From: Ben Hutchings <ben@decadent.org.uk>
Date: Sat, 14 Dec 2013 17:14:39 +0000
Subject: firmware_class: Return specific errors from file read
Forwarded: no
Currently several failure cases are not distinguished and are
incorrectly reported as -EINVAL or -ENOENT.
Change fw_file_size() to return an error code on failure and
adjust fw_read_file_contents() and fw_get_filesystem_firmware()
Change _request_firmware() to return the error code from
fw_get_filesystem_firmware() if CONFIG_FW_LOADER_USER_HELPER is not
enabled. (If it is enabled and also fails, unfortunately we can't
tell why.)

Subject: ipv4: Don't do expensive useless work during inetdev destroy.
Origin: https://git.kernel.org/linus/fbd40ea0180a2d328c5adc61414dc8bab9335ce2
When an inetdev is destroyed, every address assigned to the interface
is removed. And in this scenerio we do two pointless things which can
be very expensive if the number of assigned interfaces is large:
1) Address promotion. We are deleting all addresses, so there is no
point in doing this.
2) A full nf conntrack table purge for every address. We only need to
do this once, as is already caught by the existing
masq_dev_notifier so masq_inet_event() can skip this.

Forwarded: http://thread.gmane.org/gmane.linux.kernel/1514281
Commit 985087dbcb02 'misc: add support for bmp18x chips to the bmp085
driver' changed the BMP085 config symbol to a boolean. I see no
reason why the shared code cannot be built as a module, so change it
back to tristate.

Subject: mm: ZONE_DEVICE depends on SPARSEMEM_VMEMMAP
Origin: http://article.gmane.org/gmane.linux.kernel.mm/147702
The primary use case for devm_memremap_pages() is to allocate an memmap
array from persistent memory. That capabilty requires vmem_altmap which
requires SPARSEMEM_VMEMMAP.
Also, without SPARSEMEM_VMEMMAP the addition of ZONE_DEVICE expands
ZONES_WIDTH and triggers the:
"Unfortunate NUMA and NUMA Balancing config, growing page-frame for
last_cpupid."
...warning in mm/memory.c. SPARSEMEM_VMEMMAP=n && ZONE_DEVICE=y is not
a configuration we should worry about supporting.

Subject: ACPI / processor: Request native thermal interrupt handling via _OSC
Origin: https://git.kernel.org/linus/a21211672c9a1d730a39aa65d4a5b3414700adfb
Bug-Debian: https://bugs.debian.org/817016
There are several reports of freeze on enabling HWP (Hardware PStates)
feature on Skylake-based systems by the Intel P-states driver. The root
cause is identified as the HWP interrupts causing BIOS code to freeze.
HWP interrupts use the thermal LVT which can be handled by Linux
natively, but on the affected Skylake-based systems SMM will respond
to it by default. This is a problem for several reasons:
- On the affected systems the SMM thermal LVT handler is broken (it
will crash when invoked) and a BIOS update is necessary to fix it.
- With thermal interrupt handled in SMM we lose all of the reporting
features of the arch/x86/kernel/cpu/mcheck/therm_throt driver.
- Some thermal drivers like x86-package-temp depend on the thermal
threshold interrupts signaled via the thermal LVT.
- The HWP interrupts are useful for debugging and tuning
performance (if the kernel can handle them).
The native handling of thermal interrupts needs to be enabled
because of that.
This requires some way to tell SMM that the OS can handle thermal
interrupts. That can be done by using _OSC/_PDC in processor
scope very early during ACPI initialization.
The meaning of _OSC/_PDC bit 12 in processor scope is whether or
not the OS supports native handling of interrupts for Collaborative
Processor Performance Control (CPPC) notifications. Since on
HWP-capable systems CPPC is a firmware interface to HWP, setting
this bit effectively tells the firmware that the OS will handle
thermal interrupts natively going forward.
For details on _OSC/_PDC refer to:
http://www.intel.com/content/www/us/en/standards/processor-vendor-specific-acpi-specification.html
To implement the _OSC/_PDC handshake as described, introduce a new
function, acpi_early_processor_osc(), that walks the ACPI
namespace looking for ACPI processor objects and invokes _OSC for
them with bit 12 in the capabilities buffer set and terminates the
namespace walk on the first success.
Also modify intel_thermal_interrupt() to clear HWP status bits in
the HWP_STATUS MSR to acknowledge HWP interrupts (which prevents
them from firing continuously).

