git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
Pull ext4 updates from Ted Ts'o:
"This merge window saw the the following new featuers added to ext4:
- Direct I/O via iomap (required the iomap-for-next branch from
Darrick as a prereq).
- Support for using dioread-nolock where the block size < page size.
- Support for encryption for file systems where the block size < page
size.
- Rework of journal credits handling so a revoke-heavy workload will
not cause the journal to run out of space.
- Replace bit-spinlocks with spinlocks in jbd2
Also included were some bug fixes and cleanups, mostly to clean up
corner cases from fuzzed file systems and error path handling"

Pull iomap updates from Darrick Wong:
"In this release, we hoisted as much of XFS' writeback code into iomap
as was practicable, refactored the unshare file data function, added
the ability to perform buffered io copy on write, and tweaked various
parts of the directio implementation as needed to port ext4's directio
code (that will be a separate pull).
Summary:
- Make iomap_dio_rw callers explicitly tell us if they want us to
wait
- Port the xfs writeback code to iomap to complete the buffered io
library functions
- Refactor the unshare code to share common pieces
- Add support for performing copy on write with buffered writes
- Other minor fixes
- Fix unchecked return in iomap_bmap
- Fix a type casting bug in a ternary statement in
iomap_dio_bio_actor
- Improve tracepoints for easier diagnostic ability
- Fix pipe page leakage in directio reads"

git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull hmm updates from Jason Gunthorpe:
"This is another round of bug fixing and cleanup. This time the focus
is on the driver pattern to use mmu notifiers to monitor a VA range.
This code is lifted out of many drivers and hmm_mirror directly into
the mmu_notifier core and written using the best ideas from all the
driver implementations.
This removes many bugs from the drivers and has a very pleasing
diffstat. More drivers can still be converted, but that is for another
cycle.
- A shared branch with RDMA reworking the RDMA ODP implementation
- New mmu_interval_notifier API. This is focused on the use case of
monitoring a VA and simplifies the process for drivers
- A common seq-count locking scheme built into the
mmu_interval_notifier API usable by drivers that call
get_user_pages() or hmm_range_fault() with the VA range
- Conversion of mlx5 ODP, hfi1, radeon, nouveau, AMD GPU, and Xen
GntDev drivers to the new API. This deletes a lot of wonky driver
code.
- Two improvements for hmm_range_fault(), from testing done by Ralph"

Pull generic ioremap support from Christoph Hellwig:
"This adds the remaining bits for an entirely generic ioremap and
iounmap to lib/ioremap.c. To facilitate that, it cleans up the giant

For now just the three newest ports use the code, but there is more
than a handful others that can be converted without too much work.

git://people.freedesktop.org/~thomash/linux into drm-next
Graphics APIs like OpenGL 4.4 and Vulkan require the graphics driver
to provide coherent graphics memory, meaning that the GPU sees any
content written to the coherent memory on the next GPU operation that
touches that memory, and the CPU sees any content written by the GPU
to that memory immediately after any fence object trailing the GPU
operation is signaled.
Paravirtual drivers that otherwise require explicit synchronization
needs to do this by hooking up dirty tracking to pagefault handlers
and buffer object validation.
Provide mm helpers needed for this and that also allow for huge pmd-
and pud entries (patch 1-3), and the associated vmwgfx code (patch 4-7).
The code has been tested and exercised by a tailored version of mesa
where we disable all explicit synchronization and assume graphics memory
is coherent. The performance loss varies of course; a typical number is
around 5%.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing updates from Steven Rostedt:
"New tracing features:
- New PERMANENT flag to ftrace_ops when attaching a callback to a
function.
As /proc/sys/kernel/ftrace_enabled when set to zero will disable
all attached callbacks in ftrace, this has a detrimental impact on
live kernel tracing, as it disables all that it patched. If a
ftrace_ops is registered to ftrace with the PERMANENT flag set, it
will prevent ftrace_enabled from being disabled, and if
ftrace_enabled is already disabled, it will prevent a ftrace_ops
with PREMANENT flag set from being registered.
- New register_ftrace_direct().
As eBPF would like to register its own trampolines to be called by
the ftrace nop locations directly, without going through the ftrace
trampoline, this function has been added. This allows for eBPF
trampolines to live along side of ftrace, perf, kprobe and live
patching. It also utilizes the ftrace enabled_functions file that
keeps track of functions that have been modified in the kernel, to
allow for security auditing.
- Allow for kernel internal use of ftrace instances.
Subsystems in the kernel can now create and destroy their own
tracing instances which allows them to have their own tracing
buffer, and be able to record events without worrying about other
users from writing over their data.
- New seq_buf_hex_dump() that lets users use the hex_dump() in their
seq_buf usage.
- Notifications now added to tracing_max_latency to allow user space
to know when a new max latency is hit by one of the latency
tracers.
- Wider spread use of generic compare operations for use of bsearch
and friends.
- More synthetic event fields may be defined (32 up from 16)
- Use of xarray for architectures with sparse system calls, for the
system call trace events.
This along with small clean ups and fixes"

