3.19.8-ckt9 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Wilson Kok <wkok@cumulusnetworks.com>
commit 41fc014332d91ee90c32840bf161f9685b7fbf2b upstream.
dump_rules returns skb length and not error.
But when family == AF_UNSPEC, the caller of dump_rules
assumes that it returns an error. Hence, when family == AF_UNSPEC,
we continue trying to dump on -EMSGSIZE errors resulting in
incorrect dump idx carried between skbs belonging to the same dump.
This results in fib rule dump always only dumping rules that fit
into the first skb.
This patch fixes dump_rules to return error so that we exit correctly
and idx is correctly maintained between skbs that are part of the
same dump.

In the IPv6 multicast routing code the mrt_lock was not being released correctly in the MFC iterator, as a result adding or deleting a MIF would cause a hang because the mrt_lock could not be acquired. This fix is a copy of the code for the IPv4 case and ensures that the lock is released correctly.

3.19.8-ckt9 -stable review patch. If anyone has any objections, please let me know. ------------------ From: "Tan, Jui Nee" <jui.nee.tan@intel.com> commit 02bc933ebb59208f42c2e6305b2c17fd306f695d upstream. On Intel Baytrail, there is case when interrupt handler get called, no SPI message is captured. The RX FIFO is indeed empty when RX timeout pending interrupt (SSSR_TINT) happens. Use the BIOS version where both HSUART and SPI are on the same IRQ. Both drivers are using IRQF_SHARED when calling the request_irq function. When running two separate and independent SPI and HSUART application that generate data traffic on both components, user will see messages like below on the console: pxa2xx-spi pxa2xx-spi.0: bad message state in interrupt handler This commit will fix this by first checking Receiver Time-out Interrupt, if it is disabled, ignore the request and return without servicing.

commit f50791ac1aca1ac1b0370d62397b43e9f831421a upstream.
It is needed to check EVENT_NO_RUNTIME_PM bit of dev->flags in
usbnet_stop(), but its value should be read before it is cleared
when dev->flags is set to 0.
The problem was spotted and the fix was provided by
Oliver Neukum <oneukum@suse.de>.

| In reply to | #1257302 |
3.19.8-ckt9 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Daniel Borkmann <daniel@iogearbox.net>
commit 1853c949646005b5959c483becde86608f548f24 upstream.
Ken-ichirou reported that running netlink in mmap mode for receive in
combination with nlmon will throw a NULL pointer dereference in
__kfree_skb() on nlmon_xmit(), in my case I can also trigger an "unable
to handle kernel paging request". The problem is the skb_clone() in
__netlink_deliver_tap_skb() for skbs that are mmaped.
I.e. the cloned skb doesn't have a destructor, whereas the mmap netlink
skb has it pointed to netlink_skb_destructor(), set in the handler
netlink_ring_setup_skb(). There, skb->head is being set to NULL, so
that in such cases, __kfree_skb() doesn't perform a skb_release_data()
via skb_release_all(), where skb->head is possibly being freed through
kfree(head) into slab allocator, although netlink mmap skb->head points
to the mmap buffer. Similarly, the same has to be done also for large
netlink skbs where the data area is vmalloced. Therefore, as discussed,
make a copy for these rather rare cases for now. This fixes the issue
on my and Ken-ichirou's test-cases.

From: Ludovic Desroches <ludovic.desroches@atmel.com>
commit d32dc9aa10c739363c775baf4499416b2e0dc11f upstream.
When masking/unmasking interrupts, mask_cache is updated and used later
for suspend/resume. Unfortunately, it always was the mask_cache
associated with the first irq chip which was updated. So when performing
resume, only irqs 0-31 could be enabled.

| In reply to | #1257302 |
3.19.8-ckt9 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Pablo Neira Ayuso <pablo@netfilter.org>
commit ba378ca9c04a5fc1b2cf0f0274a9d02eb3d1bad9 upstream.
Fix lookup of existing match/target structures in the corresponding list
by skipping the family check if NFPROTO_UNSPEC is used.
This is resulting in the allocation and insertion of one match/target
structure for each use of them. So this not only bloats memory
consumption but also severely affects the time to reload the ruleset
from the iptables-compat utility.
After this patch, iptables-compat-restore and iptables-compat take
almost the same time to reload large rulesets.

------------------
From: Robert Jarzmik <robert.jarzmik@free.fr>
commit 3c8f7710c1c44fb650bc29b6ef78ed8b60cfaa28 upstream.
The previous fix of pxa library support, which was introduced to fix the
library dependency, broke the previous SoC behavior, where a machine
code binding pxa2xx-ac97 with a coded relied on :
- sound/soc/pxa/pxa2xx-ac97.c
- sound/soc/codecs/XXX.c
For example, the mioa701_wm9713.c machine code is currently broken. The
"select ARM" statement wrongly selects the soc/arm/pxa2xx-ac97 for
compilation, as per an unfortunate fate SND_PXA2XX_AC97 is both declared
in sound/arm/Kconfig and sound/soc/pxa/Kconfig.
Fix this by ensuring that SND_PXA2XX_SOC correctly triggers the correct
pxa2xx-ac97 compilation.

From: Joseph Qi <joseph.qi@huawei.com>
commit 012572d4fc2e4ddd5c8ec8614d51414ec6cae02a upstream.
The order of the following three spinlocks should be:
dlm_domain_lock < dlm_ctxt->spinlock < dlm_lock_resource->spinlock
But dlm_dispatch_assert_master() is called while holding
dlm_ctxt->spinlock and dlm_lock_resource->spinlock, and then it calls
dlm_grab() which will take dlm_domain_lock.
Once another thread (for example, dlm_query_join_handler) has already
taken dlm_domain_lock, and tries to take dlm_ctxt->spinlock deadlock
happens.

commit a3b7470951ab49e5592d20c2bcfe5ee675221591 upstream.
When commit c4082d499fa2 ("ARM: omap2+: board-generic: clean up the
irq data from board file") cleaned up the direct usage of gic_of_init
and omap_intc_of_init, it failed to clean up the macros properly.
Since these macros are no longer used, lets just remove them.

From: Jani Nikula <jani.nikula@intel.com>
commit cd67d226ebd909d239d2c6e5a6abd6e2a338d1cd upstream.
The VBT MIPI Sequence Block version 3 has forward incompatible changes:
First, the block size in the header has been specified reserved, and the
actual size is a separate 32-bit value within the block. The current
find_section() function to will only look at the size in the block
header, and, depending on what's in that now reserved size field,
continue looking for other sections in the wrong place.
Fix this by taking the new block size field into account. This will
ensure that the lookups for other sections will work properly, as long
as the new 32-bit size does not go beyond the opregion VBT mailbox size.
Second, the contents of the block have been completely
changed. Gracefully refuse parsing the yet unknown data version.

| In reply to | #1257302 |
3.19.8-ckt9 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Doug Anderson <armlinux@m.disordat.com>
commit 7ae85dc7687c7e7119053d83d02c560ea217b772 upstream.
In (23a4e40 arm: kgdb: Handle read-only text / modules) we moved to
using patch_text() to set breakpoints so that we could handle the case
when we had CONFIG_DEBUG_RODATA. That patch used patch_text().
Unfortunately, patch_text() assumes that we're not in atomic context
when it runs since it needs to grab a mutex and also wait for other
CPUs to stop (which it does with a completion).
This would result in a stack crawl if you had
CONFIG_DEBUG_ATOMIC_SLEEP and tried to set a breakpoint in kgdb. The
crawl looked something like:
BUG: scheduling while atomic: swapper/0/0/0x00010007

It turns out that when we're in kgdb all the CPUs are stopped anyway
so there's no reason we should be calling patch_text(). We can
instead directly call __patch_text() which assumes that CPUs have
already been stopped.

From: Alex Williamson <alex.williamson@redhat.com>
commit da2d03ea27f6ed9d2005a67b20dd021ddacf1e4d upstream.
932c435caba8 ("PCI: Add dev_flags bit to access VPD through function 0")
added PCI_DEV_FLAGS_VPD_REF_F0. Previously, we set the flag on every
non-zero function of quirked devices. If a function turned out to be
different from function 0, i.e., it had a different class, vendor ID, or
device ID, the flag remained set but we didn't make VPD accessible at all.
Flip this around so we only set PCI_DEV_FLAGS_VPD_REF_F0 for functions that
are identical to function 0, and allow regular VPD access for any other
functions.

like nf_log_unset, nf_log_unregister must not reset the list of loggers.
Otherwise, a call to nf_log_unregister() will render loggers of other nf
protocols unusable:
iptables -A INPUT -j LOG
modprobe nf_log_arp ; rmmod nf_log_arp
iptables -A INPUT -j LOG
iptables: No chain/target/match by that name
