parisc/signal: Add FPE_CONDTRAP for conditional trap handling
Posix and common sense requires that SI_USER not be a signal specific si_code. Thus add a new FPE_CONDTRAP si_code for conditional traps. Signed-off-by: Helge Deller <deller@gmx.de> Cc: Stephen Rothwell <sfr@canb.auug.org.au> |

The big ticket items are:
- support for rbd "fancy" striping (myself). The striping feature bit
is now fully implemented, allowing mapping v2 images with non-default
striping patterns. This completes support for --image-format 2.
- CephFS quota support (Luis Henriques and Zheng Yan). This set is
based on the new SnapRealm code in the upcoming v13.y.z ("Mimic")
release. Quota handling will be rejected on older filesystems.
- memory usage improvements in CephFS (Chengguang Xu). Directory
specific bits have been split out of ceph_file_info and some effort
went into improving cap reservation code to avoid OOM crashes.
Also included a bunch of assorted fixes all over the place from
Chengguang and others.

platform-drivers-x86 for v4.17-1
Dell SMBIOS driver fixed against memory leaks. The fujitsu-laptop driver is cleaned up and now supports hotkeys for Lifebook U7x7 models. Besides that the typo introduced by one of previous clean up series has been fixed. Specific to x86-based laptops HID device now supports KEY_ROTATE_LOCK_TOGGLE event which is emitted, for example, by Wacom MobileStudio Pro 13. Turbo MAX 3 technology is enabled for the rest of platforms that support Hardware-P-States feature which have core priority described by ACPI CPPC table. Mellanox on x86 gets better support of I2C bus in use including support of hotpluggable ones. Silead touchscreen is enabled on two tablet models, i.e Yours Y8W81 and I.T.Works TW701. From now on the second fan on Thinkpad P50 is supported. The topstar-laptop driver is reworked to support new models, in particular Topstar U931. Some of the changes had been already applied during v4.16 cycle and thus have a duplication here: - 027d50ccd6a01c6ca8969b49e69f26d64a8f94b2 platform/x86: intel-vbtn: Only activate tablet mode switch on 2-in-1's - 250b044e1a584887c06e6ba79446e523ffa3cc9c platform/x86: intel-vbtn: Reset wakeup capable flag on removal - 356b57752c91cffb35356abe6647065bf0edcad1 platform/x86: intel-hid: Reset wakeup capable flag on removal - 501f7e52de8a7b910154740958ce8d902258bf72 platform/x86: wmi: Fix misuse of vsprintf extension %pULL - 98c76a3904261a7b7612821de8b99f0e3b41677c platform/x86: dell-smbios: Correct some style warnings - ec34fe385984b447f62ef6763638874e6fbd1f43 platform/x86: dell-smbios: Rename dell-smbios source to dell-smbios-bae - 41e36f2f85af758fd2f4be76112ebe649d07a801 platform/x86: dell-smbios: Link all dell-smbios-* modules together - c715e4345581bdb475ae4fb378a243aee72579ba platform/x86: Allow for SMBIOS backend defaults - cc69c88fbeb915447b87e5179378d899d1f61554 platform/x86: dell-smbios: Resolve dependency error on DCDBAS - 4716007c23abeb0e42015786794539454aff487b platform/x86: dell-smbios: Resolve dependency error on ACPI_WMI - 7129707ec2356ef9ef9cce469ad14eb37fbbe67e platform/x86: Fix dell driver init order The following is an automated git shortlog grouped by driver: dell-smbios: - Fix memory leaks in build_tokens_sysfs() - Fix dell driver init order - Resolve dependency error on ACPI_WMI - Resolve dependency error on DCDBAS - Allow for SMBIOS backend defaults - Link all dell-smbios-* modules together - Rename dell-smbios source to dell-smbios-base - Correct some style warnings fujitsu-laptop: - Support Lifebook U7x7 hotkeys - Revert UNSUPPORTED_CMD back to an int - Clean up constants - Define constants for backlight power control - Do not include linux/slab.h - Clearly distinguish module parameters - Simplify error paths - Defer input device registration - Unify local variable naming GPD pocket fan: - fix spelling mistake: "Mill-celcius" -> "millicelsius" intel-hid: - support KEY_ROTATE_LOCK_TOGGLE - clean up and sort header files - Reset wakeup capable flag on removal intel_turbo_max_3: - Remove restriction for HWP platforms intel-vbtn: - Reset wakeup capable flag on removal - Only activate tablet mode switch on 2-in-1's mlx-platform: - Add physical bus number auto detection - Add deffered bus functionality - Use define for the channel numbers platform/mellanox: - mlxreg-hotplug: Change input for device create routine silead_dmi: - Add entry for the Yours Y8W81 tablet - Add DMI match for the I.T.Works TW701 tablet thinkpad_acpi: - Add 2nd Fan Support for Thinkpad P50 topstar-laptop: - replace licence text with SPDX tag - update copyright and fix some comments - add Topstar U931/RVP7 WLAN LED workaround - add platform device - split ACPI events and input handling - use consistent naming scheme - revert "convert to module_acpi_driver()" wmi: - Fix misuse of vsprintf extension %pULL - Replace list_for_each() by list_for_each_entry() - Replace kmalloc + sprintf() with kasprintf() -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEhiZOUlnC9oKN3n3AmT3/83c5Sy0FAlrM6icACgkQmT3/83c5 Sy0qUA//Zg1uCmqTzvTxEsj7Z6RfwPV5IKE0pl86JufNXibuvxInVQI3qMU9D7lw Fl6n0k0HDoOEce5wo8fy7pic1WmmwDrapaV977elMfv4yGNQl/eIEoT6g9VBGMhE 9ORrdjBJtVYJR2rWLNH0DzeU2WoLUL0OwTQs0e3mj/mLazIARN6lC0qPDr9P4baE yXKkLGBmeuw2m0s3BfLVP5CDSanv0oB2IFsH5Qt1/y1qVT/VQnzcqFSSwz/IENm7 ZslNKR4Msi9/lDDt5HOsTADpgUI3m1t4fUReXx3MtcvuxZb6DdrHJWIAVU86NhKk /Yxm6/HU5/zpYgLXF+980GVjT6/KfPtRjJFoBItFtNeatj/oI9YStcaPFWwt2TFV hBHgS0OjPjuQNIizsjByitKerVEdsV7dJHY7wcmfq/3CpvB4Y8xrIJAa/Hj3HR34 SNbnl8vO1EfUu1vo1W4R8GfHxkIETKXT/hLpj54GSmSCzVY9lUQydyQwLTIC2Nsr L8XPsZyZfS6mq4ZeGfy9QDFbLZ9NephjnGFBiRceWM8xZKO0l8iDYMfd2sVfOP+v 4SzoWmLMVXS+ittObRo8i26B7ISlzVwdf3XCQA2ZgYeP/E/1ilo44Ifwf7ycOgeu Q8uk0mLAs0etfV8IqKwW3U5d/KzJEkBxYI4+HdL1IcQ2tAqe0J4= =SuHR -----END PGP SIGNATURE----- Merge tag 'platform-drivers-x86-v4.17-1' of git://git.infradead.org/linux-platform-drivers-x86 Pull x86 platform driver updates from Andy Shevchenko: - Dell SMBIOS driver fixed against memory leaks. - The fujitsu-laptop driver is cleaned up and now supports hotkeys for Lifebook U7x7 models.

