net/smc: Pass on DMBE bit mask in IRQ handler

2022-07-27T12:24:42+00:00

Make the DMBE bits, which are passed on individually in ism_move() as parameter idx, available to the receiver. Signed-off-by: Stefan Raspl Signed-off-by: Wenjia Zhang < wenjia@linux.ibm.com> Reviewed-by: Tony Lu Signed-off-by: David S. Miller

s390/ism: Cleanups

2022-07-27T12:24:42+00:00

Reworked signature of the function to retrieve the system EID: No plausible reason to use a double pointer. And neither to pass in the device as an argument, as this identifier is by definition per system, not per device. Plus some minor consistency edits.

net: add missing includes and forward declarations under net/

2022-07-22T11:53:22+00:00

This patch adds missing includes to headers under include/net. All these problems are currently masked by the existing users including the missing dependency before the broken header. Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

net/smc: introduce CHID callback for ISM devices

2020-09-28T22:19:03+00:00

With SMCD version 2 the CHIDs of ISM devices are needed for the CLC handshake. This patch provides the new callback to retrieve the CHID of an ISM device. Signed-off-by: Ursula Braun Signed-off-by: Karsten Graul Signed-off-by: David S. Miller

net/smc: introduce System Enterprise ID (SEID)

2020-09-28T22:19:02+00:00

SMCD version 2 defines a System Enterprise ID (short SEID). This patch contains the SEID creation and adds the callback to retrieve the created SEID. Signed-off-by: Ursula Braun Signed-off-by: Karsten Graul Signed-off-by: David S. Miller

net/smc: introduce bookkeeping of SMCD link groups

2019-11-15T20:28:28+00:00

If the ism module is unloaded return control from exit routine only, if all link groups are freed. If an IB device is thrown away return control from device removal only, if all link groups belonging to this device are freed. A counters for the total number of SMCD link groups per ISM device is introduced. ism module unloading continues only if the total number of SMCD link groups for all ISM devices is zero. ISM device removal continues only it the total number of SMCD link groups per ISM device has decreased to zero. Signed-off-by: Ursula Braun Signed-off-by: Karsten Graul Signed-off-by: David S.

net/smc: immediate termination for SMCD link groups

2019-11-15T20:28:28+00:00

SMCD link group termination is called when peer signals its shutdown of its corresponding link group. For regular shutdowns no connections exist anymore. For abnormal shutdowns connections must be killed and their DMBs must be unregistered immediately. That means the SMCR method to delay the link group freeing several seconds does not fit. This patch adds immediate termination of a link group and its SMCD connections and makes sure all SMCD link group related cleanup steps are finished.

net/smc: no new connections on disappearing devices

2019-10-10T02:45:44+00:00

Add a "going_away" indication to ISM devices and IB ports and avoid creation of new connections on such disappearing devices. And do not handle ISM events if ISM device is disappearing. Signed-off-by: Ursula Braun Signed-off-by: Karsten Graul Signed-off-by: Jakub Kicinski

net/smc: separate locks for SMCD and SMCR link group lists

This patch introduces separate locks for the split SMCD and SMCR link group lists. Signed-off-by: Ursula Braun Signed-off-by: Karsten Graul Signed-off-by: Jakub Kicinski

net/smc: separate SMCD and SMCR link group lists

2019-10-10T02:45:44+00:00

Currently SMCD and SMCR link groups are maintained in one list. To facilitate abnormal termination handling they are split into a separate list for SMCR link groups and separate lists for SMCD link groups per SMCD device.
