Merge tag 'xfs-4.14-merge-7' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull XFS updates from Darrick Wong:
"Here are the changes for xfs for 4.14. Most of these are cleanups and
fixes for bad behavior, as we're mostly focusing on improving
reliablity this cycle (read: there's potentially a lot of stuff on the
horizon for 4.15 so better to spend a few weeks killing other bugs
now).
Summary:
- Write unmount record for a ro mount to avoid unnecessary log replay
- Clean up orphaned inodes when mounting fs readonly
- Resubmit inode log items when buffer writeback fails to avoid
umount hang
- Fix log recovery corruption problems when log headers wrap around
the end
- Avoid infinite loop searching for free inodes when inode counters
are wrong
- Evict inodes involved with log redo so that we don't leak them
later
- Fix a potential race between reclaim and inode cluster freeing
- Refactor the inode joining code w.r.t. transaction rolling &
deferred ops
- Fix a bug where the log doesn't properly deal with dirty buffers
that are about to become ordered buffers
- Fix the extent swap code to deal with making dirty buffers ordered
properly
- Consolidate page fault handlers
- Refactor the incore extent manipulation functions to use the iext
abstractions instead of directly modifying with extent data
- Disable crashy chattr +/-x until we fix it
- Don't allow us to set S_DAX for v2 inodes
- Various cleanups
- Clarify some documentation
- Fix a problem where fsync and a log commit race to send the disk a
flush command, resulting in a small window where power fail data
loss could occur
- Simplify some rmap operations in the fcollapse code
- Fix some use-after-free problems in async writeback"

Merge tag 'gfs2-4.14.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2
Pull GFS2 updates from Bob Peterson:
"We've got a whopping 29 GFS2 patches for this merge window, mainly
because we held some back from the previous merge window until we
could get them perfected and well tested. We have a couple patch sets,
including my patch set for protecting glock gl_object and Andreas
Gruenbacher's patch set to fix the long-standing shrink- slab hang,
plus a bunch of assorted bugs and cleanups.
Summary:
- I fixed a bug whereby an IO error would lead to a double-brelse.
- Andreas Gruenbacher made a minor cleanup to call his relatively new
function, gfs2_holder_initialized, rather than doing it manually.
This was just missed by a previous patch set.
- Jan Kara fixed a bug whereby the SGID was being cleared when
inheriting ACLs.
- Andreas found a bug and fixed it in his previous patch, "Get rid of
flush_delayed_work in gfs2_evict_inode". A call to
flush_delayed_work was deleted from *gfs2_inode_lookup and added to
gfs2_create_inode.
- Wang Xibo found and fixed a list_add call in inode_go_lock that
specified the parameters in the wrong order.
- Coly Li submitted a patch to add the REQ_PRIO to some of GFS2's
metadata reads that were accidentally missing them.
- I submitted a 4-patch set to protect the glock gl_object field.
GFS2 was setting and checking gl_object with no locking mechanism,
so the value was occasionally stomped on, which caused file system
corruption.
- I submitted a small cleanup to function gfs2_clear_rgrpd. It was
needlessly adding rgrp glocks to the lru list, then pulling them
back off immediately. The rgrp glocks don't use the lru list
anyway, so doing so was just a waste of time.
- I submitted a patch that checks the GLOF_LRU flag on a glock before
trying to remove it from the lru_list. This avoids a lot of
unnecessary spin_lock contention.
- I submitted a patch to delete GFS2's debugfs files only after we
evict all the glocks. Before this patch, GFS2 would delete the
debugfs files, and if unmount hung waiting for a glock, there was
no way to debug the problem. Now, if a hang occurs during umount,
we can examine the debugfs files to figure out why it's hung.
- Andreas Gruenbacher submitted a patch to fix some trivial typos.
- Andreas also submitted a five-part patch set to fix the
longstanding hang involving the slab shrinker: dlm requires memory,
calls the inode shrinker, which calls gfs2's evict, which calls
back into DLM before it can evict an inode.
- Abhi Das submitted a patch to forcibly flush the active items list
to relieve memory pressure. This fixes a long-standing bug whereby
GFS2 was getting hung permanently in balance_dirty_pages.
- Thomas Tai submitted a patch to fix a slab corruption problem due
to a residual pointer left in the lock_dlm lockstruct.
- I submitted a patch to withdraw the file system if IO errors are
encountered while writing to the journals or statfs system file
which were previously not being sent back up. Before, some IO
errors were sometimes not be detected for several hours, and at
recovery time, the journal errors made journal replay impossible.
- Andreas has a patch to fix an annoying format-truncation compiler
warning so GFS2 compiles cleanly.
- I have a patch that fixes a handful of sparse compiler warnings.
- Andreas fixed up an useless gl_object warning caused by an earlier
patch.
- Arvind Yadav added a patch to properly constify our rhashtable
params declare.
- I added a patch to fix a regression caused by the non-recursive
delete and truncate patch that caused file system blocks to not be
properly freed.
- Ernesto A. Fernández added a patch to fix a place where GFS2 would
send back the wrong return code setting extended attributes.
- Ernesto also added a patch to fix a case in which GFS2 was
improperly setting an inode's i_mode, potentially granting access
to the wrong users"

