| | | * IB/iser: Replace connection waitqueue with completion objectAriel Nahum2014-08-01

Separate connection establishment wait object from the teardown object to avoid a situation where racing connection establishment and teardown may concurrently wakeup each other. ep_poll will wait for up_completion invoked by iser_connected_handler() and iser release worker will wait for flush_completion before releasing the connection. Bound the completion wait with a 30 seconds timeout for cases where iscsid (the user space iscsi daemon) is too slow or gone.

| | | * IB/iser: Protect iser state machine with a mutexAriel Nahum2014-08-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The iser connection state lookups and transitions are not fully protected. Some transitions are protected with a spinlock, and in some cases the state is accessed unprotected due to specific assumptions of the flow. Introduce a new mutex to protect the connection state access. We use a mutex since we need to also include a scheduling operations executed under the state lock. Each state transition/condition and its corresponding action will be protected with the state mutex. The rdma_cm events handler acquires the mutex when handling connection events. Since iser connection state can transition to DOWN concurrently during connection establishment, we bailout from addr/route resolution events when the state is not PENDING. This addresses a scenario where ep_poll retries expire during CMA connection establishment. In this case ep_disconnect is invoked while CMA events keep coming (address/route resolution, connected, etc...).

As a result we are keeping the corresponding iscsi_endpoint structure hanging for no good reason. In order to avoid that, we seperate iser_conn from iscsi_endpoint storage space to have their destruction being independent. iscsi_endpoint will be destroyed at ep_disconnect stage, while the iser connection will wait for asynchronous completions to be released in an orderly fashion.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the parent interface keeps sending broadcast group join requests even if p_key index 0 is invalid, which is possible/common in virtualized environments where a VF has been probed to VM but the actual P_key configuration has not yet been assigned by the management software. This creates unnecessary noise on the fabric and in the kernel logs: ib0: multicast join failed for ff12:401b:8000:0000:0000:0000:ffff:ffff, status -22 The original code run the multicast task regardless of the actual P_key value, which can be avoided. The fix is to re-init resources and bring interface up only if P_key index 0 is valid either when starting up or on PKEY_CHANGE event.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are 4 RDMA_CM events that all basically mean that the user should teardown the IB connection: - DISCONNECTED - ADDR_CHANGE - DEVICE_REMOVAL - TIMEWAIT_EXIT Only in DISCONNECTED/ADDR_CHANGE it makes sense to call rdma_disconnect (send DREQ/DREP to our initiator). So we keep the same teardown handler for all of them but only indicate calling rdma_disconnect for the relevant events. This patch also removes redundant debug prints for each single event. v2 changes: - Call isert_disconnected_handler() for DEVICE_REMOVAL (Or + Sag) Signed-off-by: Sagi Grimberg <sagig@mellanox.com> Cc: stable@vger.kernel.org # 3.10+ Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In ungraceful teardowns isert close flows seem racy such that isert_wait_conn hangs as RDMA_CM_EVENT_DISCONNECTED never gets invoked (no one called rdma_disconnect). Both graceful and ungraceful teardowns will have rx flush errors (isert posts a batch once connection is established). Once all flush errors are consumed we invoke isert_wait_conn and it will be responsible for calling rdma_disconnect. This way it can be sure that rdma_disconnect was called and it won't wait forever. This patch also removes the logout_posted indicator. either the logout completion was consumed and no problem decrementing the post_send_buf_count, or it was consumed as a flush error. no point of keeping it for isert_wait_conn as there is no danger that isert_conn will be accidentally removed while it is running.

Hence add fast registration support. In function srp_rport_reconnect(), move the the srp_finish_req() loop from after to before the srp_create_target_ib() call. This is needed to avoid that srp_finish_req() tries to queue any invalidation requests for rkeys associated with the old queue pair on the newly allocated queue pair. Invoking srp_finish_req() before the queue pair has been reallocated is safe since srp_claim_req() handles completions correctly that arrive after srp_finish_req() has been invoked.

