![]() Allow ioctl(PTP_SYS_OFFSET_EXTENDED*) to select CLOCK_AUX clock ids for generating the pre and post hardware readout timestamps. Aside of adding these clocks to the clock ID validation, this also requires to check the timestamp to be valid, i.e. the seconds value being greater than or equal zero. This is necessary because AUX clocks can be asynchronously enabled or disabled, so there is no way to validate the availability upfront. The same could have been achieved by handing the return value of ktime_get_aux_ts64() all the way down to the IOCTL call site, but that'd require to modify all existing ptp::gettimex64() callbacks and their inner call chains. The timestamp check achieves the same with less churn and less complicated code all over the place.
