2020-06-20dhcpv4: Fix a panic in parsing of route optionsAnatole Denis
When parsing a route option with a mask size >32, there would be a panic at option_routes.go:47 as user-supplied data is used without verification for a slice bound, causing a read of masksize/8, whic is possibly >4 bytes. Instead reject the invalid route Signed-off-by: Anatole Denis <natolumin@unverle.fr>
2020-06-20dhcpv4: Also write out 0-length optionsAnatole Denis
When there was a 0-length generic option, it would be omitted. Rapid commit (option 80) is a 0-length option with a length tag. There could also be 0-length options in the vendor extensions, and the RFC states that they should be written out: > Any options defined subsequent to this document should contain a > length octet even if the length is fixed or zero. Signed-off-by: Anatole Denis <natolumin@unverle.fr>
2020-06-20dhcpv4: Remove hlen parameter special case in ToBytes()Anatole Denis
There is a special case for when ClientHwAddr is empty, which seems to only apply when creating a packet with New(), which defaults to HWType==Ethernet but doesn't assign the ClientHwAddr field. All the other New*() constructors assign a hardware address and don't use this codepath Remove this special case and instead make New() generate an almost-correct packet in the first place, so that ToBytes() can stay more generic Signed-off-by: Anatole Denis <natolumin@unverle.fr>
2020-06-20dhcpv4: Avoid a panic in ToBytes() with long stringsAnatole Denis
When BootFileName is longer than 128 bytes or ServerHostName is longer than 64 bytes, trying to null-terminate the strings when writing out the packet causes a panic. Since the ToBytes() function cannot return errors, silently truncate the string instead (we do the same with ClientHWAddr if it is longer than 16 bytes for example) Signed-off-by: Anatole Denis <natolumin@unverle.fr>
2020-06-20dhcpv4: Consolidate identical tests into 1Anatole Denis
Those 2 tests did the exact same thing: check that an invalid packet raises an error when parsed. Merge them into the same test, so that we can easily add more test cases to the list Signed-off-by: Anatole Denis <natolumin@unverle.fr>

Each instance of the option is interpreted according to the option codes defined by the vendor identified by the Enterprise Number in that option. Servers and clients MUST NOT send more than one instance of the Vendor-specific Information option with the same Enterprise Number. Signed-off-by: Chris Koch <chrisko@google.com>
