How to build

For the detailed information about building and developing Netty, please visit the developer guide. This page only gives very basic information.

You require the following to build Netty:

• Latest stable OpenJDK 8
• Latest stable Apache Maven
• If you are on Linux or MacOS, you need additional development packages installed on your system, because you'll build the native transport.

Note that this is build-time requirement. JDK 5 (for 3.x) or 6 (for 4.0+ / 4.1+) is enough to run your Netty-based application.

Branches to look

Development of all versions takes place in each branch whose name is identical to <majorVersion>.<minorVersion>. For example, the development of 3.9 and 4.1 resides in the branch '3.9' and the branch '4.1' respectively.

Usage with JDK 9+

Netty can be used in modular JDK9+ applications as a collection of automatic modules. The module names follow the reverse-DNS style, and are derived from subproject names rather than root packages due to historical reasons. They are listed below:

• io.netty.all
• io.netty.buffer
• io.netty.codec
• io.netty.codec.dns
• io.netty.codec.haproxy
• io.netty.codec.http
• io.netty.codec.http2
• io.netty.codec.memcache
• io.netty.codec.mqtt
• io.netty.codec.redis
• io.netty.codec.smtp
• io.netty.codec.socks
• io.netty.codec.stomp
• io.netty.codec.xml
• io.netty.common
• io.netty.handler
• io.netty.handler.proxy
• io.netty.resolver
• io.netty.resolver.dns
• io.netty.transport
• io.netty.transport.epoll (native omitted - reserved keyword in Java)
• io.netty.transport.kqueue (native omitted - reserved keyword in Java)
• io.netty.transport.unix.common (native omitted - reserved keyword in Java)
• io.netty.transport.rxtx
• io.netty.transport.sctp
• io.netty.transport.udt

Automatic modules do not provide any means to declare dependencies, so you need to list each used module separately in your module-info file.

netty-incubator-transport-io_uring's Issues

Why do we test the official benchmark results showing no difference between iouring and nio？

We used the official test program, but the results we got were almost no difference between iouring and nio. We use the official benchmark program, our test host has 32 cores, 200G RAM and the kernel version is 5.13.0

The following are our test codes.
`

import io.netty.bootstrap.ServerBootstrap;
import io.netty.channel.*;
import io.netty.channel.nio.NioEventLoopGroup;
import io.netty.channel.socket.SocketChannel;
import io.netty.channel.socket.nio.NioServerSocketChannel;

public class EchoNioServer {
private static final int PORT = Integer.parseInt(System.getProperty("port", "8088"));

public static void main(String []args) {
    System.out.println("start Nio server");
    EventLoopGroup group = new NioEventLoopGroup();
    final EchoServerHandler serverHandler = new EchoServerHandler();
    //boss用来接收进来的连接
    EventLoopGroup bossGroup = new NioEventLoopGroup();
    //用来处理已经被接收的连接;
    EventLoopGroup workerGroup = new NioEventLoopGroup();
    try {
        ServerBootstrap b = new ServerBootstrap();
        b.group(bossGroup, workerGroup)

Above is our test procedure, which is from the benchmark on the official website, but there is almost no difference in the results we measured.

Event Loop shutdown stuck due to uncompleted connect

Reproducer:

public class IOUringClientSocketConnectionShortTimeoutTest extends AbstractClientSocketTest {

   @BeforeAll
   public static void loadJNI() {
      assumeTrue(IOUring.isAvailable());
   }

   @Test
   @Timeout(value = 30000, unit = TimeUnit.MILLISECONDS)
   public void testConnectTimeoutAndClose(TestInfo testInfo) throws Throwable {
      run(testInfo, (bootstrap) -> {
         testFailedConnectWithSuperShortTimeout(bootstrap);
         bootstrap.config().group().shutdownGracefully().sync();;
      });
   }

   public void testFailedConnectWithSuperShortTimeout(Bootstrap cb) throws Throwable {
      cb.handler(new SimpleChannelInboundHandler<Object>() {
         @Override
         public void channelRead0(ChannelHandlerContext ctx, Object msgs)  {
            // Nothing will be sent.
         }
      });
      cb.option(ChannelOption.CONNECT_TIMEOUT_MILLIS, 1);
      ChannelFuture future = cb.connect("198.51.100.254", 65535);
      try {
         assertThat(future.await(30000), is(true));
      } finally {
         Assert.assertTrue(future.cause() instanceof ConnectTimeoutException);
      }
   }

