Extended attribute

[mariem]

Hello

I am actually working on Taintdroid 4.3 under emulateur. I would like to associate taint to file in "/dev", so I used the following instruction:
 

ret1 = fsetxattr(fd, "user.taint" , &tag, sizeof(tag), XATTR_CREATE);

I got an error message EPERM (not permitted) so I tried to change the instruction as follows:

ret1 = fsetxattr(fd, "system.taint" , &tag, sizeof(tag), XATTR_CREATE);

and I got an error message ENOTSUP (not supported)

How can I solve this problem?

Thanks for your help
