There are multiple setup and shutdown functions for Intel device and the setup function to be used is depends on the USB PID/VID, which makes difficult to maintain the code and increases the code size. This patch adds combined setup and shutdown functions to provide a single entry point for all Intel devices and choose the setup functions based on the information read with HCI_Intel_Read_Version command. Starting from TyP device, the command and response parameters for HCI_Intel_Read_Version command are changed even though OCF remains same. However, the legacy devices still can handle the command without error even if it has a extra parameter, so to simplify the flow, the new command format is used to read the version information for both legacy and new (tlv based) format. Also, it also adds a routine to setup the hdev callbacks in btintel. Signed-off-by:

An earlier commit replaced using batostr to using %pMR sprintf for the construction of session->name. Static analysis detected that this new method can use a total of 21 characters (including the trailing '\0') so we need to increase the BTNAMSIZ from 18 to 21 to fix potential buffer overflows.

When the firmware hang or command no response, driver can reset the bluetooth mcu via USB to recovery it. The reset steps as follows. 1. Cancel USB transfer requests before reset. 2. It use speicific USB HW Register to reset Bluetooth MCU, at the same time, the USB Endpoint0 still keep alive. 3. Poll the USB HW register until reset is completed by Endpoint0. 4. To recovery unexpected USB state and behavior during resetting the Bluetooth MCU, the driver need to reset the USB device for MT7921. 5. After the reset is completed, the Bluetooth MCU need to re-setup, such as download patch, power-on sequence and etc. Signed-off-by:

Mediatek Bluetooth controller sends the FW log and FW dump via EP2. This patch creates an MTK specified callback(btusb_recv_acl_mtk) to replace the original one (hci_recv_frame) when an MTK controller is detected. The new callback will separate the firmware dump traffics from the ACL data to have them process separately. 1. Add a new field (recv_acl) to the btusb_data struct to store vendor-specific ACL callback handler. 2. Add the MTK-specific ACL callback handler (btusb_recv_acl_mtk) to process ACL data, debug log, and firmware dump. 3. The debug log traces LMP/LL events and connection quality reports. 4. The upper layer can use hci_channel_monitor to receive these packets. Example btmon: firmware debug log. 1. Enable firmware debug log. < HCI Command: Vendor (0x3f|0x005d) plen 4 00 00 02 02 .... > HCI Event: Command Complete (0x0e) plen 8 Vendor (0x3f|0x005d) ncmd 1 Status: Success (0x00) 00 00 02 02 .... 2.

Code was checking if random_addr and hdev->rpa match without first checking if the RPA has not been set (BDADDR_ANY), furthermore it was clearing HCI_RPA_EXPIRED before the command completes and the RPA is actually programmed which in case of failure would leave the expired RPA still set. Since advertising instance have a similar problem the clearing of HCI_RPA_EXPIRED has been moved to hci_event.c after checking the random address is in fact the hdev->rap and then proceed to set the expire timeout.

Turns out Hans de Goede completed the work I started last year trying to improve Chinese-clone detection of CSR controller chips. Quirk after quirk these Bluetooth dongles are more usable now. Even after a few BlueZ regressions; these clones are so fickle that some days they stop working altogether. Except on Windows, they work fine. But this force-suspend initialization quirk seems to mostly do the trick, after a lot of testing Bluetooth now seems to work *all* the time. The only problem is that the solution ended up being masked under a very stringent check; when there are probably hundreds of fake dongle models out there that benefit from a good reset. Make it so.

strcpy() performs no bounds checking on the destination buffer. This could result in linear overflows beyond the end of the buffer, leading to all kinds of misbehaviors. The safe replacement is strscpy() but in this case it is better to use the scnprintf to simplify the arithmetic. This is a previous step in the path to remove the strcpy() function entirely from the kernel. Signed-off-by:

Syzbot reported a corrupted list in kobject_add_internal [1]. This happens when multiple HCI_EV_SYNC_CONN_COMPLETE event packets with status 0 are sent for the same HCI connection. This causes us to register the device more than once which corrupts the kset list. As this is forbidden behavior, we add a check for whether we're trying to process the same HCI_EV_SYNC_CONN_COMPLETE event multiple times for one connection. If that's the case, the event is invalid, so we report an error that the device is misbehaving, and ignore the packet.