Pull power management updates from Rafael Wysocki:
"This time (again) cpufreq gets the majority of changes which mostly
are driver updates (including a major consolidation of intel_pstate),
some schedutil governor modifications and core cleanups.
There also are some changes in the system suspend area, mostly related
to diagnostics and debug messages plus some renames of things related
to suspend-to-idle. One major change here is that suspend-to-idle is
now going to be preferred over S3 on systems where the ACPI tables
indicate to do so and provide requsite support (the Low Power Idle S0
_DSM in particular). The system sleep documentation and the tools
related to it are updated too.
The rest is a few cpuidle changes (nothing major), devfreq updates,
generic power domains (genpd) framework updates and a few assorted
modifications elsewhere.
Specifics:
- Drop the P-state selection algorithm based on a PID controller from
intel_pstate and make it use the same P-state selection method
(based on the CPU load) for all types of systems in the active mode
(Rafael Wysocki, Srinivas Pandruvada).
- Rework the cpufreq core and governors to make it possible to take
cross-CPU utilization updates into account and modify the schedutil
governor to actually do so (Viresh Kumar).
- Clean up the handling of transition latency information in the
cpufreq core and untangle it from the information on which drivers
cannot do dynamic frequency switching (Viresh Kumar).
- Add support for new SoCs (MT2701/MT7623 and MT7622) to the mediatek
cpufreq driver and update its DT bindings (Sean Wang).
- Modify the cpufreq dt-platdev driver to autimatically create
cpufreq devices for the new (v2) Operating Performance Points (OPP)
DT bindings and update its whitelist of supported systems (Viresh
Kumar, Shubhrajyoti Datta, Marc Gonzalez, Khiem Nguyen, Finley
Xiao).
- Add support for Ux500 to the cpufreq-dt driver and drop the
obsolete dbx500 cpufreq driver (Linus Walleij, Arnd Bergmann).
- Add new SoC (R8A7795) support to the cpufreq rcar driver (Khiem
Nguyen).
- Fix and clean up assorted issues in the cpufreq drivers and core
(Arvind Yadav, Christophe Jaillet, Colin Ian King, Gustavo Silva,
Julia Lawall, Leonard Crestez, Rob Herring, Sudeep Holla).
- Update the IO-wait boost handling in the schedutil governor to make
it less aggressive (Joel Fernandes).
- Rework system suspend diagnostics to make it print fewer messages
to the kernel log by default, add a sysfs knob to allow more
suspend-related messages to be printed and add Low Power S0 Idle
constraints checks to the ACPI suspend-to-idle code (Rafael
Wysocki, Srinivas Pandruvada).
- Prefer suspend-to-idle over S3 on ACPI-based systems with the
ACPI_FADT_LOW_POWER_S0 flag set and the Low Power Idle S0 _DSM
interface present in the ACPI tables (Rafael Wysocki).
- Update documentation related to system sleep and rename a number of
items in the code to make it cleare that they are related to
suspend-to-idle (Rafael Wysocki).
- Export a variable allowing device drivers to check the target
system sleep state from the core system suspend code (Florian
Fainelli).
- Clean up the cpuidle subsystem to handle the polling state on x86
in a more straightforward way and to use %pOF instead of full_name
(Rafael Wysocki, Rob Herring).
- Update the devfreq framework to fix and clean up a few minor issues
(Chanwoo Choi, Rob Herring).
- Extend diagnostics in the generic power domains (genpd) framework
and clean it up slightly (Thara Gopinath, Rob Herring).
- Fix and clean up a couple of issues in the operating performance
points (OPP) framework (Viresh Kumar, Waldemar Rymarkiewicz).
- Add support for RV1108 to the rockchip-io Adaptive Voltage Scaling
(AVS) driver (David Wu).
- Fix the usage of notifiers in CPU power management on some
platforms (Alex Shi).
- Update the pm-graph system suspend/hibernation and boot profiling
utility (Todd Brandt).
- Make it possible to run the cpupower utility without CPU0 (Prarit
Bhargava)"

