      sctp: Various invalid address check fixes. (jgrimm) · dec5c911
      Jon Grimm authored
      1) Need to check inside INIT chunks for addresses, not just
      INIT-ACK otherwise we don't recognize restart.
      2) The address check logic isn't being excercised early enough
      in the restart.  Per the impl-guide it needs to happen as early
      as INIT processing in COOKIE-ECHOED state. 
      3) Eliminate more uses of deprecated sctpParam_t

      [PATCH] sg.c and USER_HZ, kernel 2.5.37 · 8885e375
      Rolf Fokkens authored
      Hi!
      
      Since the introduction of USER_HZ the SG_[GS]ET_TIMEOUT ioctls may have
      a serious BUG as userspace uses a different HZ from the HZ in kernelspace.
      
      In x86 HZ=1000 and USER_HZ=100, resulting in confusing timouts as the
      kernel measures time 10 times as fast as userspace.
      
      This patch is an attempt to fix this by transforming USER_HZ based timing to
      HZ based timing before storing it in timeout. To make sure that SG_GET_TIMEOUT
      and SG_SET_TIMEOUT behave consistently a field timeout_user is added which
      stores the exact value that's passed by SG_SET_TIMEOUT and it's returned on
      SG_GET_TIMEOUT.

      scsi_initialise_merge_fn() will only set highio if ->type == TYPE_DISK. · 2b562242
      Andrew Morton authored
      But it's called from scsi_add_lun()->scsi_alloc_sdev() before the type
      is known.  The type is -1 all the time in scsi_initialise_merge_fn()
      and scsi always bounces.
      
      This patch makes it do the right thing - just enable block-highmem for
      all scsi devices.
      
      Jens had this to say:
      
      "I guess that block-highmem has been around long enough, that I can
       use the term 'historically' at least in the kernel sense :-)
      
       This extra check was added for IDE because each device type driver
       (ide-disk, ide-cd, etc) needed to be updated to not assume virtual
       mappings of request data was valid.  I only did that for ide-disk,
       since this is the only one where bounce buffering really hurt
       performance wise.  So while ide-cd and ide-tape etc could have been
       updated, I deemed it uninteresting and not worthwhile.
      
       Now, this was just carried straight into the scsi counter parts,
       conveniently, because of laziness.  A quick glance at sr shows that it
       too can aviod bouncing easily (no changes needed).  st may need some
       changes, though.  So again, for scsi it was a matter of not impacting
       existing code in 2.4 too much.
      
       So TYPE_DISK check can be killed in 2.5 if someone does the work of
       checking that it is safe.  I'm not so sure it will make eg your SCSI
       CD-ROM that much faster :-)"

      [PATCH] usb_sg_{init,wait,cancel}() · 1e4fece8
      David Brownell authored
      Here are the scatterlist primitives there's been mail about before.
      Now the code has passed basic sanity testing, and is ready to merge
      into Linus' tree to start getting wider use.  Greg, please merge!
      
      To recap, the routines are a utility layer packaging several usb
      core facilities to improve system performance.  It's synchronous.
      The code uses functionality that drivers could use already, but
      generally haven't:
      
          - Request queueing.  This is a big performance win.  It lets
            device drivers help the hcds avoid wasted i/o bandwidth, by
            eliminating irq and scheduling latencies between requests.  It
            can make a huge difference at high speed, when the latencies
            often exceed the time to handle each i/o request!
      
          - The new usb_map_sg() primitives, leveraging IOMMU hardware
            if it's there (better than entry-at-a-time mapping).
      
          - URB_NO_INTERRUPT transfer flag, a hint to hcds that they
            can avoid a 'success irq' for this urb.  Only the urb for
            the last scatterlist entry really needs an IRQ, the others
            can be eliminated or delayed.  (OHCI uses this today, and
            any HCD can safely ignore it.)
      
      The particular functionality in these APIs seemed to meet Matt's
      requirements for usb-storage, so I'd hope the 2.5 usb-storage
      code will start to use these routines in a while.  (And maybe
      those two scanner drivers: hpusbscsi, microtek.)
      
