2022-12-12Bluetooth: hci_bcm: Add CYW4373A0 supportMarek Vasut
CYW4373A0 is a Wi-Fi + Bluetooth combo device from Cypress. This chip is present e.g. on muRata 2AE module. This chip has additional quirk where the HCI command 0xfc45, used on older chips to switch UART clock from 24 MHz to 48 MHz, to support baudrates over 3 Mbdps, is no longer recognized by this newer chip. This newer chip can configure the 4 Mbdps baudrate without the need to issue HCI command 0xfc45, so add flag to indicate this and do not issue the command on this chip to avoid failure to set 4 Mbdps baud rate. It is not clear whether there is a way to determine which chip does and which chip does not support the HCI command 0xfc45, other than trial and error.

2022-12-12Bluetooth: virtio_bt: fix device removalMichael S. Tsirkin
Device removal is clearly out of virtio spec: it attempts to remove unused buffers from a VQ before invoking device reset. To fix, make open/close NOPs and do all cleanup/setup in probe/remove. NB: This is a hacky way to handle this - virtbt_{open,close} as NOP is not really what a driver is supposed to be doing. These are transport enable/disable callbacks from the BT core towards the driver. It maps to a device being enabled/disabled by something like bluetoothd for example. So if disabled, users expect that no resources/queues are in use. It does work with all other transports like USB, SDIO, UART etc. There should be no buffer used if the device is powered off. We also don’t have any USB URBs in-flight if the transport is not active. The way to implement a proper fix would be using vq reset if supported, or even using a full device reset. The cost of the hack is a single skb wasted on an unused bt device. NB2: with this fix in place driver still suffers from a race condition if an interrupt triggers while device is being reset. To fix, in the virtbt_close() callback we should deactivate all interrupts.

2022-12-12Bluetooth: Work around SCO over USB HCI design defectNicolas Cavallari
The USB interface between the host and the bluetooth adapter used for SCO packets uses an USB isochronous endpoint with a fragmentation scheme that does not tolerate errors. Except USB isochronous transfers do not provide a reliable stream with guaranteed delivery. (There is no retry on error, see USB spec v2.0 5.6 and 8.5.5.) To fragment a packet, the bluetooth HCI simply splits it in parts and transfer them as-is. The receiver is expected to reconstruct the packet by assuming the first fragment contains the header and parsing its size field. There is no error detection either. If a fragment is lost, the end result is that the kernel is no longer synchronized and will pass malformed data to the upper layers, since it has no way to tell if the first fragment is an actual first fragment or a continuation fragment. Resynchronization can only happen by luck and requires an unbounded amount of time. The typical symptom for a HSP/HFP bluetooth headset is that the microphone stops working and dmesg contains piles of rate-limited "Bluetooth: hci0: SCO packet for unknown connection handle XXXX" errors for an indeterminate amount of time, until the kernel accidentally resynchronize. A workaround is to ask the upper layer to prevalidate the first fragment header. This is not possible with user channels so this workaround is disabled in this case. This problem is the most severe when using an ath3k adapter on an i.MX 6 board, where packet loss occur regularly, possibly because it is an USB1 device connected on an USB2 hub and this is a special case requiring split transactions.

2022-12-12sctp: sysctl: make extra pointers netns awareFiro Yang
Recently, a customer reported that from their container whose net namespace is different to the host's init_net, they can't set the container's net.sctp.rto_max to any value smaller than init_net.sctp.rto_min. For instance, Host: sudo sysctl net.sctp.rto_min net.sctp.rto_min = 1000 Container: echo 100 > /mnt/proc-net/sctp/rto_min echo 400 > /mnt/proc-net/sctp/rto_max echo: write error: Invalid argument This is caused by the check made from this'commit 4f3fdf3bc59c ("sctp: add check rto_min and rto_max in sysctl")' When validating the input value, it's always referring the boundary value set for the init_net namespace. Having container's rto_max smaller than host's init_net.sctp.rto_min does make sense. Consider that the rto between two containers on the same host is very likely smaller than it for two hosts. So to fix this problem, as suggested by Marcelo, this patch makes the extra pointers of rto_min, rto_max, pf_retrans, and ps_retrans point to the corresponding variables from the newly created net namespace while the new net namespace is being registered in sctp_sysctl_net_register.