A recent bug fix rearranged the code in vmxnet3_tq_xmit() in a
way that left the error handling for oversized headers unlock
a lock that had not been taken yet. Gcc warns about the incorrect
use of the 'flags' variable because of that:
drivers/net/vmxnet3/vmxnet3_drv.c: In function 'vmxnet3_tq_xmit.constprop':
include/linux/spinlock.h:246:3: error: 'flags' may be used uninitialized in this function [-Werror=maybe-uninitialized]
This changes the error handling path to 'goto' the end of the function
beyond the lock/unlock pair.

Bug-Debian: https://bugs.debian.org/815125
Starting with this commit 35eb8b81edd4 ("x86/efi: Build our own page
table structures") efi regions have a separate page directory called
"efi_pgd". In order to access any efi region we have to first shift %cr3
to this page table. In the bgrt code we are trying to copy bgrt_header
and image, but these regions fall under "EFI_BOOT_SERVICES_DATA"
and to access these regions we have to shift %cr3 to efi_pgd and not
doing so will cause page fault as shown below.

As said above one way to fix this bug is to shift %cr3 to efi_pgd but we
are not doing that way because it leaks inner details of how we switch
to EFI page tables into a new call site and it also adds duplicate code.
Instead, we remove the call to efi_lookup_mapped_addr() and always
perform early_mem*() instead of early_io*() because we want to remap RAM
regions and not I/O regions. We also delete efi_lookup_mapped_addr()
because we are no longer using it.

[ 0.026978] efi_bgrt: Ignoring BGRT: failed to map image memory
early_memremap() has an upper limit on the size of mapping it can
handle which is ~200KB. Clearly the BGRT image on Môshe's machine is
much larger than that.
There's actually no reason to restrict ourselves to using the early_*
version of memremap() - the ACPI BGRT driver is invoked late enough in
boot that we can use the standard version, with the benefit that the
late version allows mappings of arbitrary size.

Subject: [5/5] x86/efi: Build our own page table structures
Origin: https://git.kernel.org/cgit/linux/kernel/git/mfleming/efi.git/commit?id=67a9108ed4313b85a9c53406d80dc1ae3f8c3e36
With commit e1a58320a38d ("x86/mm: Warn on W^X mappings") all
users booting on 64-bit UEFI machines see the following warning,
------------[ cut here ]------------
WARNING: CPU: 7 PID: 1 at arch/x86/mm/dump_pagetables.c:225 note_page+0x5dc/0x780()
x86/mm: Found insecure W+X mapping at address ffff88000005f000/0xffff88000005f000
...
x86/mm: Checked W+X mappings: FAILED, 165660 W+X pages found.
...
This is caused by mapping EFI regions with RWX permissions.
There isn't much we can do to restrict the permissions for these
regions due to the way the firmware toolchains mix code and
data, but we can at least isolate these mappings so that they do
not appear in the regular kernel page tables.
In commit d2f7cbe7b26a ("x86/efi: Runtime services virtual
mapping") we started using 'trampoline_pgd' to map the EFI
regions because there was an existing identity mapping there
which we use during the SetVirtualAddressMap() call and for
broken firmware that accesses those addresses.
But 'trampoline_pgd' shares some PGD entries with
'swapper_pg_dir' and does not provide the isolation we require.
Notably the virtual address for __START_KERNEL_map and
MODULES_START are mapped by the same PGD entry so we need to be
more careful when copying changes over in
efi_sync_low_kernel_mappings().
This patch doesn't go the full mile, we still want to share some
PGD entries with 'swapper_pg_dir'. Having completely separate
page tables brings its own issues such as synchronising new
mappings after memory hotplug and module loading. Sharing also
keeps memory usage down.

Subject: [4/5] x86/efi: Hoist page table switching code into efi_call_virt()
Origin: https://git.kernel.org/cgit/linux/kernel/git/mfleming/efi.git/commit?id=c9f2a9a65e4855b74d92cdad688f6ee4a1a323ff
This change is a prerequisite for pending patches that switch to
a dedicated EFI page table, instead of using 'trampoline_pgd'
which shares PGD entries with 'swapper_pg_dir'. The pending
patches make it impossible to dereference the runtime service
function pointer without first switching %cr3.
It's true that we now have duplicated switching code in
efi_call_virt() and efi_call_phys_{prolog,epilog}() but we are
sacrificing code duplication for a little more clarity and the
ease of writing the page table switching code in C instead of
asm.

