Fedora networking is done with the following components:
- Kernel
- GLIBC
- NetworkManager
- ISC DHCP
Networking concepts and configuration
- Ethernet
- Addressing
- Routing
- Bridging
- Bonding / Teaming
- TCP, UDP and ICMP NAT
- Traffic control
- Tunneling
- Domain name system
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
- IPv4:
getaddrinfo("127.0.0.1", ...)fail with some AI_ADDRCONFIG configurations - IPv6: Fedora 808147 -
getaddrinfo("::1", ...)fails with some configurations of AI_ADDRCONFIG - IPv6:
getaddrinfo("fe80::1234:56ff:fe78:90%eth0", ...)also fails as above - IPv6: GLIBC's nsswitch doesn't support overriding
getaddrinfowhich is requred to resolve link-local IPv6 addresses - DNS:
getaddrinfodoesn't support SRV records
dhclient
- Fixed:
dhclientfails with large values of dhcp-renawal-time, notably the infinity (0xffffffff) value - People say that dhclient exchange is slow, especially on wireless (I can't reproduce)
Avahi
- Avahi's nss-mdns returns link-local IPv6 addresses without scope_id and applications fail to connect
- Avahi's IPv6 support is disabled by default (this has been resolved in the past)
NetworkManager
- Various bugs in NetworkManager
Testing tools
- ping doesn't support IPv6 (you have to use ping6)
