e0e145e277 fix(ssh): Re-add uint32 prefix for shared secret K in exchange hash and key derivation
Some checks failed
Test / test (push) Has been cancelled
Details
Test / build (push) Has been cancelled
Details 
OpenSSH sshbuf_put_bignum2_bytes() writes uint32(len) + mpint_data
to the buffer (confirmed from sshbuf-getput-basic.c line 569). Both
kex_gen_hash() via sshbuf_putb() and kex_derive_keys() via
ssh_digest_update_buffer() consume the full buffer including the uint32
prefix.

Fixes 'incorrect signature' error on OpenSSH 10.2.

a4493b8528 perf(ssh): Phase 3 BufferPool - preallocate Vec in hot paths
Some checks failed
Test / test (push) Has been cancelled
Details
Test / build (push) Has been cancelled
Details 
Phase 3: Preallocate Vec with capacity to reduce allocations

channel.rs:
- poll_exec_stdout_and_client(): Vec::with_capacity(channels * 3 + 1)
- poll_exec_stdout_with_fds(): Vec::with_capacity(channels * 2)

cipher.rs:
- AES-CTR decrypt: payload Vec::with_capacity(payload_length)

Performance improvement:
- ~25% total improvement (Phase 1-3 cumulative)
- 100MB transfer: 1 second (~100 MB/s)
- 140x improvement from initial 712 KB/s

bd89152e81 feat(ssh): Optimize SSH performance Phase 1-2c + stdin fix
Some checks failed
Test / test (push) Has been cancelled
Details
Test / build (push) Has been cancelled
Details 
Phase 1: take_payload() optimization
- cipher.rs: Added take_payload() to EncryptedPacket
- server.rs: Use take_payload() to avoid .to_vec() copy

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

Performance: ~21% improvement for small files
Test: 158 passed, 0 failed
Limitation: Large files (>10MB) not working yet (poll loop issue)

1650708ac7 Implement Phase 1 AES-GCM packet processing: AEAD encryption/decryption
Some checks failed
Test / test (push) Has been cancelled
Details
Test / build (push) Has been cancelled
Details 
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

3575ab7e66 Implement Phase 1: AES-256-GCM algorithm negotiation and cipher mode setting
Some checks failed
Test / test (push) Has been cancelled
Details
Test / build (push) Has been cancelled
Details 
Performance optimization Phase 1 implementation:
- Add aes-gcm crate dependency (v0.10)
- Add CipherMode enum (AesCtr vs AesGcm)
- Modify KEX algorithm negotiation: add aes256-gcm@openssh.com
- Dynamic cipher mode setting based on KEX result
- Fix HMAC trait conflict with fully-qualified syntax

Strategy: Conservative approach
- Support AES-GCM algorithm negotiation (OpenSSH compatible)
- Dynamic cipher mode setting
- AES-CTR fallback preserved (packet processing unchanged)

Next steps:
- Test OpenSSH client AES-GCM negotiation
- Implement AES-GCM packet processing if needed
- Continue to Phase 4 (parallel encryption)

83fb0de78a Fix 5MB SFTP download hang: batch process SFTP packets + WINDOW_ADJUST chaining
Some checks failed
Test / test (push) Has been cancelled
Details
Test / build (push) Has been cancelled
Details 
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

Verified: 5MB upload + download with matching MD5

Test / build (push) Has been cancelled
Details 
In-process RsyncHandler couldn't match openrsync protocol 29 flow

same approach as SCP handler.

All file sizes (5MB, 20MB, 50MB, 100MB) successfully transferred with
MD5 verification passing. Transfer speed ~712 KB/s limited by
AES-256-CTR encryption overhead.
