hid/apple: modern macbook airs use the standard apple function key translations
commit 21404b772a1c65f7b935b8c0fddc388a949f4e31 upstream.
This removes the use of the special "macbookair_fn_keys" keyboard
translation table for the MacBookAir4,x models (ie the 2011 refresh).
They use the standard apple_fn_keys[] translation. Apparently only the
old MacBook Air's need a different translation table.
This mirrors the change that commit da617c7cb915 ("HID: consolidate
MacbookAir 4,1 mappings") did for the WELLSPRING6A ones, but does it for
the WELLSPRING6 model used on the MacBookAir4,2.

mtd: nand_base: always initialise oob_poi before writing OOB data
commit f722013ee9fd24623df31dec9a91a6d02c3e2f2f upstream.
In nand_do_write_ops() code it is possible for a caller to provide
ops.oobbuf populated and ops.mode == MTD_OOB_AUTO, which currently
means that the chip->oob_poi buffer isn't initialised to all 0xFF.
The nand_fill_oob() method then carries out the task of copying
the provided OOB data to oob_poi, but with MTD_OOB_AUTO it skips
areas marked as unavailable by the layout struct, including the
bad block marker bytes.
An example of this causing issues is when the last OOB data read
was from the start of a bad block where the markers are not 0xFF,
and the caller wishes to write new OOB data at the beginning of
another block. In this scenario the caller would provide OOB data,
but nand_fill_oob() would skip the bad block marker bytes in
oob_poi before copying the OOB data provided by the caller.
This means that when the OOB data is written back to NAND,
the block is inadvertently marked as bad without the caller knowing.
This has been witnessed when using YAFFS2 where tags are stored
in the OOB.
To avoid this oob_poi is always initialised to 0xFF to make sure
no left over data is inadvertently written back to the OOB area.

As cryptd is depeneded on by other algorithms such as aesni-intel,
it needs to be registered before them. When everything is built
as modules, this occurs naturally. However, for this to work when
they are built-in, we need to use subsys_initcall in cryptd.

ext4: remove i_mutex lock in ext4_evict_inode to fix lockdep complaining
commit 8c0bec2151a47906bf779c6715a10ce04453ab77 upstream.
The i_mutex lock and flush_completed_IO() added by commit 2581fdc810
in ext4_evict_inode() causes lockdep complaining about potential
deadlock in several places. In most/all of these LOCKDEP complaints
it looks like it's a false positive, since many of the potential
circular locking cases can't take place by the time the
ext4_evict_inode() is called; but since at the very least it may mask
real problems, we need to address this.
This change removes the flush_completed_IO() and i_mutex lock in
ext4_evict_inode(). Instead, we take a different approach to resolve
the software lockup that commit 2581fdc810 intends to fix. Rather
than having ext4-dio-unwritten thread wait for grabing the i_mutex
lock of an inode, we use mutex_trylock() instead, and simply requeue
the work item if we fail to grab the inode's i_mutex lock.
This should speed up work queue processing in general and also
prevents the following deadlock scenario: During page fault,
shrink_icache_memory is called that in turn evicts another inode B.
Inode B has some pending io_end work so it calls ext4_ioend_wait()
that waits for inode B's i_ioend_count to become zero. However, inode
B's ioend work was queued behind some of inode A's ioend work on the
same cpu's ext4-dio-unwritten workqueue. As the ext4-dio-unwritten
thread on that cpu is processing inode A's ioend work, it tries to
grab inode A's i_mutex lock. Since the i_mutex lock of inode A is
still hold before the page fault happened, we enter a deadlock.

mtd: provide an alias for the redboot module name
commit d5de1907d0af22e1a02de2b16a624148517a39c2 upstream.
parse_mtd_partitions takes a list of partition types; if the driver
isn't loaded, it attempts to load it, and then it grabs the partition
parser. For redboot, the module name is "redboot.ko", while the parser
name is "RedBoot". Since modprobe is case-sensitive, attempting to
modprobe "RedBoot" will never work. I suspect the embedded systems that
make use of redboot just always manually loaded redboot prior to loading
their specific nand chip drivers (or statically compiled it in).

The offchannel code is currently broken - we should

the work's channel and channel_type are the same
as local->tmp_channel and local->tmp_channel_type.
However, if wk->chan_type and local->tmp_channel_type
coexist (e.g. have the same channel type), we won't
remain_off_channel.
This behavior was introduced by commit da2fd1f

netlink: validate NLA_MSECS length
commit c30bc94758ae2a38a5eb31767c1985c0aae0950b upstream.
L2TP for example uses NLA_MSECS like this:
policy:
[L2TP_ATTR_RECV_TIMEOUT] = { .type = NLA_MSECS, },
code:
if (info->attrs[L2TP_ATTR_RECV_TIMEOUT])
cfg.reorder_timeout = nla_get_msecs(info->attrs[L2TP_ATTR_RECV_TIMEOUT]);
As nla_get_msecs() is essentially nla_get_u64() plus the
conversion to a HZ-based value, this will not properly
reject attributes from userspace that aren't long enough
and might overrun the message.
Add NLA_MSECS to the attribute minlen array to check the
size properly.

powerpc/eeh: Fix /proc/ppc64/eeh creation
commit 8feaa43494cee5e938fd5a57b9e9bf1c827e6ccd upstream.
Since commit 188917e183cf9ad0374b571006d0fc6d48a7f447, /proc/ppc64 is a
symlink to /proc/powerpc/. That means that creating /proc/ppc64/eeh will
end up with a unaccessible file, that is not listed under /proc/powerpc/
and, then, not listed under /proc/ppc64/.
Creating /proc/powerpc/eeh fixes that problem and maintain the
compatibility intended with the ppc64 symlink.

powerpc/numa: Remove double of_node_put in hot_add_node_scn_to_nid
commit 6083184269fd723affca4f6340e491950267622a upstream.

of_find_node_by_type() loop does the of_node_put for us so we only
need the handle the case where we terminate the loop early.
As suggested by Stephen Rothwell we can do the of_node_put
unconditionally outside of the loop since of_node_put handles a
NULL argument fine.

VFS: we need to set LOOKUP_JUMPED on mountpoint crossing
commit a3fbbde70a0cec017f2431e8f8de208708c76acc upstream.
Mountpoint crossing is similar to following procfs symlinks - we do
not get ->d_revalidate() called for dentry we have arrived at, with
unpleasant consequences for NFS4.
Simple way to reproduce the problem in mainline:
cat >/tmp/a.c <<'EOF'
#include <unistd.h>
#include <fcntl.h>
#include <stdio.h>
main()
{
struct flock fl = {.l_type = F_RDLCK, .l_whence = SEEK_SET, .l_len = 1};
if (fcntl(0, F_SETLK, &fl))
perror("setlk");
}
EOF
cc /tmp/a.c -o /tmp/test
then on nfs4:
mount --bind file1 file2
/tmp/test < file1 # ok
/tmp/test < file2 # spews "setlk: No locks available"...
What happens is the missing call of ->d_revalidate() after mountpoint
crossing and that's where NFS4 would issue OPEN request to server.
The fix is simple - treat mountpoint crossing the same way we deal with
following procfs-style symlinks. I.e. set LOOKUP_JUMPED...

really care, and this probably makes it match previous semantics, so..

This is because bdev holds on to disk but disk doesn't pin the
associated queue. If a SCSI device is removed while the device is
still open, the sdev puts the base reference to the queue on release.
When the bdev is finally released, the associated queue is already
gone along with the bdi and bdev_inode_switch_bdi() ends up
dereferencing already freed bdi.
Even if it were not for this bug, disk not holding onto the associated
queue is very unusual and error-prone.
Fix it by making add_disk() take an extra reference to its queue and
put it on disk_release() and ensuring that disk and its fops owner are
put in that order after all accesses to the disk and queue are
complete.