Subject: [3/5] x86/efi: Map RAM into the identity page table for mixed mode
Origin: https://git.kernel.org/cgit/linux/kernel/git/mfleming/efi.git/commit?id=b61a76f8850d2979550abc42d7e09154ebb8d785
We are relying on the pre-existing mappings in 'trampoline_pgd'
when accessing function arguments in the EFI mixed mode thunking
code.
Instead let's map memory explicitly so that things will continue
to work when we move to a separate page table in the future.

Subject: x86/efi: Setup separate EFI page tables in kexec paths
Origin: https://git.kernel.org/cgit/linux/kernel/git/mfleming/efi.git/commit?id=753b11ef8e92a1c1bbe97f2a5ec14bdd1ef2e6fe
The switch to using a new dedicated page table for EFI runtime
calls in commit commit 67a9108ed431 ("x86/efi: Build our own
page table structures") failed to take into account changes
required for the kexec code paths, which are unfortunately
duplicated in the EFI code.
Call the allocation and setup functions in
kexec_enter_virtual_mode() just like we do for
__efi_enter_virtual_mode() to avoid hitting NULL-pointer
dereferences when making EFI runtime calls.
At the very least, the call to efi_setup_page_tables() should
have existed for kexec before the following commit:
67a9108ed431 ("x86/efi: Build our own page table structures")
Things just magically worked because we were actually using
the kernel's page tables that contained the required mappings.

Subject: x86/mm/32: Enable full randomization on i386 and X86_32
Origin: https://git.kernel.org/linus/8b8addf891de8a00e4d39fc32f93f7c5eb8feceb
Currently on i386 and on X86_64 when emulating X86_32 in legacy mode, only
the stack and the executable are randomized but not other mmapped files
(libraries, vDSO, etc.). This patch enables randomization for the
libraries, vDSO and mmap requests on i386 and in X86_32 in legacy mode.
By default on i386 there are 8 bits for the randomization of the libraries,
vDSO and mmaps which only uses 1MB of VA.
This patch preserves the original randomness, using 1MB of VA out of 3GB or
4GB. We think that 1MB out of 3GB is not a big cost for having the ASLR.
The first obvious security benefit is that all objects are randomized (not
only the stack and the executable) in legacy mode which highly increases
the ASLR effectiveness, otherwise the attackers may use these
non-randomized areas. But also sensitive setuid/setgid applications are
more secure because currently, attackers can disable the randomization of
these applications by setting the ulimit stack to "unlimited". This is a
very old and widely known trick to disable the ASLR in i386 which has been
allowed for too long.
Another trick used to disable the ASLR was to set the ADDR_NO_RANDOMIZE
personality flag, but fortunately this doesn't work on setuid/setgid
applications because there is security checks which clear Security-relevant
flags.
This patch always randomizes the mmap_legacy_base address, removing the
possibility to disable the ASLR by setting the stack to "unlimited".

Subject: [1/5] x86/mm: Page align the '_end' symbol to avoid pfn conversion
bugs
Origin: https://git.kernel.org/cgit/linux/kernel/git/mfleming/efi.git/commit?id=21cdb6b568435738cc0b303b2b3b82742396310c
Ingo noted that if we can guarantee _end is aligned to PAGE_SIZE
we can automatically avoid bugs along the lines of,
size = _end - _text >> PAGE_SHIFT
which is missing a call to PFN_ALIGN(). The EFI mixed mode
contains this bug, for example.
_text is already aligned to PAGE_SIZE through the use of
LOAD_PHYSICAL_ADDR, and the BSS and BRK sections are explicitly
aligned in the linker script, so it makes sense to align _end to
match.

Subject: [2/5] x86/mm/pat: Ensure cpa->pfn only contains page frame numbers
Origin: https://git.kernel.org/cgit/linux/kernel/git/mfleming/efi.git/commit?id=edc3b9129cecd0f0857112136f5b8b1bc1d45918
The x86 pageattr code is confused about the data that is stored
in cpa->pfn, sometimes it's treated as a page frame number,
sometimes it's treated as an unshifted physical address, and in
one place it's treated as a pte.
The result of this is that the mapping functions do not map the
intended physical address.
This isn't a problem in practice because most of the addresses
we're mapping in the EFI code paths are already mapped in
'trampoline_pgd' and so the pageattr mapping functions don't
actually do anything in this case. But when we move to using a
separate page table for the EFI runtime this will be an issue.