   @Override
   protected List<TestsuitePermutation.BootstrapFactory<Bootstrap>> newFactories() {
      return IOUringSocketTestPermutation.INSTANCE.clientSocket();
   }
}

This test will hang forever (30 sec thanks to the test timeout) after requesting the group to shutdown gracefully, due to:

This will mimic what we're experiencing in the Vert-x test suite due to a very similar test (and few others, related server side, but still due to pending CQEs that never happen).

Expose IORING_REGISTER_IOWQ_MAX_WORKERS ring configuation

torvalds/linux@2e48005#diff-c729876d649dec0e07c0238dcb5bf0ef9fcb0ce8f9e810f57167d6896db45242 has introduced IORING_REGISTER_IOWQ_MAX_WORKERS to limit the number of kernel unbounded workers: it's beneficial for IOSQE_ASYNC submissions

Memory is not reclaimed after death of a process

When we run an app that uses io_uring, and then gracefully shutdown it - all following attempts to start it again fail because of OOM. Looks like shared buffers are not reclaimed when an app exits.

/proc/meminfo reports before and after are below.
Please look at Mapped and Shmem metrics.

Operation not permitted

Hello, this issue is linked to io_uring but not really netty but I would like to know if some of you could help me. I'm trying the io uring in a docker container, and when I start it, I got this error every time.

java.lang.RuntimeException: failed to create io_uring ring fd Operation not permitted at io.netty.incubator.channel.uring.Native.ioUringSetup(Native Method) ~[onefork.jar:git-OneFork-47e86db] at io.netty.incubator.channel.uring.Native.createRingBuffer(Native.java:141) ~[onefork.jar:git-OneFork-47e86db] at io.netty.incubator.channel.uring.Native.createRingBuffer(Native.java:174) ~[onefork.jar:git-OneFork-47e86db] at io.netty.incubator.channel.uring.IOUring.<clinit>(IOUring.java:36) ~[onefork.jar:git-OneFork-47e86db]

Without docker, the server starts normally but looks like Docker hasn't the permission and I can't find how to fix it. Thank you!

Kernel warning and instability in 5.10

I am seeing some dodgy behavior in 5.10. We did upgrade to 5.15 and that seemed to fix things, but leaving this here for posterity in case anybody else runs into the same issue. The IOUringEventLoopGroup appears to start and then fail to handle any tasks. The Java application appears to continue to run without exceptions or failures. Successive runs cause the kernel to seize up and for the networking to be come unresponsive in a cloud environment (AWS) rendering the instance wholly unusable. There also appeared to be some occasional page faults in there as well. Looks like some sort of internal kernel data structures are getting corrupted. Is this just a buggy kernel version? Should this project increase the minimum supported kernel?

Seems to be coming from https://elixir.bootlin.com/linux/v5.10.118/source/lib/iov_iter.c#L1095

Possible lead from https://man.archlinux.org/man/io_uring_setup.2.en

Before version 5.11 of the Linux kernel, to successfully use this feature, the application must register a set of files to be used for IO through io_uring_register(2) using the IORING_REGISTER_FILES opcode. Failure to do so will result in submitted IO being errored with EBADF. The presence of this feature can be detected by the IORING_FEAT_SQPOLL_NONFIXED feature flag. In version 5.11 and later, it is no longer necessary to register files to use this feature. 5.11 also allows using this as non-root, if the user has the CAP_SYS_NICE capability.

0.0.6.Final

Support flags when io_uring_setup

seems current flags in io_uring_params is 0 by default, is there any plan to support configurations to io_uring_setup?