NFS/sunrpc: don't use a credential with extra groups.
commit dc6f55e9f8dac4b6479be67c5c9128ad37bb491f upstream.
The sunrpc layer keeps a cache of recently used credentials and
'unx_match' is used to find the credential which matches the current
process.
However unx_match allows a match when the cached credential has extra
groups at the end of uc_gids list which are not in the process group list.
So if a process with a list of (say) 4 group accesses a file and gains
access because of the last group in the list, then another process
with the same uid and gid, and a gid list being the first tree of the
gids of the original process tries to access the file, it will be
granted access even though it shouldn't as the wrong rpc credential
will be used.

Fix for issue : While discovery is in progress, hot unplug and hot plug of

When a device is in the process of being detected at driver load time then
if it is removed, the device that is no longer present will not be added
to the list. So the code in _scsih_probe_sas() is rearranged as such so
the devices that failed to be detected are not added to the list.

Fix block queue and elevator memory leak in scsi_alloc_sdev
commit f7c9c6bb14f3104608a3a83cadea10a6943d2804 upstream.
When looking at memory consumption issues I noticed quite a
lot of memory in the kmalloc-2048 bucket:
OBJS ACTIVE USE OBJ SIZE SLABS OBJ/SLAB CACHE SIZE NAME
6561 6471 98% 2.30K 243 27 15552K kmalloc-2048
Over 15MB. slub debug shows that cfq is responsible for almost
all of it:
# sort -nr /sys/kernel/slab/kmalloc-2048/alloc_calls
6402 .cfq_init_queue+0xec/0x460 age=43423/43564/43655 pid=1 cpus=4,11,13
In scsi_alloc_sdev we do scsi_alloc_queue but if slave_alloc
fails we don't free it with scsi_free_queue.
The patch below fixes the issue:

st: fix race in st_scsi_execute_end
commit c68bf8eeaa57c852e74adcf597237be149eef830 upstream.
The call to complete() in st_scsi_execute_end() wakes up sleeping thread
in write_behind_check(), which frees the st_request, thus invalidating
the pointer to the associated bio structure, which is then passed to the
blk_rq_unmap_user(). Fix by storing pointer to bio structure into
temporary local variable.
This bug is present since at least linux-2.6.32.

tcm_loop: Add explict read buffer memset for SCF_SCSI_CONTROL_SG_IO_CDB
commit 8cd79f24350826b81e16990d9e12bc878e67d385 upstream.
This patch addresses an issue with buggy userspace code sending I/O
via scsi-generic that does not explictly clear their associated read
buffers. It adds an explict memset of the first SGL entry within
tcm_loop_new_cmd_map() for SCF_SCSI_CONTROL_SG_IO_CDB payloads that
are currently guaranteed to be a single SGL by target-core code.
This issue is a side effect of the v3.1-rc1 merge to remove the
extra memcpy between certain control CDB types using a contigious
+ cleared buffer in target-core, and performing a memcpy into the
SGL list within tcm_loop.
It was originally mainfesting itself by udev + scsi_id + scsi-generic
not properly setting up the expected /dev/disk/by-id/ symlinks because
the INQUIRY payload was containing extra bogus data preventing the
proper NAA IEEE WWN from being parsed by userspace.

The definition of TO_ATTR_NO in the non-SMP case is wrong. As the SMP
definition resolves to the correct value, just use this for both
cases.
Without this fix the temperature attributes are named temp0_* instead
of temp2_*, so libsensors won't pick them. Broken since kernel 3.0.

USB: Update last_busy time after autosuspend fails
commit b2c0a863e14676fa5760c6d828fd373288e2f64a upstream.
Originally, the runtime PM core would send an idle notification
whenever a suspend attempt failed. The idle callback routine could
then schedule a delayed suspend for some time later.
However this behavior was changed by commit
f71648d73c1650b8b4aceb3856bebbde6daa3b86 (PM / Runtime: Remove idle
notification after failing suspend). No notifications were sent, and
there was no clear mechanism to retry failed suspends.
This caused problems for the usbhid driver, because it fails
autosuspend attempts as long as a key is being held down. A companion
patch changes the PM core's behavior, but we also need to change the
USB core. In particular, this patch (as1493) updates the device's
last_busy time when an autosuspend fails, so that the PM core will
retry the autosuspend in the future when the delay time expires
again.

This caused problems for the usbhid driver, because it fails

this patch (as1492) adds a mechanism for retrying failed
autosuspends. If the callback routine updates the last_busy field so
that the next autosuspend expiration time is in the future, the
autosuspend will automatically be rescheduled.

kbuild: Fix help text not displayed in choice option.
commit 3f198dfee49d2e9c30583c62b0c79286c78c7b44 upstream.
Help text under choice menu is never displayed because it does not have
symbol name associated with it, however many kconfigs have help text
under choice, assuming that it will be displayed when user selects help.
for example in Kconfig if we have:
choice
prompt "Choice"
---help---
HELP TEXT ...
config A
bool "A"
config B
bool "B"
endchoice
Without this patch "HELP TEXT" is not displayed when user selects help
option when "Choice" is highlighted from menuconfig or xconfig or
gconfig.
This patch changes the logic in menu_get_ext_help to display help for
cases which dont have symbol names like choice.

Allow the user to override whether MSIs are enabled

on IGP chips as they tend not to work. However certain
IGP chips only seem to work with MSIs enabled.
I suspect this is a chipset or bios issue, but I'm not sure
what the proper fix is. This will at least make diagnosing
and working around the problem much easier.

drm/radeon: avoid bouncing connector status btw disconnected & unknown
commit 340764465aa4a586ca332e61ae64883e5ad6f183 upstream.
Since force handling rework of d0d0a225e6ad43314c9aa7ea081f76adc5098ad4
we could end up bouncing connector status btw disconnected and unknown.
When connector status change a call to output_poll_changed happen which
in turn ask again for detect but with force set.
So set the load detect flags whenever we report the connector as
connected or unknown this avoid bouncing btw disconnected and unknown.

If the device is unplugged while running, it is possible for a PCM
device to be closed after the disconnect callback has returned. This
means that kill_stream_urb() and disable_iso_interface() would try to
access already-invalid or freed USB data structures.
The function free_usb_related_resources() was intended to prevent this,
but forgot to clear the affected variables.

This resolves a regression seen by some users of bridging.
Some users use the bridge like a dummy device.
They expect to be able to put an IPv6 address on the device
with no ports attached. Although there are better ways of doing
this, there is no reason to not allow it.
Note: the bridge still will reflect the state of ports in the
bridge if there are any added.

should also return zero to avoid adding pages to the array at the wrong

powerpc: get_hugepte() don't put_page() the wrong page
commit 405e44f2e312dd5dd63e5a9f459bffcbcd4368ef upstream.
"page" may have changed to point to the next hugepage after the loop
completed, The references have been taken on the head page, so the
put_page must happen there too.
This is a longstanding issue pre-thp inclusion.
It's totally unclear how these page_cache_add_speculative and
pte_val(pte) != pte_val(*ptep) checks are necessary across all the
powerpc gup_fast code, when x86 doesn't need any of that: there's no way
the page can be freed with irq disabled so we're guaranteed the
atomic_inc will happen on a page with page_count > 0 (so not needing the
speculative check).
The pte check is also meaningless on x86: no need to rollback on x86 if
the pte changed, because the pte can still change a CPU tick after the
check succeeded and it won't be rolled back in that case. The important
thing is we got a reference on a valid page that was mapped there a CPU
tick ago. So not knowing the soft tlb refill code of ppc64 in great
detail I'm not removing the "speculative" page_count increase and the
pte checks across all the code, but unless there's a strong reason for
it they should be later cleaned up too.
If a pte can change from huge to non-huge (like it could happen with
THP) passing a pte_t *ptep to gup_hugepte() would also require to repeat
the is_hugepd in gup_hugepte(), but that shouldn't happen with hugetlbfs
only so I'm not altering that.

powerpc: remove superfluous PageTail checks on the pte gup_fast
commit 2839bdc1bfc0af76a2f0f11eca011590520a04fa upstream.
This part of gup_fast doesn't seem capable of handling hugetlbfs ptes,
those should be handled by gup_hugepd only, so these checks are
superfluous.
Plus if this wasn't a noop, it would have oopsed because, the insistence
of using the speculative refcounting would trigger a VM_BUG_ON if a tail
page was encountered in the page_cache_get_speculative().

xhci: If no endpoints changed, don't issue BW command.
commit 2dc3753997f3c80ce8b950242ab9bb3fb936acfd upstream.
Some alternate interface settings have no endpoints associated with them.
This shows up in some USB webcams, particularly the Logitech HD 1080p,
which uses the uvcvideo driver. If a driver switches between two alt
settings with no endpoints, there is no need to issue a configure endpoint
command, because there is no endpoint information to update.
The only time a configure endpoint command with just the add slot flag set
makes sense is when the driver is updating hub characteristics in the slot
context. However, that code never calls xhci_check_bandwidth, so we
should be safe not issuing a command if only the slot context add flag is
set.

usb_storage: Don't freeze in usb-stor-scan
commit f02fe890ece7d695a5744b20525d45312382e6e4 upstream.
Scanning cannot be run during suspend or hibernation, but if
usb-stor-scan freezes another thread waiting on scanning to
complete may fail to freeze.
However, if usb-stor-scan is left freezable without ever actually
freezing then the freezer will wait on it to exit, and threads
waiting for scanning to finish will no longer be blocked. One
problem with this approach is that usb-stor-scan has a delay to
wait for devices to settle (which is currently the only point where
it can freeze). To work around this we can request that the freezer
send a fake signal when freezing, then use interruptible sleep to
wake the thread early when freezing happens.
To make this happen, the following changes are made to
usb-stor-scan:
* Use set_freezable_with_signal() instead of set_freezable() to
request a fake signal when freezing
* Use wait_event_interruptible_timeout() instead of
wait_event_freezable_timeout() to avoid freezing

USB: xHCI: prevent infinite loop when processing MSE event
commit c2d7b49f42f50d7fc5cbfd195b785a128723fdf4 upstream.
When a xHC host is unable to handle isochronous transfer in the
interval, it reports a Missed Service Error event and skips some tds.
Currently xhci driver handles MSE event in the following ways:
1. When encounter a MSE event, set ep->skip flag, update event ring
dequeue pointer and return.
2. When encounter the next event on this ep, the driver will run the
do-while loop, fetch td from ep's td_list to find the td
corresponding to this event. All tds missed are marked as short
transfer(-EXDEV).
The do-while loop will end in two ways:
1. If the td pointed by the event trb is found;
2. If the ep ring's td_list is empty.
However, if a buggy HW reports some unpredicted event (for example, an
overrun event following a MSE event while the ep ring is actually not
empty), the driver will never find the td, and it will loop until the
td_list is empty.
Unfortunately, the spinlock is dropped when give back a urb in the
do-while loop. During the spinlock released period, the class driver
may still submit urbs and add tds to the td_list. This may cause
disaster, since the td_list will never be empty and the loop never ends,
and the system hangs.
To fix this, count the number of TDs on the ep ring before skipping TDs,
and quit the loop when skipped that number of tds. This guarantees the
do-while loop will end after certain number of cycles, and driver will
not be trapped in an infinite loop.

ext4: fix race in xattr block allocation path
commit 6d6a435190bdf2e04c9465cde5bdc3ac68cf11a4 upstream.
Ceph users reported that when using Ceph on ext4, the filesystem
would often become corrupted, containing inodes with incorrect
i_blocks counters.
I managed to reproduce this with a very hacked-up "streamtest"
binary from the Ceph tree.
Ceph is doing a lot of xattr writes, to out-of-inode blocks.
There is also another thread which does sync_file_range and close,
of the same files. The problem appears to happen due to this race:
sync/flush thread xattr-set thread
----------------- ----------------
do_writepages ext4_xattr_set
ext4_da_writepages ext4_xattr_set_handle
mpage_da_map_blocks ext4_xattr_block_set
set DELALLOC_RESERVE
ext4_new_meta_blocks
ext4_mb_new_blocks
if (!i_delalloc_reserved_flag)
vfs_dq_alloc_block
ext4_get_blocks
down_write(i_data_sem)
set i_delalloc_reserved_flag
...
up_write(i_data_sem)
if (i_delalloc_reserved_flag)
vfs_dq_alloc_block_nofail
In other words, the sync/flush thread pops in and sets
i_delalloc_reserved_flag on the inode, which makes the xattr thread
think that it's in a delalloc path in ext4_new_meta_blocks(),
and add the block for a second time, after already having added
it once in the !i_delalloc_reserved_flag case in ext4_mb_new_blocks
The real problem is that we shouldn't be using the DELALLOC_RESERVED
state flag, and instead we should be passing
EXT4_GET_BLOCKS_DELALLOC_RESERVE down to ext4_map_blocks() instead of
using an inode state flag. We'll fix this for now with using
i_data_sem to prevent this race, but this is really not the right way
to fix things.

Since we're using non-atomic radix tree allocations, we
should be protecting the tree using a mutex and not a
spinlock.
Non-atomic allocations and process context locking is good enough,
as the tree is manipulated only when locks are registered/
unregistered/requested/freed.
The locks themselves are still protected by spinlocks of course,
and mutexes are not involved in the locking/unlocking paths.

iwlagn: do not use interruptible waits
Upstream commit effd4d9aece9184f526e6556786a94d335e38b71.
Since the dawn of its time, iwlwifi has used
interruptible waits to wait for synchronous
commands and firmware loading.
This leads to "interesting" bugs, because it
can't actually handle the interruptions; for
example when a command sending is interrupted
it will assume the command completed fully,
and then leave it pending, which leads to all
kinds of trouble when the command finishes
later.
Since there's no easy way to gracefully deal
with interruptions, fix the driver to not use
interruptible waits.
This at least fixes the error
iwlagn 0000:02:00.0: Error: Response NULL in 'REPLY_SCAN_ABORT_CMD'
I have seen in P2P testing, but it is likely
that there are other errors caused by this.

vfs: show O_CLOEXE bit properly in /proc/<pid>/fdinfo/<fd> files
commit 1117f72ea0217ba0cc19f05adbbd8b9a397f5ab7 upstream.
The CLOEXE bit is magical, and for performance (and semantic) reasons we
don't actually maintain it in the file descriptor itself, but in a
separate bit array. Which means that when we show f_flags, the CLOEXE
status is shown incorrectly: we show the status not as it is now, but as
it was when the file was opened.
Fix that by looking up the bit properly in the 'fdt->close_on_exec' bit
array.
Uli needs this in order to re-implement the pfiles program:
"For normal file descriptors (not sockets) this was the last piece of
information which wasn't available. This is all part of my 'give
Solaris users no reason to not switch' effort. I intend to offer the
code to the util-linux-ng maintainers."

mm: thp: tail page refcounting fix
commit 70b50f94f1644e2aa7cb374819cfd93f3c28d725 upstream.
Michel while working on the working set estimation code, noticed that
calling get_page_unless_zero() on a random pfn_to_page(random_pfn)
wasn't safe, if the pfn ended up being a tail page of a transparent
hugepage under splitting by __split_huge_page_refcount().
He then found the problem could also theoretically materialize with
page_cache_get_speculative() during the speculative radix tree lookups
that uses get_page_unless_zero() in SMP if the radix tree page is freed
and reallocated and get_user_pages is called on it before
page_cache_get_speculative has a chance to call get_page_unless_zero().
So the best way to fix the problem is to keep page_tail->_count zero at
all times. This will guarantee that get_page_unless_zero() can never
succeed on any tail page. page_tail->_mapcount is guaranteed zero and
is unused for all tail pages of a compound page, so we can simply
account the tail page references there and transfer them to
tail_page->_count in __split_huge_page_refcount() (in addition to the
head_page->_mapcount).
While debugging this s/_count/_mapcount/ change I also noticed get_page is
called by direct-io.c on pages returned by get_user_pages. That wasn't
entirely safe because the two atomic_inc in get_page weren't atomic. As
opposed to other get_user_page users like secondary-MMU page fault to
establish the shadow pagetables would never call any superflous get_page
after get_user_page returns. It's safer to make get_page universally safe
for tail pages and to use get_page_foll() within follow_page (inside
get_user_pages()). get_page_foll() is safe to do the refcounting for tail
pages without taking any locks because it is run within PT lock protected
critical sections (PT lock for pte and page_table_lock for
pmd_trans_huge).
The standard get_page() as invoked by direct-io instead will now take
the compound_lock but still only for tail pages. The direct-io paths
are usually I/O bound and the compound_lock is per THP so very
finegrined, so there's no risk of scalability issues with it. A simple
direct-io benchmarks with all lockdep prove locking and spinlock
debugging infrastructure enabled shows identical performance and no
overhead. So it's worth it. Ideally direct-io should stop calling
get_page() on pages returned by get_user_pages(). The spinlock in
get_page() is already optimized away for no-THP builds but doing
get_page() on tail pages returned by GUP is generally a rare operation
and usually only run in I/O paths.
This new refcounting on page_tail->_mapcount in addition to avoiding new
RCU critical sections will also allow the working set estimation code to
work without any further complexity associated to the tail page
refcounting with THP.

net: xen-netback: correctly restart Tx after a VM restore/migrate
[ Upstream commit d0e5d83284dac15c015bb48115b6780f5a6413cd ]
If a VM is saved and restored (or migrated) the netback driver will no
longer process any Tx packets from the frontend. xenvif_up() does not
schedule the processing of any pending Tx requests from the front end
because the carrier is off. Without this initial kick the frontend
just adds Tx requests to the ring without raising an event (until the
ring is full).
This was caused by 47103041e91794acdbc6165da0ae288d844c820b (net:
xen-netback: convert to hw_features) which reordered the calls to
xenvif_up() and netif_carrier_on() in xenvif_connect().

make PACKET_STATISTICS getsockopt report consistently between ring and non-ring
[ Upstream commit 7091fbd82cd5686444ffe9935ed6a8190101fe9d ]
This is a minor change.
Up until kernel 2.6.32, getsockopt(fd, SOL_PACKET, PACKET_STATISTICS,
...) would return total and dropped packets since its last invocation. The
introduction of socket queue overflow reporting [1] changed drop
rate calculation in the normal packet socket path, but not when using a
packet ring. As a result, the getsockopt now returns different statistics
depending on the reception method used. With a ring, it still returns the
count since the last call, as counts are incremented in tpacket_rcv and
reset in getsockopt. Without a ring, it returns 0 if no drops occurred
since the last getsockopt and the total drops over the lifespan of
the socket otherwise. The culprit is this line in packet_rcv, executed
on a drop:
drop_n_acct:
po->stats.tp_drops = atomic_inc_return(&sk->sk_drops);
As it shows, the new drop number it taken from the socket drop counter,
which is not reset at getsockopt. I put together a small example
that demonstrates the issue [2]. It runs for 10 seconds and overflows
the queue/ring on every odd second. The reported drop rates are:
ring: 16, 0, 16, 0, 16, ...
non-ring: 0, 15, 0, 30, 0, 46, 0, 60, 0 , 74.
Note how the even ring counts monotonically increase. Because the
getsockopt adds tp_drops to tp_packets, total counts are similarly
reported cumulatively. Long story short, reinstating the original code, as
the below patch does, fixes the issue at the cost of additional per-packet
cycles. Another solution that does not introduce per-packet overhead
is be to keep the current data path, record the value of sk_drops at
getsockopt() at call N in a new field in struct packetsock and subtract
that when reporting at call N+1. I'll be happy to code that, instead,
it's just more messy.

tcp: properly update lost_cnt_hint during shifting
[ Upstream commit 1e5289e121372a3494402b1b131b41bfe1cf9b7f ]
lost_skb_hint is used by tcp_mark_head_lost() to mark the first unhandled skb.
lost_cnt_hint is the number of packets or sacked packets before the lost_skb_hint;
When shifting a skb that is before the lost_skb_hint, if tcp_is_fack() is ture,
the skb has already been counted in the lost_cnt_hint; if tcp_is_fack() is false,
tcp_sacktag_one() will increase the lost_cnt_hint. So tcp_shifted_skb() does not
need to adjust the lost_cnt_hint by itself. When shifting a skb that is equal to
lost_skb_hint, the shifted packets will not be counted by tcp_mark_head_lost().
So tcp_shifted_skb() should adjust the lost_cnt_hint even tcp_is_fack(tp) is true.

bonding: use local function pointer of bond->recv_probe in bond_handle_frame
[ Upstream commit 4d97480b1806e883eb1c7889d4e7a87e936e06d9 ]
The bond->recv_probe is called in bond_handle_frame() when
a packet is received, but bond_close() sets it to NULL. So,
a panic occurs when both functions work in parallel.
Why this happen:
After null pointer check of bond->recv_probe, an sk_buff is
duplicated and bond->recv_probe is called in bond_handle_frame.
So, a panic occurs when bond_close() is called between the
check and call of bond->recv_probe.
Patch:
This patch uses a local function pointer of bond->recv_probe
in bond_handle_frame(). So, it can avoid the null pointer
dereference.

jsm: remove buggy write queue
commit 9d898966c4a07e4a5092215b5a2829d0ef02baa2 upstream.
jsm uses a write queue that copies from uart_core circular buffer. This
copying however has some bugs, like not wrapping the head counter. Since
this write queue is also a circular buffer, the consumer function is
ready to use the uart_core circular buffer directly.
This buggy copying function was making some bytes be dropped when
transmitting to a raw tty, doing something like this.

1. Luke Macken triggered WARN_ON(!(group_stop & GROUP_STOP_SIGMASK))
in do_signal_stop().
This is because do_signal_stop() clears GROUP_STOP_SIGMASK part
unconditionally but doesn't update it if task_is_stopped().
2. Looking at this problem I noticed that WARN_ON_ONCE(!ptrace) is
not right, a stopped-but-resumed tracee can clone the untraced
thread in the SIGNAL_STOP_STOPPED group, the new thread can start
another group-stop.
Remove this warning, we need more fixes to make it true.

vfs pathname lookup: Add LOOKUP_AUTOMOUNT flag
Since we've now turned around and made LOOKUP_FOLLOW *not* force an
automount, we want to add the ability to force an automount event on
lookup even if we don't happen to have one of the other flags that force
it implicitly (LOOKUP_OPEN, LOOKUP_DIRECTORY, LOOKUP_PARENT..)
Most cases will never want to use this, since you'd normally want to
delay automounting as long as possible, which usually implies
LOOKUP_OPEN (when we open a file or directory, we really cannot avoid
the automount any more).
But Trond argued sufficiently forcefully that at a minimum bind mounting
a file and quotactl will want to force the automount lookup. Some other
cases (like nfs_follow_remote_path()) could use it too, although
LOOKUP_DIRECTORY would work there as well.
This commit just adds the flag and logic, no users yet, though. It also
doesn't actually touch the LOOKUP_NO_AUTOMOUNT flag that is related, and
was made irrelevant by the same change that made us not follow on
LOOKUP_FOLLOW.

vfs: automount should ignore LOOKUP_FOLLOW
commit 0ec26fd0698285b31248e34bf1abb022c00f23d6 upstream.
Prior to 2.6.38 automount would not trigger on either stat(2) or
lstat(2) on the automount point.
After 2.6.38, with the introduction of the ->d_automount()
infrastructure, stat(2) and others would start triggering automount
while lstat(2), etc. still would not. This is a regression and a
userspace ABI change.
Problem originally reported here:
http://thread.gmane.org/gmane.linux.kernel.autofs/6098
It appears that there was an attempt at fixing various userspace tools
to not trigger the automount. But since the stat system call is
rather common it is impossible to "fix" all userspace.
This patch reverts the original behavior, which is to not trigger on
stat(2) and other symlink following syscalls.
[ It's not really clear what the right behavior is. Apparently Solaris
does the "automount on stat, leave alone on lstat". And some programs
can get unhappy when "stat+open+fstat" ends up giving a different
result from the fstat than from the initial stat.
But the change in 2.6.38 resulted in problems for some people, so
we're going back to old behavior. Maybe we can re-visit this
discussion at some future date - Linus ]

readlinkat: ensure we return ENOENT for the empty pathname for normal lookups

Since the commit below which added O_PATH support to the *at() calls, the

from ENOENT to EINVAL:

readlinkat(), fchownat() and fstatat() with empty relative pathnames
This is both unexpected for userspace and makes readlink/readlinkat
inconsistant with all other interfaces; and inconsistant with our stated
return for these pathnames.
As the readlinkat call does not have a flags parameter we cannot use the
AT_EMPTY_PATH approach used in the other calls. Therefore expose whether
the original path is infact entry via a new user_path_at_empty() path
lookup function. Use this to determine whether to default to EINVAL or
ENOENT for failures.

