Subject: [PATCH] ppp: don't start IPv6 configuration on the device
|
|
|
c48088 |
|
|
|
c48088 |
If IPV6CP terminates before IPCP, pppd enters the RUNNING phase and we
|
|
|
c48088 |
start IP configuration without having an IP interface set, which
|
|
|
c48088 |
triggers assertions. Instead, reimplement stage3_ip6_config_start to
|
|
|
c48088 |
be a no-op. Note that IPv6 configuration on PPP devices has never been
|
|
|
c48088 |
supported by NM.
|
|
|
c48088 |
|
|
|
c48088 |
This is a simpler version of upstream commit dd98ada33f33 ("ppp:
|
|
|
c48088 |
introduce SetIfindex pppd plugin D-Bus method") that doesn't require
|
|
|
c48088 |
changing the internal plugin API.
