🌐 Web query:

SSL_RECEIVED_SHUTDOWN WolfSSL OpenSSL constant definition

💡 Result:

Short answer:

  • OpenSSL: SSL_SENT_SHUTDOWN = 0x01 (value 1), SSL_RECEIVED_SHUTDOWN = 0x02 (value 2); they are shutdown-state bitflags (sent = close_notify sent, received = close_notify received). [1]

  • wolfSSL: wolfSSL_get_shutdown() returns 1 for SSL_SENT_SHUTDOWN and 2 for SSL_RECEIVED_SHUTDOWN (same numeric meanings). [2]

Sources:
[1] OpenSSL manpage SSL_set_shutdown / SSL_shutdown.
[2] wolfSSL documentation (wolfSSL_shutdown / wolfSSL_get_shutdown).

SSL_RECEIVED_SHUTDOWN may not be available in all WolfSSL builds.

The code uses SSL_RECEIVED_SHUTDOWN without verifying it's defined. While WolfSSL does support this constant when built with OpenSSL compatibility (--enable-opensslextra or --enable-opensslall), many standard distributions omit these flags. This will cause compilation errors on incompatible WolfSSL installations.

Either:

  • Add a CMake check in FindWolfSSL.cmake to verify OpenSSL compatibility mode is enabled, or
  • Provide a fallback definition (e.g., #if !defined(SSL_RECEIVED_SHUTDOWN) #defineSSL_RECEIVED_SHUTDOWN 0x02#endif``)
🤖 Prompt for AI Agents 
In `@src/wolfssl/src/wolfssl_stream.cpp` around lines 424 - 439, The code uses
SSL_RECEIVED_SHUTDOWN in the wolfSSL_stream.cpp path that checks
wolfSSL_get_shutdown(ssl_) & SSL_RECEIVED_SHUTDOWN, but that constant may be
missing in non-OpenSSL-compat WolfSSL builds; update the project to handle both
cases by either adding a CMake/FindWolfSSL check to assert OpenSSL-compat mode
is present or add a local fallback macro so compilation succeeds (e.g., detect
if SSL_RECEIVED_SHUTDOWN is undefined and define a sensible fallback) and keep
the existing logic that calls wolfSSL_get_shutdown(ssl_) unchanged; reference
SSL_RECEIVED_SHUTDOWN and wolfSSL_get_shutdown(ssl_) when implementing the check
or defining the fallback.
