we tried to update to Mongoose 6.9 and can't get further than the TLS handshake.
I have compiled your example "simplest_web_server_ssl" to except an error in our wrapper library, but with the running example we get the same error.
I tested it with cURL in the following versions / combinations:
curl 7.55.0 (x86_64-w64-mingw32) libcurl/7.55.0 OpenSSL/1.0.2l zlib/1.2.11 libssh2/1.8.0 nghttp2/1.23.1 curl 7.56.0 (i386-pc-win32) libcurl/7.56.0 OpenSSL/1.0.2e zlib/1.2.8
And tried compiling mongoose and the example with the following OpenSSL versions:
OpenSSL 1.0.2f 28 Jan 2016 OpenSSL 1.0.2l 25 May 2017
The error cURL gives is always:
$ curl -v -k https://127.0.0.1:8443 * Rebuilt URL to: https://127.0.0.1:8443/ * timeout on name lookup is not supported * Trying 127.0.0.1... * TCP_NODELAY set % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0* Connected to 127.0.0.1 (127.0.0.1) port 8443 (#0) * ALPN, offering h2 * ALPN, offering http/1.1 * Cipher selection: ALL:!EXPORT:!EXPORT40:!EXPORT56:!aNULL:!LOW:!RC4:@STRENGTH * successfully set certificate verify locations: * CAfile: C:/Program Files/Git/mingw64/ssl/certs/ca-bundle.crt CApath: none * TLSv1.2 (OUT), TLS header, Certificate Status (22): } [5 bytes data] * TLSv1.2 (OUT), TLS handshake, Client hello (1): } [512 bytes data] * OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to 127.0.0.1:8443 * stopped the pause stream! 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0 * Closing connection 0 curl: (35) OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to 127.0.0.1:8443
Nevermind if we use our self-sigend certificate or that one that is deployed with your example.
We tried to debug the error and came to mongoose.c:4341
res = server_side ? SSL_accept(ctx->ssl) : SSL_connect(ctx->ssl);
Which has server_side = 1 so uses the SSL_accept function. After that it triggers the SSL error.
Can you help out, what the problem is and how we can get this working again? Are there any other informations i could provide which could help out?
It worked before with mongoose version 6.6.
