IPoIB: Fix world-writable child interface control sysfs attributes

2010-07-06T21:23:22+00:00

Sumeet Lahorani reported that the IPoIB child entries are world-writable; however we don't want ordinary users to be able to create and destroy child interfaces, so fix them to be writable only by root. Signed-off-by: Or Gerlitz Cc: Signed-off-by: Roland Dreier

IB/iser: Fix error flow in iser_create_ib_conn_res()

2010-05-12T16:30:45+00:00

We shouldn't free things here because we free them later. The call tree looks like this: iser_connect() ==> initiating the connection establishment and later iser_cma_handler() => iser_route_handler() => iser_create_ib_conn_res() if we fail here, eventually iser_conn_release() is called, resulting in a double free.

IB/iser: Enhance disconnection logic for multi-pathing

2010-05-12T16:30:44+00:00

The iser connection teardown flow isn't over until the underlying Connection Manager (e.g the IB CM) delivers a disconnected or timeout event through the RDMA-CM. When the remote (target) side isn't reachable, e.g when some HW e.g port/hca/switch isn't functioning or taken down administratively, the CM timeout flow is used and the event may be generated only after relatively long time -- on the order of tens of seconds. The current iser code exposes this possibly long delay to higher layers, specifically to the iscsid daemon and iscsi kernel stack. As a result, the iscsi stack doesn't respond well: this low-level CM delay is added to the fail-over time under HA schemes such as the one provided by DM multipath through the multipathd(8) service. This patch enhances the reference counting scheme on iser's IB connections so that the disconnect flow initiated by iscsid from user space (ep_disconnect) doesn't wait for the CM to deliver the disconnect/timeout event. (The connection teardown isn't done from iser's view point until the event is delivered) The iser ib (rdma) connection object is destroyed when its reference count reaches zero. When this happens on the RDMA-CM callback context, extra care is taken so that the RDMA-CM does the actual destroying of the associated ID, since doing it in the callback is prohibited. The reference count of iser ib connection normally reaches three, where the relations are 1. conn 2. conn 3. cma id With this patch, multipath fail-over time is about 30 seconds, while without this patch, multipath fail-over time is about 130 seconds.

IB/iser: Remove buggy back-pointer setting

2010-05-12T16:30:44+00:00

The iscsi connection object life cycle includes binding and unbinding (conn_stop) to/from the iscsi transport connection object. Since iscsi connection objects are recycled, at the time the transport connection (e.g iser's IB connection) is released, it is not valid to touch the iscsi connection tied to the transport back-pointer since it may already point to a different transport connection.

IB/iser: Add asynchronous event handler

2010-05-12T16:30:43+00:00

Add handler to handle events such as port up and down. This is useful when testing high-availability schemes such as multi-pathing. Signed-off-by: Or Gerlitz Signed-off-by: Roland Dreier
