Subject: [PATCH 06/32] CGTS-3744: route: do not cache fib route info on local
routes with oif
For local routes that require a particular output interface we do not want to
cache the result. Caching the result causes incorrect behaviour when there are
multiple source addresses on the interface. The end result being that if the
intended recipient is waiting on that interface for the packet he won't receive
it because it will be delivered on the loopback interface and the IP_PKTINFO
ipi_ifindex will be set to the loopback interface as well.
This can be tested by running a program such as "dhcp_release" which attempts
to inject a packet on a particular interface so that it is received by another
program on the same board. The receiving process should see an IP_PKTINFO
ipi_ifndex value of the source interface (e.g., eth1) instead of the loopback
interface (e.g., lo). The packet will still appear on the loopback interface
in tcpdump but the important aspect is that the CMSG info is correct.
Sample dhcp_release command line:
dhcp_release eth1 192.168.204.222 02:11:33:22:44:66

Subject: [PATCH] CPU / PM: expose pm_qos_resume_latency for CPUs
[ commit 37efa4b41ffb31dcdfc3beb97d47992bb2a083e5 from linux-stable ]
The cpu-dma PM QoS constraint impacts all the cpus in the system. There is no way
to let the user to choose a PM QoS constraint per cpu.
The following patch exposes to the userspace a per cpu based sysfs file
in order to let the userspace to change the value of the PM QoS latency
constraint.
This change is inoperative in its form and the cpuidle governors have to
take into account the per cpu latency constraint in addition to the
global cpu-dma latency constraint in order to operate properly.
BTW
The pm_qos_resume_latency usage defined in
Documentation/ABI/testing/sysfs-devices-power
The /sys/devices/.../power/pm_qos_resume_latency_us attribute
contains the PM QoS resume latency limit for the given device,
which is the maximum allowed time it can take to resume the
device, after it has been suspended at run time, from a resume
request to the moment the device will be ready to process I/O,
in microseconds. If it is equal to 0, however, this means that
the PM QoS resume latency may be arbitrary.

Subject: [PATCH 16/32] Enable building kernel with CONFIG_BLK_DEV_NBD
By default, the CentOS 7.3 kernel will fail to build if
CONFIG_BLK_DEV_NBD is enabled, either as module or builtin.
The issue seems to be due to the use of REQ_TYPE_SPECIAL in the
NBD code. Switching it to use REQ_TYPE_DRV_PRIV instead makes the
problem go away.

Had to revert commit 7cc277b489b4fe91f42eb596b282879c2d13152e:
"Install the callbacks via the state machine and let the core invoke
the callbacks on the already online CPUs. No functional change."
There is no hotplug state machine in 3.10 kernel.
Also implemented cpumap_print_to_pagebuf() function in place.

will let us rename to a range starting at eth0.

Subject: [PATCH 25/32] US101216: IMA support in Titanium kernel
facilitate building the IMA subsytem out-of-the-kernel tree as a Kernel
module (for which CONFIG_IMA and CONFIG_INTEGRITY will be undefined) by:
- exporting certain function symbols which will be linked to the kernel
module. This includes redefining the export symbols for kernel
functions such that when the kernel module loads, it dynamically points
to those new function definations and reverts to Kernel default
definitions on module deinit
- enabling inode readcount
- modification to ima_file_check to pass in file OPEN status

Subject: [PATCH 26/32] US103091: IMA: System Configuration
Normally (if trusted integrity keyring is disabled), the _ima keyring
needs to be created by user space (specifically systemd), but that has
the added disadvantage of requiring the IMA public key to reside on the
file system as opposed to being compiled in. Somebody could render some
serious Grade A damage by corrupting this public key on the FS.
Crippling the system if IMA 'enforce' action is enabled.
We will therefore create the IMA keyring inside the kernel and load the
IMA public key as a compiled data blob, similar to how the Kernel loads
trusted X509 keys into the system truststore (.system_keyring)

Subject: [PATCH 29/32] aic94xx: Skip reading user settings if flash is not
found
If no user settings are found it's pointless trying to
read them from flash. So skip that step.
This also fixes a compilation warning about uninitialized variables in
aic94xx.

