net/iproute2: clarify "waiting for IPv6 addresses" |
| 9 |
|
| 10 |
Per bug 636846, a user thought that "waiting for IPv6 addresses" was |
| 11 |
SLAAC (Stateless Autoconfiguration). In Linux, SLAAC is entirely |
| 12 |
kernel-side, and the waiting is actually for DAD (duplicate address |
| 13 |
detection) on link-local IPv6 addresses. |
| 14 |
|
| 15 |
- Improve the message to include both DAD & tentative. |
| 16 |
- If --verbose is used, print the tentative addresses. |
| 17 |
|
| 18 |
If either of the accept_dad sysctls are set to zero, then the kernel |
| 19 |
should NOT mark any addresses as tentative. |
| 20 |
- net.ipv6.conf.all.accept_dad=0 |
| 21 |
- net.ipv6.conf.$IFACE.accept_dad=0 |
