#9594 new bug
[net_server] IPv6 Link Local prevents proper interface deletion
Reported by: | diver | Owned by: | kallisti5 |
---|---|---|---|
Priority: | normal | Milestone: | R1.1 |
Component: | Servers/net_server | Version: | R1/Development |
Keywords: | Cc: | shade | |
Blocked By: | Blocking: | #11276 | |
Platform: | All |
Description
This is hrev45432.
ifconfig del /dev/net/ipro1000/0
deletes the interface from ifconfig, but leaves it in net_device_interfaces list. So if one tries to bring back the interface he will get an error:
ifconfig /dev/net/ipro1000/0 up ifconfig: Couldn't add interface: General system error
Removing /system/add-ons/kernel/network/protocols/ipv6 module or commenting out _ConfigureIPv6LinkLocal fixes it.

Deleting the ipv4 and ipv6 address from the interface prior to deleting it itself doesn't help.

I'm thinking of disabling the local link stuff.. our v6 stack just isn't ready yet. i'm even seeing a local link route with a prefix of -2147454933 in route.

I disabled the link local address in hrev45736 for now. Since we lack v6 address scope, it seems to cause more problems than solve at the moment.

Note that ::/-2147454933 loop, host local
is still there in hrev45736.

Replying to diver:
Note that
::/-2147454933 loop, host local
is still there in hrev45736.
The main reason I decided to disable it. If we can't seem to get the loopback correct... the local link up is a little early :)
I have native IPv6 on my home network again, so I'm going to see if I can figure out whats going on here.
