The CEC_MSG_GIVE_DECK_STATUS and CEC_MSG_GIVE_TUNER_DEVICE_STATUS commands both have a status_req argument: ON, OFF, ONCE. If ON or ONCE, then the follower will reply with a STATUS message. Either once or whenever the status changes (status_req == ON). If status_req == OFF, then it will stop sending continuous status updates, but the follower will *not* send a STATUS message in that case. This means that if status_req == OFF, then msg->reply should be 0 as well since no reply is expected in that case. Signed-off-by:

This demod implements an i2c adapter for attached tuner and relays i2c messages from users (dvb adapters / bridge chips). Some of them, such as Friio dvb card using gl861, require each pair of i2c messages for one read to be issued as two separate transactions. This patch adds a configuration option to enable this split. Signed-off-by:

For Friio dvb cards, a distinct I2C algo was provided to support some "long" I2C messages used in relaying tuner I2C via demod. Since the other (generic) i2c algo in this module has been patched to support those messages in a more generic way, this patch replaces and integrates the device-specific i2c algo with the generic one and simplifies the code.

Device I2C adapter is capable of writing and reading large messages. For I2C writes there is 2 methods: simple for max 2 byte messages and usb_control_msg() with payload data for larger I2C messages. Add I2C adapter logic which selects suitable method according to message size. Add also support for plain I2C read. Cc: Akihiro TSUKADA <tskd08@gmail.com> Signed-off-by:

Currently the IR receiver is put into idle mode after each interrupt. However longer IR like NEC can be distributed over multiple interrupts, so putting the IR into idle in the middle of such a message will break decoding. Every IR message has a trailing space of 0xbf (one less than IR_IDE_LEN{0,1} which is programmed to 0xc0). So, set the timeout to that value and rc-core will put the IR receiver into idle mode automatically. Thanks to Jan Pieter van Woerkom <jp@jpvw.nl> for providing the hardware. Signed-off-by: -

Fix multiple cases of out of bounds (OOB) read associated with MCE device receive/input data handling. In reference for the OOB cases below, the incoming/read (byte) data format when the MCE device responds to a command is: { cmd_prefix, subcmd, data0, data1, ... } where cmd_prefix are: MCE_CMD_PORT_SYS MCE_CMD_PORT_IR and subcmd examples are: MCE_RSP_GETPORTSTATUS MCE_RSP_EQIRNUMPORTS ... Response size dynamically depends on cmd_prefix and subcmd. So data0, data1, ... may or may not be present on input. Multiple responses may return in a single receiver buffer. The trigger condition for OOB read is typically random or corrupt input data that fills the mceusb receiver buffer. Case 1: mceusb_handle_command() reads data0 (var hi) and data1 (var lo) regardless of whether the response includes such data. If { cmd_prefix, subcmd } is at the end of the receiver buffer, read past end of buffer occurs. This case was reported by KASAN: slab-out-of-bounds Read in mceusb_dev_recv https://syzkaller.appspot.com/bug?extid=c7fdb6cb36e65f2fe8c9 Fix: In mceusb_handle_command(), change variable hi and lo to pointers, and dereference only when required. Case 2: If response with data is truncated at end of buffer after { cmd_prefix, subcmd }, mceusb_handle_command() reads past end of buffer for data0, data1, ... Fix: In mceusb_process_ir_data(), check response size with remaining buffer size before invoking mceusb_handle_command(). + if (i + ir->rem < buf_len) mceusb_handle_command(ir, &ir->buf_in[i - 1]); Case 3: mceusb_handle_command() handles invalid/bad response such as { 0x??, MCE_RSP_GETPORTSTATUS } of length 2 as a response { MCE_CMD_PORT_SYS, MCE_RSP_GETPORTSTATUS, data0, ... } of length 7. Read OOB occurs for non-existent data0, data1, ... Cause is mceusb_handle_command() does not check cmd_prefix value. Fix: mceusb_handle_command() must test both cmd_prefix and subcmd. Case 4: mceusb_process_ir_data() receiver parser state SUBCMD is possible at start (i=0) of receiver buffer resulting in buffer offset=-1 passed to mceusb_dev_printdata(). Bad offset results in OOB read before start of buffer. [1214218.580308] mceusb 1-1.3:1.0: rx data[0]: 00 80 (length=2) [1214218.580323] mceusb 1-1.3:1.0: Unknown command 0x00 0x80 ...

In effect, discard cmd_prefix at end of receiver buffer. In mceusb_dev_printdata(), abort if buffer offset is out of bounds. Case 5: If response with data is truncated at end of buffer after { cmd_prefix, subcmd }, mceusb_dev_printdata() reads past end of buffer for data0, data1, ... while decoding the response to print out. Fix: In mceusb_dev_printdata(), remove unneeded buffer offset adjustments (var start and var skip) associated with MCE gen1 header. Test for truncated MCE cmd response (compare offset+len with buf_len) and skip decoding of incomplete response. Move IR data tracing to execute before the truncation test.

In downstream driver, there are two frequency tables defined, one for the encoder and one for the decoder: /* Encoders / <972000 490000000 0x55555555>, / 4k UHD @ 30 / <489600 320000000 0x55555555>, / 1080p @ 60 / <244800 150000000 0x55555555>, / 1080p @ 30 / <108000 75000000 0x55555555>, / 720p @ 30 */ /* Decoders / <1944000 490000000 0xffffffff>, / 4k UHD @ 60 / < 972000 320000000 0xffffffff>, / 4k UHD @ 30 / < 489600 150000000 0xffffffff>, / 1080p @ 60 / < 244800 75000000 0xffffffff>; / 1080p @ 30 */ It shows that encoder always needs a higher clock than decoder. In current venus driver, the unified frequency table is aligned with the downstream decoder table which causes performance issues in encoding scenarios. Fix that by aligning frequency table on worst case (encoding). Signed-off-by:

On some board it is possible that the sensor 'powerdown' and or 'reset' pin might be controlled by gpio instead of being tied. To implement we add pm_runtime support which will handle the power up/down sequence when it is available otherwise the sensor will be powered on at module insertion/probe and powered off at module removal. Now originally the driver assumed that the sensor would always stay powered and keep its register setting. We cannot assume this anymore, so every time we "power up" we need to re-program the initial registers configuration first. This was previously done only at probe time.
