PowerShell/Win32-OpenSSH#1211PowerShell/Win32-OpenSSH#1082
Added support for posix_spawnp that executes the command directly instead of appending path. (SH_ASKPASS and proxy command use this). Refactored posix spawn commandline building logic to automatically account for Windows CRT escaping rules on all arguments.
- Updated code to dynamic load Lsa functions until RS5 SDK includes them
- Add conpty support in openssh
- Fixed Wierd characters (?25l) are seen, when logged in from ssh client
- Backspace doesn't work in powershell window
- Changes to support ssh-shellhost as an alternative shell
- Added support to have ssh-shellhost work as a standby shell (ssh-shellhost -c "cmdline") simply executes cmdline via CreateProcess
- Added E2E test cases and fixed unittests broken from prior changes
- Added PTY launch interface that supports both conpty and ssh-shellhost pty.
- Implemented PTY control channel in ssh-shellhost that supports Window resize events.
- Fixed regression with starting a PTY session with an explicit command
- modified ssh-shellhost pty argument to ---pty to remove ambiguity in cases when both -p and -c are present in commandline. Ex. ssh-shellhost.exe -c "myprogram -p -c argument"
- Logic to support conpty (currently disabled until validation is complete)
- fdopen() and fchmod() support for file handles
- support for auto updating known_hosts via ssh and ssh-keygen
- Support for dynamic Windows-size changes with PTY
- Changes to support OneCore SDK
- Test cases
Added utility to build session process command line - this accounts for restrictions from various shells. With these changes, scp and sftp-server are expected to be machine wide PATH if a custom shell (other than cmd.exe) is defined. Added comprehensive test cases.
Fixed issue with USERNAME env variable containing domain prefix too.

* Alternate Thread Creation API To Avoid Memory Leaks
- Switched from CreateThread() to _beginthreadex() and ExitThread() to _endthreadex() in order to avoid potential leaks when linking with static CRT library.
- Addressed a variety of warnings that were being detected with static code analysis.
* Addressed Type Cast Warning
- Added explicit cast to the output of _beginthreadex() to avoid a compiler warning.
* Indentation Fix
- Added chroot implementation that simply stores the path in internal state and sets an environment variable
- Spawned processes pickup chroot from environment variable
- Core change in realpath and resolved_path_utf16 now take into account chroot path.
- Unit tests
- Other miscellaneous changes to account for chroot enabled logic in core code
PowerShell/Win32-OpenSSH#190PowerShell/Win32-OpenSSH#292
1. Add support to take key files with windows new line ending (PowerShell/Win32-OpenSSH#1130)
2. add test cases for CRLF
3. Update test helper script to catch the exitcode of unittest and report the failure
4. Enable uni test unittest-sshkey and unittest-sshkey
5. Disable resource check for signal tests due to some API issue to follow.
6. Remove workaround for windows new line ending in test scripts
7. Add test validation for ACL of registry entries when perform ssh-add
- Reworked resolved_path() into resolved_path_utf16() that combined utf16 conversion and path conditioning into a single function. This eliminated the previously non-threadsafe resolved_path() function.
- Adjusted functions to use resolved_path_utf16().
- Collapsed copy_file() function that was only used once.
- Corrected compilation errors when debug4() and debug5() are enabled.
- Added implementation of symlink() using native CreateSymbolicLink() function.
- Added unit tests for symlink behavior in readlink(), lstat, stat(), and symlink().
- Reworked readlink() to be more inline with POSIX readlink() behavior.
- Reworked symlink handling in stat/lstat due to revised readlink().
- Added additional error handling to readlink().
- Added symlink() Implementation - Memory Leak Fix
- Modified fileio_readlink() to properly free a temporary buffer it creates.
- Added wait_for_multiple_objects_enhanced() function that can logically handle wait-any on many children (system resources permitting).
- Added unit tests for wait_for_multiple_objects_enhanced().
- Incorporated use of wait_for_multiple_objects_enhanced() into main signal handler.
- Upped max child processes to 500.
OpenSSh privilege separation model - http://www.citi.umich.edu/u/provos/ssh/privsep.html
Posix_spawn is implemented in POSIX adapter as an alternative to fork() that is heavily used in Privilege separation.
Additional state info is added to sshd to accommodate distinguishing the various modes (privileged monitor, unprivileged child, authenticated child).
Required service state (like config and host keys) is transmitted over pipes from monitor to child processes.
Changes to installation scripts and tests to accomodate new architectural changes
docker ssh issue
PowerShell/Win32-OpenSSH#666
a) fdopen changes to accept the /dev/null device
b) fix the select (using same fdset as readfdset, exceptfdset) issue with the unix opensssh code.
changed keyscan pester test to refer to localhost (127.0.0.1) instead of GitHub.com
PowerShell/Win32-OpenSSH#731
Fix the ASSERT_HANDLE issue..
ASSERT_HANDLE should fail if handle is either NULL or INVALID_HANDLE.
Added new testcases for the null device.
Change COMPILER_VERSION tests which limited additional
warnings to gcc4 to instead skip them on gcc3 as clang can handle
-Wpointer-sign and -Wold-style-definition.
