2013-10-25[SCSI] be2iscsi: Fix repeated issue of MAC ADDR get IOCTLJayamohan Kallickal3-1/+4
Storing MAC ADDR of each function in it's priv structure to avoid issuing MAC_ADDR get IOCTL. Based on a flag set/unset it's decided if MAC_ADDR is stored in priv structure or IOCTL needs to be issued.

2013-10-25[SCSI] BNX2FC: hung task timeout warning observed when rmmod bnx2x with ↵Eddie Wai1-15/+44
active FCoE targets [v2] - removed the interface->enabled flag setting which prevented the fcoe ctlr link from being brought back up after a MTU change A rtnl_lock deadlock was observed from the rmmod thread where it tries to unregister the fcoe_ctlr device. This unregistration triggered a flush of the sysfs queue of the associated ctlr and led to a call to the set_fcoe_ctlr_enabled routine. This will eventually propagate down to call the bnx2fc_disable routine and contented for the rtnl_lock in the same context. This patch creates a subset of the bnx2fc_enable/disable routine which removes the unnecesary rtnl_lock and the bnx2fc_dev_lock acquisition from the set_fcoe_ctlr_enabled path. kernel: INFO: task rmmod:7874 blocked for more than 120 seconds. kernel: Tainted: G W --------------- 2.6.32-415.0.1.el6.x86_64 #1 kernel: "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. kernel: rmmod D 000000000000000f 0 7874 6518 0x00000080 kernel: ffff88022158f7d8 0000000000000086 0000000000000000 0000000000000000 kernel: ffff88023fe72600 ffff88043c74d410 ffff88043c74d400 ffff88043c74d000 kernel: ffff88021ecbe5f8 ffff88022158ffd8 000000000000fbc8 ffff88021ecbe5f8 kernel: Call Trace: kernel: [<ffffffff81525985>] schedule_timeout+0x215/0x2e0 kernel: [<ffffffff810680c0>] ? pick_next_task_fair+0xd0/0x130 kernel: [<ffffffff81524858>] ? schedule+0x178/0x3b2 kernel: [<ffffffff81525603>] wait_for_common+0x123/0x180 kernel: [<ffffffff81066b40>] ? default_wake_function+0x0/0x20 kernel: [<ffffffff811a486e>] ? ifind_fast+0x5e/0xb0 kernel: [<ffffffff8152571d>] wait_for_completion+0x1d/0x20 kernel: [<ffffffff81203868>] sysfs_addrm_finish+0x228/0x270 kernel: [<ffffffff812014ab>] sysfs_hash_and_remove+0x5b/0x90 kernel: [<ffffffff812056af>] sysfs_remove_group+0x5f/0x100 kernel: [<ffffffff81367e8b>] device_remove_groups+0x3b/0x60 kernel: [<ffffffff8136811d>] device_remove_attrs+0x3d/0x90 kernel: [<ffffffff81368295>] device_del+0x125/0x1e0 kernel: [<ffffffff81368372>] device_unregister+0x22/0x60 kernel: [<ffffffffa038ead2>] fcoe_ctlr_device_delete+0xe2/0xf4 [libfcoe] kernel: [<ffffffffa03c43cb>] bnx2fc_interface_release+0x5b/0x90 [bnx2fc] kernel: [<ffffffffa03c4370>] ? bnx2fc_interface_release+0x0/0x90 [bnx2fc] kernel: [<ffffffff812835e7>] kref_put+0x37/0x70 kernel: [<ffffffffa03c4192>] __bnx2fc_destroy+0x72/0xa0 [bnx2fc] kernel: [<ffffffffa03c5265>] bnx2fc_ulp_exit+0xf5/0x160 [bnx2fc] <- got bnx2fc_dev_lock mutex_lock kernel: [<ffffffffa03b03c6>] cnic_ulp_exit+0xb6/0xc0 [cnic] kernel: [<ffffffffa03b5418>] cnic_netdev_event+0x368/0x370 [cnic] kernel: [<ffffffffa038c56c>] ? fcoe_del_netdev_mapping+0x8c/0xa0 [libfcoe] kernel: [<ffffffff8152a6e5>] notifier_call_chain+0x55/0x80 kernel: [<ffffffff810a0a46>] raw_notifier_call_chain+0x16/0x20 kernel: [<ffffffff81459beb>] call_netdevice_notifiers+0x1b/0x20 kernel: [<ffffffff8145ab34>] rollback_registered_many+0x154/0x280 kernel: [<ffffffff8145ad08>] rollback_registered+0x38/0x50 kernel: [<ffffffff8145ad78>] unregister_netdevice_queue+0x58/0xa0 kernel: [<ffffffff8145add0>] unregister_netdevice+0x10/0x20 kernel: [<ffffffff8145adfe>] unregister_netdev+0x1e/0x30 <- got rtnl_lock!!!!!!!!! kernel: [<ffffffffa0122278>] __bnx2x_remove+0x48/0x270 [bnx2x] <- got & rel rtnl_lock kernel: [<ffffffffa0122554>] bnx2x_remove_one+0x44/0x80 [bnx2x] kernel: [<ffffffff812a3af7>] pci_device_remove+0x37/0x70 kernel: [<ffffffff8136b2ef>] __device_release_driver+0x6f/0xe0 kernel: [<ffffffff8136b428>] driver_detach+0xc8/0xd0 kernel: [<ffffffff8136a22e>] bus_remove_driver+0x8e/0x110 kernel: [<ffffffff8136bc12>] driver_unregister+0x62/0xa0 kernel: [<ffffffff812a3e04>] pci_unregister_driver+0x44/0xb0 kernel: [<ffffffffa0191954>] bnx2x_cleanup+0x18/0x73 [bnx2x] kernel: [<ffffffff810b8be4>] sys_delete_module+0x194/0x260 kernel: [<ffffffff810e1347>] ? audit_syscall_entry+0x1d7/0x200 kernel: [<ffffffff8100b072>] system_call_fastpath+0x16/0x1b Signed-off-by: Eddie Wai <[email protected]> Signed-off-by: James Bottomley <[email protected]>
2013-10-25[SCSI] bnx2fc: Fixed a SCSI CMD cmpl race condition between ABTS and CLEANUPEddie Wai1-0/+6
In the case when a SCSI_CMD times out, bnx2fc will initiate the sending of the ABTS. However, if the SCSI layer's SCSI command timer also times out, it'll instantiate a task abort of the same xid. The race condition this patch tries to fix is as follows: SCSI_CMD timeout (20s) thread 1 thread 2 send ABTS rx ABTS cmpl task abort_eh explicit LOGO since ABTS was engaged CLEANUP cmpl SCSI_CMD cmpl (ABTS cmpl) instantiate RRQ wait 10s attempt to send RRQ (because of LOGO, it wouldn't continue) Note that there is no call to scsi_done for this SCSI_CMD cmpletion in this path. The patch changes the path of execution to call scsi_done immediately instead of instantiating the RRQ. Signed-off-by: Eddie Wai <[email protected]> Signed-off-by: James Bottomley <[email protected]>

