Thanks ghedo
* Definitions
* TypeHTTPSSVC
* Generated
and isDuplicate
* Goodbye lenient functions
Now private key=value pairs have to be defined as structs too. They are no longer automatically named as KeyNNNNN
* Encode/decode
* Experimental svc
* Read method
* Implement some of the methods, use trick...
to report where the error is while reading it. This should be applied to EDNS too. Todo: Find if case can only contain e := new(SVC_ALPN) and rest moved out
Also fix two compile errors
* Add SVC_LOCAL methods, reorder, remove alpn value, bugs
* Errors
* Alpn, make it build
* Correct testsuite
* Fully implement parser
Change from keeping a state variable to reading in one iteration until the key=value pair is fully consumed
* Simplify and document
EDNS should be simplified too
* Attempt to fix fuzzer
And Alpn bug
* A bug and change type values to match @ghedo's implementation
* IP bug
Also there are two ip duplicating patterns, one with copy, one with append. Maybe change it to be consistent.
* Check for strictly increasing keys as required
* Don't panic on invalid alpn
* Redundant check, don't modify original array
* Size calculation
* Fix the fuzzer, match the style
* 65535 is reserved too, don't delay errors
* Check keyNNN, check for aliasform having values
* IPvNHint is an array
* Fix ipvNHint
* Rename everything
* Unrecognized keys according to the updated specification
* Skip zero-length structs in generators. Fix CI
* Doc cleanup
* Off by one
* Add parse tests
* Check if private key doesn't collide with known key, invalid tests
* Disallow IPv4 as IPv6. More tests.
Related #1107
* Style fixes
* More consistency, more tests
* 🐛 Deep copy as in the documentation
a := make([]net.IP, 1)
a[0] = net.ParseIP("1.1.1.1").To4()
b := append(make([]net.IP, 0, 1), a...)
b[0] = net.ParseIP("3.1.1.1").To4()
fmt.Println(a[0][0])
* Make tests readable
* Move valid parse tests to different file
* 🐛 One of previous commits not fully committed
* Test binary single value encoding/decoding and full encode/decode
* Add worst-case grows to builders, 🐛 Wrong visible character range, redundant tests
* Testing improvements
And don't convert to IPv4 twice
* Doc update only
* Document worst case allocations
and ipv6 can be at most of length 39, not 40
* Redundant IP copy, consistent IPv6 behavior, fix deep copy
* isDuplicate for SVCB
* Optimizations
* echoconfig
* Svc => SVCB
* Fix CI
* Regenerate after REBASE (2)
Rebased twice on 15th and 20th May
* Rename svc, use escapeByte.
* Fix parsing whitespaces between quotes, rename ECHOHOConfig
* resolve
Remove svcbFieldLen
Use reverseInt
Uppercase SVCB
Rename key_value
"invalid" => bad

* Cross reference IsDomainName and packDomainName
* Correct IsDomainName max length comment
* Use an interface method for unpacking records
* Eliminate err var declaration from unpack functions
* Remove pointless r.Data assignment in PrivateRR.unpack
Sorely missing from this library. Add it. As there is no presentation
format the String method for this type puts a comment in front of it.

* Avoid setting the Rdlength field when packing
The offset of the end of the header is now returned from the RR.pack
method, with the RDLENGTH record field being written in packRR.
To maintain compatability with callers of PackRR who might be relying
on this old behaviour, PackRR will now set rr.Header().Rdlength for
external callers. Care must be taken by callers to ensure this won't
cause a data-race.
* Prevent panic if TestClientLocalAddress fails
This came up during testing of the previous change.
* Change style of overflow check in packRR
* Reduce compression memory use with map[string]uint16
map[string]uint16 uses 25% less memory per-entry than a map[string]int
(16+2)/(16+8) = 0.75. All entries in the compression map are bound by
maxCompressionOffset which is 14-bits and fits within a uint16.
* Add PackMsg benchmark with more RRs
* Add a comment to the compressionMap struct
* Stop compressing names in RT records
Although RFC 1183 allows names in the RT record to be compressed with:
"The concrete encoding is identical to the MX RR."
RFC 3597 specifically prohibits compressing names in any record not
defined in RFC 1035.
* Add comment to RT struct regarding compression
* Add support for TKEY RRs
- make sure Key and Data fields are variable length hex fields
- checkin output from 'go generate'
- add a TKEY specific test to ensure this stays working
* go format changes
* address review comments
* add ability to parse TKEY via string
* handle review comments - change TKEY string output
Implement the CSYNC record.
Fixes#290
Long overdue, lets add this record. Similar in vain as NSEC/NSEC3, we
need to implement len() our selves. Presentation format parsing and
tests are done as well.
This is CoreDNS running with CSYNC support, `dig` doesn't support this
at the moment, so:

1) Refactoring of tlsa.go
- moved routine to create the certificate rdata to its own go module
as this is shared between TLSA and SMIMEA records
2) Added support for creating an SMIMEA domain name
3) Developed in accordance with draft-ietf-dane-smime-12 RFC
Miek,
Submitting for your review. Happy to make any recommended changes or
address omissions.
Lightly tested against our internal DNS service which hosts DANE
SMIMEA records for our email certificates.
Parse tests are added.
When removing the reflection we inadvertely also removed the code for
handling empty salt values in NSEC3 and NSEC3PARAM. These are somewhat
annoying because the text representation is '-', which is not valid hex.
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.
Make the reflection types a black list (these types use (or should use)
the tag 'size-xxx' in their struct definition.s
HIP, IPSECKEY, NSEC3, TSIG
All other types don't use reflection anymore.
* Return a pointer to the header when there is no rdata, this restores old
behavior. The rest of the conversion mostly hangs on getting size-hex
right, but then packStruct and packStructValue and the unpack variant
can be killed.
* Generate pack and unpack for all embedded types as well.
* Fix PrivateRRs, register an unpack function as well, when you register
a new PrivateRR.
* Add the tag octet, nsec, []domains and more to msg_helper.go
Add dns:txt parsing helper to prevent compile errors. This allows
us to generate all unpack/pack function.
Add pack to the RR interface definition and add this method to
PrivateRR.
We still use typeToUnpack to select which types don't use reflection.
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.
