Hi Marte,

I checked the address family and the address length but I don't see any potential issues.

Now I am using getaddrinfo() to properly point the sockaddr and ensure there is no issue in address family and length. Below given my modification wrt to those change.

#if defined(CONFIG_NET_SOCKETS_SOCKOPT_TLS)
  struct addrinfo hints = {
      .ai_family   = PF_INET6,
      .ai_socktype = SOCK_STREAM,
      .ai_protocol = IPPROTO_TLS_1_2,
      .ai_flags    = AI_NUMERICSERV | AI_NUMERICHOST | AI_V4MAPPED | AI_ALL};
  ret = getaddrinfo(SERVER_ADDR6, "443", &hints, &res);
#else
  struct addrinfo hints = {
      .ai_family   = AF_INET,
      .ai_socktype = SOCK_STREAM,
      .ai_protocol = IPPROTO_TCP,
      .ai_flags    = AI_NUMERICSERV | AI_NUMERICHOST | AI_V4MAPPED | AI_ALL};
  ret   = getaddrinfo(SERVER_ADDR6, "80", &hints, &res);
#endif

Still the result is same.

Hi,

Error 22 is invalid argument, so most likely, one or more of the arguments you are giving is incorrect. You should check that the address length is valid for the address family and that the address family is correct.

Best regards,
Marte

Hi Marte,

Any clue on TLS socket connection returns error -22?

I took a look at the nRF9160 DK HTTPS Client sample and addd the missing config options but that also doesn't help to solve that error.

Should I have to try anything else.

Regards

Hi,

[quote user="vipin das"]You can share me any proper TLS sample where I can take a look and get inspired to make my application working [/quote]

The examples you used previously, echo_client and http_client, have support for enabling TLS by setting OVERLAY_CONFIG to overlay-tls.conf. Other than that, we also have support for Mbed TLS in several nRF9160 samples, such as HTTPS Client and Simple MQTT, and we have Crypto: PSA TLS that shows how to do TLS handshakes.

Best regards,

Marte

Hi Marte,

I have added the tis_credential_add() to add the downloaded server certificate to authenticate the remote server. After adding that connect error is -22 (EINVAL).

Hi Marte,

Yes you are right. My config related to TLS shared below.

#Socket settings
CONFIG_NET_SOCKETS_SOCKOPT_TLS=y
CONFIG_POSIX_MAX_FDS=8
CONFIG_NET_SOCKETS_TLS_MAX_CONTEXTS=10

#MBEDTLS and security configuration 
CONFIG_MBEDTLS_CFG_FILE="config-tls-generic.h"
CONFIG_OPENTHREAD_MBEDTLS_CHOICE=y
CONFIG_MBEDTLS_TLS_VERSION_1_2=y
CONFIG_MBEDTLS_TLS_LIBRARY=y
CONFIG_MBEDTLS_SSL_PROTO_TLS1_2=y

# TLS configuration
CONFIG_MBEDTLS=y
CONFIG_MBEDTLS_BUILTIN=y
CONFIG_MBEDTLS_ENABLE_HEAP=y
CONFIG_MBEDTLS_HEAP_SIZE=8192
CONFIG_MBEDTLS_ENTROPY_ENABLED=y
# certificate must fit into one message, fragmenting is not supported
CONFIG_MBEDTLS_SSL_MAX_CONTENT_LEN=8192

#Credentials
CONFIG_TLS_CREDENTIALS=y
CONFIG_TLS_MAX_CREDENTIALS_NUMBER=4

No I don't think I have any functionality for TLS at the moment.

Please consider me a novice user in networking topics. This is 1st time I am working on TLS socket connection. I just followed some of the existing samples and few discussions. I don't really understand about the certification and private key that you mentioned above. I have created the ca_cert.der for the server and it looks similar like below.

"-----BEGIN CERTIFICATE-----\n"
"----------------------------------------------------------------\n"
"----------------------------------------------------------------\n"
"----------------------------------------------------------------\n"
"-----END CERTIFICATE-----\n"
"-----BEGIN CERTIFICATE-----\n"
"----------------------------------------------------------------\n"
"----------------------------------------------------------------\n"
"----------------------------------------------------------------\n"
"-----END CERTIFICATE-----\n"
"-----BEGIN CERTIFICATE-----\n"
"----------------------------------------------------------------\n"
"----------------------------------------------------------------\n"
"----------------------------------------------------------------\n"
"-----END CERTIFICATE-----\n"

You can share me any proper TLS sample where I can take a look and get inspired to make my application working

Regards

Marte Myrvold — Tue, 31 Jan 2023 09:34:31 GMT

Hi,

So your example is unchanged other than enabling CONFIG_NET_SOCKETS_SOCKOPT_TLS?

Is mbedTLS (CONFIG_MBEDTLS) enabled? Do you have any functionality for TLS? Are you using the correct credentials (certification and private key)?

