ReactOS 0.4.14 released

Post by EmuandCo »

The ReactOS Team is pleased to announce the release of version 0.4.14. As with every other release, we’re regularly noting improvements and updates to keep you in touch with what is being done in ReactOS. In this release, improvements range from FreeLoader fixes, Shell features, kernel fixes, NetKVM VirtIO bringup, further work on the Xbox port and support for NEC PC-9800.

Note that it took us over a year to get this release in shape and fix regressions. As such, ReactOS 0.4.14 does not contain the very latest developments we advertised in 2021 on our blog and on social media. They can be found instead in our nightly builds. Consider this a maintenance release, and stay tuned for what’s coming next!

“Send To” feature and Shell improvements
One of the main highlights of this release is the amount of improvements done to the Shell component, which makes up a vital part of the ReactOS user experience. Katayama Hirofumi MZ is the pioneer of the “Send To” implementation, a feature of the Shell that can be used to send files or directories to a certain predefined location.

In addition, “Open File Location” and “Open Command prompt here” were also implemented thanks to him. Apart from the aforementioned features, let’s not forget the bug fixes that affected the operability of the Shell. Katayama Hirofumi MZ fixed the scroll selection and Mark Jansen improved some COM (Component Object Model) interfaces, so that certain drag-and-drop regressions could be fixed. The implementations of “Send To” and “Open File Location” are shown in the screenshots below:

NEC PC-9800 boot support
NEC PC-9800 (or PC-98 in short) is a series of 16-bit and 32-bit Japanese computers developed and manufactured by NEC. As that type of hardware is based on x86 processors, it is a relatively easy porting target. Nevertheless, every port to another architecture opens up possibilities for finding and fixing bugs in the core modules of ReactOS.

Dmitry Borisov, a new ReactOS contributor, helped to get the PC-98 port in shape. While there is work left to be done in the development of PC-98 boot support, Dmitry Borisov made great strides to get ReactOS booting on that platform. The following screenshot below demonstrates ReactOS booting on the Neko Project 21/W emulator.

ICMP improvements
Internet Control Message Protocol (or ICMP by short) is a protocol used by network devices to send and receive information such as errors or log status. The implementation, primarily residing in our IP Helper API module (iphlpapi.dll), was rather scarce and incomplete with pieces of code unimplemented or unfinished.

Thanks to Victor Perevertkin, and with the help of Tim Crawford, the ICMP protocol implementation has seen lots of improvements. These range from the implementation of the IOCTL_ICMP_ECHO_REQUEST I/O control code to a full rewrite of the Icmp** routines. As a result, the network device drivers can now pass ICMP request and response packets to the applications in a correct manner. This is proven in the screenshot below, which shows the tracert command-line utility now outputting complete information.

Kernel improvements
The ReactOS kernel is responsible for the correct functioning of the operating system and interfacing with the bare metal. The stability of the system drastically relies on the robustness of the kernel. Every bug counts here.

With every release, the developers squash bugs in the kernel to offer a better overall stability and experience. ReactOS 0.4.14 comes with several improvements to the Memory Manager thanks to Thomas Faber. Speaking of the aforementioned module, Vadim Galyant did some initial work on PAE (Physical Address Extension) and contributed towards the Memory Manager sections rewrite.

Timo Kreuzer added CRT (C Run-Time) exception handling by importing related code from WINE. This allows 64-bit development to proceed as various bugs and random hangs on 64-bit systems have been resolved. Victor Perevertkin fixed a bug in the storage class PnP driver (classpnp.sys) and both Timo Kreuzer and Thomas Faber fixed some buffer overflow vulnerabilities. Finally, Eric Kohl improved the device action worker code in the I/O subsystem.

Let’s not forget about the PnP (Plug n’ Play) manager of the kernel, which is another important part not only in regard to stability, but also regarding the usability of the system with a plethora of hardware. Vadim Galyant added an initial implementation of the Resource Arbiter library, which is going to be used by bus drivers like PCI to manage resource conflicts. In addition to that, Vadim implemented debug code both in PnP and I/O managers, whereas Eric Kohl improved the PnP manager to map device capabilities to capability flags. Thomas Faber fixed a critical bug that could cause memory corruption in the kernel space. Furthermore, he fixed a faulty IRP (I/O Request Packet) handling that caused a Blue Screen on an Original Xbox console with USB enabled.