2013-10-23[SCSI] sd: call blk_pm_runtime_init before add_diskAaron Lu1-1/+1
Sujit has found a race condition that would make q->nr_pending unbalanced, it occurs as Sujit explained: " sd_probe_async() -> add_disk() -> disk_add_event() -> schedule(disk_events_workfn) sd_revalidate_disk() blk_pm_runtime_init() return; Let's say the disk_events_workfn() calls sd_check_events() which tries to send test_unit_ready() and because of sd_revalidate_disk() trying to send another commands the test_unit_ready() might be re-queued as the tagged command queuing is disabled. So the race condition is - Thread 1 | Thread 2 sd_revalidate_disk() | sd_check_events() ...nr_pending = 0 as q->dev = NULL| scsi_queue_insert() blk_runtime_pm_init() | blk_pm_requeue_request() -> | nr_pending = -1 since | q->dev != NULL " The problem is, the test_unit_ready request doesn't get counted the first time it is queued, so the later decrement of q->nr_pending in blk_pm_requeue_request makes it unbalanced. Fix this by calling blk_pm_runtime_init before add_disk so that all requests initiated there will all be counted.

2013-10-11libfcoe: Make fcoe_sysfs optional / fix fnic NULL exceptionRobert Love3-31/+65
fnic doesn't use any of the create/destroy/enable/disable interfaces either from the (legacy) module paramaters or the (new) fcoe_sysfs interfaces. When fcoe_sysfs was introduced fnic wasn't changed since it wasn't using the interfaces. libfcoe incorrectly assumed that that all of its users were using fcoe_sysfs and when adding and deleting FCFs would assume the existance of a fcoe_ctlr_device. fnic was not allocating this structure because it doesn't care about the standard user interfaces (fnic starts on link only). If/When libfcoe tried to use the fcoe_ctlr_device's lock for the first time a NULL pointer exception would be triggered. Since fnic doesn't care about sysfs or user interfaces, the solution is to drop libfcoe's assumption that all drivers are using fcoe_sysfs. This patch accomplishes this by changing some of the structure relationships. We need a way to determine when a LLD is using fcoe_sysfs or not and we can do that by checking for the existance of the fcoe_ctlr_device. Prior to this patch, it was assumed that the fcoe_ctlr structure was allocated with the fcoe_ctlr_device and immediately followed it in memory. To reach the fcoe_ctlr_device we would simply go back in memory from the fcoe_ctlr to get the fcoe_ctlr_device. Since fnic doesn't allocate the fcoe_ctlr_device, we cannot keep that assumption. This patch adds a pointer from the fcoe_ctlr to the fcoe_ctlr_device. For bnx2fc and fcoe we will continue to allocate the two structures together, but then we'll set the ctlr->cdev pointer to point at the fcoe_ctlr_device. fnic will not change and will continue to allocate the fcoe_ctlr itself, and ctlr->cdev will remain NULL. When libfcoe adds fcoe_fcf's to the fcoe_ctlr it will check if ctlr->cdev is set and only if so will it continue to interact with fcoe_sysfs.