New features:
- Tom Zanussi's extended histogram work
This adds the synthetic events to have histograms from multiple event data
Adds triggers "onmatch" and "onmax" to call the synthetic events
Several updates to the histogram code from this
- Allow way to nest ring buffer calls in the same context
- Allow absolute time stamps in ring buffer
- Rewrite of filter code parsing based on Al Viro's suggestions
- Setting of trace_clock to global if TSC is unstable (on boot)
- Better OOM handling when allocating large ring buffers
- Added initcall tracepoints (consolidated initcall_debug code with them)
And other various fixes and clean ups

libnvdimm for 4.17
* A rework of the filesytem-dax implementation provides for detection of
unmap operations (truncate / hole punch) colliding with in-progress
device-DMA. A fix for these collisions remains a work-in-progress
pending resolution of truncate latency and starvation regressions.
* The of_pmem driver expands the users of libnvdimm outside of x86 and
ACPI to describe an implementation of persistent memory on PowerPC with
Open Firmware / Device tree.
* Address Range Scrub (ARS) handling is completely rewritten to account for
the fact that ARS may run for 100s of seconds and there is no platform
defined way to cancel it. ARS will now no longer block namespace
initialization.
* The NVDIMM Namespace Label implementation is updated to handle label
areas as small as 1K, down from 128K.
* Miscellaneous cleanups and updates to unit test infrastructure.

