Error running `mdns_responder` example on ESP32C3 #24

Closed Luni-4 closed 3 weeks ago

Luni-4 commented 1 month ago

My issue could be caused by my lack of experience and knowledge, so sorry in advance if that's the case.

I can build the mdns-responder example on esp32c3, but I cannot flash and run it because I'm getting the following error repeatedly:

MabezDev commented 1 month ago

Could you also post your sdkconfig.defaults?

Luni-4 commented 1 month ago

Sure, here the sdkconfig.defaults:

CONFIG_ESP_MAIN_TASK_STACK_SIZE=20000
CONFIG_ESP_SYSTEM_EVENT_TASK_STACK_SIZE=4096

MabezDev commented 1 month ago

If you're doing a lot in main, without spawning any other threads you're probably hitting a stack overflow. Does increasing CONFIG_ESP_MAIN_TASK_STACK_SIZE and rebuilding help?

Luni-4 commented 1 month ago

I've added to the first comment my code. I had also tried to increase CONFIG_ESP_MAIN_TASK_STACK_SIZE=40000 but nothing changed, same error

MabezDev commented 1 month ago

I would try even bigger stacks maybe CONFIG_ESP_MAIN_TASK_STACK_SIZE=80000? It's unlikely to be anything else when it explicitly detects and overflow, but maybe @ivmarkov knows more.

Are you absolutely sure your sdkconfig.defaults is picked up? Is it in the root of the crate? Did you do - just in case - cargo clean? I am - as we speak - running a much more complex project that amongst other things uses the edge-mdns responder with only 45KB stack.

I've also tried to run cargo clean and then cargo run, but nothing has changed. I'm using the last Rust nightly version.

This is the error I get with CONFIG_ESP_MAIN_TASK_STACK_SIZE=40000

ivmarkov commented 1 month ago

This is the content of my foo-esp directory after running the ls -la command

OK. So sdkconfig.defaults is in the correct location. Read on.

I've also tried to run cargo clean and then cargo run, but nothing has changed. I'm using the last Rust nightly version.

Everything had changed. Before, you were claiming this error (with stack size of 40KB):

I (329) main_task: Calling app_main() Guru Meditation Error: Core 0 panic'ed (Stack protection fault).

Now, you are reporting this error (again, with stack size of 40KB):

assert failed: tcpip_send_msg_wait_sem /IDF/components/lwip/lwip/src/api/tcpip.c:449 (Invalid mbox)

These are two completely different errors. The fact, that you get the "Invalid mbox" error in the lwIp stack does mean, that the stack size issue is no longer an issue. So something had changed - for the better.

Now, for the second error:

You get it, because the networking layer of ESP IDF is not initialized yet. In other words, even if you didn't get the second error, the code you have just wouldn't do anything, simply because the mDNS responder does not have an ethernet device (and IP stack on top) via which it could send/receive UDP packets in the first place.

The example you have copied can only run verbatim on regular PCs only, where the ethernet connection and the network interfaces are up and running before the start of your app, because you have an OS underneath your app, and when booting it, the OS took care of bringing up either ethernet, or Wifi for you - automatically.

In the embedded MCU world (ESP IDF included), you need extra steps to bring up either an Ethernet interface or a Wifi interface or both.

Assuming you want a Wifi interface, you need some code similar to this example. This code needs to run before the code you have so far which is trying to bring up the mDNS responder.

(BTW, while running the mDNS responder, please keep the wifi variable around and don't drop it, as that would drop the wifi interface and you'll get to square 0 again.)

Please let me know if it works for you once you incorporate the changes I suggest. There might be a need to do one more thing, but let's go step by step. And if you hit a stack size issue again, increase the stack size with the conf setting. There are ways to reduce the stack size usage, but then again - step by step.

Luni-4 commented 1 month ago

Thanks a lot @ivmarkov for your explanation, very appreciated, clear and concise! :)

Ok, I've tried to replicate the Wiifi interface code you linked to me. This is the result. First, I run cargo clean and then cargo run.

Rebooting...

Luni-4 commented 1 month ago

Ok, I was able to avoid the stack issue, setting CONFIG_ESP_MAIN_TASK_STACK_SIZE=120000.

Now I get a weird error, though:

I (19253) esp_idf_svc::wifi: EspWifi dropped
I (19253) esp_idf_svc::netif: Dropped
I (19253) esp_idf_svc::netif: Dropped
I (19263) wifi:Deinit lldesc rx mblock:10
I (19273) esp_idf_svc::nvs: NvsDefault dropped
I (19273) esp_idf_svc::eventloop: System event loop dropped
Error: ESP_ERR_TIMEOUT
I (19273) main_task: Returned from app_main()

I've tried to add a infinite loop to avoid the timeout, but same error

loop {
        // Sleep for one second and then continue the execution.
        std::thread::sleep(std::time::Duration::from_millis(1000));
}

Put this in sdkconfig.defaults:

CONFIG_PTHREAD_TASK_STACK_SIZE_DEFAULT=8192

ivmarkov commented 1 month ago

This error

***ERROR*** A stack overflow in task pthread has been detected.

Is not in your main() thread but in the hidden async-io thread so you need to increase the stack of that thread, hence the above parameter.

As for the timeout - I'll follow up shortly.

Luni-4 commented 1 month ago

Thank you!

I tried with your change, so I had reverted the MAIN_TASK value to 40000, and now sdkconfig.defaults is:

CONFIG_ESP_MAIN_TASK_STACK_SIZE=40000
CONFIG_ESP_SYSTEM_EVENT_TASK_STACK_SIZE=4096
CONFIG_PTHREAD_TASK_STACK_SIZE_DEFAULT=8192

And now I get this error:

other than the timeout error from before

Paste your code somewhere. I'll try it out at my end.

Thanks a lot! I've pushed the entire repository here

Thanks a lot! Now it works perfectly! :)

Sometimes, when I launch cargo run, the ESP_ERR_TIMEOUT appears, but I do not think it is related to this issue. You can fix that, launching cargo run again.

A small update.

I was able to work around the ESP_ERROR_TIMEOUT issue with the unwrap() function instead of stack unwinding the various errors. When a timeout occurs, ESP32-C3 panics, reboots, and it can now connect to Wi-Fi.

I have also reduced the stack usage to CONFIG_ESP_MAIN_TASK_STACK_SIZE=70000 building with the following release profile and using the unwrap() function everywhere in the main code.

[profile.release]
codegen-units = 1 # LLVM can perform better optimizations using a single thread
debug = 2
debug-assertions = false
incremental = false
lto = 'fat'
# Optimize for binary size, but with loop vectorization.
opt-level = 's'
overflow-checks = false

I do not know if it's the correct way, but it seems to work for me now. Thanks again @ivmarkov and @MabezDev for your help! :)

The ESP_ERR_TIMEOUT is in the meantime fixed in esp-idf-svc itself, so if you [patch.crates-io] all esp-idf-* versions to their git master, it should disappear.

As for (ab) using unwrap specifically to reduce stack size - this is likely having zero influence on your stack usage.

Oh, thanks! I'm going to update my dependency soon then.

Hmm, this is weird then. I have tried to use that release profile without using unwrap, but no stack changes at all. I have always run cargo clean before any cargo run --release command. Perhaps I screwed up somewhere else, I need to verify.

I have tried to update the Cargo.toml adding these patches:

[patch.crates-io]
esp-idf-hal = { git = "https://github.com/esp-rs/esp-idf-hal" }
esp-idf-sys = { git = "https://github.com/esp-rs/esp-idf-sys" }
esp-idf-svc = { git = "https://github.com/esp-rs/esp-idf-svc" }

and increasing the version in .cargo/config.toml to:

[env]
# Enables the esp-idf-sys "native" build feature (`cargo build --features native`) to build against ESP-IDF (v5.2.1)
ESP_IDF_VERSION = { value = "tag:v5.3.1" }

but I get this error

If I switch back to ESP_IDF_VERSION = { value = "tag:v5.2.2" } with the patches, the example compiles, but the timeout problem remains

ivmarkov commented 1 month ago

By upgrading both to master versions of the esp-idf-* crates, as well as upgrading to ESP IDF V5.3.1, where support for ESP IDF 5.3 is not even released yet, you take two risks simultaneously.

Stay with ESP IDF 5.2.2 max, while still using the master versions of the esp-idf-* crates.

Even though the error you are reporting should've been fixed by this: https://github.com/esp-rs/esp-idf-svc/commit/fb03bd77785a48672a7184c1393959e9e62da75e

Perhaps you should issue a cargo update?

Hmmm, I don't have a good explanation for that. :(

For me - at least on the c6 - the TIMEOUT issue is fixed with latest master.

I've tried to update esp-idf-svc through git and branch master, but now I cannot build the project anymore. I get this error because it seems that this API has been removed:

There is an alternative API in this file. Just look inside this module.

@ivmarkov

I have replaced that API with

You have to keep around the MountedEventfs thing returned from this call or else it would be immediately dropped and you achieve nothing.

Luni-4 commented 1 month ago

Yay, it works! Thanks a lot!

I had to update ESP IDF to v.5.3.1 to solve the ESP_ERROR_TIMEOUT issue on ESP32-C3 though. But now I'm not finding any more problems issuing cargo run many times in a row.

Unfortunately, I'm facing another problem with this example. When I run avahi-browse -a this is the output I get after some time:

+  device IPv4 service-name                                         Secure Web Site      local
-   device IPv4 service-name                                         Secure Web Site      local

It seems as if it shuts down itself after a while. Is this a wrong configuration on my side or is it a bug?

@ivmarkov

I have pushed the final code here. I have added the mdns service responder example, but the issue pointed out in the message above remains.

I have pushed the final code here. I have added the mdns service responder example, but the issue pointed out in the message above remains.

If you would like me to help with this issue, you have to do some basic checks yourself as well. For example:

Are you sure that the device does not lose power (if e.g. connected to a laptop that might into standby)?
Are you looking at the device logs? Could it be, that the device gets disconnected from wifi? Or are you seeing any other errors there?
Perhaps you can implement a simple loop on the device that runs in parallel with the mDNS responder, and which loop tries - every X seconds - to ping your gateway IP?

I hope you realize, that simply telling me "it seems as if it shuts down itself after a while" is not enough to even hypothesize what might be happening. :-)

Luni-4 commented 1 month ago

Yeah, you're right. I was erroneously supposing that my issue was a general and reproducible issue which might not have been specific to my environment, apologies for that.

A little of context. I have an ESP32-C3 and a laptop as devices. Both of them are connected through Wi-Fi to the same router. The ESP32-C3 is connected to the laptop through serial. At first, I issue the cargo run --release command in order to flash and run the code linked above, then, in another terminal, I issue the avahi-browse -a command from the laptop to verify if I can discover the device. Initially I can find the ESP32-C3 device and ping it, but after a while (nearly a minute), it occurs this in the avahi-browse log:

+  device IPv4 service-name                                         Secure Web Site      local
-   device IPv4 service-name                                         Secure Web Site      local

This is the log produced by the ESP32-C3

I have also tried to connect the ESP32-C3 to a power supply far from my pc and see if I can discover the device, but the issue remains.

For what concerns your questions:

The laptop doesn't go into standby
I pasted the devices logs above. I opened the router gateway configuration from browser and ESP32-C3 is still connected to the network. To better verify that, I have also added an HTTP server to my offline code, and it works. I can push this addition to my repository if it can be of help. I cannot see any other errors around.
Actually, I had not thought at this solution, thanks! I'm going to later report the results

As a final test, I have also tried to replace

loop {
        // Sleep for one second and then continue the execution.
        std::thread::sleep(std::time::Duration::from_millis(1000));
    }

with

loop { }

but the issue persists the same.

Thanks a lot for your help! I hope I have provided a comprehensive explanation. I can add more information if necessary.

ivmarkov commented 1 month ago

Thanks for the detailed explanations. Looking at your logs, there does not seem to be any error output in the ESP device logs. Furthermore, it seems the device continues to reply on mDNS queries from both your gateway and other IPs (if you could confirm that the "replying to mDNS" blah blah log continues to happen when you trigger an avahi-browse command after a while).

What I can try to do (but tmr) is to try to run your example at my end, and see if it breaks on me.

As for:

As a final test, I have also tried to replace

loop {
        // Sleep for one second and then continue the execution.
        std::thread::sleep(std::time::Duration::from_millis(1000));
    }

with

loop { }

I'm not even sure from where this loop is coming. Is it in the edge-mdns example?

The thing is, the program would never exit the block_on call, unless an error happens. You are not hitting this loop in the first place, so to say.

@ivmarkov

The device continues to reply to mDNS queries even after avahi-browse -a cannot discover ESP32-C3 anymore.

When I run ping mypc.local and we are in this state:

+  device IPv4 service-name                                         Secure Web Site      local

I get

PING mypc.local (192.168.178.126) 56(84) bytes of data.
64 bytes from my.router (192.168.178.126): icmp_seq=1 ttl=64 time=61.1 ms

rtt min/avg/max/mdev = 33.806/86.716/175.376/48.312 ms

So I can find the device and everything works perfectly.

