To avoid buffer overflow while reading a corrupted or possibly modified port file we validate the length of each part of the port record to ensure it doesn't exceed the length of the destination buffer. https://bugzilla.kernel.org/show_bug.cgi?id=69931Signed-off-by:

The trigger sources were already validataed in the (*do_cmdtest) before the (*do_cmd) is called. Remove the unnecessary checks in pcl816_ai_cmd(). Signed-off-by:

The trigger sources were already validataed in the (*do_cmdtest) before the (*do_cmd) is called. Refactor the code in das800_ai_do_cmd() to use if/else instead of the switch since the default cases can never be reached. Signed-off-by:

This driver has a (*do_cmdtest) function for analog input async command support but the (*do_cmd) function just returns -EINVAL. Remove the incomplete async command support. Signed-off-by:

Currently the (*do_cmdtest) indicates that TRIG_TIMER is a valid scan_begin_src but later this source is tested as -EINVAL. To simplify the code a bit just remove the TRIG_TIMER source. Signed-off-by:

Remove the unnecessary check of 'cmd->chanlist_len > 0'. The (*do_cmdtest) already validated this before the (*do_cmd) was called. Signed-off-by:

It's not necessary to clear the returned data pointer when an (*insn_read) times out. For aesthetics, remove all of these in the drivers. Signed-off-by:

Use comedi_timeout() to wait for the analog input settle and end-of- conversion. These tests use different registers but the same bit so the register is passed as the 'context'. The same test is used in dmm32at_ai_cmd() but the 'insn' is not available. This is ok since the test function, and comedi_timeout() don't use it. Use comedi_timout() to wait for the analog output end-of-conversion. Signed-off-by:

Use comedi_timeout() to wait for the analog input end-of-conversion. Combine the logic for the pcl812 and acl812 end-of-conversion in the helper function to simplify the driver. Signed-off-by:

Use comedi_timeout() to wait for the analog input pipe full, scanning, amd end-of-conversion status. The status to check it passed as the 'context' to comedi_timeout(). Use comedi_timeout() to wait for the analog output end-of-conversion. This also fixes a possible bug where invalid data is returned for the analog input read if the conversion did not complete, The analog output has a similar possible bug where the cached readback value is incorrect if the conversion times out.

The wait_for() macro in this driver is a bit nasty. It effects control flow which according to the CodingStyle is a _very_ bad idea. The mux_busy() and ad_done() macros are also bad since they rely on a local variable having a specific name. Remove these macros and use comedi_timeout() to wait for the analog input mux busy completion and end-of-conversion. Both of these are detected by reading the same register and testing different bits. Pass the bits to test as the 'context' to the callback function. The dt282x_ai_cmd() function also checks for the mux busy completion. The 'insn' is not available here but passing NULL is safe because nothing uses it. Signed-off-by:

Use comedi_timeout() to wait for the analog input end-of-conversion. This prevents a deadlock condition that could occur by providing a timeout in case the end-of-conversion does not happen. Signed-off-by:

Use comedi_timeout() to wait for the analog input and output end-of- conversion. Use break to exit the loop when a timeout occurs during the analog input read so that common code can be used to disable the device. Signed-off-by:
