2024-06-03wifi: ath12k: add hw_link_id in ath12k_pdevKarthikeyan Periyasamy
Currently, hw_link_id is sent in WMI service ready event but it is not parsed anywhere. But, in future, for multi-link operation, this parameter would be needed by many WMI commands such as WMI beacon template (WMI_BCN_TMPL_CMDID), WMI vdev start for Multi-link virtual AP interfaces (WMI_VDEV_START_REQUEST_CMDID), WMI peer assoc command (WMI_PEER_ASSOC_CMDID) for Multi-link peer and so on. Hence, add changes to parse and store the hw_link_id received in WMI service ready event in ath12k_pdev structure.

2024-06-03wifi: ath12k: add panic handlerBaochen Qiang
Currently for ath12k PCI devices, firmware could be running in one of several execution environments, e.g., PBL, SBL and mission mode etc. Among which PBL is the only stage where PCIe link negotiation could happen. So normally firmware runs in PBL in order to be enumerated during system reboot. However it might not work in kernel crash scenario: ath12k target is not found after warm reboot from kernel crash. This is because when kernel crashes, ath12k host does nothing to firmware. And during warm reboot, WLAN power is sustained. So firmware is likely to keep running in mission mode throughout the bootup process. As a result PCIe link is not established and thus target not enumerated. So add a handler in panic notification list for ath12k. When kernel crashes, this handler gets called and tries to reset target to PBL state. Then PCIe link negotiation could happen and target gets enumerated. This change applies to all PCI devices including WCN7850 and QCN9274.

2024-06-03net: dsa: ocelot: common probing codeVladimir Oltean
Russell King suggested that felix_vsc9959, seville_vsc9953 and ocelot_ext have a large portion of duplicated init code, which could be made common [1]. [1]: https://lore.kernel.org/all/Zh1GvcOTXqb7CpQt@shell.armlinux.org.uk/ Here, we take the following common steps: - "felix" and "ds" structure allocation - "felix", "ocelot" and "ds" basic structure initialization - dsa_register_switch() call and we make a common function out of them. For every driver except felix_vsc9959, this is also the entire probing procedure. For felix_vsc9959, we also need to do some PCI-specific stuff, which can easily be reordered to be done before, and unwound on failure. We also have to convert the bus-specific platform_set_drvdata() and pci_set_drvdata() calls into dev_set_drvdata(). But this should have no impact on the behavior.

2024-06-03net: dsa: ocelot: use ds->num_tx_queues = OCELOT_NUM_TC for all modelsVladimir Oltean
Russell King points out that seville_vsc9953 populates felix->info->num_tx_queues = 8, but this doesn't make it all the way into ds->num_tx_queues (which is how the user interface netdev queues get allocated) [1]. [1]: https://lore.kernel.org/all/20240415160150.yejcazpjqvn7vhxu@skbuf/ When num_tx_queues=0 for seville, this is implicitly converted to 1 by dsa_user_create(), and this is good enough for basic operation for a switch port. The tc qdisc offload layer works with netdev TX queues, so for QoS offload we need to pretend we have multiple TX queues. The VSC9953, like ocelot_ext, doesn't export QoS offload, so it doesn't really matter. But we can definitely set num_tx_queues=8 for all switches. The felix->info->num_tx_queues construct itself seems unnecessary. It was introduced by commit de143c0e274b ("net: dsa: felix: Configure Time-Aware Scheduler via taprio offload") at a time when vsc9959 (LS1028A) was the only switch supported by the driver. 8 traffic classes, and 1 queue per traffic class, is a common architectural feature of all switches in the family. So they could all just set OCELOT_NUM_TC and be fine.

2024-06-03net: dsa: ocelot: move devm_request_threaded_irq() to felix_setup()Vladimir Oltean
The current placement of devm_request_threaded_irq() is inconvenient. It is between the allocation of the "felix" structure and dsa_register_switch(), both of which we'd like to refactor into a function that's common for all switches. But the IRQ is specific to felix_vsc9959. A closer inspection of the felix_irq_handler() code suggests that it does things that depend on the data structures having been fully initialized. For example, ocelot_get_txtstamp() takes &port->tx_skbs.lock, which has only been initialized in ocelot_init_port() which has not run yet. It is not one of those IRQF_SHARED IRQs, so CONFIG_DEBUG_SHIRQ_FIXME shouldn't apply here, and thus, it doesn't really matter, because in practice, the IRQ will not be triggered so early. Nonetheless, it is a good practice for the driver to be prepared for it to fire as soon as it is requested. Create a new felix->info method for running custom code for vsc9959 from within felix_setup(), and move the request_irq() call there. The ocelot_ext should have an IRQ as well, so this should be a step in the right direction for that model (VSC7512) as well. Some minor changes are made while moving the code. Casts from void * aren't necessary, so drop them, and rename felix_irq_handler() to the more specific vsc9959_irq_handler().

CONFIG_ARCH_NO_SG_CHAIN is defined SG_MAX_SINGLE_ALLOC is used to limit maximum number of entries that will be allocated in one piece of scatterlist. When the entries of scatterlist exceeds SG_MAX_SINGLE_ALLOC, sg chain will be used. From commit 7c703e54cc71 ("arch: switch the default on ARCH_HAS_SG_CHAIN"), we can know that the macro CONFIG_ARCH_NO_SG_CHAIN is used to identify whether sg chain is supported. So, SMC-R's rmb buffer should be limited by SG_MAX_SINGLE_ALLOC only when the macro CONFIG_ARCH_NO_SG_CHAIN is defined.

2024-06-01af_unix: Remove dead code in unix_stream_read_generic().Kuniyuki Iwashima
When splice() support was added in commit 2b514574f7e8 ("net: af_unix: implement splice for stream af_unix sockets"), we had to release unix_sk(sk)->readlock (current iolock) before calling splice_to_pipe(). Due to the unlock, commit 73ed5d25dce0 ("af-unix: fix use-after-free with concurrent readers while splicing") added a safeguard in unix_stream_read_generic(); we had to bump the skb refcount before calling ->recv_actor() and then check if the skb was consumed by a concurrent reader. However, the pipe side locking was refactored, and since commit 25869262ef7a ("skb_splice_bits(): get rid of callback"), we can call splice_to_pipe() without releasing unix_sk(sk)->iolock. Now, the skb is always alive after the ->recv_actor() callback, so let's remove the unnecessary drop_skb logic. This is mostly the revert of commit 73ed5d25dce0 ("af-unix: fix use-after-free with concurrent readers while splicing").

TCP_CLOSE may or may not have current/rnext keys and should not be considered "established". The fast-path for TCP_CLOSE is SKB_DROP_REASON_TCP_CLOSE. This is what tcp_rcv_state_process() does anyways. Add an early drop path to not spend any time verifying segment signatures for sockets in TCP_CLOSE state.

2024-06-01net/ncsi: Fix the multi thread manner of NCSI driverDelphineCCChiu
Currently NCSI driver will send several NCSI commands back to back without waiting the response of previous NCSI command or timeout in some state when NIC have multi channel. This operation against the single thread manner defined by NCSI SPEC(section 6.3.2.3 in DSP0222_1.1.1) According to NCSI SPEC(section 6.2.13.1 in DSP0222_1.1.1), we should probe one channel at a time by sending NCSI commands (Clear initial state, Get version ID, Get capabilities...), than repeat this steps until the max number of channels which we got from NCSI command (Get capabilities) has been probed.