This improves scalability of the SRP initiator. Only request the SCSI mid-layer to retry a SCSI command after a temporary mapping failure (-ENOMEM) but not after a permanent mapping failure. This avoids that SCSI commands are retried indefinitely if a permanent memory mapping failure occurs. Tell the SCSI mid-layer to reduce queue depth temporarily in the unlikely case where an application is queuing many requests with more than max_pages_per_fmr sg-list elements. For FMR pool allocation, base the max_pages_per_fmr parameter on the HCA memory registration limit. Only try to allocate an FMR pool if FMR is supported.

The problem is not directly memory reclamation. There is an indirect dependency between network filesystems writing back pages and ipoib_cm_tx_init() due to how a kworker is used. Page reclaim cannot make forward progress until ipoib_cm_tx_init() succeeds and it is stuck in page reclaim itself waiting for network transmission. Ordinarily this situation may be avoided by having the caller use GFP_NOFS but ipoib_cm_tx_init() does not have that information. To address this, take a general approach and add a new QP creation flag that tells the low-level hardware driver to use GFP_NOIO for the memory allocations related to the new QP. Use the new flag in the ipoib connected mode path, and if the driver doesn't support it, re-issue the QP creation without the flag.

Following commit 39ff05dbbbdb ("IB/iser: Enhance disconnection logic for multi-pathing"), iser connection maintain 3 references: - iscsi_endpoint (at creation stage) - cma_id (at connection request stage) - iscsi_conn (at bind stage) We can avoid taking explicit refcounts by correctly serializing iser teardown flows (graceful and non-graceful). Our approach is to trigger a scheduled work to handle ordered teardown by gracefully waiting for 2 cleanup stages to complete: 1. Cleanup of live pending tasks indicated by iscsi_conn_stop completion 2. Flush errors processing Each completed stage will notify a waiting worker thread when it is done to allow teardwon continuation. Since iSCSI connection establishment may trigger endpoint disconnect without a successful endpoint connect, we rely on the iscsi <-> iser binding (.conn_bind) to learn about the teardown policy we should take wrt cleanup stages. Since all cleanup worker threads are scheduled (release_wq) in .ep_disconnect it is safe to assume that when module_exit is called, all cleanup workers are already scheduled. Thus proper module unload shall flush all scheduled works before allowing safe exit, to guarantee no resources got left behind.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses a bug where an early exception for SCSI WRITE with ImmediateData=Yes was missing the target_put_sess_cmd() call to drop the extra se_cmd->cmd_kref reference obtained during the normal iscsit_setup_scsi_cmd() codepath execution. This bug was manifesting itself during session shutdown within isert_cq_rx_comp_err() where target_wait_for_sess_cmds() would end up waiting indefinately for the last se_cmd->cmd_kref put to occur for the failed SCSI WRITE + ImmediateData descriptors. This fix follows what traditional iscsi-target code already does for the same failure case within iscsit_get_immediate_data().

* | Target/iscsi,iser: Avoid accepting transport connections during stop stageSagi Grimberg2014-05-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the target is in stop stage, iSER transport initiates RDMA disconnects. The iSER initiator may wish to establish a new connection over the still existing network portal. In this case iSER transport should not accept and resume new RDMA connections. In order to learn that, iscsi_np is added with enabled flag so the iSER transport can check when deciding weather to accept and resume a new connection request. The iscsi_np is enabled after successful transport setup, and disabled before iscsi_np login threads are cleaned up.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RDMA CM and iSCSI target flows are asynchronous and completely uncorrelated. Relying on the fact that iscsi_accept_np will be called after CM connection request event and will wait for it is a mistake. When attempting to login to a few targets this flow is racy and unpredictable, but for parallel login to dozens of targets will race and hang every time. The correct synchronizing mechanism in this case is pending on a semaphore rather than a wait_for_event. We keep the pending interruptible for iscsi_np cleanup stage.