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH:
"Here is the "big" set of driver core patches for 5.5-rc1
There's a few minor cleanups and fixes in here, but the majority of
the patches in here fall into two buckets:
- debugfs api cleanups and fixes
- driver core device link support for boot dependancy issues
The debugfs api cleanups are working to slowly refactor the debugfs
apis so that it is even harder to use incorrectly. That work has been
happening for the past few kernel releases and will continue over
time, it's a long-term project/goal
The driver core device link support missed 5.4 by just a bit, so it's
been sitting and baking for many months now. It's from Saravana Kannan
to help resolve the problems that DT-based systems have at boot time
with dependancy graphs and kernel modules. Turns out that no one has
actually tried to build a generic arm64 kernel with loads of modules
and have it "just work" for a variety of platforms (like a distro
kernel). The big problem turned out to be a lack of dependency
information between different areas of DT entries, and the work here
resolves that problem and now allows devices to boot properly, and
quicker than a monolith kernel.
All of these patches have been in linux-next for a long time with no
reported issues"

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for v5.5.
It is pretty much business as usual, the most interesting thing I
think is the pin controller for a new Intel chip called Lightning
Mountain, which is according to news reports some kind of embedded
network processor and what is surprising about it is that Intel have
decided to use device tree to describe the system rather than ACPI
that they have traditionally favored.
Core changes:
- Avoid taking direct references to device tree-supplied device
names: these may changed at runtime under certain circumstances to
kstrdup them.
GPIO related:
- Work is ongoing to move to passing the irqchip along as a templated
struct gpio_irq_chip when adding a standard gpiolib-based irqchip
to a GPIO controller, a few patches in this cycle switches a few
pin control drivers over to using this method.
New hardware support:
- Intel Lightning Mountain SoC pin controller and GPIO support, a
first Intel platform to use device tree rather than ACPI to
configure the system. News reports says that this SoC is a network
processor.
- Qualcomm MSM8976 and MSM8956
- Qualcomm PMIC GPIO now also supports PM6150 and PM6150L
- Qualcomm SPMI MPP and SPMI GPIO for PM8950 and PMI8950
- Rockchip RK3308
- Renesas R8A77961
- Allwinner Meson-A1
Driver improvements:
- get_multiple and set_multiple support for the AT91-PIO4 driver.
- Convert Qualcomm SSBI GPIO to use the hierarchical IRQ helpers in
the GPIOlib irqchip"

Pull locking updates from Ingo Molnar:
"The main changes in this cycle were:
- A comprehensive rewrite of the robust/PI futex code's exit handling
to fix various exit races. (Thomas Gleixner et al)
- Rework the generic REFCOUNT_FULL implementation using
atomic_fetch_* operations so that the performance impact of the
cmpxchg() loops is mitigated for common refcount operations.
With these performance improvements the generic implementation of
refcount_t should be good enough for everybody - and this got
confirmed by performance testing, so remove ARCH_HAS_REFCOUNT and
REFCOUNT_FULL entirely, leaving the generic implementation enabled
unconditionally. (Will Deacon)

