Update the size-xxx-member tags to point to another field in the struct
that should be used for the length in that field. Fix NSEC3/HIP and TSIG
to use to this and generate the correct pack/unpack functions for them.
Remove IPSECKEY from the lib and handle it as an unknown record - it is
such a horrible RR, needed kludges before - now just handle it as an
unknown RR.
All types now use generated pack and unpack functions. The blacklist is
removed.
Remove the use of reflection when packing and unpacking, instead
generate all the pack and unpack functions using msg_generate.
This will generate zmsg.go which in turn calls the helper functions from
msg_helper.go.
This increases the speed by about ~30% while cutting back on memory
usage. Not all RRs are using it, but that will be rectified in upcoming
PR.
Most of the speed increase is in the header/question section parsing.
These functions *are* not generated, but straight forward enough. The
implementation can be found in msg.go.
The new code has been fuzzed by go-fuzz, which turned up some issues.
All files that started with 'z', and not autogenerated were renamed,
i.e. zscan.go is now scan.go.
Reflection is still used, in subsequent PRs it will be removed entirely.
IPSECKEY is kinda strange because it has a type selector which tells
what type a later rdata field has. The type can be a domainname, address
or v6 address. You sort of wish Go would have a union type for this, but
alas.
Currently this is implemented as:
GatewayA net.IP `dns:"a"`
GatewayAAAA net.IP `dns:"aaaa"`
GatewayName string `dns:"domain-name"`
In the IPSECKEY. Only one of these is active at any one time. When
parsing/packing and unpacking the value of GatewayType is checked
to see what to do.
Parsing from strings is also implemented properly and tested. The Unpack
function still needs work.
Some records are copies from others: DNSKEY, CDNSKEY and KEY are
identical. DS, CDS and DLV are too and even RRSIG and SIG.
The parsing functions and the definition can all be used for parsing
all these identical types.
