From 5d847eed43007e7a68cf66fa76c9728b8a6525e4 Mon Sep 17 00:00:00 2001 From: Max Inden Date: Sun, 8 Sep 2024 11:16:55 +0200 Subject: [PATCH 01/85] perf: don't allocate in UDP send & recv path This change is best summarized by the `process` function signature. On `main` branch the `process` function looks as such: ```rust pub fn process(&mut self, dgram: Option<&Datagram>, now: Instant) -> Output { ``` - It takes as **input** an optional reference to a `Datagram`. That `Datagram` owns an allocation of the UDP payload, i.e. a `Vec`. Thus for each incoming UDP datagram, its payload is allocated in a new `Vec`. - It returns as **output** an owned `Output`. Most relevantly the `Output` variant `Output::Datagram(Datagram)` contains a `Datagram` that again owns an allocation of the UDP payload, i.e. a `Vec`. Thus for each outgoing UDP datagram too, its payload is allocated in a new `Vec`. This commit changes the `process` function to: ```rust pub fn process_into<'a>( &mut self, input: Option>, now: Instant, write_buffer: &'a mut Vec, ) -> Output<&'a [u8]> { ``` (Note the rename to `process_into` is temporary.) - It takes as **input** an optional `Datagram<&[u8]>`. But contrary to before, `Datagram<&[u8]>` does not own an allocation of the UDP payload, but represents a view into a long-lived receive buffer containing the UDP payload. - It returns as **output** an `Output<&'a [u8]>` where the `Output::Datagram(Datagram<&'a [u8]>)` variant does not own an allocation of the UDP payload, but here as well represents a view into a long-lived write buffer the payload is written into. That write buffer lives outside of `neqo_transport::Connection` and is provided to `process` as `write_buffer: &'a mut Vec`. Note that both `write_buffer` and `Output` use the lifetime `'a`, i.e. the latter is a view into the former. This change to the `process` function enables the following: 1. A user of `neqo_transport` (e.g. `neqo_bin`) has the OS write incoming UDP datagrams into a long-lived receive buffer (via e.g. `recvmmsg`). 2. They pass that receive buffer to `neqo_transport::Connection::process` along with a long-lived write buffer. 3. `process` reads the UDP datagram from the long-lived receive buffer through the `Datagram<&[u8]>` view and writes outgoing datagrams into the provided long-lived `write_buffer`, returning a view into said buffer via a `Datagram<&'a [u8]>`. 4. The user, after having called `process` can then pass the write buffer to the OS (e.g. via `sendmsg`). To summarize a user can receive and send UDP datagrams, without allocation in the UDP IO path. As an aside, the above is compatible with GSO and GRO, where a send and receive buffer contains a consecutive number of UDP datagram segments. --- neqo-bin/src/client/http09.rs | 16 +- neqo-bin/src/client/http3.rs | 20 +- neqo-bin/src/client/mod.rs | 54 ++- neqo-bin/src/server/http09.rs | 9 +- neqo-bin/src/server/http3.rs | 9 +- neqo-bin/src/server/mod.rs | 88 ++-- neqo-bin/src/udp.rs | 13 +- neqo-common/src/codec.rs | 88 ++-- neqo-common/src/datagram.rs | 99 ++++- neqo-crypto/src/selfencrypt.rs | 9 +- neqo-http3/src/connection_client.rs | 149 +++++-- neqo-http3/src/control_stream_local.rs | 8 +- .../tests/webtransport/negotiation.rs | 4 +- .../tests/webtransport/sessions.rs | 8 +- .../extended_connect/webtransport_session.rs | 8 +- .../extended_connect/webtransport_streams.rs | 4 +- neqo-http3/src/frames/hframe.rs | 4 +- neqo-http3/src/frames/tests/hframe.rs | 4 +- neqo-http3/src/frames/tests/mod.rs | 16 +- neqo-http3/src/frames/tests/reader.rs | 52 ++- neqo-http3/src/send_message.rs | 13 +- neqo-http3/src/server.rs | 31 +- neqo-http3/src/settings.rs | 4 +- neqo-http3/src/stream_type_reader.rs | 4 +- neqo-qpack/src/qpack_send_buf.rs | 4 +- neqo-transport/src/addr_valid.rs | 29 +- neqo-transport/src/connection/mod.rs | 378 +++++++++++------- neqo-transport/src/connection/tests/idle.rs | 5 +- neqo-transport/src/connection/tests/vn.rs | 4 +- neqo-transport/src/crypto.rs | 4 +- neqo-transport/src/fc.rs | 5 +- neqo-transport/src/frame.rs | 29 +- neqo-transport/src/packet/mod.rs | 212 ++++++---- neqo-transport/src/path.rs | 8 +- neqo-transport/src/pmtud.rs | 5 +- neqo-transport/src/recv_stream.rs | 36 +- neqo-transport/src/send_stream.rs | 43 +- neqo-transport/src/server.rs | 82 +++- neqo-transport/src/tparams.rs | 36 +- neqo-transport/src/tracking.rs | 20 +- neqo-transport/tests/connection.rs | 8 +- neqo-transport/tests/retry.rs | 12 +- neqo-transport/tests/server.rs | 31 +- neqo-udp/src/lib.rs | 80 +++- test-fixture/src/lib.rs | 6 +- test-fixture/src/sim/mod.rs | 4 +- 46 files changed, 1227 insertions(+), 528 deletions(-) diff --git a/neqo-bin/src/client/http09.rs b/neqo-bin/src/client/http09.rs index 9f99da9888..d1adb42c75 100644 --- a/neqo-bin/src/client/http09.rs +++ b/neqo-bin/src/client/http09.rs @@ -177,15 +177,13 @@ impl TryFrom<&State> for CloseState { } impl super::Client for Connection { - fn process_output(&mut self, now: Instant) -> Output { - self.process_output(now) - } - - fn process_multiple_input<'a, I>(&mut self, dgrams: I, now: Instant) - where - I: IntoIterator, - { - self.process_multiple_input(dgrams, now); + fn process<'a>( + &mut self, + input: Option>, + now: Instant, + write_buffer: &'a mut Vec, + ) -> Output<&'a [u8]> { + self.process_into(input, now, write_buffer) } fn close(&mut self, now: Instant, app_error: neqo_transport::AppError, msg: S) diff --git a/neqo-bin/src/client/http3.rs b/neqo-bin/src/client/http3.rs index 6031742c02..b0c7be7194 100644 --- a/neqo-bin/src/client/http3.rs +++ b/neqo-bin/src/client/http3.rs @@ -124,19 +124,17 @@ impl TryFrom for CloseState { } impl super::Client for Http3Client { - fn is_closed(&self) -> Result { - self.state().try_into() - } - - fn process_output(&mut self, now: Instant) -> Output { - self.process_output(now) + fn process<'a>( + &mut self, + input: Option>, + now: Instant, + write_buffer: &'a mut Vec, + ) -> Output<&'a [u8]> { + self.process_into(input, now, write_buffer) } - fn process_multiple_input<'a, I>(&mut self, dgrams: I, now: Instant) - where - I: IntoIterator, - { - self.process_multiple_input(dgrams, now); + fn is_closed(&self) -> Result { + self.state().try_into() } fn close(&mut self, now: Instant, app_error: AppError, msg: S) diff --git a/neqo-bin/src/client/mod.rs b/neqo-bin/src/client/mod.rs index ebbab98286..d7bf0bfca1 100644 --- a/neqo-bin/src/client/mod.rs +++ b/neqo-bin/src/client/mod.rs @@ -361,10 +361,12 @@ enum CloseState { /// Network client, e.g. [`neqo_transport::Connection`] or [`neqo_http3::Http3Client`]. trait Client { - fn process_output(&mut self, now: Instant) -> Output; - fn process_multiple_input<'a, I>(&mut self, dgrams: I, now: Instant) - where - I: IntoIterator; + fn process<'a>( + &mut self, + input: Option>, + now: Instant, + write_buffer: &'a mut Vec, + ) -> Output<&'a [u8]>; fn has_events(&self) -> bool; fn close(&mut self, now: Instant, app_error: AppError, msg: S) where @@ -380,13 +382,15 @@ struct Runner<'a, H: Handler> { handler: H, timeout: Option>>, args: &'a Args, + recv_buf: Vec, + send_buf: Vec, } impl<'a, H: Handler> Runner<'a, H> { async fn run(mut self) -> Res> { loop { let handler_done = self.handler.handle(&mut self.client)?; - self.process_output().await?; + self.process().await?; if self.client.has_events() { continue; } @@ -407,7 +411,7 @@ impl<'a, H: Handler> Runner<'a, H> { } match ready(self.socket, self.timeout.as_mut()).await?
