commit e07af133c3e2716db25e3e1e1d9f10c2088e9c1a upstream.
Also known as Verizon U620L.
The device is modeswitched from 1410:9020 to 1410:9022 by selecting the
4th USB configuration:
$ sudo usb_modeswitch –v 0x1410 –p 0x9020 –u 4
This configuration provides a ECM interface as well as TTYs ('Enterprise
Mode' according to the U620 Linux integration guide).

commit 705e63d2b29c8bbf091119084544d353bda70393 upstream.
There is a bit of a mess in the order of arguments to the ulpi write
callback. There is
int ulpi_write(struct ulpi *ulpi, u8 addr, u8 val)
in drivers/usb/common/ulpi.c;
struct usb_phy_io_ops {
...
int (*write)(struct usb_phy *x, u32 val, u32 reg);
}
in include/linux/usb/phy.h.
The callback registered by the musb driver has to comply to the latter,
but up to now had "offset" first which effectively made the function
broken for correct users. So flip the order and while at it also
switch to the parameter names of struct usb_phy_io_ops's write.

commit 19cd80a214821f4b558560ebd76bfb2c38b4f3d8 upstream.
It is not permitted to set task state before lock. usblp_wwait sets
the state to TASK_INTERRUPTIBLE and calls mutex_lock_interruptible.
Upon return from that function, the state will be TASK_RUNNING again.
This is clearly a bug and a warning is generated with LOCKDEP too:

commit 7cecd9ab80f43972c056dc068338f7bcc407b71c upstream.
According to SJA1000 data sheet error-warning (EI) interrupt is not
cleared by setting the controller in to reset-mode.
Then if we have the following case:
- system is suspended (echo mem > /sys/power/state) and SJA1000 is left
in operating state
- A bus error condition occurs which activates EI interrupt, system is
still suspended which means EI interrupt will be not be handled nor
cleared.
If the above two events occur, on resume there is no way to return the
SJA1000 to operating state, except to cycle power to it.
By simply reading the IR register on start we will clear any previous
conditions that could be present.

commit 1f9c6e1bc1ba5f8a10fcd6e99d170954d7c6d382 upstream.
There were several bugs here.
1) The done label was in the wrong place so we didn't copy any
information out when there was no command given.
2) We were using PAGE_SIZE as the size of the buffer instead of
"PAGE_SIZE - pos".
3) snprintf() returns the number of characters that would have been
printed if there were enough space. If there was not enough space
(and we had fixed the memory corruption bug #2) then it would result
in an information leak when we do simple_read_from_buffer(). I've
changed it to use scnprintf() instead.
I also removed the initialization at the start of the function, because
I thought it made the code a little more clear.

commit 2502d0ef272da7058ef303b849a2c8dc324c2e2e upstream.
The CPU_MAP register is duplicated for each CPUs at different addresses,
each instance being at a different address.
However, the code so far was using CONFIG_NR_CPUS to initialise the CPU_MAP
registers for each registers, while the SoCs embed at most 4 CPUs.
This is especially an issue with multi_v7_defconfig, where CONFIG_NR_CPUS
is currently set to 16, resulting in writes to registers that are not
CPU_MAP.

[ Upstream commit 48900cb6af4282fa0fb6ff4d72a81aa3dadb5c39 ]
virtio declares support for NETIF_F_FRAGLIST, but assumes
that there are at most MAX_SKB_FRAGS + 2 fragments which isn't
always true with a fraglist.
A longer fraglist in the skb will make the call to skb_to_sgvec overflow
the sg array, leading to memory corruption.
Drop NETIF_F_FRAGLIST so we only get what we can handle.

[ Upstream commit c02b05011fadf8e409e41910217ca689f2fc9d91 ]
When doing memcpy/memset of EQEs, we should use sizeof struct
mlx4_eqe as the base size and not caps.eqe_size which could be bigger.
If caps.eqe_size is bigger than the struct mlx4_eqe then we corrupt
data in the master context.
When using a 64 byte stride, the memcpy copied over 63 bytes to the
slave_eq structure. This resulted in copying over the entire eqe of
interest, including its ownership bit -- and also 31 bytes of garbage
into the next WQE in the slave EQ -- which did NOT include the ownership
bit (and therefore had no impact).
However, once the stride is increased to 128, we are overwriting the
ownership bits of *three* eqes in the slave_eq struct. This results
in an incorrect ownership bit for those eqes, which causes the eq to
seem to be full. The issue therefore surfaced only once 128-byte EQEs
started being used in SRIOV and (overarchitectures that have 128/256
byte cache-lines such as PPC) - e.g after commit 77507aa249ae
"net/mlx4_core: Enable CQE/EQE stride support".

[ Upstream commit 1acea4f6ce1b1c0941438aca75dd2e5c6b09db60 ]
We can't rely on PPPOX_ZOMBIE to decide whether to clear po->pppoe_dev.
PPPOX_ZOMBIE can be set by pppoe_disc_rcv() even when po->pppoe_dev is
NULL. So we have no guarantee that (sk->sk_state & PPPOX_ZOMBIE) implies
(po->pppoe_dev != NULL).
Since we're releasing a PPPoE socket, we want to release the pppoe_dev
if it exists and reset sk_state to PPPOX_DEAD, no matter the previous
value of sk_state. So we can just check for po->pppoe_dev and avoid any
assumption on sk->sk_state.

commit 0ca81a2840f77855bbad1b9f172c545c4dc9e6a4 upstream.
ib_send_cm_sidr_rep could sometimes erase the node from the sidr
(depending on errors in the process). Since ib_send_cm_sidr_rep is
called both from cm_sidr_req_handler and cm_destroy_id, cm_id_priv
could be either erased from the rb_tree twice or not erased at all.
Fixing that by making sure it's erased only once before freeing
cm_id_priv.

When pci_pool_alloc fails in mvs_task_prep then task->lldd_task stays

commit 2871c69e025e8bc507651d5a9cf81a8a7da9d24b upstream.
Commit 4c7e309340ff ("dm btree remove: fix bug in redistribute3") wasn't
a complete fix for redistribute3().
The redistribute3 function takes 3 btree nodes and shares out the entries
evenly between them. If the three nodes in total contained
(MAX_ENTRIES * 3) - 1 entries between them then this was erroneously getting
rebalanced as (MAX_ENTRIES - 1) on the left and right, and (MAX_ENTRIES + 1) in
the center.
Fix this issue by being more careful about calculating the target number
of entries for the left and right nodes.

commit 6d69bb536bac0d403d83db1ca841444981b280cd upstream.
Mapping an image with a long parent chain (e.g. image foo, whose parent
is bar, whose parent is baz, etc) currently leads to a kernel stack
overflow, due to the following recursion in the reply path:
rbd_osd_req_callback()
rbd_obj_request_complete()
rbd_img_obj_callback()
rbd_img_parent_read_callback()
rbd_obj_request_complete()
...
Limit the parent chain to 16 images, which is ~5K worth of stack. When
the above recursion is eliminated, this limit can be lifted.

commit 1f2c6651f69c14d0d3a9cfbda44ea101b02160ba upstream.
Currently we leak parent_spec and trigger a "parent reference
underflow" warning if rbd_dev_create() in rbd_dev_probe_parent() fails.
The problem is we take the !parent out_err branch and that only drops
refcounts; parent_spec that would've been freed had we called
rbd_dev_unparent() remains and triggers rbd_warn() in
rbd_dev_parent_put() - at that point we have parent_spec != NULL and
parent_ref == 0, so counter ends up being -1 after the decrement.
Redo rbd_dev_probe_parent() to fix this.

commit bae818ee1577c27356093901a0ea48f672eda514 upstream.
rbd requires stable pages, as it performs a crc of the page data before
they are send to the OSDs.
But since kernel 3.9 (patch 1d1d1a767206fbe5d4c69493b7e6d2a8d08cc0a0
"mm: only enforce stable page writes if the backing device requires
it") it is not assumed anymore that block devices require stable pages.
This patch sets the necessary flag to get stable pages back for rbd.
In a ceph installation that provides multiple ext4 formatted rbd
devices "bad crc" messages appeared regularly (ca 1 message every 1-2
minutes on every OSD that provided the data for the rbd) in the
OSD-logs before this patch. After this patch this messages are pretty
much gone (only ca 1-2 / month / OSD).

commit 2a6c521bb41ce862e43db46f52e7681d33e8d771 upstream.
On nv50+, we restrict the valid domains to just the one where the buffer
was originally created. However after the buffer is evicted to system
memory, we might move it back to a different domain that was not
originally valid. When sharing the buffer and retrieving its GEM_INFO
data, we still want the domain that will be valid for this buffer in a
pushbuf, not the one where it currently happens to be.
This resolves fdo#92504 and several others. These are due to suspend
evicting all buffers, making it more likely that they temporarily end up
in the wrong place.

commit cbf3ccd09d683abf1cacd36e3640872ee912d99b upstream.
During device assignment/deassignment the flags in the DTE
get lost, which might cause spurious faults, for example
when the device tries to access the system management range.
Fix this by not clearing the flags with the rest of the DTE.

The code to send the RX PN data (for each TID) to the firmware

all the TID data, leaving the remaining TIDs zeroed. This will
allow replays to actually be accepted by the firmware, which

commit 3ebe138ac642a195c7f2efdb918f464734421fd6 upstream.
If rbd_dev_image_probe() in rbd_dev_probe_parent() fails, header_name
is freed twice: once in rbd_dev_probe_parent() and then in its caller
rbd_dev_image_probe() (rbd_dev_image_probe() is called recursively to
handle parent images).
rbd_dev_probe_parent() is responsible for probing the parent, so it
shouldn't muck with clone's fields.

[ Upstream commit 436c2a5036b6ffe813310df2cf327d3b69be0734 ]
commit 3cc81d85ee01 ("asix: Don't reset PHY on if_up for ASIX 88772")
causes the ethernet on Arndale to no longer function. This appears to
be because the Arndale ethernet requires a full reset before it will
function correctly, however simply reverting the above patch causes
problems with ethtool settings getting reset.
It seems the problem is that the ethernet is not properly reset during
bind, and indeed the code in ax88772_bind that resets the device is a
very small subset of the actual ax88772_reset function. This patch uses
ax88772_reset in place of the existing reset code in ax88772_bind which
removes some code duplication and fixes the ethernet on Arndale.
It is still possible that the original patch causes some issues with
suspend and resume but that seems like a separate issue and I haven't
had a chance to test that yet.

[ Upstream commit 3cc81d85ee01e5a0b7ea2f4190e2ed1165f53c31 ]
I've noticed every time the interface is set to 'up,', the kernel
reports that the link speed is set to 100 Mbps/Full Duplex, even
when ethtool is used to set autonegotiation to 'off', half
duplex, 10 Mbps.
It can be tested by:
ifconfig eth0 down
ethtool -s eth0 autoneg off speed 10 duplex half
ifconfig eth0 up
Then checking 'dmesg' for the link speed.

Since commit 2b018d57ff18 ("pppoe: drop PPPOX_ZOMBIEs in pppoe_release"),

PPPOX_ZOMBIE _and_ reset po->pppoe_dev to NULL. This leads to the

commit 2bffa1503c5c06192eb1459180fac4416575a966 upstream.
The cleaner policy doesn't make use of the per cache block hint space in
the metadata (unlike the other policies). When switching from the
cleaner policy to mq or smq a NULL pointer crash (in dm_tm_new_block)
was observed. The crash was caused by bugs in dm-cache-metadata.c
when trying to skip creation of the hint btree.
The minimal fix is to change hint size for the cleaner policy to 4 bytes
(only hint size supported).

[ Upstream commit a951bc1e6ba58f11df5ed5ddc41311e10f5fd20b ]
The "follow" fail_over_mac policy is useful for multiport devices that
either become confused or incur a performance penalty when multiple
ports are programmed with the same MAC address, but the same MAC
address still may happened by this steps for this policy:
1) echo +eth0 > /sys/class/net/bond0/bonding/slaves
bond0 has the same mac address with eth0, it is MAC1.
2) echo +eth1 > /sys/class/net/bond0/bonding/slaves
eth1 is backup, eth1 has MAC2.
3) ifconfig eth0 down
eth1 became active slave, bond will swap MAC for eth0 and eth1,
so eth1 has MAC1, and eth0 has MAC2.
4) ifconfig eth1 down
there is no active slave, and eth1 still has MAC1, eth2 has MAC2.
5) ifconfig eth0 up
the eth0 became active slave again, the bond set eth0 to MAC1.
Something wrong here, then if you set eth1 up, the eth0 and eth1 will have the same
MAC address, it will break this policy for ACTIVE_BACKUP mode.
This patch will fix this problem by finding the old active slave and
swap them MAC address before change active slave.

The lkey table is allocated with with a get_user_pages() with an
order based on a number of index bits from a module parameter.
The underlying kernel code cannot allocate that many contiguous pages.
There is no reason the underlying memory needs to be physically
contiguous.
This patch:
- switches the allocation/deallocation to vmalloc/vfree
- caps the number of bits to 23 to insure at least 1 generation bit
o this matches the module parameter description

commit 72194739f54607bbf8cfded159627a2015381557 upstream.
Add a device quirk for the Logitech PTZ Pro Camera and its sibling the
ConferenceCam CC3000e Camera.
This fixes the failed camera enumeration on some boot, particularly on
machines with fast CPU.
Tested by connecting a Logitech PTZ Pro Camera to a machine with a
Haswell Core i7-4600U CPU @ 2.10GHz, and doing thousands of reboot cycles
while recording the kernel logs and taking camera picture after each boot.
Before the patch, more than 7% of the boots show some enumeration transfer
failures and in a few of them, the kernel is giving up before actually
enumerating the webcam. After the patch, the enumeration has been correct
on every reboot.
