Jeff Becker	061aebc964	reword auto-routing config comment	2 years ago
Jeff Becker	14ffdb6639	configurable route poker ... this allows you to use exit nodes without forcing routes over the interface, useful for using lokinet with an exit and selectively routing over the lokinet interface using an external socks proxy or binding to device explicitly. * make route poker configurable, defaults to enabled but allows disabling it on runtime if desired * add config option [network]:auto-routing to enable/disable route poker	2 years ago
Jeff Becker	da887dc559	implement exit node pooling, allows users to use multiple exits for an address range. ... mappings per ip stick to the same exit, each new ip is mapped to a random exit in the specified pool. make exit-auth multi value	2 years ago
Jeff	776e9227fd	make serivce::Endpoint::EnsurePathToService have a default timeout as a named constant.	2 years ago
Jeff	301b19bd0f	do not send buggy reply as rpc	2 years ago
Jeff	388fc53380	match io loop event order on windows/apple to match linux. ... on win32/apple reading packets from the interface does not count as an io operation. manually trigger pump on win32/apple to pretend that it is an io event. add platform quark function MaybeWakeUpperLayers on vpn::Interface to manaully wake up the other components on platforms that need that (ones on which packet io is not done via io events). on non linux platforms, use uv_prepare_t instead of uv_check_t as the former triggers before blocking for io, instead of after. this better matches linux's order of operations in libuv.	2 years ago
Jeff Becker	0e2b0edaf6	when lokinet looses ip4 connectivity libunbound used to freak out and only use ip6 after such an event. ... as a result dns queries stop working because we blackhole ip6 routes if exit mode is on. this prevents this case from being hit.	3 years ago
Jeff Becker	ec8d990163	demote log statement levels	3 years ago
Jeff Becker	172c2dec45	create new constexpr for the staleness window for introsets and use it in publishing introsets and intro selection	3 years ago
Jason Rhinelander	189c4bfba4	Also consider last publish; eliminate unwanted condition ... We don't really carry about when the last regen was attempted, but rather about when the last publish was attempted (or succeeded).	3 years ago
Jeff Becker	8ba03de44e	match timeouts in introset selection spread with logic for publishing	3 years ago
Jason Rhinelander	5115162066	Use libuv's cached current time for `time_now()` ... We are calling time_now() a huge amount, and it is a major consumer of CPU cycles, but we don't need it: most of the time the current event loop time is enough.	3 years ago
Jason Rhinelander	b2ee003329	Optimization: eliminate unneeded shared_ptrs ... We have a few cases where we're making an extra shared_ptr which we copy into a lambda, which then results in an extra unnecessary refcount decrement in the parent; this changes them to give an rvalue reference to the lambda to avoid the extra incr/decr instead. The one in Session::Pump is particularly noticeable and shows up in profiling.	3 years ago
Jason Rhinelander	7a04911b9b	Avoid std::function in hot pump code ... We're seeing overhead here of the std::function invocation, which we can easily avoid in this case by not using a std::function around the callback.	3 years ago
Jason Rhinelander	09c2b31b25	Move paths pumping into PumpLL	3 years ago

Jason Rhinelander	711038d150	Remove debug comment	3 years ago
Jason Rhinelander	0fe7153f6e	Fix client latency bug; De-shared_ptr IHopHandler queues ... - Replace m_FlushWakeup with a call to the router's god mode pump method. m_FlushWakeup apparently isn't enough to get things out, and we can end up with incoming packets that don't get properly handled right away without it. - The shared_ptr around the ihophandler queues isn't needed and is just adding a layer of obfuscation; instead just exchange the list directly into the lambda. - Use std::exchange rather than swap - A couple other small code cleanups.	3 years ago
Jason Rhinelander	70553c7627	Remove hopeless flush ... The TriggerPump just below this is *already* going to trigger a flush, so the extra flush call here can't do anything useful (and in particular, it won't clear up the queue *immediately*, which is what this code looks like it was aimed at doing).	3 years ago
Jason Rhinelander	fbc5cb0a6d	Add another missing pump trigger	3 years ago
Jason Rhinelander	bce7e2e56d	Pump outbound context	3 years ago
Jason Rhinelander	846577a0aa	Add missing inbound traffic pump trigger	3 years ago

Jason Rhinelander	b3a8160c89	Pump hidden context sooner ... This has to happen before pumping links because it is putting things on links.	3 years ago
Jason Rhinelander	0924dd8862	Remove dead declaration	3 years ago
Jason Rhinelander	f9395cd5dd	Cleanup: avoid pointless copy of `this` pointer	3 years ago
Jason Rhinelander	9844d358e6	Fix packet delay creep ... - Make the main PumpLL also pump hidden services, rather than using separate wakers in each TunEndpoint. It seems there is some interactions that just one or the other is not enough. - Eliminate TunEndpoint send queue -- it isn't needed as we can just send directly.	3 years ago
Jason Rhinelander	99b12940ad	Cleanups	3 years ago
Jason Rhinelander	e47d3098ac	Increase plaintext queue size from 32 to 512 ... In testing we were sometimes hitting a full queue error, which makes sense because the queue size seems really small. Increase it to 512.	3 years ago
Jason Rhinelander	78cc466bf2	Rename PumpLL -> TriggerPump ... And rename the actual pump implementation back to PumpLL.	3 years ago
Jason Rhinelander	031ea7aa37	Get rid of external event loop direct wakeups ... If something needs to wake up the event loop it should be using an async, as we are now with PumpLL(); but we had various code triggering a wakeup, expecting that PumpLL gets called on every wakeup, which isn't true anymore.	3 years ago
Jason Rhinelander	74215fc44c	Fix link layer delivery race condition (fix random ping delays) ... We trigger a pump immediately, but this is racey because we add to our plaintext data in a worker thread; if the worker thread runs after the pump then it ends up leaving plaintext to be handled, but there's no wakeup until the next one. This was the cause of seeing a random +1s and bunching added to ping responses sometimes: it wasn't until the *next* ping goes through the network that the plaintext queue gets processed, at which point it flushes the old one and often the new one together. The fix here gets rid of the map of sessions needing wakeups and instead adds an atomic flag to all of them to let us figure out which ones need to be flushed.	3 years ago

Jason Rhinelander	362fda5a56	Combine empty + pop into single call	3 years ago
Jason Rhinelander	b03f3c2d79	Remove another unwanted unconditional PumpLL	3 years ago
Jason Rhinelander	9113a6b36b	Triggered pumping ... This redoes how/when we pump so that we should only be calling the idempotent PumpLL() when we actually have (or may have) something to pump.	3 years ago
Jason Rhinelander	bfc6d35b33	Simplifications & C++17 ... - Modernize some iterator loops - Simplify a couple places by using `if (init; ...)` - Replace various std::binds with lambdas	3 years ago
Jason Rhinelander	41807f1763	transit hop: drop instead of flushing when full ... If full happens we are going to trigger a bunch of flushes which probably isn't very useful, so drop instead.	3 years ago
Jason Rhinelander	cf5c4e7284	outbound_message_handler: skip instead of aborting on removed paths	3 years ago
Jason Rhinelander	633431be66	Make outbound message queue PumpLL again if it doesn't send all	3 years ago

Jeff Becker	8a9025e234	only pump path context in idempotent pumpll	3 years ago
Jeff Becker	bb86996acf	make event loop pump function non idempotent	3 years ago
Jeff Becker	8744c93944	prevent 100% cpu usage on service nodes ... call_soon wakes up the mainloop and is often reentrant, we dont want to ever way up the event loop but we also want to always defer the call so we always use the workers	3 years ago