Subject: x86/mm/pat: Fix boot crash when 1GB pages are not supported by cpu
Origin: http://mid.gmane.org/1457951581-27353-2-git-send-email-matt@codeblueprint.co.uk
Scott reports that with the new separate EFI page tables he's seeing
the following error on boot, caused by setting reserved bits in the
page table structures (fault code is PF_RSVD | PF_PROT),
swapper/0: Corrupted page table at address 17b102020
PGD 17b0e5063 PUD 1400000e3
Bad pagetable: 0009 [#1] SMP
On first inspection the PUD is using a 1GB page size (_PAGE_PSE) and
looks fine but that's only true if support for 1GB PUD pages
("pdpe1gb") is present in the cpu.
Scott's Intel Celeron N2820 does not have that feature and so the
_PAGE_PSE bit is reserved. Fix this issue by making the 1GB mapping
code in conditional on "cpu_has_gbpages".
This issue didn't come up in the past because the required mapping for
the faulting address (0x17b102020) will already have been setup by the
kernel in early boot before we got to efi_map_regions(), but we no
longer use the standard kernel page tables during EFI calls.

Subject: mm: exclude ZONE_DEVICE from GFP_ZONE_TABLE
Origin: http://article.gmane.org/gmane.linux.kernel.mm/147399
ZONE_DEVICE (merged in 4.3) and ZONE_CMA (proposed) are examples of new mm
zones that are bumping up against the current maximum limit of 4 zones,
i.e. 2 bits in page->flags for the GFP_ZONE_TABLE.
The GFP_ZONE_TABLE poses an interesting constraint since
include/linux/gfp.h gets included by the 32-bit portion of a 64-bit build.
We need to be careful to only build the table for zones that have a
corresponding gfp_t flag. GFP_ZONES_SHIFT is introduced for this purpose.
This patch does not attempt to solve the problem of adding a new zone
that also has a corresponding GFP_ flag.
Vlastimil points out that ZONE_DEVICE, by depending on x86_64 and
SPARSEMEM_VMEMMAP implies that SECTIONS_WIDTH is zero. In other words
even though ZONE_DEVICE does not fit in GFP_ZONE_TABLE it is free to
consume another bit in page->flags (expand ZONES_WIDTH) with room to
spare.

Subject: nbd: Create size change events for userspace
Origin: https://git.kernel.org/linus/37091fdd831f28a6509008542174ed324dd645bc
Bug-Debian: https://bugs.debian.org/812487
The userspace needs to know when nbd devices are ready for use.
Currently no events are created for the userspace which doesn't work for
systemd.
See the discussion here: https://github.com/systemd/systemd/pull/358
This patch uses a central point to setup the nbd-internal sizes. A ioctl
to set a size does not lead to a visible size change. The size of the
block device will be kept at 0 until nbd is connected. As soon as it
connects, the size will be changed to the real value and a uevent is
created. When disconnecting, the blockdevice is set to 0 size and
another uevent is generated.

Origin: https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=ee10774a9b48e8785f1426e273059c4ba038a27f
Bug-Debian: https://bugs.debian.org/813881
Downstream packages like Debian flash-kernel use
/proc/device-tree/model
to determine which dtb file to install.
Hence each dts in the Linux kernel should provide a unique model
identifier.
Commit 8536239e371f ("ARM: dts: Restructure imx6qdl-wandboard.dtsi for new
rev C1 board.")' created new files imx6dl-wandboard-revb1.dts and
imx6q-wandboard-revb1.dts but used the same model identifier as in
imx6dl-wandboard.dts and imx6q-wandboard.dts.
This patch provides unique model identifiers for revision B1 of
the Wandboard Dual and Wandbaord Quad.
The patch leaves imx6dl-wandboard.dts and imx6q-wandboard.dts unchanged
because it is not foreseeable if the same dts will valid for future
board revisions or not. Furthermore we should avoid unnecessary
changes.