Merge tag 'gpio-v4.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the bulk of the GPIO changes for the v4.14 cycle.
Not so much changes this time, phew. David Daney and Bartosz
Golaszewski did all the really interesting work in infrastructure
improvement across GPIO and IRQ core, hats off for them and to tglx
and Marc Z for general help with these patch sets.
Core changes:
- Allow the GPIO irqchip to allocate IRQs dynamically. This is an
important change on systems where only a restricted number of IRQs,
lesser than the number of GPIO lines, can be utilized. Now we can
allocate these on a first-come-first-served basis instead of
hogging up valuable IRQ lines.
- Serious fix-up of the kerneldoc documentation and inclusion into
the kerneldoc builds.
- Pulled in the IRQ simulator from the IRQ core tree and use this in
the GPIO mockup driver for exhaustive testing of interrupt
abilities.
New drivers:
- New driver for ThunderX and OCTEON-TX. This is especially
interesting as it picks up improvements from the IRQ core that
allow us to handle fasteoi ACKs upwards in a hierarchy when there
are IRQ flag latches on several levels in a hierarchy. Very
interesting work here.
- New subdriver for Renesas R-Car r8a7745 (RZ/G1E).
Misc:
- Several fixes and improvements for Xilinx Zynq GPIO.
- Support an enablement GPIO for the 74x164 GPIO.
- Switch a bunch of chips to use devres to allocate irq descriptors.
- A bunch of constification fixes"

layer together with API improvements so that the architecture code
can detect between contiguous and non-contiguous huge PTEs
- Initial support for persistent memory on ARM: DC CVAP instruction
exposed to user space (HWCAP) and the in-kernel pmem API implemented
- raid6 improvements for arm64: faster algorithm for the delta syndrome
and implementation of the recovery routines using Neon
- FP/SIMD refactoring and removal of support for Neon in interrupt
context. This is in preparation for full SVE support

Pull x86 mm changes from Ingo Molnar:
"PCID support, 5-level paging support, Secure Memory Encryption support
The main changes in this cycle are support for three new, complex
hardware features of x86 CPUs:
- Add 5-level paging support, which is a new hardware feature on
upcoming Intel CPUs allowing up to 128 PB of virtual address space
and 4 PB of physical RAM space - a 512-fold increase over the old
limits. (Supercomputers of the future forecasting hurricanes on an
ever warming planet can certainly make good use of more RAM.)
Many of the necessary changes went upstream in previous cycles,
v4.14 is the first kernel that can enable 5-level paging.
This feature is activated via CONFIG_X86_5LEVEL=y - disabled by
default.
(By Kirill A. Shutemov)
- Add 'encrypted memory' support, which is a new hardware feature on
upcoming AMD CPUs ('Secure Memory Encryption', SME) allowing system
RAM to be encrypted and decrypted (mostly) transparently by the
CPU, with a little help from the kernel to transition to/from
encrypted RAM. Such RAM should be more secure against various
attacks like RAM access via the memory bus and should make the
radio signature of memory bus traffic harder to intercept (and
decrypt) as well.
This feature is activated via CONFIG_AMD_MEM_ENCRYPT=y - disabled
by default.
(By Tom Lendacky)
- Enable PCID optimized TLB flushing on newer Intel CPUs: PCID is a
hardware feature that attaches an address space tag to TLB entries
and thus allows to skip TLB flushing in many cases, even if we
switch mm's.
(By Andy Lutomirski)
All three of these features were in the works for a long time, and
it's coincidence of the three independent development paths that they
are all enabled in v4.14 at once"

