I think this is not needed, since the mode > change is just a side effect of the attribute change. Actually I think we want the security_inode_setattr. This is an implicit chmode when switching the ATTR_RO flag on and off and we should have the full security check for it. Then again I'm not sure the security modules care about this level of detail because there's probably even worse ioctl hidden somewhere. Ccing the Selinux guys and Casey in case they care. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
