[ipv6] Create routing table based on IPv6 settings

2016-07-20T12:02:44+00:00

Use the IPv6 settings to construct the routing table, in a matter analogous to the construction of the IPv4 routing table. This allows for manual assignment of IPv6 addresses via e.g. set net0/ip6 2001:ba8:0:1d4::6950:5845 set net0/len6 64 set net0/gateway6 fe80::226:bff:fedd:d3c0 The prefix length ("len6") may be omitted, in which case a default prefix length of 64 will be assumed. Multiple IPv6 addresses may be assigned manually by implicitly creating child settings blocks. For example: set net0/ip6 2001:ba8:0:1d4::6950:5845 set net0.ula/ip6 fda4:2496:e992::6950:5845 Signed-off-by: Michael Brown

[ipv6] Match user expectations for IPv6 settings priorities

2016-07-19T16:07:53+00:00

A reasonable user expectation is that ${net0/ip6} should show the "highest-priority" of the IPv6 addresses, even when multiple IPv6 addresses are active. The expected order of priority is likely to be manually-assigned addresses first, then stateful DHCPv6 addresses, then SLAAC addresses, and lastly link-local addresses. Using ${priority} to enforce an ordering is undesirable since that would affect the priority assigned to each of the net blocks as a whole, so use the sibling ordering capability instead.

[ipv6] Expose IPv6 settings acquired through NDP

2016-07-18T23:13:00+00:00

Expose the IPv6 address (or prefix) as ${ip6}, the prefix length as ${len6}, and the router address as ${gateway6}. Originally-implemented-by: Hannes Reinecke Originally-implemented-by: Marin Hannache Signed-off-by: Michael Brown

[ipv6] Perform SLAAC only during autoconfiguration

2016-07-15T14:58:47+00:00

We currently perform IPv6 stateless address autoconfiguration (SLAAC) in response to any router advertisement with the relevant flags set. This can result in the local IPv6 source address changing midway through a TCP connection, since our connections bind only to a local port number and do not store a local network address. In addition, this behaviour for SLAAC is inconsistent with that for DHCPv4 and stateful DHCPv6, both of which will be performed only as a result of an explicit autoconfiguration action (e.g. via the default autoboot sequence, or the "ifconf" command). Fix by ignoring router advertisements arriving outside the context of an ongoing autoconfiguration attempt. Signed-off-by: Michael Brown

[ipv6] Do not set sin6_scope_id on source address

2014-05-23T13:11:17+00:00

The transmitting network device is specified via the destination address, not the source address. There is no reason to set sin6_scope_id on the source address. Signed-off-by: Michael Brown

[dns] Support DNS search lists

2014-02-05T14:56:49+00:00

Update the DNS resolver to support DNS search lists (as provided by DHCP option 119, DHCPv6 option 24, or NDP option 31). Add validation code to ensure that parsing of DNS packets does not overrun the input, get stuck in infinite loops, or (worse) write beyond the end of allocated buffers. Signed-off-by: Michael Brown
