* [PATCH] USB: URB_ASYNC_UNLINK flag removed from the kernelAlan Stern2005-09-0916-63/+20Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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."

* [PATCH] USB Storage: wedge SCSI revision at 2 for usb-storage devicesMatthew Dharm2005-09-091-0/+8
| | | | | | | | | | | | | | | | | 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.

* [PATCH] USB Storage: add support for Maxtor One-Touch buttonMatthew Dharm2005-09-096-1/+242
| | | | | | | | | | | | | | 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.

* [PATCH] USB Storage: close a race condition in disconnect near queuecommandMatthew Dharm2005-09-091-0/+13
| | | | | | | | | | | | | | | | | | 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.

* [PATCH] USB Storage: close a race condition in disconnect near probeMatthew Dharm2005-09-091-27/+35
| | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] USB Storage: remove dependency on SCSI-provided serial/tag numberMatthew Dharm2005-09-092-8/+3Star
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

The failure case is when traversal of a list causes element removal (a fairly common case). The issue is that although the list node is refcounted, if it is embedded in an object (which is universally the case), then the object will be freed regardless of the klist refcount leading to slab corruption because the klist iterator refers to the prior element to get the next. The solution is to make the klist take and release references to the embedding object meaning that the embedding object won't be released until the list relinquishes the reference to it.

It looks like SGI use the same FC vendor and they already have a workaround for this issue. The following patch adds the IBM version of it.

The symptom is a repeated Unit Attention with ASC=0x28 (Not Ready to Ready transition). The patch will wait for up to 5 seconds for such devices to become ready. Normal devices won't send the repeated Unit Attention sense key and hence won't trigger the patch. This fixes a problem with James Roberts-Thomson's USB device, and I've seen several reports of other devices exhibiting the same symptoms -- presumably they will be helped as well.

| | | * | [SCSI] return success after retries in scsi_eh_turAlan Stern2005-09-071-1/+3

The scsi_eh_tur function gives up after one round of retrying; after that it decides that more error recovery is needed. However TUR is liable to report sense data indicating a retry is needed when in fact error recovery has succeeded. A typical example might be SK=2, ASC=4, ASCQ=1 (Logical unit in process of becoming ready). The mere fact that we were able to get a sensible reply to the TUR should indicate that the device is working well enough to stop error recovery. I ran across a case back in January where this happened. A CD-ROM drive timed out the INQUIRY command, and a device reset fixed the blockage. But then the drive kept responding with 2/4/1 -- because it was spinning up I suppose -- until the error handler gave up and placed it offline. If the initial INQUIRY had received the 2/4/1 instead, everything would have worked okay. It doesn't seem reasonable for things to fail just because the error handler had started running.