ALSA: hda - Fix ADC input-amp handling for Cx20549 codec
commit 6b45214277bec2193ad3ccb8d7aa6100b5a0f1a9 upstream.
It seems that Conexant CX20549 chip handle only a single input-amp even
though the audio-input widget has multiple sources. This has been never
clear, and I implemented in the current way based on the debug information
I got at the early time -- the device reacts individual input-amp values
for different sources. This is true for another Conexant codec, but it's
not applied to CX20549 actually.
This patch changes the auto-parser code to handle a single input-amp
per audio-in widget for CX20549. After applying this, you'll see only a
single "Capture" volume control instead of separate "Mic" or "Line"
captures when the device is set up to use a single ADC.
We haven't tested 20551 and 20561 codecs yet. If these show the similar
behavior like 20549, they need to set spec->single_adc_amp=1, too.

mm: avoid null pointer access in vm_struct via /proc/vmallocinfo
commit f5252e009d5b87071a919221e4f6624184005368 upstream.
The /proc/vmallocinfo shows information about vmalloc allocations in
vmlist that is a linklist of vm_struct. It, however, may access pages
field of vm_struct where a page was not allocated. This results in a null
pointer access and leads to a kernel panic.
Why this happens: In __vmalloc_node_range() called from vmalloc(), newly
allocated vm_struct is added to vmlist at __get_vm_area_node() and then,
some fields of vm_struct such as nr_pages and pages are set at
__vmalloc_area_node(). In other words, it is added to vmlist before it is
fully initialized. At the same time, when the /proc/vmallocinfo is read,
it accesses the pages field of vm_struct according to the nr_pages field
at show_numa_info(). Thus, a null pointer access happens.
The patch adds the newly allocated vm_struct to the vmlist *after* it is
fully initialized. So, it can avoid accessing the pages field with
unallocated page when show_numa_info() is called.

ARM: mach-ux500: unlock I&D l2x0 caches before init
commit 1bf6d2c1bb23533af6930581cc39b74685bc29de upstream.
Apparently U8500 U-Boot versions may leave the l2x0 locked down
before executing the kernel. Make sure we unlock it before we
initialize the l2x0. This fixes a performance problem reported
by Jan Rinze.
The l2x0 core has been modified to unlock the l2x0 by default,
but it will not touch the locking registers if the l2x0 was
already enabled, as on the ux500, so we need this quirk to
make sure it is properly turned off.

plat-mxc: iomux-v3.h: implicitly enable pull-up/down when that's desired
commit 6571534b600b8ca1936ff5630b9e0947f21faf16 upstream.
To configure pads during the initialisation a set of special constants
is used, e.g.
#define MX25_PAD_FEC_MDIO__FEC_MDIO IOMUX_PAD(0x3c4, 0x1cc, 0x10, 0, 0, PAD_CTL_HYS | PAD_CTL_PUS_22K_UP)
The problem is that no pull-up/down is getting activated unless both
PAD_CTL_PUE (pull-up enable) and PAD_CTL_PKE (pull/keeper module
enable) set. This is clearly stated in the i.MX25 datasheet and is
confirmed by the measurements on hardware. This leads to some rather
hard to understand bugs such as misdetecting an absent ethernet PHY (a
real bug i had), unstable data transfer etc. This might affect mx25,
mx35, mx50, mx51 and mx53 SoCs.
It's reasonable to expect that if the pullup value is specified, the
intention was to have it actually active, so we implicitly add the
needed bits.

fb: avoid possible deadlock caused by fb_set_suspend
commit 9e769ff3f585db8f978f9113be83d36c7e3965dd upstream.
A lock ordering issue can cause deadlocks: in framebuffer/console code,
all needed struct fb_info locks are taken before acquire_console_sem(),
in places which need to take console semaphore.
But fb_set_suspend is always called with console semaphore held, and
inside it we call lock_fb_info which gets the fb_info lock, inverse
locking order of what the rest of the code does. This causes a real
deadlock issue, when we write to state fb sysfs attribute (which calls
fb_set_suspend) while a framebuffer is being unregistered by
remove_conflicting_framebuffers, as can be shown by following show
blocked state trace on a test program which loads i915 and runs another
forked processes writing to state attribute:

fb-test2 which reproduces above is available on kernel.org bug #26232.
To solve this issue, avoid calling lock_fb_info inside fb_set_suspend,
and move it out to where needed (callers of fb_set_suspend must call
lock_fb_info before if needed). So far, the only place which needs to
call lock_fb_info is store_fbstate, all other places which calls
fb_set_suspend are suspend/resume hooks that should not need the lock as
they should be run only when processes are already frozen in
suspend/resume.

carminefb: Fix module parameters permissions
commit c84c14224bbca6ec60d5851fcc87be0e34df2f44 upstream.
The third parameter of module_param is supposed to be an octal value.
The missing leading "0" causes the following:
$ ls -l /sys/module/carminefb/parameters/

-rw-rwxr-- 1 root root 4096 Jul 8 08:55 fb_displays
-rw-rwxr-- 1 root root 4096 Jul 8 08:55 fb_mode
-rw-rwxr-- 1 root root 4096 Jul 8 08:55 fb_mode_str
After fixing the perm parameter, we get the expected:
$ ls -l /sys/module/carminefb/parameters/
total 0
-r--r--r-- 1 root root 4096 Jul 8 08:56 fb_displays

memory leak with RCU_TABLE_FREE
commit e73b7fffe487c315fd1a4fa22282e3362b440a06 upstream.
The rcu page table free code uses a couple of bits in the page table
pointer passed to tlb_remove_table to discern the different page table

user per registers vs. ptrace single stepping
commit a45aff5285871bf7be1781d9462d3fdbb6c913f9 upstream.
git commit 5e9a2692 "[S390] ptrace cleanup" introduced a regression
for the case when both a user PER set (e.g. a storage alteration trace) and
PTRACE_SINGLESTEP are active. The new code will overrule the user PER set
with a instruction-fetch PER set over the whole address space for ptrace
single stepping. The inferior process will be stopped after each instruction
with an instruction fetch event. Any other events that may have occurred
concurrently are not reported (e.g. storage alteration event) because the
control bits for them are not set. The solution is to merge the PER control
bits of the user PER set with the PER_EVENT_IFETCH control bit for
PTRACE_SINGLESTEP.

For the !HAVE_ATOMIC_IOMAP case the stub functions did not call

actually being atomic, otherwise it can deadlock with it's own
pagefault handler in the gtt pwrite fastpath.
This is exercised by gem_mmap_gtt from the intel-gpu-toosl gem

nfsd4: fix open downgrade, again
commit 3d02fa29dec920c597dd7b7db608a4bc71f088ce upstream.
Yet another open-management regression:
- nfs4_file_downgrade() doesn't remove the BOTH access bit on
downgrade, so the server's idea of the stateid's access gets
out of sync with the client's. If we want to keep an O_RDWR
open in this case, we should do that in the file_put_access
logic rather than here.
- We forgot to convert v4 access to an open mode here.
This logic has proven too hard to get right. In the future we may
consider:
- reexamining the lock/openowner relationship (locks probably
don't really need to take their own references here).
- adding open upgrade/downgrade support to the vfs.
- removing the atomic operations. They're redundant as long as
this is all under some other lock.
Also, maybe some kind of additional static checking would help catch
O_/NFS4_SHARE_ACCESS confusion.

nfsd4: permit read opens of executable-only files
commit a043226bc140a2c1dde162246d68a67e5043e6b2 upstream.
A client that wants to execute a file must be able to read it. Read
opens over nfs are therefore implicitly allowed for executable files
even when those files are not readable.
NFSv2/v3 get this right by using a passed-in NFSD_MAY_OWNER_OVERRIDE on
read requests, but NFSv4 has gotten this wrong ever since
dc730e173785e29b297aa605786c94adaffe2544 "nfsd4: fix owner-override on
open", when we realized that the file owner shouldn't override
permissions on non-reclaim NFSv4 opens.
So we can't use NFSD_MAY_OWNER_OVERRIDE to tell nfsd_permission to allow
reads of executable files.
So, do the same thing we do whenever we encounter another weird NFS
permission nit: define yet another NFSD_MAY_* flag.
The industry's future standardization on 128-bit processors will be
motivated primarily by the need for integers with enough bits for all
the NFSD_MAY_* flags.

nfs: don't try to migrate pages with active requests
commit 2da956523526e440ef4f4dd174e26f5ac06fe011 upstream.
nfs_find_and_lock_request will take a reference to the nfs_page and
will then put it if the req is already locked. It's possible though
that the reference will be the last one. That put then can kick off
a whole series of reference puts:
nfs_page
nfs_open_context
dentry
inode
If the inode ends up being deleted, then the VFS will call
truncate_inode_pages. That function will try to take the page lock, but
it was already locked when migrate_page was called. The code
deadlocks.
Fix this by simply refusing the migration request if PagePrivate is
already set, indicating that the page is already associated with an
active read or write request.
We've had a customer test a backported version of this patch and
the preliminary results seem good.

tracing: Fix returning of duplicate data after EOF in trace_pipe_raw
commit 436fc280261dcfce5af38f08b89287750dc91cd2 upstream.
The trace_pipe_raw handler holds a cached page from the time the file
is opened to the time it is closed. The cached page is used to handle
the case of the user space buffer being smaller than what was read from
the ring buffer. The left over buffer is held in the cache so that the
next read will continue where the data left off.
After EOF is returned (no more data in the buffer), the index of
the cached page is set to zero. If a user app reads the page again
after EOF, the check in the buffer will see that the cached page
is less than page size and will return the cached page again. This
will cause reading the trace_pipe_raw again after EOF to return
duplicate data, making the output look like the time went backwards
but instead data is just repeated.
The fix is to not reset the index right after all data is read
from the cache, but to reset it after all data is read and more
data exists in the ring buffer.

md/raid5: fix bug that could result in reads from a failed device.
commit 355840e7a7e56bb2834fd3b0da64da5465f8aeaa upstream.
This bug was introduced in 415e72d034c50520ddb7ff79e7d1792c1306f0c9
which was in 2.6.36.
There is a small window of time between when a device fails and when
it is removed from the array. During this time we might still read
from it, but we won't write to it - so it is possible that we could
read stale data.
We didn't need the test of 'Faulty' before because the test on
In_sync is sufficient. Since we started allowing reads from the early
part of non-In_sync devices we need a test on Faulty too.
This is suitable for any kernel from 2.6.36 onwards, though the patch
might need a bit of tweaking in 3.0 and earlier.

wl12xx: fix forced passive scans
commit 6cd9d21a0c1e2648c07c32c66bb25795ad3208aa upstream.
We were using incorrect max and min dwell times during forced passive
scans because we were still using the active scan states to scan
(passively) the channels that were not marked as passive.
Instead of doing passive scans in active states, we now skip active
states and scan for all channels in passive states.

net: hold sock reference while processing tx timestamps
commit da92b194cc36b5dc1fbd85206aeeffd80bee0c39 upstream.
The pair of functions,
* skb_clone_tx_timestamp()
* skb_complete_tx_timestamp()
were designed to allow timestamping in PHY devices. The first
function, called during the MAC driver's hard_xmit method, identifies
PTP protocol packets, clones them, and gives them to the PHY device
driver. The PHY driver may hold onto the packet and deliver it at a
later time using the second function, which adds the packet to the
socket's error queue.
As pointed out by Johannes, nothing prevents the socket from
disappearing while the cloned packet is sitting in the PHY driver
awaiting a timestamp. This patch fixes the issue by taking a reference
on the socket for each such packet. In addition, the comments
regarding the usage of these function are expanded to highlight the
rule that PHY drivers must use skb_complete_tx_timestamp() to release
the packet, in order to release the socket reference, too.
These functions first appeared in v2.6.36.

rtnetlink: Add missing manual netlink notification in dev_change_net_namespaces
commit d2237d35748e7f448a9c2d9dc6a85ef637466e24 upstream.
Renato Westphal noticed that since commit a2835763e130c343ace5320c20d33c281e7097b7
"rtnetlink: handle rtnl_link netlink notifications manually" was merged
we no longer send a netlink message when a networking device is moved
from one network namespace to another.
Fix this by adding the missing manual notification in dev_change_net_namespaces.
Since all network devices that are processed by dev_change_net_namspaces are
in the initialized state the complicated tests that guard the manual
rtmsg_ifinfo calls in rollback_registered and register_netdevice are
unnecessary and we can just perform a plain notification.

ata_piix: make DVD Drive recognisable on systems with Intel Sandybridge chipsets(v2)
commit 5e5a4f5d5a08c9c504fe956391ac3dae2c66556d upstream.
This quirk patch fixes one kind of bug inside some Intel Sandybridge
chipsets, see reports from
https://bugzilla.kernel.org/show_bug.cgi?id=40592.
Many guys also have reported the problem before:
https://bugs.launchpad.net/bugs/737388
https://bugs.launchpad.net/bugs/794642
https://bugs.launchpad.net/bugs/782389
......
With help from Tejun, the problem is found to be caused by 32bit PIO
mode, so introduce the quirk patch to disable 32bit PIO on SATA piix
for some Sandybridge CPT chipsets.
Seth also tested the patch on all five affected chipsets
(pci device ID: 0x1c00, 0x1c01, 0x1d00, 0x1e00, 0x1e01), and found
the patch does fix the problem.

nfs: don't redirty inode when ncommit == 0 in nfs_commit_unstable_pages
commit 3236c3e1adc0c7ec83eaff1de2d06746b7c5bb28 upstream.
commit 420e3646 allowed the kernel to reduce the number of unnecessary
commit calls by skipping the commit when there are a large number of
outstanding pages.
However, the current test in nfs_commit_unstable_pages does not handle
the edge condition properly. When ncommit == 0, then that means that the
kernel doesn't need to do anything more for the inode. The current test
though in the WB_SYNC_NONE case will return true, and the inode will end
up being marked dirty. Once that happens the inode will never be clean
until there's a WB_SYNC_ALL flush.
Fix this by immediately returning from nfs_commit_unstable_pages when
ncommit == 0.
Mike noticed this problem initially in RHEL5 (2.6.18-based kernel) which
has a backported version of 420e3646. The inode cache there was growing
very large. The inode cache was unable to be shrunk since the inodes
were all marked dirty. Calling sync() would essentially "fix" the
problem -- the WB_SYNC_ALL flush would result in the inodes all being
marked clean.
What I'm not clear on is how big a problem this is in mainline kernels
as the writeback code there is very different. Either way, it seems
incorrect to re-mark the inode dirty in this case.

commit 59b7c05fffba030e5d9e72324691e2f99aa69b79 upstream.
This reverts commit b80c3cb628f0ebc241b02e38dd028969fb8026a2.
The reverted commit was rendered obsolete by a VFS fix: commit
5547e8aac6f71505d621a612de2fca0dd988b439 (writeback: Update dirty flags in
two steps). We now no longer need to worry about writeback_single_inode()
missing our marking the inode for COMMIT in 'do_writepages()' call.
Reverting this patch, fixes a performance regression in which the inode
would continuously get queued to the dirty list, causing the writeback
code to unnecessarily try to send a COMMIT.

commit bee460be8c691c544e84ed678280ace6153104c6 upstream.
The min_brightness value of the sabi_config is incorrectly used in brightness
calculations. For the config where min_brightness = 1 and max_brightness = 8,
the user visible range should be 0 to 7 with hardware being set in the range
of 1 to 8. What is actually happening is that the user visible range is 0 to
8 with hardware being set in the range of -1 to 7.
This patch fixes the above issue as well as a miscalculation that would occur

caif: Fix BUG() with network namespaces
commit 08613e4626c06ca408fc55071f6aedee36986a87 upstream.
The caif code will register its own pernet_operations, and then register
a netdevice_notifier. Each time the netdevice_notifier is triggered,
it'll do some stuff... including a lookup of its own pernet stuff with
net_generic().
If the net_generic() call ever returns NULL, the caif code will BUG().
That doesn't seem *so* unreasonable, I suppose — it does seem like it
should never happen.
However, it *does* happen. When we clone a network namespace,
setup_net() runs through all the pernet_operations one at a time. It
gets to loopback before it gets to caif. And loopback_net_init()
registers a netdevice... while caif hasn't been initialised. So the caif
netdevice notifier triggers, and immediately goes BUG().
We could imagine a complex and overengineered solution to this generic
class of problems, but this patch takes the simple approach. It just
makes caif_device_notify() *not* go looking for its pernet data
structures if the device it's being notified about isn't a caif device
in the first place.

With Xen changeset 23428 "libxl: Add 'e820_host' option to config file"
the E820 as seen from the host can now be passed into the guest.
This means that a PV guest can now:
- Use the correct PCI I/O gap. Before these patches, Linux guest would
boot up and would tell:
[ 0.000000] Allocating PCI resources starting at 40000000 (gap: 40000000:c0000000)
while in actuality the PCI I/O gap should have been:
[ 0.000000] Allocating PCI resources starting at b0000000 (gap: b0000000:4c000000)
- The PV domain with PCI devices was limited to 3GB. It now can be booted
with 4GB, 8GB, or whatever number you want. The PCI devices will now _not_ conflict
with System RAM. Meaning the drivers can load.

ath9k_hw: Fix magnitude/phase coeff correction
commit e9c10469cf3c71bc1c6b0f01319161e277d6ac9b upstream.
Do the magnitude/phase coeff correction only if the outlier
is detected. Updating wrong magnitude/phase coeff factor
impacts not only tx gain setting but also leads to poor
performance in congested networks. In the clear environment
the impact is very minimal because the outlier happens
very rarely according to the past experiment. It occured
less than once every 1000 calibrations.

commit 2394d67e446bf616a0885167d5f0d397bdacfdfc upstream.
The new runtime PM code has shown that many webcams suffer
from a race condition that may crash them upon resume.
Runtime PM is especially prone to show the problem because
it retains power to the cameras at all times. However
system suspension may also crash the devices and retain
power to the devices.
The only way to solve this problem without races is in
usbcore with the RESET_RESUME quirk.

USB: Fix runtime wakeup on OHCI
commit a8b43c00ef06aec49b9fe0a5bad8a6a320e4d27b upstream.
At least some OHCI hardware (such as the MCP89) fails to flag any change
in the host status register or the port status registers when receiving
a remote wakeup while in D3 state. This results in the controller being
resumed but no device state change being noticed, at which point the
controller is put back to sleep again. Since there doesn't seem to be any
reliable way to identify the state change, just unconditionally resume the
hub. It'll be put back to sleep in the near future anyway if there are no
active devices attached to it.

leds: turn the blink_timer off before starting to blink
commit 488bc35bf40df89d37486c1826b178a2fba36ce7 upstream.
Depending on the implementation of the hardware blinking function in
blink_set(), the led can support hardware blinking for some values of
delay_on and delay_off and fall-back to software blinking for some other
values.
Turning off the blink_timer unconditionally before starting to blink
make sure that a sequence like:
OFF
hardware blinking
software blinking
hardware blinking
does not leave the software blinking timer active.

epoll: fix spurious lockdep warnings
commit d8805e633e054c816c47cb6e727c81f156d9253d upstream.
epoll can acquire recursively acquire ep->mtx on multiple "struct
eventpoll"s at once in the case where one epoll fd is monitoring another
epoll fd. This is perfectly OK, since we're careful about the lock
ordering, but it causes spurious lockdep warnings. Annotate the recursion
using mutex_lock_nested, and add a comment explaining the nesting rules
for good measure.
Recent versions of systemd are triggering this, and it can also be
demonstrated with the following trivial test program:
--------------------8<--------------------
int main(void) {
int e1, e2;
struct epoll_event evt = {
.events = EPOLLIN
};
e1 = epoll_create1(0);
e2 = epoll_create1(0);
epoll_ctl(e1, EPOLL_CTL_ADD, e2, &evt);
return 0;
}

x86: Fix compilation bug in kprobes' twobyte_is_boostable
commit 315eb8a2a1b7f335d40ceeeb11b9e067475eb881 upstream.
When compiling an i386_defconfig kernel with gcc-4.6.1-9.fc15.i686, I
noticed a warning about the asm operand for test_bit in kprobes'
can_boost. I discovered that this caused only the first long of
twobyte_is_boostable[] to be output.
Jakub filed and fixed gcc PR50571 to correct the warning and this output
issue. But to solve it for less current gcc, we can make kprobes'
twobyte_is_boostable[] non-const, and it won't be optimized out.

x86: uv2: Workaround for UV2 Hub bug (system global address format)
commit 6a469e4665bc158599de55d64388861d0a9f10f4 upstream.
This is a workaround for a UV2 hub bug that affects the format of system
global addresses.
The GRU API for UV2 was inadvertently broken by a hardware change. The
format of the physical address used for TLB dropins and for addresses used
with instructions running in unmapped mode has changed. This change was
not documented and became apparent only when diags failed running on
system simulators.
For UV1, TLB and GRU instruction physical addresses are identical to
socket physical addresses (although high NASID bits must be OR'ed into the
address).
For UV2, socket physical addresses need to be converted. The NODE portion
of the physical address needs to be shifted so that the low bit is in bit
39 or bit 40, depending on an MMR value.
It is not yet clear if this bug will be fixed in a silicon respin. If it
is fixed, the hub revision will be incremented & the workaround disabled.

target: Fix REPORT TARGET PORT GROUPS handling with small allocation length
commit 6b20fa9aaf0c2f69ee6f9648e20ab2be0206705e upstream.
This patch fixes a bug with the handling of REPORT TARGET PORT GROUPS
containing a smaller allocation length than the payload requires causing
memory writes beyond the end of the buffer. This patch checks for the
minimum 4 byte length for the response payload length, and also checks
upon each loop of T10_ALUA(su_dev)->tg_pt_gps_list to ensure the Target
port group and Target port descriptor list is able to fit into the
remaining allocation length.
If the response payload exceeds the allocation length length, then rd_len
is still increments to indicate to the initiator that the payload has
been truncated.

The purpose of this patch is to remove a section of "bad" code that
assigns the last DAC to ports E or F in order to support notebooks
with docking in earlier days, around ALSA 1.0.19 - 21. This is not
necessary now and actually breaks some configurations that use these
ports as other devices. This have been tested on several different

ipr: Always initiate hard reset in kdump kernel
commit 5d7c20b7fa5c6ca19e871b4050e321c99d32bd43 upstream.
During kdump testing I noticed timeouts when initialising each IPR
adapter. While the driver has logic to detect an adapter in an
indeterminate state, it wasn't triggering and each adapter went
through a 5 minute timeout before finally going operational.
Some analysis showed the needs_hard_reset flag wasn't getting set.
We can check the reset_devices kernel parameter which is set by
kdump and force a full reset. This fixes the problem.

megaraid_sas: Fix instance access in megasas_reset_timer
commit f575c5d3ebdca3b0482847d8fcba971767754a9e upstream.
The following patch for megaraid_sas will fix a potential bad pointer access
in megasas_reset_timer(), when a MegaRAID 9265/9285 or 9360/9380 gets a
timeout. megasas_build_io_fusion() sets SCp.ptr to be a struct
megasas_cmd_fusion *, but then megasas_reset_timer() was casting SCp.ptr to be
a struct megasas_cmd *, then trying to access cmd->instance, which is invalid.
Just loading instance from scmd->device->host->hostdata in
megasas_reset_timer() fixes the issue.

