Unraid OS 7.0.1 is Now Available

Unraid OS 7.0.1 Release Highlights

Tailscale Integration in Host Mode Security Update

A security issue was identified when the Tailscale integration is enabled on a container running in Host mode and then shared with other users. 

As of this release, the ability to launch such containers is disabled. To proceed, either:

• Disable the Tailscale integration for containers using Host mode
• Change the Network Type to Bridge or "Custom: eth0/bond0/br0"

Other Tailscale Docker Integration Changes

• Security Fix: Prevents containers with Network Type "Host" from using the Tailscale integration; existing containers in this configuration will not start, and users will be warned via Fix Common Problems if a container exists with this configuration.
• Container Logic Enhancement: Prevents containers with Network Type "Container" from using the Tailscale integration (the sidecar container should have Tailscale, not the main container).
• Community Apps Support: Accepts the default Tailscale state directory from Community Apps.
• Certificate Management: Installs ca_certificates if needed.
• Command Handling Improvement: Improves handling of post arguments when the Tailscale integration is enabled—everything before the first ";" is passed to the container, while everything after it executes on the host.
• Future Enhancements: Work is underway to allow managing the official Tailscale sidecar container using this integration.

Bug Fixes and Improvements

• Memory Management: Fixes a possible cause of an nchan memory leak.
• File Manager: Allows access to Unassigned Devices (UD) remote shares.
• Hardware Support: Increases the number of SD devices detected during early boot from 8 to 16.
• Btrfs Pool Expansion Fix: Resolves "Wrong Pool State" and invalid expansion errors when upgrading certain btrfs pools from OS version 6.12.
• Partition Management: Prevents the import of existing vfat partitions.
• Array Management: Fixes an issue preventing the array from starting when a pool is defined but not assigned.

Mover Improvements

• Fixes an issue where mover is not transferring shares with spaces in the name from the array to a pool.
• Resolves an issue where mover is not handling hard links properly.

Virtual Machines 

• Fix: Issue where VMs with single quotation marks in the name could not start or stop.
• Fix: Issue where creating a VM under certain conditions unintentionally created a new share with the VM name.
• Fix: Issue where the Discard field on vDisk appeared blank.

Docker Improvements

• Container Management: Hides the update status for containers managed by third-party tools.
• Driver Blacklisting: Blacklists the cdc_ether driver to prevent issues with IPMI NICs on certain motherboards. To re-enable this driver, run: touch /boot/config/modprobe.d/cdc_ether.conf
• DHCP Fix: Downgrades dhcpcd to an earlier version to resolve DHCP issues some users were experiencing.

UI & Diagnostics Improvements

• Share Listing Fix: Tooltip now correctly displays spaces instead of %20 encoding.
• Diagnostics Enhancement: Includes installed patches in system diagnostics.