Pull x86 asm updates from Ingo Molnar: - Introduce the ORC unwinder, which can be enabled via CONFIG_ORC_UNWINDER=y. The ORC unwinder is a lightweight, Linux kernel specific debuginfo implementation, which aims to be DWARF done right for unwinding. Objtool is used to generate the ORC unwinder tables during build, so the data format is flexible and kernel internal: there's no dependency on debuginfo created by an external toolchain. The ORC unwinder is almost two orders of magnitude faster than the (out of tree) DWARF unwinder - which is important for perf call graph profiling. It is also significantly simpler and is coded defensively: there has not been a single ORC related kernel crash so far, even with early versions. (knock on wood!) But the main advantage is that enabling the ORC unwinder allows CONFIG_FRAME_POINTERS to be turned off - which speeds up the kernel measurably: With frame pointers disabled, GCC does not have to add frame pointer instrumentation code to every function in the kernel. The kernel's .text size decreases by about 3.2%, resulting in better cache utilization and fewer instructions executed, resulting in a broad kernel-wide speedup. Average speedup of system calls should be roughly in the 1-3% range - measurements by Mel Gorman [1] have shown a speedup of 5-10% for some function execution intense workloads. The main cost of the unwinder is that the unwinder data has to be stored in RAM: the memory cost is 2-4MB of RAM, depending on kernel config - which is a modest cost on modern x86 systems. Given how young the ORC unwinder code is it's not enabled by default - but given the performance advantages the plan is to eventually make it the default unwinder on x86. See Documentation/x86/orc-unwinder.txt for more details. - Remove lguest support: its intended role was that of a temporary proof of concept for virtualization, plus its removal will enable the reduction (removal) of the paravirt API as well, so Rusty agreed to its removal.

Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Ingo Molnar:
"Kernel side changes:
- Add branch type profiling/tracing support. (Jin Yao)
- Add the PERF_SAMPLE_PHYS_ADDR ABI to allow the tracing/profiling of
physical memory addresses, where the PMU supports it. (Kan Liang)
- Export some PMU capability details in the new
/sys/bus/event_source/devices/cpu/caps/ sysfs directory. (Andi
Kleen)
- Aux data fixes and updates (Will Deacon)
- kprobes fixes and updates (Masami Hiramatsu)
- AMD uncore PMU driver fixes and updates (Janakarajan Natarajan)
On the tooling side, here's a (limited!) list of highlights - there
were many other changes that I could not list, see the shortlog and
git history for details:
UI improvements:
- Implement a visual marker for fused x86 instructions in the
annotate TUI browser, available now in 'perf report', more work
needed to have it available as well in 'perf top' (Jin Yao)
Further explanation from one of Jin's patches:
│ ┌──cmpl $0x0,argp_program_version_hook
81.93 │ ├──je 20
│ │ lock cmpxchg %esi,0x38a9a4(%rip)
│ │↓ jne 29
│ │↓ jmp 43
11.47 │20:└─→cmpxch %esi,0x38a999(%rip)
That means the cmpl+je is a fused instruction pair and they should
be considered together.
- Record the branch type and then show statistics and info about in
callchain entries (Jin Yao)
Example from one of Jin's patches:
# perf record -g -j any,save_type
# perf report --branch-history --stdio --no-children

