#1302028 — [PATCH 4.2.y-ckt 146/211] IB/core: avoid 32-bit warning

4.2.8-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@arndb.de>

commit 5d1e623591dfaa64a59ecdac420adc16125524d4 upstream.

The INIT_UDATA() macro requires a pointer or unsigned long argument for
both input and output buffer, and all callers had a cast from when
the code was merged until a recent restructuring, so now we get

core/uverbs_cmd.c: In function 'ib_uverbs_create_cq':
core/uverbs_cmd.c:1481:66: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

This makes the code behave as before by adding back the cast to
unsigned long.

#1302029 — [PATCH 4.2.y-ckt 134/211] hsi: fix double kfree

4.2.8-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Geliang Tang <geliangtang@163.com>

commit f098a045350ecd6045f2f2d5a50fecf2a98962d7 upstream.

When device_register() fails, kfree() is called in hsi_client_release(),
hence there is no need to call kfree in err3 again.

#1302030 — [PATCH 4.2.y-ckt 145/211] RDMA/cxgb4: re-fix 32-bit build warning

4.2.8-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@arndb.de>

commit b61e564af85bde408456f779eb267a37a64dc522 upstream.

Casting a pointer to __be64 produces a warning on 32-bit architectures:

drivers/infiniband/hw/cxgb4/mem.c:147:20: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
    req->wr.wr_lo = (__force __be64)&wr_wait;

This was fixed at least twice for this driver in different places,
and accidentally reverted once more. This puts the correct version
back in place.

#1302031 — [PATCH 4.2.y-ckt 137/211] ALSA: fireworks/bebob/oxfw/dice: enable to make as built-in

4.2.8-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Takashi Sakamoto <o-takashi@sakamocchi.jp>

commit df4833886f91eea0d20e6e97066adab308625ef8 upstream.

When committed to upstream, these four modules had wrong entries for
Makefile. This forces them to be loadable modules even if they're set
as built-in.

This commit fixes this bug.

Fixes: fd6f4b0dc167('ALSA: bebob: Add skelton for BeBoB based devices')

#1302032 — [PATCH 4.2.y-ckt 125/211] ipv4: Fix ip_local_out_sk by passing the sk into __ip_local_out_sk

4.2.8-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Eric W. Biederman" <ebiederm@xmission.com>

commit fd2874b3bbe832e90ac480971a7a8bd736b629b9 upstream.

In the rare case where sk != skb->sk ip_local_out_sk arranges
to call dst->output differently if the skb is queued or not.
This is a bug.

Fix this bug by passing the sk parameter of ip_local_out_sk through
from ip_local_out_sk to __ip_local_out_sk (skipping __ip_local_out).

4.2.8-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@oracle.com>

commit 1f35d04a02a652f14566f875aef3a6f2af4cb77b upstream.

The iomap[] array has PCIM_IOMAP_MAX (6) elements and not
DEVICE_COUNT_RESOURCE (16).  This bug was found using a static checker.
It may be that the "if (!(mask & (1 << i)))" check means we never
actually go past the end of the array in real life.

4.2.8-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sifan Naeem <sifan.naeem@imgtec.com>

commit 58b0497dad1abbe389af83e3d7706be584cf3ba2 upstream.

The requested bit rate can be outside the range supported by the driver.
The maximum bit rate this driver supports at the moment is 400Khz.

If the requested bit rate is larger than the maximum supported by the
driver, set the bitrate to the maximum supported before bitrate_khz is
calculated.

Maximum speed supported by the driver can be increased to 1Mhz by
adding support for "fast plus mode" in the future.

#1302035 — [PATCH 4.2.y-ckt 138/211] drm: Fix return value of drm_framebuffer_init()

4.2.8-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lukas Wunner <lukas@wunner.de>

commit 3c67d839b30c7d6d6ab5c6fddac0f58ec8095d50 upstream.

In its original version, drm_framebuffer_init() returned a negative int
if drm_mode_object_get() failed (f453ba046074, "DRM: add mode setting
support").

This was accidentally disabled by commit 4b096ac10da0 ("drm: revamp
locking around fb creation/destruction"). Thus, drm_framebuffer_init()
pretends success if drm_mode_object_get() failed.

