由 Alan Stern 提交于
29 July 2005, Cambridge, MA: This afternoon Alan Stern submitted a patch to remove the URB_ASYNC_UNLINK flag from the Linux kernel. Mr. Stern explained, "This flag is a relic from an earlier, less-well-designed system. For over a year it hasn't been used for anything other than printing warning messages." An anonymous spokesman for the Linux kernel development community commented, "This is exactly the sort of thing we see happening all the time. As the kernel evolves, support for old techniques and old code can be jettisoned and replaced by newer, better approaches. Proprietary operating systems do not have the freedom or flexibility to change so quickly." Mr. Stern, a staff member at Harvard University's Rowland Institute who works on Linux only as a hobby, noted that the patch (labelled as548) did not update two files, keyspan.c and option.c, in the USB drivers' "serial" subdirectory. "Those files need more extensive changes," he remarked. "They examine the status field of several URBs at times when they're not supposed to. That will need to be fixed before the URB_ASYNC_UNLINK flag is removed." Greg Kroah-Hartman, the kernel maintainer responsible for overseeing all of Linux's USB drivers, did not respond to our inquiries or return our calls. His only comment was "Applied, thanks."

This patch started life as as479b, and has been rediffed. Please note the order of submission of this latest patch series -- even tho this has an older original number, it is the last patch I'll be sending today. This patch changes the reported SCSI revision level to 2 for all disk-type devices. This is needed in a few cases because the device reports a level of 3 or higher but then crashes when given a REPORT LUNS command (for which support is supposed to be mandatory at those levels). This shouldn't harm us, since it only matters for sparse LUNs and we have separate ways of coping with that.

This patch is originally from Nick Sillik, and has been rediffed against the latest tree. This patch adds usability to the OneTouch Button on Maxtor External USB Hard Drives. Using an unusual device entry it declares an extra init function which claims the interrupt endpoint associated with this button. The button is connected to the input system.

This patch started life as as534, and has been re-diffed against the latest tree. usb-storage has a small loophole, a window between the time queuecommand accepts a new command and the time the control thread starts to execute it. If disconnect is called during that window, the driver won't cancel the pending command -- we've been relying on the SCSI core to cancel it for us during host removal. But it's better for usb-storage to cancel it; this avoids races and reduces reliance on the SCSI core. Fortunately cancelling these commands is easy to do; the key is to do it _before_ calling scsi_remove_host.

This patch started life as as533, and has been re-diffed against the current tree. Disconnect processing in usb-storage naturally divides into two parts: one to quiesce the driver (make sure no commands are executing or queued) and remove the host, and the other to deallocate all the USB and non-USB resources. This patch creates two subroutines to handle those two parts. Mostly it's just code movement, but there is one significant change. If the scsi-scanning thread fails to initialize but the host has successfully been added, we need to quiesce the driver before removing the host. After all, it's possible that scanning could have been initiated from somewhere else, such as userspace -- very low probability, but it's easily handled by calling the new subroutine.

This patch started life as as531 from Alan Stern. It has been rediffed against the latest tree. The SCSI people have deprecated the use of scsi_cmnd.serial_number for anything other than printk. Worse than that, the SCSI core doesn't always increment the number (when the error handler is running, for example). So this patch creates a locally-stored value for use in bulk-only tags. The net result is a simplification, since we no longer have to save & restore the serial_number value while autosensing.

This patch removes support for user-provided platform-specific hardware reset and clock starting/stopping functions. Hardware reset was needed earlier as getting the software reset working was tricky due to the lack of documentation. Recently, a number of people using isp116x have said the software reset is working for them. I haven't heard of anybody using the clock starting/stopping.

Back out Axboe-style quasi-S/G and replace it with one command and repeated URBs. This is similar to what usb-storage does, only instead of a few URBs allocated together, one URB is reused. Jens's idea was very nice, but it collapsed when I had to support packet commads for CD burning. I cannot issue two or more packet commands where application expected only one. However, burning does not work completely yet. The cdrecord starts, recognizes the device, then aborts without writing a TOC.

This the quasi-S/G patch for ub as suggested by Jens Axboe at OLS and implemented that night before 4 a.m. Surprisingly, it worked right away... Alas, I had to skip some OLS partying, but it was for the good cause. Now the speed of ub is quite acceptable even on partitions with small block size. The ub does not really support S/G. Instead, it just tells the block layer that it does. Then, most of the time, the block layer merges requests and passes single-segmnent requests down to ub; everything works as before. Very rarely ub gets an unmerged S/G request. In such case, it issues several commands to the device. I added a small array of counters to monitor the merging (sg_stat). This may be dropped later.

We are currently working on a pam_console/resmgr replacement driven by udev and a pam-helper. It applies ACL's to device nodes, which is required for modern desktop functionalty like "Fast User Switching" or multiple local login support. New patch with its own major. I've succesfully disabled usbfs and use real nodes only on my box. With: "export USB_DEVFS_PATH=/dev/bus/usb" libusb picks up the udev managed nodes instead of reading usbfs files.

To recap: My new G4 powerbook has a bluetooth device that boots up in what apppears to be a compatability mode - it looks exactly like an HID keyboard/mouse device. A special command sequence is sent to switch it into full bluetooth mode. When this occurs the original HID device vanishes, and a new (bluetooth HID) USB device appears on the bus with a different product ID. The original thread is here: http://sourceforge.net/mailarchive/message.php?msg_id=12532263 The attached patch adds the device to the hid-core quirks so that hid-core ignores it.

This patch for the ftdi_sio driver adds a bunch of new devices and fixes an incorrect PID: o Fix PID for ELV UO100 (the PID was in fact for ELV UR100). o Add PID ELV UR100 (see above) and ELV ALC 8500 Expert. o Add a whole bunch of other PIDs for ELV USB devices, commented out for now as they may be used by other drivers eventually. (Christian Abt of ELV.de submitted a full list of devices including an indication of which set of drivers are used by default in the MS Windows world. We decided to comment out the devices that use FTDI's D2XX Windows drivers by default.) o Add PIDs for eight devices from Xsens Technologies BV (submitted in a patch against 2.6.12.2 by Patrick Riphagen). o Add PID for Falcom Samba GPRS modem (submitted by Sebastian Schubert).

This patch centralizes the assignment of bcdDevice numbers for different gadget controllers. This won't improve the object code at all, but it does save a lot of repetitive and error-prone source code ... and will simplify the work of supporting a new controller driver, since most new gadget drivers will no longer need patches (unless some hardware quirks limit USB protocol messaging).

When we copy 32bit ->msg_control contents to kernel, we walk the same userland data twice without sanity checks on the second pass. Second version of this patch: the original broke with 64-bit arches running 32-bit-compat-mode executables doing sendmsg() syscalls with unaligned CMSG data areas Another thing is that we use kmalloc() to allocate and sock_kfree_s() to free afterwards; less serious, but also needs fixing.

ICH6 spec defines the PORT_ bits as: PORT_ENABLED (R/W): 0 = Disabled. The port is in the off state and cannot detect any devices. 1 = Enabled. The port can transition between the on, partial, and slumber states and can detect devices. PORT_PRESENT (R/O) The status of this bit may change at any time. This bit is cleared when the port is disabled via PORT_ENABLED. This bit is not cleared upon surprise removal of a device. So from a textual view it is not necessary that PORT_PRESENT _must_ be set, especially if a device detection has to be done anyway. And, in fact, this is the view that ACER has been taken with its new Laptops (e.g. Travelmate 4150). And the definition of PORT_ENABLED / PORT_PRESENT is mixed up, btw.
