Hi~

Previous, I used wolfssl-2.2.2 for supporting TLS with blocking IO. But exceptionally Infinite loop occurs in trying to
wolfssl_connect()

#0 0x1007e454 in DoApplicationData ()
No symbol table info available.
0000001 0x1007faac in ProcessReply ()
No symbol table info available.
0000002 0x10069ba4 in WolfSSL_connect ()
No symbol table info available.

Not to escape wolfssl_connect(). I don't know why it occurs and method for resolving it.

I upgraded lib to latest release version(2.8.0) also used nonblocking IO only to client-side based on example/client/client.c for handling problem but I see an error (-223 which means WANT_READ) in ssl_accept() after swching to nonblocking IO.

I attached snapshot to both client and server-side when wolfssl-debugging-on.

Please let me know method for solving it.

Thank you for reading it.


Thanks,
Raphael

hi~

I already used wolfssl 2-2-2 in mips64 n32. Sometime there is problem that infinite loop occurred in doing SSL_connect.
before attaching to ssl object , I set RCVTIME in socket descriptor.

frame #1 to #2 #1 to #2 ... 

#0  0x1007e58c in DoApplicationData ()
#1  0x1007faac in ProcessReply ()
#2  0x10069ba4 in wolfSSL_connect ()


I spent much time to try to resolve it , but there is no issue. that's why I want to upgrade to latest one.
but wolfssl supported mips64 but don't do n32(mabi=n32)

below are message in make

Let me know about handing this situation.
