2025-05-27spi: spi-pci1xxxx: Fix Probe failure with Dual SPI instance with INTx interruptsThangaraj Samynathan
Fixes a probe failure that occurs when dual SPI controllers are enabled and INTx interrupts are used. Reduces the minimum required number of interrupt vectors to 1 and registers a shared ISR when the allocated vectors are fewer than the number of controllers. This change ensures that the probe succeeds even with limited vectors, restoring INTx functionality when multiple SPI controllers are present.

2025-05-27net: phy: add driver for MaxLinear MxL86110 PHYStefano Radaelli
Add support for the MaxLinear MxL86110 Gigabit Ethernet PHY, a low-power, cost-optimized transceiver supporting 10/100/1000 Mbps over twisted-pair copper, compliant with IEEE 802.3. The driver implements basic features such as: - Device initialization - RGMII interface timing configuration - Wake-on-LAN support - LED initialization and control via /sys/class/leds This driver has been tested on multiple Variscite boards, including: - VAR-SOM-MX93 (i.MX93) - VAR-SOM-MX8M-PLUS (i.MX8MP) Example boot log showing driver probe: [ 7.692101] imx-dwmac 428a0000.ethernet eth0: PHY [stmmac-0:00] driver [MXL86110 Gigabit Ethernet] (irq=POLL) Signed-off-by: Stefano Radaelli <stefano.radaelli21@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Link: https://patch.msgid.link/20250521212821.593057-1-stefano.radaelli21@gmail.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>
2025-05-27wireguard: allowedips: add WGALLOWEDIP_F_REMOVE_ME flagJordan Rife
The current netlink API for WireGuard does not directly support removal of allowed ips from a peer. A user can remove an allowed ip from a peer in one of two ways: 1. By using the WGPEER_F_REPLACE_ALLOWEDIPS flag and providing a new list of allowed ips which omits the allowed ip that is to be removed. 2. By reassigning an allowed ip to a "dummy" peer then removing that peer with WGPEER_F_REMOVE_ME. With the first approach, the driver completely rebuilds the allowed ip list for a peer. If my current configuration is such that a peer has allowed ips 192.168.0.2 and 192.168.0.3 and I want to remove 192.168.0.2 the actual transition looks like this. [192.168.0.2, 192.168.0.3] <-- Initial state [] <-- Step 1: Allowed ips removed for peer [192.168.0.3] <-- Step 2: Allowed ips added back for peer This is true even if the allowed ip list is small and the update does not need to be batched into multiple WG_CMD_SET_DEVICE requests, as the removal and subsequent addition of ips is non-atomic within a single request. Consequently, wg_allowedips_lookup_dst and wg_allowedips_lookup_src may return NULL while reconfiguring a peer even for packets bound for ips a user did not intend to remove leading to unintended interruptions in connectivity. This presents in userspace as failed calls to sendto and sendmsg for UDP sockets. In my case, I ran netperf while repeatedly reconfiguring the allowed ips for a peer with wg. /usr/local/bin/netperf -H 10.102.73.72 -l 10m -t UDP_STREAM -- -R 1 -m 1024 send_data: data send error: No route to host (errno 113) netperf: send_omni: send_data failed: No route to host While this may not be of particular concern for environments where peers and allowed ips are mostly static, systems like Cilium manage peers and allowed ips in a dynamic environment where peers (i.e. Kubernetes nodes) and allowed ips (i.e. pods running on those nodes) can frequently change making WGPEER_F_REPLACE_ALLOWEDIPS problematic. The second approach avoids any possible connectivity interruptions but is hacky and less direct, requiring the creation of a temporary peer just to dispose of an allowed ip. Introduce a new flag called WGALLOWEDIP_F_REMOVE_ME which in the same way that WGPEER_F_REMOVE_ME allows a user to remove a single peer from a WireGuard device's configuration allows a user to remove an ip from a peer's set of allowed ips. This enables incremental updates to a device's configuration without any connectivity blips or messy workarounds. A corresponding patch for wg extends the existing `wg set` interface to leverage this feature. $ wg set wg0 peer <PUBKEY> allowed-ips +192.168.88.0/24,-192.168.0.1/32 When '+' or '-' is prepended to any ip in the list, wg clears WGPEER_F_REPLACE_ALLOWEDIPS and sets the WGALLOWEDIP_F_REMOVE_ME flag on any ip prefixed with '-'.

Add cmdq_gctl_value_toggle() to configure GCE_CTRL_BY_SW and GCE_DDR_EN together in the same GCE_GCTL_VALUE register. For the SoCs whose GCE is located in MMINFRA and uses MMINFRA_AO power, this allows it to be written without enabling the clocks. Otherwise, all GCE registers should be written after the GCE clocks are enabled. Move this function into cmdq_runtime_resume() and cmdq_runtime_suspend() to ensure it is called when the GCE clock is enabled.

2025-05-26mailbox: imx: Fix TXDB_V2 sendingPeng Fan
i.MX95 features several processing domains, Cortex-M7, Cortex-A55 secure, Cortex-A55 non-secure. Each domain could communicate with SCMI firmware with a dedicated MU. But the current NXP SCMI firmware is not a RTOS, all processing logic codes are in interrupt context. So if high priority Cortex-M7 is communicating with SCMI firmware and requires a bit more time to handle the SCMI call, Linux MU TXDB_V2 will be timeout with high possiblity in 1000us(the current value in imx-mailbox.c). Per NXP SCMI firmware design, if timeout, there is no recover logic, so SCMI agents should never timeout and always wait until the check condition met. Based on the upper reason, enlarge the timeout value to 10ms which is less chance to timeout, and retry if timeout really happends.

2025-05-26net: lan966x: Fix 1-step timestamping over ipv4 or ipv6Horatiu Vultur
When enabling 1-step timestamping for ptp frames that are over udpv4 or udpv6 then the inserted timestamp is added at the wrong offset in the frame, meaning that will modify the frame at the wrong place, so the frame will be malformed. To fix this, the HW needs to know which kind of frame it is to know where to insert the timestamp. For that there is a field in the IFH that says the PDU_TYPE, which can be NONE which is the default value, IPV4 or IPV6. Therefore make sure to set the PDU_TYPE so the HW knows where to insert the timestamp. Like I mention before the issue is not seen with L2 frames because by default the PDU_TYPE has a value of 0, which represents the L2 frames.

2025-05-26RDMA/cma: Fix hang when cma_netevent_callback fails to queue_workJack Morgenstein
The cited commit fixed a crash when cma_netevent_callback was called for a cma_id while work on that id from a previous call had not yet started. The work item was re-initialized in the second call, which corrupted the work item currently in the work queue. However, it left a problem when queue_work fails (because the item is still pending in the work queue from a previous call). In this case, cma_id_put (which is called in the work handler) is therefore not called. This results in a userspace process hang (zombie process). Fix this by calling cma_id_put() if queue_work fails.