      Brief summary of testing:  this code seems correct for normal
      reads and writes, but the fault paths (including cancelation)
      haven't been tested yet.  Both EHCI and OHCI seem to be mostly
      OK with these more aggressive queued loads, but may need small
      updates (like the two I sent yesterday).  Unfortunately I have
      to report that UHCI and urb queueing will sometimes lock up my
      hardware (PIIX4), so while we're lots better than 2.4 this is
      still a bit of a trouble spot for now.
      
      I'll be making some testing software available shortly, which
      will help track down remaining HCD level problems by giving the
      queuing APIs (and some others!) a more strenuous workout than
      most drivers will, in their day-to-day usage.

      [PATCH] USB-storage: problem clearing halts · 2eea1938
      Matthew Dharm authored
      Greg, attached is a patch designed for diagnostic purposes.  Please apply
      to the 2.5 tree -- yes, we'll be removing this at some point in the future.
      
      It appears that we have a problem clearing halts.  This patch causes a very
      clear message to be printed whenever a usb_stor_clear_halt() manages to
      work.  So far, I haven't seen such a thing happen.  And I've seen _lots_ of
      STALL conditions.
      
      This problem has likely been around for a while... however, it hasn't been
      noticed before because usb-storage was difficult to use because of other
      bugs.  Heck, the most recent 'bk pull' is the first one for me in _months_
      which let me boot all the way into X11.
      
      I'm going to hold my patch queue until this is resolved.  On my test setup,
      it's easy to see this failing.  I've tried with 4 different devices, with
      both UHCI and EHCI drivers.  I don't want to confuse this problem with
      other patches...
      
      'result' in this function always seems to be -32.  Which is odd, because
      control endpoints shouldn't do that.
      
      I'm open to suggestions as to where to look for this bug, but my instincts
      are telling me that this is a core or HCD issue, not a usb-storage issue.
      
      On a positive note, this means that the error-recovery system gets a good
      workout.

      [ARM] Fix sa1111 IRQ handling · 99afe913

      We must clear down all currently pending IRQs before servicing any
      IRQ on the chip.  This prevents immediate recursion into the

      [PATCH] ohci-hcd, paranoia · 86cdffc9
      David Brownell authored
      In a test where some memory corruption happened, I noticed an
      oops (null pointer exception in_irq) that's avoidable.  Here's
      a patch that avoids it ... anyone seeing the err() is likely
      to hang some process, but that's better than the alternative.
      (Also inlines some used-once routines, saving a bit of space
      to make up for the new diagnostic.)

      [PATCH] ehci-hcd, urb queuing · c5375618
      David Brownell authored
      In doing some more extensive testing of the urb queueing behavior,
      I noticed that (a) IOC wasn't always being set for each urb, while
      for now it needs to be set; (b) a qh patchup wasn't done quite
      where it should be.  This resolves those two issues, as well
      as making it a bit less noisy to unlink lots of urbs at the once.

      [PATCH] usbcore misc cleanup · 846f917c
      David Brownell authored
      This has minor usbcore cleanups:
      
      DOC:
          - the changes passing a usb_interface to driver probe() and disconnect()
            weren't reflected in their adjacent docs.  likewise they still said
            it was possible to get a null usb_device_id (no more).
      
          - the (root) hub API restrictions from rmk's ARM patch weren't
            flagged
      
          - mention the non-dma-coherent cache issue for usb_buffer_alloc()
      
          - mention disconnect() cleanup issue with usb_{control,bulk}_msg()
            [ you can't cancel those urbs from disconnect() ]
      
      CODE
          - make driver ioctl() use 'usb_interface' too ... this update
            also resolves an old 'one instance per device' bad assumption
      
          - module locking on driver->ioctl() was goofy, kept BKL way too
            long and didn't try_inc_mod_count() like the rest of usbcore
      
          - hcd unlink code treated iso inappropriately like interrupt;
            only interrupt still wants that automagic mode
      
          - move iso init out of ohci into shared submit_urb logic
      
          - remove interrupt transfer length restriction; hcds that don't
            handle packetization (just like bulk :) should be updated,
            but device drivers won't care for now.