Reinstate the original behaviour. Also fix erroneous kernel-doc of
drm_mode_object_get().

#1302036 — [PATCH 4.2.y-ckt 100/211] fs, seqfile: always allow oom killer

4.2.8-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Greg Thelen <gthelen@google.com>

commit 0f930902eb8806cff8dcaef9ff9faf3cfa5fd748 upstream.

Since 5cec38ac866b ("fs, seq_file: fallback to vmalloc instead of oom kill
processes") seq_buf_alloc() avoids calling the oom killer for PAGE_SIZE or
smaller allocations; but larger allocations can use the oom killer via
vmalloc().  Thus reads of small files can return ENOMEM, but larger files
use the oom killer to avoid ENOMEM.

The effect of this bug is that reads from /proc and other virtual
filesystems can return ENOMEM instead of the preferred behavior - oom
killing something (possibly the calling process).  I don't know of anyone
except Google who has noticed the issue.

I suspect the fix is more needed in smaller systems where there isn't any
reclaimable memory.  But these seem like the kinds of systems which
probably don't use the oom killer for production situations.

Memory overcommit requires use of the oom killer to select a victim
regardless of file size.

Enable oom killer for small seq_buf_alloc() allocations.

#1302038 — [PATCH 4.2.y-ckt 126/211] ipv4: Fix ip_queue_xmit to pass sk into ip_local_out_sk

4.2.8-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Eric W. Biederman" <ebiederm@xmission.com>

commit 850dcc4d4dd7d5da5c1b2a780c5e649c3b649545 upstream.

After a packet has been encapsulated by a tunnel we should use the
tunnel sockets local multicast loopback flag to control if the
encapsulated packet should be locally loopback back.

Pass sk into ip_local_out_sk so that in the rare case we are dealing
with a tunneled packet whose tunnel destination address is a multicast
address the kernel properly decides to loopback this packet.

In practice I don't think this matters as ip_queue_xmit is used by
tcp, l2tp and sctp none of which I am aware of uses ip level
multicasting as they are all point to point communications protocols.
Let's fix this before someone uses ip_queue_xmit for a tunnel protocol
that does use multicast.

#1302040 — [PATCH 4.2.y-ckt 136/211] regulator: arizona-ldo1: Fix handling of GPIO 0

4.2.8-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Charles Keepax <ckeepax@opensource.wolfsonmicro.com>

commit ce938001c08c6580a8da38dc226fa605512afab6 upstream.

The LDO1 driver is using the arizona_of_get_named_gpio helper function
which will return 0 if an error was encountered whilst parsing the GPIO,
as under the pdata scheme 0 was not being treated as a valid GPIO.
However, since the regulator framework was expanded to allow the use of
GPIO 0 this causes us to attempt to register GPIO 0 when we encountered
an error parsing the device tree.

This patch uses of_get_named_gpio directly and sets the
ena_gpio_initialized flag based on the return value.

#1302042 — [PATCH 4.2.y-ckt 142/211] ALSA: bebob: use correct type for __be32 data

4.2.8-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Takashi Sakamoto <o-takashi@sakamocchi.jp>

commit fef586d58960bc867c1fa8126ee5d7364a5a89ac upstream.

In former commit, metering is supported for BeBoB based models
customized by M-Audio. The data in transaction is aligned to
big-endianness, while in the driver code u16 typed variable is assigned
to the data. This causes sparse warnings.

bebob_maudio.c:651:31: warning: cast to restricted __be16
bebob_maudio.c:651:31: warning: cast to restricted __be16
bebob_maudio.c:651:31: warning: cast to restricted __be16
bebob_maudio.c:651:31: warning: cast to restricted __be16

This commit fixes this bug by using __be16 variable for the data.

4.2.8-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Takashi Sakamoto <o-takashi@sakamocchi.jp>

commit cbc6f28067aa0aa1193c2bf3546430b2c4dae22c upstream.

In former commit, u32 data was assigned to __be32 variable instead of an
int variable. This is not enough solution because it still causes sparse
warnings.

