GPT usability in ArcaOS 5.1.0

In our last post we discussed that the upcoming ArcaOS 5.1.0 release will be able to make use of laptops and desktops that only support booting in so-called UEFI mode.

When booting ArcaOS in UEFI mode, the disk partitioning scheme may use the traditional Master Boot Record (MBR) or the newer GUID Partition Table (GPT). Although MBR has been extended to support disks up to 2TB, with ever-growing disk sizes, this may be too limiting for devices which could otherwise support handling more data than this. Also, if installing to a disk which is already configured using GPT, releases of ArcaOS prior to 5.1.0 require a full wipe and repartition of the disk. This inconvenience should no longer be an issue in ArcaOS 5.1.

Thus, ArcaOS 5.1.0 will be able to utilize GPT disk layouts with the following benefits:

  • Support for hard disks and solid state drives larger than 2TB attached to AHCI or NVMe storage controllers.
  • On systems equipped with a single drive and Windows pre-installed using a GPT layout, there should be no need to wipe and repartition, as long as there is room for ArcaOS to create at least one partition for itself.
  • GPT eliminates many of the LVM issues you may have encountered in the past when preparing a disk to install ArcaOS next to other operating systems, such as Linux and Windows because ArcaOS will use the same LBA partition alignment method (for GPT disk layouts) as these other operating systems.

GPT usage has been integrated into the ArcaOS installation partitioning tool (Logical Volume Manager), giving you a seamless experience while installing and maintaining ArcaOS.

Of course, ArcaOS 5.1.0. will continue to support your existing hard disks that have been partitioned using an MBR disk layout, too. In fact, a mix of GPT and MBR disks is also possible, and you will also be able to install ArcaOS in a UEFI environment on an MBR disk (GPT is completely optional, and never a requirement).

It is also important to remember that while ArcaOS 5.1.0 will support hard disks and SSDs larger than 2TB, OS/2 filesystems are currently limited to 2TB per partition. Thus, in order to fully utilize, say, a 12TB device for ArcaOS, you would need to partition this into multiple volumes, each no more than 2TB in size. (Also, for volumes in excess of 64GB, you must select JFS as the filesystem.)

USB driver package version 12.11 now available

Arca Noae is pleased to announce the immediate availability of release 12.11 of our USB stack.

This is a maintenance release that contains some minor fixes, including:

  1. In USBOHCD a typo was fixed in the strings passed to the Resource Manager.
  2. In USBMSD additional stall recovery was added to handle certain errors from floppy devices.
  3. In USBHID a workaround was added to handle some rare keyboards with unusual descriptors.
  4. In USBXHCD a workaround was added for the VirtualBox port change defect.

Most people will see no change in operation after installing this update. See the package readme.txt for details. This update is recommended for all users.

As usual, this release is update only. It will only update an existing installation. More information about the USB drivers can be found in the wiki.

Apache Log4j vulnerability (CVE-2021-44228)

On Thursday, December 9, 2021, the Apache Log4j project disclosed a critical security vulnerability which may result in remote code execution on systems running Log4j. The exploit has been aptly named Log4Shell (CVE-2021-44228).

Log4j is a logging component which runs under Java on many different platforms, and is useful not only for Java applications, but for other programs, as well. It is commonly bundled with unrelated software, simply as a means of providing a standard logging engine.

Arca Noae has completed a scan of our internal systems and has determined that we are not affected by this vulnerability. Further, ArcaOS has never included any Log4j components, and is also unaffected. However, because the exploitable feature in Log4j has existed for some time, it is possible that Java and other applications may have been installed under ArcaOS which utilize Log4j, and these systems may be at risk.

The feature used for the Log4Shell exploit is in the JNDI (Java Naming and Directory Interface) lookup class which was added to Log4j several years ago during the 2.0 beta cycle. Log4j versions through 2.3 required only Java versions up to 1.6, and so may be utilized by some OS/2-compatible applications.

Risk assessment

To determine whether any of your OS/2 systems may be at risk, start by searching all accessible volumes for log4j-*.jar. If any are found, determine the version of Log4j by examining the content of META-INF/MANIFEST.MF in the core jar file:

[c:\] unzip -c log4j-core.jar META-INF/MANIFEST.MF | less

Note the Implementation-Version line content.

Edge servers as well as firewalled systems running various applications may be at risk, as queries may be submitted to the Log4j engine from other applications and potentially from outside the network.

Mitigation

Although the exploit has been addressed in Log4j 2.16.0, because versions above 2.3 are not currently compatible with OS/2’s available Java Runtime Engine, it is necessary to mitigate the condition by removing the JndiLookup class from the classpath, e.g.:

[c:\] zip -q -d log4j-core-*.jar org/apache/logging/log4j/core/lookup/JndiLookup.class

Additional information

Older (pre-2.0-beta9) versions of Log4j lack this lookup class, and do not appear to be at risk for Log4Shell (though some earlier security advisories may have been issued). Further research may be needed based upon the version(s) of Log4j which may be in use on these earlier systems. Also, this is not the only security advisory for Log4j 2.0-beta9 – 2.3. This notification is only related to CVE-2021-44228.
