f2fs xattr and SELinux

[Konstantin Dorfman <kdorfman@codeaurora.org>]

Hi all,

I'm trying to use f2fs xattr with SELinux (on android) and getting 
following error:

root# restorecon -Rv /data
Relabeling /data from u:object_r:unlabeled:s0 to 
u:object_r:system_data_file:s0.
Could not label /data with u:object_r:system_data_file:s0: Operation not 
supported on transport endpoint

Also, output of `ls -Z` command (all files/dirs are unlabeled):

root# ls -Z /data
drwxrwx--x system   system            u:object_r:unlabeled:s0 app

drwxrwx--- media_rw media_rw          u:object_r:unlabeled:s0 media

mount output is:
/dev/block/bootdevice/by-name/userdata /data f2fs 
rw,nosuid,nodev,relatime,background_gc_on,discard,user_xattr,acl,active_logs=6 
0 0

Any comments/ideas about why xattr is not working for me on f2fs?

Thanks,
Kostya
