parse it and fill into fattr's cf_symlink_target member. SFU-style symlink is file which has system attribute set and file content is buffer "IntxLNK\1" (8th byte is 0x01) followed by the target location encoded in little endian UCS-2/UTF-16. This format was introduced in Interix 3.0 subsystem, as part of the Microsoft SFU 3.0 and is used also by all later versions. Previous versions had no symlink support.

* Raw NAND changes The use of for_each_child_of_node_scoped() has been spread into the subsystem drivers. Aside from that, a couple of exit path have been fixed (mtk, denali), the TI GPMC bindings have been enhanced to comply with up-to-date partition descriptions and as always there is a load of small and misc fixes. * SPI-NAND changes The most impacting series this cycle is bringing support for continuous reads in the SPI-NAND subsystem. This is a feature already merged in the raw NAND subsystem which allows optimizing the internal fetch times in the chip while reading sequential pages within an eraseblock. For now only Macronix NANDs benefit from this feature. While we are talking about Macronix, some of their chip need an explicit action for selecting a different plane, and support for it has also been brought. The bitflip threshold has also been set to the same arbitrary level as in the raw NAND subsystem to optimize wear leveling decisions, and finally support for a new Winbond chip has been added.

SPI NOR changes for 6.12 Notable changes: - Add Write Protect support for N25Q064A. - New flash support for Zetta ZD25Q128C and Spansion S28HS256T. - Fix a NULL dereference in probe path for flashes without a name. The probe path tries to access the name without checking its existence first. S28HS256T is the first flash to define its entry without a name, uncovering this issue.

Pull kvm fix from Paolo Bonzini: "Do not always honor guest PAT on CPUs that support self-snoop. This triggers an issue in the bochsdrm driver, which used ioremap() instead of ioremap_wc() to map the video RAM. The revert lets video RAM use the WB memory type instead of the slower UC memory type" * tag 'for-linus-6.11' of git://git.kernel.org/pub/scm/virt/kvm/kvm: Revert "KVM: VMX: Always honor guest PAT on CPUs that support self-snoop"
2024-09-15Revert "KVM: VMX: Always honor guest PAT on CPUs that support self-snoop"Paolo Bonzini2-11/+7
This reverts commit 377b2f359d1f71c75f8cc352b5c81f2210312d83. This caused a regression with the bochsdrm driver, which used ioremap() instead of ioremap_wc() to map the video RAM. After the commit, the WB memory type is used without the IGNORE_PAT, resulting in the slower UC memory type. In fact, UC is slow enough to basically cause guests to not boot... but only on new processors such as Sapphire Rapids and Cascade Lake. Coffee Lake for example works properly, though that might also be an effect of being on a larger, more NUMA system. The driver has been fixed but that does not help older guests. Until we figure out whether Cascade Lake and newer processors are working as intended, revert the commit. Long term we might add a quirk, but the details depend on whether the processors are working as intended: for example if they are, the quirk might reference bochs-compatible devices, e.g. in the name and documentation, so that userspace can disable the quirk by default and only leave it enabled if such a device is being exposed to the guest. If instead this is actually a bug in CLX+, then the actions we need to take are different and depend on the actual cause of the bug. Signed-off-by: Paolo Bonzini <[email protected]>

To support HSR offload to hardware, ICSSG HSR firmware is used. This series introduces, 1. HSR frame offload support for ICSSG driver. 2. HSR Tx Packet duplication offload 3. HSR Tx Tag and Rx Tag offload 4. Multicast filtering support in HSR offload mode. 5. Dependencies related to IEP.

Add support to offload HSR Tx Tag Insertion and Rx Tag Removal and duplicate discard. hsr tag insertion offload and hsr dup offload are tightly coupled in firmware implementation. Both these features need to be enabled / disabled together. Duplicate discard is done as part of RX tag removal and it is done by the firmware.