When will fileRegion be supported?

The io_uring transport does not currently support fileRegion, when will fileRegion be supported? We are eager to try iouringFileRegion.

Default iosqeAsyncThreshold slow for many connections

The default iosqeAsyncThreshold (25) is comparatively slow when benchmarking many connections. This is a simple HTTP benchmark ( https://github.com/yawkat/micronaut-http-benchmarks/tree/262d50b525004c2c6dcd3fea8a442bab707fd638/test-case-pure-netty ). Each subplot shows a different request rate. The y axis is the request latency, the x axis the latency percentile. Blue is the default iosqeAsyncThreshold, Orange is an iosqeAsyncThreshold turned up to Integer.MAX_VALUE. The connection count is min(rps, 20000), i.e. for the low request rates each connection gets ~1 req/s, but it maxes out at 20000 connections so at the higher request rates there may be more req/s on each connection.

As you can see, in all tested scenarios, IOSQE_ASYNC adds >30µs to the request latency. It also seems to worsen the max throughput. In a separate benchmark vs nio, this lead to worse performance for io-uring.

Thanks @franz1981 for pointing me towards this setting and its impact.

IPv4-mapped IPv6 addresses are shown as IPv6 addresses when they should be shown as IPv4 ones

Now that #10 is fixed I found a minor issue. More of a nit than anything.

IPv4-mapped IPv6 addresses differ from what is shown with epoll. For instance, consider the IPv4-mapped IPv6 address :ffff:127.0.0.1. In the epoll transport this is represented as just 127.0.0.1, but with the io_uring transparent it shows as the IPv6 address /0:0:0:0:0:ffff:7f00:1%0 instead.

Dual IP stack problems when IOUring is initialized (even not used)

We have a simple class that checks available polling libraries (epoll, iouring) and provides the best one (see below).
When we disable uring (by removing 'iouring.enabled' from the command line) its expected that behaviour will be the same as if iouring completely removed from the code and dependencies.

Nevertheless, when we keep it in place (without even using it - epoll is used - 4.19 kernel wouldn't allow to use iouring) we experience some problems with IPv6 stack:
Address family not supported by protocol: /[2a01:b740:a41:20d:0:0:0:9]:443
Outgoing connection to [2a01:b740:a41:20d:0:0:0:9]:443 failed

So when the library is initialized it somehow breaks IPv6 stack.
Removing dependency and iouring-related strings fixes problem.
Will provide MRE later.

Add IOSQE_ASYNC_HYBRID support

torvalds/linux@90fa028 has introduced IOSQE_ASYNC_HYBRID that would be beneficial "in cases where unbound max_worker is relatively small" (quoting the commit msg).

We should also provide some guidance/doc/readme to tell users to limit the number of max_workers as #106 shows that people would get a huge amount of time spent by lot of kernel threads to async complete unbound I/O work

centos 8.4-Kernel: 4.18, it throwed " failed to load the required native library"

i passed all tests of "the netty-incubator-transport-io_uring", but it still throwed exceptions.

AbstractIOUringStreamChannel iovArray litter

Every time there is a writev, an IovArray instance is created. Also, there is the overhead of pooling the memory of the iovArrayBuffer.

 @Override
        protected int scheduleWriteMultiple(ChannelOutboundBuffer in) {
            assert iovArray == null;
            int numElements = Math.min(in.size(), Limits.IOV_MAX);
            ByteBuf iovArrayBuffer = alloc().directBuffer(numElements * IovArray.IOV_SIZE);
            iovArray = new IovArray(iovArrayBuffer); <-----
            try {
                int offset = iovArray.count();
                in.forEachFlushedMessage(iovArray);
                submissionQueue().addWritev(socket.intValue(),
                        iovArray.memoryAddress(offset), iovArray.count() - offset, (short) 0);
            } catch (Exception e) {
                // This should never happen, anyway fallback to single write.
                iovArray.release();
                iovArray = null;
                scheduleWriteSingle(in.current());
            }
            return 1;
        }

Perhaps it would be better to preallocate the iovArray with ByteBuff of size:

ByteBuf iovArrayBuffer = alloc().directBuffer(IOV_MAX * IovArray.IOV_SIZE);
iovArray = new IovArray(iovArrayBuffer); 

This way the iovArray is always big enough for any number of buffers.

