From 67051f2c111cc6a72755c3f0f071e0cc9b6012a1 Mon Sep 17 00:00:00 2001 From: Junyi Ou Date: Mon, 22 Jun 2026 22:47:33 -0400 Subject: [PATCH 1/2] feat(winrm): spec-correct HTTP/HTTPS transport with connection-oriented auth Over plain HTTP, SSPI message sealing is used (application/HTTP-SPNEGO-session- encrypted). Over HTTPS, TLS provides confidentiality so the body is sent plain (application/soap+xml) and authentication is connection-oriented (RFC 4559): the connection is authenticated once during the handshake (the first operation rides the SPNEGO challenge legs) and every subsequent operation reuses that authenticated connection. requires_sspi_sealing() is therefore true only for plain HTTP. Key points: - SSPI INTEGRITY (sign) is requested unconditionally; CONFIDENTIALITY (seal) only when sealing. INTEGRITY over HTTPS lets the server trust the connection and produces the NTLM MIC / SPNEGO mechListMIC. - EPA channel binding (tls-server-end-point): learned from the server cert after a 401 and applied on a restarted auth sequence. - AlreadyComplete is handled consistently across all four transports (tokio direct, gateway, sync, web). - Fail fast on terminal auth rejection (401 -> PwshCoreError::Auth), try_join! so a failed handshake short-circuits, and the non-interactive client exits non-zero on failure / clean on success (command_completed is authoritative). - Basic over plain HTTP is refused unless --http-insecure is given. --- Cargo.lock | 1 + crates/ironposh-async/src/connection.rs | 18 +- crates/ironposh-async/src/session.rs | 1 + .../ironposh-async/src/session_serial/core.rs | 1 + crates/ironposh-client-core/Cargo.toml | 1 + .../src/connector/auth_sequence.rs | 53 +++-- .../src/connector/authenticator.rs | 72 ++++++- .../src/connector/connection_pool.rs | 190 +++++++++++++++++- .../src/connector/http.rs | 5 + .../ironposh-client-core/src/connector/mod.rs | 11 +- .../ironposh-client-sync/src/http_client.rs | 33 ++- crates/ironposh-client-tokio/src/config.rs | 12 ++ .../src/gateway_http_client.rs | 22 ++ .../ironposh-client-tokio/src/http_client.rs | 38 +++- crates/ironposh-client-tokio/src/main.rs | 91 ++++++++- .../ironposh-test-support/src/fake_server.rs | 1 + crates/ironposh-web/src/http_client.rs | 24 ++- crates/ironposh-web/src/http_convert.rs | 1 + crates/ironposh-web/src/ws_http_decoder.rs | 4 + 19 files changed, 534 insertions(+), 45 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index 29e5a0a..64a400e 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1555,6 +1555,7 @@ dependencies = [ "regex", "rsa 0.9.9", "serde", + "sha2", "sspi", "thiserror 2.0.17", "tokio", diff --git a/crates/ironposh-async/src/connection.rs b/crates/ironposh-async/src/connection.rs index 6e7e99d..240b699 100644 --- a/crates/ironposh-async/src/connection.rs +++ b/crates/ironposh-async/src/connection.rs @@ -1,7 +1,7 @@ use std::sync::Arc; use anyhow::Context; -use futures::{SinkExt, StreamExt, channel::mpsc, join}; +use futures::{SinkExt, StreamExt, channel::mpsc, join, try_join}; use ironposh_client_core::{ connector::{ Connector, ConnectorStepResult, UserOperation, WinRmConfig, active_session::UserEvent, @@ -302,9 +302,13 @@ where ); let joined_task = async move { - let res = join!(active_session_task, multiplex_pipeline_task); + // try_join!
