| | | | | | | | | | | | | | | | | | | | | | | | | The code ignored the I2C_M_RD flag on I2C messages. Instead it assumed an i2c transaction with a single message must be a write operation and a transaction with two messages would be a read operation. Though this works for the driver code, it leads to problems once the i2c device is exposed to code not knowing this convention. For example, I did "insmod i2c-dev" and issued read requests from userspace, which were translated into write requests and destroyed the EEPROM of my device. So, just check and respect the I2C_M_READ flag, which indicates a read when set on a message. If it is absent, it is a write message. Incidentally, changing from the case statement to a while loop allows the code to lift the limitation to two i2c messages per transaction. There are 4 more *_i2c_transfer functions affected by the same behaviour and limitation that should be fixed in the same way.

* media: dw2102: Fix null-ptr-deref in dw2102_i2c_transfer()Zhang Shurong2023-07-191-0/+24
| | | | | | | | | | | | | | | In dw2102_i2c_transfer, msg is controlled by user. When msg[i].buf is null and msg[i].len is zero, former checks on msg[i].buf would be passed. Malicious data finally reach dw2102_i2c_transfer. If accessing msg[i].buf[0] without sanity check, null ptr deref would happen. We add check on msg[i].len to prevent crash.

* media: dw2102: return -EIO instead of -1 for mac address read errorsMauro Carvalho Chehab2023-05-141-3/+3
| | | | | | | | | The dvb-usb core function only checks if the returned value is zero, so it doesn't actually matter the error code. Still, returning -1 as an error condition is something that we don't do upstream. So, change the logic to return -EIO in case of I2C transfer failures.

Both were due to the use of buffers on the stack as parameters to dvb_usb_generic_rw() and the resulting attempt to do DMA with them. The device was non-functional as a result. So, switch this driver over to use a buffer within the device state structure, as has been done with other DVB-USB drivers. Tested with TechnoTrend TT-connect S2-4600.
