Currently (from a recent PR) we aren't pinging oxend if not active, but
that behaviour ended up being quite wrong because lokinet needs to ping
even when decommissioned or deregistered (when decommissioned we need
the ping to get commissioned again, and if not registered we need the
ping to get past the "lokinet isn't pinging" nag screen to prepare a
registration).
This considerably revises the pinging behaviour:
- We ping oxend *unless* there is a specific error with our connections
(i.e. we *should* be establishing peer connections but don't have any)
- If we do have such an error, we send a new oxend "error" ping to
report the error to oxend and get oxend to hold off on sending uptime
proofs.
Along the way this also changes how we handle the current node state:
instead of just tracking deregistered/decommissioned, we now track three
states:
- LooksRegistered -- which means the SN is known to the network (but not
necessarily active or fully staked)
- LooksFunded -- which means it is known *and* is fully funded, but not
necessarily active
- LooksDecommissioned -- which means it is known, funded, and not
currently active (which implies decommissioned).
The funded (or more precisely, unfunded) state is now tracked in
rc_lookup_handler in a "greenlist" -- i.e. new SNs that are so new (i.e.
"green") that they aren't even fully staked or active yet.
This aligns service node updating logic a bit closer to what happens in
storage server, and should make it a bit more resilient, hopefully
tracking down the (off-Github) reported issue where lokinet sometimes
doesn't see itself as active.
- Initiate a service node list update in the 30s timer lokinet ping
timer (in case we miss a block notify for some reason); although this
is expensive, the next point mitigates it:
- Retrieve the block hash with the SN state update, and feed it back
into the next get_service_nodes call (as "poll_block_hash") so that
oxend just sends back a mostly-empty response when the block hasn't
changed, allowing both oxend and lokinet to skip nearly all of the
work of a service node list update when the block hasn't changed since
the last poll. (This was already partially implemenated--we were
already looking for "unchanged"--but without a block hash to get from
and pass back to oxend we'd never actually get an "unchanged" result).
- Tighten up the service node list handling by moving the "unchanged"
handling into the get_service_nodes response handler: this way the
HandleNewServiceNodeList function is only handling the list but not
the logic as to whether there actually is a new list or not.
Lots and lots of places in the code had broken < operators because they
are returning something like:
foo < other.foo or bar < other.bar;
but this breaks both the strict weak ordering requirements that are
required for the "Compare" requirement for things like
std::map/set/priority_queue.
For example:
a = {.foo=1, .bar=3}
b = {.foo=3, .bar=1}
does not have an ordering over a and b (both `a < b` and `b < a` are
satisfied at the same time).
This needs to be instead something like:
foo < other.foo or (foo == other.foo and bar < other.bar)
but that's a bit clunkier, and it is easier to use std::tie for tuple's
built-in < comparison which does the right thing:
std::tie(foo, bar) < std::tie(other.foo, other.bar)
(Initially I noticed this in SockAddr/sockaddr_in6, but upon further
investigation this extends to the major of multi-field `operator<`'s.)
This fixes it by using std::tie (or something similar) everywhere we are
doing multi-field inequalities.
The non-mac icon was an old version with white foreground and a
completely transparent background, but this looks bad (or invisible)
depending on where you view it. This updates it based on the macos
icon, but with a round white circle background instead of the macos
"squircle" background.
This also replaces the .ico file for the installer with one that we
build during the win32 build rather than a pregenerated one.
Bumps the gui as well to a version with the new icons in place.
If we get back an IPv6 address as the first gateway then we won't have
the expected IPv4 gateway that the route poker needs to operate.
This iterates through them separately so that we treat the IPv4 and IPv6
sides of an address as separate interfaces which should allow the route
poker to find the one it wants (and just skip the IPv6 one).
DRY a chunk of repeated code for finding a free private range.
Also fix it so that it will consider 10.255.0.1/16 and 192.168.255.1/24
(previously it would only check up to octet 254).
If running as a service node, we ping core on a regular interval to
inform it we're running and in a good state. If we're an active
(not decommissioned or deregistered) service node and have too few
peers and thus we're not actually connected to lokinet, we should skip
that ping so core doesn't think we're ok.
Adds a fallback bootstrap file path parameter to CMake, specify
-DBOOTSTRAP_SYSTEM_PATH="/path/to/file" to use.
Adds a list of (currently 1) obsolete bootstrap RouterIDs to check
bootstrap RCs against. Will not use bootstrap RCs if they're on that
list.
Log an error periodically if we appear to be an active service node but
have fewer than a set number (5) known peers.
Bumps oxen-logging version for literal _format.
The `sign` target on macos was not working properly -- the signing
script would run before the build is finished. This was caused by
cmake/macos.cmake having an `if(BUILD_GUI)`, but BUILD_GUI isn't defined
as an option until cmake/gui.cmake, which hadn't been included yet where
macos.cmake was included.
This extracts just the `option(BUIL_GUI)` from gui.cmake into a separate
gui-option.cmake file that we can load earlier to fix it.
While here I also noticed the GUI_EXE setting was defined as an option,
but isn't actually a boolean value, as an option, but isn't actually a
boolean value, so fixed it by making it a `set(... CACHE FILEPATH ...)`.
If you stop/start the GUI but it doesn't exit on start, the second
--start (when lokinet is already running) waits for a state change that
doesn't come (because lokinet is already running). This add a check for
already-running so that we exit right away in such a case.
The tools to create a dmg on Apple are flakey, of course, and fail in
cryptic ways if the file already exists, so purge it in the
contrib/mac.sh script.
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.
The old one was way too big on mac relative to other icons. This scales
the background down, while keeping the black logo parts the same, and
changes the rounding of the corners to match native macos apps.
This also rewrites it from scratch to use a useful coordinate system
which allows drawing all the fundamentals in much more useful units.
- Add a function to extract a value from parsed options, to DRY out the
code a little bit.
- Add a exit_error function to format a message to stdout and then
return the code, to simplify the repeated print-and-return code used
when errors occur.
- Use fmt for output formatting
- Add an error if multiple modes are specified at once
(--up/--down/--status/--exit)
- Add error printing around unmap
- Accept empty string or `null` for token to mean "no token."
- Accept `null` for range to mean "default range."
- Don't use a default range (::0/0) in lokinet-vpn because this will
fail if IPv6 ranges aren't supported on the platform (e.g. on
Windows), and isn't necessary: if we omit it then the rpc code already
uses ::0/0 or 0.0.0.0/0 by default, as needed.