So the usage would look something like this:

 @Override
        protected int scheduleWriteMultiple(ChannelOutboundBuffer in) {
            iovArray.clear();
            try {
                int offset = iovArray.count();
                in.forEachFlushedMessage(iovArray);
                submissionQueue().addWritev(socket.intValue(),
                        iovArray.memoryAddress(offset), iovArray.count() - offset, (short) 0);
            } catch (Exception e) {
                // This should never happen, anyway fallback to single write.
                scheduleWriteSingle(in.current());
            }
            return 1;
        }

One drawback of preallocating is that it will consume extra memory. So with a 64 bit JVM and 1024 as IOV_MAX, this would be around '2 * 8B * 1024 = 16KB'. So perhaps that would be a reason to not pool by default.

Not Fired timers leak into the kernel

This has been reported by @pveentjer in a private conversation about io_uring Netty mechanics.

1. schedule a timer in 2 minutes
2. await till the IoUring event loop park/wait
3. schedule a second timer 10 seconds which is going to replace the last deadline set
4. once it fires, the next in-line scheduled task was the previous one of 2 min(now <= 1m50s, likely): the event loop arm a timer for this deadline (<= 1m50s) BUT there was already such a timer, hence we arm it twice!

If we have a huge amount of already registered timers in the future, they will see their registrations to always happen twice, if their deadline is replaced with a new recent one.

Update the timer through a remove (via IORING_TIMEOUT_UPDATE) require >=5.11, while removing the existing one (when the new recent one need to be armed) is >=5.5.
There are several ways to address it, including NOT addressing it, but it can still cause silently to goes OOM or worse (no idea really).

I believe we had no covering for this because our await operations didn't allow any level of concurrency: if we block awaiting, is a blocking operations, period. But if we request to be awaken in the future, and we're awaken earlier, the same "in flight" request is not yet completed, hence allow to enqueue more and more of this.

Problem with os.detected.arch on AARCH64

I know that this library does not support AARCH64 at the moment but I tried to build it and see whether I can help supporting it.

Running mvn clean package starts with:

[INFO] Detecting the operating system and CPU architecture
[INFO] ------------------------------------------------------------------------
[INFO] os.detected.name: linux
[INFO] os.detected.arch: aarch_64

and later fails with:

netty-transport-native-unix-common:4.1.54 does have a binary for aarch64 but there is no _ in its classifier (linux-aarch64):

https://repo1.maven.org/maven2/io/netty/netty-transport-native-unix-common/4.1.54.Final/netty-transport-native-unix-common-4.1.54.Final-linux-aarch64.jar

I have no idea why os-maven-plugin puts this _ in the arch name (https://github.com/trustin/os-maven-plugin/#property-osdetectedarch) but this leads to issues like this one and netty/netty-tcnative#552.

`java.lang.UnsatisfiedLinkError: could not load a native library: netty_transport_native_io_uring_x86_64`

Hey Gurus,

I'm trying to use zio-http with io_uring. However I got java.lang.UnsatisfiedLinkError: could not load a native library: netty_transport_native_io_uring_x86_64 somehow.

eval println(IOUring.unavailabilityCause().toString()) will show java.lang.UnsatisfiedLinkError: could not load a native library: netty_transport_native_io_uring_x86_64

I'm running it on Linux madbox 5.14.8 #1-NixOS SMP Sun Sep 26 12:10:25 UTC 2021 x86_64 GNU/Linux

JVM crashes on `Native.ioUringSetup()`

I'm not sure how I can reproduce this, but I sometimes get a JVM crash when I try to load transport-io_uring on AdoptOpenJDK 15.0.2, Ubuntu 18.04.3. I know Ubuntu 18.04 runs a very old kernel and thus there's no point of loading io_uring, but I think it still shouldn't crash, because otherwise I can't figure out io_uring is available or not.

