2019-07-06Bluetooth: Check state in l2cap_disconnect_rspMatias Karhumaa1-0/+6
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.

2019-07-06Bluetooth: hidp: NUL terminate a string in the compat ioctlDan Carpenter2-1/+2
This change is similar to commit a1616a5ac99e ("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.

2019-07-06Bluetooth: hci_mrvl: Wait for final ack before switching baudrateSascha Hauer1-0/+3
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>

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.

The event is not processed in the context of the baudrate change and is later interpreted as response to the firmware download command (which is also a vendor command), but the driver detects that the event doesn't have the expected amount of associated data. More details: For the WCN3990 the vendor command for a baudrate change isn't sent as synchronous HCI command, because the controller sends the corresponding vendor event with the new baudrate. The event is received and decoded after the baudrate change of the host port. Identify the 'unused' event when it is received and don't add it to the queue of RX frames.

Add support for transmit side kernel-TLS acceleration. Offload the crypto encryption to HW. Per TLS connection: - Use a separate TIS to maintain the HW context. - Use a separate encryption key. - Maintain static and progress HW contexts by posting the proper WQEs at creation time, or upon resync. - Use a special DUMP opcode to replay the previous frags and sync the HW context. To make sure the SQ is able to serve an xmit request, increase SQ stop room to cover: - static params WQE, - progress params WQE, and - resync DUMP per frag.

When ctrl->tisn field exists, this indicates an operation (HW offload) on the TCP payload. For such WQEs, inline the headers up to L4. This is in preparation for kTLS HW offload support, added in a downstream patch.

Always contain all acceleration functions declarations in 'accel' files, independent to the flags setting. For this, introduce new flags CONFIG_FPGA_{IPSEC/TLS} and use stubs where needed. This obsoletes the need for stubs in 'fpga' files. Remove them. Also use the new flags in Makefile, to decide whether to compile TLS-specific or IPSEC-specific objects, or not.

2019-07-05net: netsec: Sync dma for device on buffer allocationIlias Apalodimas1-0/+5
Quoting Arnd, We have to do a sync_single_for_device /somewhere/ before the buffer is given to the device. On a non-cache-coherent machine with a write-back cache, there may be dirty cache lines that get written back after the device DMA's data into it (e.g. from a previous memset from before the buffer got freed), so you absolutely need to flush any dirty cache lines on it first. Since the coherency is configurable in this device make sure we cover all configurations by explicitly syncing the allocated buffer for the device before refilling it's descriptors Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Signed-off-by: David S.