PCI quirk: mmc: Always check for lower base frequency quirk for Ricoh 1180:e823
commit 3e309cdf07c930f29a4e0f233e47d399bea34c68 upstream.
Commit 15bed0f2f added a quirk for the e823 Ricoh card reader to lower the
base frequency. However, the quirk first checks to see if the proprietary
MMC controller is disabled, and returns if so. On some devices, such as the
Lenovo X220, the MMC controller is already disabled by firmware it seems,
but the frequency change is still needed so sdhci-pci can talk to the cards.
Since the MMC controller is disabled, the frequency fixup was never being run
on these machines.
This moves the e823 check above the MMC controller check so that it always
gets run.

mmc: core: Fix hangs related to insert/remove of cards
commit 7f7e4129c23f0419257184dff6fec89d2d5a8964 upstream.
During a rescan operation mmc_attach(sd|mmc|sdio) functions are
called. The error handling in these function can trigger a detach
of the bus, which also meant a power off. This is not notified by
the rescan operation which then continues to the next attach function.
If a power off has been done, the framework must never send any
new commands to the host driver, without first doing a new power up.
This will most likely trigger any host driver to hang.
Moving power off out of detach and instead handle power off
separately when it is actually needed, solves the issue.

previously and use that to determine whether we return the previous

drm/i915/panel: Always record the backlight level again (but cleverly)
commit f52c619a590fa75276c07dfcaf380dee53e4ea4c upstream.
The commit 47356eb67285014527a5ab87543ba1fae3d1e10a introduced a
mechanism to record the backlight level only at disabling time, but it
also introduced a regression. Since intel_lvds_enable() may be called
without disabling (e.g. intel_lvds_commit() calls it unconditionally),
the backlight gets back to the last recorded value. For example, this
happens when you dim the backlight, close the lid and open the lid,
then the backlight suddenly goes to the brightest.
This patch fixes the bug by recording the backlight level always
when changed via intel_panel_set_backlight(). And,
intel_panel_{enable|disable}_backlight() call the internal function not
to update the recorded level wrongly.

xHCI: AMD isoc link TRB chain bit quirk
commit 7e393a834b41001174a8fb3ae3bc23a749467760 upstream.
Setting the chain (CH) bit in the link TRB of isochronous transfer rings
is required by AMD 0.96 xHCI host controller to successfully transverse
multi-TRB TD that span through different memory segments.
When a Missed Service Error event occurs, if the chain bit is not set in
the link TRB and the host skips TDs which just across a link TRB, the
host may falsely recognize the link TRB as a normal TRB. You can see
this may cause big trouble - the host does not jump to the right address
which is pointed by the link TRB, but continue fetching the memory which
is after the link TRB address, which may not even belong to the host,
and the result cannot be predicted.
This causes some big problems. Without the former patch I sent: "xHCI:
prevent infinite loop when processing MSE event", the system may hang.
With that patch applied, system does not hang, but the host still access
wrong memory address and isoc transfer will fail. With this patch,
isochronous transfer works as expected.
This patch should be applied to kernels as old as 2.6.36, which was when
the first isochronous support was added for the xHCI host controller.

There are 2 situations wherein the xhci_ring* might not get freed:
- When xhci_ring_alloc() -> xhci_segment_alloc() returns NULL and
we goto the fail: label in xhci_ring_alloc. In this case, the ring
will not get kfreed.
- When the num_segs argument to xhci_ring_alloc is passed as 0 and
we try to free the rung after that.
( This doesn't really happen as of now in the code but we seem to
be entertaining num_segs=0 in xhci_ring_alloc )
This should be backported to kernels as old as 2.6.31.

EHCI: workaround for MosChip controller bug
commit 68aa95d5d4de31c9348c1628ffa85c805305ebc5 upstream.
This patch (as1489) works around a hardware bug in MosChip EHCI
controllers. Evidently when one of these controllers increments the
frame-index register, it changes the three low-order bits (the
microframe counter) before changing the higher order bits (the frame
counter). If the register is read at just the wrong time, the value
obtained is too low by 8.
When the appropriate quirk flag is set, we work around this problem by
reading the frame-index register a second time if the first value's
three low-order bits are all 0. This gives the hardware a chance to
finish updating the register, yielding the correct value.

staging: quatech_usb2: Potential lost wakeup scenario in TIOCMIWAIT
commit e8df1674d383d2ecc6efa8d7dba74c03aafdfdd7 upstream.
If the usermode app does an ioctl over this serial device by
using TIOCMIWAIT, then the code will wait by setting the current
task state to TASK_INTERRUPTIBLE and then calling schedule().
This will be woken up by the qt2_process_modem_status on URB
completion when the port_extra->shadowMSR is set to the new
modem status.
However, this could result in a lost wakeup scenario due to a race
in the logic in the qt2_ioctl(TIOCMIWAIT) loop and the URB completion
for new modem status in qt2_process_modem_status.
Due to this, the usermode app's task will continue to sleep despite a
change in the modem status.

The serqt_usb2 driver will not work properly with the ssu100 device

ssu100 driver in mainline so there is no need to have it claimed by
serqt_usb2.

USB: for usb_autopm_get_interface_async -EINPROGRESS is not an error
commit c5a48592d874ddef8c7880311581eccf0eb30c3b upstream.
A return value of -EINPROGRESS from pm_runtime_get indicates that
the device is already resuming due to a previous call. Internally,
usb_autopm_get_interface_async doesn't treat this as an error and
increments the usage count, but passes the error status along
to the caller. The logical assumption of the caller is that
any negative return value reflects the device not resuming
and the pm_usage_cnt not being incremented. Since the usage count
is being incremented and the device is resuming, return success (0)
instead.

TTY: pty, release tty in all ptmx_open fail paths
commit 1177c0efc04d032644895b8d757f55b433912596 upstream.
Mistakenly, commit 64ba3dc3143d (tty: never hold BTM while getting
tty_mutex) switched one fail path in ptmx_open to not free the newly
allocated tty.
Fix that by jumping to the appropriate place. And rename the labels so
that it's clear what is going on there.

TTY: make tty_add_file non-failing
commit fa90e1c935472281de314e6d7c9a37db9cbc2e4e upstream.
If tty_add_file fails at the point it is now, we have to revert all
the changes we did to the tty. It means either decrease all refcounts
if this was a tty reopen or delete the tty if it was newly allocated.
There was a try to fix this in v3.0-rc2 using tty_release in 0259894c7
(TTY: fix fail path in tty_open). But instead it introduced a NULL
dereference. It's because tty_release dereferences
filp->private_data, but that one is set even in our tty_add_file. And
when tty_add_file fails, it's still NULL/garbage. Hence tty_release
cannot be called there.
To circumvent the original leak (and the current NULL deref) we split
tty_add_file into two functions, making the latter non-failing. In
that case we may do the former early in open, where handling failures
is easy. The latter stays as it is now. So there is no change in
functionality.
The original bug (leak) was introduced by f573bd176 (tty: Remove
__GFP_NOFAIL from tty_add_file()). Thanks Dan for reporting this.
Later, we may split tty_release into more functions and call only some
of them in this fail path instead. (If at all possible.)

TTY: drop driver reference in tty_open fail path
commit c290f8358acaeffd8e0c551ddcc24d1206143376 upstream.
When tty_driver_lookup_tty fails in tty_open, we forget to drop a
reference to the tty driver. This was added by commit 4a2b5fddd5 (Move
tty lookup/reopen to caller).
Fix that by adding tty_driver_kref_put to the fail path.
I will refactor the code later. This is for the ease of backporting to
stable.
