No more llarp_buffer_t here!
(I was tracking down a segfault which led me in here and it was easier
to rewrite this to use bt_dict_{consumer,producer} than to decipher all
the cursed llarp_buffer_t and bencode callback nest).
We have basically this same bit of code in tons of places; consolidate
it into llarp::util::slurp_file/llarp::util::dump_file.
Also renames all the extra junk that crept into llarp/util/fs.hpp out of
there into llarp/util/file.hpp instead.
This is not likely to be usable to many people, and people who it *is*
useful for are knowledgeable enough to modify it themselves. Most users
get no use at all and it most likely just confuses them instead.
- ANDROID_NDK_ROOT must be set in env
- cmake should be setting `-DANDROID_API=23`
- specify the correct android API via a define when building openssl; it
has to be in CPPFLAGS (not CFLAGS) because otherwise openssl's
configure script doesn't notice and overrides our define with the
latest API version.
- openssl configure puts $(ANDROID_NDK_ROOT) in the makefile, so we have
to be sure that we put it in the environment for the build command,
too.
- Split up mac.sh into a configure + build scripts (like Windows).
- Don't attempt to build the 'package' target in CI: apparently you have
to have a logged in user at the GUI in order to build a .dmg because
being obtuse is the Apple way.
- Upload the raw Lokinet unsigned app in a .tar.xz, rather than dmg,
because of the above.
- make mac.sh respect JOBS (pun not intended (but still good))
- ReconfigureDNS wasn't returning the old servers; made it void instead
(the Apple code can just store a copy of the original upstream
servers instead).
- Reconfiguring DNS reset the unbound context but didn't replace it, so
a Down()/Up() would crash.
- Simplify Resolver() destructor to just call Down(), and make it final
just so that no one tries to inherit from us (so that calling a
virtual function from the destructor is safe).
- Rename CancelPendingQueries() to Down(); the former cancelled but also
shut down the object, so the name seemed a bit misleading.
- Rename SetInternalState in Resolver_Base to ResetResolver, so that we
aren't conflicting with ResetInternalState from Endpoint (which was a
problem because TunEndpoint inherited from both; it could be resolved
through the different argument type if we removed the default, but
that seems gross).
- Make Resolver use a bare unbound context pointer rather than a
shared_ptr; since Resolver (now) entirely manages it already we don't
need an extra management layer, and it saves a bunch of `.get()`s.
On Apple, the network extension is outside the tunnel routing, so we
cannot have libunbound talk directly to upstream (it would leak DNS when
exit mode is enabled). Instead unbound *always* talks to a localhost
port where we have a "dns trampoline" that takes UDP packets and shoves
them through the tunnel.
We were doing that already, but recent changes here were overwriting the
libunbound settings with.
This also moves the upstream DNS configuration part of `Up()` into its
own method.
We don't have a resolver on macos, so we were running through this loop
with fails == 0 == m_Impls.size() and throwing, crashing the process.
Early return to avoid the failure and fix macos crash.
Apple supports anything here that Clang supports and should have them
set the same as everywhere else.
Most importantly this gives apple the -Wno-deprecated-declarations flag
which has been driving me nuts on macos.
This also version-gates the -Wno-deprecated-declarations so that it
will turn on again when we bump the version beyond .10.
We were requiring `->Next` be true, which means we skipped the last (and
often only) entry of the linked lists and so never properly found the
gateway.
- 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).
