2011-08-22USB option driver add PID of Huawei Vodafone K4605Andrew Bird1-2/+5
This patch adds the product ID of Huawei's Vodafone K4605 mobile broadband modem to option.c. This is necessary so that the driver gets loaded on demand without the intervention of usb_modeswitch. This has the benefit of it becoming available faster and also ensures that the option driver is not bound to a network interface that should be claimed by suitable network driver.

2011-08-22target: Convert acl_node_lock to be IRQ-disablingRoland Dreier4-40/+40
With qla2xxx, acl_node_lock is taken inside qla2xxx's hardware_lock, which is taken in hardirq context. This means acl_node_lock must become an IRQ-disabling lock; in particular this fixes lockdep warnings along the lines of ====================================================== [ INFO: HARDIRQ-safe -> HARDIRQ-unsafe lock order detected ] (&(&se_tpg->acl_node_lock)->rlock){+.....}, at: [<ffffffffa026f872>] transport_deregister_session+0x92/0x140 [target_core_mod] and this task is already holding: (&(&ha->hardware_lock)->rlock){-.-...}, at: [<ffffffffa017c5e7>] qla_tgt_stop_phase1+0x57/0x2c0 [qla2xxx] which would create a new lock dependency: (&(&ha->hardware_lock)->rlock){-.-...} -> (&(&se_tpg->acl_node_lock)->rlock){+.....} but this new dependency connects a HARDIRQ-irq-safe lock: (&(&ha->hardware_lock)->rlock){-.-...} to a HARDIRQ-irq-unsafe lock: (&(&se_tpg->acl_node_lock)->rlock){+.....} Signed-off-by: Roland Dreier <[email protected]> Signed-off-by: Nicholas Bellinger <[email protected]>
2011-08-22target: Make locking in transport_deregister_session() IRQ safeRoland Dreier1-6/+7
At least the tcm_qla2xxx fabric driver calls into transport_deregister_session() while holding an IRQ-disabled spinlock, so the inner locking needs to use spin_lock_irqsave() instead of spin_lock_bh(). This fixes warnings seen with tcm_qla2xxx like: WARNING: at kernel/softirq.c:159 local_bh_enable_ip+0x98/0xb0() Call Trace: [<ffffffff8104e65f>] warn_slowpath_common+0x7f/0xc0 [<ffffffff8104e6ba>] warn_slowpath_null+0x1a/0x20 [<ffffffff81055368>] local_bh_enable_ip+0x98/0xb0 [<ffffffff814d5284>] _raw_spin_unlock_bh+0x14/0x20 [<ffffffffa027b7f6>] transport_deregister_session+0x96/0x180 [target_core_mod] [<ffffffffa00f7731>] tcm_qla2xxx_free_session+0xd1/0x170 [tcm_qla2xxx] [<ffffffffa01b9173>] qla_tgt_sess_put+0xc3/0x140 [qla2xxx] [<ffffffffa01bf40f>] qla_tgt_stop_phase1+0x8f/0x2c0 [qla2xxx] [<ffffffffa00f735e>] tcm_qla2xxx_tpg_store_enable+0x6e/0xd0 [tcm_qla2xxx] [<ffffffffa026ca29>] target_fabric_tpg_attr_store+0x39/0x40 [target_core_mod] [<ffffffffa00a575d>] configfs_write_file+0xbd/0x120 [configfs] [<ffffffff811464a6>] vfs_write+0xc6/0x180 [<ffffffff811467c1>] sys_write+0x51/0x90 [<ffffffff814dd382>] system_call_fastpath+0x16/0x1b Signed-off-by: Roland Dreier <[email protected]> Signed-off-by: Nicholas Bellinger <[email protected]>

2011-08-22iscsi-target: Fix iscsit_allocate_se_cmd_for_tmr failure path bugsDan Carpenter1-3/+1
This patch fixes two bugs in allocation failure handling in iscsit_allocate_se_cmd_for_tmr(): This first reported by DanC is a free-after call to transport_free_se_cmd(), this patch drops the transport_free_se_cmd() call all together, as iscsit_release_cmd() will release existing allocations as expected. The second is a bug where iscsi_cmd_t was being leaked on a cmd->tmr_req allocation failure, so make this jump to iscsit_release_cmd() as well.

