Re: [PATCH net-next v2 1/3] rtnetlink: add AF_PACKET multicast dumps

Could the changelog drop or reword that claim?

Okay, I'll drop the claim in v4.

This isn't a bug introduced by this patch, but can this copy expose

uninitialized bytes from ha->addr?

Not related to this patch, will send a follow up.

Can this positional resume cursor silently skip dev->mc entries?

In theory yes, but this follows the existing dumps: there is no
generation counter for dev->mc, and in_dev_dump_ifmcaddr() has the
same window. I'd rather keep it consistent than add a counter just
for this one. If the issue is really worth fixing, I will send a
follow up to fix both places.
