2015-11-09scsi: use host wide tags by defaultChristoph Hellwig1-1/+0
This patch changes the !blk-mq path to the same defaults as the blk-mq I/O path by always enabling block tagging, and always using host wide tags. We've had blk-mq available for a few releases so bugs with this mode should have been ironed out, and this ensures we get better coverage of over tagging setup over different configs.

2014-11-20bnx2fc: do not add shared skbs to the fcoe_rx_listMaurizio Lombardi1-0/+7
In some cases, the fcoe_rx_list may contains multiple instances of the same skb (the so called "shared skbs"). the bnx2fc_l2_rcv thread is a loop that extracts a skb from the list, modifies (and destroys) its content and then proceed to the next one. The problem is that if the skb is shared, the remaining instances will be corrupted. The solution is to use skb_share_check() before adding the skb to the fcoe_rx_list.

2014-09-16bnx2fc: fix incorrect DMA memory mapping in bnx2fc_unmap_sg_list()Chad Dupuis1-2/+13
This patch is based on a problem and solution from Maurizio Lombardi where bnx2fc isn't consistent in which device struct we using for DMA map and unmap operations. Make them consistent by using dma_sg_unmap in bnx2fc_unmap_sg_list like bnx2fc_map_sg.

Just like CNIC, tristate of these two modules is also dependent on IPV6. These need to be handled separately as they select CNIC, which can override tristate for CNIC from 'm' to 'y', which can cause build failures when ipv6 is compiled as a module even if CNIC's Kconfig will only 'm' or 'n' when ipv6 is compiled as a module.

In case of of error, the bnx2fc_cmd_mgr_alloc() function will call the bnx2fc_cmd_mgr_free() to perform the cleanup. The problem is that in one case the latter may try to scan some not-yet initialized lists, resulting in a kernel panic.

2014-03-20scsi, bnx2fc: Fix CPU hotplug callback registrationSrivatsa S. Bhat1-2/+10
Subsystems that want to register CPU hotplug callbacks, as well as perform initialization for the CPUs that are already online, often do it as shown below: get_online_cpus(); for_each_online_cpu(cpu) init_cpu(cpu); register_cpu_notifier(&foobar_cpu_notifier); put_online_cpus(); This is wrong, since it is prone to ABBA deadlocks involving the cpu_add_remove_lock and the cpu_hotplug.lock (when running concurrently with CPU hotplug operations). Instead, the correct and race-free way of performing the callback registration is: cpu_notifier_register_begin(); for_each_online_cpu(cpu) init_cpu(cpu); /* Note the use of the double underscored version of the API */ __register_cpu_notifier(&foobar_cpu_notifier); cpu_notifier_register_done(); Fix the bnx2fc code in scsi by using this latter form of callback registration.

The bnx2/bnx2x rings are made up of linked pages. However there is an upper limit on the page size as some the page size settings are 16-bit in the hardware/firmware interface. In the current code, some parts use BNX2_PAGE_SIZE which has a 16K upper limit and some parts use PAGE_SIZE. On archs with >= 64K PAGE_SIZE, it generates some compile warnings. Define a new CNIC_PAGE_SZIE which has an upper limit of 16K and use it consistently in all relevant parts.

2014-03-15[SCSI] bnx2fc: Fixed scsi_remove_target soft lockup when rmmod bnx2xEddie Wai1-0/+6
The problem has been identified to be a change in the scsi_remove_device path where a call to the pm_runtime_set_memalloc_noio was added when del_gendisk is called in this path. Note that the new pm routine attempts to cycle through all parent devices from the FC target device to set the memalloc_noio flag. Because of this new change, a dependency was created between the FC target device and the parent netdev device in the destroy path. In order to synchronized the destroy paths, bnx2fc has been modified to flush all destroy workqueues in the NETDEV_UNREGISTER return path. [ 4.123584] BUG: soft lockup - CPU#8 stuck for 22s!

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 <eddie.wai@broadcom.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