2011-08-22target: Fix task SGL chaining breakage with transport_allocate_data_tasksNicholas Bellinger1-13/+21
This patch fixes two bugs associated with transport_do_task_sg_chain() operation where transport_allocate_data_tasks() was incorrectly setting task_padded_sg for all tasks, and causing bogus task->task_sg_nents assignments + OOPsen with fabrics depending upon this code. The first bit here adds a task_sg_nents_padded check in transport_allocate_data_tasks() to include an extra SGL vector when necessary for tasks that expect to be linked using sg_chain(). The second change involves making transport_do_task_sg_chain() properly account for the extra SGL vector when task->task_padded_sg is set for the non trailing ->task_sg or single ->task_sg allocations. Note this patch also removes the BUG_ON(!task->task_padded_sg) check within transport_do_task_sg_chain() as we expect this to happen normally with the updated logic in transport_allocate_data_tasks(), along with being bogus for CONTROL_SG_IO_CDB type payloads. So far this bugfix has been tested with tcm_qla2xxx and iblock backends in (task_count > 1)( and (task_count == 1) operation.

2011-08-22target: Fix task count > 1 handling breakage and use max_sector page alignmentNicholas Bellinger2-2/+33
This patch addresses recent breakage with multiple se_task (task_count > 1) operation following backend dev->se_sub_dev->se_dev_attrib.max_sectors in new transport_allocate_data_tasks() code. The initial bug here was a bogus task->task_sg_nents assignment in transport_allocate_data_tasks() based on the passed parameter, which now uses DIV_ROUND_UP(task_size, PAGE_SIZE) to determine the proper number of per task SGL entries for the (task_count > 1) case. This also means we now need to enforce a PAGE_SIZE aligned max_sector count value for this to work as expected without bringing back the pre v3.1 transport_map_mem_to_sg() logic to handle SGL offsets across multiple tasks. So this patch adds se_dev_align_max_sectors() to round down max_sectors as necessary to ensure this alignment via se_dev_set_default_attribs() and se_dev_align_max_sectors() and keeps it simple for (task_count > 1) operation. So far this bugfix has been tested with (task_count > 1) operation using iscsi-target and iblock backends.

2011-08-22target: Add missing DATA_SG_IO transport_cmd_get_valid_sectors checkNicholas Bellinger1-7/+8
This patch adds the missing transport_cmd_get_valid_sectors() check for SCF_SCSI_DATA_SG_IO_CDB type payloads to ensure that a received LBA + range does not exeed past the end of associated backend struct se_device. This patch also fixes a bug in the failure path of transport_new_cmd_obj() where this check can fail, so change to use a signed 'rc' and return '-EINVAL' to signal proper transport_generic_request_failure() handling. Signed-off-by: Nicholas Bellinger <[email protected]>
2011-08-22target: Fix SYNCHRONIZE_CACHE zero LBA + range breakageNicholas Bellinger1-7/+7
This patch fixes a SYNCHRONIZE_CACHE CDB handling bug with IBLOCK/FILEIO backends where transport_cmd_get_valid_sectors() was incorrectly rejecting a zero LBA + range CDB from being processed, and returning CHECK_CONDITION. This includes changing transport_cmd_get_valid_sectors() to return '0' on success and '-EINVAL' on failure (this makes more sense than sectors), and to only check transport_cmd_get_valid_sectors() when a non zero LBA + range SYNCHRONIZE_CACHE operation has been receieved for the non passthrough case.

2011-08-22target: Remove duplicate task completions in transport_emulate_control_cdbNicholas Bellinger1-6/+8
This patch removes a duplicate set of transport_complete_task() calls in target_emulate_unmap() and target_emulate_write_same() as the completion call is already done within transport_emulate_control_cdb() This patch also adds a check in transport_emulate_control_cdb() for the existing SCF_EMULATE_CDB_ASYNC flag currently used by SYNCHRONIZE_CACHE in order to handle IMMEDIATE processing.

2011-08-22target: Fix WRITE_SAME usage with transport_get_sizeNicholas Bellinger1-3/+3
For all flavours of WRITE_SAME, we only expect to handle a single block of data-out buffer payload, regardless of the number of logical blocks presented in the CDB. This patch changes all flavours of WRITE_SAME in transport_generic_cmd_sequencer() to pass '1' into transport_get_size() instead of the extracted 'sectors' to properly handle the default usage of sg_write_same without the --xferlen parameter.

