I am porting Legato framework 16.01.2 on to IMX6 Sabersd board. I have compiled framework using IMX6 toolchain and placed on the board.

Started framework by running “start” script from /mnt/legato, I could see “Could not set extended attribute. Operation not supported” while executing following commands.

`	xattr set security.SMACK64 "*" /dev/null
	xattr set security.SMACK64 "*" /dev/zero`

Can you guide me to fix the error while executing xattr on /dev/null and /dev/zero.

Alex Jiang is travelling today, so I’m quoting his response:

Since /dev/zero is a kernel file system this should always work unless it has been disabled. I don’t know if there is a kernel configuration to enable extended attributes but I would check there first.

After enabling kernel configuration as shown below, the issue was fixed.

`
security options -> Enable different security models : 
                         Simplified Mandatory Access Control Kernel support
                         Default securitymodule(Simplified Mandatory Access Control)`
