target: fix destroy device in target_configure_device

2018-01-18T09:21:11Z

After dev->transport->configure_device succeeds, target_configure_device exits abnormally, dev_flags has not set DF_CONFIGURED yet, does not call destroy_device function in free_device. Signed-off-by: tangwenji Acked-by: Mike Christie Signed-off-by: Nicholas Bellinger

target: Fix cmd size for PR-OUT in passthrough_parse_cdb

2017-07-10T03:58:49Z

The cmd size should be 4bytes form byte5 to byte8 when CDB opcode is PERSISTENT_RESERVE_OUT in SPC3 and SPC4 (Also fix up the same in spc_parse_cdb - MNC) Signed-off-by: Tang Wenji Signed-off-by: Nicholas Bellinger

target: Use macro for WRITE_VERIFY_32 operation codes

2017-07-07T06:11:49Z

Add WRITE_VERIFY_32 definition to scsi prototypes and use this macro definition isntead of the hard coded value. (Drop WRITE_VERIFY_16 that's already part of another patch - nab) Signed-off-by: Damien Le Moal Signed-off-by: Nicholas Bellinger

target: make device_mutex and device_list static

2017-07-07T06:11:44Z

Variables device_mutex and device_list static are local to the source, so make them static. Cleans up sparse warnings: "symbol 'device_list' was not declared. Should it be static?" "symbol 'device_mutex' was not declared. Should it be static?" Signed-off-by: Colin Ian King Signed-off-by: Nicholas Bellinger

target: remove g_device_list

2017-07-07T06:11:41Z

g_device_list is no longer needed because we now use the idr code for lookups and seaches. Signed-off-by: Mike Christie Reviewed-by: Bart Van Assche Signed-off-by: Nicholas Bellinger

target: add helper to iterate over devices

2017-07-07T06:11:39Z

This adds a wrapper around idr_for_each so the xcopy code can loop over the devices in the next patch. Signed-off-by: Mike Christie Reviewed-by: Bart Van Assche Signed-off-by: Nicholas Bellinger

target: add helper to find se_device by dev_index

2017-07-07T06:11:38Z

This adds a helper to find a se_device by dev_index. It will be used in the next patches so tcmu's netlink interface can execute commands on specific devices. Signed-off-by: Mike Christie Reviewed-by: Bart Van Assche Signed-off-by: Nicholas Bellinger

target: use idr for se_device dev index

2017-07-07T06:11:37Z

In the next patches we will add tcmu netlink support that allows userspace to send commands to target_core_user. To execute operations on a se_device/tcmu_dev we need to be able to look up a dev by any old id. This patch replaces the se_device->dev_index with a idr created id. The next patches will also remove the g_device_list and replace it with the idr. Signed-off-by: Mike Christie Signed-off-by: Nicholas Bellinger

target: break up free_device callback

2017-07-07T06:11:37Z

With this patch free_device is now used to free what is allocated in the alloc_device callback and destroy_device tears down the resources that are setup in the configure_device callback. This patch will be needed in the next patch where tcmu needs to be able to look up the device in the destroy callback.

target: Use {get,put}_unaligned_be*() instead of open coding these functions

2017-07-07T05:57:59Z

Introduce the function get_unaligned_be24(). Use {get,put}_unaligned_be*() where appropriate. This patch does not change any functionality.