Merge tag 'libnvdimm-for-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"This cycle was was not something I ever want to repeat as there were
several late changes that have only now just settled.
Half of the branch up to commit d2c997c0f145 ("fs, dax: use
page->mapping to warn...") have been in -next for several releases.
The of_pmem driver and the address range scrub rework were late
arrivals, and the dax work was scaled back at the last moment.
The of_pmem driver missed a previous merge window due to an oversight.
A sense of obligation to rectify that miss is why it is included for
4.17. It has acks from PowerPC folks. Stephen reported a build failure
that only occurs when merging it with your latest tree, for now I have
fixed that up by disabling modular builds of of_pmem. A test merge
with your tree has received a build success report from the 0day robot
over 156 configs.
An initial version of the ARS rework was submitted before the merge
window. It is self contained to libnvdimm, a net code reduction, and
passing all unit tests.
The filesystem-dax changes are based on the wait_var_event()
functionality from tip/sched/core. However, late review feedback
showed that those changes regressed truncate performance to a large
degree. The branch was rewound to drop the truncate behavior change
and now only includes preparation patches and cleanups (with full acks
and reviews). The finalization of this dax-dma-vs-trnucate work will
need to wait for 4.18.
Summary:
- A rework of the filesytem-dax implementation provides for detection
of unmap operations (truncate / hole punch) colliding with
in-progress device-DMA. A fix for these collisions remains a
work-in-progress pending resolution of truncate latency and
starvation regressions.
- The of_pmem driver expands the users of libnvdimm outside of x86

sound fixes for 4.17-rc1
The main purpose of this pull request is a fix for a regression in the recent PCM OSS emulation code that may lead to RCU stall.

Pull media fixes from Mauro Carvalho Chehab:
"A series of media updates/fixes for 4.17.
There are two important core fix patches in this series:
- A regression fix on Kernel 4.16 with causes it to not work with
some input devices that depend on media core
- A fix at compat32 bits with causes it to OOPS on overlay, and
affects the Kernels where the CVE-2017-13166 was backported
The remaining ones are other random fixes at the documentation and on
drivers.
The biggest part of this series is a set of 18 patches for the Intel
atomisp driver. Currently, it produces hundreds of warnings/errors on
sparse/smatch, causing me to sometimes ignore new warnings on other
drivers that are not so broken. This driver is on really poor state,
even for staging standards: it has several layers of abstraction on
it, and it supports two different hardware. Selecting between them
require to add a define (there isn't even a Kconfig option for such
purpose). Just on this smatch cleanup, I could easily get rid of 8
"do-nothing" files. So, I'm seriously considering its removal from
upstream, if I don't see any real work on addressing the problems
there along this year"

c6x: pass endianness info to sparse
c6x depends on the macro '_BIG_ENDIAN' being defined or not to correctly select or define endian-specific macros, structures or pieces of code. This macro is predefined by the compiler but sparse knows nothing about it and thus may pre-process files differently from what gcc would. Fix this by passing '-D_BIG_ENDIAN' when compiling a big-endian kernel, like GCC would have done.

selinux: fix missing dput() before selinuxfs unmount
Commit 0619f0f5e36f ("selinux: wrap selinuxfs state") triggers a BUG
when SELinux is runtime-disabled (i.e. systemd or equivalent disables
SELinux before initial policy load via /sys/fs/selinux/disable based on
/etc/selinux/config SELINUX=disabled).
This does not manifest if SELinux is disabled via kernel command line
argument or if SELinux is enabled (permissive or enforcing).
Before:
SELinux: Disabled at runtime.
BUG: Dentry 000000006d77e5c7{i=17,n=null} still in use (1) [unmount of selinuxfs selinuxfs]
After:
SELinux: Disabled at runtime.

Fix subtle macro variable shadowing in min_not_zero()
Commit 3c8ba0d61d04 ("kernel.h: Retain constant expression output for
max()/min()") rewrote our min/max macros to be very clever, but in the
meantime resurrected a variable name shadow issue that we had had
previously fixed in commit 589a9785ee3a ("min/max: remove sparse
warnings when they're nested").
That commit talks about the sparse warnings that this shadowing causes,
which we ignored as just a minor annoyance. But it turns out that the
sparse warning is the least of our problems. We actually have a real
bug due to the shadowing through the interaction with "min_not_zero()",
which ends up doing
min(__x, __y)
internally, and then the new declaration of "__x" and "__y" as new
variables in __cmp_once() results in a complete mess of an expression,
and "min_not_zero()" doesn't work at all.
For some odd reason, this only ever caused (reported) problems on s390,
even though it is a generic issue and most of the (obviously successful)
testing of the problematic commit had happened on other architectures.
Quoting Sebastian Ott:
"What happened is that the bio build by the partition detection code
was attempted to be split by the block layer because the block queue
had a max_sector setting of 0. blk_queue_max_hw_sectors uses
min_not_zero."
So re-introduce the use of __UNIQUE_ID() to make sure that the min/max
macros do not have these kinds of clashes.
[ That said, __UNIQUE_ID() itself has several issues that make it less
than wonderful.
In particular, the "uniqueness" has a fallback on the line number,
which means that it's not actually unique in more complex cases if you
don't build with gcc or clang (which have working unique counters that
aren't tied to line numbers).
That historical broken fallback also means that we have that pointless
"prefix" argument that doesn't actually make much sense _except_ for
the known-broken case. Oh well. ]

