Vivek Goyal 5afc8df46c virtiofsd: xattr mapping add a new type "unsupported" ... Right now for xattr remapping, we support types of "prefix", "ok" or "bad". Type "bad" returns -EPERM on setxattr and hides xattr in listxattr. For getxattr, mapping code returns -EPERM but getxattr code converts it to -ENODATA. I need a new semantics where if an xattr is unsupported, then getxattr()/setxattr() return -ENOTSUP and listxattr() should hide the xattr. This is needed to simulate that security.selinux is not supported by virtiofs filesystem and in that case client falls back to some default label specified by policy. So add a new type "unsupported" which returns -ENOTSUP on getxattr() and setxattr() and hides xattrs in listxattr(). For example, one can use following mapping rule to not support security.selinux xattr and allow others. "-o xattrmap=/unsupported/all/security.selinux/security.selinux//ok/all///" Suggested-by: "Dr. David Alan Gilbert" <dgilbert@redhat.com> Signed-off-by: Vivek Goyal <vgoyal@redhat.com> Message-Id: <YUt9qbmgAfCFfg5t@redhat.com> Reviewed-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com>		2021-10-25 18:48:23 +01:00
