[patch 01/32] [IA64] Build fix for __early_pfn_to_nid() undefined link error

[Greg KH]

From: Tony Luck <tony.luck@intel.com>

commit 334f85b647bc46ff4d27ace55aa65f44d6a2f4db upstream.

ia64 only defines __early_pfn_to_nid() for SPARSEMEM && NUMA configurations,
so the recent:

	commit: f2dbcfa738368c8a40d4a5f0b65dc9879577cb21
	mm: clean up for early_pfn_to_nid()

ends up with some link problems for certain configuration files.

Fix arch/ia64/Kconfig to only define HAVE_ARCH_EARLY_PFN_TO_NID in the
cases where we do provide this function.

From: Linus Torvalds <torvalds@linux-foundation.org>

commit 68df3755e383e6fecf2354a67b08f92f18536594 upstream.

This makes sure that gcc doesn't try to optimize away wrapping
arithmetic, which the kernel occasionally uses for overflow testing, ie
things like

	if (ptr + offset < ptr)

which technically is undefined for non-unsigned types. See

	http://bugzilla.kernel.org/show_bug.cgi?id=12597

for details.

Not all versions of gcc support it, so we need to make it conditional
(it looks like it was introduced in gcc-3.4).

From: J. Bruce Fields <bfields@citi.umich.edu>

commit 76a67ec6fb79ff3570dcb5342142c16098299911 upstream.

Since creating a device node is normally an operation requiring special
privilege, Igor Zhbanov points out that it is surprising (to say the
least) that a client can, for example, create a device node on a
filesystem exported with root_squash.

So, make sure CAP_MKNOD is among the capabilities dropped when an nfsd
thread handles a request from a non-root user.

Although this operation is unsupported by our implementation
we still need to provide an encode routine for it to
merely encode its (error) status back in the compound reply.

Thanks for Bill Baker at sun.com for testing with the Sun
OpenSolaris' client, finding, and reporting this bug at
Connectathon 2009.

commit 6af845e4eb36fb91b322aaf77ec1cab2220a48ad upstream.

In snd_free_sgbuf_pags(), vunmap() is called after releasing the SG
pages, and it causes errors on Xen as Xen manages the pages
differently.  Although no significant errors have been reported on
the actual hardware, this order should be fixed other way round,
first vunmap() then free pages.

From: Tejun Heo <tj@kernel.org>

commit e9c1670c2a14ef9cc20d86b24b829f3947aad34e upstream.

Samsung DB-P70 somehow botched the first ICH9 SATA port.  The board
doesn't expose the first port but somehow SStatus reports link online
while failing SRST protocol leading to repeated probe failures and
thus long boot delay.

Because the BIOS doesn't carry any identifying DMI information, the
port can't be blacklisted safely.  Fortunately, the controller does
have subsystem vendor and ID set.  It's unclear whether the subsystem
IDs are used only for the board but it can be safely worked around by
disabling SIDPR access and just using SRST works around the problem.
Even when the workaround is triggered on an unaffected board the only
side effect will be missing SCR access.

In the async encryption-complete function (kcryptd_async_done), the

crypto_ablkcipher_encrypt/decrypt.  Only crypto_async_request->data is
guaranteed to be same as the one passed in.  The current
kcryptd_async_done uses the passed-in crypto_async_request directly
which may cause the AES-NI-based AES algorithm implementation to panic.

This patch fixes this bug by only using crypto_async_request->data,
which points to dm_crypt_request, the crypto_async_request passed in.
The original data (convert_context) is gotten from dm_crypt_request.

[patch 12/32] dm ioctl: validate name length when renaming

[Greg KH]

[-- Attachment #1: dm-ioctl-validate-name-length-when-renaming.patch --]
[-- Type: text/plain, Size: 1394 bytes --]

2.6.27-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Milan Broz <mbroz@redhat.com>

commit bc0fd67feba2e0770aad85393500ba77c6489f1c upstream.

When renaming a mapped device validate the length of the new name.

The rename ioctl accepted any correctly-terminated string enclosed
within the data passed from userspace.  The other ioctls enforce a
size limit of DM_NAME_LEN.  If the name is changed and becomes longer
than that, the device can no longer be addressed by name.

Fix it by properly checking for device name length (including
terminating zero).

dm-io calls bio_get_nr_vecs to get the maximum number of pages to use
for a given device.  It allocates one additional bio_vec to use
internally but failed to respect BIO_MAX_PAGES, so fix this.

[Greg KH]

[-- Attachment #1: eventfd-remove-fput-call-from-possible-irq-context.patch --]
[-- Type: text/plain, Size: 4253 bytes --]

2.6.27-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Davide Libenzi <davidel@xmailserver.org>

commit 87c3a86e1c220121d0ced59d1a71e78ed9abc6dd upstream.

Remove a source of fput() call from inside IRQ context.  Myself, like Eric,
wasn't able to reproduce an fput() call from IRQ context, but Jeff said he was
able to, with the attached test program.  Independently from this, the bug is
conceptually there, so we might be better off fixing it.  This patch adds an
optimization similar to the one we already do on ->ki_filp, on ->ki_eventfd.
Playing with ->f_count directly is not pretty in general, but the alternative
here would be to add a brand new delayed fput() infrastructure, that I'm not
sure is worth it.

From: Martin Schwidefsky <schwidefsky@de.ibm.com>

commit 4fa81ed27781a12f6303b9263056635ae74e3e21 upstream.

The implementation of __div64_31 for G5 machines is broken. The comments
in __div64_31 are correct, only the code does not do what the comments
say. The part "If the remainder has overflown subtract base and increase
the quotient" is only partially realized, the base is subtracted correctly
but the quotient is only increased if the dividend had the last bit set.
Using the correct instruction fixes the problem.

From: Mathieu Chouquet-Stringer <mchouque@free.fr>

commit b36a50f92d1c4300a88f606b4d2bbdc4f442a2d7 upstream.

Looking at the source, there seems to be a missing * to match my DMI
string.  I mean for newer IBM and Lenovo's laptops you match either one
of the following:
MODULE_ALIAS("dmi:bvnIBM:*:svnIBM:*:pvrThinkPad*:rvnIBM:*");
MODULE_ALIAS("dmi:bvnLENOVO:*:svnLENOVO:*:pvrThinkPad*:rvnLENOVO:*");

While for older Thinkpads, you do this (for instance):
IBM_BIOS_MODULE_ALIAS("1[0,3,6,8,A-G,I,K,M-P,S,T]");

with IBM_BIOS_MODULE_ALIAS being MODULE_ALIAS("dmi:bvnIBM:bvr" __type "ET??WW")

Note there's no * terminating the string.  As result, udev doesn't load
anything because modprobe cannot find anything matching this (my
machine actually):

From: Andy Walls <awalls@radix.net>

commit cd8f894eacf13996d920fdd2aef1afc55156b191 upstream.

Analog support for HVR-1250 has not been completed, but does exist for
the HVR-1800.

Since both cards use the same driver, it tries to create the analog
dev for both devices, which is not possible.

This causes a NULL error to show up in video_open and mpeg_open.

-Mark

Iterations through the cx23885_devlist must check for NULL
pointers as some supported devices only have DVB support at the moment.
Mark Jenks encoutered an Oops in a system with both an HVR-1250 and HVR-1800
installed.

[patch 18/32] Fix misreporting of #cores as #hyperthreads for Q9550

From: Joe Korty <joe.korty@ccur.com>

Fix misreporting of #cores for the Intel Quad Core Q9550.

For the Q9550, in x86_64 mode, /proc/cpuinfo mistakenly
reports the #cores present as the #hyperthreads present.
i386 mode was not examined but is assumed to have the
same problem.

A backport of the following three 2.6.29-rc1 patches
fixes the problem:

[patch 19/32] powerpc: Remove extra semicolon in fsl_soc.c

[Greg KH]

[-- Attachment #1: powerpc-remove-extra-semicolon-in-fsl_soc.c.patch --]
[-- Type: text/plain, Size: 961 bytes --]

2.6.27-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Johns Daniel <jdaniel@computer.org>

TSEC/MDIO will not work with older device trees because of a semicolon
at the end of a macro resulting in an empty for loop body.

