+
+Authorizing (or not) your USB devices to connect to the system
+
+(C) 2007 Inaky Perez-Gonzalez <inaky@linux.intel.com> Intel Corporation
+
+This feature allows you to control if a USB device can be used (or
+not) in a system. This feature will allow you to implement a lock-down
+of USB devices, fully controlled by user space.
+
+As of now, when a USB device is connected it is configured and
+it's interfaces inmediately made available to the users. With this
+modification, only if root authorizes the device to be configured will
+then it be possible to use it.
+
+Usage:
+
+Authorize a device to connect:
+
+$ echo 1 > /sys/usb/devices/DEVICE/authorized
+
+Deauthorize a device:
+
+$ echo 0 > /sys/usb/devices/DEVICE/authorized
+
+Set new devices connected to hostX to be deauthorized by default (ie:
+lock down):
+
+$ echo 0 > /sys/bus/devices/usbX/authorized_default
+
+Remove the lock down:
+
+$ echo 1 > /sys/bus/devices/usbX/authorized_default
+
+By default, Wired USB devices are authorized by default to
+connect. Wireless USB hosts deauthorize by default all new connected
+devices (this is so because we need to do an authentication phase
+before authorizing).
+
+
+Example system lockdown (lame)
+-----------------------
+
+Imagine you want to implement a lockdown so only devices of type XYZ
+can be connected (for example, it is a kiosk machine with a visible
+USB port):
+
+boot up
+rc.local ->
+
+ for host in /sys/bus/devices/usb*
+ do
+ echo 0 > $host/authorized_default
+ done
+
+Hookup an script to udev, for new USB devices
+
+ if device_is_my_type $DEV
+ then
+ echo 1 > $device_path/authorized
+ done
+
+
+Now, device_is_my_type() is where the juice for a lockdown is. Just
+checking if the class, type and protocol match something is the worse
+security verification you can make (or the best, for someone willing
+to break it). If you need something secure, use crypto and Certificate
+Authentication or stuff like that. Something simple for an storage key
+could be:
+
+function device_is_my_type()
+{
+ echo 1 > authorized # temporarily authorize it
+ # FIXME: make sure none can mount it
+ mount DEVICENODE /mntpoint
+ sum=$(md5sum /mntpoint/.signature)
+ if [ $sum = $(cat /etc/lockdown/keysum) ]
+ then
+ echo "We are good, connected"
+ umount /mntpoint
+ # Other stuff so others can use it
+ else
+ echo 0 > authorized
+ fi
+}
+
+
+Of course, this is lame, you'd want to do a real certificate
+verification stuff with PKI, so you don't depend on a shared secret,
+etc, but you get the idea. Anybody with access to a device gadget kit
+can fake descriptors and device info. Don't trust that. You are
+welcome.

+ Power Management for USB
+
+ Alan Stern <stern@rowland.harvard.edu>
+
+ October 5, 2007
+
+
+
+ What is Power Management?
+ -------------------------
+
+Power Management (PM) is the practice of saving energy by suspending
+parts of a computer system when they aren't being used. While a
+component is "suspended" it is in a nonfunctional low-power state; it
+might even be turned off completely. A suspended component can be
+"resumed" (returned to a functional full-power state) when the kernel
+needs to use it. (There also are forms of PM in which components are
+placed in a less functional but still usable state instead of being
+suspended; an example would be reducing the CPU's clock rate. This
+document will not discuss those other forms.)
+
+When the parts being suspended include the CPU and most of the rest of
+the system, we speak of it as a "system suspend". When a particular
+device is turned off while the system as a whole remains running, we
+call it a "dynamic suspend" (also known as a "runtime suspend" or
+"selective suspend"). This document concentrates mostly on how
+dynamic PM is implemented in the USB subsystem, although system PM is
+covered to some extent (see Documentation/power/*.txt for more
+information about system PM).
+
+Note: Dynamic PM support for USB is present only if the kernel was
+built with CONFIG_USB_SUSPEND enabled. System PM support is present
+only if the kernel was built with CONFIG_SUSPEND or CONFIG_HIBERNATION
+enabled.
+
+
+ What is Remote Wakeup?
+ ----------------------
+
+When a device has been suspended, it generally doesn't resume until
+the computer tells it to. Likewise, if the entire computer has been
+suspended, it generally doesn't resume until the user tells it to, say
+by pressing a power button or opening the cover.
+
+However some devices have the capability of resuming by themselves, or
+asking the kernel to resume them, or even telling the entire computer
+to resume. This capability goes by several names such as "Wake On
+LAN"; we will refer to it generically as "remote wakeup". When a
+device is enabled for remote wakeup and it is suspended, it may resume
+itself (or send a request to be resumed) in response to some external
+event. Examples include a suspended keyboard resuming when a key is
+pressed, or a suspended USB hub resuming when a device is plugged in.
+
+
+ When is a USB device idle?
+ --------------------------
+
+A device is idle whenever the kernel thinks it's not busy doing
+anything important and thus is a candidate for being suspended. The
+exact definition depends on the device's driver; drivers are allowed
+to declare that a device isn't idle even when there's no actual
+communication taking place. (For example, a hub isn't considered idle
+unless all the devices plugged into that hub are already suspended.)
+In addition, a device isn't considered idle so long as a program keeps
+its usbfs file open, whether or not any I/O is going on.
+
+If a USB device has no driver, its usbfs file isn't open, and it isn't
+being accessed through sysfs, then it definitely is idle.
+
+
+ Forms of dynamic PM
+ -------------------
+
+Dynamic suspends can occur in two ways: manual and automatic.
+"Manual" means that the user has told the kernel to suspend a device,
+whereas "automatic" means that the kernel has decided all by itself to
+suspend a device. Automatic suspend is called "autosuspend" for
+short. In general, a device won't be autosuspended unless it has been
+idle for some minimum period of time, the so-called idle-delay time.
+
+Of course, nothing the kernel does on its own initiative should
+prevent the computer or its devices from working properly. If a
+device has been autosuspended and a program tries to use it, the
+kernel will automatically resume the device (autoresume). For the
+same reason, an autosuspended device will usually have remote wakeup
+enabled, if the device supports remote wakeup.
+
+It is worth mentioning that many USB drivers don't support
+autosuspend. In fact, at the time of this writing (Linux 2.6.23) the
+only drivers which do support it are the hub driver, kaweth, asix,
+usblp, usblcd, and usb-skeleton (which doesn't count). If a
+non-supporting driver is bound to a device, the device won't be
+autosuspended. In effect, the kernel pretends the device is never
+idle.
+
+We can categorize power management events in two broad classes:
+external and internal. External events are those triggered by some
+agent outside the USB stack: system suspend/resume (triggered by
+userspace), manual dynamic suspend/resume (also triggered by
+userspace), and remote wakeup (triggered by the device). Internal
+events are those triggered within the USB stack: autosuspend and
+autoresume.
+
+
+ The user interface for dynamic PM
+ ---------------------------------
+
+The user interface for controlling dynamic PM is located in the power/
+subdirectory of each USB device's sysfs directory, that is, in
+/sys/bus/usb/devices/.../power/ where "..." is the device's ID. The
+relevant attribute files are: wakeup, level, and autosuspend.
+
+ power/wakeup
+
+ This file is empty if the device does not support
+ remote wakeup. Otherwise the file contains either the
+ word "enabled" or the word "disabled", and you can
+ write those words to the file. The setting determines
+ whether or not remote wakeup will be enabled when the
+ device is next suspended. (If the setting is changed
+ while the device is suspended, the change won't take
+ effect until the following suspend.)
+
+ power/level
+
+ This file contains one of three words: "on", "auto",
+ or "suspend". You can write those words to the file
+ to change the device's setting.
+
+ "on" means that the device should be resumed and
+ autosuspend is not allowed. (Of course, system
+ suspends are still allowed.)
+
+ "auto" is the normal state in which the kernel is
+ allowed to autosuspend and autoresume the device.
+
+ "suspend" means that the device should remain
+ suspended, and autoresume is not allowed. (But remote
+ wakeup may still be allowed, since it is controlled
+ separately by the power/wakeup attribute.)
+
+ power/autosuspend
+
+ This file contains an integer value, which is the
+ number of seconds the device should remain idle before
+ the kernel will autosuspend it (the idle-delay time).
+ The default is 2. 0 means to autosuspend as soon as
+ the device becomes idle, and -1 means never to
+ autosuspend. You can write a number to the file to
+ change the autosuspend idle-delay time.
+
+Writing "-1" to power/autosuspend and writing "on" to power/level do
+essentially the same thing -- they both prevent the device from being
+autosuspended. Yes, this is a redundancy in the API.
+
+(In 2.6.21 writing "0" to power/autosuspend would prevent the device
+from being autosuspended; the behavior was changed in 2.6.22. The
+power/autosuspend attribute did not exist prior to 2.6.21, and the
+power/level attribute did not exist prior to 2.6.22.)
+
+
+ Changing the default idle-delay time
+ ------------------------------------
+
+The default autosuspend idle-delay time is controlled by a module
+parameter in usbcore. You can specify the value when usbcore is
+loaded. For example, to set it to 5 seconds instead of 2 you would
+do:
+
+ modprobe usbcore autosuspend=5
+
+Equivalently, you could add to /etc/modprobe.conf a line saying:
+
+ options usbcore autosuspend=5
+
+Some distributions load the usbcore module very early during the boot
+process, by means of a program or script running from an initramfs
+image. To alter the parameter value you would have to rebuild that
+image.
+
+If usbcore is compiled into the kernel rather than built as a loadable
+module, you can add
+
+ usbcore.autosuspend=5
+
+to the kernel's boot command line.
+
+Finally, the parameter value can be changed while the system is
+running. If you do:
+
+ echo 5 >/sys/module/usbcore/parameters/autosuspend
+
+then each new USB device will have its autosuspend idle-delay
+initialized to 5. (The idle-delay values for already existing devices
+will not be affected.)
+
+Setting the initial default idle-delay to -1 will prevent any
+autosuspend of any USB device. This is a simple alternative to
+disabling CONFIG_USB_SUSPEND and rebuilding the kernel, and it has the
+added benefit of allowing you to enable autosuspend for selected
+devices.
+
+
+ Warnings
+ --------
+
+The USB specification states that all USB devices must support power
+management. Nevertheless, the sad fact is that many devices do not
+support it very well. You can suspend them all right, but when you
+try to resume them they disconnect themselves from the USB bus or
+they stop working entirely. This seems to be especially prevalent
+among printers and scanners, but plenty of other types of device have
+the same deficiency.
+
+For this reason, by default the kernel disables autosuspend (the
+power/level attribute is initialized to "on") for all devices other
+than hubs. Hubs, at least, appear to be reasonably well-behaved in
+this regard.
+
+(In 2.6.21 and 2.6.22 this wasn't the case. Autosuspend was enabled
+by default for almost all USB devices. A number of people experienced
+problems as a result.)
+
+This means that non-hub devices won't be autosuspended unless the user
+or a program explicitly enables it. As of this writing there aren't
+any widespread programs which will do this; we hope that in the near
+future device managers such as HAL will take on this added
+responsibility. In the meantime you can always carry out the
+necessary operations by hand or add them to a udev script. You can
+also change the idle-delay time; 2 seconds is not the best choice for
+every device.
+
+Sometimes it turns out that even when a device does work okay with
+autosuspend there are still problems. For example, there are
+experimental patches adding autosuspend support to the usbhid driver,
+which manages keyboards and mice, among other things. Tests with a
+number of keyboards showed that typing on a suspended keyboard, while
+causing the keyboard to do a remote wakeup all right, would
+nonetheless frequently result in lost keystrokes. Tests with mice
+showed that some of them would issue a remote-wakeup request in
+response to button presses but not to motion, and some in response to
+neither.
+
+The kernel will not prevent you from enabling autosuspend on devices
+that can't handle it. It is even possible in theory to damage a
+device by suspending it at the wrong time -- for example, suspending a
+USB hard disk might cause it to spin down without parking the heads.
+(Highly unlikely, but possible.) Take care.
+
+
+ The driver interface for Power Management
+ -----------------------------------------
+
+The requirements for a USB driver to support external power management
+are pretty modest; the driver need only define
+
+ .suspend
+ .resume
+ .reset_resume
+
+methods in its usb_driver structure, and the reset_resume method is
+optional. The methods' jobs are quite simple:
+
+ The suspend method is called to warn the driver that the
+ device is going to be suspended. If the driver returns a
+ negative error code, the suspend will be aborted. Normally
+ the driver will return 0, in which case it must cancel all
+ outstanding URBs (usb_kill_urb()) and not submit any more.
+
+ The resume method is called to tell the driver that the
+ device has been resumed and the driver can return to normal
+ operation. URBs may once more be submitted.
+
+ The reset_resume method is called to tell the driver that
+ the device has been resumed and it also has been reset.
+ The driver should redo any necessary device initialization,
+ since the device has probably lost most or all of its state
+ (although the interfaces will be in the same altsettings as
+ before the suspend).
+
+The reset_resume method is used by the USB Persist facility (see
+Documentation/usb/persist.txt) and it can also be used under certain
+circumstances when CONFIG_USB_PERSIST is not enabled. Currently, if a
+device is reset during a resume and the driver does not have a
+reset_resume method, the driver won't receive any notification about
+the resume. Later kernels will call the driver's disconnect method;
+2.6.23 doesn't do this.
+
+USB drivers are bound to interfaces, so their suspend and resume
+methods get called when the interfaces are suspended or resumed. In
+principle one might want to suspend some interfaces on a device (i.e.,
+force the drivers for those interface to stop all activity) without
+suspending the other interfaces. The USB core doesn't allow this; all
+interfaces are suspended when the device itself is suspended and all
+interfaces are resumed when the device is resumed. It isn't possible
+to suspend or resume some but not all of a device's interfaces. The
+closest you can come is to unbind the interfaces' drivers.
+
+
+ The driver interface for autosuspend and autoresume
+ ---------------------------------------------------
+
+To support autosuspend and autoresume, a driver should implement all
+three of the methods listed above. In addition, a driver indicates
+that it supports autosuspend by setting the .supports_autosuspend flag
+in its usb_driver structure. It is then responsible for informing the
+USB core whenever one of its interfaces becomes busy or idle. The
+driver does so by calling these three functions:
+
+ int usb_autopm_get_interface(struct usb_interface *intf);
+ void usb_autopm_put_interface(struct usb_interface *intf);
+ int usb_autopm_set_interface(struct usb_interface *intf);
+
+The functions work by maintaining a counter in the usb_interface
+structure. When intf->pm_usage_count is > 0 then the interface is
+deemed to be busy, and the kernel will not autosuspend the interface's
+device. When intf->pm_usage_count is <= 0 then the interface is
+considered to be idle, and the kernel may autosuspend the device.
+
+(There is a similar pm_usage_count field in struct usb_device,
+associated with the device itself rather than any of its interfaces.
+This field is used only by the USB core.)
+
+The driver owns intf->pm_usage_count; it can modify the value however
+and whenever it likes. A nice aspect of the usb_autopm_* routines is
+that the changes they make are protected by the usb_device structure's
+PM mutex (udev->pm_mutex); however drivers may change pm_usage_count
+without holding the mutex.
+
+ usb_autopm_get_interface() increments pm_usage_count and
+ attempts an autoresume if the new value is > 0 and the
+ device is suspended.
+
+ usb_autopm_put_interface() decrements pm_usage_count and
+ attempts an autosuspend if the new value is <= 0 and the
+ device isn't suspended.
+
+ usb_autopm_set_interface() leaves pm_usage_count alone.
+ It attempts an autoresume if the value is > 0 and the device
+ is suspended, and it attempts an autosuspend if the value is
+ <= 0 and the device isn't suspended.
+
+There also are a couple of utility routines drivers can use:
+
+ usb_autopm_enable() sets pm_usage_cnt to 1 and then calls
+ usb_autopm_set_interface(), which will attempt an autoresume.
+
+ usb_autopm_disable() sets pm_usage_cnt to 0 and then calls
+ usb_autopm_set_interface(), which will attempt an autosuspend.
+
+The conventional usage pattern is that a driver calls
+usb_autopm_get_interface() in its open routine and
+usb_autopm_put_interface() in its close or release routine. But
+other patterns are possible.
+
+The autosuspend attempts mentioned above will often fail for one
+reason or another. For example, the power/level attribute might be
+set to "on", or another interface in the same device might not be
+idle. This is perfectly normal. If the reason for failure was that
+the device hasn't been idle for long enough, a delayed workqueue
+routine is automatically set up to carry out the operation when the
+autosuspend idle-delay has expired.
+
+Autoresume attempts also can fail. This will happen if power/level is
+set to "suspend" or if the device doesn't manage to resume properly.
+Unlike autosuspend, there's no delay for an autoresume.
+
+
+ Other parts of the driver interface
+ -----------------------------------
+
+Sometimes a driver needs to make sure that remote wakeup is enabled
+during autosuspend. For example, there's not much point
+autosuspending a keyboard if the user can't cause the keyboard to do a
+remote wakeup by typing on it. If the driver sets
+intf->needs_remote_wakeup to 1, the kernel won't autosuspend the
+device if remote wakeup isn't available or has been disabled through
+the power/wakeup attribute. (If the device is already autosuspended,
+though, setting this flag won't cause the kernel to autoresume it.
+Normally a driver would set this flag in its probe method, at which
+time the device is guaranteed not to be autosuspended.)
+
+The usb_autopm_* routines have to run in a sleepable process context;
+they must not be called from an interrupt handler or while holding a
+spinlock. In fact, the entire autosuspend mechanism is not well geared
+toward interrupt-driven operation. However there is one thing a
+driver can do in an interrupt handler:
+
+ usb_mark_last_busy(struct usb_device *udev);
+
+This sets udev->last_busy to the current time. udev->last_busy is the
+field used for idle-delay calculations; updating it will cause any
+pending autosuspend to be moved back. The usb_autopm_* routines will
+also set the last_busy field to the current time.
+
+Calling urb_mark_last_busy() from within an URB completion handler is
+subject to races: The kernel may have just finished deciding the
+device has been idle for long enough but not yet gotten around to
+calling the driver's suspend method. The driver would have to be
+responsible for synchronizing its suspend method with its URB
+completion handler and causing the autosuspend to fail with -EBUSY if
+an URB had completed too recently.
+
+External suspend calls should never be allowed to fail in this way,
+only autosuspend calls. The driver can tell them apart by checking
+udev->auto_pm; this flag will be set to 1 for internal PM events
+(autosuspend or autoresume) and 0 for external PM events.
+
+Many of the ingredients in the autosuspend framework are oriented
+towards interfaces: The usb_interface structure contains the
+pm_usage_cnt field, and the usb_autopm_* routines take an interface
+pointer as their argument. But somewhat confusingly, a few of the
+pieces (usb_mark_last_busy() and udev->auto_pm) use the usb_device
+structure instead. Drivers need to keep this straight; they can call
+interface_to_usbdev() to find the device structure for a given
+interface.
+
+
+ Locking requirements
+ --------------------
+
+All three suspend/resume methods are always called while holding the
+usb_device's PM mutex. For external events -- but not necessarily for
+autosuspend or autoresume -- the device semaphore (udev->dev.sem) will
+also be held. This implies that external suspend/resume events are
+mutually exclusive with calls to probe, disconnect, pre_reset, and
+post_reset; the USB core guarantees that this is true of internal
+suspend/resume events as well.
+
+If a driver wants to block all suspend/resume calls during some
+critical section, it can simply acquire udev->pm_mutex.
+Alternatively, if the critical section might call some of the
+usb_autopm_* routines, the driver can avoid deadlock by doing:
+
+ down(&udev->dev.sem);
+ rc = usb_autopm_get_interface(intf);
+
+and at the end of the critical section:
+
+ if (!rc)
+ usb_autopm_put_interface(intf);
+ up(&udev->dev.sem);
+
+Holding the device semaphore will block all external PM calls, and the
+usb_autopm_get_interface() will prevent any internal PM calls, even if
+it fails. (Exercise: Why?)
+
+The rules for locking order are:
+
+ Never acquire any device semaphore while holding any PM mutex.
+
+ Never acquire udev->pm_mutex while holding the PM mutex for
+ a device that isn't a descendant of udev.
+
+In other words, PM mutexes should only be acquired going up the device
+tree, and they should be acquired only after locking all the device
+semaphores you need to hold. These rules don't matter to drivers very
+much; they usually affect just the USB core.
+
+Still, drivers do need to be careful. For example, many drivers use a
+private mutex to synchronize their normal I/O activities with their
+disconnect method. Now if the driver supports autosuspend then it
+must call usb_autopm_put_interface() from somewhere -- maybe from its
+close method. It should make the call while holding the private mutex,
+since a driver shouldn't call any of the usb_autopm_* functions for an
+interface from which it has been unbound.
+
+But the usb_autpm_* routines always acquire the device's PM mutex, and
+consequently the locking order has to be: private mutex first, PM
+mutex second. Since the suspend method is always called with the PM
+mutex held, it mustn't try to acquire the private mutex. It has to
+synchronize with the driver's I/O activities in some other way.
+
+
+ Interaction between dynamic PM and system PM
+ --------------------------------------------
+
+Dynamic power management and system power management can interact in
+a couple of ways.
+
+Firstly, a device may already be manually suspended or autosuspended
+when a system suspend occurs. Since system suspends are supposed to
+be as transparent as possible, the device should remain suspended
+following the system resume. The 2.6.23 kernel obeys this principle
+for manually suspended devices but not for autosuspended devices; they
+do get resumed when the system wakes up. (Presumably they will be
+autosuspended again after their idle-delay time expires.) In later
+kernels this behavior will be fixed.
+
+(There is an exception. If a device would undergo a reset-resume
+instead of a normal resume, and the device is enabled for remote
+wakeup, then the reset-resume takes place even if the device was
+already suspended when the system suspend began. The justification is
+that a reset-resume is a kind of remote-wakeup event. Or to put it
+another way, a device which needs a reset won't be able to generate
+normal remote-wakeup signals, so it ought to be resumed immediately.)
+
+Secondly, a dynamic power-management event may occur as a system
+suspend is underway. The window for this is short, since system
+suspends don't take long (a few seconds usually), but it can happen.
+For example, a suspended device may send a remote-wakeup signal while
+the system is suspending. The remote wakeup may succeed, which would
+cause the system suspend to abort. If the remote wakeup doesn't
+succeed, it may still remain active and thus cause the system to
+resume as soon as the system suspend is complete. Or the remote
+wakeup may fail and get lost. Which outcome occurs depends on timing
+and on the hardware and firmware design.
+
+More interestingly, a device might undergo a manual resume or
+autoresume during system suspend. With current kernels this shouldn't
+happen, because manual resumes must be initiated by userspace and
+autoresumes happen in response to I/O requests, but all user processes
+and I/O should be quiescent during a system suspend -- thanks to the
+freezer. However there are plans to do away with the freezer, which
+would mean these things would become possible. If and when this comes
+about, the USB core will carefully arrange matters so that either type
+of resume will block until the entire system has resumed.

Generic Serial driver
If your device is not one of the above listed devices, compatible with
Verify that bus sockets are present.
# ls /sys/kernel/debug/usbmon
-1s 1t 1u 2s 2t 2u 3s 3t 3u 4s 4t 4u
+0s 0t 0u 1s 1t 1u 2s 2t 2u 3s 3t 3u 4s 4t 4u
#
+Now you can choose to either use the sockets numbered '0' (to capture packets on
+all buses), and skip to step #3, or find the bus used by your device with step #2.
+
2. Find which bus connects to the desired device
Run "cat /proc/bus/usb/devices", and find the T-line which corresponds to
# cat /sys/kernel/debug/usbmon/3u > /tmp/1.mon.out
+to listen on a single bus, otherwise, to listen on all buses, type:
+
+# cat /sys/kernel/debug/usbmon/0u > /tmp/1.mon.out
+
This process will be reading until killed. Naturally, the output can be
redirected to a desirable location. This is preferred, because it is going
to be quite long.
