Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next The following patchset contains Netfilter/IPVS updates for net-next: 1) Move bridge keys in nft_meta to nft_meta_bridge, from wenxu. 2) Support for bridge pvid matching, from wenxu. 3) Support for bridge vlan protocol matching, also from wenxu. 4) Add br_vlan_get_pvid_rcu(), to fetch the bridge port pvid from packet path. 5) Prefer specific family extension in nf_tables. 6) Autoload specific family extension in case it is missing. 7) Add synproxy support to nf_tables, from Fernando Fernandez Mancera. 8) Support for GRE encapsulation in IPVS, from Vadim Fedorenko. 9) ICMP handling for GRE encapsulation, from Julian Anastasov. 10) Remove unused parameter in nf_queue, from Florian Westphal. 11) Replace seq_printf() by seq_puts() in nf_log, from Markus Elfring. 12) Rename nf_SYNPROXY.h => nf_synproxy.h before this header becomes public. ==================== Signed-off-by: David S.

Pawel Dembicki says: ==================== net: dsa: Add Vitesse VSC73xx parallel mode Main goal of this patch series is to add support for CPU attached parallel bus in Vitesse VSC73xx switches. Existing driver supports only SPI mode. Second change is needed for devices in unmanaged state. V3: - fix commit messages and descriptions about memory-mapped I/O mode V2: - drop changes in compatible strings - make changes less invasive - drop mutex in platform part and move mutex from core to spi part - fix indentation - fix devm_ioremap_resource result check - add cover letter ==================== Signed-off-by: David S.

Driver allow to use devices with disabled iCPU only. Some devices have pre-initialised iCPU by bootloader. That state make switch unmanaged. This patch force reset if device is in unmanaged state. In the result chip lost internal firmware from RAM and it can be managed.

This driver (currently) only takes control of the switch chip over SPI and configures it to route packages around when connected to a CPU port. But Vitesse chip support also parallel interface. This patch split driver into two parts: core and spi. It is required for add support to another managing interface.

For these places are protected by rcu_read_lock, we change from rcu_dereference_rtnl to rcu_dereference, as there is no need to check if rtnl lock is held. For these places are protected by rtnl_lock, we change from rcu_dereference_rtnl to rtnl_dereference/rcu_dereference_protected, as no extra memory barriers are needed under rtnl_lock() which also protects tn->bearer_list[] and dev->tipc_ptr/b->media_ptr updating. rcu_dereference_rtnl will be only used in the places where it could be under rcu_read_lock or rtnl_lock.

BLE based 6LoWPAN networks are highly constrained in bandwidth. Do not take a short-cut, always check if the destination address is known to belong to a peer. As a side-effect this also removes any behavioral differences between one, and two or more connected peers.

Like any IPv6 capable device, 6LNs can have multiple addresses assigned using SLAAC and made known through neighbour advertisements. After checking the destination address against all peers link-local addresses, consult the neighbour cache for additional known addresses. RFC7668 defines the scope of Neighbor Advertisements in Section 3.2.3: 1. "A Bluetooth LE 6LN MUST NOT register its link-local address" 2. "A Bluetooth LE 6LN MUST register its non-link-local addresses with the 6LBR by sending Neighbor Solicitation (NS) messages ..." Due to these constranits both the link-local addresses tracked in the list of 6lowpan peers, and the neighbour cache have to be used when identifying the 6lowpan peer for a destination address.

Handle overlooked case where the target address is assigned to a peer and neither route nor gateway exist. For one peer, no checks are performed to see if it is meant to receive packets for a given address. As soon as there is a second peer however, checks are performed to deal with routes and gateways for handling complex setups with multiple hops to a target address. This logic assumed that no route and no gateway imply that the destination address can not be reached, which is false in case of a direct peer.

Problem: The Linux Bluetooth stack yields complete control over the BLE connection interval to the remote device. The Linux Bluetooth stack provides access to the BLE connection interval min and max values through /sys/kernel/debug/bluetooth/hci0/ conn_min_interval and /sys/kernel/debug/bluetooth/hci0/conn_max_interval. These values are used for initial BLE connections, but the remote device has the ability to request a connection parameter update. In the event that the remote side requests to change the connection interval, the Linux kernel currently only validates that the desired value is within the acceptable range in the Bluetooth specification (6 - 3200, corresponding to 7.5ms - 4000ms). There is currently no validation that the desired value requested by the remote device is within the min/max limits specified in the conn_min_interval/conn_max_interval configurations. This essentially leads to Linux yielding complete control over the connection interval to the remote device. The proposed patch adds a verification step to the connection parameter update mechanism, ensuring that the desired value is within the min/max bounds of the current connection. If the desired value is outside of the current connection min/max values, then the connection parameter update request is rejected and the negative response is returned to the remote device. Recall that the initial connection is established using the local conn_min_interval/conn_max_interval values, so this allows the Linux administrator to retain control over the BLE connection interval. The one downside that I see is that the current default Linux values for conn_min_interval and conn_max_interval typically correspond to 30ms and 50ms respectively. If this change were accepted, then it is feasible that some devices would no longer be able to negotiate to their desired connection interval values. This might be remedied by setting the default Linux conn_min_interval and conn_max_interval values to the widest supported range (6 - 3200 / 7.5ms - 4000ms). This could lead to the same behavior as the current implementation, where the remote device could request to change the connection interval value to any value that is permitted by the Bluetooth specification, and Linux would accept the desired value.

Because of both sides doing L2CAP disconnection at the same time, it was possible to receive L2CAP Disconnection Response with CID that was already freed. That caused problems if CID was already reused and L2CAP Connection Request with same CID was sent out. Before this patch kernel deleted channel context regardless of the state of the channel. Example where leftover Disconnection Response (frame #402) causes local device to delete L2CAP channel which was not yet connected. This in turn confuses remote device's stack because same CID is re-used without properly disconnecting.

This change is similar to commit a1616a5a ("Bluetooth: hidp: fix buffer overflow") but for the compat ioctl. We take a string from the user and forgot to ensure that it's NUL terminated. I have also changed the strncpy() in to strscpy() in hidp_setup_hid(). The difference is the strncpy() doesn't necessarily NUL terminate the destination string. Either change would fix the problem but it's nice to take a belt and suspenders approach and do both.

Not every platform has the pinctrl device integrates the GPIO the function such as MT7621 whose pinctrl and GPIO are separate hardware so the driver adds additional boot-gpios to let the MT766[3,8]U can enter the proper boot mode by gpiod for such platform.

QCA BTSOC NVM is a customized firmware file and different vendors may want to have different BTSOC configuration (e.g. Configure SCO over PCM or I2S, Setting Tx power, etc.) via this file.

For the Marvell HCI UART we have to upload two firmware files. The first one is only for switching the baudrate of the device to a higher baudrate. After the baudrate switching firmware has been uploaded the device waits for a final ack (0x5a) before actually switching the baudrate. To send this final ack with the old baudrate give the hci ldisc workqueue a chance to run before switching the baudrate. Without this the final ack will never be received by the device and firmware upload fails. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Because we don't care if debugfs works or not, this trickles back a bit so we can clean things up by making some functions return void instead of an error value that is never going to fail.
