[PATCH] USB: Fix HP8200 detection in shuttle_usbat

Adding flash-device support to the shuttle_usbat driver in 2.6.11
introduced the need to detect which type of device we are dealing with:
CDRW drive, or flash media reader.

The detection routine used turned out to not work for HP8200 CDRW users,
who saw their devices being detected as a flash disk.

This patch (which has been tested on both flash and cdrom) removes some
unnecessary code, moves device detection to much later during
initialization, and introduces a new detection routine which appears to
work.

[PATCH] USB: URB_ASYNC_UNLINK flag removed from the kernel

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

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

Disconnect processing in usb-storage naturally divides into two parts:

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

requests and passes single-segmnent requests down to ub; everything

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.

[PATCH] fix klist semantics for lists which have elements removed on traversal

The problem is that klists claim to provide semantics for safe traversal of
lists which are being modified.  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.

[PATCH] pivot_root() circular reference fix

Fix http://bugzilla.kernel.org/show_bug.cgi?id=4857

When pivot_root is called from an init script in an initramfs environment,
it causes a circular reference in the mount tree.

The cause of this is that pivot_root() is not prepared to handle pivoting
an unattached mount.  In an initramfs environment, rootfs is the root of
the namespace, and so it is not attached.

the current root or the new root is detached.

[PATCH] kprobes: fix handling of simultaneous probe hit/unregister

This patch fixes a bug in kprobes's handling of a corner case on i386 and
x86_64.  On an SMP system, if one CPU unregisters a kprobe just after
another CPU hits that probepoint, kprobe_handler() on the latter CPU sees
that the kprobe has been unregistered, and attempts to let the CPU continue
as if the probepoint hadn't been hit.  The bug is that on i386 and x86_64,
we were neglecting to set the IP back to the beginning of the probed
instruction.  This could cause an oops or crash.

This bug doesn't exist on ppc64 and ia64, where a breakpoint instruction
leaves the IP pointing to the beginning of the instruction.  I don't know
about sparc64.  (Dave, could you please advise?)

This fix has been tested on i386 and x86_64 SMP systems.  To reproduce the
problem, set one CPU to work registering and unregistering a kprobe
repeatedly, and another CPU pounding the probepoint in a tight loop.

from the replaced instruction, else if we find that it is still a break,

inserted by other than kprobe(may be kernel debugger).

[PATCH] Kprobes: prevent possible race conditions generic

There are possible race conditions if probes are placed on routines within the
kprobes files and routines used by the kprobes.  For example if you put probe
on get_kprobe() routines, the system can hang while inserting probes on any
routine such as do_fork().  Because while inserting probes on do_fork(),
register_kprobes() routine grabs the kprobes spin lock and executes
get_kprobe() routine and to handle probe of get_kprobe(), kprobes_handler()
gets executed and tries to grab kprobes spin lock, and spins forever.  This
patch avoids such possible race conditions by preventing probes on routines
within the kprobes file and routines used by kprobes.

I have modified the patches as per Andi Kleen's suggestion to move kprobes
routines and other routines used by kprobes to a seperate section
.kprobes.text.

Also moved page fault and exception handlers, general protection fault to
.kprobes.text section.

These patches have been tested on i386, x86_64 and ppc64 architectures, also
compiled on ia64 and sparc64 architectures.
