Add acls/{ACL}/attrib/authentication attribute that controls authentication for particular ACL. By default, this attribute inherits a value of the authentication attribute of the target port group to keep backward compatibility. authentication attribute has 3 states: "0" - authentication is turned off for this ACL "1" - authentication is required for this ACL "-1" - authentication is inherited from TPG Reviewed-by: Roman Bolshakov <r.bolshakov@yadro.com> Reviewed-by: Konstantin Shelekhin <k.shelekhin@yadro.com> Signed-off-by: Dmitry Bogdanov <d.bogdanov@yadro.com> --- v2: show effective value (-1) for inherited mode --- drivers/target/iscsi/iscsi_target_configfs.c | 31 +++++++++++++++++++ drivers/target/iscsi/iscsi_target_nego.c | 8 ++++- .../target/iscsi/iscsi_target_nodeattrib.c | 1 + include/target/iscsi/iscsi_target_core.h | 2 ++ 4 files changed, 41 insertions(+), 1 deletion(-)
