ED/CCA needs to be disable before stopping the MAC to avoid hangs from tx being blocked. It must only be enabled again after the MAC has been started again. In many places this wasn't done properly, so fix this by always clearing the relevant ED/CCA bits in mt76x2_mac_stop and set it up again after channel change or calibration is done Signed-off-by:Felix Fietkau <nbd@nbd.name>

When mt76x0 and mt76x2 beacon code was unified, it changed the order in which beacon enable and beacon interval are configured. Configuring beacon enable before beacon interval can in some cases cause problems with the beacon timer, leading to clients not waking up properly from powersave mode. Fix this by changing the order back to interval first, then enable. Fixes: cc726268 ("mt76: move mt76x02_bss_info_changed in mt76x02-lib module") Cc: stable@vger.kernel.org Signed-off-by:

Andrew Lunn says: ==================== mv88e6xxx: Avoid false positive Lockdep splats When acquiring the GPIO interrupt line for the switch, it is possible to trigger lockdep splats. These are false positives, the mutex is in a different IRQ descriptor. But fix it anyway, since it could mask real locking issues. ==================== Signed-off-by: -

There is no need to hold the register lock while requesting the GPIO interrupt. By not holding it we can also avoid a false positive lockdep splat. Reported-by:

The patch enables returning 'type' in msghdr for records that are retrieved with MSG_PEEK in recvmsg. Further it prevents records peeked from socket from getting clubbed with any other record of different type when records are subsequently dequeued from strparser. For each record, we now retain its type in sk_buff's control buffer cb[]. Inside control buffer, record's full length and offset are already stored by strparser in 'struct strp_msg'. We store record type after 'struct strp_msg' inside 'struct tls_msg'. For tls1.2, the type is stored just after record dequeue. For tls1.3, the type is stored after record has been decrypted. Inside process_rx_list(), before processing a non-data record, we check that we must be able to return back the record type to the user application. If not, the decrypted records in tls context's rx_list is left there without consuming any data. Fixes: 692d7b5d ("tls: Fix recvmsg() to be able to peek across multiple records") Signed-off-by:

Presently the hns reset_type for the roce errors is set in the hclge_log_and_clear_rocee_ras_error function. This function is also called to detect and clear roce errors while enabling the rdma error interrupts. However there is no hns reset requested for this case. This can cause issue of wrong reset_type used with subsequent hns reset as the reset_type set in the above case was not cleared. This patch moves setting of hns reset_type for the roce errors from hclge_log_and_clear_rocee_ras_error function to hclge_handle_rocee_ras_error.

Ido Schimmel says: ==================== mlxsw: spectrum_acl: Don't take rtnl mutex for region rehash Jiri says: During region rehash, a new region is created with a more optimized set of masks (ERPs). When transitioning to the new region, all the rules from the old region are copied one-by-one to the new region. This transition can be time consuming and currently done under RTNL lock. In order to remove RTNL lock dependency during region rehash, introduce multiple smaller locks guarding dedicated structures or parts of them. That is the vast majority of this patchset. Only patch #1 is simple cleanup and patches 12-15 are improving or introducing new selftests. ==================== Signed-off-by: -
