2025-02-10eth: fbnic: support n-tuple filtersAlexander Duyck
Add ethtool -n / -N support. Support only "un-ordered" rule sets (RX_CLS_LOC_ANY), just for simplicity of the code. It's unclear anyone actually cares about the rule ordering.

2025-02-10eth: fbnic: add IP TCAM programmingAlexander Duyck
IPv6 addresses are huge so the device has 4 TCAMs used for narrowing them down to a smaller key before the main match / action engine. Add the tables in which we'll keep the IP addresses used by ethtool n-tuple rules. Add the code for programming them into the device, and code for allocating and freeing entries. A bit of copy / paste here as we need to support IPv4 and IPv6 in the same tables, and there is four of them. But it makes the code easier to match up with the device.

2025-02-10netconsole: add support for sysdata and CPU populationBreno Leitao
Add infrastructure to automatically append kernel-generated data (sysdata) to netconsole messages. As the first use case, implement CPU number population, which adds the CPU that sent the message. This change introduces three distinct data types: - extradata: The complete set of appended data (sysdata + userdata) - userdata: User-provided key-value pairs from userspace - sysdata: Kernel-populated data (e.g. cpu=XX) The implementation adds a new configfs attribute 'cpu_nr' to control CPU number population per target. When enabled, each message is tagged with its originating CPU. The sysdata is dynamically updated at message time and appended after any existing userdata. The CPU number is formatted as "cpu=XX" and is added to the extradata buffer, respecting the existing size limits.

2025-02-10netconsole: Rename userdata to extradataBreno Leitao
Rename "userdata" to "extradata" since this structure will hold both user and system data in future patches. Keep "userdata" term only for data that comes from userspace (configfs), while "extradata" encompasses both userdata and future kerneldata. These are the rules of the design 1. extradata_complete will hold userdata and sysdata (coming) 2. sysdata will come after userdata_length 3. extradata_complete[userdata_length] string will be replaced at every message 5. userdata is replaced when configfs changes (update_userdata()) 6. sysdata is replaced at every message Example: extradata_complete = "userkey=uservalue cpu=42" userdata_length = 17 sysdata_length = 7 (space (" ") is part of sysdata) Since sysdata is still not available, you will see the following in the send functions: extradata_len = nt->userdata_length; The upcoming patches will, which will add support for sysdata, will change it to: extradata_len = nt->userdata_length + sysdata_len; Signed-off-by: Breno Leitao <leitao@debian.org> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: David S.

2025-02-10iommu: Fix potential memory leak in iopf_queue_remove_device()Lu Baolu
The iopf_queue_remove_device() helper removes a device from the per-iommu iopf queue when PRI is disabled on the device. It responds to all outstanding iopf's with an IOMMU_PAGE_RESP_INVALID code and detaches the device from the queue. However, it fails to release the group structure that represents a group of iopf's awaiting for a response after responding to the hardware. This can cause a memory leak if iopf_queue_remove_device() is called with pending iopf's. Fix it by calling iopf_free_group() after the iopf group is responded.

2025-02-10ata: libahci_platform: Do not set mask_port_map when not neededDamien Le Moal
Commit 8c87215dd3a2 ("ata: libahci_platform: support non-consecutive port numbers") modified ahci_platform_get_resources() to allow identifying the ports of a controller that are defined as child nodes of the controller node in order to support non-consecutive port numbers (as defined by the platform device tree). However, this commit also erroneously sets bit 0 of hpriv->mask_port_map when the platform devices tree does not define port child nodes, to match the fact that the temporary default number of ports used in that case is 1 (which is also consistent with the fact that only index 0 of hpriv->phys[] is initialized with the call to ahci_platform_get_phy(). But doing so causes ahci_platform_init_host() to initialize and probe only the first port, even if this function determines that the controller has in fact multiple ports using the capability register of the controller (through a call to ahci_nr_ports()). This can be seen with the ahci_mvebu driver (Armada 385 SoC) with the second port declared as "dummy": ahci-mvebu f10a8000.sata: masking port_map 0x3 -> 0x1 ahci-mvebu f10a8000.sata: AHCI vers 0001.0000, 32 command slots, 6 Gbps, platform mode ahci-mvebu f10a8000.sata: 1/2 ports implemented (port mask 0x1) ahci-mvebu f10a8000.sata: flags: 64bit ncq sntf led only pmp fbs pio slum part sxs scsi host0: ahci-mvebu scsi host1: ahci-mvebu ata1: SATA max UDMA/133 mmio [mem 0xf10a8000-0xf10a9fff] port 0x100 irq 40 lpm-pol 0 ata2: DUMMY Fix this issue by removing setting bit 0 of hpriv->mask_port_map when the platform device tree does not define port child nodes.

