When changing the interface type we also need to update the bss_num, the driver private data is searched based on a unique (bss_type, bss_num) tuple, therefore every time bss_type changes, bss_num must also change. This fixes for example an issue in which, after the mode changed, a wireless scan on the changed interface would not finish, leading to repeated -EBUSY messages to userspace when other scan requests were sent.

The default netdev interface exposed by WILC1000 is registered at probe, but the chip mac address is not known until ndo_open, which will load and start chip firmware and then retrieve stored MAC address from it. As a consequence, the interface has uninitialized value (00:00:00:00:00) until a user brings up the interface. Fix MAC address at probe by setting the following steps: - at probe, read MAC address directly from fuse - whenever a new netdevice is created, apply saved mac address (which can be a user-provided address, or the eFuse Mac address if no address has been passed by user) - whenever an interface is brought up for the first time (and so the firmware is loaded and started), enforce netdevice mac address to the chip (in case user has changed it) Reported-by:

In order to be able to read raw registers (eg the nv mac address) in wilc1000 during probe before the firmware is loaded and running, we need to run the basic sdio functions initialization, but then we also need to properly deinitialize those right after, to preserve the current driver behavior (keeping the chip idle/unconfigured until the corresponding interface is brought up). Calling wilc_sdio_deinit in its current form is not enough because it merely resets an internal flag. Implement a deinit sequence which symmetrically reset all steps performed in wilc_sdio_init (only for parts activating/deactivating features, for the sake of simplicity, let's ignore blocks size configuration reset) Signed-off-by:

wilc driver currently reads and sets mac address by firmware calls. It means that we can not access mac address if no interface has been brought up (so firmware is up and running). Another way to get mac address is to read it directly from eFUSE. Add a function helper to read the mac address written in eFuse, without firmware assistance Signed-off-by:

SDIO/SPI probes functions automatically add a default wlan interface on top of registered wiphy, through wilc_cfg80211_init which in turn calls wilc_netdev_ifc_init. However, bus is still not fully initialized when we register corresponding net device (for example we still miss some private driver data pointers), which for example makes it impossible to retrieve MAC address from chip (which is supposed to be set on net device before its registration) before registering net device. More generally, net device registration should not be done until driver has fully initialized everything and is ready to handle any operation on the net device. Prevent net device from being registered so early by doing it at the end of probe functions. Apply this logic to both sdio and spi buses. Signed-off-by:

net device registration is currently done in wilc_netdev_ifc_init but other initialization operations are still done after this registration. Since net device is assumed to be usable right after registration, it should be the very last step of initialization. Move netdev registration at the very end of wilc_netdev_ifc_init to let this function completely initialize netdevice before registering it. Signed-off-by:

Merge tag 'wireless-next-2024-05-08' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next Kalle Valo says: ==================== wireless-next patches for v6.10 The third, and most likely the last, "new features" pull request for v6.10 with changes both in stack and in drivers. In ath12k and rtw89 we disabled Wireless Extensions just like with iwlwifi earlier. Wi-Fi 7 devices will not support Wireless Extensions (WEXT) anymore so if someone is still using the legacy WEXT interface it's time to switch to nl80211 now! We merged wireless into wireless-next as we decided not to send a wireless pull request to v6.9 this late in the cycle. Also an immutable branch with MHI subsystem was merged to get ath11k and ath12k hibernation working. Major changes: mac80211/cfg80211 * handle color change per link mt76 * mt7921 LED control * mt7925 EHT radiotap support * mt7920e PCI support ath12k * debugfs support * dfs_simulate_radar debugfs file * disable Wireless Extensions * suspend and hibernation support * ACPI support * refactoring in preparation of multi-link support ath11k * support hibernation (required changes in qrtr and MHI subsystems) * ieee80211-freq-limit Device Tree property support ath10k * firmware-name Device Tree property support rtw89 * complete features of new WiFi 7 chip 8922AE including BT-coexistence and WoWLAN * use BIOS ACPI settings to set TX power and channels * disable Wireless Extensios on Wi-Fi 7 devices iwlwifi * block_esr debugfs file * support again firmware API 90 (was reverted earlier) * provide channel survey information for Automatic Channel Selection (ACS) * tag 'wireless-next-2024-05-08' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next: (214 commits) wifi: mwl8k: initialize cmd->addr[] properly wifi: iwlwifi: Ensure prph_mac dump includes all addresses wifi: iwlwifi: mvm: don't request statistics in restart wifi: iwlwifi: mvm: exit EMLSR if secondary link is not used wifi: iwlwifi: mvm: add beacon template version 14 wifi: iwlwifi: mvm: align UATS naming with firmware wifi: iwlwifi: Force SCU_ACTIVE for specific platforms wifi: iwlwifi: mvm: record and return channel survey information wifi: iwlwifi: mvm: add the firmware API for channel survey wifi: iwlwifi: mvm: Fix race in scan completion wifi: iwlwifi: mvm: Add a print for invalid link pair due to bandwidth wifi: iwlwifi: mvm: add a debugfs for reading EMLSR blocking reasons wifi: iwlwifi: mvm: Add active EMLSR blocking reasons prints wifi: iwlwifi: bump FW API to 90 for BZ/SC devices wifi: iwlwifi: mvm: fix primary link setting wifi: iwlwifi: mvm: use already determined cmd_id wifi: iwlwifi: mvm: don't reset link selection during restart wifi: iwlwifi: Print EMLSR states name wifi: iwlwifi: mvm: Block EMLSR when a p2p/softAP vif is active wifi: iwlwifi: mvm: fix typo in debug print ... ==================== Link: https://lore.kernel.org/r/20240508120726.85A10C113CC@smtp.kernel.orgSigned-off-by:

Run tools/testing/selftest/net/csum.c as part of drv-net. This binary covers multiple scenarios, based on arguments given, for both IPv4 and IPv6: - Accept UDP correct checksum - Detect UDP invalid checksum - Accept TCP correct checksum - Detect TCP invalid checksum - Transmit UDP: basic checksum offload - Transmit UDP: zero checksum conversion The test direction is reversed between receive and transmit tests, so that the NIC under test is always the local machine. In total this adds up to 12 testcases, with more to follow. For conciseness, I replaced individual functions with a function factory. Also detect hardware offload feature availability using Ethtool netlink and skip tests when either feature is off. This need may be common for offload feature tests and eventually deserving of a thin wrapper in lib.py. Missing are the PF_PACKET based send tests ('-P'). These use virtio_net_hdr to program hardware checksum offload. Which requires looking up the local MAC address and (harder) the MAC of the next hop. I'll have to give it some though how to do that robustly and where that code would belong.

Currently the ipq806x dwmac driver is almost always used attached to the CPU port of a switch and phy-mode was always set to "rgmii" or "sgmii". Some device came up with a special configuration where the PHY is directly attached to the GMAC port and in those case phy-mode needs to be set to "rgmii-id" to make the PHY correctly work and receive packets. Since the driver supports only "rgmii" and "sgmii" mode, when "rgmii-id" (or variants) mode is set, the mode is rejected and probe fails. Add support also for these phy-modes to correctly setup PHYs that requires delay applied to tx/rx. Signed-off-by:

Enhance the error reporting mechanism in the switchdev framework to provide more informative and user-friendly error messages. Following feedback from users struggling to understand the implications of error messages like "failed (err=-28) to add object (id=2)", this update aims to clarify what operation failed and how this might impact the system or network. With this change, error messages now include a description of the failed operation, the specific object involved, and a brief explanation of the potential impact on the system. This approach helps administrators and developers better understand the context and severity of errors, facilitating quicker and more effective troubleshooting. Example of the improved logging: [ 70.516446] ksz-switch spi0.0 uplink: Failed to add Port Multicast Database entry (object id=2) with error: -ENOSPC (-28). [ 70.516446] Failure in updating the port's Multicast Database could lead to multicast forwarding issues. [ 70.516446] Current HW/SW setup lacks sufficient resources. This comprehensive update includes handling for a range of switchdev object IDs, ensuring that most operations within the switchdev framework benefit from clearer error reporting.

Introduce a tracepoint for icmp_send, which can help users to get more detail information conveniently when icmp abnormal events happen. 1. Giving an usecase example: ============================= When an application experiences packet loss due to an unreachable UDP destination port, the kernel will send an exception message through the icmp_send function. By adding a trace point for icmp_send, developers or system administrators can obtain detailed information about the UDP packet loss, including the type, code, source address, destination address, source port, and destination port. This facilitates the trouble-shooting of UDP packet loss issues especially for those network-service applications. 2. Operation Instructions: ========================== Switch to the tracing directory. cd /sys/kernel/tracing Filter for destination port unreachable. echo "type==3 && code==3" > events/icmp/icmp_send/filter Enable trace event. echo 1 > events/icmp/icmp_send/enable 3.

Oleksij Rempel says: ==================== add DCB and DSCP support for KSZ switches This patch series is aimed at improving support for DCB (Data Center Bridging) and DSCP (Differentiated Services Code Point) on KSZ switches. The main goal is to introduce global DSCP and PCP (Priority Code Point) mapping support, addressing the limitation of KSZ switches not having per-port DSCP priority mapping. This involves extending the DSA framework with new callbacks for managing trust settings for global DSCP and PCP maps. Additionally, we introduce IEEE 802.1q helpers for default configurations, benefiting other drivers too. Change logs are in separate patches. Compared to v6 this series includes some new patches for DSCP global mapping support and QoS selftest script for KSZ9477 switches. ==================== Signed-off-by: -

Microchip KSZ and LAN variants do not have per port DSCP priority configuration. Instead there is a global DSCP mapping table. This patch provides write access to this global DSCP map. In case entry is "deleted", we map corresponding DSCP entry to a best effort prio, which is expected to be the default priority for all untagged traffic. Signed-off-by:

Some switches like Microchip KSZ variants do not support per port DSCP priority configuration. Instead there is a global DSCP mapping table. To handle it, we will accept set/del request to any of user ports to make global configuration and update dcb app entries for all other ports. Signed-off-by:
