esp8266 wdt reset broken

[dreamstruct]

hi Matej! Your aeslib is great and simplifies development But the problem of madness made me encounter In the test, the device will be inexplicably restarted Can you take the time to see what the problem is?

I used ESP8266 esp-01s arduino 1.8.7 ide

error msg :

Stack trace would help. This seems like being reset by watchdog timer when stucked in loop for too long.

Hello,

I've looked into the issue and also had some weird crashes on the go. However, without changing anything significant in the AESLib, there's new example that works for me at https://github.com/suculent/thinx-aes-lib/commit/825629c04bbee96f47bb74caab52b3ecc533cedf

Can you test whether it works for you, please? I've also added heap logging to see how much of your RAM is spent.

Regarding Your code, there may be a memory leak around lines:

String ReadBuffer = Serial.readString();
Serial.println("INPUT:" + String(ReadBuffer));

I 've used Serial.readStringUntil('\n'); instead, as this will exit upon entering whole cleartext and prevent looping and encryption in the middle of user entry.

Also, you don't need to convert String to String, that just adds memory fragmentation.

    String readBuffer = Serial.readStringUntil('\n'); // set 'newline' (LF) in the serial monitor
    Serial.println("INPUT:" + readBuffer);    
    sprintf(cleartext, "%s", readBuffer.c_str()); // must not exceed 255 bytes; may contain a newline at the end

hi Matej!

Thank you for taking the time to check the questions!

Thanks& regards!!!!

In more than 40 hours of testing, no better code could be found

So far, your code is best

However, there is still a bug, which is derived from (AES.CPP).

found that there are bugs in

void AES::padPlaintext(void in,byte out) { memcpy(out,in,size); <---------------------------------BUG for (int i = size-pad; i < size; i++){; out[i] = arr_pad[pad - 1]; } }

You can try the following

First: input long characters (about 150 or so)

Next: input the short character again, for example: 1

Cycle for a period of time, or several times

ESP8266 will be crash

Such questions drive me crazy

wdt reset

[suculent]

Yes, I've also chosen this code as a base as it is simple enough and well structured. However, there's been some development recently in other projects (see bottom of README), where we could find answers to our questions (especially AES.cpp which is NOT my code at all, see [https://github.com/spaniakos/AES/]).

I was in situaation where I've been stucked for 6 weeks with memory management. All it required were second exes of a real C++ programmer. I'm more like spread between high and low-level stuff from CX to assembler.

In latest Arduino/ESP8266 framework, it's suggested to use size_t instead of int, this might be an issue to be fixed.

The memcpy(out,in,size); depends on size global variable, which is assigned at 3 places:

• void AES::calc_size_n_pad(int p_size) – in 2 places:

void AES::calc_size_n_pad(int p_size){
  int s_of_p = p_size - 1;
  if ( s_of_p % N_BLOCK == 0){
      size = s_of_p;
  }else{
    size = s_of_p +  (N_BLOCK-(s_of_p % N_BLOCK));
  }
  pad = size - s_of_p;
}

• void AES::set_size(int sizel) – called by do_aes_decrypt where size = sizel;

[dreamstruct]

My development environment:

device : NodeMCU 1.0 (ESP-12E Module) esp8266 Community 2.4.0 esp8266 Community 2.4.1 esp8266 Community 2.4.2 All of these SDK versions will crash

[suculent]

I would need a code with your stacktrace. Can you paste it or make me a Collaborator on your project? Do you have ESP Exception Decoder installed?

To me, only 2.5.0-dev SDK crashes on network transport.

It looks like you're crashing in HardwareSerial.begin() while logging in AES.cpp. I'm using a Wemos D1 mini (4MB) and Wemos D1 Mini Pro (16MB) modules.

[suculent]

Note: I'm doing this to prevent padding crashes:

int paddedLen = b64len + (N_BLOCK - (b64len % N_BLOCK)) + 1;

The b64len is extended with number equal to amount of bytes, that need to be added to latest block to make it full (padded) N_BLOCK length. +1 is for the trailing '\0', because base64 encoded thing is a string, unlike the encrypted msg which could be just arbitrary bytes.

Maybe the +1 is missing in calc_size_n_pad where p_size - 1 seems to cut the '\0' C-string end stop.

[dreamstruct]

It was installed yesterday and cannot be used normally. Now I will study it I'm studying to study your lib, not a commercial project. If you have a good idea, I'd like to join I'm using PHP as a server to decode it

[suculent]

Your code seems to crash before AESLib.cpp, as the - strcpy is not in your log:

  strcpy(output, (char*)out2);
#ifdef AES_DEBUG
  Serial.println("- strcpy"); 
#endif

Also, the char out2[4*b64len]; does allocate a lot. I'd try to change it to 2*b64len. Unfortunately I cannot test on the hardware now, maybe later in the night.

[suculent]

Thanks, but we don't use PHP anymore.

And this is not my lib, it's only a wrapper to standard AES for ESP8266/Arduino (see history in readme).

I need this inside of http://thinx.cloud, if you're interested in something of a scale.

[suculent]

Please install the ESP Stacktrace Decoder, it will help. Try the complex example to see how many iterations will that survive (watch the free heap memory log line).

[suculent]

Welcome to the open source. I will definitely need this lib in future, but I do not depend on it yet. It needs someone else to test it (when it works for me, it means really nothing).

[suculent]

Sorry, I'm deleting off-topic messages. We should use another channel for one-to-one messages (Hangouts, Slack or whatever you prefer and is available both on Mobile and Desktop).

My English is not good, please don't mind my writing very slowly Don't worry, it's right to delete irrelevant content

[suculent]

My english is not a first language as well. Where are you from?

As I see, if the int msgLen = strlen(msg); would use sizeof(msg) instead, if would already include the +1 byte for '\0' c-string end stop resolving all future issues.

[suculent]

Also the byte cipher[2*b64len]; could be insufficient for long payloads (3 or 4 would solve it but keep in mind how much stack it takes).

But you may be able to use it only when connected to the VPN if you say, you can't Twitter from China. My friend does, but he probably uses the VPN as well.

I used the original AES.CPP There was no crash while trying to enter 1024->2048 bytes It is also tested by looping long and short characters Exciting!

  //stdout = freopen("/dev/ttyGS0","w",stdout);

You’re supposed to Fork my repository, replace the AES.cpp and AES.h, Commit and Push, create a Pull Request so anyone on the planet will benefit from what we’ve done. Forget credits, this is communism outside China, working great.

Don’t take credits for sticking open-source LEGO pieces together. 20 hours of google search is not a skill but failure. Once this will become part of Arduino framework, you’ll understand.

There are still some bugs in debugging that will be Shared with you if completed I didn't hear from you on twitter I thought you had fixed the mistake. I tried to contact you several times but received no reply Can you reply to my message on twitter? My twitter account is: @dreamstruct

I don't understand why you say that Even if I rewrite AESLib

originally I'll share with you when debugging is complete, but aes.cpp still has a lot of bugs I'm disappointed I want to delete the code that has been written

If you think google.com can solve a crash in 20 hours, that's wrong

Only beer and ubiquitous cigarette butts Of course, there must be perseverance

It's not a perfect solution, it just confuses more people, if they have the skills, if they can even solve it, if they don't have it it's torture

So it's not about helping people, and if businesses need to use the library, they'll think we're writing crap

I need to tell you something important

ESP Exception Decoder doesn't solve crash Because it's a waste of time

Closing this issue. If you have still problems, provide the stacktrace. If you have a solution, provide a PR. That’s how it works.
