2016-11-18cxgb4: Allocate Tx queues dynamicallyHariprasad Shenai1-0/+1
Allocate resources dynamically for Upper layer driver's (ULD) like cxgbit, iw_cxgb4, cxgb4i and chcr. The resources allocated include Tx queues which are allocated when ULD register with cxgb4 driver and freed while un-registering. The Tx queues which are shared by ULD shall be allocated by first registering driver and un-allocated by last unregistering driver.

2016-07-20target: Fix race between iscsi-target connection shutdown + ABORT_TASKNicholas Bellinger1-6/+16
This patch fixes a race in iscsit_release_commands_from_conn() -> iscsit_free_cmd() -> transport_generic_free_cmd() + wait_for_tasks=1, where CMD_T_FABRIC_STOP could end up being set after the final kref_put() is called from core_tmr_abort_task() context. This results in transport_generic_free_cmd() blocking indefinately on se_cmd->cmd_wait_comp, because the target_release_cmd_kref() check for CMD_T_FABRIC_STOP returns false. To address this bug, make iscsit_release_commands_from_conn() do list_splice and set CMD_T_FABRIC_STOP early while holding iscsi_conn->cmd_lock. Also make iscsit_aborted_task() only remove iscsi_cmd_t if CMD_T_FABRIC_STOP has not already been set. Finally in target_release_cmd_kref(), only honor fabric_stop if CMD_T_ABORTED has been set.

2016-05-17iscsi-target: Fix early sk_data_ready LOGIN_FLAGS_READY raceNicholas Bellinger1-9/+9
There is a iscsi-target/tcp login race in LOGIN_FLAGS_READY state assignment that can result in frequent errors during iscsi discovery: "iSCSI Login negotiation failed." To address this bug, move the initial LOGIN_FLAGS_READY assignment ahead of iscsi_target_do_login() when handling the initial iscsi_target_start_negotiation() request PDU during connection login. As iscsi_target_do_login_rx() work_struct callback is clearing LOGIN_FLAGS_READ_ACTIVE after subsequent calls to iscsi_target_do_login(), the early sk_data_ready ahead of the first iscsi_target_do_login() expects LOGIN_FLAGS_READY to also be set for the initial login request PDU. As reported by Maged, this was first obsered using an MSFT initiator running across multiple VMWare host virtual machines with iscsi-target/tcp.

2016-05-10iscsi-target: graceful disconnect on invalid mapping to iovecImran Haider1-1/+8
Ensures the first page entry is within bounds. A failed check would terminate the iSCSI connection instead of causing a NULL-dereference. This violation seems to happen with certain iSCSI commands where the computed CDB length is zero but the expected transfer length is non-zero. The real problem is probably on the iSCSI initiator side since there is a discrepancy between the iSCSI header and the encapsulated CDB Opcode.

2016-05-10iscsi-target: remove usage of ->shutdown_sessionChristoph Hellwig4-23/+12

So instead remove ->shutdown and have the core call ->close_session directly, and replace all calls to target_put_session in the iSCSI target with direct calls to iscsit_close_session.