Subject: [PATCH 07/32] cma: add placement specifier for "cma=" kernel
parameter
Commit 5ea3b1b2f8ad9162684431ce6188102ca4c64b7a upstream
Backported-by: Nam Ninh <nam.ninh@windriver.com>
Currently, "cma=" kernel parameter is used to specify the size of CMA,
but we can't specify where it is located. We want to locate CMA below
4GB for devices only supporting 32-bit addressing on 64-bit systems
without iommu.
This enables to specify the placement of CMA by extending "cma=" kernel
parameter.
Examples:
1. locate 64MB CMA below 4GB by "cma=64M@0-4G"
2. locate 64MB CMA exact at 512MB by "cma=64M@512M"
Note that the DMA contiguous memory allocator on x86 assumes that
page_address() works for the pages to allocate. So this change requires
to limit end address of contiguous memory area upto max_pfn_mapped to
prevent from locating it on highmem area by the argument of
dma_contiguous_reserve().

Subject: [PATCH 24/32] cpuidle: menu: Avoid taking spinlock for accessing QoS
values
[commit 6dbf5cea05a7098a69f294c96b6d76f08562cae5 from linux-stable ]
After commit 9908859acaa9 (cpuidle/menu: add per CPU PM QoS resume
latency consideration) the cpuidle menu governor calls
dev_pm_qos_read_value() on CPU devices to read the current resume latency QoS
constraint values for them. That function takes a spinlock to prevent the
device's power.qos pointer from becoming NULL during the access which is a
problem for the RT patchset where spinlocks are converted into mutexes and
the idle loop stops working.
However, it is not even necessary for the menu governor to take
that spinlock, because the power.qos pointer accessed under it
cannot be modified during the access anyway.
For this reason, introduce a "raw" routine for accessing device
QoS resume latency constraints without locking and use it in the
menu governor.
Fixes: 9908859acaa9 (cpuidle/menu: add per CPU PM QoS resume latency consideration)

Subject: [PATCH 22/32] cpuidle/menu: add per CPU PM QoS resume latency
consideration
[ commit 9908859acaa95640d4a07991a93f7cd5bfc18e02 from linux-stable ]
There may be special requirements on CPU response time, like if
a interrupt is pinned to a CPU, that CPU should not go into excessively deep
idle states. For this reason, add a mechanism for adding PM QoS resume
latency constraints for individual CPUs and modify the menu governor to take
them into account.
To that end, extend the device PM QoS pm_qos_resume_latency attribute
to CPUs, which is possible, because the exit latency for CPUs is
effectively equivalent to the resume latency for devices.

Subject: [PATCH 21/32] cpuidle/menu: stop seeking deeper idle if current state
is deep enough
[ commit 8e37e1a2a3295f5d99e6dbe99eca24eca7a034ef from linux-stable ]
Obsolete commit 71abbbf856a0 (cpuidle: extend cpuidle and menu
governor to handle dynamic states) wanted to introduce dynamic C-states, but
that idea was dropped long ago. The nonsense deeper C-state checking
remained, though.
Since both target_residency and exit_latency are longer for deeper
idle state, there's no need to waste CPU time on useless checks.

Subject: [PATCH] epoll: fix use-after-free in eventpoll_release_file
This fixes use-after-free of epi->fllink.next inside list loop macro.
This loop actually releases elements in the body. The list is
rcu-protected but here we cannot hold rcu_read_lock because we need to
lock mutex inside.
The obvious solution is to use list_for_each_entry_safe(). RCU-ness
isn't essential because nobody can change this list under us, it's final
fput for this file.
The bug was introduced by ae10b2b4eb01 ("epoll: optimize EPOLL_CTL_DEL
using rcu")

Subject: [PATCH 10/32] memblock: introduce memblock_alloc_range()
Commit 2bfc2862c4fe38379a2fb2cfba33fad32ccb4ff4 upstream
Backported-by: Nam Ninh <nam.ninh@windriver.com>
This introduces memblock_alloc_range() which allocates memblock from the
specified range of physical address. I would like to use this function
to specify the location of CMA.

Subject: [PATCH 2/3] rh/ext4: release leaked posix acl in ext4_acl_chmod
[ commit b85d6be0b743a1768b8456d36b52960858fbaa67 in OpenVZ's vzkernel repo ]
Note: only rh7-3.10.0-693.17.1.el7-based kernels are affected.
I.e. starting from rh7-3.10.0-693.17.1.vz7.43.1.
Posix acl is used to convert of an extended attribute, provided by user to ext4
attributes. In particular to i_mode in case of ACL_TYPE_ACCESS request.
IOW, this object is allocated, used for convertion, not stored anywhere and
must be freed.
However posix_acl_update_mode() can zerofy the pointer to support
ext4_set_acl() logic, but then the object is leaked. So, fix it by releasing
new temporary pointer with the same value instead of acl pointer.

