Resolving issues with GMail and OAuth 2.0 requirements

At the end of May, 2022, GMail discontinued use of standard authentication methods for POP3, IMAP, and SMTP connections. The available OAuth2 authentication mechanism in the latest SeaMonkey and Thunderbird for the OS/2 platform is unable to properly complete the authentication procedure with GMail, and will leave the application in a hung state.

There are several methods to work around this, but perhaps the easiest is simply to generate what Google calls an app password, which is, quite simply, a 16-digit passcode which gives a non-Google application or device permission to access your Google Account.

To generate the app password, follow the directions available here. Remember, that in order to do this, you must have 2-Step-Verification enabled for your account.

Once you have generated the app password, copy it to your clipboard. Open SeaMonkey Mail or Thunderbird, and access the server settings for your GMail account. Ensure that the authentication method is set for Normal password (Google will not accept encrypted passwords for this). Make the same change for the GMail SMTP server. Note that in both cases, SSL/TLS should be selected for the connection security, and specifically not STARTTLS. Close the settings dialog and attempt to access the account. You should be prompted for a new password. Paste the app password into the prompt.

To configure a second system to access the same account, simply paste (or type) the same app password. This technique should work for other mail clients, as well.

For questions, there is an informative discussion in the OS/2 World forum on this very topic.

 

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.)

UEFI support in ArcaOS 5.1 – update for February, 2022

Development and testing of Arca Noae’s support for UEFI continues. Here’s a brief recap of how this will work in ArcaOS 5.1:

When the installation media boots, if the system is determined to be in “UEFI mode” as opposed to “Legacy mode” (“Legacy” here refers to the configuration which presents a traditional PC BIOS), ArcaOS will begin the preboot process using its compatibility system. Essentially, this is a 64-bit environment which will provide a rather complete BIOS emulation for the ArcaOS kernel, including VGA services for video display.

If the user selects to use his own settings for installation (the preboot menu), the screens will look and act just like a traditional installer boot, but will, in fact, be provided by this new compatibility system.

Once control is handed off to the ArcaOS kernel, the OS itself is exactly the same as a traditional ArcaOS boot. That is to say, the kernel is identical. The goal of the Arca Noae Compatibility System (ANCS) is to provide a standard environment for ArcaOS, without the need to actually maintain different versions of ArcaOS files for each environment. Another benefit of ANCS is that because the video BIOS emulation is generally more complete than that provided by the CSM in many systems built in the past decade, DOS and Win-OS/2 sessions tend to run much better.

ArcaOS 5.1 should support booting in UEFI mode on a range of systems which provide a recent UEFI implementation, from either GPT or MBR partitioned disks. In the next post in this series, we’ll discuss GPT and MBR and how the boot process differs between the two partition layouts.

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.

ArcaOS Desktop updated to 1.0.14

Dynamic Icons[Edit: Download links have been properly adjusted as of this writing, and should all be working. Apologies for any inconvenience.]

Arca Noae is pleased to announce the immediate availability of ArcaOS Desktop (ANXWP) 1.0.14 in English, German, Dutch, Spanish, Italian, Japanese, and Russian. This is a maintenance release containing bug-fixes and updates that have accumulated over the last year. The primary improvements include:

XShutdown

  • Power-off options have been simplified. The ACPI/APM shutdown option has been removed since the system always uses ACPI if it is available.
  • The shutdown sound which failed to play in Lite versions has now been restored.
  • The XShutdown dialog has been updated to suppress the list of BIOS-bootable partitions when booted in UEFI mode. It should also do a better job of handling situations where the data it collects from AirBoot is corrupt.

Folder Refresh

This feature has been completely rewritten to ensure that every filesystem update is reflected in the display within 1.5 seconds. The rewrite also fixes a bug where the code might try to delete a file that had been deleted then recreated.

Russian NLS (NEW)

Initial Russian language support has been provided by Yurii Zamotailo.

In addition, included is a minor update to Arca Noae Removable Media Monitor which suppresses attachment notifications (and subsequent failure messages) when USB floppy drives and some USB optical drives are plugged in.

Arca Noae announces GUID for OS/2 Type 1 GPT partitions

In our last post concerning GPT in ArcaOS, we discussed the first phase of support and how our specification allows for multiple partitions up to 2TB in size. As every GUID (Globally Unique Identifier) partition type requires a GUID, we have set:

90B6FF38-B98F-4358-A21F-48F35B4A8AD3

as the GUID for OS/2 Type 1 partitions.

Any GPT partition using this GUID should ultimately be recognizable by any GPT-aware operating system as belonging to ArcaOS.

Although this is now just a simple proclamation, it is, in point of fact, a major advancement for the platform, and sets the stage for our initial GPT support, currently planned for release with ArcaOS 5.1 in 2021.

Arca Noae makes no guaranty as to availability of GPT support for ArcaOS 5.1. When available, GPT support will be an ArcaOS feature only, with no plans to make the technology available for other OS/2 distributions.

Don’t have ArcaOS yet? Now is a great time to pick up a license or two and replace those aging Warp 4 or eComStation installations and get to know what’s new and improved. If you’ve never run OS/2 before, you’ll be amazed. If you last used OS/2 in the 1990’s, you’ll be even more amazed. ArcaOS runs the vast majority of existing OS/2 Warp 4 software, because it really is OS/2 – just better. ArcaOS supports more modern hardware than any other OS/2 distribution available today, making hardware upgrades much easier than ever before. An ArcaOS 5.0 license now means steep discounts on future upgrades, including 5.1.

Arca Noae’s plan for supporting GPT disk layouts in ArcaOS

Through the release of ArcaOS 5.0.6, all OS/2 distributions have only supported MBR (Master Boot Record) partitioning schemes, that is, up to four partitions on a disk, with the possibility of creating multiple logical volumes in one extended partition. This partitioning scheme is also limited to a maximum of 2TB per disk.

The GPT (GUID Partition Table) breaks out of these restrictions by supporting an almost unlimited number of partitions (without the need for logical volumes) and disks exceeding 2TB.

Supporting GPT is another major step for multiboot configurations where the disk has already been partitioned using this style, which will allow ArcaOS to install alongside other GPT-aware operating systems (Windows 10, modern Linux distros, etc.), without the need to install a second MBR-partitioned disk or to wipe, re-partition, and reformat all volumes on the existing disk.

Arca Noae’s approach to supporting GPT will be multi-phased, with the first phase of development currently underway and anticipated for release with ArcaOS 5.1. The design specification of our initial GPT support is to allow for partitions up to the current 2TB maximum size, with multiple partitions of this size possible on disks larger than 2TB. Our specification further provides that ArcaOS be able to create, delete, and modify GPT partitions which are identified by their GUIDs as being “OS/2-type” partitions, and lastly, that GPT support be available for both traditional BIOS (for data volumes) and UEFI-based systems (for boot and data volumes).

Arca Noae makes no guaranty as to availability of GPT support for ArcaOS 5.1. When available, GPT support will be an ArcaOS feature only, with no plans to make the technology available for other OS/2 distributions.
