| * RDMA/nes: Fix stale ARP issueFaisal Latif2009-12-09
| | | | | | | | | | | | | | | | | | | | | | When the remote node's ethernet address changes, the connection keeps trying to connect using the old address. The connection wil continue failing until the driver is unloaded and loaded again (eiter reboot or rmmod). Fix this by checking that the NIC has the correct address before starting a connection.

| * RDMA/nes: FIN during MPA startup causes timeoutFaisal Latif2009-12-09
| | | | | | | | | | | | | | | | | | | | | | A FIN that is received during an MPA start up sequence causes a timeout in iwcm.c. The connection has not been completely closed so the iwcm code is waiting for resources to be cleaned up. This closes the connection so everything cleans up correctly.

| * RDMA/nes: Free kmap() resourcesFaisal Latif2009-12-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We fail when creating many qps as kmap() fails for sq_vbase. Fix this by doing kunmap() as soon as we are done with sq_vbase. We do kunmap() in one of the locations below: (1) nes_destroy_qp() (2) nes_accept() (3) nes_connect_event We keep a flag to avoid multiple calls to kunmap().

| * RDMA/nes: Check for zero STagFaisal Latif2009-12-09
| | | | | | | | | | | | | | | | | | | | STags are generated randomly but the driver does not correctly prevent a zero STag. Using STag zero is privileged and causes a user space application to fail. This change prevents the driver from trying to allocate a zero STag. Signed-off-by: Faisal Latif <faisal.latif@intel.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
| * RDMA/nes: Fix Xansation test crash on cm_node ref_countFaisal Latif2009-12-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While running a Xansation test, an active side node crashed. The problem started on the passive side, which generated an STtag that was 0. The passive side sent a TERMINATE instead of an MPA REJECT msg. The active side, receives TERMINATE and sends connect_err() and set the cm_node state to CLOSED. The passive side sends FIN + ACK after TERMINATE. Active side ends up in handle_ack_pkt() and send_reset(). send_reset() consumes 1 cm_node's ref_count. Because the cm_node is in CLOSED state, which means that cm_node will be destroyed after completion of the connect_err() indication, CM will crash after send_reset().

| * RDMA/nes: Abnormal listener exit causes loopback node crashFaisal Latif2009-12-09
| | | | | | | | | | | | | | | | | | | | | | When the listener is destroyed for a loopback connection, the listener node gets a reset event. This causes a crash as the listener is not expecting a reset event. Code review of cm_event_reset() during debugging showed the cm_id ref count is incremented after calling its event handler and not before.

| * RDMA/nes: Fix crash in nes_accept()Faisal Latif2009-12-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While running IMP_EXT's window test, we saw a crash in nes_accept(). Here is the sequence of what happened: (1) In MVAPICH2, connect request is received for port #0. FIX: Add a nes_connect() check to make sure local or remote tcp port is not 0. (2) Remote node's (passive) TCP stack sends a reset when it gets a connect request because of port = 0. Active side set the connect error to IW_CM_EVENT_STATUS_REJECTED when it received the RST from remote node. FIX: The corect error code is -ECONNRESET. (3) Wrong error code of IW_CM_EVENT_STATUS_REJECTED causes the core to destroy its listener ports. Here there are connections that may have sent an MPA request up and waiting for accept or reject. But the listener and its cm_nodes have been freed already causing the crash noticed. FIX: The cm_node is freed only if its state is not NES_CM_STATE_MPAREQ_RCVD. If cm_node's state is NES_CM_STATE_MPAREQ_RCVD then its new state is set to NES_CM_STATE_LISTENER_DESTROYED and it is not freed. When nes_accept() or nes_reject() is received, its state is checked for NES_CM_STATE_LISTENER_DESTROYED and in this case the cm_node is freed and error is returned.

| | | | | | | | | | | | | | | | | | | | During testing of REJECT connection error handling, we saw that the cm_id resources are not released.

| | | | | | | | | | | | | | | | | | | | | | | | Running large cluster setup, we are hanging after many hours of testing. Fixing this required going over the code and making sure the rexmit entry was properly removed based on the cm_node's state and packet received. Also when receiving a FIN packet, check seq# and make sure there were no errors before calling handle_fin(). Following are the changes done in nes_cm.c: * handle_ack_pkt() needs to return error value, so in case of error, handle_fin() is not called. Some cleanup done while going over the code. * handle_rst_pkt(), handling of cm_node's NES_CM_STATE_LAST_ACK is missing. * process_packet(), in case of FIN only packet is received, call check_seq() before processing. * in handle_fin_pkt(), we are calling cleanup_retrans_entry() for all conditions, even if the packets need to be dropped.
