Subject: Re: [PATCH v2] netlink: fixup regression in RTM_GETADDR

Date: Mon, 31 Dec 2018 02:10:58 +0000

> From: Arthur Gautier <>
> This commit fixes a regression in AF_INET/RTM_GETADDR and
> Before this commit, the kernel would stop dumping addresses once the first
> skb was full and end the stream with NLMSG_DONE(-EMSGSIZE). The error
> shouldn't be sent back to netlink_dump so the callback is kept alive. The
> userspace is expected to call back with a new empty skb.
> Changes from V1:
>  - The error is not handled in netlink_dump anymore but rather in
>    inet_dump_ifaddr and inet6_dump_addr directly as suggested by
>    David Ahern.
> Fixes: d7e38611b81e ("net/ipv4: Put target net when address dump fails due to bad attributes")
> Fixes: 242afaa6968c ("net/ipv6: Put target net when address dump fails due to bad attributes")
