Adjust the initialization sequence of KSZ88x3 switches to enable 802.1p priority control on Port 2 before configuring Port 1. This change ensures the apptrust functionality on Port 1 operates correctly, as it depends on the priority settings of Port 2. The prior initialization sequence incorrectly configured Port 1 first, which could lead to functional discrepancies.

2024-05-17bonding: fix oops during rmmodTony Battersby1-6/+7
"rmmod bonding" causes an oops ever since commit cc317ea3d927 ("bonding: remove redundant NULL check in debugfs function"). Here are the relevant functions being called: bonding_exit() bond_destroy_debugfs() debugfs_remove_recursive(bonding_debug_root); bonding_debug_root = NULL; <--------- SET TO NULL HERE bond_netlink_fini() rtnl_link_unregister() __rtnl_link_unregister() unregister_netdevice_many_notify() bond_uninit() bond_debug_unregister() (commit removed check for bonding_debug_root == NULL) debugfs_remove() simple_recursive_removal() down_write() -> OOPS However, reverting the bad commit does not solve the problem completely because the original code contains a race that could cause the same oops, although it was much less likely to be triggered unintentionally: CPU1 rmmod bonding bonding_exit() bond_destroy_debugfs() debugfs_remove_recursive(bonding_debug_root); CPU2 echo -bond0 > /sys/class/net/bonding_masters bond_uninit() bond_debug_unregister() if (!bonding_debug_root) CPU1 bonding_debug_root = NULL; So do NOT revert the bad commit (since the removed checks were racy anyway), and instead change the order of actions taken during module removal. The same oops can also happen if there is an error during module init, so apply the same fix there.