__random random.c:295 (RET CROSS_2M cycles:9)
namespaces support:
- Add initial support for namespaces, using setns to access files in
namespaces, grabbing their build-ids, etc. (Krister Johansen)
perf trace enhancements:
- Beautify pkey_{alloc,free,mprotect} arguments in 'perf trace'
(Arnaldo Carvalho de Melo)
- Add initial 'clone' syscall args beautifier in 'perf trace'
(Arnaldo Carvalho de Melo)
- Ignore 'fd' and 'offset' args for MAP_ANONYMOUS in 'perf trace'
(Arnaldo Carvalho de Melo)
- Beautifiers for the 'cmd' arg of several ioctl types, including:
sound, DRM, KVM, vhost virtio and perf_events. (Arnaldo Carvalho de
Melo)
- Add PERF_SAMPLE_CALLCHAIN and PERF_RECORD_MMAP[2] to 'perf data'
CTF conversion, allowing CTF trace visualization tools to show
callchains and to resolve symbols (Geneviève Bastien)
- Beautify the fcntl syscall, which is an interesting one in the
sense that infrastructure had to be put in place to change the
formatters of some arguments according to the value in a previous
one, i.e. cmd dictates how arg and the syscall return will be
formatted. (Arnaldo Carvalho de Melo
perf stat enhancements:
- Use group read for event groups in 'perf stat', reducing overhead
when groups are defined in the event specification, i.e. when using
{} to enclose a list of events, asking them to be read at the same
time, e.g.: "perf stat -e '{cycles,instructions}'" (Jiri Olsa)
pipe mode improvements:
- Process tracing data in 'perf annotate' pipe mode (David
Carrillo-Cisneros)
- Add header record types to pipe-mode, now this command:
$ perf record -o - -e cycles sleep 1 | perf report --stdio --header
Will show the same as in non-pipe mode, i.e. involving a perf.data
file (David Carrillo-Cisneros)
Vendor specific hardware event support updates/enhancements:
- Update POWER9 vendor events tables (Sukadev Bhattiprolu)
- Add POWER9 PMU events Sukadev (Bhattiprolu)
- Support additional POWER8+ PVR in PMU mapfile (Shriya)
- Add Skylake server uncore JSON vendor events (Andi Kleen)
- Support exporting Intel PT data to sqlite3 with python perf
scripts, this is in addition to the postgresql support that was
already there (Adrian Hunter)"

Merge tag 'for-linus-ioctl' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull rdma updates from Doug Ledford:
"This is a big pull request.
Of note is that I'm sending you the new ioctl API for the rdma
subsystem. We put it up on linux-api@, but didn't get much response.
The API is complex, but it solves two different problems in one go:
1) The bi-directional nature of the RDMA file write calls, which
created the security hole we had to handle (and for which the fix
is now causing problems for systems in production, we were a bit
over zealous in the fix and the ability to open a device, then
fork, then create new queue pairs on the device and use them is
broken).
2) The bloat caused by different vendors implementing extensions to
the base verbs API. Each vendor's hardware is slightly different,
and the hardware might be suitable for one extension but not
another.
By the time we add generic extensions for all the different ways
that the different hardware can offload things, the API becomes
bloated. Things like our completion structs have started to exceed
a cache line in size because of all the elements needed to support
this. That in turn shows up heavily in the performance graphs with
a noticable drop in performance on 100Gigabit links as our
completion structs go from occupying one cache line to 1+.
This API makes things like the completion structs modular in a
very similar way to netlink so that your structs can only include
the items needed for the offloads/features you are actually using
on a given queue pair. In that way we support everything, but only
use what we need, and our structs stay smaller.
The ioctl API is better explained by the posting on linux-api@ than I
can explain it here, so I'll just leave it at that.
The rest of the pull request is typical stuff.

