Subject: [PATCH v4 0/1] net: core: prevent NULL deref in generic_hwtstamp_ioctl_lower()
Date: Wed, 12 Nov 2025 01:36:51 +0800 [thread overview]
Message-ID: <20251111173652.749159-1-r772577952@gmail.com> (raw)
In-Reply-To: <20251103171557.3c5123cc@kernel.org>
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