2011-08-22target: Add WRITE_SAME (10) parsing and refactor passthrough checksNicholas Bellinger2-57/+73
This patch adds initial WRITE_SAME (10) w/ UNMAP=1 support following updates in sbcr26 to allow UNMAP=1 for the non 16 + 32 byte CDB case. It also refactors current pSCSI passthrough passthrough checks into target_check_write_same_discard() ahead of UNMAP=0 w/ write payload support into target_core_iblock.c. This includes the support for handling WRITE_SAME in transport_emulate_control_cdb(), and converts target_emulate_write_same to accept num_blocks directly for WRITE_SAME, WRITE_SAME_16 and WRITE_SAME_32.

2011-08-22target: Fix write payload exception handling with ->new_cmd_mapNicholas Bellinger1-2/+8
This patch fixes a bug for fabrics using tfo->new_cmd_map() that are expect transport_generic_request_failure() to be calling transport_send_check_condition_and_sense() for both READ and WRITE, instead of only for READ exceptions.

2011-08-22iscsi-target: Fix leak on failure in iscsi_copy_param_list()Jesper Juhl1-27/+16
We leak memory if the allocations for 'new_param->name' or 'new_param->value' fail in iscsi_target_parameters.c::iscsi_copy_param_list() We also do a lot of variable assignments that are completely pointless if the allocations fail. So, let's move the allocations before the assignments and also make sure that we free whatever was allocated to one if the allocation fail. There's also some small CodingStyle fixups in there (curly braces on both branches of if statement, only one variable per line) since I was in the area anyway. And finally, error messages in the function are put on a single line for easy grep'abillity. Signed-off-by: Jesper Juhl <[email protected]> Signed-off-by: Nicholas Bellinger <[email protected]>

2011-08-22target: Make standard INQUIRY return 'not connected' for tpg_virt_lun0Nicholas Bellinger4-6/+27
This patch changes target_emulate_inquiry_std() to set the 'not connected' (0x35) bit in standard INQUIRY response data when we are processing a request to a virtual LUN=0 mapping from struct se_device *g_lun0_dev that have been setup for us in transport_lookup_cmd_lun(). This addresses an issue where qla2xxx FC clients need to be able to create demo-mode I_T FC Nexuses by default, but should not be exposing the default set of TPG LUNs to all FC clients. This includes adding an new optional target_core_fabric_ops->tpg_check_demo_mode_login_only() caller to allow demo_mode nexuses to skip the old default of bulding a demo-mode MappedLUNs list via core_tpg_add_node_to_devs().

Due to some recent optimization done in the way the mac address bytes are written into the OTP memory, some AR9485 chipsets were forced to use the first byte from the eeprom template and the remaining bytes are read from OTP. AR9485 happens to use generic eeprom template which has 0x1 as the first byte causes issues in bringing up the card. So fixed the eeprom template accordingly to address the issue.

2011-08-22Input: ad714x - read the interrupt status registers in a rowMichael Hennerich4-41/+49
The interrupt status registers should be read in row to avoid invalid data. Alter "read" method for both bus options to allow reading several registers in a row and make sure we read interrupt status registers properly. Read sequence saves 50% of bus transactions compared to single register reads. So use it also for the result registers, which are also located in a row. Also update copyright notice.

2011-08-22Input: ad714x - use DMA-safe buffers for spi_write()Dmitry Torokhov4-103/+131
spi_write() requires use of DMA-safe (cacheline aligned) buffers. Also use the same buffers when reading data since to avoid extra locking and potential memory allocation in spi_write_then_read(). Acked-by: Michael Hennerich <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>

2011-08-22xen: Do not enable PV IPIs when vector callback not presentStefano Stabellini1-2/+2
Fix regression for HVM case on older (<4.1.1) hypervisors caused by commit 99bbb3a84a99cd04ab16b998b20f01a72cfa9f4f Author: Stefano Stabellini <[email protected]> Date: Thu Dec 2 17:55:10 2010 +0000 xen: PV on HVM: support PV spinlocks and IPIs This change replaced the SMP operations with event based handlers without taking into account that this only works when the hypervisor supports callback vectors. This causes unexplainable hangs early on boot for HVM guests with more than one CPU.