2025-02-10wifi: rtw89: coex: To avoid TWS serials A2DP lag, adjust slot arrangementChing-Te Ku
The TWS(True wireless stereo) serials Bluetooth audio device need to keep packet traffic not only with DUT, it also need to synchronize packet with its assistant earbud. And all the BR/EDR Bluetooth device need to do page scan to keep re-connect event sensitively between different DUT. These behavior will make TWS Bluetooth device cost more time slot to keep the good audio performance. This patch decrease half of Wi-Fi slot(from 40ms to 20ms) in a single cycle. Make the slot more flexible to prevent audio lag. The single cycle will be shorter, then it will bring some slot protection cost make Wi-Fi throughput decrease about 5%.

2025-02-10wifi: rtw89: call power_on ahead before selecting firmwarePing-Ke Shih
Driver selects firmware by hardware version, which normally can be read from registers before selecting firmware. However, certain chips such as RTL8851B, it needs to read hardware version from efuse while doing power_on, but do power_on after selecting firmware in current flow. To resolve this flow problem, move power_on out from rtw89_mac_partial_init(), and call rtw89_mac_pwr_on() separately at proper places to have expected flow.

2025-02-09PM: sleep: core: Restrict power.set_active propagationRafael J. Wysocki
Commit 3775fc538f53 ("PM: sleep: core: Synchronize runtime PM status of parents and children") exposed an issue related to simple_pm_bus_pm_ops that uses pm_runtime_force_suspend() and pm_runtime_force_resume() as bus type PM callbacks for the noirq phases of system-wide suspend and resume. The problem is that pm_runtime_force_suspend() does not distinguish runtime-suspended devices from devices for which runtime PM has never been enabled, so if it sees a device with runtime PM status set to RPM_ACTIVE, it will assume that runtime PM is enabled for that device and so it will attempt to suspend it with the help of its runtime PM callbacks which may not be ready for that. As it turns out, this causes simple_pm_bus_runtime_suspend() to crash due to a NULL pointer dereference. Another problem related to the above commit and simple_pm_bus_pm_ops is that setting runtime PM status of a device handled by the latter to RPM_ACTIVE will actually prevent it from being resumed because pm_runtime_force_resume() only resumes devices with runtime PM status set to RPM_SUSPENDED. To mitigate these issues, do not allow power.set_active to propagate beyond the parent of the device with DPM_FLAG_SMART_SUSPEND set that will need to be resumed, which should be a sufficient stop-gap for the time being, but they will need to be properly addressed in the future because in general during system-wide resume it is necessary to resume all devices in a dependency chain in which at least one device is going to be resumed.

2025-02-09RDMA/hns: Fix mbox timing out by adding retry mechanismJunxian Huang
If a QP is modified to error state and a flush CQE process is triggered, the subsequent QP destruction mbox can still be successfully posted but will be blocked in HW until the flush CQE process finishes. This causes further mbox posting timeouts in driver. The blocking time is related to QP depth. Considering an extreme case where SQ depth and RQ depth are both 32K, the blocking time can reach about 135ms. This patch adds a retry mechanism for mbox posting. For each try, FW waits 15ms for HW to complete the previous mbox, otherwise return a timeout error code to driver. Counting other time consumption in FW, set 8 tries for mbox posting and a 5ms time gap before each retry to increase to a sufficient timeout limit.
