Implement SMB streaming read using chunked READ requests
...
Test / test (push) Has been cancelled
Test / build (push) Has been cancelled
- Add file_id and read_chunk_size fields to SmbVfsFile
- Use Tree::open_file() to get file_id for reads
- Issue READ requests on each read() call (64KB chunks)
- Close file handle in Drop
Benefits:
- No memory overhead for large files
- Read-ahead caching possible
- Compatible with SMB2 protocol
All 229 tests pass.

Phase 2a: reuse_buf for CHANNEL_DATA
- channel.rs: Added reuse_buf to ExecProcess
- handle_channel_data(): Read directly into reuse buffer
Phase 2b: read_buf for stdout/stderr
- channel.rs: Added read_buf to ExecProcess
- poll_exec_stdout_and_client(): Use read_buf for all reads
Phase 2c: AES-GCM padding optimization
- cipher.rs: Removed padding .to_vec() in AES-GCM decrypt
stdin fix: All exec commands use interactive process
- channel.rs: Removed conditional rsync/SCP detection
- All exec commands now use handle_interactive_exec()
- Fixes cat/grep/sed stdin support (small files working)
AES-GCM improvements:
- cipher.rs: Added CipherMode enum (AES-GCM vs AES-CTR)
- cipher.rs: AES-256 key derivation (32 bytes)
- cipher.rs: Nonce format follows OpenSSH inc_iv()
- kex.rs: Added aes256-gcm@openssh.com to algorithms

Implement Phase 1 AES-GCM packet processing: AEAD encryption/decryption
...
Test / test (push) Has been cancelled
Test / build (push) Has been cancelled
Phase 1 complete implementation:
- AES-GCM AEAD encryption (EncryptedPacket::new)
- AES-GCM AEAD decryption (EncryptedPacket::read)
- AES-GCM packet structure: packet_length plaintext + ciphertext + 16-byte tag
- AES-GCM nonce: sequence_number (4 bytes -> 12 bytes)
- AES-CTR fallback preserved (MtE mode)
Key differences AES-GCM vs AES-CTR:
- AES-GCM: packet_length is plaintext (as AAD)
- AES-CTR: packet_length is encrypted
- AES-GCM: 16-byte GCM tag (no separate MAC)
- AES-CTR: 32-byte HMAC-SHA256 MAC
Performance improvement:
- AES-GCM: encrypt+authenticate in one step (AEAD)
- AES-CTR: MAC-then-Encrypt (2 steps)
Testing:
- OpenSSH client negotiated aes256-gcm@openssh.com
- cipher_mode set to AesGcm successfully
- Next: full SSH connection test

Test / test (push) Has been cancelled
Root cause: handle_channel_data processed only ONE SFTP packet per call,
leaving remaining batched packets stuck in the buffer. Client waited for
READ responses while server waited for more data — deadlock after ~3.1MB.
Fix:
- sftp_handler.rs: fix SSH_FXP_VERSION format (remove uint32 extension_count)
- sftp_handler.rs: fix handle_open error mapping (.ok() → build_status_from_io_error)
- channel.rs: batch-process ALL complete SFTP packets from buffer in loop
- channel.rs: add pending_packets VecDeque for multi-response queuing
- channel.rs: chain WINDOW_ADJUST + SFTP response when window is low
- channel.rs: add adjust_remote_window() for client WINDOW_ADJUST
- server.rs: drain pending_packets after each CHANNEL_DATA handler

Phase 16.1: Fix SCP stdin timeout (final analysis: abandon SCP legacy, recommend rsync)
...
Test / test (push) Has been cancelled
Test / build (push) Has been cancelled
修改内容：
- stdin timeout: 从500 iterations (5s) 改到3000 (30s)
- max_poll_iterations: 从1000改到5000 (50s)
- SCP完全禁用stdin timeout (is_scp_command检测)
测试结果：
- ❌ SCP 20MB失败 (只传输12MB, 400 KB/s)
- ✅ rsync 20MB成功 (MD5一致, 780 KB/s)
- 结论：SCP legacy protocol效率低，放弃SCP，推荐rsync
决策：方案3 - 放弃SCP legacy，推荐rsync (见phase16_1_scp_analysis.md)
下一步：Phase 16.2 - 性能优化 (提升780 KB/s到21-36 MB/s)

Phase 4: Implement SSH packet size limit (maxpack - 1024)
...
Test / test (push) Has been cancelled
Test / build (push) Has been cancelled
- Add maxpack field to SftpHandler structure
- Modify SftpHandler::new() to accept maxpack parameter
- Limit SSH_FXP_READ data size to maxpack - 1024 bytes (OpenSSH style)
- Get maxpack from Channel.remote_maxpacket
Changes:
- sftp_handler.rs: SftpHandler struct + new() + handle_read()
- channel.rs: Pass remote_maxpacket to SftpHandler::new()
Reference: OpenSSH sftp-server.c: process_read()
- Limit: maxpacket - 1024 bytes
- Prevent packet size violation
Test status: 5MB upload still incomplete (2.0MB)
- Issue may require additional debugging
- Upload direction may also need maxpack limit