libnvdimm, of_pmem: workaround OF_NUMA=n build error
Stephen reports that an x86 allmodconfig build fails to build the of_pmem driver due to a missing definition of of_node_to_nid(). That helper is currently only exported in the OF_NUMA=y case. In other cases, ppc and sparc, it is a weak symbol, and outside of those platforms it is a static inline. Until an OF_NUMA=n configuration can reliably support usage of of_node_to_nid() in modules across architectures, mark this driver as 'bool' instead of 'tristate'.

- Improvements for the spectre defense:
* The spectre related code is consolidated to a single file
nospec-branch.c
* Automatic enable/disable for the spectre v2 defenses (expoline vs.
nobp)
* Syslog messages for specve v2 are added
* Enable CONFIG_GENERIC_CPU_VULNERABILITIES and define the attribute
functions for spectre v1 and v2
- Add helper macros for assembler alternatives and use them to shorten
the code in entry.S.
- Add support for persistent configuration data via the SCLP Store Data
interface. The H/W interface requires a page table that uses 4K pages
only, the code to setup such an address space is added as well.
- Enable virtio GPU emulation in QEMU. To do this the depends
statements for a few common Kconfig options are modified.
- Add support for format-3 channel path descriptors and add a binary
sysfs interface to export the associated utility strings.
- Add a sysfs attribute to control the IFCC handling in case of
constant channel errors.
- The vfio-ccw changes from Cornelia.
- Bug fixes and cleanups.

ALSA: pcm: Remove WARN_ON() at snd_pcm_hw_params() error
snd_pcm_hw_params() (more exactly snd_pcm_hw_params_choose()) contains a check of the return error from snd_pcm_hw_param_first() and _last() with snd_BUG_ON() -- i.e. it may trigger WARN_ON() depending on the kconfig. This was a valid check in the past, as these functions shouldn't return any error if the parameters have been already refined via snd_pcm_hw_refine() beforehand. However, the recent rewrite introduced a kmalloc() in snd_pcm_hw_refine() for removing VLA, and this brought a possibility to trigger an error. As a result, syzbot caught lots of superfluous kernel WARN_ON() and paniced via fault injection. As the WARN_ON() is no longer valid with the introduction of kmalloc(), let's drop snd_BUG_ON() check, in order to make the world peaceful place again.

vhost-net: set packet weight of tx polling to 2 * vq size
handle_tx will delay rx for tens or even hundreds of milliseconds when tx busy
polling udp packets with small length(e.g. 1byte udp payload), because setting
VHOST_NET_WEIGHT takes into account only sent-bytes but no single packet length.
Ping-Latencies shown below were tested between two Virtual Machines using
netperf (UDP_STREAM, len=1), and then another machine pinged the client:
vq size=256

Seems pretty consistent, a small dip at 2 VQ sizes.
Ring size is a hint from device about a burst size it can tolerate. Based on
benchmarks, set the weight to 2 * vq size.
To evaluate this change, another tests were done using netperf(RR, TX) between
two machines with Intel(R) Xeon(R) Gold 6133 CPU @ 2.50GHz, and vq size was
tweaked through qemu. Results shown below does not show obvious changes.

net: thunderx: rework mac addresses list to u64 array
It is too expensive to pass u64 values via linked list, instead
allocate array for them by overall number of mac addresses from netdev.
This eventually removes multiple kmalloc() calls, aviod memory
fragmentation and allow to put single null check on kmalloc
return value in order to prevent a potential null pointer dereference.

The main changes are: 1) Two sockmap fixes: i) fix a potential warning when a socket with pending cork data is closed by freeing the memory right when the socket is closed instead of seeing still outstanding memory at garbage collector time, ii) fix a NULL pointer deref in case of duplicates release calls, so make sure to only reset the sk_prot pointer when it's in a valid state to do so, both from John. 2) Fix a compilation warning in bpf_prog_attach_check_attach_type() by moving the function under CONFIG_CGROUP_BPF ifdef since only used there, from Anders. ==================== Signed-off-by: David S.
