* net/smc: hold conns_lock before calling smc_lgr_register_conn()Huaping Zhou2019-06-261-0/+3
| | | | | | | | | | | | | | | After smc_lgr_create(), the newly created link group is added to smc_lgr_list, thus is accessible from other context. Although link group creation is serialized by smc_create_lgr_pending, the new link group may still be accessed concurrently. For example, if ib_device is no longer active, smc_ib_port_event_work() will call smc_port_terminate(), which in turn will call __smc_lgr_terminate() on every link group of this device. So conns_lock is required here. Signed-off-by: Huaping Zhou <zhp@smail.nju.edu.cn> Signed-off-by: Ursula Braun <ubraun@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | Rework smc_conn_create() to always return a valid DECLINE reason code.

* net/smc: cleanup of get vlan idKarsten Graul2019-04-121-4/+0
| | | | | | | | | | | | The vlan_id of the underlying CLC socket was retrieved two times during processing of the listen handshaking. Change this to get the vlan id one time in connect and in listen processing, and reuse the id. And add a new CLC DECLINE return code for the case when the retrieval of the vlan id failed.

| * net/smc: prevent races between smc_lgr_terminate() and smc_conn_free()Karsten Graul2019-02-011-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | To prevent races between smc_lgr_terminate() and smc_conn_free() add an extra check of the lgr field before accessing it, and cancel a delayed free_work when a new smc connection is created. This fixes the problem that free_work cleared the lgr variable but smc_lgr_terminate() or smc_conn_free() still access it in parallel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | SMC code uses the base gid for VLAN traffic. The gids exchanged in the CLC handshake and the gid index used for the QP have to switch from the base gid to the appropriate vlan gid. When searching for a matching IB device port for a certain vlan device, it does not make sense to return an IB device port, which is not enabled for the used vlan_id.

| * net/smc: add base infrastructure for SMC-D and ISMHans Wippel2018-06-301-66/+204

For data transport, SMC-R uses RDMA devices, SMC-D uses so-called Internal Shared Memory (ISM) devices. An ISM device only allows shared memory communication between SMC instances on the same machine. For example, this allows virtual machines on the same host to communicate via SMC without RDMA devices. This patch adds the base infrastructure for SMC-D and ISM devices to the existing SMC code. It contains the following: * ISM driver interface: This interface allows an ISM driver to register ISM devices in SMC. In the process, the driver provides a set of device ops for each device. SMC uses these ops to execute SMC specific operations on or transfer data over the device. * Core SMC-D link group, connection, and buffer support: Link groups, SMC connections and SMC buffers (in smc_core) are extended to support SMC-D. * SMC type checks: Some type checks are added to prevent using SMC-R specific code for SMC-D and vice versa. To actually use SMC-D, additional changes to pnetid, CLC, CDC, etc. are required. These are added in follow-up patches.

* net/smc: longer delay when freeing client link groupsUrsula Braun2018-05-231-1/+1
| | | | | | | | | | | | | | | | | | Client link group creation always follows the server linkgroup creation. If peer creates a new server link group, client has to create a new client link group. If peer reuses a server link group for a new connection, client has to reuse its client link group as well. To avoid out-of-sync conditions for link groups a longer delay for for client link group removal is defined to make sure this link group still exists, once the peer decides to reuse a server link group. Currently the client link group delay time is just 10 jiffies larger than the server link group delay time. This patch increases the delay difference to 10 seconds to have a better protection against out-of-sync link groups. Signed-off-by: Ursula Braun <ubraun@linux.ibm.com> Signed-off-by: David S.
