2006-01-04[PATCH] USB: allow usb drivers to disable dynamic idsGreg Kroah-Hartman
This lets drivers, like the usb-serial ones, disable the ability to add ids from sysfs. The usb-serial drivers are "odd" in that they are really usb-serial bus drivers, not usb bus drivers, so the dynamic id logic will have to go into the usb-serial bus core for those drivers to get that ability. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-01-04[PATCH] USB: add dynamic id functionality to USB coreGreg Kroah-Hartman
Echo the usb vendor and product id to the "new_id" file in the driver's sysfs directory, and then that driver will be able to bind to a device with those ids if it is present. Example: echo 0557 2008 > /sys/bus/usb/drivers/foo_driver/new_id adds the hex values 0557 and 2008 to the device id table for the foo_driver. Note, usb-serial drivers do not currently work with this capability yet. usb-storage also might have some oddities. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2006-01-04[PATCH] USB: central handling for host controllers that were reset during ↵Alan Stern
suspend/resume This patch (as515b) adds a routine to usbcore to simplify handling of host controllers that lost power or were reset during suspend/resume. The new core routine marks all the child devices of the root hub as NOTATTACHED and tells khubd to disconnect the device structures as soon as possible.

2006-01-04[PATCH] USB: dummy_hcd: rename variablesAlan Stern
The recent platform_device update has reintroduced into dummy_hcd.c the dreaded dev->dev syndrome.

2006-01-04[PATCH] USB: file-storage gadget: Add reference count for childrenAlan Stern
This patch (as601) adds a proper reference count to the file-storage gadget's main data structure, to keep track of references held by child devices (LUNs in this case). Before this, the driver would wait for each child to be released before unbinding. While there's nothing really wrong with that (you can't create a hang by doing "rmmod g_file_storage </sys/.../lun0/ro" since the open file will prevent rmmod from running), the code might as well follow the standard procedures. Besides, this shrinks the size of the structure by a few words... :-) Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2006-01-04[PATCH] USB: wakeup flag updates (2/3) uhci-hcdDavid Brownell
This makes UHCI stop using the HCD glue wakeup flags to report whether the controller can wake the system. The existing code was wrong anyway; having a PCI PM capability doesn't imply it reports PME# is supported. I skimmed Intel's ICH7 datasheet and that basically says the wakeup signaling gets routed only through ACPI registers. (On the other hand, many VIA chips provide the PCI PM capabilities...) I think that doing this correctly with UHCI is going to require the ACPI folk to associate the /proc/acpi/wakeup identifiers (and wakeup enable/disable flags) with the relevant /sys/devices/pci*/... devices.

2006-01-04[PATCH] USB: ehci fix driver model wakeup flagsDavid Brownell
On some systems, EHCI seems to be getting IRQs too early during driver setup ... before the root hub is allocated, in particular, making trouble for any code chasing down root hub pointers!

2006-01-04[PATCH] USB: Eagle and ADI 930 usb adsl modem drivermatthieu castet
A driver for USB ADSL modems based on the ADI eagle chipset using the usb_atm infrastructure. The managing part was taken from bsd ueagle driver, other parts were written from scratch. The driver uses the in-kernel firmware loader : - to load a first usb firmware when the modem is in pre-firmware state - to load the dsp firmware that are swapped in host memory. - to load CMV (configuration and management variables) when the modem boot. (We can't use options or sysfs for this as there many possible values. See https://mail.gna.org/public/eagleusb-dev/2005-04/msg00031.html for a description of some) - to load fpga code for 930 chipset. The device had 4 endpoints : * 2 for data (use by usbatm). The incoming endpoint could be iso or bulk. The modem seems buggy and produce lot's of atm errors when using it in bulk mode for speed > 3Mbps, so iso endpoint is need for speed > 3Mbps. At the moment iso endpoint need a patched usbatm library and for this reason is not included in this patch. * One bulk endpoint for uploading dsp firmware * One irq endpoint that notices the driver - if we need to upload a page of the dsp firmware - an ack for read or write CMV and the value (for the read case). If order to make the driver cleaner, we design synchronous (read|write)_cmv : -send a synchronous control message to the modem -wait for an ack or a timeout -return the value if needed. In order to run these synchronous usb messages we need a kernel thread. The driver has been tested with sagem fast 800 modems with different eagle chipset revision and with ADI 930 since April 2005.