This may be relevant or not, but I load transport-epoll first, and then load transport-io_uring.

Here's the JVM crash log:

Remote addresses from server channels do not make sense

Using Netty 4.1.54.Final and 0.0.1.Final of the io_uring transport. I am connecting to a server using TCP listening on a io_uring event loop, but it reports nonsensical remote addresses like 8000:bc:307f:0:0:0:0:0%37 (I was really connected from the IPv4 loopback address 127.0.0.1) and 8000:84:e17f:0:2829:4c69:6f2f:6e65%37 (I was really connected from the IPv6 loopback address ::1). These issues don't appear with the traditional epoll event loop.

I cannot find a way to make tests to run, probably I've missed something obvious

blocking eventfd in IOUringEventLoop.java

Hi there,
I found there is a blocking eventfd in IOUringEventLoop.java, since I'm not familiar with java and netty, could any tell me what is it for?
Here the thing is an eventfd without O_NONBLOCK flag will trigger io-wq threads in io_uring. Is reading/writing for this eventfd high frequency operations? If yes, then in systems that has few cpu resources, it may affect the service quality, I guess.

Regards,
Hao

Some requests are received and processed twice?

I'm running on the latest "release" of io_uring (0.0.13.Final). I recently noticed build failures on GitHub Actions which seem the be caused
by io_uring. Removing io_uring and only testing against epoll/kqueue/nio works perfectly fine.

I had originally two issues, one of them I was able to solve myself. However, that might be interesting as well: I have some code which did a websocket handshake, I executed it and called syncUninterruptedly which began to fail as well. Seems like I need to execute/handle that async, wich worked seemlessly a few days ago.

On the other hand I am testing if sent http requests are having the same request method when receiving. In a nutshell this code looks like this:

        Assertions.assertEquals(SUPPORTED_METHODS.get(handledTypes.getAndIncrement()), context.request().method());
        // send ok http response

And I send the request with an HttpUrlConnection:

    for (String supportedMethod : SUPPORTED_METHODS) {
      HttpUrlConnection connection = construct_here;
      connection.setRequestMethod(supportedMethod)
      connection.connect();

      Assertions.assertEquals(200, connection.getResponseCode());
    }

But I receive some requests twice:

    SENDING WITH GET
    GOT GET /// 0 /// IOUringEventLoopGroup-7-1
    SENDING WITH POST
    GOT POST /// 1 /// IOUringEventLoopGroup-7-2
    SENDING WITH HEAD
    GOT HEAD /// 2 /// IOUringEventLoopGroup-7-3
    SENDING WITH OPTIONS
    GOT OPTIONS /// 3 /// IOUringEventLoopGroup-7-3
    GOT OPTIONS /// 4 /// IOUringEventLoopGroup-7-4

or

    SENDING WITH GET
    GOT GET /// 0 /// IOUringEventLoopGroup-7-1
    SENDING WITH POST
    GOT POST /// 1 /// IOUringEventLoopGroup-7-2
    SENDING WITH HEAD
    GOT HEAD /// 2 /// IOUringEventLoopGroup-7-2
    GOT HEAD /// 3 /// IOUringEventLoopGroup-7-3

I'm pretty sure that the request is not sent twice as that test works fine with epoll and nio. I wasn't yet able to validate this, but there was a recent kernel update which changed stuff related to io_uring, maybe it's a good start to check if it works fine on older kernel versions? (https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=42a7b4ed45e7667836fae4fb0e1ac6340588b1b0)

zlib and io_uring

hey,

we have a pretty large codebase so I'll try to pull out the most important parts

we essentially dropped in epoll support whereas before we used nio - no issue there.
we later deployed kernel 5 + io_uring with the io_uring module, and we started to have issues. we compress the network stream data with zlib (mostly implemented native to avoid copying bytebuf)

error flows from here: https://github.com/SpigotMC/BungeeCord/blob/master/native/src/main/c/NativeCompressImpl.cpp#L76

always errors showing -2. I would usually attribute this to a bug on our side, but the issue only surfaces when we put the "proxy" type server on io_uring, as epoll and nio work without issue. not sure what kind of logs you guys need but I can try to provide anything requested.

