Since limited tracking device per condition, this feature is to support tracking multiple devices concurrently. When a pattern monitor detects the device, this feature issues an address monitor for tracking that device. Let pattern monitor can keep monitor new devices. This feature adds an address filter when receiving a LE monitor device event which monitor handle is for a pattern, and the controller started monitoring the device. And this feature also has cancelled the monitor advertisement from address filters when receiving a LE monitor device event when the controller stopped monitoring the device specified by an address and monitor handle. Below is an example to know the feature adds the address filter. //Add MSFT pattern monitor < HCI Command: Vendor (0x3f|0x00f0) plen 14 #142 [hci0] 55.552420 03 b8 a4 03 ff 01 01 06 09 05 5f 52 45 46 .........._REF > HCI Event: Command Complete (0x0e) plen 6 #143 [hci0] 55.653960 Vendor (0x3f|0x00f0) ncmd 2 Status: Success (0x00) 03 00 //Got event from the pattern monitor > HCI Event: Vendor (0xff) plen 18 #148 [hci0] 58.384953 23 79 54 33 77 88 97 68 02 00 fb c1 29 eb 27 b8 #yT3w..h....).'. 00 01 .. //Add MSFT address monitor (Sample address: B8:27:EB:29:C1:FB) < HCI Command: Vendor (0x3f|0x00f0) plen 13 #149 [hci0] 58.385067 03 b8 a4 03 ff 04 00 fb c1 29 eb 27 b8 .........).'. //Report to userspace about found device (ADV Monitor Device Found) @ MGMT Event: Unknown (0x002f) plen 38 {0x0003} [hci0] 58.680042 01 00 fb c1 29 eb 27 b8 01 ce 00 00 00 00 16 00 ....).'......... 0a 09 4b 45 59 42 44 5f 52 45 46 02 01 06 03 19 ..KEYBD_REF..... c1 03 03 03 12 18 ...... //Got event from address monitor > HCI Event: Vendor (0xff) plen 18 #152 [hci0] 58.672956 23 79 54 33 77 88 97 68 02 00 fb c1 29 eb 27 b8 #yT3w..h....).'. 01 01 Signed-off-by:Alex Lu <alex_lu@realsil.com.cn> Signed-off-by:

New Intel platforms supports reset of Bluetooth device via ACPI DSM methods. The legacy reset mechanism via GPIO will be deprecated in future. This patch checks the platform support for reset methods and if supported uses the same instead of legacy GPIO toggling method. ACPI firmware supports two types of reset method based on NIC card. (Discrete or Integrated). 1. VSEC Type - Vendor Specific Extended Capability. Here BT_EN and BT_IF_SELECT lines are driven by a register in PCH cluster. This interface is supported on discrete BT solution. 2. WDISABLE2 - In this soluton, W_DISABLE2 pin in M.2 is connected to physical GPIO from PCH. The DSM interface shall toggle this to recover from error. Signed-off-by:

This adds support for creating multiple BIGs. According to spec, each BIG shall have an unique handle, and each BIG should be associated with a different advertising handle. Otherwise, the LE Create BIG command will fail, with error code Command Disallowed (for reusing a BIG handle), or Unknown Advertising Identifier (for reusing an advertising handle). The btmon snippet below shows an exercise for creating two BIGs for the same controller, by opening two isotest instances with the following command: tools/isotest -i hci0 -s 00:00:00:00:00:00 < HCI Command: LE Create Broadcast Isochronous Group (0x08|0x0068) plen 31 Handle: 0x00 Advertising Handle: 0x01 Number of BIS: 1 SDU Interval: 10000 us (0x002710) Maximum SDU size: 40 Maximum Latency: 10 ms (0x000a) RTN: 0x02 PHY: LE 2M (0x02) Packing: Sequential (0x00) Framing: Unframed (0x00) Encryption: 0x00 Broadcast Code: 00000000000000000000000000000000 > HCI Event: Command Status (0x0f) plen 4 LE Create Broadcast Isochronous Group (0x08|0x0068) ncmd 1 Status: Success (0x00) > HCI Event: LE Meta Event (0x3e) plen 21 LE Broadcast Isochronous Group Complete (0x1b) Status: Success (0x00) Handle: 0x00 BIG Synchronization Delay: 912 us (0x000390) Transport Latency: 912 us (0x000390) PHY: LE 2M (0x02) NSE: 3 BN: 1 PTO: 1 IRC: 3 Maximum PDU: 40 ISO Interval: 10.00 msec (0x0008) Connection Handle #0: 10 < HCI Command: LE Create Broadcast Isochronous Group (0x08|0x0068) Handle: 0x01 Advertising Handle: 0x02 Number of BIS: 1 SDU Interval: 10000 us (0x002710) Maximum SDU size: 40 Maximum Latency: 10 ms (0x000a) RTN: 0x02 PHY: LE 2M (0x02) Packing: Sequential (0x00) Framing: Unframed (0x00) Encryption: 0x00 Broadcast Code: 00000000000000000000000000000000 > HCI Event: Command Status (0x0f) plen 4 LE Create Broadcast Isochronous Group (0x08|0x0068) ncmd 1 Status: Success (0x00) Signed-off-by:Iulia Tanasescu <iulia.tanasescu@nxp.com> Signed-off-by:

LE Create CIS command shall not be sent before all CIS Established events from its previous invocation have been processed. Currently it is sent via hci_sync but that only waits for the first event, but there can be multiple. Make it wait for all events, and simplify the CIS creation as follows: Add new flag HCI_CONN_CREATE_CIS, which is set if Create CIS has been sent for the connection but it is not yet completed. Make BT_CONNECT state to mean the connection wants Create CIS. On events after which new Create CIS may need to be sent, send it if possible and some connections need it. These events are: hci_connect_cis, iso_connect_cfm, hci_cs_le_create_cis, hci_le_cis_estabilished_evt. The Create CIS status/completion events shall queue new Create CIS only if at least one of the connections transitions away from BT_CONNECT, so that we don't loop if controller is sending bogus events. This fixes sending multiple CIS Create for the same CIS in the "ISO AC 6(i) - Success" BlueZ test case: < HCI Command: LE Create Co..

