Networking features are nowadays important for virtually all users of Fedora and other linux distributions. Fedora's main network use cases are laptops, desktops, servers and virtualization. Fedora could also be used for routers, becoming part of networking infrastructure.

Notable networking problems

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

Kernel

  • Bridge: Adding first interface after setting MAC address changes the MAC address
  • IPv4: Kernel can't store DHCP lifetime and cannot mark IPv6 addresses dynamic (in the DHCP sense)
  • IPv6: Kernel ignores RA router preference
  • IPv6: Tempaddr cycling breaks TCP connections prematurely
  • IPv6: Kernel doesn't cache RDNSS and DNSSL
  • IPv6: Kernel doesn't provide default route information when defrtr is disabled
  • IPv6: Kernel doesn't provide prefix route information when pinfo is disabled

libnl

  • rtnl_link_bond_add() succeeds when device already exists
  • rtnl_link_bridge_add() and rtnl_link_vlan_add missing

iproute

  • iproute won't distinguish bridges and bonds
  • iproute won't show vlan id

GLIBC

dhclient

Avahi

NetworkManager

Testing tools

  • ping doesn't support IPv6 (you have to use ping6)
  • netstat and ss won't mark non-v6only sockets