JVM crash on startup

Hey,

I was looking forward to test around with io uring. I'm trying to start an application which contains the library, relocated to libeu_cloudnetservice_relocate_netty_transport_native_io_uring_x86-64.so (loading works as expected, relocating using gradle shadow relocate("META-INF/native/libnetty", "META-INF/native/libeu_cloudnetservice_relocate_netty")), as described in the docs. The relocated application startup fails with this error, my other application without relocating works fine.

Hopefully someone can give some information if this is a bug of the implementation or if I'm doing something wrong.

Thanks in advance!

I always getting error

I try for real application with 2000more device connected to my server, but I am getting error io.netty.channel.unix.Errors$NativeIoException: bind(..) failed: Address already in use, that is never happen in Epoll before...

IOUring uses more heap memory than Epoll transport

We have integrated IOUring into our communication layer as an experimental feature, after which I did some comparison test between EPOLL and IOURING I want to share some info.

I ran small load test and noticed that IOURING transport uses more heap memory than EPOLL with same load.

1. EPOLL
   

2. IOURING
   

After that I decided to use the async-profiler and check memory allocation for both transport. After briefly comparing two flame graphs I found that io.netty.incubator.channel.uring.IOUringSubmissionQueue#setData allocate allot of java.lang.Integer and java.lang.Long.

I think it's because we use

            logger.trace("UserDataField: {}", userData);
            logger.trace("BufferAddress: {}", bufferAddress);
            logger.trace("Length: {}", length);
            logger.trace("Offset: {}", offset);

without check logger.isTraceEnabled() , since we pass a primitive and the method takes an Object as parameter, we allocate the new object each time.

io_uring cannot allocate memory

In the FAQ:

$ ulimit -l
65536

I dug through all the layers to increase the memlock limit for a program running in a docker container. Increased the limit to 1GB. It still failed.

Thankfully, transitive dependency exclusion came to the rescue.

fd reuse cause new connection to be deregistered

File Descriptor reuse can cause this sequence of bad events to happen for a connection:

1. issue a POLL_IN SQEs, awaiting data to be received (due to auto-read)
2. user code request to close the connection: given that there's no scheduled I/O (read/write)
   a new CLOSE SQE is submitted and it invoke a fireChannelInactiveAndDeregister,
   that will enqueue (via invokeLater) a doDeregister.
   The fd is now marked as "closed" (but not yet deregistered)
3. deregistering cannot happen due to the previously scheduled POLL_IN: instead, it enqueue 2 POLL_REMOVEs
4. CLOSE complete and the CQE pass through IOUringEventLoop::handle without being handled (because it isn't a "delayed close", the fd is already marked as "closed"!)
5. a new connection is created, reusing the previous one's fd (that is effectively closed, from the OS pov): IOUringEventLoop replace the closed channel with the new one
6. a POLL_IN CQE with ERRNO_ECANCELED_NEGATIVE status complete, but given that there are none yet scheduled for the new channel, nothing bad happen
7. POLL_REMOVE CQEs complete and, if for the new connection there's nothing scheduled (read/write/connect/poll/...), it will straight removed from the map of handled channels!

This will makes the state of Netty's connections to not being in sync with what the OS think the fd is.