After nearly 1 minute (it's not a precise time, it varies among tries), the outcome of avahi-browser -a becomes

-   device IPv4 service-name                                         Secure Web Site      local

and if I run ping mypc.local I get

ping: mypc.local: Name or service not known

The log still replies to that query from the ping command. Here's the log content:

I (271985) edge_mdns::io: Replying to mDNS query from [::ffff:192.168.178.57]:5353

I'm not even sure from where this loop is coming. Is it in the edge-mdns example?

The thing is, the program would never exit the block_on call, unless an error happens. You are not hitting this loop in the first place, so to say.

This is an attempt to solve the issue trying another solution, but it's now a typo. I've removed it from the code and pushed on the repository, thank you for catching it! Now, the code should be the same as the edge-mdns example.

ivmarkov commented 1 month ago

It does work for only one minute, because initially, the mDNS responder is doing this:

I (4255) edge_mdns::io: Broadcasting mDNS entry to 224.0.0.251:5353

After that it is not broadcasting anymore, because it is not supposed to broadcast anymore. The weird thing in your case is, that your avahi does not try to contact the mDNS responder on an IPv4 address, but only on ipv4- over-ipv6, which is very weird.

Anyway, I'll try to repro once I'm back.

And restarting avahi-daemon, but anything changed. The log and avahi-browse outputs remained the same of the previous message.

ivmarkov commented 4 weeks ago

The good news is, I can reproduce your problem now if I completely switch off ipv6 from the edge-mdns responder. Whether that's an Avahi configuration problem, or a responder issue - I need to research. Will look at it later today.

Luni-4 commented 4 weeks ago

This is great news! Reproducibility is always a good fact :laughing:

Thanks a lot!

ivmarkov commented 4 weeks ago

I added a fix on master where - regardless how we were contacted (on ipv4 or ipv6) we always broadcast on all available addresses where we have subscribed.

Just pull latest from master, use edge-mdns from master and try again.

Luni-4 commented 4 weeks ago

Thanks a lot! It is fixed now! I can ping mypc.local hostname from my laptop and the ESP32-C3 replies.

I've also performed further tests, though.

If I ping mpyc.local from Windows and macOS laptops, where both of them are connected to the same ESP32-C3 access point, everything works correctly.

When I ping the board from my Android smartphone, though, it cannot resolve the hostname. I can ping the IP directly instead. I'm using the connectbot app to run the ping command.

Here's the connectbot error:

ping mypc.local
ping: unknown host mypc.local

Here's the log where we cannot find the current smartphone IP, which is 192.168.178.115, but only the macOS and the gateway IPs:

Ok but... can you ping - from your phone - your WIndows and MacOS workstations on the .local domain?

ivmarkov commented 4 weeks ago

Can you run avahi-browse -a from your phone or better yet - avahi-resolve? Is your phone even configured to resolve addresses via mDNS lookup?

Yep, my Android version supports mDNS resolver https://source.android.com/docs/core/ota/modular-system/dns-resolver#mdns-local-resolution

I tried to run a server on my laptop which implements the mdns-sd crate and I can access to the main server page from my phone using the .local domain.

Moreover, if I run Service Browser I can find the service

But all I'm asking is if you can ping your desktop from the phone by using its .local suffixed name

ivmarkov commented 3 weeks ago

I really do not understand what you are trying to do. :)

You say:

"I can't ping (on the .local domain) the c3 from my phone"
Then I'm asking you to do exactly the same with your workstations - try to ping your workstations from your phone (and it SHOULD work because they run mDNS or else they themselves would not be able to ping the c3!; so if pinging your workstations from your phone ALSO does not work, it means that whatever mDNS your phone supports, it is not really integrated on the shell/OS/libc level)

... but then you are doing something completely different, which is to install an mdns-sd responder on your workstations, and a 3rd party mDNS browser on your phone? Not sure what that proves?

Also, the c3 does not "discover" your phone. It is your phone - which - because you installed this 3rd party "Service Browser" mDNS query-er - now discovers the c3. Not the other way around. And by the way the fact that the c3 is discovered by your phone means that you really should do this ping test with your workstations from the SSH console of your phone, as it (your phone that is) might just be broken on the SSH/command-line level w.r.t. mDNS-based hostname resolution.

@Luni-4 Argh OK, I should have read this link as to what your Android phone actually implements. They don't have an "mDNS responder", not even an "mDNS queryer" but implement the simplest of all hacks which is called a "one-shot query".

We don't (yet) support in edge-mdns replying to those types of queries. It might not be too difficult to add support for this.

But in any case, let me know what the outcome of trying to ping your workstations is as well.
