git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending Pull SCSI target updates from Nicholas Bellinger: "It's been a busy development cycle for target-core in a number of different areas. The fabric API usage for se_node_acl allocation is now within target-core code, dropping the external API callers for all fabric drivers tree-wide. There is a new conversion to RCU hlists for se_node_acl and se_portal_group LUN mappings, that turns fast-past LUN lookup into a completely lockless code-path. It also removes the original hard-coded limitation of 256 LUNs per fabric endpoint. The configfs attributes for backends can now be shared between core and driver code, allowing existing drivers to use common code while still allowing flexibility for new backend provided attributes. The highlights include: - Merge sbc_verify_dif_* into common code (sagi) - Remove iscsi-target support for obsolete IFMarker/OFMarker (Christophe Vu-Brugier) - Add bidi support in target/user backend (ilias + vangelis + agover) - Move se_node_acl allocation into target-core code (hch) - Add crc_t10dif_update common helper (akinobu + mkp) - Handle target-core odd SGL mapping for data transfer memory (akinobu) - Move transport ID handling into target-core (hch) - Move task tag into struct se_cmd + support 64-bit tags (bart) - Convert se_node_acl->device_list[] to RCU hlist (nab + hch + paulmck) - Convert se_portal_group->tpg_lun_list[] to RCU hlist (nab + hch + paulmck) - Simplify target backend driver registration (hch) - Consolidate + simplify target backend attribute implementations (hch + nab) - Subsume se_port + t10_alua_tg_pt_gp_member into se_lun (hch) - Drop lun_sep_lock for se_lun->lun_se_dev RCU usage (hch + nab) - Drop unnecessary core_tpg_register TFO parameter (nab) - Use 64-bit LUNs tree-wide (hannes) - Drop left-over TARGET_MAX_LUNS_PER_TRANSPORT limit (hannes)" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (76 commits) target: Bump core version to v5.0 target: remove target_core_configfs.h target: remove unused TARGET_CORE_CONFIG_ROOT define target: consolidate version defines target: implement WRITE_SAME with UNMAP bit using ->execute_unmap target: simplify UNMAP handling target: replace se_cmd->execute_rw with a protocol_data field target/user: Fix inconsistent kmap_atomic/kunmap_atomic target: Send UA when changing LUN inventory target: Send UA upon LUN RESET tmr completion target: Send UA on ALUA target port group change target: Convert se_lun->lun_deve_lock to normal spinlock target: use 'se_dev_entry' when allocating UAs target: Remove 'ua_nacl' pointer from se_ua structure target_core_alua: Correct UA handling when switching states xen-scsiback: Fix compile warning for 64-bit LUN target: Remove TARGET_MAX_LUNS_PER_TRANSPORT target: use 64-bit LUNs target: Drop duplicate + unused se_dev_check_wce target: Drop unnecessary core_tpg_register TFO parameter ...

2015-06-23module: add per-module param_lockDan Streetman
Add a "param_lock" mutex to each module, and update params.c to use the correct built-in or module mutex while locking kernel params. Remove the kparam_block_sysfs_r/w() macros, replace them with direct calls to kernel_param_[un]lock(module). The kernel param code currently uses a single mutex to protect modification of any and all kernel params. While this generally works, there is one specific problem with it; a module callback function cannot safely load another module, i.e. with request_module() or even with indirect calls such as crypto_has_alg(). If the module to be loaded has any of its params configured (e.g. with a /etc/modprobe.d/* config file), then the attempt will result in a deadlock between the first module param callback waiting for modprobe, and modprobe trying to lock the single kernel param mutex to set the new module's param. This fixes that by using per-module mutexes, so that each individual module is protected against concurrent changes in its own kernel params, but is not blocked by changes to other module params. All built-in modules continue to use the built-in mutex, since they will always be loaded at runtime and references (e.g. request_module(), crypto_has_alg()) to them will never cause load-time param changing. This also simplifies the interface used by modules to block sysfs access to their params; while there are currently functions to block and unblock sysfs param access which are split up by read and write and expect a single kernel param to be passed, their actual operation is identical and applies to all params, not just the one passed to them; they simply lock and unlock the global param mutex. They are replaced with direct calls to kernel_param_[un]lock(THIS_MODULE), which locks THIS_MODULE's param_lock, or if the module is built-in, it locks the built-in mutex.

2015-06-21MIPS: Octeon: Set OHCI and EHCI MMIO byte order to match CPUBen Hutchings
The Octeon OHCI is now supported by the ohci-platform driver, and USB_OCTEON_OHCI is marked as deprecated. However, it is currently still necessary to enable it in order to select USB_OHCI_BIG_ENDIAN_MMIO. Make CPU_CAVIUM_OCTEON select that as well, so that USB_OCTEON_OHCI is really obsolete. The old ohci-octeon and ehci-octeon drivers also only enabled big-endian MMIO in case the CPU was big-endian. Make the selections of USB_EHCI_BIG_ENDIAN_MMIO and USB_OHCI_BIG_ENDIAN_MMIO conditional, to match this.

Only include SCSI initiator header files in target code that needs these header files, namely the SCSI pass-through code and the tcm_loop driver. Change SCSI_SENSE_BUFFERSIZE into TRANSPORT_SENSE_BUFFER in target code because the former is intended for initiator code and the latter for target code. With this patch the only initiator include directives in target code that remain are as follows: $ git grep -nHE 'include .scsi/(scsi.h|scsi_host.h|scsi_device.h|scsi_cmnd.h)' drivers/target drivers/infiniband/ulp/{isert,srpt} drivers/usb/gadget/legacy/tcm_*.[ch] drivers/{vhost,xen} include/{target,trace/events/target.h} drivers/target/loopback/tcm_loop.c:29:#include <scsi/scsi.h> drivers/target/loopback/tcm_loop.c:31:#include <scsi/scsi_host.h> drivers/target/loopback/tcm_loop.c:32:#include <scsi/scsi_device.h> drivers/target/loopback/tcm_loop.c:33:#include <scsi/scsi_cmnd.h> drivers/target/target_core_pscsi.c:39:#include <scsi/scsi_device.h> drivers/target/target_core_pscsi.c:40:#include <scsi/scsi_host.h> drivers/xen/xen-scsiback.c:52:#include <scsi/scsi_host.h> /* SG_ALL */ Signed-off-by: Bart Van Assche <bart.vanassche@sandisk.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: James Bottomley <JBottomley@Odin.com>
2015-06-02USB: usbtmc: add device quirk for Rigol DS6104Teunis van Beelen
Recently we purchased the Rigol DS6104 and when I try to operate it from my Linux pc, everything works well with the default usbtmc driver, except when I want to download a big datachunk like a screenshot. This bitmapfile has a size of 1152054 bytes but I receive a smaller file and no new packets can be read. When I took a look at the driver source, I found this "Rigol quirk" and I added the id of the new DS series oscilloscopes to this list. I compiled it and loaded the new driver and now everything seems to work fine. Signed-off-by: Teunis van Beelen <teuniz@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2015-05-31usb: renesas_usbhs: Don't disable the pipe if Control write status stageYoshihiro Shimoda
This patch fixes an issue that sometimes this controller is not able to complete the Control write status stage. This driver should enable DCPCTR.CCPL and PID_BUF to complete the status stage. However, if this driver detects the ctrl_stage interruption first before the control write data is received, this driver will clear the PID_BUF wrongly in the usbhsf_pio_try_pop(). To avoid this issue, this patch doesn't clear the PID_BUF in the usbhsf_pio_try_pop(). (Since also the privious code doesn't disable the PID_BUF after a control transfer was finished, this patch doesn't have any side efforts.)

2015-05-31usb: core: Fix USB 3.0 devices lost in NOTATTACHED state after a hub port resetRobert Schlabbach
Fix USB 3.0 devices lost in NOTATTACHED state after a hub port reset. Dissolve the function hub_port_finish_reset() completely and divide the actions to be taken into those which need to be done after each reset attempt and those which need to be done after the full procedure is complete, and place them in the appropriate places in hub_port_reset(). Also, remove an unneeded forward declaration of hub_port_reset(). Verbose Problem Description: USB 3.0 devices may be "lost for good" during a hub port reset. This makes Linux unable to boot from USB 3.0 devices in certain constellations of host controllers and devices, because the USB device is lost during initialization, preventing the rootfs from being mounted. The underlying problem is that in the affected constellations, during the processing inside hub_port_reset(), the hub link state goes from 0 to SS.inactive after the initial reset, and back to 0 again only after the following "warm" reset. However, hub_port_finish_reset() is called after each reset attempt and sets the state the connected USB device based on the "preliminary" status of the hot reset to USB_STATE_NOTATTACHED due to SS.inactive, yet when the following warm reset is complete and hub_port_finish_reset() is called again, its call to set the device to USB_STATE_DEFAULT is blocked by usb_set_device_state() which does not allow taking USB devices out of USB_STATE_NOTATTACHED state. Thanks to Alan Stern for guiding me to the proper solution and how to submit it.

Now instead poll the Port Link State Change (PLC) bit as the state change to U0 will set this bit.

2015-05-31usb: xhci: fix xhci locking up during hcd removeRoger Quadros
The problem seems to be that if a new device is detected while we have already removed the shared HCD, then many of the xhci operations (e.g. xhci_alloc_dev(), xhci_setup_device()) hang as command never completes. I don't think XHCI can operate without the shared HCD as we've already called xhci_halt() in xhci_only_stop_hcd() when shared HCD goes away. We need to prevent new commands from being queued not only when HCD is dying but also when HCD is halted. The following lockup was detected while testing the otg state machine.