Subject: ARM: dts: kirkwood: split lswvl dts to linkstation lsvl and lswvl
Origin: https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=60ff189ca05dedac97af8d9e51c285a44bc9e5a5
LS-WVL/VL are both kirkwood-6282 based NAS devices, which share
many MPP pins. However they are slightly different:
- LS-WVL is 2-Bay NAS, and LS-VL is only 1-Bay.
- There're two red LED indicator on LS-WVL to show when HDD fails,
which is similar to LS-WXL, but there's no such on LS-VL.
So after the split, common part goes into .dtsi file:
- kirkwood-linkstation-6282.dtsi
while all rest part goes into device specific .dts file:
- kirkwood-linkstation-lsvl.dts
- kirkwood-linkstation-lswvl.dts

Subject: ARM: dts: kirkwood: split lswxl dts to linkstation lswsxl and lswxl
Origin: https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=b05465ff5b5e90d6d25d3f6c4e8ac6b2b3159435
LS-WXL/WSXL are both kirkwood-6281 based 2-Bay NAS devices, which share
many MPP pins. However they are slightly different:
- There're two red LED indicator on LS-WXL to show when HDD fails,
but there's no such on LS-WSXL.
- There's 4-level speed adjustable FAN on LS-WXL, but not LS-WSXL.
So after the split, common part goes into .dtsi file:
- kirkwood-linkstation.dtsi
- kirkwood-linkstation-duo-6281.dtsi
while all rest part goes into device specific .dts file:
- kirkwood-linkstation-lswsxl.dts
- kirkwood-linkstation-lswxl.dts

Subject: ARM: dts: orion5x: add device tree for buffalo linkstation ls-gl
Origin: https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=b1742ffa9ddb347a8bcb8e5f7dcf4d3a790f9041
Add dts file to support Buffalo Linkstation LS-GL
(a.k.a Buffalo Linkstation Pro/Live), which is marvell orion5x based
3.5" HDD NAS.
Product info:
- (JPN) http://buffalo.jp/products/catalog/item/l/ls-gl/
- (ENG) http://www.buffalotech.com/products/network-storage/linkstation/linkstation-pro
This device tree is based on the board file:
arch/arm/mach-orion5x/kurobox_pro-setup.c
However, that board file also support Kurobox Pro, which is not supported by
device tree yet. So the board file is not removed.

Subject: ARM: dts: orion5x: split linkstation lswtgl into common and device parts
Origin: https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=305e0b2a7a85e8bd65818cb3636b205f784ed377
In order to support more linkstation devices, common part of current
.dts file goes into .dtsi file. Some .dtsi start with "mvebu-" prefix
because other kirkwood based linkstation devices are similar, and
will be migrated to use these .dtsi some time later.
- orion5x-linkstation.dtsi
- mvebu-linkstation-fan.dtsi
- mvebu-linkstation-gpio-simple.dtsi
while all rest part remains in device specific .dts file:
- orion5x-linkstation-lswtgl.dts

+* UCTL SATA controller glue
+
+UCTL is the bridge unit between the I/O interconnect (an internal bus)
+and the SATA AHCI host controller (UAHC). It performs the following functions:
+ - provides interfaces for the applications to access the UAHC AHCI
+ registers on the CN71XX I/O space.
+ - provides a bridge for UAHC to fetch AHCI command table entries and data
+ buffers from Level 2 Cache.
+ - posts interrupts to the CIU.
+ - contains registers that:
+ - control the behavior of the UAHC
+ - control the clock/reset generation to UAHC
+ - control endian swapping for all UAHC registers and DMA accesses
+
+Properties:
+
+- compatible: "cavium,octeon-7130-sata-uctl"
+
+ Compatibility with the cn7130 SOC.
+
+- reg: The base address of the UCTL register bank.
+
+- #address-cells, #size-cells, ranges and dma-ranges must be present and hold
+ suitable values to map all child nodes.
+
+Example:
+
+ uctl@118006c000000 {
+ compatible = "cavium,octeon-7130-sata-uctl";
+ reg = <0x11800 0x6c000000 0x0 0x100>;
+ ranges; /* Direct mapping */
+ dma-ranges;
+ #address-cells = <2>;
+ #size-cells = <2>;
+
+ sata: sata@16c0000000000 {
+ compatible = "cavium,octeon-7130-ahci";
+ reg = <0x16c00 0x00000000 0x0 0x200>;
+ interrupt-parent = <&cibsata>;
+ interrupts = <2 4>; /* Bit: 2, level */