From c0ad4aa4d8416a39ad262a2bd68b30acd951bf0e Mon Sep 17 00:00:00 2001
From: Peter Zijlstra <peterz@infradead.org>

Subject: sched/fair: Robustify CFS-bandwidth timer locking
Traditionally hrtimer callbacks were run with IRQs disabled, but with
the introduction of HRTIMER_MODE_SOFT it is possible they run from
SoftIRQ context, which does _NOT_ have IRQs disabled.
Allow for the CFS bandwidth timers (period_timer and slack_timer) to
be ran from SoftIRQ context; this entails removing the assumption that
IRQs are already disabled from the locking.
While mainline doesn't strictly need this, -RT forces all timers not
explicitly marked with MODE_HARD into MODE_SOFT and trips over this.
And marking these timers as MODE_HARD doesn't make sense as they're
not required for RT operation and can potentially be quite expensive.

Subject: [PATCH 13/32] x86: enable DMA CMA with swiotlb
commit 9c5a3621427da68afe6a078cadf807d2c8cc1d12 upstream.
Ported-by: Nam Ninh <nam.ninh@windriver.com>
The DMA Contiguous Memory Allocator support on x86 is disabled when
swiotlb config option is enabled. So DMA CMA is always disabled on
x86_64 because swiotlb is always enabled. This attempts to support for
DMA CMA with enabling swiotlb config option.
The contiguous memory allocator on x86 is integrated in the function
dma_generic_alloc_coherent() which is .alloc callback in nommu_dma_ops
for dma_alloc_coherent().
x86_swiotlb_alloc_coherent() which is .alloc callback in swiotlb_dma_ops
tries to allocate with dma_generic_alloc_coherent() firstly and then
swiotlb_alloc_coherent() is called as a fallback.
The main part of supporting DMA CMA with swiotlb is that changing
x86_swiotlb_free_coherent() which is .free callback in swiotlb_dma_ops
for dma_free_coherent() so that it can distinguish memory allocated by
dma_generic_alloc_coherent() from one allocated by
swiotlb_alloc_coherent() and release it with dma_generic_free_coherent()
which can handle contiguous memory. This change requires making
is_swiotlb_buffer() global function.
This also needs to change .free callback in the dma_map_ops for amd_gart
and sta2x11, because these dma_ops are also using
dma_generic_alloc_coherent().

Subject: [PATCH 17/32] x86: make dma_alloc_coherent() return zeroed memory if
CMA is enabled
This patchset enhances the DMA Contiguous Memory Allocator on x86.
Currently the DMA CMA is only supported with pci-nommu dma_map_ops and
furthermore it can't be enabled on x86_64. But I would like to allocate
big contiguous memory with dma_alloc_coherent() and tell it to the device
that requires it, regardless of which dma mapping implementation is
actually used in the system.
So this makes it work with swiotlb and intel-iommu dma_map_ops, too. And
this also extends "cma=" kernel parameter to specify placement constraint
by the physical address range of memory allocations. For example, CMA
allocates memory below 4GB by "cma=64M@0-4G", it is required for the
devices only supporting 32-bit addressing on 64-bit systems without iommu.
This patch (of 5):
Calling dma_alloc_coherent() with __GFP_ZERO must return zeroed memory.
But when the contiguous memory allocator (CMA) is enabled on x86 and the
memory region is allocated by dma_alloc_from_contiguous(), it doesn't
return zeroed memory. Because dma_generic_alloc_coherent() forgot to fill
the memory region with zero if it was allocated by
dma_alloc_from_contiguous()
Most implementations of dma_alloc_coherent() return zeroed memory
regardless of whether __GFP_ZERO is specified. So this fixes it by
unconditionally zeroing the allocated memory region.
Alternatively, we could fix dma_alloc_from_contiguous() to return zeroed
out memory and remove memset() from all caller of it. But we can't simply
remove the memset on arm because __dma_clear_buffer() is used there for
ensuring cache flushing and it is used in many places. Of course we can
do redundant memset in dma_alloc_from_contiguous(), but I think this patch
is less impact for fixing this problem.
