2018-01-22scsi: arcmsr: avoid do_gettimeofdayArnd Bergmann1-27/+10
The arcmsr uses its own implementation of time_to_tm(), along with do_gettimeofday() to read the current time. While the algorithm used here is fine in principle, it suffers from two problems: - it assigns the seconds portion of the timeval to a 32-bit unsigned integer that overflows in 2106 even on 64-bit architectures. - do_gettimeofday() returns a time_t that overflows in 2038 on all 32-bit systems. This changes the time retrieval function to ktime_get_real_seconds(), which returns a proper 64-bit value, and replaces the open-coded time_to_tm() algorithm with a call to the safe time64_to_tm(). I checked way all numbers are indexed and found that months are given in range 0..11 while the days are in range 1..31, same as 'struct tm', but the year value that the firmware expects starts in 2000 while 'struct tm' is based on year 1900, so it needs a small adjustment.

2017-12-11scsi: arcmsr: remove redundant check for secs < 0Colin Ian King1-4/+0
The check for secs being less than zero is redundant for two reasons. Firstly, secs is unsigned so the check is always going to be false. Secondly, if secs was signed the proceeding calculation of secs is never going to be negative. Hence we can remove this redundant check and day and secs re-adjustment. Detected by static analysis with smatch: arcmsr_set_iop_datetime() warn: unsigned 'secs' is never less than zero.
