2005-10-10Use the new "kill_proc_info_as_uid()" for USB disconnect tooLinus Torvalds
All the same issues - we can't just save the pointer to the thread, we must save the pid/uid/euid combination. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-10-10[PATCH] Fix signal sending in usbdevio on async URB completionHarald Welte
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.

Addresses some small bugs in the pegasus ethernet-over-USB driver.

2005-09-22[PATCH] USB: ftdi_sio: allow baud rate to be changed without raising RTS and DTRPeter Favrholdt
I'm using a 2 port USB RS232 dongle to connect to a serial-IR cradle for a bar code reader). Detecting the baudrate of the serial-IR involves keeping DTR low while changing baudrate. This works using normal 16550A serial ports as well as the FTDI driver version 1.4.0 (Linux 2.6.8) but stopped working with the change to "ensure RTS and DTR are raised when changing baudrate" introduced in version 1.4.1 (Linux 2.6.9). The attached patch fixes this, so RTS and DTR is only raised when changing baudrate iff the previous baudrate was B0.

2005-09-12[PATCH] USB: storage: Fix messed-up lockingMatthew Dharm
This is patch as550 from Alan Stern. Apparently someone changed the SCSI core so that it no longer holds the host lock when doing a device or bus reset. usb-storage was updated at the time, but the change was done carelessly. Some of the code depends on that lock being held. This patch reintroduces the host lock where needed and tries to clarify the comments explaining why the lock is necessary. It also moves the code that clears the TIMED_OUT and ABORTING bitflags so that it executes as soon as the timed-out command has completed (and while the host lock is held).

2005-09-12[PATCH] USB: OHCI, pxa27x OHCI port power tweaksDavid Brownell
Now that it's in use on other boards, a bug in the original code needs fixing. There is no need for the PXA27x OHCI to set usb power during init, since the hub driver in usbcore handles that. Those platform-specific power control functions are also incorrect, and should therefore be removed. Add a check to clear the OTG pin hold bit until such times OTG is properly implemented.

2005-09-12[PATCH] USB: OHCI relies less on NDP registerDavid Brownell
Some OHCI implementations have differences in the way the NDP register (in roothub_a) reports the number of ports present. This patch allows the platform specific code to optionally supply the number of ports. The driver just reads the value at init (if not supplied) instead of reading it every time its needed (except for an AMD756 bug workaround). It also sets the value correctly for the ARM pxa27x architecture.

2005-09-12[PATCH] USB: EHCI port tweaksDavid Brownell
One change may improve some S1 or S3 resume cases, and the other seems mostly to explain some strange state "lsusb" would show. Two fixes: - On resume, don't think about resuming any unpowered port, or resetting any port with OWNER set to the OHCI/UHCI companion. This will make some S1 and S3 resume scenarios work better. - PORT_CSC was not being cleared correctly in ehci_hub_status_data. This was visible at least through current versions of "lsusb", and might have caused some other hub related strangeness. The fix addresses all three write-to-clear bits, using the same approach that UHCI happens to use: a mask of bits that are cleared in most writes to that port status register. Original patch seems to have been from from William.Morrow@amd.com and this version (from David) finishes the write-to-clear changes.

2005-09-12[PATCH] USB: add apple usb touchpad driverStelian Pop
This is a driver for the USB touchpad which can be found on post-February 2005 Apple PowerBooks. This driver is derived from Johannes Berg's appletrackpad driver [1], but it has been improved in some areas: * appletouch is a full kernel driver, no userspace program is necessary * appletouch can be interfaced with the synaptics X11 driver[2], in order to have touchpad acceleration, scrolling, two/three finger tap, etc. This driver has been tested by the readers of the 'debian-powerpc' mailing list for a few weeks now and I believe it is now ready for inclusion into the mainline kernel. Credits go to Johannes Berg for reverse-engineering the touchpad protocol, Frank Arnold for further improvements, and Alex Harper for some additional information about the inner workings of the touchpad sensors.

2005-09-12[PATCH] USB: sisusb[vga] updateThomas Winischhofer
here is a new and extended version of the sisusbvga (previously: sisusb) driver. The patch is against 2.6.13 and updates the driver to version 0.0.8. Additions include complete VGA/EGA text console support and a build-in display mode infrastructure for userland applications that don't know about the graphics internals. Fixes include some BE/LE issues and a get/put_dev bug in the previous version. Other changes include a change of the module name from "sisusb" to "sisusbvga". The previous one was too generic IMHO. Please note that the patch also affects the Makefile in drivers/video/console as the driver requires the VGA 8x16 font in case the text console part is selected. Heavily tested, as usual. Please apply. One thing though: I already prepared for removal of the "mode" field and the changed "name" field in the usb_class_driver structure. This will perhaps need some refinement depending on whether you/Linus merge the respective core changes before or after 2.6.14.
