[PATCH v4 0/1] net: core: prevent NULL deref in generic_hwtstamp_ioctl_lower()

Posted by Jiaming Zhang 2 months, 3 weeks ago

Hi Jakub,

Sorry for the late response. I have updated the patch, NULL check
is moved from get/set caller to generic_hwstamp_ioctl_lower().

Please let me know if any change is needed :)

v4:
- Move NULL check from generic_hwtstamp_get/set_lower()
  to generic_hwtstamp_ioctl_lower()

v3:
- Add Kory's Reviewed-by tag.

v2:
- Fix typo in comment ("driver" -> "lower driver")

Best Regards,
Jiaming Zhang
