- We need to pass a flag to get Windows to include gateway info.
- Refactor it to use microsoft's recommended magic default 15000 buffer
size and repeat in a loop a few times until it works. Developers,
developers, developers, developers!
- a `static` is less verbose and otherwise identical to an empty
namespace for a single declaration like this.
- operator== on two optionals already does exactly what the `is_equal`
lambda here is doing.
- formatting
- windivert was being set up *before* DNS is set up, so the DNS port was
nullopt and thus we couldn't properly identify upstream DNS traffic.
- close() doesn't close a socket on Windows, so the socket-bind-close
approach to get a free UDP port wasn't actually closing, and thus
unbound upstream constrained to the given port were completely
failing.
- The unbound thread was accessing the same shared_ptr instance as the
outer code, which isn't thread-safe; changed it to copy a weak_ptr
into the lambda instead.
- Exclude upstream DNS traffic in the filter rather than capturing and
reinjecting it.
The inner lambda here wasn't keeping the `Query` (`this`) alive, so
`src` wasn't valid anymore. This changes it to copy the `src`
shared_ptr into the lambda instead of capturing `this`, and fixes it.
The current code isn't working and gives a 0 (which then fails unbound
initialization). This replaces it by doing a socket+bind to find a free
port then immediately closes (but passes the port we got into unbound).
- Replaces RAII handling of DLLs with global function pointers. (We
don't unload the dll this way, but that seems unnecessary anyway).
- Simplifies code by just needing to call an init function, but not
needing to pass around an object holding the function pointers.
- Adds a templated dll loader that takes the dll and a list of
name/pointer pairs to load the dll and set the pointers in one shot.
ip_header wasn't 20 bytes on windows compilations for some unholy
reason. This restructures it to avoid the template and just use two
different structs for le/be with a condition_t for the ifdef, which
resolves it (and *also* apparently avoids the need for the pack).
Also add a static_assert to check the size.
Also do the same for ipv6.
Cast via an ordinary function pointer rather than a function pointer
reference to avoid the warning.
Also make the pointer in `Func_t` explicit rather than implicit (deduced
into the `Func_t` type) to make it clearer what is going on here.
3.13...3.xx means "minimum is 3.13, but use any new cmake policies
introduced up to 3.xx".
There was, in particular, a policy w.r.t. external project timestamps
causing warnings under 3.24.
Lots of tools struggle with non-default DNS port, so keep a listener on
127.3.2.1:53 (by default).
This required various changes to the config handling to hold a vector
(instead of an optional) of defaults and values, and now allows passing
in an array of defaults instead of just a single default.
It didn't do equality, it did "does the remaining space start with the
argument" (and so the replacement in the previous commit was broken).
This renames it to avoid the confusion and restores to what it was doing
on dev.
errno is only set if read returns < 0 and won't be set to 0 if read
succeeds, so we were bailing here frequently on successful reads
(whenever errno happened to be non-0).
This class is cursed, but also broken under gcc-12. Apply some lipstick
to get it moving again (but we really need to refactor this because it
is a mess).
add jason's suggested changes for artifact upload
use lokinet-ci-nodejs-lts as base image so we can build the installer
update ci pipeline for windows to have building gui toggle-able
by default we will build the gui from this repo, but this allows it to
easily run using a custom gui asset if needed
* wintun vpn platform for windows
* bundle config snippets into nsis installer for exit node, keyfile persisting, reduced hops mode.
* use wintun for vpn platform
* isolate all windows platform specific code into their own compilation units and libraries
* split up internal libraries into more specific components
* rename liblokinet.a target to liblokinet-amalgum.a to elimiate ambiguity with liblokinet.so
* DNS platform for win32
* rename llarp/ev/ev_libuv.{c,h}pp to llarp/ev/libuv.{c,h}pp as the old name was idiotic
* split up net platform into win32 and posix specific compilation units
* rename lokinet_init.c to easter_eggs.cpp as that is what they are for and it does not need to be a c compilation target
* add cmake option STRIP_SYMBOLS for seperating out debug symbols for windows builds
* intercept dns traffic on all interfaces on windows using windivert and feed it into lokinet
* allow specifying a custom yarn binary for building the gui using -DYARN= cmake option
* unset DISPLAY when calling wine because i hate popups
* do not rebuild gui when building for windows
* by setting the magical undocumented env var USE_SYSTEM_7ZA to 'true' we can have the pile of npm bullshit code use our system's local 7z binary instead of the probably not backdoored binary from npm, yes for real. i hate nodejs so god damn much you have no fucking idea
* allow providing a custom gui from a zip file via -DGUI_ZIP_FILE cmake option
we want to be able to have multiple locally bound dns sockets in lokinet so
i restructured most of the dns subsystem in order to make this easier.
specifically, we have a new structure to dns subsystem:
* dns::QueryJob_Base
base type for holding a dns query and response with virtual methods
in charge of sending a reply to whoever requested.
* dns::PacketSource_Base
base type for reading and writing dns messages to and from wherever they came from
* dns::Resolver_Base
base type for filtering and handling of dns messages asynchronously.
* dns::Server
contextualized per endpoint dns object, responsible for all dns related isms.
this change hides all impelementation details of all of the dns components.
adds some more helper functions for parsing dns and dealing with OwnedBuffer.
overall dns becomes less of a pain with this new structure. probably.
