      usb-storage: revert DMA-alignment change for Wireless USB · f756cbd4
      Alan Stern 提交于
      This patch (as1110) reverts an earlier patch meant to help with
      Wireless USB host controllers.  These controllers can have bulk
      maxpacket values larger than 512, which puts unusual constraints on
      the sizes of scatter-gather list elements.  However it turns out that
      the block layer does not provide the support we need to enforce these
      constraints; merely changing the DMA alignment mask doesn't help.
      Hence there's no reason to keep the original patch.  The Wireless USB
      problem will have to be solved a different way.
      
      In addition, there is a reason to get rid of the earlier patch.  By
      dereferencing a pointer stored in the ep_in array of struct
      usb_device, the current code risks an invalid memory access when it
      runs concurrently with device removal.  The members of that array are
      cleared before the driver's disconnect method is called, so it should
      not try to use them.

      USB: fix usb_reset_device and usb_reset_composite_device(take 3) · 742120c6
      Ming Lei 提交于
      This patch renames the existing usb_reset_device in hub.c to
      usb_reset_and_verify_device and renames the existing
      usb_reset_composite_device to usb_reset_device. Also the new
      usb_reset_and_verify_device does't need to be EXPORTED .
      
      The idea of the patch is that external interface driver
      should warn the other interfaces' driver of the same
      device before and after reseting the usb device. One interface
      driver shoud call _old_ usb_reset_composite_device instead of
      _old_ usb_reset_device since it can't assume the device contains
      only one interface. The _old_ usb_reset_composite_device
      is safe for single interface device also. we rename the two
      functions to make the change easily.
      
      This patch is under guideline from Alan Stern.

      USB: remove interface parameter of usb_reset_composite_device · 625f6949
      Ming Lei 提交于
      From the current implementation of usb_reset_composite_device
      function, the iface parameter is no longer useful. This function
      doesn't do something special for the iface usb_interface,compared
      with other interfaces in the usb_device. So remove the parameter
      and fix the related caller.

      usb-storage: implement "soft" unbinding · 543f7810
      Alan Stern 提交于
      This patch (as1092) implements "soft" unbinding for usb-storage.  When
      the disconnect routine is called, all commands and reset delays are
      allowed to complete normally until after scsi_remove_host() returns.
      This means that the commands needed for an orderly shutdown will be
      sent through to the device.
      
      Unlike before, the driver will now execute every command that it
      accepts.  Hence there's no need for special code to catch unexecuted
      commands and fail them.
      
      The new sequence of events when disconnect runs goes as follows:
      
      	If the device is truly unplugged, set the DISCONNECTING
      	flag so we won't try to access it any more.
      
      	If the SCSI-scanning thread hasn't started up yet, prevent
      	it from doing anything by setting the new DONT_SCAN flag.
      	Then wake it up and wait for it to terminate.
      
      	Remove the SCSI host.  This unbinds the upper-level drivers,
      	doing an orderly shutdown.  Commands sent to quiesce the
      	device will be transmitted normally, unless the device is
      	unplugged.
      
      	Set the DISCONNECTING flag so that we won't accept any new
      	commands that might get submitted (there aren't supposed to be
      	any) and we won't try to access the device for resets.
      
      	Tell the control thread to exit by waking it up with no
      	pending command, and wait for it to terminate.
      
      	Go on to do all the other normal stuff: releasing resources,
      	freeing memory, and so on.

      usb-storage: separate dynamic flags from fixed flags · 7e4d6c38
      Alan Stern 提交于
      This patch (as1089) separates out the dynamic atomic bitflags and the
      static bitfields in usb-storage.  Until now the two sorts of flags
      have been sharing the same word; this has always been awkward.
      
      To help prevent possible confusion, the two new fields each have a
      different name from the original.  us->fflags contains the fixed
      bitfields (mostly taken from the USB ID table in unusual_devs.h), and
      us->dflags contains the dynamic atomic bitflags (used with set_bit,
      test_bit, and so on).

      USB: unusual_devs: Add support for GI 0401 SD-Card interface · e7c6f80f
      Filip Aben 提交于
      Enables the SD-Card interface on the GI 0401 HSUPA card from Option.
      
      The unusual_devs.h entry is necessary because the device descriptor is
      vendor-specific. That prevents usb-storage from binding to it as an
      interface driver.
      
      This revised patch adds a small comment explaining why and reduces the
      rev range.

      [SCSI] Let scsi_cmnd->cmnd use request->cmd buffer · 64a87b24
      Boaz Harrosh 提交于
       - struct scsi_cmnd had a 16 bytes command buffer of its own.
         This is an unnecessary duplication and copy of request's
         cmd. It is probably left overs from the time that scsi_cmnd
         could function without a request attached. So clean that up.
      
       - Once above is done, few places, apart from scsi-ml, needed
         adjustments due to changing the data type of scsi_cmnd->cmnd.
      
       - Lots of drivers still use MAX_COMMAND_SIZE. So I have left
         that #define but equate it to BLK_MAX_CDB. The way I see it
         and is reflected in the patch below is.
         MAX_COMMAND_SIZE - means: The longest fixed-length (*) SCSI CDB
                            as per the SCSI standard and is not related
                            to the implementation.
         BLK_MAX_CDB.     - The allocated space at the request level
      
       - I have audit all ISA drivers and made sure none use ->cmnd in a DMA
         Operation. Same audit was done by Andi Kleen.
      
      (*)fixed-length here means commands that their size can be determined
         by their opcode and the CDB does not carry a length specifier, (unlike
         the VARIABLE_LENGTH_CMD(0x7f) command). This is actually not exactly
         true and the SCSI standard also defines extended commands and
         vendor specific commands that can be bigger than 16 bytes. The kernel
         will support these using the same infrastructure used for VARLEN CDB's.
         So in effect MAX_COMMAND_SIZE means the maximum size command
         scsi-ml supports without specifying a cmd_len by ULD's
