* llarp::service::NameIsValid was not checking that the tld was .loki, add this check.
* make link layer initial connection timeout 5s not the session activity timeout which happens to be 60 god damn seconds.
All #ifndef guards on headers have been removed, I think,
in favor of #pragma once
Headers are now included as `#include "filename"` if the included file
resides in the same directory as the file including it, or any
subdirectory therein. Otherwise they are included as
`#include <project/top/dir/relative/path/filename>`
The above does not include system/os headers.
* initial relay side lns
* fix typo
* add reserved names and refactor test for dns
* lns name decryption
* all wired up (allegedly)
* refact to use service::EncryptedName for LNS responses to include nonce with ciphertext
* fully rwemove tag_lookup_job
* replace lns cache with DecayingHashTable
* check for lns name validity against the following rules:
* not localhost.loki, loki.loki, or snode.loki
* if it contains no dash then max 32 characters long, not including the .loki tld (and also assuming a leading subdomain has been stripped)
* These are from general DNS requirements, and also enforced in
registrations:
* Must be all [A-Za-z0-9-]. (A-Z will be lower-cased by the RPC call).
* cannot start or end with a -
* max 63 characters long if it does contain a dash
* cannot contain -- in the third and fourth characters unless it starts with xn--
* handle timeout in name lookup job by calling the right handler with std::nullopt
