2021-05-28Break circular dependency on u-rootChris Koch
u-root -> dhcp -> u-root is the circular dependency. Which is fine, except we messed up modules in u-root big time. We need to break the circular dep for now. Signed-off-by: Chris Koch <chrisko@google.com>

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.

2019-10-08dhcpv6: Add error checks to message parsersAnatole Denis
There were missing error checks in the Message and RelayMessage parsers, so that truncated headers would be incorrectly accepted as valid messages. For example the single byte "0" (0x30) would be accepted as a valid message, then reserialized to 0x30,0x00,0x00,0x00,0x00 Signed-off-by: Anatole Denis <natolumin@unverle.fr>
2019-10-08dhcpv6: Reject empty messagesAnatole Denis
The uio library doesn't report errors on a per-operation basis, but accumulates them so they can be checked after a batch of operations in a separate Error() function. Unfortunately this makes it easy to forget, thus parse incorrect messages go-fuzz found immediately that an empty message would be parsed without error, and reserialize to a different message (one with some bytes of zeros) Signed-off-by: Anatole Denis <natolumin@unverle.fr>

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.
