2010-05-16[SCSI] fcoe: fix fcoe module ref countingVasu Dev1-1/+1
Currently fcoe module ref count is used for tracking active fcoe instances, it means each fcoe instance create increments the count while destroy dec the count. The dec is done only if fcoe instance is destroyed from /sysfs but not if destroyed due to NETDEV_UNREGISTER event. So this patch moves only module_put doing dec to common fcoe_if_destroy function, so that dec would occur on ever fcoe instance destroy.

2010-05-16[SCSI] fcoe: fix a circular locking issue with rtnl and sysfs mutexVasu Dev1-7/+34
Currently rtnl mutex is grabbed during fcoe create, destroy, enable and disable operations while sysfs s_active read mutex is already held, but simultaneously other networking events could try grabbing write s_active mutex while rtnl is already held and that is causing circular lock warning, its detailed log pasted at end. In this log, the rtnl was held before write s_active during device renaming but there are more such cases as Joe reported another instance with tg3 open at:- http://www.open-fcoe.org/pipermail/devel/2010-February/008263.html This patch fixes this issue by not waiting for rtnl mutex during fcoe ops, that means if rtnl mutex is not immediately available then restart_syscall() to allow others waiting in line to grab s_active along with rtnl mutex to finish their work first under these mutex. Currently rtnl mutex was grabbed twice during fcoe_destroy call flow, second grab was from fcoe_if_destroy called from fcoe_destroy after dropping rtnl mutex before calling fcoe_if_destroy, so instead made fcoe_if_destroy always called with rtnl mutex held to have this mutex grabbed only once in this code path. However left matching rtnl_unlock as-is in its original place as it was dropped there for good reason since very next call causes synchronous fip worker flush and if rtnl mutex is still held before flush then that would cause new circular warning between fip->recv_work and rtnl mutex, I've added detailed comment for this on fcoe_if_destroy calling and rtnl muxtes unlocking. ======================================================= [ INFO: possible circular locking dependency detected ] 2.6.33.1linux-stable-2.6.33 #1 ------------------------------------------------------- fcoemon/18823 is trying to acquire lock: (fcoe_config_mutex){+.+.+.}, at: [<ffffffffa02ba5fc>] fcoe_create+0x27/0x4f7 [fcoe] but task is already holding lock: (s_active){++++.+}, at: [<ffffffff8115ef93>] sysfs_get_active_two+0x31/0x48 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #2 (s_active){++++.+}: [<ffffffff81077bdb>] __lock_acquire+0xb73/0xd2b [<ffffffff81077e60>] lock_acquire+0xcd/0xf1 [<ffffffff8115e5df>] sysfs_deactivate+0x8b/0xe0 [<ffffffff8115edfb>] sysfs_addrm_finish+0x36/0x55 [<ffffffff8115d0cc>] sysfs_hash_and_remove+0x53/0x6a [<ffffffff8115f353>] sysfs_remove_link+0x21/0x23 [<ffffffff812b6c93>] device_rename+0x99/0xcb [<ffffffff8138dbf0>] dev_change_name+0xd5/0x1d2 [<ffffffff8138deee>] dev_ifsioc+0x201/0x2ac [<ffffffff8138e4ba>] dev_ioctl+0x521/0x632 [<ffffffff81379e43>] sock_do_ioctl+0x3d/0x47 [<ffffffff8137a254>] sock_ioctl+0x213/0x222 [<ffffffff81114614>] vfs_ioctl+0x32/0xa6 [<ffffffff81114b94>] do_vfs_ioctl+0x490/0x4d6 [<ffffffff81114c30>] sys_ioctl+0x56/0x79 [<ffffffff81009b42>] system_call_fastpath+0x16/0x1b -> #1 (rtnl_mutex){+.+.+.}: [<ffffffff81077bdb>] __lock_acquire+0xb73/0xd2b [<ffffffff81077e60>] lock_acquire+0xcd/0xf1 [<ffffffff8142f343>] __mutex_lock_common+0x4b/0x383 [<ffffffff8142f73f>] mutex_lock_nested+0x3e/0x43 [<ffffffff813959f9>] rtnl_lock+0x17/0x19 [<ffffffff8138ccae>] register_netdevice_notifier+0x1e/0x19b [<ffffffffa02580c1>] 0xffffffffa02580c1 [<ffffffff81002069>] do_one_initcall+0x5e/0x15e [<ffffffff81084094>] sys_init_module+0xd8/0x23a [<ffffffff81009b42>] system_call_fastpath+0x16/0x1b -> #0 (fcoe_config_mutex){+.+.+.}: [<ffffffff81077a85>] __lock_acquire+0xa1d/0xd2b [<ffffffff81077e60>] lock_acquire+0xcd/0xf1 [<ffffffff8142f343>] __mutex_lock_common+0x4b/0x383 [<ffffffff8142f73f>] mutex_lock_nested+0x3e/0x43 [<ffffffffa02ba5fc>] fcoe_create+0x27/0x4f7 [fcoe] [<ffffffff810635b1>] param_attr_store+0x27/0x35 [<ffffffff81063619>] module_attr_store+0x26/0x2a [<ffffffff8115dae3>] sysfs_write_file+0x108/0x144 [<ffffffff81107bd1>] vfs_write+0xae/0x10b [<ffffffff81107cee>] sys_write+0x4a/0x6e [<ffffffff81009b42>] system_call_fastpath+0x16/0x1b other info that might help us debug this: 3 locks held by fcoemon/18823: #0: (&buffer->mutex){+.+.+.}, at: [<ffffffff8115da17>] sysfs_write_file+0x3c/0x144 #1: (s_active){++++.+}, at: [<ffffffff8115ef86>] sysfs_get_active_two+0x24/0x48 #2: (s_active){++++.+}, at: [<ffffffff8115ef93>] sysfs_get_active_two+0x31/0x48 stack backtrace: Pid: 18823, comm: fcoemon Tainted: G W 2.6.33.1linux-stable-2.6.33 #1 Call Trace: [<ffffffff81076c38>] print_circular_bug+0xa8/0xb6 [<ffffffff81077a85>] __lock_acquire+0xa1d/0xd2b [<ffffffffa02ba5fc>] ? fcoe_create+0x27/0x4f7 [fcoe] [<ffffffff81077e60>] lock_acquire+0xcd/0xf1 [<ffffffffa02ba5fc>] ? fcoe_create+0x27/0x4f7 [fcoe] [<ffffffffa02ba5fc>] ? fcoe_create+0x27/0x4f7 [fcoe] [<ffffffff8142f343>] __mutex_lock_common+0x4b/0x383 [<ffffffffa02ba5fc>] ? fcoe_create+0x27/0x4f7 [fcoe] [<ffffffff8106ac70>] ? cpu_clock+0x43/0x5e [<ffffffff81074e12>] ? lockstat_clock+0x11/0x13 [<ffffffff81074e40>] ? lock_release_holdtime+0x2c/0x127 [<ffffffff8115ef93>] ? sysfs_get_active_two+0x31/0x48 [<ffffffff8142f73f>] mutex_lock_nested+0x3e/0x43 [<ffffffffa02ba5fc>] fcoe_create+0x27/0x4f7 [fcoe] [<ffffffff810635b1>] param_attr_store+0x27/0x35 [<ffffffff81063619>] module_attr_store+0x26/0x2a [<ffffffff8115dae3>] sysfs_write_file+0x108/0x144 [<ffffffff81107bd1>] vfs_write+0xae/0x10b [<ffffffff81076596>] ? trace_hardirqs_on_caller+0x125/0x150 [<ffffffff81107cee>] sys_write+0x4a/0x6e [<ffffffff81009b42>] system_call_fastpath+0x16/0x1b Signed-off-by: Vasu Dev <[email protected]> Signed-off-by: Robert Love <[email protected]> Signed-off-by: James Bottomley <[email protected]>
2010-05-16[SCSI] libfc: Move the port_id into lportRobert Love10-35/+36
This patch creates a port_id member in struct fc_lport. This allows libfc to just deal with fc_lport instances instead of calling into the fc_host to get the port_id. This change helps in only using symbols necessary for operation from the libfc structures. libfc still needs to change the fc_host_port_id() if the port_id changes so the presentation layer (scsi_transport_fc) can provide the user with the correct value, but libfc shouldn't rely on the presentation layer for operational values.

