2020-03-05dhcpv6: intro Getters for OptionsChris Koch
Allow the Options type to have getters for each specific options, in order to avoid users having to cast options to their specific type. This commit introduces a getter for exactly one option: the ClientArchType. i.e. users can replace archTypes := msg.GetOneOption(OptionClientArchType).(*OptClientArchType) with archTypes := msg.Options.ArchTypes() Because a few message types and options embed options (normal message, relay message, IANA/IATA option) and each have a restricted set of options that can be used inside them, we'll introduce at least 3 or more Options subtypes: - MessageOptions - RelayOptions - IdentityOptions Perhaps others will join at a later time, such as VendorOptions or AddressOptions for the IAAddress options field.

2019-05-02[dhcpv6] Handle SOLICIT with rapid commit in NewReplyFromMessageAndrea Barberio
NewReplyFromMessage creates a reply from a message. With this patch it can handle Solicit messages with rapid-commit. RFC3315 states that: ``` If the client has included a Rapid Commit option in its Solicit message, the client terminates the waiting process as soon as a Reply message with a Rapid Commit option is received. ``` Signed-off-by: Andrea Barberio <insomniac@slackware.it>
2019-04-24[dhcpv6] Solicit messages derive default IAID from MAC addressAndrea Barberio
IAID must be set by the client. This patch generates the IAID from the MAC address of the interface. To do so, a new WithIAID modifier is added, the interface of NewSolicitWithCID now requires a hwaddr parameter, and NewAdvertiseFromSolicit copies the IA_NA option from the solicit if present.

Add a more generic NewReplyFromMessage to avoid code duplication. This is one step closer towards fixing issue #73. Leave NewReplyFromRequest, NewReplyFromRenew and NewReplyFromRebind for backwards compatibility.

2018-04-20dhcpv6: added modifiers (#41)insomniac
dhcpv6: added modifiers Added support for packet modifiers, i.e. functions that can arbitrarily manipulate a DHCPv6 packet. These modifiers are used by NewMessage, NewSolicitForInterface, NewRequestForAdvertise, and can be used by other packet creation functions. A bunch of sample modifiers have been added under modifiers.go , too. With the introduction of modifiers I also removed some options that should not necessarily be in a standard DHCPv6 message.
