Description

The partial shutdown on the non-blocking socket can result in NULL pointer references inside OpenSSL later. The attached patch avoids that.
At least on NetBSD this can be triggered very easily.

The patch is a workaround for correctly handling the double-shutdown. It might break clients that don't expect the silent shutdown though.

  • Status changed from New to Invalid
  • Patch available changed from Yes to No

That is not mentioned in the man page (http://www.openssl.org/docs/ssl/SSL_shutdown.html); and i don't see why this is a bug in lighttpd.

Btw: if you can easily reproduce NULL pointer dereferences, you should always provide the backtrace.
