Even if this is not a real bug since mt76_connac_mcu_alloc_wtbl_req routine can fails just if nskb is NULL , always check return value from mt76_connac_mcu_alloc_wtbl_req in order to avoid possible future mistake. Reported-by:

When operating two VAP on a MT7610 with encryption (PSK2, SAE, OWE), only the first one to be created will transmit properly encrypteded frames. All subsequently created VAPs will sent out frames with the payload left unencrypted, breaking multicast traffic (ICMP6 NDP) and potentially disclosing information to a third party. Disable GTK offloading and encrypt these frames in software to circumvent this issue. THis only seems to be necessary on MT7610 chips, as MT7612 is not affected from our testing. Signed-off-by:

Currently the expression ~nic_conf1 is always true because nic_conf1 is a u16 and according to 6.5.3.3 of the C standard the ~ operator promotes the u16 to an integer before flipping all the bits. Thus the top 16 bits of the integer result are all set so the expression is always true. If the intention was to flip all the bits of nic_conf1 then casting the integer result back to a u16 is a suitabel fix. Interestingly static analyzers seem to thing a bitwise ! should be used instead of ~ for this scenario, so I think the original intent of the expression may need some extra consideration.

Although FW crash logs are already supported for dumping in driver, the logs may not be sufficient to analyze field issues. To improve this part, we add a support to dump FW memory. When driver receives FW crash notifications, driver uses DDMA, which is a HW ability, to copy specified FW memory to FW fifo. Driver can then dump these information from FW fifo. With this support, not only FW crash log but also specified FW memory will be dumped while FW crash. Besides, specified registers are also dumped. This feature is implemeted on 8822C first due to difference of FW layouts between ICs. In addition, we add a debugfs to trigger FW crash. It can simulate the process of crash, dump and reset. Through it, we can also check if a reset is ongoing. Signed-off-by:

Ido Schimmel says: ==================== psample: Add additional metadata attributes This series extends the psample module to expose additional metadata to user space for packets sampled via act_sample. The new metadata (e.g., transit delay) can then be consumed by applications such as hsflowd [1] for better network observability. netdevsim is extended with a dummy psample implementation that periodically reports "sampled" packets to the psample module. In addition to testing of the psample module, it enables the development and demonstration of user space applications (e.g., hsflowd) that are interested in the new metadata even without access to specialized hardware (e.g., Spectrum ASIC) that can provide it. mlxsw is also extended to provide the new metadata to psample. A Wireshark dissector for psample netlink packets [2] will be submitted upstream after the kernel patches are accepted. In addition, a libpcap capture module for psample is currently in the works. Eventually, users should be able to run: # tshark -i psample In order to consume sampled packets along with their metadata. Series overview: Patch #1 makes it easier to extend the metadata provided to psample Patch #2 adds the new metadata attributes to psample Patch #3 extends netdevsim to periodically report "sampled" packets to psample. Various debugfs knobs are added to control the reporting Patch #4 adds a selftest over netdevsim Patches #5-#10 gradually add support for the new metadata in mlxsw Patch #11 adds a selftest over mlxsw [1] https://sflow.org/draft4_sflow_transit.txt [2] https://gitlab.com/amitcohen1/wireshark/-/commit/3d711143024e032aef1b056dd23f0266c54fab56 ==================== Signed-off-by:

The function resolves the psample sampling group from the Rx port because this is the only form of sampling the driver currently supports. Subsequent patches are going to add support for Tx-based and policy-based sampling, in which case the sampling group would not be resolved from the Rx port. Therefore, move this code to the Rx-specific sampling listener. Signed-off-by:

Allow netdevsim to report "sampled" packets to the psample module by periodically generating packets from a work queue. The behavior can be enabled / disabled (default) and the various meta data attributes can be controlled via debugfs knobs. This implementation enables both testing of the psample module with all the optional attributes as well as development of user space applications on top of psample such as hsflowd and a Wireshark dissector for psample generic netlink packets.
