[Touch-packages] [Bug 1699942] Re: network-manager fails to deprecate addresses
I can reproduce this on kinetic. I get sent a 2a02:908:2812:7d20::/64 prefix via RA with "valid lifetime" and ""preferred lifetime" set to 0, every 3s. Instead of the prefix being deleted from the interface, it's lifetime is set to 1s and then expires every second, causing regular "connection changed" type of errors in Chrome, it looks like this: inet6 2a02:908:2812:7d20::e9eb/128 scope global dynamic noprefixroute valid_lft 42961sec preferred_lft 42961sec inet6 2a02:908:2812:7d20:55e8:17dd:e766:a872/64 scope global deprecated dynamic noprefixroute valid_lft 6603sec preferred_lft 0sec Reconnecting the WiFi gets rid of the /64 prefix. I think my router is broken though, as it does not advertise any valid prefix, so you end up with *only* the /64 prefix until the router receives a new prefix from the ISP or reconfirms it or whatever, but still this is broken regardless. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1699942 Title: network-manager fails to deprecate addresses Status in network-manager package in Ubuntu: New Bug description: network manager does not properly deprecate autoconfigured temporary IP addresses when ValidLifetime for a prefix is 0 in router advertisements.
