Subject: [BISECTED] [4.17.0-rc6] IPv6 link-local address not getting added
Date: Wed, 27 Jun 2018 20:35:15 -0400 [thread overview]
Message-ID: <20180628003515.GD985@oracle.com> (raw)
Hi David,
An IPv6 regression has been introduced in 4.17.0-rc6 by
8308f3f net/ipv6: Add support for specifying metric of connected routes
The regression is that some interfaces on my test machine come
up with link-local addrs but the fe80 prefix is missing.
After this bug, I cannot send any packets to anyone onlink
(including my routers).
Here are the symptoms:
When everything is fine, "ip -6 route|grep eno" shows
2606:b400:400:18c8::/64 dev eno1 proto ra metric 100 pref medium
fe80::5:73ff:fea0:52d dev eno1 proto static metric 100 pref medium
fe80::/64 dev eno1 proto kernel metric 256 pref medium
fe80::/64 dev eno3 proto kernel metric 256 pref medium
fe80::/64 dev eno4 proto kernel metric 256 pref medium
default via fe80::5:73ff:fea0:52d dev eno1 proto static metric 100 pref medium
But after 8308f3f, I only find
# ip -6 route|grep eno
2606:b400:400:18c8::/64 dev eno1 proto ra metric 100 pref medium
fe80::5:73ff:fea0:52d dev eno1 proto static metric 100 pref medium
fe80::/64 dev eno1 proto kernel metric 256 pref medium
default via fe80::5:73ff:fea0:52d dev eno1 proto static metric 100 pref medium
(note that eno2 is not enabled in my config, so its absence is expected)
Please have a look, thanks.
