Manual backport of #99909

Fixes#99227

Customer Impact

Reported by customer via official support channel - they need same behavior on Linux, which works also on Windows and on .NET Framework.

Customers were facing issues when connecting from Linux to Windows when using the ProtectionLevel.EncryptAndSign value as NegotiateAuthenticationClientOptions.RequiredProtectionLevel. This scenario is common when connecting to WCF services hosted on Windows using WCF clients on Linux.

The bug affects primarily Android clients -- that is where the Managed NTLM implementation is used. We also allow the Managed NTLM as opt-in on macOS and Linux which would be likewise affected if the developer chooses to enable the System.Net.Security.UseManagedNtlm app context switch (which is rare).

Regression

No

Testing

Unit test was added. Validated by customer who reported the issue via official servicing channel.

Risk

Low; the modified code path is in platform specific code for a single authentication scheme. There is test coverage for the change.

…vers (dotnet#99909)
* Send the NegotiateSeal NTLM flag when client asked for
ProtectionLevel.EncryptAndSign.
Process the last handshake done message in NegotiateStream. In case of
SPNEGO protocol it may contain message integrity check. Additionally,
if the negotiated protocol is NTLM then we need to reset the encryption
key after the message integrity check is verified.
* Add test for the NegotiateSeal flag
* Fix the test
* Dummy commit
* Fix the new _remoteOk logic in NegotiateStream to fire only when HandshakeComplete.
If HandshakeComplete is not true, then the authentication blob will get processed with the normal flow.
* Fix the value of NegotiateSeal in the final authentication message of Managed NTLM

Manual backport of #99909

Fixes#99227

Customer Impact

Reported by customer via official support channel - they need same behavior on Linux, which works also on Windows and on .NET Framework.

Customers were facing issues when connecting from Linux to Windows when using the ProtectionLevel.EncryptAndSign value as NegotiateAuthenticationClientOptions.RequiredProtectionLevel. This scenario is common when connecting to WCF services hosted on Windows using WCF clients on Linux.

The bug affects primarily Android clients -- that is where the Managed NTLM implementation is used. We also allow the Managed NTLM as opt-in on macOS and Linux which would be likewise affected if the developer chooses to enable the System.Net.Security.UseManagedNtlm app context switch (which is rare).

Regression

No

Testing

Unit test was added. Validated by customer who reported the issue via official servicing channel.

Risk

Low; the modified code path is in platform specific code for a single authentication scheme. There is test coverage for the change.

…vers (dotnet#99909)
* Send the NegotiateSeal NTLM flag when client asked for
ProtectionLevel.EncryptAndSign.
Process the last handshake done message in NegotiateStream. In case of
SPNEGO protocol it may contain message integrity check. Additionally,
if the negotiated protocol is NTLM then we need to reset the encryption
key after the message integrity check is verified.
* Add test for the NegotiateSeal flag
* Fix the test
* Dummy commit
* Fix the new _remoteOk logic in NegotiateStream to fire only when HandshakeComplete.
If HandshakeComplete is not true, then the authentication blob will get processed with the normal flow.
* Fix the value of NegotiateSeal in the final authentication message of Managed NTLM

LGTM. Assuming this does not depend on any other 9.0 fixes.

This one is isolated. I would also like to backport the PR that fixed calculation of channel binding hash (#95898).
