Rex-1.16.1
⭐ Starred 717 / Rex::Commands::Partition
Security Advisories (1)
CVE-2026-94140 (2026-10-21)

Rex versions through 1.16.1 for Perl accept an unknown SSH host key for remote rsync transfers because sync hardcodes StrictHostKeyChecking=no. Every remote branch of sync builds its ssh command with that option, for password authentication, for private-key authentication and for the fallback. The ssh options a caller sets through set_openssh_opt reach the OpenSSH transport but not this command, so there is no configuration that restores host key checking for the transfer. An attacker who can redirect the connection before the real host key is known presents their own and the transfer proceeds: under password authentication sync sends the connection password to that server, an upload writes the selected local files to it, and a download writes what it returns to the local destination.

NAME

Rex::Commands::Partition - Partition module

DESCRIPTION

With this Module you can partition your harddrive.

Version <= 1.0: All these functions will not be reported.

All these functions are not idempotent.

SYNOPSIS

use Rex::Commands::Partition;

EXPORTED FUNCTIONS

clearpart($drive)

Clear partitions on drive `sda`:

clearpart "sda";

Create a new GPT disk label (partition table) on drive `sda`:

clearpart "sda",
 initialize => "gpt";

If GPT initialization is requested, the `bios_boot` option (default: TRUE) can also be set to TRUE or FALSE to control creation of a BIOS boot partition:

clearpart "sda",
 initialize => "gpt",
 bios_boot => FALSE;

partition($mountpoint, %option)

Create a partition with the specified parameters:

ondisk

The disk to be partitioned. Mandatory.

size

Desired size of the partition in MB. It is mandatory to pass either a size or a grow parameter (but not both).

grow

If TRUE, then the partition will take up all the available space on the disk. It is mandatory to pass either a grow or a size parameter (but not both).

type

Partition type to be passed to parted's mkpart command. Optional, defaults to primary.

boot

Sets boot flag on the partition if TRUE. Optional, no boot flag is set by default.

fstype

Create a filesystem after creating the partition. Optional, no filesystem is created by default.

label

Label to be used with the filesystem. Optional, defaults to no label.

mount

If TRUE, try to mount the partition after creating it. Optional, no mount is attempted by default.

mount_persistent

If TRUE, try to mount the partition after creating it, and also register it in /etc/fstab. Optional, no mount or /etc/fstab manipulation is attempted by default.

vg

Creates an LVM PV, then creates the specified LVM VG (or extends it, if the VG already exists). Needs ondisk.

Examples:

partition "/",
  fstype => "ext3",
  size   => 15000,
  ondisk => "sda",
  type   => "primary";

partition "none",
  type   => "extended",
  ondisk => "sda",
  grow   => 1,
  mount  => TRUE,

partition "swap",
  fstype => "swap",
  type   => "logical",
  ondisk => "sda",
  size   => 8000;

partition "/",
  fstype => "ext3",
  size   => 10000,
  ondisk => "sda",
  vg     => "vg0";
