| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since Revision 1.10 was released the n_r3964 module wasn't able to receive any data.

| | * [PATCH] USB: fix bug in handling of highspeed usb HID devicesChristian Krause2005-10-171-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the development of an USB device I found a bug in the handling of Highspeed HID devices in the kernel. What happened? Highspeed HID devices are correctly recognized and enumerated by the kernel. But even if usbhid kernel module is loaded, no HID reports are received by the kernel. The output of the hardware USB analyzer told me that the host doesn't even poll for interrupt IN transfers (even the "interrupt in" USB transfer are polled by the host). After some debugging in hid-core.c I've found the reason. In case of a highspeed device, the endpoint interval is re-calculated in driver/usb/input/hid-core.c: line 1669: /* handle potential highspeed HID correctly */ interval = endpoint->bInterval; if (dev->speed == USB_SPEED_HIGH) interval = 1 << (interval - 1); Basically this calculation is correct (refer to USB 2.0 spec, 9.6.6). This new calculated value of "interval" is used as input for usb_fill_int_urb: line 1685: usb_fill_int_urb(hid->urbin, dev, pipe, hid->inbuf, 0, hid_irq_in, hid, interval); Unfortunately the same calculation as above is done a second time in usb_fill_int_urb in the file include/linux/usb.h: line 933: if (dev->speed == USB_SPEED_HIGH) urb->interval = 1 << (interval - 1); else urb->interval = interval; This means, that if the endpoint descriptor (of a high speed device) specifies e.g. bInterval = 7, the urb->interval gets the value: hid-core.c: interval = 1 << (7-1) = 0x40 = 64 urb->interval = 1 << (interval -1) = 1 << (63) = integer overflow Because of this the value of urb->interval is sometimes negative and is rejected in core/urb.c: line 353: /* too small? */ if (urb->interval <= 0) return -EINVAL; The conclusion is, that the recalculaton of the interval (which is necessary for highspeed) should not be made twice, because this is simply wrong. ;-) Re-calculation in usb_fill_int_urb makes more sense, because it is the most general approach. So it would make sense to remove it from hid-core.c. Because in hid-core.c the interval variable is only used for calling usb_fill_int_urb, it is no problem to remove the highspeed re-calculation in this file.

| | * [PATCH] isp116x-hcd: fix handling of short transfersOlav Kongas2005-10-171-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Increased use of scatter-gather by usb-storage driver after 2.6.13 has exposed a buggy codepath in isp116x-hcd, which was probably never visited before: bug happened only for those urbs, for which URB_SHORT_NOT_OK was set AND short transfer occurred. The fix attached was tested in 2 ways: (a) it fixed failing initialization of a flash drive with an embedded hub; (b) the fix was tested with 'usbtest' against a modified g_zero driver (on top of net2280), which generated short bulk IN transfers of various lengths including multiples and non-multiples of max_packet_length.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the fact that the svideo input will only give input in black/white in some circumstances. Reason is that in the PCI controller driver (zr36067), after setting input, we reset norm, which overwrites the input register with the default.

I didn't know about messy programs like svgatextmode... Couldn't this be integrated in some linux/drivers/video/console/svgacon.c ?... So because of the existence of the svgatextmode program, the kernel is not supposed to touch to CRT_OVERFLOW/SYNC_END/DISP/DISP_END/OFFSET ? Disabling the check in vgacon_resize() might help indeed, but I'm really not sure whether it will work for any chipset: in my patch, CRT registers are set at each console switch, since stty rows/cols apply to consoles separately... The attached solution is to keep the test, but if it fails, we assume that the caller knows what it does (i.e. it is svgatextmode) and then disable any further call to vgacon_doresize. Svgatextmode is usually used to _expand_ the display, not to shrink it. And it is harmless in the case of a too big stty rows/cols: the display will just be cropped. I tested it on my laptop, and it works fine with svgatextmode. A better solution would be that svgatextmode explicitely tells the kernel not to care about video timing, but for this an interface needs be defined and svgatextmode be patched.

The driver really doesn't depend on ISA, it does some ISA stuff in the initialization code, since the driver supports both ISA and PCI cards. So the driver should depend on ISA_DMA_API to build on all systems, and this will not hurt PCI at all.

This adds in efficiency as every packet update makes the /sys/class/firmware/dell_rbu/loading and data files to disappear and reappear again. Thus the user app needs to wait for the files to reappear to dump another packet. This slows down the packet update tremendously in case of large number of packets. I am submitting a new patch for dell_rbu which will change the way we do packet updates; In the new method the user app will create a new single file which has already packetized the rbu image and all the packets are now staged in this file. This driver also creates a new entry in /sys/devices/platform/dell_rbu/packet_size ; the user needs to echo the packet size here before downloading the packet file. The user should do the following: create one single file which has all the packets stacked together. echo the packet size in to /sys/devices/platform/dell_rbu/packet_size. echo 1 > /sys/class/firmware/dell_rbu/loading cat the packetfile > /sys/class/firmware/dell_rbu/data echo 0 > /sys/class/firmware/dell_rbu/loading The driver takes the file which came through /sys/class/firmware/dell_rbu/data and takes chunks of paket_size data from it and place in contiguous memory. This makes packet update process very efficient and fast. As all the packet update happens in one single operation. The user can still read back the downloaded file from /sys/devices/platform/dell_rbu/data.

| | |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Search for a disconnect ccw_device on the ccw bus rather than on the css bus (was a typo in patch I did for the klist conversion). A cast to an embedding ccw_device from an embedded device in a struct subchannel will lead us to oopses.

| | * | [PATCH] Fix signal sending in usbdevio on async URB completionHarald Welte2005-10-101-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a process issues an URB from userspace and (starts to) terminate before the URB comes back, we run into the issue described above. This is because the urb saves a pointer to "current" when it is posted to the device, but there's no guarantee that this pointer is still valid afterwards. In fact, there are three separate issues: 1) the pointer to "current" can become invalid, since the task could be completely gone when the URB completion comes back from the device. 2) Even if the saved task pointer is still pointing to a valid task_struct, task_struct->sighand could have gone meanwhile. 3) Even if the process is perfectly fine, permissions may have changed, and we can no longer send it a signal. So what we do instead, is to save the PID and uid's of the process, and introduce a new kill_proc_info_as_uid() function.