syzbot is hitting might_sleep() warning at hci_sock_dev_event() due to calling lock_sock() with rw spinlock held [1]. It seems that history of this locking problem is a trial and error. Commit b40df574 ("[PATCH] bluetooth: fix socket locking in hci_sock_dev_event()") in 2.6.21-rc4 changed bh_lock_sock() to lock_sock() as an attempt to fix lockdep warning. Then, commit 4ce61d1c ("[BLUETOOTH]: Fix locking in hci_sock_dev_event().") in 2.6.22-rc2 changed lock_sock() to local_bh_disable() + bh_lock_sock_nested() as an attempt to fix sleep in atomic context warning. Then, commit 4b5dd696 ("Bluetooth: Remove local_bh_disable() from hci_sock.c") in 3.3-rc1 removed local_bh_disable(). Then, commit e305509e ("Bluetooth: use correct lock to prevent UAF of hdev object") in 5.13-rc5 again changed bh_lock_sock_nested() to lock_sock() as an attempt to fix CVE-2021-3573. This difficulty comes from current implementation that hci_sock_dev_event(HCI_DEV_UNREG) is responsible for dropping all references from sockets because hci_unregister_dev() immediately reclaims resources as soon as returning from hci_sock_dev_event(HCI_DEV_UNREG). But the history suggests that hci_sock_dev_event(HCI_DEV_UNREG) was not doing what it should do. Therefore, instead of trying to detach sockets from device, let's accept not detaching sockets from device at hci_sock_dev_event(HCI_DEV_UNREG), by moving actual cleanup of resources from hci_unregister_dev() to hci_release_dev() which is called by bt_host_release when all references to this unregistered device (which is a kobject) are gone.

The LG LGSBWAC92/TWCM-K505D/EAT64454801/EAT64454802 (it goes by many names) is a combo WiFi/Bluetooth module that's used in several models of LG TVs. It uses the MediaTek MT7668AUN, which is already supported in btusb, but this device has a non-MediaTek VID:PID pair so to get it to work we just need to add it to the list of devices to probe.

The hci_suspend_notifier which was introduced last year, is causing problems for uart attached btrtl devices. These devices may loose their firmware and their baudrate setting over a suspend/resume. Since we don't even know the baudrate after a suspend/resume recovering from this is tricky. The driver solves this by treating these devices the same as USB BT HCIs which drop of the bus during suspend. Specifically the driver: 1. Simply unconditionally turns the device fully off during system-suspend to save maximum power. 2. Calls device_reprobe() from a workqueue to fully re-init the device from scratch on system-resume (unregistering the old HCI and registering a new HCI). This means that these devices do not benefit from the suspend / resume handling work done by the hci_suspend_notifier. At best this unnecessarily adds some time to the suspend/resume time. But in practice this is actually causing problems: 1. These btrtl devices seem to not like the HCI_OP_WRITE_SCAN_ENABLE( SCAN_DISABLED) request being send to them when entering the BT_SUSPEND_CONFIGURE_WAKE state. The same request send on BT_SUSPEND_DISCONNECT works fine, but the second one send (unnecessarily?) from the BT_SUSPEND_CONFIGURE_WAKE transition causes the device to hang: [ 573.497754] PM: suspend entry (s2idle) [ 573.554615] Filesystems sync: 0.056 seconds [ 575.837753] Bluetooth: hci0: Timed out waiting for suspend events [ 575.837801] Bluetooth: hci0: Suspend timeout bit: 4 [ 575.837925] Bluetooth: hci0: Suspend notifier action (3) failed: -110 2. The PM_POST_SUSPEND / BT_RUNNING transition races with the driver-unbinding done by the device_reprobe() work. If the hci_suspend_notifier wins the race it is talking to a dead device leading to the following errors being logged: [ 598.686060] Bluetooth: hci0: Timed out waiting for suspend events [ 598.686124] Bluetooth: hci0: Suspend timeout bit: 5 [ 598.686237] Bluetooth: hci0: Suspend notifier action (4) failed: -110 In both cases things still work, but the suspend-notifier is causing these ugly errors getting logged and ut increase both the suspend- and the resume-time by 2 seconds. This commit avoids these problems by disabling the hci_suspend_notifier.