#1302045 — [PATCH 4.2.y-ckt 092/211] mm/oom_kill.c: reverse the order of setting TIF_MEMDIE and sending SIGKILL

4.2.8-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tetsuo Handa <penguin-kernel@i-love.sakura.ne.jp>

commit 426fb5e72d92b868912e47a1e3ca2df6eabc3872 upstream.

It was confirmed that a local unprivileged user can consume all memory
reserves and hang up that system using time lag between the OOM killer
sets TIF_MEMDIE on an OOM victim and sends SIGKILL to that victim, for
printk() inside for_each_process() loop at oom_kill_process() can consume
many seconds when there are many thread groups sharing the same memory.

Before starting oom-depleter process:

    Node 0 DMA: 3*4kB (UM) 6*8kB (U) 4*16kB (UEM) 0*32kB 0*64kB 1*128kB (M) 2*256kB (EM) 2*512kB (UE) 2*1024kB (EM) 1*2048kB (E) 1*4096kB (M) = 9980kB
    Node 0 DMA32: 31*4kB (UEM) 27*8kB (UE) 32*16kB (UE) 13*32kB (UE) 14*64kB (UM) 7*128kB (UM) 8*256kB (UM) 8*512kB (UM) 3*1024kB (U) 4*2048kB (UM) 362*4096kB (UM) = 1503220kB

As of invoking the OOM killer:

    Node 0 DMA: 11*4kB (UE) 8*8kB (UEM) 6*16kB (UE) 2*32kB (EM) 0*64kB 1*128kB (U) 3*256kB (UEM) 2*512kB (UE) 3*1024kB (UEM) 1*2048kB (U) 0*4096kB = 7308kB
    Node 0 DMA32: 1049*4kB (UEM) 507*8kB (UE) 151*16kB (UE) 53*32kB (UEM) 83*64kB (UEM) 52*128kB (EM) 25*256kB (UEM) 11*512kB (M) 6*1024kB (UM) 1*2048kB (M) 0*4096kB = 44556kB

Between the thread group leader got TIF_MEMDIE and receives SIGKILL:

    Node 0 DMA: 0*4kB 0*8kB 0*16kB 0*32kB 0*64kB 0*128kB 0*256kB 0*512kB 0*1024kB 0*2048kB 0*4096kB = 0kB
    Node 0 DMA32: 0*4kB 0*8kB 0*16kB 0*32kB 0*64kB 0*128kB 0*256kB 0*512kB 0*1024kB 0*2048kB 0*4096kB = 0kB

The oom-depleter's thread group leader which got TIF_MEMDIE started
memset() in user space after the OOM killer set TIF_MEMDIE, and it was
free to abuse ALLOC_NO_WATERMARKS by TIF_MEMDIE for memset() in user space
until SIGKILL is delivered.  If SIGKILL is delivered before TIF_MEMDIE is
set, the oom-depleter can terminate without touching memory reserves.

Although the possibility of hitting this time lag is very small for 3.19
and earlier kernels because TIF_MEMDIE is set immediately before sending
SIGKILL, preemption or long interrupts (an extreme example is SysRq-t) can
step between and allow memory allocations which are not needed for
terminating the OOM victim.

#1302047 — [PATCH 4.2.y-ckt 135/211] hsi: omap_ssi_port: Prevent warning if cawake_gpio is not defined.

4.2.8-ckt1 -stable review patch.  If anyone has any objections, please let me know.

From: Roger Quadros <rogerq@ti.com>

commit e74eba049356fdad6713ab66322d9aeb0e85608b upstream.

The error handling path is broken as cawake_gpio was defined as
unsigned integer causing the following warnings on boards that don't
use SSI port and so don't have cawake_gpio defined. e.g. beagleboard C4.

#1302048 — [PATCH 4.2.y-ckt 144/211] tcp: apply Kern's check on RTTs used for congestion control

4.2.8-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Yuchung Cheng <ycheng@google.com>

commit 9e45a3e36b363cc4c79c70f2b4f994e66543a219 upstream.

Currently ca_seq_rtt_us does not use Kern's check. Fix that by
checking if any packet acked is a retransmit, for both RTT used
for RTT estimation and congestion control.

Fixes: 5b08e47ca ("tcp: prefer packet timing to TS-ECR for RTT")