Best regards,

Marte

RE: Adaption to TCP+TLS on top of OpenThread.

vipin das — Tue, 31 Jan 2023 09:03:59 GMT

Hi Marte,

Yes this is the same log after TCP got worked. For this log I just enabled the CONFIG_NET_SOCKETS_SOCKOPT_TLS=y. Don't get confuse with that particular log. That is something I added.

ret = connect(*sock, addr, addr_len);
  if (ret < 0) {
    LOG_ERR("Cannot connect to %s remote (%d)", family == AF_INET ? "IPv4" : "IPv6", -errno);
    ret = -errno;
  }

This time it fails at this connect to TLS socket but socket creation is success(socket(family, SOCK_STREAM, IPPROTO_TLS_1_2)).

Hi Marte,

I am able to send/receive RPC request/response to our server using TCP socket connection.

Now we can focus on TLS. Could you please help me to trace out the issue with TLS socket.

For that I am sharing latest log for your reference.

Hi,

Yes I have restarted the my Mac after the installation. I am using a dongle.

Thanks

Hi,

Did you restart your computer after installing Wireshark and configuring the sniffer? I have seen several cases where the sniffer does not show up until after a restart. Are you using a dongle or DK as sniffer?

Best regards,

Marte

Hi Marte,

I was trying to setup nRF sniffer tool as per the page: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_sniffer_802154%2FUG%2Fsniffer_802154%2Finstalling_sniffer_802154.html. I followed each steps and copied the nrf802154_sniffer.py into Wireshark(3.6.11) ext cap folder. Even I verified the python script

das@Vipins-MBP extcap % python3 nrf802154_sniffer.py --extcap-interfaces                         
extcap {version=0.7.2}{help=https://github.com/NordicSemiconductor/nRF-Sniffer-for-802.15.4}{display=nRF Sniffer for 802.15.4}
interface {value=/dev/cu.usbmodemEC108B497C3D1}{display=nRF Sniffer for 802.15.4}
control {number=6}{type=button}{role=logger}{display=Log}{tooltip=Show capture log}

But nRF Sniffer for 802.15.4 interface is not detecting on the Wireshark. Did I miss any thing here.

I looked many other discussion but nothing helps in my case. Even I tried with 2 different Wireshark versions(3.6 & 4.0).

Any clue?

Regards

Hi Marte,

Thank you.

I fixed the Bad request error also. The problem got solved after removing req.content_type_value="application/json;charset=UTF-8".

But now I am getting Response status Internal Server Error(500). I am sharing the log for the new error.

We have checked the logs on the server as well but because of the Bad request we could not catch much information. Hopefully I will get new dongle today to setup sniffer. Will have more update on the issue by Monday.

Hi,

[quote user="vipin das"]I am getting response(Bad Request) from server as follows. "http_client: server_response_cb: Response status Bad Request". Do you think I should do anything in the configuration. Below is my code snippet for http header formation. Could you please tell what is wrong here with my request. [/quote]

Please share the complete log of this.

Have you checked the logs on the server?

[quote user="vipin das"]Could you please tell me any config option to enable the http_client log to see the http request(header + payload) that I send to http server. Soon I will setup the sniffer for 802.15.4, hope that helps bit more right? [/quote]

Set the log level to debug, i.e CONFIG_NET_HTTP_LOG_LEVEL_DBG=y.

The sniffer log might help with figuring out what is happening, yes.

[quote user="vipin das"]After this I wanted to use TLS socket for a secure communication.[/quote]

Let us focus on getting TCP to work first, before focusing on TLS.

Hi Marte,

Finally I figured it out the reason for the above mentioned issue. OpenThread's TCP stack interferes with Zephyr's stack. Jonathan from OpenThread gave a hint on the problem and disabling the config solves the issue.

But I might need your support on figuring out some other issues.

I am getting response(Bad Request) from server as follows. "http_client: server_response_cb: Response status Bad Request". Do you think I should do anything in the configuration. Below is my code snippet for http header formation. Could you please tell what is wrong here with my request.

char* fields[]         = {"Host:mainnet.incubed.net", "User-Agent: openthread https for in3", NULL};
    req.header_fields      = fields;
    req.optional_headers   = fields;
    req.content_type_value = "application/json";
    req.method             = HTTP_POST;
    req.url                = "/";
    req.host               = SERVER_ADDR6;
    req.protocol           = "HTTP/1.1";

    ret                    = http_client_req(sock6, &req, timeout, "IPv6 POST");

Could you please tell me any config option to enable the http_client log to see the http request(header + payload) that I send to http server. Soon I will setup the sniffer for 802.15.4, hope that helps bit more right?

Hi Marte,

Thank you.

I am not sure how quickly I can setup the sniffer for 802.15.4 as I don't have spare dongle with me. I have only one spare nRF5340 DK. I think I cannot setup sniffer on that. But let me see how fast I can set it up.Do you have any other thoughts on this issue or something I can try.