The Kernel Debugger (KD) and related modules have also received updates from developers and contributors alike. Dmitry Borisov added a ComPort library for NEC PC-98, which is fundamental in the further development and support of NEC series. Hermès Bélusca-Maïto has finished the support for debug filters, improved the cregs and tss commands included in the interactive kernel debugger (KDBG, present only in GCC debug builds), rewrote the TSS handling code and squashed various bugs with it. Furthermore, Jérôme Gardou alongside with Hervé Poussineau brought some fixes and improvements to the KDBG module.

NetKVM VirtIO bringup
NetKVM VirtIO is an NDIS 5 compatible driver developed by Red Hat Inc., which allows fast VirtIO networking in virtual machine software such as QEMU and other KVM hardware accelerated virtual machines. Nguyen Trung Khanh, a ReactOS contributor, took over Benjamin Aerni’s work of importing the driver into the source tree of ReactOS. This provides ReactOS with support for another network interface out of the box.

Miscellaneous changes & improvements
Other areas of the ReactOS operating system have received lots of improvements by various contributors, ranging from device drivers to software applications. Notably FreeLoader, the ReactOS bootloader, received incremental fixes and improvements.

Hermès Bélusca-Maïto added support for booting Linux 64-bit systems in 64-bit FreeLoader and fixed an issue where FreeLoader couldn’t read from an EXT2 volume, hence preventing booting. Dmitry Borisov fixed a serious triple fault bug when ReactOS was booted up in Screen debugging mode. In addition to that, Dmitry Borisov also provided other fixes as well as added ARC-emulation support necessary for NEC PC-98 series. Stanislav Motylkov still continues his work on Xbox boot support, contributing various fixes and patches. This is mainly the platform bring-up, refactoring, and abstraction of existing low-level code. Hermès Bélusca-Maïto also fixed several old bugs, notably a corruption in the console emulation (CONSRV) layer’s memory when converting input events back to ANSI, and a bug in HAL that sporadically caused an assertion failure.

George Bișoc updated the On-Screen Keyboard and Accessibility Utility Manager and at the same time provided minor fixes and improvements to different parts of ReactOS.

Hervé Poussineau worked hard on the ISA PnP driver which detects ISA devices, however that driver is not yet activated. Mark Jansen fixed a bug in the comctl32 (Common Controls) module, which lead to an incorrectly rendered Visual Basic 6 installer. Eric Kohl worked on the “Safely Remove Hardware” dialog, which now enumerates the peripherals for safely removal.

What is particularly different between 0.4.13 and this release is the sleek performance increase due to obsolete fonts being removed by Katayama Hirofumi MZ. This both reduced the binary size of this release and the RAM consumption. Here is a comparison between 0.4.13 (with the obsolete fonts loaded in memory) and 0.4.14.

Third Party Syncs
ReactOS is a FOSS (Free Open Source Software) operating system that is both free as in “free beer” and open source, meaning that people can study the OS and contribute code. As such, ReactOS shares modules and code from other third-party open source projects, which are regularly updated by the ReactOS developers. The following syncs are part of this release:

Wine Staging 4.18 user mode DLLs by Amine Khaldi
mpg123 1.25.13 by Thomas Faber
libjpeg 9d by Thomas Faber
mbedtls 2.7.14 by Thomas Faber
libtiff 4.1.0 by Thomas Faber
ACPICA 20200326 by Thomas Faber
BtrFS 1.7.2 by Pierre Schweitzer and Victor Perevertkin
glu32 9.0.1 by Masanori Ogino
Updated root certificates by Thomas Faber

It still fails to boot from a USB formatted with rufus 3.17. Are others experiencing this, too?

Did you read the installation instructions? Have you read the ReactOS WIKI FAQ? Or did you just install without reading or checking anything? Suspect the latter.

Almost everyone will experience problems booting from USB, for some it may work but they will be the lucky ones!

Read the FAQ and check the state of USB implementation, check the state of ReactOS itself while you are there.

And locked. This is no support thread and from now on I will force anyone to create a topic as it should be done...
