crypto: aesni-intel - fix unaligned cbc decrypt for x86-32
commit
7c8d51848a88aafdb68f42b6b650c83485ea2f84 upstream.
The 32 bit variant of cbc(aes) decrypt is using instructions requiring
128 bit aligned memory locations but fails to ensure this constraint in
the code. Fix this by loading the data into intermediate registers with
load unaligned instructions.
This fixes reported general protection faults related to aesni.

hwrng: atmel-rng - fix race condition leading to repeated bits
commit
121daad8fd1dce63076fa55aaedd5dc3f981b334 upstream.
Data valid gets cleared by reading the ISR (status register) and NOT from
reading ODATA (data register). A new data word can become available between
checking ISR and reading ODATA, causing us to reuse the same data word next
time atmel_trng_read() gets called, if that happens before the following
data word is ready.
With this fixed, rngtest no longer complains of 'Continous run' errors.

iwlwifi: don't mess up the SCD when removing a key
commit
d6ee27eb13beab94056e0de52d81220058ca2297 upstream.
When we remove a key, we put a key index which was supposed
to tell the fw that we are actually removing the key. But
instead the fw took that index as a valid index and messed
up the SRAM of the device.
This memory corruption on the device mangled the data of
the SCD. The impact on the user is that SCD queue 2 got
stuck after having removed keys.
The message is the log that was printed is:
Queue 2 stuck for 10000ms
This doesn't seem to fix the higher queues that get stuck
from time to time.

powerpc: Fix kernel panic during kernel module load
commit
3c75296562f43e6fbc6cddd3de948a7b3e4e9bcf upstream.
This fixes a problem which can causes kernel oopses while loading
a kernel module.
According to the PowerPC EABI specification, GPR r11 is assigned
the dedicated function to point to the previous stack frame.
In the powerpc-specific kernel module loader, do_plt_call()
(in arch/powerpc/kernel/module_32.c), GPR r11 is also used
to generate trampoline code.
This combination crashes the kernel, in the case where the compiler
chooses to use a helper function for saving GPRs on entry, and the
module loader has placed the .init.text section far away from the
.text section, meaning that it has to generate a trampoline for
functions in the .init.text section to call the GPR save helper.
Because the trampoline trashes r11, references to the stack frame
using r11 can cause an oops.
The fix just uses GPR r12 instead of GPR r11 for generating the
trampoline code. According to the statements from Freescale, this is
safe from an EABI perspective.
I've tested the fix for kernel 2.6.33 on MPC8541.

But the BIOS uses general broadcast and legacy mode, and the

ext4: fix the free blocks calculation for ext3 file systems w/ uninit_bg
commit
b0dd6b70f0fda17ae9762fbb72d98e40a4f66556 upstream.
Ext3 filesystems that are converted to use as many ext4 file system
features as possible will enable uninit_bg to speed up e2fsck times.
These file systems will have a native ext3 layout of inode tables and
block allocation bitmaps (as opposed to ext4's flex_bg layout).
Unfortunately, in these cases, when first allocating a block in an
uninitialized block group, ext4 would incorrectly calculate the number
of free blocks in that block group, and then errorneously report that
the file system was corrupt:
EXT4-fs error (device vdd): ext4_mb_generate_buddy:741: group 30, 32254 clusters in bitmap, 32258 in gd
This problem can be reproduced via:
mke2fs -q -t ext4 -O ^flex_bg /dev/vdd 5g
mount -t ext4 /dev/vdd /mnt
fallocate -l 4600m /mnt/test
The problem was caused by a bone headed mistake in the check to see if a
particular metadata block was part of the block group.

cbf8ae32f66a9ceb8907ad9e16663c2a29e48990 upstream.
The memory the parameter __key points to is used as an iterator in
btree_get_prev(), so if we save off a bkey() pointer in retry_key and
then assign that to __key, we'll end up corrupting the btree internals
when we do eg
longcpy(__key, bkey(geo, node, i), geo->keylen);
to return the key value. What we should do instead is use longcpy() to
copy the key value that retry_key points to __key.
This can cause a btree to get corrupted by seemingly read-only
operations such as btree_for_each_safe.

target/file: Use O_DSYNC by default for FILEIO backends
commit
a4dff3043c231d57f982af635c9d2192ee40e5ae upstream.
Convert to use O_DSYNC for all cases at FILEIO backend creation time to
avoid the extra syncing of pure timestamp updates with legacy O_SYNC during
default operation as recommended by hch. Continue to do this independently of
Write Cache Enable (WCE) bit, as WCE=0 is currently the default for all backend
devices and enabled by user on per device basis via attrib/emulate_write_cache.
This patch drops the now unnecessary fd_buffered_io= token usage that was
originally signalling when to explictly disable O_SYNC at backend creation
time for buffered I/O operation. This can end up being dangerous for a number
of reasons during physical node failure, so go ahead and drop this option
for now when O_DSYNC is used as the default.
Also allow explict FUA WRITEs -> vfs_fsync_range() call to function in
fd_execute_cmd() independently of WCE bit setting.

skb: avoid unnecessary reallocations in __skb_cow
[ Upstream commit

At the beginning of __skb_cow, headroom gets set to a minimum of
NET_SKB_PAD. This causes unnecessary reallocations if the buffer was not
cloned and the headroom is just below NET_SKB_PAD, but still more than the
amount requested by the caller.
This was showing up frequently in my tests on VLAN tx, where
vlan_insert_tag calls skb_cow_head(skb, VLAN_HLEN).
Locally generated packets should have enough headroom, and for forward
paths, we already have NET_SKB_PAD bytes of headroom, so we don't need to
add any extra space here.

l2tp: fix oops in L2TP IP sockets for connect() AF_UNSPEC case
[ Upstream commit
c51ce49735c183ef2592db70f918ee698716276b ]
An application may call connect() to disconnect a socket using an
address with family AF_UNSPEC. The L2TP IP sockets were not handling
this case when the socket is not bound and an attempt to connect()
using AF_UNSPEC in such cases would result in an oops. This patch
addresses the problem by protecting the sk_prot->disconnect() call
against trying to unhash the socket before it is bound.
The patch also adds more checks that the sockaddr supplied to bind()
and connect() calls is valid.

Since commit
ad0081e43a
"ipv6: Fragment locally generated tunnel-mode IPSec6 packets as needed"
the fragment of packets is incorrect.
because tunnel mode needs IPsec headers and trailer for all fragments,
while on transport mode it is sufficient to add the headers to the
first fragment and the trailer to the last.
so modify mtu and maxfraglen base on ipsec mode and if fragment is first
or last.
with my test,it work well(every fragment's size is the mtu)
and does not trigger slow fragment path.
Changes from v1:
though optimization, mtu_prev and maxfraglen_prev can be delete.
replace xfrm mode codes with dst_entry's new frag DST_XFRM_TUNNEL.
add fuction ip6_append_data_mtu to make codes clearer.

Subject: [PATCH] btusb: add device entry for Broadcom SoftSailing
and noticed it wasn't working on an HP Elitebook. Looking into the patch I
noticed a very subtle typo in the ids. The patch has '0x05ac' instead of
'0x0a5c'. A snippet of the lsusb -v output also shows this:
Bus 002 Device 003: ID 0a5c:21e1 Broadcom Corp.
Device Descriptor:
bLength 18
bDescriptorType 1
bcdUSB 2.00
bDeviceClass 255 Vendor Specific Class
bDeviceSubClass 1

bcdDevice 1.12
iManufacturer 1 Broadcom Corp
iProduct 2 BCM20702A0
iSerial 3
60D819F0338C
bNumConfigurations 1
Looking at other Broadcom ids, the fix matches them whereas the original patch
matches Apple's ids.
Tested on an HP Elitebook 8760w. The btusb binds and the userspace stuff loads
correctly.

When a file is truncated with truncate()/ftruncate() and then closed,
iversion is not updated. This patch uses ATTR_SIZE flag as an indication
to increment iversion.
Mimi said:
On fput(), i_version is used to detect and flag files that have changed
and need to be re-measured in the IMA measurement policy. When a file
is truncated with truncate()/ftruncate() and then closed, i_version is
not updated. As a result, although the file has changed, it will not be
re-measured and added to the IMA measurement list on subsequent access.

The breakage is caused because the function template in

That means that in the modular case (which is every distro), the
scsi_wait_scan module does a simple async_synchronize_full() instead of

mm: fix faulty initialization in vmalloc_init()
commit
dbda591d920b4c7692725b13e3f68ecb251e9080 upstream.
The transfer of ->flags causes some of the static mapping virtual
addresses to be prematurely freed (before the mapping is removed) because
VM_LAZY_FREE gets "set" if tmp->flags has VM_IOREMAP set. This might
cause subsequent vmalloc/ioremap calls to fail because it might allocate
one of the freed virtual address ranges that aren't unmapped.
va->flags has different types of flags from tmp->flags. If a region with
VM_IOREMAP set is registered with vm_area_add_early(), it will be removed
by __purge_vmap_area_lazy().
Fix vmalloc_init() to correctly initialize vmap_area for the given
vm_struct.
Also initialise va->vm. If it is not set, find_vm_area() for the early
vm regions will always fail.

hugetlb: fix resv_map leak in error path
commit
c50ac050811d6485616a193eb0f37bfbd191cc89 upstream.
When called for anonymous (non-shared) mappings, hugetlb_reserve_pages()
does a resv_map_alloc(). It depends on code in hugetlbfs's
vm_ops->close() to release that allocation.
However, in the mmap() failure path, we do a plain unmap_region() without
the remove_vma() which actually calls vm_ops->close().
This is a decent fix. This leak could get reintroduced if new code (say,
after hugetlb_reserve_pages() in hugetlbfs_file_mmap()) decides to return
an error. But, I think it would have to unroll the reservation anyway.

mm: consider all swapped back pages in used-once logic
commit
e48982734ea0500d1eba4f9d96195acc5406cad6 upstream.
Commit
645747462435 ("vmscan: detect mapped file pages used only once")
made mapped pages have another round in inactive list because they might
be just short lived and so we could consider them again next time. This
heuristic helps to reduce pressure on the active list with a streaming
IO worklods.
This patch fixes a regression introduced by this commit for heavy shmem
based workloads because unlike Anon pages, which are excluded from this
heuristic because they are usually long lived, shmem pages are handled
as a regular page cache.
This doesn't work quite well, unfortunately, if the workload is mostly
backed by shmem (in memory database sitting on 80% of memory) with a
streaming IO in the background (backup - up to 20% of memory). Anon
inactive list is full of (dirty) shmem pages when watermarks are hit.
Shmem pages are kept in the inactive list (they are referenced) in the
first round and it is hard to reclaim anything else so we reach lower
scanning priorities very quickly which leads to an excessive swap out.
Let's fix this by excluding all swap backed pages (they tend to be long
lived wrt. the regular page cache anyway) from used-once heuristic and
rather activate them if they are referenced.
The customer's workload is shmem backed database (80% of RAM) and they
are measuring transactions/s with an IO in the background (20%).
Transactions touch more or less random rows in the table. The
transaction rate fell by a factor of 3 (in the worst case) because of
commit
64574746. This patch restores the previous numbers.

The vma length in dup_mmap is calculated and stored in a unsigned int,

#include <stdio.h>
#include <unistd.h>
#include <sys/mman.h>

#define EXTENT 16393

for (i = 0; i < EXTENT; i++) {
m = mmap(NULL, (size_t) 1 * 1024 * 1024 * 1024L,
PROT_READ | PROT_WRITE, MAP_PRIVATE | MAP_ANONYMOUS, 0, 0);
if (m == (void *)-1)
printf("MMAP Failed: %d\n", m);
else
printf("%d : MMAP returned %p\n", i, m);
r = fork();

printf("FORK Failed: %d\n", r);
else if (r > 0)
wait(NULL);
}

}
Increase the storage size of the result to unsigned long, which is
sufficient for storing the difference between addresses.

And the addition of pci_set_master() is fairly self-explanatory.

drm/i915: always use RPNSWREQ for turbo change requests
commit
89ba829e38bd500f438bc08af4229204c8ed7f35 upstream.
Media turbo requests can either use RPVSWREQ or RPNSWREQ to indicate
what the interrupt handler should do. Since we only deal with the
latter in our turbo code, make the media engine use that for turbo
requests.

Fix TV programming: add vblank wait after TV_CTL writes
Fxies FDO bug #14000; we need to wait for vblank after
writing TV_CTL or following "DPMS on" calls may not actually enable the output.
v2: As suggested by Chris Wilson, add a small comment to ensure that
no one accidentally removes this vblank wait again - there really
seems to be no sane explanation for why we need it, but it is
required.

We have one bug report from a validation team that we get the eDP

seems to have fallen off the earth :(
For another reporter this actually fixes a black panel issue because
without this the backlight/panel gets confused and doesn't light up

Fix dm-multipath starvation when scsi host is busy
commit
b7e94a1686c5daef4f649f7f4f839cc294f07710 upstream.
block congestion control doesn't have any concept of fairness across
multiple queues. This means that if SCSI reports the host as busy in
the queue congestion control it can result in an unfair starvation
situation in dm-mp if there are multiple multipath devices on the same
host. For example:
http://www.redhat.com/archives/dm-devel/2012-May/msg00123.html
The fix for this is to report only the sdev busy state (and ignore the
host busy state) in the block congestion control call back.
The host is still congested, but the SCSI subsystem will sort out the
congestion in a fair way because it knows the relation between the
queues and the host.

cifs: fix oops while traversing open file list (try #4)

While traversing the linked list of open file handles, if the identfied
file handle is invalid, a reopen is attempted and if it fails, we
resume traversing where we stopped and cifs can oops while accessing
invalid next element, for list might have changed.
So mark the invalid file handle and attempt reopen if no
valid file handle is found in rest of the list.
If reopen fails, move the invalid file handle to the end of the list
and start traversing the list again from the begining.
Repeat this four times before giving up and returning an error if
file reopen keeps failing.
