In some corner cases, the peer handing an incoming ADD_ADDR option, can receive a retransmitted ADD_ADDR for the same address before the subflow creation completes. We can avoid the above issue by generating and sending the ADD_ADDR echo before starting the MPJ subflow connection. This slightly changes the behaviour of the packetdrill tests as the ADD_ADDR echo packet is sent earlier. Acked-by:

Network drivers can call to netif_get_num_default_rss_queues to get the default number of receive queues to use. Right now, this default number is min(8, num_online_cpus()). Instead, as suggested by Jakub, use the number of physical cores divided by 2 as a way to avoid wasting CPU resources and to avoid using both CPU threads, but still allowing to scale for high-end processors with many cores. As an exception, select 2 queues for processors with 2 cores, because otherwise it won't take any advantage of RSS despite being SMP capable. Tested: Processor Intel Xeon E5-2620 (2 sockets, 6 cores/socket, 2 threads/core). NIC Broadcom NetXtreme II BCM57810 (10GBps). Ran some tests with `perf stat iperf3 -R`, with parallelisms of 1, 8 and 24, getting the following results: - Number of queues: 6 (instead of 8) - Network throughput: not affected - CPU usage: utilized 0.05-0.12 CPUs more than before (having 24 CPUs this is only 0.2-0.5% higher) - Reduced the number of context switches by 7-50%, being more noticeable when using a higher number of parallel threads.

The DSDT for the Asus TF103C specifies a IOAPIC IRQ for the HCI -> host IRQ but this is not correct. Unlike the previous entries in the table, this time the correct GPIO to use instead is known; and the TF103C is battery powered making runtime-pm support more important. Extend the bcm_broken_irq_dmi_table mechanism to allow specifying the right GPIO instead of just always disabling runtime-pm and add an entry to it for the Asus TF103C. Signed-off-by:

The details are shown as the below: hci_register_dev would run queue_work(hdev->req_workqueue, &hdev->power_on) as WQ_HIGHPRI workqueue_struct to complete the power-on sequeunce and thus hci_power_on may run before sdio_set_drvdata is done in btmtksdio_probe. The hci_dev_do_open in hci_power_on would initialize the device and enable the interrupt and thus it is possible that btmtksdio_interrupt is being called right before sdio_set_drvdata is filled out. When btmtksdio_interrupt is being called and sdio_set_drvdata is not filled , the kernel oops is going to happen because btmtksdio_interrupt access an uninitialized pointer.

When an Advertisement Monitor is configured with SamplingPeriod 0xFF, the controller reports only one adv report along with the MSFT Monitor Device event. When an advertiser matches multiple monitors, some controllers send one adv report for each matched monitor; whereas, some controllers send just one adv report for all matched monitors. In such a case, report Adv Monitor Device Found event for each matched monitor. Signed-off-by:

Another subset of the more recent batch of Chinese clones aren't specs-compliant and seem to lock up whenever they receive a HCI_OP_SET_EVENT_FLT with flt_type set to zero/HCI_FLT_CLEAR_ALL, which on Linux (until the recent HCI state-machine refactor) happened right at BR/EDR setup. As there are other less-straightforward ways of reaching those operations, this patch is still relevant. So, while all the previous efforts to wrangle the herd of fake CSRs seem to be paying off (and these also get detected as such) we still need to take care of this quirk; testers seem to agree that these dongles tend to work well enough afterwards. From some cursory USB packet capture on Windows it seems like that driver doesn't appear to use this clear-all functionality at all. This patch was tested on some really popular AliExpress-style dongles, in my case marked as "V5.0". Chip markings: UG8413, the backside of the PCB says "USB Dangel" (sic). Here is the `hciconfig -a` output; for completeness: hci0: Type: Primary Bus: USB BD Address: 00:1A:7D:DA:7X:XX ACL MTU: 679:8 SCO MTU: 48:16 UP RUNNING PSCAN ISCAN Features: 0xbf 0x3e 0x4d 0xfa 0xdb 0x3d 0x7b 0xc7 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: RSWITCH SNIFF Link mode: PERIPHERAL ACCEPT Name: 'CSR8510 A10.'

There is a conflict between MediaTek wmt event and msft vendor extension logic in the core layer since 145373cb ("Bluetooth: Add framework for Microsoft vendor extension") was introduced because we changed the type of mediatek wmt event to the type of msft vendor event in the driver. But the purpose we reported mediatek event to the core layer is for the diagnostic purpose with that we are able to see the full packet trace via monitoring socket with btmon. Thus, it is harmless we keep the original type of mediatek vendor event here to avoid breaking the msft extension function especially they can be supported by Mediatek future devices. Signed-off-by:

Variable cur_len is being ininitialized with a value in the start of a for-loop but this is never read, it is being re-assigned a new value on the first statement in the for-loop. The initialization is redundant and can be removed. Cleans up clang scan build warning: net/bluetooth/mgmt.c:7958:14: warning: Although the value stored to 'cur_len' is used in the enclosing expression, the value is never actually read from 'cur_len' [deadcode.DeadStores] Signed-off-by:

Add test where sender sends two message, each with own data pattern. Reader tries to read first to broken buffer: it has three pages size, but middle page is unmapped. Then, reader tries to read second message to valid buffer. Test checks, that uncopied part of first message was dropped and thus not copied as part of second message. Signed-off-by:
