Inconsistent behavior in SslStream.AuthenticateAsClient across win/linux #81590
Description
Description
On .NET 7.0, SslStream.AuthenticateAsClient behaves differently on Windows and Linux. When TargetHost is set for the SslClientAuthenticationOptions parameter, in some cases on Linux it will lead to the connection not establishing successfully, while it does on Windows.
While this appears to be host specific and is dependent on the parameters to AuthenticateAsClient, the fact that the very same code does not function the same across OS is problematic, leading to a lot of wasted time.
On Linux, you will simply get a connection reset:
Unhandled exception. System.IO.IOException: Unable to read data from the transport connection: Connection reset by peer.
---> System.Net.Sockets.SocketException (104): Connection reset by peer

Reproduction Steps
Run this code across both Windows and Linux:
using System.Net.Security;
using System.Net.Sockets;
public class Program
{
public static void Main()
{
TcpClient client = new TcpClient("143.166.83.22", 443);
SslStream sslStream = new SslStream(client.GetStream(), false);
sslStream.AuthenticateAsClient(new SslClientAuthenticationOptions(){TargetHost = "143.166.83.22",RemoteCertificateValidationCallback = (sender, x509Certificate, chain, errors) => true});
}
}Expected behavior
As seen on Windows: A connection is established.
Actual behavior
As seen on Linux: Connection is reset:
Unhandled exception. System.IO.IOException: Unable to read data from the transport connection: Connection reset by peer.

Regression?
No response
Known Workarounds
Not setting TargetHost can help in some cases.
