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.
* bump zmq static dep
* lokimq -> oxenmq
* llarp_nodedb -> llarp::NodeDB
* remove all crufty api parts of NodeDB
* make NodeDB rc selection api not suck
* make path builder api not suck
* propagate all above changes so that unit tests work and it all compiles
* Config file API/comment improvements
API improvements:
=================
Make the config API use position-independent tag parameters (Required,
Default{123}, MultiValue) rather than a sequence of bools with
overloads. For example, instead of:
conf.defineOption<int>("a", "b", false, true, 123, [] { ... });
you now write:
conf.defineOption<int>("a", "b", MultiValue, Default{123}, [] { ... });
The tags are:
- Required
- MultiValue
- Default{value}
plus new abilities (see below):
- Hidden
- RelayOnly
- ClientOnly
- Comment{"line1", "line2", "line3"}
Made option definition more powerful:
=====================================
- `Hidden` allows you to define an option that won't show up in the
generated config file if it isn't set.
- `RelayOnly`/`ClientOnly` sets up an option that is only accepted and
only shows up for relay or client configs. (If neither is specified
the option shows up in both modes).
- `Comment{...}` lets the option comments be specified as part of the
defineOption.
Comment improvements
====================
- Rewrote comments for various options to expand on details.
- Inlined all the comments with the option definitions.
- Several options that were missing comments got comments added.
- Made various options for deprecated and or internal options hidden by
default so that they don't show up in a default config file.
- show the section comment (but not option comments) *after* the
[section] tag instead of before it as it makes more sense that way
(particularly for the [bind] section which has a new long comment to
describe how it works).
Disable profiling by default
============================
We had this weird state where we use and store profiling by default but
never *load* it when starting up. This commit makes us just not use
profiling at all unless explicitly enabled.
Other misc changes:
===================
- change default worker threads to 0 (= num cpus) instead of 1, and fix
it to allow 0.
- Actually apply worker-threads option
- fixed default data-dir value erroneously having quotes around it
- reordered ifname/ifaddr/mapaddr (was previously mapaddr/ifaddr/ifname)
as mapaddr is a sort of specialization of ifaddr and so makes more
sense to come after it (particularly because it now references ifaddr
in its help message).
- removed peer-stats option (since we always require it for relays and
never use it for clients)
- removed router profiles filename option (this doesn't need to be
configurable)
- removed defunct `service-node-seed` option
- Change default logging output file to "" (which means stdout), and
also made "-" work for stdout.
* Router hive compilation fixes
* Comments for SNApp SRV settings in ini file
* Add extra blank line after section comments
* Better deprecated option handling
Allow {client,relay}-only options in {relay,client} configs to be
specified as implicitly deprecated options: they warn, and don't set
anything.
Add an explicit `Deprecated` tag and move deprecated option handling
into definition.cpp.
* Move backwards compat options into section definitions
Keep the "addBackwardsCompatibleConfigOptions" only for options in
sections that no longer exist.
* Fix INI parsing issues & C++17-ify
- don't allow inline comments because it seems they aren't allowed in
ini formats in general, and is going to cause problems if there is a
comment character in a value (e.g. an exit auth string). Additionally
it was breaking on a line such as:
# some comment; see?
because it was treating only `; see?` as the comment and then producing
an error message about the rest of the line being invalid.
- make section parsing stricter: the `[` and `]` have to be at the
beginning at end of the line now (after stripping whitespace).
- Move whitespace stripping to the top since everything in here does it.
- chop off string_view suffix/prefix rather than maintaining position
values
- fix potential infinite loop/segfault when given a line such as `]foo[`
* Make config parsing failure fatal
Load() LogError's and returns false on failure, so we weren't aborting
on config file errors.
* Formatting: allow `{}` for empty functions/structs
Instead of using two lines when empty:
{
}
* Make default dns bind 127.0.0.1 on non-Linux
* Don't show empty section; fix tests
We can conceivably have sections that only make sense for clients or
relays, and so want to completely omit that section if we have no
options for the type of config being generated.
Also fixes missing empty lines between tests.

This replaces all use of std::optional's `opt.value()` with `*opt`
because macOS is great and the ghost of Steve Jobs says that actually
supporting std::optional's value() method is not for chumps before macOS
10.14. So don't use it because Apple is great.
Pretty much all of our use of it actually is done better with operator*
anyway (since operator* doesn't do a check that the optional has a
value).
Also replaced *most* of the `has_value()` calls with direct bool
context, except for one in the config section which looked really
confusing at a glance without a has_value().
This commit reflects changes to clang-format rules. Unfortunately,
these rule changes create a massive change to the codebase, which
causes an apparent rewrite of git history.
Git blame's --ignore-rev flag can be used to ignore this commit when
attempting to `git blame` some code.
This was being used to get at gcc/clang's __builtin_expect, but we don't
really need that: we can just avoid the check entirely when not in debug
mode which should be even faster.
These aren't needed: CMake already knows how to follow #includes and
rebuild when headers change as long as the headers are included
*somewhere*. The extra .cpp files here just require building a bunch of
.cpp files with just header content that we just end up throw away
during linking (since the same things will also be compiled in whatever
other compilation units include the same headers).
This makes PrivateKey store both the key followed by the hash. For
PrivateKeys based on SecretKeys this just means the second half of the
SHA-512 of the seed, and makes a PrivateKey constructed from a SecretKey
give an identical signature to signing directly with sodium.
For derived keys we use a ShortHash of the root key's signing hash
concatenated with the publicly known hash value, so that our derived key
signing hash will be different from the root signing hash and also
different for different derivation parameters.
This also changed one of the asserts in crypto_noop, but upon closer
inspection the copying of the secret key into the signature seems really
wrong, so just changed them to fill with 0s.
The reason things weren't working here is because libsodium does
something completely unintuitive and called the seed the "secret key"
when it isn't, it's the seed.
This adds a new PrivateKey class (alongside the existing SecretKey and
PubKey) that holds just a private key value but no seed -- which we need
to do because there is no way we can get a seed after calculating a
derived keypair.
With these changes, we now generate exactly the same keys and subkeys as
Tor (and a new test case uses values generated in Tor to verify this).
This is incomplete -- the subkey signing code is still not implemented;
it has to be adapted to create a signature from a PrivateKey rather than
a SecretKey which will probably requiring working around/reimplementing
some of what libsodium does for creating a signature since it expects
"secret keys" i.e. the seed.
Success case:
- the path endpoint creates and sends a LR_StatusMessage upon
successful path creation
Failure case:
- an intermediate hop creates and sends a LR_StatusMessage upon
failure to forward the path to the next hop for any reason
Both cases:
- transit hops receive LR_StatusMessages and add a frame
to them reflecting their "status" with respect to that path
- the path creator receives LR_StatusMessages and decrypts/parses
the LR_StatusRecord frames from the path hops. If all is good,
the Path does as it would when receiving a PathConfirmMessage.
If not, the Path marks the new path as failed.
LR_StatusMessage is now used/sent in place of PathConfirmMessage
