68472e0fb7 Fix all remaining test failures
Some checks failed
Test / test (push) Has been cancelled
Test / build (push) Has been cancelled
- archive::metadata: add failed_files to test_extract_result
- archive::tests: use TempDir for validate_extraction_path test
- provider::sqlite: fix db path using CARGO_MANIFEST_DIR/../data/auth.sqlite
- ssh_server::cipher: use AES-128 key (16 bytes) in test
- ssh_server::kex_complete: set kexinit payloads in test
- ssh_server::rsync_handler: fix file list flags (use 1, not 0)
- ssh_server::sftp_handler: expect SSH_FXP_VERSION at byte 4 (after length prefix)

All 135 tests now pass

581c78469c OpenSSH client源码验证:发现padding bytes差异
Some checks failed
Test / test (push) Has been cancelled
Test / build (push) Has been cancelled
深度分析OpenSSH packet processing:

关键发现:
 ssh_packet_read_poll2_mux(): incoming_packet存储padding_length + type + payload + padding
 sshbuf_get_u8()消耗padding_length和type后,剩余payload + padding
 kex_input_kexinit(): sshpkt_ptr()返回payload + padding(从cookie开始)
 kex->peer存储:payload fields + padding(不包括type byte)

差异:
- OpenSSH kex->peer包括padding bytes
- 我们client_kexinit_payload不包括padding bytes

测试padding fix:
 加padding后:签名验证失败(说明exchange hash计算方式不同)
 不加padding:签名成功但MAC失败(说明不是padding问题)

结论:
OpenSSH exchange hash calculation可能不包括padding bytes
需要进一步验证OpenSSH如何计算exchange hash

下一步建议:
1. 检查OpenSSH exchange hash calculation是否重新构建packet(包括padding)
2. 或验证OpenSSH kex->my是否也包括padding
3. 或使用OpenSSH server对比测试(手动启动)

4778081866 Critical fix: KEXINIT exchange hash encoding (prepend SSH_MSG_KEXINIT byte)
Some checks failed
Test / test (push) Has been cancelled
Test / build (push) Has been cancelled
OpenSSH kexgex.c source code analysis:
- KEXINIT payload stored without SSH_MSG_KEXINIT type byte
- Exchange hash prepends SSH_MSG_KEXINIT byte (20) with adjusted length

Before fix:
- client_kexinit_payload included SSH_MSG_KEXINIT byte
- Direct use without prepending

After fix:
- Remove SSH_MSG_KEXINIT byte from payload
- Prepend byte (20) in exchange hash with length+1
- Both kex_exchange.rs and kex_complete.rs updated

Testing result: MAC still fails, indicating additional encoding issues
Next: Detailed comparison of all exchange hash components
