keep alives are disabled due to fd_flags set and also stop updating keep alive values in that case. Update select fcf time only if fcf is not already selected or select time is not already determined from parse adv, and then have select time cleared only once after fcf is selected. Changed deadline check to time_after_eq() from time_after() since now next timeout will be on exact 2.5 times FKA followed by first advertisement. Signed-off-by:

[This patch has several improvements to the code in the fip timers. It hasn't been tested yet. I'm sending it out for review. Vasu, perhaps you can merge this with your patch and test it together.] The current code allows an advertisement to be used even if it has been 3 times the FCF keep-alive advertisement period (FKA) since one was received from that FCF. The spec. calls for 2.5 times FKA. Fix this and make sure we detect missed keep-alives promptly. Signed-off-by:

Resubmitting after incorporating Joe's review comment. Unsolicited PRLO request is now handled by sending LS_ACC, and then relogin to the remote port if an N-port login session exists for that remote port. Note that this patch should be applied on top of Joe Eykholt's "Fix remote port restart problem" patch. Signed-off-by:

As per FC-LS Rev 1.62 table 46, response codes are handled as follows: 1. If the Req executed is true, PRLI is accepted. 2. If Req executed is not set, if resp code is 5, PRLI is not retried and port is logged out. 3. If resp code is anything apart from 1 or 5, PRLI is retired upto max retry count. Signed-off-by:

Host does not send discovery solicitation messages if Disc. Adv from FCF are dropped. It restarts sending solicitation only after receiving a Discovery Adv. from FCF. Fix is to restart solicitation immediately after CVL processing. Signed-off-by:

A check in fcoe_ctlr_send_keep_alive() returns if there's no port_id for the local port. This could miss a keep alive if we just did a host reset and have logged off and will log back in. Return only if we are doing the port keep alive, in which case we need to be logged in. Signed-off-by:

A problem was found where the call to scsi_add_device() fails intermittently for an adapter. This is caused when __scsi_add_device() returns -ENODEV as a result of not calling scsi_probe_and_add_lun() since the call to scsi_host_scan_allowed() fails. scsi_host_scan_allowed() fails because the adapter state is set to SHOST_RECOVERY instead of SHOST_RUNNING. The state of the adapter is being set to SHOST_RECOVERY by scsi_eh_scmd_add() during error handling. This problem is avoided by moving the setting of the allow_restart flag to later in the device initialization sequence. This prevents further error handling if we get a NOT_READY response from a TUR command by causing scsi_check_sense() to return SUCCESS. Therefore, scsi_eh_scmd_add() will not run and the adapter state will remain as SHOST_RUNNING. Signed-off-by:

This patch fixes 4 bugs in the connection connect/disconnect cleanup path. 1. If beiscsi_open_conn fails beiscsi_free_ep was always being called, and if beiscsi_open_conn failed because beiscsi_get_cid failed then we would free an unallocated cid. 2. If beiscsi_ep_connect failed due to a beiscsi_open_conn failure it was leaking iscsi_endpoints. 3. beiscsi_ep_disconnect was leaking iscsi_endpoints. beiscsi_ep_disconnect should free the iscsi_endpoint. We cannot do it in beiscsi_conn_stop because that is only called for iscsi connection cleanup. If beiscsi_ep_connect returns success, but then the poll function fails or the connect times out then beiscsi_ep_disconnect will be called to clean up the ep. The conn_stop callout will not be called in that path. 4. beiscsi_conn_stop was freeing the iscsi_endpoint then accessing it a couple lines later. Signed-off-by:

A change in the hardware design of the chip for the new adapters changes the default endianness of MMIO operations. This patch adds a register definition which when written to with a predefined value will change the endianness back to what the driver expects. This patch also fixes two problems found during testing. First, the first reserved field in the ipr_hostrcb64_fabirc_desc structure only reserved one byte. The correct amount to reserve is 2 bytes. Second, the reserved field of the ipr_hostrcb64_error structure only reserved 2 bytes. The correct amount to reserve is 16 bytes. Signed-off-by:

The function adpt_i2o_post_wait is called from several places, in some of which, such as adpt_abort, a lock may be held. The functions adpt_i2o_reparse_lct and adpt_i2o_lct_get are called from several places, including adpt_rescan where a lock may be held. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @gfp exists@ identifier fn; position p; @@ fn(...) { ... when != spin_unlock_irqrestore when any GFP_KERNEL@p ... when any } @locked@ identifier gfp.fn; @@ spin_lock_irqsave(...) ... when != spin_unlock_irqrestore fn(...) @depends on locked@ position gfp.p; @@ - GFP_KERNEL@p + GFP_ATOMIC // </smpl> Signed-off-by:

Outstanding mailbox commands, have no way to recover on f/w hung, and we timeout on waiting for mbx response. This in turn affects the recovery process as follows: - We might already be in dpc while waiting for mbx to complete, so recovery for that pci function will never get invoked. Reset Timeout (10 sec) is far less than mbx timeout (30 sec). - Other mbx cmds will get stuck due to serial mbx access. Solution is to identify fw-hung scenario and handle outstanding mbx commands to have an early-exit instead of waiting for response. Other mbx commands waiting for access will also do an early-exit if fw-hung is still applicable. Signed-off-by:
