In original code architecture, sec CAM is a component of addr CAM. Hence, sec CAM could not be shared. After MLO, each link has its own addr CAM. However, one MLD PTK takes only one sec CAM but it needs to work on multiple links' addr CAMs. So, we now manage sec CAMs in global pool, and each of them is not bound to a single addr CAM now. before: +-----------------+ +--------------------+ | rtw89_{vif/sta} | ... | ieee80211_key_conf | +-----------------+ +--------------------+ ^ | V | hw_key_idx | | | V | +-- +----------+ addr_cam::key_idx | \ +---------+ | addr_cam |<>---------------------| |-------| sec_cam | +----------+ | / +---------+ +-- after: +----------------------+ +--------------------+ | rtw89_{vif/sta}_link | ... | ieee80211_key_conf | +----------------------+ +--------------------+ ^ | V | hw_key_idx | | | V | --+ +---------+ | +---------+ / | sec_cam_idx | global | | | sec_cam |-------| |----------------<>| sec_cam | | +---------+ \ | | pool | | ^ --+ +---------+ | | | (*) | +----------+ | | addr_cam |-------------+ +----------+ Signed-off-by:Zong-Zhe Yang <kevin_yang@realtek.com> Signed-off-by:

We did deinit CAM in STA iteration in VIF loop. But, the STA iteration missed to restrict the target VIF. So, if there are multiple VIFs, we would deinit a CAM multiple times. Now, fix it. Signed-off-by:

When there is beacon loss, for example due to unrelated Bluetooth devices transmitting music nearby, the wifi connection dies soon after the first beacon loss message: Apr 28 20:47:14 ideapad2 wpa_supplicant[1161]: wlp3s0f3u4: CTRL-EVENT-BEACON-LOSS Apr 28 20:47:15 ideapad2 wpa_supplicant[1161]: wlp3s0f3u4: CTRL-EVENT-DISCONNECTED bssid=... reason=4 locally_generated=1 Apr 28 20:47:24 ideapad2 wpa_supplicant[1161]: wlp3s0f3u4: CTRL-EVENT-BEACON-LOSS Apr 28 20:47:25 ideapad2 wpa_supplicant[1161]: wlp3s0f3u4: CTRL-EVENT-DISCONNECTED bssid=... reason=4 locally_generated=1 Apr 28 20:47:34 ideapad2 wpa_supplicant[1161]: wlp3s0f3u4: CTRL-EVENT-BEACON-LOSS Apr 28 20:47:35 ideapad2 wpa_supplicant[1161]: wlp3s0f3u4: CTRL-EVENT-DISCONNECTED bssid=... reason=4 locally_generated=1 When the beacon loss happens, mac80211 makes rtw88 transmit a QOS NULL frame and asks to confirm the ACK status. Even though rtw88 confirms to mac80211 that the QOS NULL was transmitted successfully, the connection still dies. This is because rtw88 is handing the QOS NULL back to mac80211 with skb->data pointing to the headroom (the TX descriptor) instead of ieee80211_hdr. Fix the disconnection by moving skb->data to the correct position before ieee80211_tx_status_irqsafe(). The problem was observed with RTL8811AU (TP-Link Archer T2U Nano) and the potential future rtw88_8821au driver. Also tested with RTL8811CU (Tenda U9). Cc: stable@vger.kernel.org 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.

Let's make all IPVS sysctls writtable even when network namespace is owned by non-initial user namespace. Let's make a few sysctls to be read-only for non-privileged users: - sync_qlen_max - sync_sock_size - run_estimation - est_cpulist - est_nice I'm trying to be conservative with this to prevent introducing any security issues in there. Maybe, we can allow more sysctls to be writable, but let's do this on-demand and when we see real use-case. This patch is motivated by user request in the LXC project [1].

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. Result View: ================ udp_client_erro-11370 [002] ...s.12 124.728002: icmp_send: icmp_send: type=3, code=3.

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.

KSZ88X3 switches have different behavior on different ports: - It seems to be not possible to disable VLAN PCP classification on port 2. It means, as soon as mutliqueue support is enabled, frames with VLAN tag will get PCP prios. This behavior do not affect Port 1 - it is possible to disable PCP prios. - DSCP classification is not working on Port 2. Since there are still usable configuration combinations, I added some quirks to make sure user will get appropriate error message if not possible configuration is chosen. Signed-off-by: -

Some usb drivers set small skb->truesize and break core networking stacks. In this patch, I removed one of the skb->truesize override. I also replaced one skb_clone() by an allocation of a fresh and small skb, to get minimally sized skbs, like we did in commit 1e2c6117 ("net: cdc_ncm: reduce skb truesize in rx path") and 4ce62d5b ("net: usb: ax88179_178a: stop lying about skb->truesize") Fixes: c9b37458 ("USB2NET : SR9700 : One chip USB 1.1 USB2NET SR9700Device Driver Support") Signed-off-by:
