Subject: [PATCH] KVM: Fix buffer overflow in kvm_set_irq()
commit f2ebd422f71cda9c791f76f85d2ca102ae34a1ed upstream.
kvm_set_irq() has an internal buffer of three irq routing entries, allowing
connecting a GSI to three IRQ chips or on MSI. However setup_routing_entry()
does not properly enforce this, allowing three irqchip routes followed by
an MSI route to overflow the buffer.
Fix by ensuring that an MSI entry is added to an empty list.

Subject: [1/5] macvtap: zerocopy: fix offset calculation when building skb
commit 3afc9621f15701c557e60f61eba9242bac2771dd upstream.
This patch fixes the offset calculation when building skb:
- offset1 were used as skb data offset not vector offset
- reset offset to zero only when we advance to next vector

When get_user_pages_fast() fails to get all requested pages, we could not use

Current the SKBTX_DEV_ZEROCOPY is set unconditionally after
zerocopy_sg_from_iovec(), this would lead NULL pointer when macvtap
fails to build zerocopy skb because destructor_arg was not
initialized. Solve this by set this flag after the skb were built

Subject: macvtap: zerocopy: validate vectors before building skb
commit b92946e2919134ebe2a4083e4302236295ea2a73 upstream.
There're several reasons that the vectors need to be validated:
- Return error when caller provides vectors whose num is greater than UIO_MAXIOV.
- Linearize part of skb when userspace provides vectors grater than MAX_SKB_FRAGS.
- Return error when userspace provides vectors whose total length may exceed
- MAX_SKB_FRAGS * PAGE_SIZE.

Admittedly it is almost certain that no one this side of the
Moon would use such a card in an Alpha but it does get us
closer to being able to build allyesconfig or allmodconfig,

When holding the mmap_sem for reading, pmd_offset_map_lock should only
run on a pmd_t that has been read atomically from the pmdp pointer,
otherwise we may read only half of it leading to this crash.

This should be a longstanding bug affecting x86 32bit PAE without THP.
Only archs with 64bit large pmd_t and 32bit unsigned long should be
affected.
With THP enabled the barrier() in pmd_none_or_trans_huge_or_clear_bad()
would partly hide the bug when the pmd transition from none to stable,
by forcing a re-read of the *pmd in pmd_offset_map_lock, but when THP is
enabled a new set of problem arises by the fact could then transition
freely in any of the none, pmd_trans_huge or pmd_trans_stable states.
So making the barrier in pmd_none_or_trans_huge_or_clear_bad()
unconditional isn't good idea and it would be a flakey solution.
This should be fully fixed by introducing a pmd_read_atomic that reads
the pmd in order with THP disabled, or by reading the pmd atomically
with cmpxchg8b with THP enabled.
Luckily this new race condition only triggers in the places that must
already be covered by pmd_none_or_trans_huge_or_clear_bad() so the fix
is localized there but this bug is not related to THP.
NOTE: this can trigger on x86 32bit systems with PAE enabled with more
than 4G of ram, otherwise the high part of the pmd will never risk to be
truncated because it would be zero at all times, in turn so hiding the
SMP race.
This bug was discovered and fully debugged by Ulrich, quote:
----
[..]
pmd_none_or_trans_huge_or_clear_bad() loads the content of edx and
eax.
496 static inline int pmd_none_or_trans_huge_or_clear_bad(pmd_t
*pmd)
497 {
498 /* depend on compiler for an atomic pmd read */
499 pmd_t pmdval = *pmd;

// eax = PTE page table low address

[..]
Please note that the PMD is not read atomically. These are two "mov"
instructions where the high order bits of the PMD entry are fetched
first. Hence, the above machine code is prone to the following race.
- The PMD entry {high|low} is 0x0000000000000000.
The "mov" at 0xc0507a84 loads 0x00000000 into edx.
- A page fault (on another CPU) sneaks in between the two "mov"
instructions and instantiates the PMD.
- The PMD entry {high|low} is now 0x00000003fda38067.
The "mov" at 0xc0507a8e loads 0xfda38067 into eax.

From: Andrea Arcangeli <aarcange@redhat.com>
Subject: thp: avoid atomic64_read in pmd_read_atomic for 32bit PAE
In the x86 32bit PAE CONFIG_TRANSPARENT_HUGEPAGE=y case while holding the
mmap_sem for reading, cmpxchg8b cannot be used to read pmd contents under
Xen.
So instead of dealing only with "consistent" pmdvals in
pmd_none_or_trans_huge_or_clear_bad() (which would be conceptually
simpler) we let pmd_none_or_trans_huge_or_clear_bad() deal with pmdvals
where the low 32bit and high 32bit could be inconsistent (to avoid having
to use cmpxchg8b).
The only guarantee we get from pmd_read_atomic is that if the low part of
the pmd was found null, the high part will be null too (so the pmd will be
considered unstable). And if the low part of the pmd is found "stable"
later, then it means the whole pmd was read atomically (because after a
pmd is stable, neither MADV_DONTNEED nor page faults can alter it anymore,
and we read the high part after the low part).
In the 32bit PAE x86 case, it is enough to read the low part of the pmdval
atomically to declare the pmd as "stable" and that's true for THP and no
THP, furthermore in the THP case we also have a barrier() that will
prevent any inconsistent pmdvals to be cached by a later re-read of the
*pmd.

commit 68aad78c5023b8aa82da99b47f9d8cf40e8ca453 upstream.
Per the mention made by Ben Hutchings that strlcpy is now the preferred
string copy routine for a .get_drvinfo routine, do a bit of floor
sweeping and convert some of the as-yet unconverted ethernet drivers to
it.

Subject: [PATCH 04/58] be2net: don't log more than one error on detecting
EEH/UE errors
commit 434b3648e9a58600cea5f3a1a0a7a89048e4df61 upstream.
Currently we're spamming error messages each time a FW cmd call is made
while in EEH/UE error state. One log msg on error detection is enough.

Subject: [PATCH 05/58] be2net: stop issuing FW cmds if any cmd times out
commit 6589ade019dcab245d3bb847370f855b56cdf6ad upstream.
A FW cmd timeout (with a sufficiently large timeout value in the
order of tens of seconds) indicates an unresponsive FW. In this state
issuing further cmds and waiting for a completion will only stall the process.

commit 293c4a7d9b95d0beeb5df03c14bd35bc21f9e6f2 upstream.
Lancer uses V1 version of TXQ create. This command needs interface
id for TX queue creation. Rearrange code such that tx queue create
is after interface create. As TXQ create is now called after MCC
ring create use MCC instead of MBOX.

commit 5d5adb93d0efca8b47cc3e649a41ba650ff3d270 upstream.
To enable VLAN promiscous mode, the HW interface should be created
with VLAN promiscous capability in Lancer. Add this capability during
creation of the HW interface.

commit 590c391dd362479b27a67c8d797ce348c5798b93 upstream.
SR-IOV implementation is Lancer has changed in following ways -
1)PF driver assigns one MAC addresses for VF using COMMON_SET_IFACE_MAC_LIST.
2)VF driver queries its MAC address using COMMON_GET_IFACE_MAC_LIST command
and assigns it to its interface.

Subject: [PATCH 12/58] be2net: Fix error recovery paths
commit 3bb62f4f95ba004048bafb460179b5db33aff787 upstream.
When TX queues are created again after error recovery,
netif_set_real_num_tx_queues() is invoked to update number of real
TX queues created. rtnl lock needs to be held when invoking this routine.

commit 110b82bc6265a48c1a0bf198109bed325ed055e2 upstream.
The ethtool "-g" option is supposed to report the max queue length and
user modified queue length for RX and TX queues. be2net doesn't support
user modification of queue lengths. So, the correct values for these
would be the max numbers.
be2net incorrectly reports the queue used values for these fields.

Subject: [PATCH 20/58] be2net: refactor/cleanup vf configuration code
commit 11ac75ed1eb9d8f5ff067fa9a82ebf5075989281 upstream.
- use adapter->num_vfs (and not the module param) to store the actual
number of vfs created. Use the same variable to reflect SRIOV
enable/disable state. So, drop the adapter->sriov_enabled field.
- use for_all_vfs() macro in VF configuration code
- drop the "vf_" prefix for the fields of be_vf_cfg; the prefix is
redundant and removing it helps reduce line wrap

Subject: [PATCH 22/58] be2net: Fix INTx processing for Lancer
commit 93c86700c0ae3a1407b979073f423e62e29372c1 upstream.
Lancer does not have HW registers to indicate the EQ causing the INTx
interrupt. As a result EQE entries of one EQ may be consumed when interrupt
is caused by another EQ. Fix this by arming CQs at the end of NAPI poll
routine to regenerate the EQEs.

Subject: [PATCH 25/58] be2net: query link status in be_open()
commit b236916a68d923acff15787b5439d7d684c17ae5 upstream.
be2net gets an async link status notification from the FW when it creates
an MCC queue. There are some cases in which this gratuitous notification
is not received from FW. To cover this explicitly query the link status
in be_open().

Subject: [PATCH 27/58] be2net: create RSS rings even in multi-channel configs
commit df505eb804d5221c3164ebecd1286cb7fc7f49ba upstream.
Currently RSS rings are not created in a multi-channel config.
RSS rings can be created on one (out of four) interfaces per port in a
multi-channel config. Doing this insulates the driver from a FW bug wherin
multi-channel config is wrongly reported even when not enabled. This also
helps performance in a multi-channel config, as one interface per port gets
RSS rings.

Subject: [PATCH 28/58] be2net: allocate more headroom in incoming skbs
commit bb349bb4b19b39830e0486aedfd7c7dca23b7baf upstream.
Allocation of 64 bytes in skb headroom is not enough if we have to pull
ethernet + ipv6 + tcp headers, and/or extra tunneling header.
Its currently not noticed because netdev_alloc_skb_ip_align(64) give us
more room, thanks to power-of-two kmalloc() roundups.
Make sure we ask for 128 bytes so that side effects of upcoming patches
from Ian Campbell dont decrease benet rx performance, because of extra
skb head reallocations.

Also rename a few counters appropritely and delete 2 counters that are not

vlan_mismatch_drops does not exist in BE3 and is accounted for in
address_mismatch_drops. Do the same thing for BE2 and Lancer.

Subject: [PATCH 34/58] be2net: fix tx completion cleanup
commit 0ae57bb3df562e57ac89ad7bc524b6f2e83235f9 upstream.
As a part of be_close(), instead of waiting for a max of 200ms for each TXQ,
wait for a total of 200ms for completions from all TXQs to arrive.

Subject: [PATCH 35/58] be2net: reset queue address after freeing
commit 1cfafab965198bc0d9cb794af5065d0797969727 upstream.
This will prevent double free in some cases where be_clear() is called
for cleanup when be_setup() fails half-way.

Subject: [PATCH 44/58] be2net: Fix VLAN/multicast packet reception
commit 0fc16ebf69fc57b42110712eaaf8a6aa2492afbe upstream.
VLAN and multicast hardware filters are limited and can get
exhausted in adapters with many PCI functions. If setting
a VLAN or multicast filter fails due to lack of sufficient
hardware resources, these packets get dropped. Fix this by
switching to VLAN or multicast promiscous mode so that these
packets are not dropped.

Subject: [PATCH 47/58] be2net: Fix traffic stall INTx mode
commit af311fe31015e2b27bd65e22fc103230fb3a78b7 upstream.
EQ is getting armed wrongly in INTx mode as INTx interrupt is taking
some time to deassert. This can cause another interrupt while NAPI is
scheduled and scheduling a NAPI in interrupt does not take effect.
This causes interrupt to be missed and traffic stalls. Fixing this by
preventing wrong arming of EQ.

Subject: [PATCH 49/58] be2net: Fix wrong status getting returned for MCC
commands
commit 652bf64622f32c938dd4a8738ba12d51dc9fbdd4 upstream.
MCC Response CQEs are processed as part of NAPI poll routine and
also synchronously. If MCC completions are consumed by NAPI poll
routine, wrong status is returned to synchronously waiting routine.
Fix this by getting status of MCC command from command response
instead of response CQEs.

commit 22ca7a6e9a68a7e0c149b22ebed9dcd106245bb7 upstream.
This renders the interface view somewhat inconsistent from the Host OS POV
considering the rest of the interfaces are showing their respective speeds
based on the bandwidth assigned to them.

Subject: [PATCH 58/58] be2net: avoid disabling sriov while VFs are assigned
commit 39f1d94d300a58eb3e9b851d077cada4e2fa9d46 upstream.
Calling pci_disable_sriov() while VFs are assigned to VMs causes
kernel panic. This patch uses PCI_DEV_FLAGS_ASSIGNED bit state of the
VF's pci_dev to avoid this. Also, the unconditional function reset cmd
issued on a PF probe can delete the VF configuration for the
previously enabled VFs. A scratchpad register is now used to issue a
function reset only when needed (i.e., in a crash dump scenario.)

Subject: [PATCH 1/7] codel: Controlled Delay AQM
commit 76e3cc126bb223013a6b9a0e2a51238d1ef2e409 upstream.
An implementation of CoDel AQM, from Kathleen Nichols and Van Jacobson.
http://queue.acm.org/detail.cfm?id=2209336
This AQM main input is no longer queue size in bytes or packets, but the
delay packets stay in (FIFO) queue.
As we don't have infinite memory, we still can drop packets in enqueue()
in case of massive load, but mean of CoDel is to drop packets in
dequeue(), using a control law based on two simple parameters :
target : target sojourn time (default 5ms)
interval : width of moving time window (default 100ms)
Based on initial work from Dave Taht.
Refactored to help future codel inclusion as a plugin for other linux
qdisc (FQ_CODEL, ...), like RED.
include/net/codel.h contains codel algorithm as close as possible than
Kathleen reference.
net/sched/sch_codel.c contains the linux qdisc specific glue.
Separate structures permit a memory efficient implementation of fq_codel
(to be sent as a separate work) : Each flow has its own struct
codel_vars.
timestamps are taken at enqueue() time with 1024 ns precision, allowing
a range of 2199 seconds in queue, and 100Gb links support. iproute2 uses
usec as base unit.
Selected packets are dropped, unless ECN is enabled and packets can get
ECN mark instead.
Tested from 2Mb to 10Gb speeds with no particular problems, on ixgbe and
tg3 drivers (BQL enabled).
Usage: tc qdisc ... codel [ limit PACKETS ] [ target TIME ]
[ interval TIME ] [ ecn ]
qdisc codel 10: parent 1:1 limit 2000p target 3.0ms interval 60.0ms ecn
Sent 13347099587 bytes 8815805 pkt (dropped 0, overlimits 0 requeues 0)
rate 202365Kbit 16708pps backlog 113550b 75p requeues 0
count 116 lastcount 98 ldelay 4.3ms dropping drop_next 816us
maxpacket 1514 ecn_mark 84399 drop_overlimit 0
CoDel must be seen as a base module, and should be used keeping in mind
there is still a FIFO queue. So a typical setup will probably need a
hierarchy of several qdiscs and packet classifiers to be able to meet
whatever constraints a user might have.
One possible example would be to use fq_codel, which combines Fair
Queueing and CoDel, in replacement of sfq / sfq_red.

Subject: [PATCH 2/7] codel: use Newton method instead of sqrt() and divides
commit 536edd67109df5e0cdb2c4ee759e9bade7976367 upstream.
As Van pointed out, interval/sqrt(count) can be implemented using
multiplies only.
http://en.wikipedia.org/wiki/Methods_of_computing_square_roots#Iterative_methods_for_reciprocal_square_roots
This patch implements the Newton method and reciprocal divide.
Total cost is 15 cycles instead of 120 on my Corei5 machine (64bit
kernel).
There is a small 'error' for count values < 5, but we don't really care.
I reuse a hole in struct codel_vars :
- pack the dropping boolean into one bit
- use 31bit to store the reciprocal value of sqrt(count).

Subject: [PATCH 3/7] fq_codel: Fair Queue Codel AQM
commit 4b549a2ef4bef9965d97cbd992ba67930cd3e0fe upstream.
Fair Queue Codel packet scheduler
Principles :
- Packets are classified (internal classifier or external) on flows.
- This is a Stochastic model (as we use a hash, several flows might
be hashed on same slot)
- Each flow has a CoDel managed queue.
- Flows are linked onto two (Round Robin) lists,
so that new flows have priority on old ones.
- For a given flow, packets are not reordered (CoDel uses a FIFO)
- head drops only.
- ECN capability is on by default.
- Very low memory footprint (64 bytes per flow)
tc qdisc ... fq_codel [ limit PACKETS ] [ flows number ]
[ target TIME ] [ interval TIME ] [ noecn ]
[ quantum BYTES ]
defaults : 1024 flows, 10240 packets limit, quantum : device MTU
target : 5ms (CoDel default)
interval : 100ms (CoDel default)
Impressive results on load :

Much better than SFQ because of priority given to new flows, and fast
path dirtying less cache lines.

Subject: [PATCH 6/7] codel: use u16 field instead of 31bits for rec_inv_sqrt
commit 6ff272c9ad65eda219cd975b9da2dbc31cc812ee upstream.
David pointed out gcc might generate poor code with 31bit fields.
Using u16 is more than enough and permits a better code output.
Also make the code intent more readable using constants, fixed point arithmetic
not being trivial for everybody.

