squashfs files showing as unlabeled_t

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

 

I’m working on a project using a selinux reference policy on an embedded system.  The device uses a squashfs file system that is labeled during build time.  During the build, policy file labels are applied using Pseudo and setfiles with an alternate root path specified. 

 

Using a Fedora system it is possible to mount the squashfs file and confirm the file labels are correct.  When checked on target system the squashfs files are incorrect, but ram disk files are correct.  All squashfs files are system_u:object_r:unlabeled_t

 

The kernel .config values for squsahfs and selinux here here

 

CONFIG_SQUASHFS=y

CONFIG_SQUASHFS_XATTR=y

CONFIG_SQUASHFS_ZLIB=y

CONFIG_SQUASHFS_LZO=y

CONFIG_SQUASHFS_XZ=y

# CONFIG_SQUASHFS_4K_DEVBLK_SIZE is not set

CONFIG_SQUASHFS_EMBEDDED=y

CONFIG_SQUASHFS_FRAGMENT_CACHE_SIZE=10

 

CONFIG_SECURITY_SELINUX=y

CONFIG_SECURITY_SELINUX_BOOTPARAM=y

CONFIG_SECURITY_SELINUX_BOOTPARAM_VALUE=1

CONFIG_SECURITY_SELINUX_DISABLE=y

CONFIG_SECURITY_SELINUX_DEVELOP=y

CONFIG_SECURITY_SELINUX_AVC_STATS=y

CONFIG_SECURITY_SELINUX_CHECKREQPROT_VALUE=1

CONFIG_SECURITY_SELINUX_POLICYDB_VERSION_MAX=n

# CONFIG_SECURITY_SELINUX_POLICYDB_VERSION_MAX is not set

 

Has anyone else run into this problem?  Any suggestions on what may be wrong?

 

Regards,

josh