This fix only applies to 2.6.28; this code is gone in 2.6.29, according
to Grant Likely!

[Greg KH]

[-- Attachment #1: usb-ehci-expedite-unlinks-when-the-root-hub-is-suspended.patch --]
[-- Type: text/plain, Size: 1538 bytes --]

2.6.27-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Alan Stern <stern@rowland.harvard.edu>

commit 391016f6e2fe3b9979b4c6880a76e5e434d6947c upstream.

This patch (as1225) fixes a bug in ehci-hcd.  The condition for
whether unlinked QHs can become IDLE should not be that the controller
is halted, but rather that the controller isn't running.  In other
words when the root hub is suspended, the hardware doesn't own any
QHs.

This fixes a problem that can show up during hibernation: If a QH is
only partially unlinked when the root hub is frozen, then when the
root hub is thawed the QH won't be in the IDLE state.  As a result it
can't be used properly for new URB submissions.

[patch 21/32] USB: EHCI: Fix isochronous URB leak

[Greg KH]

[-- Attachment #1: usb-ehci-fix-isochronous-urb-leak.patch --]
[-- Type: text/plain, Size: 2714 bytes --]

2.6.27-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Karsten Wiese <fzuuzf@googlemail.com>

commit 508db8c954d55ed30f870d2c24d741ba6269d13c upstream.

ehci-hcd uses usb_get_urb() and usb_put_urb() in an unbalanced way causing
isochronous URB's kref.counts incrementing once per usb_submit_urb() call.
The culprit is *usb being set to NULL when usb_put_urb() is called after URB
is given back.
Due to other fixes there is no need for ehci-hcd to deal with usb_get_urb()
nor usb_put_urb() anymore, so patch removes their usages in ehci-hcd.
Patch also makes ehci_to_hcd(ehci)->self.bandwidth_allocated adjust, if a
stream finishes.

commit 0cc6bfe901b946df125d8e37186d8e45f876457d upstream.

The generic cdc-acm driver is now the best one to handle Sony Ericsson
F3507g-based devices (which the Dell 5530 is a rebrand of), now that all
the pieces are in place (ie, cac477e8f1038c41b6f29d3161ce351462ef3df7).
Removing the IDs from option allows cdc-acm to handle the device.

commit 8a0845c51b2e300f5204a323b874f7f58ea0eff7 upstream.

The "c-enter" USB to Toshiba 1.8" IDE enclosure needs special treatment
to work flawlessly. This patch is absolutely trivial, as the integrated
USB-IDE bridge is already identified to be an "unusual" device, only the
bcdDevice is different (lower) to the bcdDeviceMin already included in
the kernel.
It is a Prolific 2507 bridge.

[patch 30/32] USB: unusual_devs: Add support for GI 0431 SD-Card interface

From: Jan Dumon <j.dumon@option.com>

commit c497e715f93d148d751c055401568684eea0bf6b upstream.

Enable the SD-Card interface on the GI 0431 HSUPA stick 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.

[patch 32/32] USB: usbfs: keep async URBs until the device file is closed

[Greg KH]

[-- Attachment #1: usb-usbfs-keep-async-urbs-until-the-device-file-is-closed.patch --]
[-- Type: text/plain, Size: 2221 bytes --]

2.6.27-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Alan Stern <stern@rowland.harvard.edu>

commit 6ff10464096540e14d7575a72c50d0316d003714 upstream.

The usbfs driver manages a list of completed asynchronous URBs.  But
it is too eager to free the entries on this list: destroy_async() gets
called whenever an interface is unbound or a device is removed, and it
deallocates the outstanding struct async entries for all URBs on that
interface or device.  This is wrong; the user program should be able
to reap an URB any time after it has completed, regardless of whether
or not the interface is still bound or the device is still present.

This patch (as1222) moves the code for deallocating the completed list
entries from destroy_async() to usbdev_release().  The outstanding
entries won't be freed until the user program has closed the device
file, thereby eliminating any possibility that the remaining URBs
might still be reaped.

This fixes a bug in which a program can hang in the USBDEVFS_REAPURB
ioctl when the device is unplugged.
