I think this fix will be affected at the next release. Is there a predetermined time for the next release. Or Is there any workaround to use UDP source without error at v3.7.9.2.


Best regards

Not sure how this would get leveraged by itself.

But there are likely lots of kernel calls that have parameters that are ignored in certain contexts.  I would be astonished if a general-purpose, long-lived, operating existed without that being the case from time to time.

Easy enough to just remove that option for the UDP case.

I think it's a bit of a security failing of Linux to allow injection of
4 unused bytes into the kernel space from user-space for every locally
opened UDP socket.  I'm not sure how I could exploit it (perhaps coding
a jump instruction to a no-op sled somewhere nearby?),  but I'm not that