Avoid page waitqueue race leaving possible page locker waiting
The "lock_page_killable()" function waits for exclusive access to the
page lock bit using the WQ_FLAG_EXCLUSIVE bit in the waitqueue entry
set.
That means that if it gets woken up, other waiters may have been
skipped.
That, in turn, means that if it sees the page being unlocked, it *must*
take that lock and return success, even if a lethal signal is also
pending.
So instead of checking for lethal signals first, we need to check for
them after we've checked the actual bit that we were waiting for. Even
if that might then delay the killing of the process.
This matches the order of the old "wait_on_bit_lock()" infrastructure
that the page locking used to use (and is still used in a few other
areas).
Note that if we still return an error after having unsuccessfully tried
to acquire the page lock, that is ok: that means that some other thread
was able to get ahead of us and lock the page, and when that other
thread then unlocks the page, the wakeup event will be repeated. So any
other pending waiters will now get properly woken up.
Fixes:

Minor page waitqueue cleanups
Tim Chen and Kan Liang have been battling a customer load that shows
extremely long page wakeup lists. The cause seems to be constant NUMA
migration of a hot page that is shared across a lot of threads, but the
actual root cause for the exact behavior has not been found.
Tim has a patch that batches the wait list traversal at wakeup time, so
that we at least don't get long uninterruptible cases where we traverse
and wake up thousands of processes and get nasty latency spikes. That
is likely 4.14 material, but we're still discussing the page waitqueue
specific parts of it.
In the meantime, I've tried to look at making the page wait queues less
expensive, and failing miserably. If you have thousands of threads
waiting for the same page, it will be painful. We'll need to try to
figure out the NUMA balancing issue some day, in addition to avoiding
the excessive spinlock hold times.
That said, having tried to rewrite the page wait queues, I can at least
fix up some of the braindamage in the current situation. In particular:
(a) we don't want to continue walking the page wait list if the bit
we're waiting for already got set again (which seems to be one of
the patterns of the bad load). That makes no progress and just
causes pointless cache pollution chasing the pointers.
(b) we don't want to put the non-locking waiters always on the front of
the queue, and the locking waiters always on the back. Not only is
that unfair, it means that we wake up thousands of reading threads
that will just end up being blocked by the writer later anyway.
Also add a comment about the layout of 'struct wait_page_key' - there is
an external user of it in the cachefiles code that means that it has to
match the layout of 'struct wait_bit_key' in the two first members. It
so happens to match, because 'struct page *' and 'unsigned long *' end
up having the same values simply because the page flags are the first
member in struct page.

Clarify (and fix) MAX_LFS_FILESIZE macros
We have a MAX_LFS_FILESIZE macro that is meant to be filled in by filesystems (and other IO targets) that know they are 64-bit clean and don't have any 32-bit limits in their IO path. It turns out that our 32-bit value for that limit was bogus. On 32-bit, the VM layer is limited by the page cache to only 32-bit index values, but our logic for that was confusing and actually wrong. We used to define that value to (((loff_t)PAGE_SIZE << (BITS_PER_LONG-1))-1) which is actually odd in several ways: it limits the index to 31 bits, and then it limits files so that they can't have data in that last byte of a page that has the highest 31-bit index (ie page index 0x7fffffff). Neither of those limitations make sense. The index is actually the full 32 bit unsigned value, and we can use that whole full page. So the maximum size of the file would logically be "PAGE_SIZE << BITS_PER_LONG". However, we do wan tto avoid the maximum index, because we have code that iterates over the page indexes, and we don't want that code to overflow. So the maximum size of a file on a 32-bit host should actually be one page less than the full 32-bit index. So the actual limit is ULONG_MAX << PAGE_SHIFT. That means that we will not actually be using the page of that last index (ULONG_MAX), but we can grow a file up to that limit. The wrong value of MAX_LFS_FILESIZE actually caused problems for Doug Nazar, who was still using a 32-bit host, but with a 9.7TB 2 x RAID5 volume. It turns out that our old MAX_LFS_FILESIZE was 8TiB (well, one byte less), but the actual true VM limit is one page less than 16TiB. This was invisible until commit |
