Networking

IPv6

Fedora IPv6 networking is done with the following components:

• Kernel
• GLIBC
• NetworkManager
• ISC DHCP

Networking bugs

Only platform bugs that can influence various application and/or the overall behavior of the system belong here.

Mobile Broadband

• Gnome 667488 - Mobile Broadband must be re-enabled after every boot or resume, and after a lost connection.
• Fedora 659228 - Fails to auto-connect to registered 3G network

IPv4

• ISC dhclient fails with large values of dhcp-renawal-time, notably the infinity (0xffffffff) value
• getaddrinfo("127.0.0.1", service, &hints, &res) fail with some AI_ADDRCONFIG configurations

IPv6

• Fedora 808147 - getaddrinfo("::1") now fails on an otherwise-ipv4-only system
• Fedora 719178 - Applications can't connect to IPv6 link-local addresses learned through nss-mdns and Avahi
• Fedora 821127 - Avahi's IPv6 support is disabled by default
• Various bugs in NetworkManager's IPv6 support
• GLIBC's nsswitch doesn't support getaddrinfo() override and plugins cannot supply scope_id for link-local IPv6 addresses