2006-01-04[PATCH] USB: EHCI: fix conflation of buf == 0 with len == 0Alan Stern
When the ehci-hcd driver prepares a control URB, it tests for a zero-length data stage by looking at the transfer_dma value instead of the transfer_buffer_length. (In fact it does this even for non-control URBs, which is an additional aspect of the same bug.) However, under certain circumstances it's possible for transfer_dma to be 0 while transfer_buffer_length is non-zero. This can happen when a freshly allocated page (mapped to address 0 and marked Copy-On-Write, but never written to) is used as the source buffer for an OUT transfer. This patch (as598) fixes the problem.

2006-01-04[PATCH] USB: isp116x-hcd: cleanupOlav Kongas
The attached patch makes a cleanup of isp116x-hcd. Most of the volume of the patch comes from 2 sources: moving the code around to get rid of a few function prototypes and reworking register dumping functions/macros. Among other things, switched over from using procfs to debugfs. Cleanup. The following changes were made: - Rework register dumping code so it can be used for dumping to both syslog and debugfs. - Switch from procfs to debugfs.. - Die gracefully on Unrecoverable Error interrupt. - Fix memory leak in isp116x_urb_enqueue(), if HC happens to die in a narrow time window. - Fix a 'sparce' warning (unnecessary cast). - Report Devices Removable for root hub ports by default (was Devices Permanently Attached). - Move bus suspend/resume functions down in code to get rid of a few function prototypes. - A number of one-line cleanups. - Add an entry to MAINTAINERS.

2006-01-02[PATCH] Avoid namespace pollution in <asm/param.h>Dag-Erling Smørgrav
In commit 3D59121003721a8fad11ee72e646fd9d3076b5679c, the x86 and x86-64 <asm/param.h> was changed to include <linux/config.h> for the configurable timer frequency. However, asm/param.h is sometimes used in userland (it is included indirectly from <sys/param.h>), so your commit pollutes the userland namespace with tons of CONFIG_FOO macros. This greatly confuses software packages (such as BusyBox) which use CONFIG_FOO macros themselves to control the inclusion of optional features.

2006-01-02[PATCH] powerpc: more g5 overtemp problem fixBenjamin Herrenschmidt
Some G5s still occasionally experience shutdowns due to overtemp conditions despite the recent fix. After analyzing logs from such machines, it appears that the overtemp code is a bit too quick at shutting the machine down when reaching the critical temperature (tmax + 8) and doesn't leave the fan enough time to actually cool it down. This happens if the temperature of a CPU suddenly rises too high in a very short period of time, or occasionally on boot (that is the CPUs are already overtemp by the time the driver loads). This patches makes the code a bit more relaxed, leaving a few seconds to the fans to do their job before kicking the machine shutown.

2005-12-30[PATCH] Fix false old value return of sysctlYi Yang
For the sysctl syscall, if the user wants to get the old value of a sysctl entry and set a new value for it in the same syscall, the old value is always overwritten by the new value if the sysctl entry is of string type and if the user sets its strategy to sysctl_string. This issue lies in the strategy being run twice if the strategy is set to sysctl_string, the general strategy sysctl_string always returns 0 if success. Such strategy routines as sysctl_jiffies and sysctl_jiffies_ms return 1 because they do read and write for the sysctl entry. The strategy routine sysctl_string return 0 although it actually read and write the sysctl entry. According to my analysis, if a strategy routine do read and write, it should return 1, if it just does some necessary check but not read and write, it should return 0, for example sysctl_intvec.

2005-12-30sysctl: don't overflow the user-supplied buffer with '\0'Linus Torvalds