2010-05-16[SCSI] qla2xxx: ensure flash operation and host reset via sg_reset are ↵Lalit Chandivade2-1/+51
mutually exclusive The problem occurring is a hw-race where there's an outstanding read-flash operation occurring while the chip is being reset (done via an sg_reset script). After the chip is paused, the read-flash operation never completes and the DPC thread, while trying to complete the reset, is never able to recover, as the HW appears to be hung... The fix is to wait for outstanding flash operation prior to doing a sg_reset -h. And to wait for reset to complete before any flash operations. Note, during the wait, if any of the operation (reset/flash) does not complete, failure is returned to the upper layer. The upper layer either need to fail or retry.

Migrate to a consistent set of debug entries during status-IOCB handling: * group CS_TIMEOUT handling with CS_PORT_UNAVAILABLE and the like (more regrouping of common behaviour). * drop CS_DATA_OVERRUN handling as it now falls into the 'default' case (still returns DID_ERROR). * consolidate CS_RESET and CS_ABORTED handling, as we the only functional difference was a printk() (still returns DID_RESET). * dropped all the earlier inconsistent [qla_]printk()s sprinkled throught the needlessly large case-statement. Failure case I/Os are now logged with a 'standard' format: <command failure details> <command generic details> so, for example a dropped-frame is logged as: qla2xxx 0000:13:00.0: scsi(16:0:0) Dropped frame(s) detected (4000 of 4000 bytes). qla2xxx 0000:13:00.0: scsi(16:0:0) FCP command status: 0x15-0x18 (70018) \ oxid=78 ser=76 cdb=280000 len=4000 rsp_info=0 resid=0 fw_resid=4000 which should now convey all relevant information.

After that its the responsibility of the driver to relogin to devices whenever there is : * Any sort of connection failure or * KATO expires indicating target has logged out or * I/O times out etc. Signed-off-by: Vikas Chaudhary <[email protected]> Signed-off-by: Karen Higgins <[email protected]> Signed-off-by: Ravi Anand <[email protected]> Reviewed-by: Mike Christie <[email protected]> Signed-off-by: James Bottomley <[email protected]>

2010-05-02[SCSI] cxgb3i: Fix error path for module initRoland Dreier1-1/+3
If cxgb3i_pdu_init() fails, then it appears that cxgb3i_iscsi_init() will not be cleaned up, leading to the iscsi transport being left registered. Fix this by adding a call to cxgb3i_iscsi_cleanup() on the error path.

2010-05-02[SCSI] Unexport scsi/scsi.h from headers_installTom Rini1-1/+0
The scsi/scsi.h header is normally provided by the libc (and was not exported by the kernel since 2.6.24) and has been until it was re-exported with 2.6.31. The kernel version is not userspace clean and does not appear to provide anything useable in userland over the (e)glibc version.
