commit b22b1f178f6799278d3178d894f37facb2085765 upstream.
Commit 7990696 uses the ext4_{set,clear}_inode_flags() functions to
change the i_flags automatically but fails to remove the error setting
of i_flags. So we still have the problem of trashing state flags.
Fix this by removing the assignment.

commit 6cb49835da0426f69a2931bc2a0a8156344b0e41 upstream.
We have one bug report from a validation team that we get the eDP
panel sequencing still somewhat wrong: We need to enable VDD while
switching off the panel and backlight. Unfortunately that reporter
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
again.
v2: I've forgotten to remove the vdd_off call in panel_off which is
now bogus. This essentially reverts

drm/i915/dp: Flush any outstanding work to turn the VDD off
v3: the current panel_off code forces off the vdd power, too. Which is
bogus and resulted in some funny warnings later on when we've tried to
do aux channel communications with just the vdd forced on. Fix this,
too.

commit 17038de5f16569a25343cf68668f3b657eafb00e upstream.
As we may kick off a delayed workqueue task to switch of the VDD lines, we
need to complete that task prior to turning off the panel (which itself
depends upon VDD being off).
v2: Don't cancel the outstanding work as this may trigger a deadlock

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.

commit f380f2c4a12e913356bd49f8790ec1063c4fe9f8 upstream.
This driver disables interrupt just after requesting it and enables it
later, after interface is up. However currently there is a time window
between request_irq() and disable_irq() where if interrupt arrives, the
driver oopses because it's not yet ready to process it. This can be
reproduced by inserting the module, associating and removing the module
multiple times.
Eliminate this race by setting IRQF_NOAUTOEN flag before request_irq().

commit aba336bd1d46d6b0404b06f6915ed76150739057 upstream.
The new merge_bvec_fn which calls the corresponding function
in subsidiary devices requires that mddev->merge_check_needed
be set if any child has a merge_bvec_fn.
However were were only setting that when a device was hot-added,
not when a device was present from the start.
This bug was introduced in 3.4 so patch is suitable for 3.4.y
kernels. However that are conflicts in raid10.c so a separate
patch will be needed for 3.4.y.

commit 0640113be25d283e0ff77a9f041e1242182387f0 upstream.
Cyrill Gorcunov reports that I broke the fdinfo files with commit
30a08bf2d31d ("proc: move fd symlink i_mode calculations into
tid_fd_revalidate()"), and he's quite right.
The tid_fd_revalidate() function is not just used for the <tid>/fd
symlinks, it's also used for the <tid>/fdinfo/<fd> files, and the
permission model for those are different.
So do the dynamic symlink permission handling just for symlinks, making
the fdinfo files once more appear as the proper regular files they are.
Of course, Al Viro argued (probably correctly) that we shouldn't do the
symlink permission games at all, and make the symlinks always just be
the normal 'lrwxrwxrwx'. That would have avoided this issue too, but
since somebody noticed that the permissions had changed (which was the
reason for that original commit 30a08bf2d31d in the first place), people
do apparently use this feature.
[ Basically, you can use the symlink permission data as a cheap "fdinfo"
replacement, since you see whether the file is open for reading and/or
writing by just looking at st_mode of the symlink. So the feature
does make sense, even if the pain it has caused means we probably
shouldn't have done it to begin with. ]

commit eee53537c476c947bf7faa1c916d2f5a0ae8ec93 upstream.
In the error path of the ppr_notifer it can happen that the
iommu->lock is taken recursivly. This patch fixes the
problem by releasing the iommu->lock before any notifier is
invoked. This also requires to move the erratum workaround
for the ppr-log (interrupt may be faster than data in the log)
one function up.

commit c1bf94ec1e12d76838ad485158aecf208ebd8fb9 upstream.
At some point pci_get_bus_and_slot started to enable
interrupts. Since this function is used in the
amd_iommu_resume path it will enable interrupts on resume
which causes a warning. The fix will use a cached pointer
to the root-bridge to re-enable the IOMMU in case the BIOS
is broken.

This patch fixes bug in macro radix_tree_for_each_contig().
If radix_tree_next_slot() sees NULL in next slot it returns NULL, but following
radix_tree_next_chunk() switches iterating into next chunk. As result iterating
becomes non-contiguous and breaks vfs "splice" and all its users.

commit 95599968d19db175829fb580baa6b68939b320fb upstream.
We can't have references held on pages in the s_buddy_cache while we are
trying to truncate its pages and put the inode. All the pages must be
gone before we reach clear_inode. This can only be gauranteed if we
can prevent new users from grabbing references to s_buddy_cache's pages.
The original bug can be reproduced and the bug fix can be verified by:

commit 79906964a187c405db72a3abc60eb9b50d804fbc upstream.
In commit 353eb83c we removed i_state_flags with 64-bit longs, But
when handling the EXT4_IOC_SETFLAGS ioctl, we replace i_flags
directly, which trashes the state flags which are stored in the high
32-bits of i_flags on 64-bit platforms. So use the the
ext4_{set,clear}_inode_flags() functions which use atomic bit
manipulation functions instead.

commit f3fc0210c0fc91900766c995f089c39170e68305 upstream.
The ext4_error() function is missing a call to save_error_info().
Since this is the function which marks the file system as containing
an error, this oversight (which was introduced in 2.6.36) is quite
significant, and should be backported to older stable kernels with
high urgency.

commit 967ac8af4475ce45474800709b12137aa7634c77 upstream.
In alloc_flex_gd(), when flexbg_size is large, kmalloc size would
overflow and flex_gd->groups would point to a buffer smaller than
expected, causing OOB accesses when it is used.
Note that in ext4_resize_fs(), flexbg_size is calculated using
sbi->s_log_groups_per_flex, which is read from the disk and only bounded
to [1, 31]. The patch returns NULL for too large flexbg_size.

[ Upstream commit 617c8c11236716dcbda877e764b7bf37c6fd8063 ]
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.

[ 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.

[ Upstream commit 0c1833797a5a6ec23ea9261d979aa18078720b74 ]
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.

fi. Other cpu might be accessing fi. Fixing it by delaying the releasing.
With the patch, we ran MTBF testing on Android mobile for 12 hours
and didn't trigger the issue.
Thank Eric for very detailed review/checking the issue.

radeon_cs_parser_init is called by both the legacy UMS
CS ioctl and the KMS CS ioctl. Protect KMS specific
pieces of the code by checking that rdev is not NULL.

commit 4a43faf54e9173b6acce37cf7f053fc9515a2cdf upstream.
Since commit 6a918bade9dab40aaef80559bd1169c69e8d69cb, the mxc_nand driver
fails with:
Driver must set ecc.strength when using hardware ECC
This is because nand_scan_tail checks for correct ecc strength
settings, so we must set them up before nand_scan_tail.

commit 2e24e32e2759348c9290404abad4f729f791bfad upstream.
The 'mtd_writev' interface calls the function assigned
to the '_write' field of a given mtd device if that is
not NULL. The block2mtd driver sets the '_writev' field
to the 'mtd_writev' function itself and thus causes a
endless loop.
This is caused by 1dbebd32562b3c2caeca35960e5cb00bfcc12900
(mtd: harmonize mtd_writev usage).
Remove the assignment from the block2mtd driver to fix the
issue.

commit c0525a6972d3f1fb83058ef503e183475d6e4e26 upstream.
When an NMI goes off and it sees that it preempted the debug stack,
to keep the debug stack safe, it changes the IDT to point to one that
does not modify the stack on breakpoint (to allow breakpoints in NMIs).
But the variable that gets set to know to undo it on exit never gets
cleared on exit. Thus every NMI will reset it on exit the first time
it is done even if it does not need to be reset.

commit bad1a753d4d4deb09d4bc0bac1dd4fc3298502e9 upstream.
When I added x32 ptrace to 3.4 kernel, I also include PTRACE_ARCH_PRCTL
support for x32 GDB For ARCH_GET_FS/GS, it takes a pointer to int64. But
at user level, ARCH_GET_FS/GS takes a pointer to int32. So I have to add
x32 ptrace to glibc to handle it with a temporary int64 passed to kernel and
copy it back to GDB as int32. Roland suggested that PTRACE_ARCH_PRCTL
is obsolete and x32 GDB should use fs_base and gs_base fields of
user_regs_struct instead.
Accordingly, remove PTRACE_ARCH_PRCTL completely from the x32 code to
avoid possible memory overrun when pointer to int32 is passed to
kernel.

commit 799243a389bde0de10fa21ca1ca453d2fe538b85 upstream.
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.

__mnt_make_shortterm() in there undoes the effect of __mnt_make_longterm()
we'd done back when we set ->mnt_ns non-NULL; it should not be done to
vfsmounts that had never gone through commit_tree() and friends. Kudos to

commit 02d7633fa567be7bf55a993b79d2a31b95ce2227 upstream.
In the case which is below,
1. acquire slab for cpu partial list
2. free object to it by remote cpu
3. page->freelist = t
then memory leak is occurred.
Change acquire_slab() not to zap freelist when it works for cpu partial list.
I think it is a sufficient solution for fixing a memory leak.
Below is output of 'slabinfo -r kmalloc-256'
when './perf stat -r 30 hackbench 50 process 4000 > /dev/null' is done.
