2019-01-19dhcpv4: build more packets with modifiersChristopher Koch
Also drop unnecessary return value of Modifier.
2019-01-15dhcpv4: conform to RFC 2131 with respect to options.Christopher Koch
Removes AddOption and GetOption. RFC 2131 specifies that options may only appear once (Section 4.1). If an option does appear more than once, its byte values must be concatenated. RFC 3396 further specifies that to send options longer than 255 bytes, one option may be split into multiple option codes, which must be concatenated back together by the receiver. Both of these are concerned with the byte representation of options. Fact is, based on both RFCs one can say that an option may only appear once, but may be composed of multiple values. Because an option may appear only once logically in any case, we remove the AddOption and GetOption functions and leave only UpdateOption and GetOneOption. Also remove all additions & checks of the End option - the marshaling and unmarshaling code is exclusively responsible for that now.
2019-01-14iana: rename HwTypeType to HWType, add package comment.Christopher Koch
2019-01-11dhcpv4: simplify marshaling options to binary.Christopher Koch
- Consolidate writing the option code and length to Options.Marshal rather than doing it in each individual option. - Use uio in marshaling code.
2019-01-10dhcpv4: remote OptionGetter interface in favor of Options type.Christopher Koch
2019-01-10dhcpv4: simplify option parsing.Christopher Koch
option's codes and lengths were being parsed twice: once in ParseOption and once in each option type's Parse implementation. Consolidate such that it only happens once. Additionally, only pass data to options that they should parse -- we know the length before the Parse function is called, so the option only gets to see the data it needs to see. Also, use uio.Lexer to simplify parsing code in general. Easier to read and reason about.

2018-07-29Add some helper tools for testsSean Karlage
Adds new `OptionGetter` interface that helps when asserting that certain packets/vendor-specific opts contain specific options.

2018-07-29DHCPv4: Refactor methods for easier testingSean Karlage
This refactors the input parameters for construction DISCOVER/INFORM* packets so that it's easier to write unit tests for DHCPv4 and BSDP methods. It also adds a bunch of unit tests for both packages and rounds out their test coverage.

2018-05-11add dhcpv4.GetOption and dhcpv4.GetSingleOption methods (#63)Brandon Bennett
GetOption and GetOneOption are convenience methods for getting a DHCPv4 option from its Option Code. GetOption returns a list of options that match since the DHCP RFC allows for an option to be present multiple times with its values appended together. (Note: I am not sure I've ever seen this done and it's not clear if how option parsing would work for more complex values. Is appending done at the byte level? ) GetOneOption will return the first found option that matches a code.