2024-05-15net: ks8851: Fix another TX stall caused by wrong ISR flag handlingRonald Wahl1-17/+1
Under some circumstances it may happen that the ks8851 Ethernet driver stops sending data. Currently the interrupt handler resets the interrupt status flags in the hardware after handling TX. With this approach we may lose interrupts in the time window between handling the TX interrupt and resetting the TX interrupt status bit. When all of the three following conditions are true then transmitting data stops: - TX queue is stopped to wait for room in the hardware TX buffer - no queued SKBs in the driver (txq) that wait for being written to hw - hardware TX buffer is empty and the last TX interrupt was lost This is because reenabling the TX queue happens when handling the TX interrupt status but if the TX status bit has already been cleared then this interrupt will never come. With this commit the interrupt status flags will be cleared before they are handled. That way we stop losing interrupts. The wrong handling of the ISR flags was there from the beginning but with commit 3dc5d4454545 ("net: ks8851: Fix TX stall caused by TX buffer overrun") the issue becomes apparent.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "Core & protocols: - Complete rework of garbage collection of AF_UNIX sockets. AF_UNIX is prone to forming reference count cycles due to fd passing functionality. New method based on Tarjan's Strongly Connected Components algorithm should be both faster and remove a lot of workarounds we accumulated over the years. - Add TCP fraglist GRO support, allowing chaining multiple TCP packets and forwarding them together. Useful for small switches / routers which lack basic checksum offload in some scenarios (e.g. PPPoE). - Support using SMP threads for handling packet backlog i.e. packet processing from software interfaces and old drivers which don't use NAPI. This helps move the processing out of the softirq jumble. - Continue work of converting from rtnl lock to RCU protection. Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files, MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs, neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link information available via rtnetlink. - Small optimizations from Eric to UDP wake up handling, memory accounting, RPS/RFS implementation, TCP packet sizing etc. - Allow direct page recycling in the bulk API used by XDP, for +2% PPS. - Support peek with an offset on TCP sockets. - Add MPTCP APIs for querying last time packets were received/sent/acked and whether MPTCP "upgrade" succeeded on a TCP socket. - Add intra-node communication shortcut to improve SMC performance. - Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver. - Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver. - Add reset reasons for tracing what caused a TCP reset to be sent. - Introduce direction attribute for xfrm (IPSec) states. State can be used either for input or output packet processing. Things we sprinkled into general kernel code: - Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS(). This required touch-ups and renaming of a few existing users. - Add Endian-dependent __counted_by_{le,be} annotations. - Make building selftests "quieter" by printing summaries like "CC object.o" rather than full commands with all the arguments. Netfilter: - Use GFP_KERNEL to clone elements, to deal better with OOM situations and avoid failures in the .commit step. BPF: - Add eBPF JIT for ARCv2 CPUs. - Support attaching kprobe BPF programs through kprobe_multi link in a session mode, meaning, a BPF program is attached to both function entry and return, the entry program can decide if the return program gets executed and the entry program can share u64 cookie value with return program. "Session mode" is a common use-case for tetragon and bpftrace. - Add the ability to specify and retrieve BPF cookie for raw tracepoint programs in order to ease migration from classic to raw tracepoints. - Add an internal-only BPF per-CPU instruction for resolving per-CPU memory addresses and implement support in x86, ARM64 and RISC-V JITs. This allows inlining functions which need to access per-CPU state. - Optimize x86 BPF JIT's emit_mov_imm64, and add support for various atomics in bpf_arena which can be JITed as a single x86 instruction. Support BPF arena on ARM64. - Add a new bpf_wq API for deferring events and refactor process-context bpf_timer code to keep common code where possible. - Harden the BPF verifier's and/or/xor value tracking. - Introduce crypto kfuncs to let BPF programs call kernel crypto APIs. - Support bpf_tail_call_static() helper for BPF programs with GCC 13. - Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF program to have code sections where preemption is disabled. Driver API: - Skip software TC processing completely if all installed rules are marked as HW-only, instead of checking the HW-only flag rule by rule. - Add support for configuring PoE (Power over Ethernet), similar to the already existing support for PoDL (Power over Data Line) config. - Initial bits of a queue control API, for now allowing a single queue to be reset without disturbing packet flow to other queues. - Common (ethtool) statistics for hardware timestamping. Tests and tooling: - Remove the need to create a config file to run the net forwarding tests so that a naive "make run_tests" can exercise them. - Define a method of writing tests which require an external endpoint to communicate with (to send/receive data towards the test machine). Add a few such tests. - Create a shared code library for writing Python tests. Expose the YAML Netlink library from tools/ to the tests for easy Netlink access. - Move netfilter tests under net/, extend them, separate performance tests from correctness tests, and iron out issues found by running them "on every commit". - Refactor BPF selftests to use common network helpers. - Further work filling in YAML definitions of Netlink messages for: nftables, team driver, bonding interfaces, vlan interfaces, VF info, TC u32 mark, TC police action. - Teach Python YAML Netlink to decode attribute policies. - Extend the definition of the "indexed array" construct in the specs to cover arrays of scalars rather than just nests. - Add hyperlinks between definitions in generated Netlink docs. Drivers: - Make sure unsupported flower control flags are rejected by drivers, and make more drivers report errors directly to the application rather than dmesg (large number of driver changes from Asbjørn Sloth Tønnesen). - Ethernet high-speed NICs: - Broadcom (bnxt): - support multiple RSS contexts and steering traffic to them - support XDP metadata - make page pool allocations more NUMA aware - Intel (100G, ice, idpf): - extract datapath code common among Intel drivers into a library - use fewer resources in switchdev by sharing queues with the PF - add PFCP filter support - add Ethernet filter support - use a spinlock instead of HW lock in PTP clock ops - support 5 layer Tx scheduler topology - nVidia/Mellanox: - 800G link modes and 100G SerDes speeds - per-queue IRQ coalescing configuration - Marvell Octeon: - support offloading TC packet mark action - Ethernet NICs consumer, embedded and virtual: - stop lying about skb->truesize in USB Ethernet drivers, it messes up TCP memory calculations - Google cloud vNIC: - support changing ring size via ethtool - support ring reset using the queue control API - VirtIO net: - expose flow hash from RSS to XDP - per-queue statistics - add selftests - Synopsys (stmmac): - support controllers which require an RX clock signal from the MII bus to perform their hardware initialization - TI: - icssg_prueth: support ICSSG-based Ethernet on AM65x SR1.0 devices - icssg_prueth: add SW TX / RX Coalescing based on hrtimers - cpsw: minimal XDP support - Renesas (ravb): - support describing the MDIO bus - Realtek (r8169): - add support for RTL8168M - Microchip Sparx5: - matchall and flower actions mirred and redirect - Ethernet switches: - nVidia/Mellanox: - improve events processing performance - Marvell: - add support for MV88E6250 family internal PHYs - Microchip: - add DCB and DSCP mapping support for KSZ switches - vsc73xx: convert to PHYLINK - Realtek: - rtl8226b/rtl8221b: add C45 instances and SerDes switching - Many driver changes related to PHYLIB and PHYLINK deprecated API cleanup - Ethernet PHYs: - Add a new driver for Airoha EN8811H 2.5 Gigabit PHY. - micrel: lan8814: add support for PPS out and external timestamp trigger - WiFi: - Disable Wireless Extensions (WEXT) in all Wi-Fi 7 devices drivers.

The blamed commit started to use the ptp workqueue to get the second part of the timestamp. And when the port was set down, then this workqueue is stopped. But if the config option NETWORK_PHY_TIMESTAMPING is not enabled, then the ptp_clock is not initialized so then it would crash when it would try to access the delayed work. So then basically by setting up and then down the port, it would crash. The fix consists in checking if the ptp_clock is initialized and only then cancel the delayed work.

