2007-08-22USB: fix DoS in pwc USB video driverOliver Neukum
the pwc driver has a disconnect method that waits for user space to close the device. This opens up an opportunity for a DoS attack, blocking the USB subsystem and making khubd's task busy wait in kernel space. This patch shifts freeing resources to close if an opened device is disconnected.

2007-04-27V4L/DVB (5461): Pwc: cisco VT Camera supportJean Tourrilhes
I have a Cisco VT Camera, and it was just collecting dust. I decided to try connecting it to my Linux box at home. Just a disgression about the product. The Cisco VT Camera is a webcam Cisco sold to work with their IP phone hardware and software. It's mostly useless on Windows, as it interfaces only to Cisco software. You can find some for cheap on eBay... Physically, it's just a Logitech Pro 4000. The only difference with the Pro 4000 is the Cisco logo and that it's grey like the Pro 3000. I believe Cisco is now selling the Cisco VT Camera II, which look to be something else... So, assuming that it was a Pro 4000 inside, I created the little patch attached. I'm new to webcam under Linux, but I managed to get an image from it using xawtv, and the image looked all right, so I consider that a success. The imaged seemed a bit small and I could not get the microphone driver loaded, but I assume it's my lack of experience. Note that I did not try any other type_id, but this one works great.

2007-02-21V4L/DVB (5166): Remove obsolete alias defines of CONFIG_* settingsTrent Piepho
The out of tree v4l-dvb build system didn't always override the kernel's configuration settings with v4l-dvb's settings correctly. To work around this, makefiles would define some new macro based on the setting of a config variable. e.g. the pwc Makefile would define CONFIG_PWC_DEBUG if CONFIG_USB_PWC_DEBUG (which is defined via Kconfig) was set. The v4l-dvb build system should now always override correctly, and this is no longer necessary. This patch gets ride of these extra defines and just uses the CONFIG_* settings directly.

2007-02-12[PATCH] mark struct file_operations const 4Arjan van de Ven
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

2006-09-27USB: Dealias -110 code (more complete)Pete Zaitcev
The purpose of this patch is to split off the case when a device does not reply on the lower level (which is reported by HC hardware), and a case when the device accepted the request, but does not reply at upper level. This redefinition allows to diagnose issues easier, without asking the user if the -110 happened "immediately". The usbmon splits such cases already thanks to its timestamp, but it's not always available. I adjusted all drivers which I found affected (by searching for "urb"). Out of tree drivers may suffer a little bit, but I do not expect much breakage. At worst they may print a few messages.

2006-03-25V4L/DVB (3599a): Move drivers/usb/media to drivers/media/videoMauro Carvalho Chehab
Because of historic reasons, there are two separate directories with V4L stuff. Most drivers are located at driver/media/video. However, some code for USB Webcams were inserted under drivers/usb/media. This makes difficult for module authors to know were things should be. Also, makes Kconfig menu confusing for normal users. This patch moves all V4L content under drivers/usb/media to drivers/media/video, and fixes Kconfig/Makefile entries.
