2023-02-13wifi: rtw89: coex: Force to update TDMA parameter when radio state changeChing-Te Ku1-0/+6
Force firmware to update TDMA parameter when enter/exit power saving. The TDMA instant feature will make firmware force update TDMA parameter immediately when the TDMA parameter H2C to firmware. Without this feature, it will have a low fail rate trigger Bluetooth audio sound glitch when Wi-Fi is under power saving. Or Wi-Fi fail to turn in to power save state.

2023-02-13wifi: mwifiex: Support SD8978 chipsetLukas Wunner5-5/+31
The Marvell SD8978 (aka NXP IW416) uses identical registers as SD8987, so reuse the existing mwifiex_reg_sd8987 definition. Note that mwifiex_reg_sd8977 and mwifiex_reg_sd8997 are likewise identical, save for the fw_dump_ctrl register: They define it as 0xf0 whereas mwifiex_reg_sd8987 defines it as 0xf9. I've verified that 0xf9 is the correct value on SD8978. NXP's out-of-tree driver uses 0xf9 for all of them, so there's a chance that 0xf0 is not correct in the mwifiex_reg_sd8977 and mwifiex_reg_sd8997 definitions. I cannot test that for lack of hardware, hence am leaving it as is. NXP has only released a firmware which runs Bluetooth over UART. Perhaps Bluetooth over SDIO is unsupported by this chipset. Consequently, only an "sdiouart" firmware image is referenced, not an alternative "sdsd" image.

2023-02-13wifi: brcmfmac: Rename Cypress 89459 to BCM4355Hector Martin3-10/+7
The commit that introduced support for this chip incorrectly claimed it is a Cypress-specific part, while in actuality it is just a variant of BCM4355 silicon (as evidenced by the chip ID). The relationship between Cypress products and Broadcom products isn't entirely clear but given what little information is available and prior art in the driver, it seems the convention should be that originally Broadcom parts should retain the Broadcom name. Thus, rename the relevant constants and firmware file. Also rename the specific 89459 PCIe ID to BCM43596, which seems to be the original subvariant name for this PCI ID (as defined in the out-of-tree bcmdhd driver). Since Cypress added this part and will presumably be providing its supported firmware, we keep the CYW designation for this device. We also drop the RAW device ID in this commit. We don't do this for the other chips since apparently some devices with them exist in the wild, but there is already a 4355 entry with the Broadcom subvendor and WCC firmware vendor, so adding a generic fallback to Cypress seems redundant (no reason why a device would have the raw device ID *and* an explicitly programmed subvendor).

2023-02-13wifi: libertas: only add RSN/WPA IE in lbs_add_wpa_tlvDoug Brown1-10/+18
The existing code only converts the first IE to a TLV, but it returns a value that takes the length of all IEs into account. When there is more than one IE (which happens with modern wpa_supplicant versions for example), the returned length is too long and extra junk TLVs get sent to the firmware, resulting in an association failure. Fix this by finding the first RSN or WPA IE and only adding that. This has the extra benefit of working properly if the RSN/WPA IE isn't the first one in the IE buffer. While we're at it, clean up the code to use the available structs like the other lbs_add_* functions instead of directly manipulating the TLV buffer.

In the previous code, TX timestamp accuracy was bad because the irq handler got the timestamp from the timestamp register at that time. This hardware has "Timestamp capture" feature which can store each TX timestamp into the timestamp descriptors. To improve TX timestamp accuracy, implement timestamp descriptors' handling.

In the previous code, the gptp flag was completely related to the !dir_tx in struct rswitch_gwca_queue because rswitch_gwca_queue_alloc() was called below: < In rswitch_txdmac_alloc() > err = rswitch_gwca_queue_alloc(ndev, priv, rdev->tx_queue, true, false, TX_RING_SIZE); So, dir_tx = true, and gptp = false. < In rswitch_rxdmac_alloc() > err = rswitch_gwca_queue_alloc(ndev, priv, rdev->rx_queue, false, true, RX_RING_SIZE); So, dir_tx = false, and gptp = true. In the future, a new queue handling for timestamp will be implemented and this gptp flag is confusable. So, remove the gptp flag.

2023-02-11selftests: forwarding: Add MDB dump test casesIdo Schimmel1-0/+99
The kernel maintains three markers for the MDB dump: 1. The last bridge device from which the MDB was dumped. 2. The last MDB entry from which the MDB was dumped. 3. The last port-group entry that was dumped. Add test cases for large scale MDB dump to make sure that all the configured entries are dumped and that the markers are used correctly. Specifically, create 2 bridges with 32 ports and add 256 MDB entries in which all the ports are member of. Test that each bridge reports 8192 (256 * 32) permanent entries. Do that with IPv4, IPv6 and L2 MDB entries. On my system, MDB dump of the above is contained in about 50 netlink messages. Example output: # ./bridge_mdb.sh [...] INFO: # Large scale dump tests TEST: IPv4 large scale dump tests [ OK ] TEST: IPv6 large scale dump tests [ OK ] TEST: L2 large scale dump tests [ OK ] [...] Signed-off-by: Ido Schimmel <idosch@nvidia.com> Reviewed-by: Petr Machata <petrm@nvidia.com> Acked-by: Nikolay Aleksandrov <razor@blackwall.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-02-11bridge: mcast: Move validation to a policyIdo Schimmel1-18/+27
Future patches are going to move parts of the bridge MDB code to the common rtnetlink code in preparation for VXLAN MDB support. To facilitate code sharing between both drivers, move the validation of the top level attributes in RTM_{NEW,DEL}MDB messages to a policy that will eventually be moved to the rtnetlink code. Use 'NLA_NESTED' for 'MDBA_SET_ENTRY_ATTRS' instead of NLA_POLICY_NESTED() as this attribute is going to be validated using different policies in the underlying drivers.

2023-02-11bridge: mcast: Remove pointless sequence generation counter assignmentIdo Schimmel1-2/+0
The purpose of the sequence generation counter in the netlink callback is to identify if a multipart dump is consistent or not by calling nl_dump_check_consistent() whenever a message is generated. The function is not invoked by the MDB code, rendering the sequence generation counter assignment pointless. Remove it. Note that even if the function was invoked, we still could not accurately determine if the dump is consistent or not, as there is no sequence generation counter for MDB entries, unlike nexthop objects, for example.