2024-05-14net: prestera: Add flex arrays to some structsErick Archer1-46/+37
The "struct prestera_msg_vtcam_rule_add_req" uses a dynamically sized set of trailing elements. Specifically, it uses an array of structures of type "prestera_msg_acl_action actions_msg". The "struct prestera_msg_flood_domain_ports_set_req" also uses a dynamically sized set of trailing elements. Specifically, it uses an array of structures of type "prestera_msg_acl_action actions_msg". So, use the preferred way in the kernel declaring flexible arrays [1]. At the same time, prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). In this case, it is important to note that the attribute used is specifically __counted_by_le since the counters are of type __le32. The logic does not need to change since the counters for the flexible arrays are asigned before any access to the arrays. The order in which the structure prestera_msg_vtcam_rule_add_req and the structure prestera_msg_flood_domain_ports_set_req are defined must be changed to avoid incomplete type errors. Also, avoid the open-coded arithmetic in memory allocator functions [2] using the "struct_size" macro. Moreover, the new structure members also allow us to avoid the open- coded arithmetic on pointers. So, take advantage of this refactoring accordingly. This code was detected with the help of Coccinelle, and audited and modified manually.

2024-05-14net: fec: remove .ndo_poll_controller to avoid deadlocksWei Fang1-26/+0
There is a deadlock issue found in sungem driver, please refer to the commit ac0a230f719b ("eth: sungem: remove .ndo_poll_controller to avoid deadlocks"). The root cause of the issue is that netpoll is in atomic context and disable_irq() is called by .ndo_poll_controller interface of sungem driver, however, disable_irq() might sleep. After analyzing the implementation of fec_poll_controller(), the fec driver should have the same issue. Due to the fec driver uses NAPI for TX completions, the .ndo_poll_controller is unnecessary to be implemented in the fec driver, so fec_poll_controller() can be safely removed.

This patch adds to mlx5 drivers support for 8 ports HCAs. Starting with ConnectX-8 HCAs with 8 ports are possible. As most driver parts aren't affected by such configuration most driver code is unchanged. Specially the only affected areas are: - Lag - Multiport E-Switch - Single FDB E-Switch All of the above are already factored in generic way, and LAG and VF LAG are tested, so all that left is to change a #define and remove checks which are no longer needed. However, Multiport E-Switch is not tested yet, so it is left untouched. This patch will allow to create hardware LAG/VF LAG when all 8 ports are added to the same bond device. for example, In order to activate the hardware lag a user can execute the following: ip link add bond0 type bond ip link set bond0 type bond miimon 100 mode 2 ip link set eth2 master bond0 ip link set eth3 master bond0 ip link set eth4 master bond0 ip link set eth5 master bond0 ip link set eth6 master bond0 ip link set eth7 master bond0 ip link set eth8 master bond0 ip link set eth9 master bond0 Where eth2, eth3, eth4, eth5, eth6, eth7, eth8 and eth9 are the PFs of the same HCA.

This patch do not affect other KSZ8 related quirks. User will still be warned by setting not support configurations for the port 2.

2024-05-14net: dsa: microchip: dcb: rename IPV to IPMOleksij Rempel3-51/+51
IPV is added and used term in 802.1Qci PSFP and merged into 802.1Q (from 802.1Q-2018) for another functions. Even it does similar operation holding temporal priority value internally (as it is named), because KSZ datasheet doesn't use the term of IPV (Internal Priority Value) and avoiding any confusion later when PSFP is in the Linux world, it is better to rename IPV to IPM (Internal Priority Mapping). In addition, LAN937x documentation already use IPV for 802.1Qci PSFP related functionality.

2024-05-14net: usb: ax88179_178a: fix link status when link is set to down/upJose Ignacio Tornos Martinez1-11/+26
The idea was to keep only one reset at initialization stage in order to reduce the total delay, or the reset from usbnet_probe or the reset from usbnet_open. I have seen that restarting from usbnet_probe is necessary to avoid doing too complex things. But when the link is set to down/up (for example to configure a different mac address) the link is not correctly recovered unless a reset is commanded from usbnet_open. So, detect the initialization stage (first call) to not reset from usbnet_open after the reset from usbnet_probe and after this stage, always reset from usbnet_open too (when the link needs to be rechecked). Apply to all the possible devices, the behavior now is going to be the same. cc: stable@vger.kernel.org # 6.6+ Fixes: 56f78615bcb1 ("net: usb: ax88179_178a: avoid writing the mac address before first reading") Reported-by: Isaac Ganoung <inventor500@vivaldi.net> Reported-by: Yongqin Liu <yongqin.liu@linaro.org> Signed-off-by: Jose Ignacio Tornos Martinez <jtornosm@redhat.com> Reviewed-by: Simon Horman <horms@kernel.org> Link: https://lore.kernel.org/r/20240510090846.328201-1-jtornosm@redhat.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

As this is a non-critical error in our case, adding a debug level print for indication.
