2022-10-01dhcpv4: add test for NewInform() with modifiersDennis Marttinen
`NewInform()` exposes a consumer-facing interface that accepts modifiers, but this functionality is never tested unlike with for example `NewRequest()` and `NewRenew()`. To ensure that modifiers are correctly respected and any future modifications won't break this support, add a modifier test for `NewInform()`. Signed-off-by: Dennis Marttinen <twelho@welho.tech>
2022-10-01dhcpv4: make NewInform() formatting consistent with neighborsDennis Marttinen
This is just a minor readability improvement that makes `NewInform()` consistent with the neighboring functions like `NewRequest()`, `NewReply()`, `NewRelease()` etc. Having the prepended modifiers on the same line helps with separating the modifiers that provided by the function from the modifiers passed in by the consumer of the function. Signed-off-by: Dennis Marttinen <twelho@welho.tech>
2022-10-01dhcpv4: fix require.NotNil() usage in testsDennis Marttinen
Any parameter passed to `require.NotNil()` after the first two will not be tested but instead appended to the message that is printed if the test fails. This means that `lease.ACK` was never tested to not be nil. Signed-off-by: Dennis Marttinen <twelho@welho.tech>

2021-12-13fix: check IP/UDP header size before trying to access itAndrey Smirnov
This should fix the panic we've seen with the malformed packets on the wire. Remaining buffer size should be checked before trying to access the data, otherwise Go might panic on out of bounds slice operation. Signed-off-by: Andrey Smirnov <andrey.smirnov@talos-systems.com>

2021-03-06Pad packets after the 'end' option to be more conformantMarcel Moolenaar
RFC 2131 gives two examples of padding in section 4.1. For both the examples, the 'end' option preceeds the padding with the 'pad' option. These examples relate to overloading pre-defined fields for options, not padding the packet for a minimal size. Older versions of the U-Boot firmware support DHCP, but do not expect the 'pad' option. The firmware logs the following warning for each occurence: *** Unhandled DHCP Option in OFFER/ACK: 0 This warning disappears when the 'end' option preceeds the 'pad' option.
