* Convert files to UTF-8 and some cleanupsJan Engelhardt2007-10-19
| | | | | | | | | | | | | | | | | | * Convert files to UTF-8. * Also correct some people's names (one example is Eißfeldt, which was found in a source file. Given that the author used an ß at all in a source file indicates that the real name has in fact a 'ß' and not an 'ss', which is commonly used as a substitute for 'ß' when limited to 7bit.) * Correct town names (Goettingen -> Göttingen) * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313) Signed-off-by: Jan Engelhardt <jengelh@gmx.de> Signed-off-by: Adrian Bunk <bunk@kernel.org>

* vt/vgacon: Check if screen resize request comes from userspaceAntonino A. Daplas2007-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | Various console drivers are able to resize the screen via the con_resize() hook. This hook is also visible in userspace via the TIOCWINSZ, VT_RESIZE and VT_RESIZEX ioctl's. One particular utility, SVGATextMode, expects that con_resize() of the VGA console will always return success even if the resulting screen is not compatible with the hardware. However, this particular behavior of the VGA console, as reported in Kernel Bugzilla Bug 7513, can cause undefined behavior if the user starts with a console size larger than 80x25. To work around this problem, add an extra parameter to con_resize(). This parameter is ignored by drivers except for vgacon. If this parameter is non-zero, then the resize request came from a VT_RESIZE or VT_RESIZEX ioctl and vgacon will always return success. If this parameter is zero, vgacon will return -EINVAL if the requested size is not compatible with the hardware. The latter is the more correct behavior. With this change, SVGATextMode should still work correctly while in-kernel and stty resize calls can expect correct behavior from vgacon.

* USB: prevent char device open/deregister raceAlan Stern2007-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as908) adds central protection in usbcore for the prototypical race between opening and unregistering a char device. The spinlock used to protect the minor-numbers array is replaced with an rwsem, which can remain locked across a call to a driver's open() method. This guarantees that open() and deregister() will be mutually exclusive. The private locks currently used in several individual drivers for this purpose are no longer necessary, and the patch removes them. The following USB drivers are affected: usblcd, idmouse, auerswald, legousbtower, sisusbvga/sisusb, ldusb, adutux, iowarrior, and usb-skeleton. As a side effect of this change, usb_deregister_dev() must not be called while holding a lock that is acquired by open(). Unfortunately a number of drivers do this, but luckily the solution is simple: call usb_deregister_dev() before acquiring the lock. In addition to these changes (and their consequent code simplifications), the patch fixes a use-after-free bug in adutux and a race between open() and release() in iowarrior.

* potential compiler error, irqfunc caller sites updateYoann Padioleau2007-07-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In 7d12e780e003f93433d49ce78cfedf4b4c52adc5 David Howells performed this evolution: "IRQ: Maintain regs pointer globally rather than passing to IRQ handlers" He correctly updated many of the function definitions that were using this extra regs pointer parameter but forgot to update some caller sites of those functions. The reason the modifications was not properly done on all drivers is that some drivers were rarely compiled because they are for AMIGA, or that some code sites were inside #ifdefs where the option is not set or inside #if 0.

| | | | | | | | | | | | | | | | | | | | The driver uses usb_control_msg() for exchanging data with the device. When the driver lived freeley _outside_ the kernel tree (pre 2.6.21) the timeouts for these calls where set to 5*HZ for reading, 1HZ for writing. (These timeouts seemed to work fine for all users of the driver, at least nobody complained in the last 2 years. The current code (2.6.21-rc5) removed the 'HZ' from the timeouts and left the driver with 5 jiffies for reading and 1 jiffy for writing. My new machine is fast, but not that fast.