Currently I am using the default network key for my thread network.

So far I didn't check the logs on the server side. But can check the logs tomorrow.

Regards

Hi,

115 is ENETDOWN (network is down) and 116 is ETIMEDOUT (connection timed out).

Can you set up an 802.15.4 sniffer and collect a sniffer log of when you try to set up TCP socket? Make sure to use the same Thread nwk key as the default one in the samples, or share your nwk key here.

Are you able to collect logs from the server? If so, are you able to see if anything is happening there?

Best regards,

Marte

Hi Marte,

Sorry to ask on this issue again as I am really blocked because of this. I know you are also busy with lot of other issues.

I am ready to try any suggestions you make to resolve this. Do you think " net_config: Network initialisation failed (-115)" has anything to do with this error " Cannot connect to IPv6 remote (-116)".

Regards

Hi Marte,

Thanks. It is very much similar as in the http_client.

connect_socket:

static int connect_socket(sa_family_t family, const char* server, int port,
                          int* sock, struct sockaddr* addr, socklen_t addr_len) {
  int ret;

  ret = setup_socket(family, server, port, sock, addr, addr_len);
  if (ret < 0 || *sock < 0) {
    LOG_ERR("Setup socket Failed");
    return -1;
  }

  ret = connect(*sock, addr, addr_len);
  if (ret < 0) {
    LOG_ERR("Cannot connect to %s remote (%d)", family == AF_INET ? "IPv4" : "IPv6", -errno);
    ret = -errno;
  }
  return ret;
}

setup_socket:

static int setup_socket(sa_family_t family, const char* server, int port, int* sock, struct sockaddr* addr, socklen_t addr_len) {
  const char* family_str = family == AF_INET ? "IPv4" : "IPv6";
  int         ret        = 0;

  memset(addr, 0, addr_len);

  if (family == AF_INET) {
    net_sin(addr)->sin_family = AF_INET;
    net_sin(addr)->sin_port   = htons(port);
    inet_pton(family, server, &net_sin(addr)->sin_addr);
  }
  else {
    net_sin6(addr)->sin6_family = AF_INET6;
    net_sin6(addr)->sin6_port   = htons(port);
    inet_pton(AF_INET6, server, &net_sin6(addr)->sin6_addr);
    LOG_DBG("Setup socket info: Server address: %s", server);
  }

#if defined(CONFIG_NET_SOCKETS_SOCKOPT_TLS)
  sec_tag_t sec_tag_list[] = {CA_CERTIFICATE_TAG};

  *sock = socket(family, SOCK_STREAM, IPPROTO_TLS_1_2);
  if (*sock >= 0) {
    ret = setsockopt(*sock, SOL_TLS, TLS_SEC_TAG_LIST, sec_tag_list, sizeof(sec_tag_list));
    if (ret < 0) {
      LOG_ERR("Failed to set %s secure option (%d)", family_str, -errno);
      ret = -errno;
    }

    ret = setsockopt(*sock, SOL_TLS, TLS_HOSTNAME, TLS_PEER_HOSTNAME, sizeof(TLS_PEER_HOSTNAME));
    if (ret < 0) {
      LOG_ERR("Failed to set %s TLS_HOSTNAME "
              "option (%d)",
              family_str, -errno);
      ret = -errno;
    }
  }
#else
  *sock    = socket(family, SOCK_STREAM, IPPROTO_TCP);
#endif

  if (*sock < 0) {
    LOG_ERR("Failed to create %s HTTP socket (%d)", family_str, -errno);
  }
  return ret;
}

Initially I wanted to see I am able to connect to TCP socket later I I will try to make TLS work. So please take a look at below given logs:

I have shared almost complete log from one power cycle. From the above given logs, I noticed two err things which I didn't understand well why?

[00:00:30.336,486] <err> net_config: Timeout while waiting network interface
[00:00:30.336,517] <err> net_config: Network initialization failed (-115)

[00:00:37.288,848] <err> http_client: Failed to connect to socket

What it means with error code -116: Stale NFS file handle?

Hi,

There are some problems with setting up the socket. First it fails to connect to IPv6 remote due to the socket not existing, but afterwards you are unable to open sockets because there are too many open sockets. Can you share the code where you connect and open the socket? Is it similar to connect_socket() and setup_socket() in http_client?

Best regards,

Marte

Hi Marte,

Register public certificate issue is solved as I understood tls_credential_add() is not needed in my case as the public certificate is already available.

Hi,

I see that you are getting this in your log:

Failed to register public certificate: -17

Error 17 is EEXIST, which means that the file exists. This might be caused by calling tls_credential_add() several places with the same sec_tag and type. I see that you are calling it in send_https_post(). Does it work the first time, and then fails the following times, or does it fail from the beginning?

Best regards,

Marte