Pull scheduler updates from Ingo Molnar:
"The biggest changes in this cycle were:
- Make kcpustat vtime aware (Frederic Weisbecker)
- Rework the CFS load_balance() logic (Vincent Guittot)
- Misc cleanups, smaller enhancements, fixes.
The load-balancing rework is the most intrusive change: it replaces
the old heuristics that have become less meaningful after the
introduction of the PELT metrics, with a grounds-up load-balancing
algorithm.
As such it's not really an iterative series, but replaces the old
load-balancing logic with the new one. We hope there are no
performance regressions left - but statistically it's highly probable
that there *is* going to be some workload that is hurting from these
chnages. If so then we'd prefer to have a look at that workload and
fix its scheduling, instead of reverting the changes"

Note that the sysctl write accessor functions guarantee that:
net->ipv4.sysctl_ip_prot_sock <= net->ipv4.ip_local_ports.range[0]
invariant is maintained, and as such the max() in selinux hooks is actually spurious.
ie. even though
if (snum < max(inet_prot_sock(sock_net(sk)), low) || snum > high) {
per logic is the same as
if ((snum < inet_prot_sock(sock_net(sk)) && snum < low) || snum > high) {
it is actually functionally equivalent to:
if (snum < low || snum > high) {
which is equivalent to:
if (snum < inet_prot_sock(sock_net(sk)) || snum < low || snum > high) {
even though the first clause is spurious.
But we want to hold on to it in case we ever want to change what what
inet_port_requires_bind_service() means (for example by changing
it from a, by default, [0..1024) range to some sort of set).
Test: builds, git 'grep inet_prot_sock' finds no other references

This reverts commit 0be0ee71816b2b6725e2b4f32ad6726c9d729777.
I was hoping it would be benign to switch over entirely to FMODE_STREAM,
and we'd have just a couple of small fixups we'd need, but it looks like
we're not quite there yet.
While it worked fine on both my desktop and laptop, they are fairly
similar in other respects, and run mostly the same loads. Kenneth
Crudup reports that it seems to break both his vmware installation and
the KDE upower service. In both cases apparently leading to timeouts
due to waitinmg for the f_pos lock.
There are a number of character devices in particular that definitely
want stream-like behavior, but that currently don't get marked as
streams, and as a result get the exclusion between concurrent
read()/write() on the same file descriptor. Which doesn't work well for
them.
The most obvious example if this is /dev/console and /dev/tty, which use
console_fops and tty_fops respectively (and ptmx_fops for the pty master
side). It may be that it's just this that causes problems, but we
clearly weren't ready yet.
Because there's a number of other likely common cases that don't have
llseek implementations and would seem to act as stream devices:
/dev/fuse (fuse_dev_operations)
/dev/mcelog (mce_chrdev_ops)
/dev/mei0 (mei_fops)
/dev/net/tun (tun_fops)
/dev/nvme0 (nvme_dev_fops)
/dev/tpm0 (tpm_fops)
/proc/self/ns/mnt (ns_file_operations)
/dev/snd/pcm* (snd_pcm_f_ops[])
and while some of these could be trivially automatically detected by the
vfs layer when the character device is opened by just noticing that they
have no read or write operations either, it often isn't that obvious.
Some character devices most definitely do use the file position, even if
they don't allow seeking: the firmware update code, for example, uses
simple_read_from_buffer() that does use f_pos, but doesn't allow seeking
back and forth.
We'll revisit this when there's a better way to detect the problem and
fix it (possibly with a coccinelle script to do more of the FMODE_STREAM
annotations).

- Switch the x86 linker fill byte from x90 (NOP) to 0xcc (INT3), to

sliding execution. (Kees Cook)

SYM_FUNC_START(name)