It is required for some configurations to have multiple BISes as part of the same BIG. Similar to the flow implemented for unicast, DEFER_SETUP will also be used to bind multiple BISes for the same BIG, before starting Periodic Advertising and creating the BIG. The user will have to open a new socket for each BIS. By setting the BT_DEFER_SETUP socket option and calling connect, a new connection will be added for the BIG and advertising handle set by the socket QoS parameters. Since all BISes will be bound for the same BIG and advertising handle, the socket QoS options and base parameters should match for all connections. By calling connect on a socket that does not have the BT_DEFER_SETUP option set, periodic advertising will be started and the BIG will be created, with a BIS for each previously bound connection. Since a BIG cannot be reconfigured with additional BISes after creation, no more connections can be bound for the BIG after the start periodic advertising and create BIG commands have been queued. The bis_cleanup function has also been updated, so that the advertising set and the BIG will not be terminated unless there are no more bound or connected BISes. The HCI_CONN_BIG_CREATED connection flag has been added to indicate that the BIG has been successfully created. This flag is checked at bis_cleanup, so that the BIG is only terminated if the HCI_LE_Create_BIG_Complete has been received. This implementation has been tested on hardware, using the "isotest" tool with an additional command line option, to specify the number of BISes to create as part of the desired BIG: tools/isotest -i hci0 -s 00:00:00:00:00:00 -N 2 -G 1 -T 1 The btmon log shows that a BIG containing 2 BISes has been created: < HCI Command: LE Create Broadcast Isochronous Group (0x08|0x0068) plen 31 Handle: 0x01 Advertising Handle: 0x01 Number of BIS: 2 SDU Interval: 10000 us (0x002710) Maximum SDU size: 40 Maximum Latency: 10 ms (0x000a) RTN: 0x02 PHY: LE 2M (0x02) Packing: Sequential (0x00) Framing: Unframed (0x00) Encryption: 0x00 Broadcast Code: 00000000000000000000000000000000 > HCI Event: Command Status (0x0f) plen 4 LE Create Broadcast Isochronous Group (0x08|0x0068) ncmd 1 Status: Success (0x00) > HCI Event: LE Meta Event (0x3e) plen 23 LE Broadcast Isochronous Group Complete (0x1b) Status: Success (0x00) Handle: 0x01 BIG Synchronization Delay: 1974 us (0x0007b6) Transport Latency: 1974 us (0x0007b6) PHY: LE 2M (0x02) NSE: 3 BN: 1 PTO: 1 IRC: 3 Maximum PDU: 40 ISO Interval: 10.00 msec (0x0008) Connection Handle #0: 10 Connection Handle #1: 11 < HCI Command: LE Setup Isochronous Data Path (0x08|0x006e) plen 13 Handle: 10 Data Path Direction: Input (Host to Controller) (0x00) Data Path: HCI (0x00) Coding Format: Transparent (0x03) Company Codec ID: Ericsson Technology Licensing (0) Vendor Codec ID: 0 Controller Delay: 0 us (0x000000) Codec Configuration Length: 0 Codec Configuration: > HCI Event: Command Complete (0x0e) plen 6 LE Setup Isochronous Data Path (0x08|0x006e) ncmd 1 Status: Success (0x00) Handle: 10 < HCI Command: LE Setup Isochronous Data Path (0x08|0x006e) plen 13 Handle: 11 Data Path Direction: Input (Host to Controller) (0x00) Data Path: HCI (0x00) Coding Format: Transparent (0x03) Company Codec ID: Ericsson Technology Licensing (0) Vendor Codec ID: 0 Controller Delay: 0 us (0x000000) Codec Configuration Length: 0 Codec Configuration: > HCI Event: Command Complete (0x0e) plen 6 LE Setup Isochronous Data Path (0x08|0x006e) ncmd 1 Status: Success (0x00) Handle: 11 < ISO Data TX: Handle 10 flags 0x02 dlen 44 < ISO Data TX: Handle 11 flags 0x02 dlen 44 > HCI Event: Number of Completed Packets (0x13) plen 5 Num handles: 1 Handle: 10 Count: 1 > HCI Event: Number of Completed Packets (0x13) plen 5 Num handles: 1 Handle: 11 Count: 1 Signed-off-by: -

When running vlan test (bridge_vlan_aware/unaware.sh), there were some failure due to the lack .port_bridge_flag function to disable port flooding. Implement this operation for BR_LEARNING, BR_FLOOD, BR_MCAST_FLOOD and BR_BCAST_FLOOD. Since .port_bridge_flags affects the bits disabling learning for a port, ensure that any other modification on the same register done by a5psw_port_stp_state_set is in sync by using the port learning state to enable/disable learning on the port.

.port_bridge_flags will be added and allows to modify the flood mask independently for each port. Keeping the existing bridged_ports write in a5psw_flooding_set_resolution() would potentially messed up this.

The current implementation does not allow the user to enable both hw-tc-offload and ntuple features on the interface. These checks are added as TC flower offload and ntuple features internally configures the same hardware resource MCAM. But TC HTB offload configures the transmit scheduler which can be safely enabled on the interface with ntuple feature. This patch adds the same and ensures only TC flower offload and ntuple features are mutually exclusive. Signed-off-by:

But even if the "usable" and "all" variables are NULL, they can still work, because value will be checked in kfree_rcu.

If netdev_mc_count() is not zero and not IFF_ALLMULTI, filter incoming multicast packets. The chip has a Multicast Address Hash Table for allowed multicast addresses, so we fill it. Implement .ndo_set_rx_mode and recalculate multicast hash table. Also observe change of IFF_PROMISC and IFF_ALLMULTI netdev flags. Signed-off-by:

When gso.hdr_len is zero and a packet is transmitted via write() or writev(), all payload is treated as header which requires a contiguous memory allocation. This allocation request is harder to satisfy, and may even fail if there is enough fragmentation. Note that sendmsg() code path limits the linear copy length, so this change makes write()/writev() and sendmsg() paths more consistent. Signed-off-by:
