2010-09-23returning here can cause the usb task thread to go to sleep forever,Jacob Meuser
becaue it skips a wakeup() later on. this is the only error condition that returns before the wakeup. not sure why this particular case is handled differently, and not certain what the error code should be, but this is better than breaking all of usb because of a problem on one port. dicussed with deraadt
2010-09-23add two members to struct usb_taskJacob Meuser
* usbd_device_handle dev - the device responsible for the task. use this to not run the task if the device's hub is dying. * int running - a flag to be set when the task is running. add usb_rem_wait_task(), a wrapper for usb_rem_task() that waits for the task to complete if the task is already running. s/usb_rem_task/usb_rem_wait_task/ in usb_detach(). probably most drivers using usb_tasks should do this as well. although device attach/detach is serialized in normal cases, in the special case where the usb bus is hotpluggable (like cardbus/pcmcia), devices are not detached in the task thread.
2010-09-23add a 'dying' flag to struct usbd_bus. use this to signify the busJacob Meuser
is dying, instead of setting a flag in struct usb_softc. as usbd_device_handle has a pointer to the usbd_bus it's attached to, usb devices, and functions they run or functions run on their behalf, can now easily check if their bus is dying. use this to stop usbd_do_request* from running and the usb task thread from adding new tasks when a device's bus is dying.
2010-09-23instead of waiting the full power-up-to-power-steady time for rootJacob Meuser
hubs before their first port explore, check how long it's actually been since power up and only wait as necessary. saves a little time on boot, especially now that explore tasks are serialized. ok yuo@
2010-09-23instead of running usb_explore() from individual kthreads for eachJacob Meuser
USB bus, make usb_explore() a usb_task. reduces races during normal USB device detach, since now usb_tasks and detach happen in the same process. ok yuo@, matthew@ helped with the task thread loop

2010-09-21The size of sc_status[] (the buffer for USB hub's interrupt pipe) will besasano
determined by bNbrPorts in hub descriptor. USB hub sends status packet to host, it contains status bits for each port and hub itself. So, the packet size is ceil((port + 1) / 8) bytes. If host requests smaller than that size, the hub behavior is undefined. Some hub (Intel's RMH for example) sends whole status every time, it makes babble of USB. This is the reason that uhub_intr() of old code was suffered from USBD_IOERROR, Okay deraadt@ and yuo@.

fixes problems seen with Linksys USB300M.
2010-09-21umass is set up to only handle one command on the bus at any pointDavid Gwynne
in time, which is a problem if your umass device has multiple luns on it. if multiple commands are issued at the same time then they step on some shared state, which in turn causes some interesting panics. this diff introduces an iopool in umass so only one command can be "allocated" and scheduled at a time. found, reproduced and investigated by krw@ fix verified by krw@ ok matthew@ krw@

DVACT_SUSPEND, therefore DVACT_QUIECE can do standard sleeping operations to get ready. Discussed quite a while back with kettenis and jakemsr, oga suddenly needed it as well and wrote half of it, so it was time to finish it. proofread by miod.

PWR_{SUSPEND,RESUME} so that they match the values of DAVCT_{SUSPEND,RESUME} so that we can eventually (many more steps...) kill the powerhook garbage and use the activate mechanism. no objections

2010-08-01Be more generous when parsing the report descriptor:Miod Vallat
- parts of the report descriptor not in a format we expect are now ignored, instead of preventing attachment (e.g. hypothetical multi-bit modifiers). - modifiers beyond MAXMOD are ignored. - keycode arrays larger than MAXKEYCODE are clamped to MAXKEYCODE instead of being rejected. - multiple keycode arrays are ignored. This should allow rogue keyboards to attach and be usable up to a certain extent. Adapted from a diff sent by Loganaden Velvindron (first name at gmail), who has a keyboard which keycode array is larger than MAXKEYCODE (but, like most if not all USB keyboards out there, can only report up to three simultaneous keypresses anyway).

function is not. This change #if 0's urndis_watchdog() and some functions that are only called from here. At some point we probably want to use the watchdog functionality but the current code is completely untested so disable it entirely rather than enabling it this close to release.