Use io_uring with `respectMaybeMoreData` flag for `RecvByteBufAllocator`

I found that if respectMaybeMoreData = false and maxMessagesPerRead > 1, then channelReadComplete is not called

            allocator.respectMaybeMoreData(false);
            allocator.maxMessagesPerRead(2);

            Bootstrap b = new Bootstrap();
            b.group(group)
                    .channel(IOUringSocketChannel.class)

                            ChannelPipeline p = ch.pipeline();
                            p.addLast(new HttpClientCodec());

            String host = "google.com";
            int port = 80;

            DefaultHttpRequest request = new DefaultHttpRequest(HttpVersion.HTTP_1_1, HttpMethod.GET, "http://" + host + "/");
            request.headers().set(HttpHeaderNames.HOST, host);


            // Start the client.

                    channel.writeAndFlush(request);
                } else {
                    channelFuture.cause().printStackTrace();
                }
            });

            // Wait until the connection is closed.
            f.channel().closeFuture().sync();
        } catch (InterruptedException e) {
            e.printStackTrace();
        } finally {

IOUringEventLoop nextWakeupNanos

In the IOUringEventLoop the nextWakeupNanos is updated twice:

nextWakeupNanos.set(curDeadlineNanos);
...
if (nextWakeupNanos.get() == AWAKE || nextWakeupNanos.getAndSet(AWAKE) == AWAKE){  
   pendingWakeup = true;
}

The nextWakeupNanos is an AtomicLong and the set and getAndSet are not very cheap. On the X86 the trigger a memory fence which effectively causes the CPU to stop issuing loads till the store buffer has been drained. And this will not benefit performance.

Based on the code it seems that the nextWakeupNanos is not used by any other thread. Perhaps I'm missing something since I didn't study the code in-depth, but I think the nextWakeupNanos could be converted to a simple plain long.

THe IOUringSubmissionQueue already has the appropriate fences.

Use io_uring fast-poll or poll op's multi-shot

Seems that for regular socket send/recv operations, current implementation still uses one pair of poll op and send/recv op, which is inefficient. Below perf report shows that io_poll_add() introduces obvious overhead.

• 51.79% 0.31% IOUringEventLoo [kernel.kallsyms]
• 51.48% io_issue_sqe
  • 32.98% io_write
  • 12.26% io_read
  • 4.35% io_poll_add
    • 4.31% __io_arm_poll_handler
      • 3.72% sock_poll
        • 3.40% tcp_poll
          2.54% _raw_spin_unlock_irqrestore
  • 1.79% io_assign_file

I wonder whether we can use IORING_FEAT_FAST_POLL or IORING_OP_POLL_ADD's IORING_POLL_ADD_MULT feature, which will reduce most io_poll_add calls.

version 0.0.6 on maven central

Hi!
First of all, thank you very much for this library, I tried it on our workloads and it shows very nice results!

I noticed you released version 0.0.6 but on maven central only 0.0.5 is available. Is it possible to publish an artefact with 0.0.6 version over there?
For more details see this issue redis/lettuce#1786

Thanks

netty io_uring was slower than epoll

I collected some stats on x86, 5.13 kernel, using netty-incubator-iouring 13 with Cassandra 4.0. The network throughput is about 8% lower than netty epoll. The context switches is 69% higher than than epoll, and the interrupts are 2% higher than epoll. Also, CPI (circles per instruction) is 8% higher.

	iouring	epoll	diff
load	1000	1000		Actual	Calculated
throughput	142868	154465	1.081	8.1	11.4

Support TCP Fast Open in IO_URING Socket Channel

TCP Fast Open support is missing in IO_URING Socket Channel implementations.

Support for Netty 5

Currently, Io_Uring transport is supported only for Netty 4.1. It'd be great if we support the upcoming Netty 5.

Add profile for cross-compile for aarch64

Let's add a profile to be able to cross-compile for aarch64 the same as we do for other netty projects

random machine reboots whilst using io_uring

we deployed some io_uring stuff to end-user facing stuff (essentially giant reverse proxies) that run Netty.

we usually average around 800 concurrent connections on each, during busy periods scaling up to 2000 on each. when we run this using the io_uring transport, after a few hours, the machines just simply die (nothing in logs relating to a reboot, etc). tried on various Debian versions, different machines, different kernel versions. the only constant is that when we run it w/ io_uring, the machines die. willing to provide any logs requested, but the issue is that its almost as if someone unplugged the power cable to these servers (no reboot feedback in syslog, events etc).

could this be related to some form of leak in either kernel io_uring or the c implementation in the Netty impl?