Subject: [PATCH 7/7] fq_codel: should use qdisc backlog as threshold
commit 865ec5523dadbedefbc5710a68969f686a28d928 upstream.
codel_should_drop() logic allows a packet being not dropped if queue
size is under max packet size.
In fq_codel, we have two possible backlogs : The qdisc global one, and
the flow local one.
The meaningful one for codel_should_drop() should be the global backlog,
not the per flow one, so that thin flows can have a non zero drop/mark
probability.

Subject: Input: wacom - add Intuos5 Touch Ring/ExpressKey support
commit f860e581fd473250c6dcbd3e13d576b6197e4694 upstream.
Intuos5 uses a new report type for Touch Ring and ExpressKey data.
Note that data from the capacitive sensors present on the ExpressKeys
will be ignored until a proper way is found to expose it.

Subject: Input: wacom - add Intuos5 Touch Ring LED support
commit 9b5b95dd516a13d53ecf9217672d2116f05097bc upstream.
The Touch Ring LEDs on Intuos5 tablets use a different report
format which supports only 4 levels of brightness. We remap
the 7-bit value obtained from sysfs to an appropriate value
for the tablet. Control of the crop mark LEDs (new to the I5)
is left for a later patch.

Subject: Input: wacom - add Intuos5 multitouch sensor support
commit ae584ca473289377dd7fd8c61439db4bfab5489a upstream.
Intuos5 tablets with PTH-* model numbers include a multitouch sensor
which use the same touch reports as the 3rd-generation Bamboo. No
useful information is in the HID descriptor for the touch interface
so hardcoded values are used during setup.

From: Ping Cheng <pinglinux@gmail.com>
Date: Sun, 29 Apr 2012 21:09:18 -0700
Subject: Input: wacom - add 0xE5 (MT device) support
commit 1963518b9b1b8019d33b4b08deee6f873ffa2730 upstream.
Main part of patch is adding support for a new Wacom MT touch
packet and labels these devices using MTSCREEN type.
Other items of interest:
Delete some duplicate code in HID parsing for Y info since
its already done in X path.
In wacom_query_tablet_data(), only invoke the set report
that requests tablets to send Wacom Touch packets for
Finger interfaces. Mostly, this is to make code intent clear.

Subject: [PATCH 26/26] Input: wacom - return proper error if
usb_get_extra_descriptor() fails
commit a882c932a628cbab17752fc8b1c94692f95bbf9a upstream.
Instead of returning 1 (which is not even negative) let's capture and return
error codde returned by usb_get_extra_descriptor().

Subject: wacom: do not crash when retrieving touch_max
Bug-Debian: http://bugs.debian.org/678798
When rep_data was an array
unsigned char rep_data[2];
spelling its address as &rep_data was perfectly valid, but now that
it is dynamically allocated
unsigned char *rep_data = kmalloc(2, GFP_KERNEL);
that expression returns a pointer to the pointer rather than to the
array itself. Regression introduced by commit f393ee2b814e (Input:
wacom - retrieve maximum number of touch points, 2012-04-29).
[jn: from mailing list discussion, with new description.
This change is also available as part of a larger commit in the
input-wacom repository.]

Subject: wacom: leave touch_max as is if predefined
Bug-Debian: http://bugs.debian.org/677164
Another fixup to f393ee2b814e (Input: wacom - retrieve maximum number
of touch points, 2012-04-29). The 0xE6 tablet in the Thinkpad x220t
reports the wrong value for MAXCONTACTS so the hardcoded value must
take precedence.

commit ff3e660b5a881b401b2b6735aa5334f433237dcb

orion/kirkwood: create a generic function for gpio led blinking
dns323 and (at least) iconnect platforms are using hw led blinking, so,
instead of having 2 identicals .gpio_blink_set gpio-led hooks, move
dns323 code into gpio.c

Date: Wed Apr 18 23:16:39 2012 +0200
kirkwood/orion: fix orion_gpio_set_blink
gpio registers are for 32 gpios. Given that orion_gpio_set_blink is called
directly and not through gpiolib, it needs to make sure that the pin value
given to the internal functions are between 0 and 31.

Subject: net: drop NET dependency from HAVE_BPF_JIT
commit e47b65b032f2997aa0a7392ecdf656c86d4d7561 upstream.
There is no point having the NET dependency on the select target, as it
forces all users to depend on NET to tell they support BPF_JIT. Move
the config option to the bottom of the file - this could be a nice place
also for future "selectable" config symbols.
Fix up all users to drop the dependency on NET now that it is not
required to supress warnings for non-NET builds.
