Fixes esp8266#8079 Because WiFiClientSecure inherits WiFiClient, and WiFiClientSecureCtx also inherits WiFiClient, they both end up in the list of TCP connections that are used for WiFiClient::stopAllExcept(). This would cause the underlying SSL connection to be closed whenever you attempted to stopAllExcept(WiFiClientSecure) Fix by adding a "_owner" pointer in the WiFiClient object which points to nullptr (default case) or to the associated upper-layer connection. When stopping all connections except one, only look at the uppermost connections.

@d-a-v, I think I need to reverse the sense here and look at the lowest-level, not uppermost one. So hold off on any review or merge, please. |
Because there may be multiple copies of the WiFiClientSecure, but only a single WiFiClientCtx, use the Ctx to check for relatedness on connections. This will avoid closing SSL connections that were assignment copies.

Okay, good to go @d-a-v. Logic reversed and tested locally. |

Fixes #8079
Because WiFiClientSecure inherits WiFiClient, and WiFiClientSecureCtx also
inherits WiFiClient, they both end up in the list of TCP connections that
are used for WiFiClient::stopAllExcept(). This would cause the underlying
SSL connection to be closed whenever you attempted to
stopAllExcept(WiFiClientSecure)
Fix by adding a "_owner" pointer in the WiFiClient object which points to
nullptr (default case) or to the associated upper-layer connection.
When stopping all connections except one, only look at the uppermost
connections.
