2014-09-23mei: simplify handling of hbm client eventsTomas Winkler
Add mei_hbm_cl_find_by_cmd handler to retrieve the destination client Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-09-23mei: wait for hbm start non-interruptibleAlexander Usyskin
We cannot handle user interrupt in context of hbm start so we only wait for time out which is reasonably short. 1. Add kdoc 2. Rename state to better reflect its function 3.

2014-09-23mei: revamp connect and disconnect response handlingTomas Winkler
Both responses have same flow only the client status update is different. We introduce handler mei_hbm_cl_res() that handles both responses Also we use per client wait queue (cl->wait) rather then global dev->wait_recvd_msg Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2014-09-23drivers/base: Fix length checks in create_syslog_header()/dev_vprintk_emit()Ben Hutchings
snprintf() returns the number of bytes that could have been written (excluding the null), not the actual number of bytes written. Given a long enough subsystem or device name, these functions will advance beyond the end of the on-stack buffer in dev_vprintk_exit(), resulting in an information leak or stack corruption. I don't know whether such a long name is currently possible. In case snprintf() returns a value >= the buffer size, do not add structured logging information. Also WARN if this happens, so we can fix the driver or increase the buffer size. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-09-23device coredump: add new device coredump classJohannes Berg
Many devices run firmware and/or complex hardware, and most of that can have bugs. When it misbehaves, however, it is often much harder to debug than software running on the host. Introduce a "device coredump" mechanism to allow dumping internal device/firmware state through a generalized mechanism. As devices are different and information needed can vary accordingly, this doesn't prescribe a file format - it just provides mechanism to get data to be able to capture it in a generalized way (e.g. in distributions.) The dumped data will be readable in sysfs in the virtual device's data file under /sys/class/devcoredump/devcd*/. Writing to it will free the data and remove the device, as does a 5-minute timeout. Note that generalized capturing of such data may result in privacy issues, so users generally need to be involved. In order to allow certain users/system integrators/... to disable the feature at all, introduce a Kconfig option to override the drivers that would like to have the feature. For now, this provides two ways of dumping data: 1) with a vmalloc'ed area, that is then given to the subsystem and freed after retrieval or timeout 2) with a generalized reader/free function method We could/should add more options, e.g. a list of pages, since the vmalloc area is very limited on some architectures.

2014-09-23usb: hub: allow to process more usb hub events in parallelPetr Mladek
It seems that only choose_devnum() was not ready to process more hub events at the same time. All should be fine if we take bus->usb_address0_mutex there. It will make sure that more devnums will not be chosen for the given bus and the related devices at the same time.

2014-09-23usb: hub: rename khubd to hub_wq in documentation and commentsPetr Mladek
USB hub has started to use a workqueue instead of kthread. Let's update the documentation and comments here and there. This patch mostly just replaces "khubd" with "hub_wq". There are only few exceptions where the whole sentence was updated. These more complicated changes can be found in the following files: Documentation/usb/hotplug.txt drivers/net/usb/usbnet.c drivers/usb/core/hcd.c drivers/usb/host/ohci-hcd.c drivers/usb/host/xhci.c Signed-off-by: Petr Mladek <pmladek@suse.cz> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2014-09-23usb: hub: convert khubd into workqueuePetr Mladek
There is no need to have separate kthread for handling USB hub events. It is more elegant to use the workqueue framework. The workqueue is allocated as freezable because the original thread was freezable as well. Also it is allocated as ordered because the code is not ready for parallel processing of hub events, see choose_devnum(). struct usb_hub is passed via the work item. Therefore we do not need hub_event_list. Also hub_thread() is not longer needed. It would call only hub_event(). The rest of the code did manipulate the kthread and it is handled by the workqueue framework now. kick_khubd is renamed to kick_hub_wq() to make the function clear. And the protection against races is done another way, see below. hub_event_lock has been removed. It cannot longer be used to protect struct usb_hub between hub_event() and hub_disconnect(). Instead we need to get hub->kref already in kick_hub_wq(). The lock is not really needed for the other scenarios as well. queue_work() returns whether it succeeded. We could revert the needed operations accordingly. This is enough to avoid duplicity and inconsistencies. Yes, the removed lock causes that there is not longer such a strong synchronization between scheduling the work and manipulating hub->disconnected. But kick_hub_wq() must never be called together with hub_disconnect() otherwise even the original code would have failed. Any callers are responsible for this. Therefore the only problem is that hub_disconnect() could be called in parallel with hub_event(). But this was possible even in the past. struct usb_hub is still guarded by hub->kref and released in hub_events() when needed. Note that the source file is still full of the obsolete "khubd" strings. Let's remove them in a follow up patch. This patch already is complex enough. Thanks a lot Alan Stern <stern@rowland.harvard.edu> for code review, many useful tips and guidance. Also thanks to Tejun Heo <tj@kernel.org> for hints how to allocate the workqueue.

2014-09-23usb: hub: rename hub_events() to hub_event() and handle only one event therePetr Mladek
We would like to convert khubd kthread to a workqueue. As a result hub_events() will handle only one event per call. In fact, we could do this already now because there is another cycle in hub_thread(). It calls hub_events() until hub_event_list is empty. This patch renames the function to hub_event(), removes the while cycle, and renames the goto targets from loop* to out*. When touching the code, it fixes also formatting of dev_err() and dev_dbg() calls to make checkpatch.pl happy :-) Signed-off-by: Petr Mladek <pmladek@suse.cz> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-09-23usb: hub: keep hub->dev reference all the time when struct usb_hub livesPetr Mladek
This is just a small optimization of the fix from the commit c605f3cdff53a743f6 ("usb: hub: take hub->hdev reference when processing from eventlist). We do not need to take the reference for each event. Instead we could get it when struct usb_hub is allocated and put it when it is released. By other words, we could handle it the same way as the reference for hub->intfdev. The motivation is that it will make the life easier when switching from khubd kthread to a workqueue.

2014-09-23storage: Add quirk for another SCM-based USB-SCSI converterMark Knibbs
There is apparently another SCM USB-SCSI converter with ID 04E6:000F. It is listed along with 04E6:000B in the Windows INF file for the Startech ICUSBSCSI2 as "eUSB SCSI Adapter (Bus Powered)". The quirk allows devices with SCSI ID other than 0 to be accessed. Also make a couple of existing SCM product IDs lower case to be consistent with other entries.

2014-09-23storage: Add quirks for Castlewood and Double-H USB-SCSI convertersMark Knibbs
Castlewood Systems supplied various models of USB-SCSI converter with their ORB external removable-media drive. The ORB Windows and Macintosh drivers support six USB IDs: 084B:A001 [VID 084B is Castlewood Systems] 04E6:0002 (*) ORB USB Smart Cable P/N 88205-001 (generic SCM ID) 2027:A001 Double-H Technology DH-2000SC 1822:0001 (*) Ariston iConnect/iSCSI 07AF:0004 (*) Microtech XpressSCSI (25-pin) 07AF:0005 (*) Microtech XpressSCSI (50-pin) *: quirk already in unusual-devs.h [Apparently the official VID for Double-H Technology is 0x07EB = 2027 decimal. That's another hex/decimal mix-up with these SCM-based products (in addition to the Ariston and Entrega ones). Perhaps the USB-IF informed companies of their allocated VID in decimal, but they assumed it was hex? It seems all Entrega products used VID 0x1645, not just the USB-SCSI converter.] Double-H Technology Co., Ltd. produced a USB-SCSI converter, model DH-2000SC, which is probably the one supported by the ORB drivers. Perhaps the Castlewood-bundled product had a different label or PID though? Castlewood mentioned Conmate as being one type of USB-SCSI converter. Conmate and Double-H seem related somehow; both company addresses in the same road, and at one point the Conmate web site mentioned DH-2000H4, DH-200D4/DH-2000C4 as models of USB hub (DH short for Double-H presumably). Conmate did show a USB-SCSI converter model CM-660 on their web site at one point. My guess is that was identical to the DH-2000SC. Mention of the Double-H product: http://web.archive.org/web/20010221010141/http://www.doubleh.com.tw/dh-2000sc.htm The only picture I could find is at http://jp.acesuppliers.com/catalog/j64/component/page03.html The casing design looks the same as my ORB USB Smart Cable which has ID 04E6:0002. Anyway, that's enough rambling. Here's the patch. storage: Add quirks for Castlewood and Double-H USB-SCSI converters Add quirks for two SCM-based USB-SCSI converters which were bundled with some Castlewood ORB removable drives.

2014-09-23usb: wusbcore: fix device disconnect on rekey timeoutThomas Pugliese
If three or more wireless devices are connected and two of them disconnect between 1-3 seconds apart, it can cause the HWA to disconnect the remaining devices due to failing to see a DN_Alive message from them. This happens because when the HWA detects that the first device is gone, it will attempt to rekey the remaining devices. If one of the devices is not responding because it has also been disconnected but not yet timed out, the synchronous rekey operation running on the wusbd workqueue can block for up to 5 seconds. This will prevent the KEEPALIVE timer from running and DN_Alive messages from being processed because they are processed by the same workqueue. This patch moves the rekey operation to a separate workqueue since it is the only wusb work item that needs to communicate directly with wireless devices. The rest of the WUSB work items either perform no device IO or communicate directly with the host controller and should not be blocked out by a non-responding wireless device.

2014-09-23usb: wusbcore: skip done segs before completing aborted transferThomas Pugliese
When completing an aborted transfer, skip done segs before calling wa_complete_remaining_xfer_segs to avoid a runtime warning. The warning is harmless in this case but avoiding it prevents false error reports.
