Regression #14163

Running ``ifconfig`` logs a high volume of netlink debug messages (``genl_handle_message``) on dev snapshots
100%
Description
System log is being spammed with kernel messages. CE 2.7.0.a.20230322.0600. It only appears to happen when the Dashboard is accessed, spamming stops when other configuration webpages are selected.

Hi, I think this is related: https://redmine.pfsense.org/issues/14139 CARP do have problems in the last few builds, they are not just spam messages. BR, Robert

As Christian said, these logs will go away with the next upstream merge.
They are harmless and can safely be ignored. If they bug you setting the `net.netlink.debug.nl_generic_debug_level` sysctl to 7 will make them go away. That's functionally equivalent to the upstream 'fix' for this (in quotes, because this is just an overly verbose log, not an actual problem).
As for issue 14139, the reason those logs turn up there is because carp configuration now uses netlink, which triggers these logs. The problem there is not caused by these logs.

For the record, this appears to be triggered by running ifconfig. So any page or action that ends up using ifconfig will trigger the messages. That makes it simple to test even without hitting the GUI.
After setting sysctl net.netlink.debug.nl_generic_debug_level=7 the messages no longer appear when running ifconfig manually or from the GUI (dashboard, interface status page, etc.).

- Status changed from Feedback to Resolved
The errors when running ifconfig and some others are gone, but there are still some others I see here and there that may be in a different area. I'll open a new issue for those messages on 23.09.
