io_uring: don't read user-shared sqe flags twice
Don't re-read userspace-shared sqe->flags, it can be exploited. sqe->flags are copied into req->flags in io_submit_sqe(), check them there instead. Signed-off-by: Pavel Begunkov <asml.silence@gmail.com> Signed-off-by: Jens Axboe <axboe@kernel.dk> |

io_uring: remove req init from io_get_req()
io_get_req() do two different things: io_kiocb allocation and initialisation. Move init part out of it and rename into io_alloc_req(). It's simpler this way and also have better data locality. Signed-off-by: Pavel Begunkov <asml.silence@gmail.com> Signed-off-by: Jens Axboe <axboe@kernel.dk> |

io_uring: alloc req only after getting sqe
As io_get_sqe() split into 2 stage get/consume, get an sqe before allocating io_kiocb, so no free_req*() for a failure case is needed, and inline back __io_req_do_free(), which has only 1 user. Signed-off-by: Pavel Begunkov <asml.silence@gmail.com> Signed-off-by: Jens Axboe <axboe@kernel.dk> |

io_uring: do not always copy iovec in io_req_map_rw()
In io_read_prep() or io_write_prep(), io_req_map_rw() takes struct io_async_rw's fast_iov as argument to call io_import_iovec(), and if io_import_iovec() uses struct io_async_rw's fast_iov as valid iovec array, later indeed io_req_map_rw() does not need to do the memcpy operation, because they are same pointers.

io_uring: ensure openat sets O_LARGEFILE if needed
OPENAT2 correctly sets O_LARGEFILE if it has to, but that escaped the
OPENAT opcode. Dmitry reports that his test case that compares openat()

*** sync openat
openat succeeded

*** io_uring openat
openat succeeded
sync write at offset 0

sync write at offset 4294967296
write failed: File too large
*** io_uring openat
openat succeeded
io_uring write at offset 0
write succeeded
io_uring write at offset 4294967296
write failed: File too large
Ensure we set O_LARGEFILE, if force_o_largefile() is true.

io_uring: remove redundant variable pointer nxt and io_wq_assign_next call
An earlier commit "io_uring: remove @nxt from handlers" removed the
setting of pointer nxt and now it is always null, hence the non-null
check and call to io_wq_assign_next is redundant and can be removed.

io_uring: fix ctx refcounting in io_submit_sqes()
If io_get_req() fails, it drops a ref. Then, awhile keeping @submitted
unmodified, io_submit_sqes() breaks the loop and puts @nr - @submitted
refs. For each submitted req a ref is dropped in io_put_req() and
friends. So, for @nr taken refs there will be
(@nr - @submitted + @submitted + 1) dropped.
Remove ctx refcounting from io_get_req(), that at the same time makes
it clearer.

We already checked this limit when the file was opened, and we keep it open in the file table. Hence when we added unit_inflight to the count we want to register, we're doubly accounting these files.

io_uring: refactor file register/unregister/update handling
While diving into io_uring fileset register/unregister/update codes, we found one bug in the fileset update handling. io_uring fileset update use a percpu_ref variable to check whether we can put the previously registered file, only when the refcnt of the perfcpu_ref variable reaches zero, can we safely put these files. But this doesn't work so well. If applications always issue requests continually, this perfcpu_ref will never have an chance to reach zero, and it'll always be in atomic mode, also will defeat the gains introduced by fileset register/unresiger/update feature, which are used to reduce the atomic operation overhead of fput/fget. To fix this issue, while applications do IORING_REGISTER_FILES or IORING_REGISTER_FILES_UPDATE operations, we allocate a new percpu_ref and kill the old percpu_ref, new requests will use the new percpu_ref. Once all previous old requests complete, old percpu_refs will be dropped and registered files will be put safely.

x86 timer updates:
- A series of commits to make the MSR derived CPU and TSC frequency more
accurate.
It turned out that the frequency tables which have been taken from the
SDM are inaccurate because the SDM provides truncated and rounded
values, e.g. 83.3Mhz (83.3333...) or 116.7Mhz (116.6666...).
This causes time drift in the range of ~1 second per hour
(20-30 seconds per day). On some of these SoCs it's not possible to
recalibrate the TSC because there is no reference (PIT, HPET) available.
With some reverse engineering it was established that the possible
frequencies are derived from the base clock with fixed multiplier /
divider pairs.
For the CPU models which have a known crystal frequency the kernel now
uses multiplier / divider pairs which bring the frequencies closer to
reality and fix the observed time drift issues.

Support for "split lock" detection:
- Atomic operations (lock prefixed instructions) which span two cache
lines have to acquire the global bus lock. This is at least 1k cycles
slower than an atomic operation within a cache line and disrupts
performance on other cores. Aside of performance disruption this is
a unpriviledged form of DoS.
Some newer CPUs have the capability to raise an #AC trap when such an
operation is attempted. The detection is by default enabled in warning
mode which will warn once when a user space application is caught. A
command line option allows to disable the detection or to select fatal
mode which will terminate offending applications with SIGBUS.

timekeeping and timer updates:
Core:
- Consolidation of the vDSO build infrastructure to address the
difficulties of cross-builds for ARM64 compat vDSO libraries by
restricting the exposure of header content to the vDSO build.
This is achieved by splitting out header content into separate
headers. which contain only the minimaly required information which is
necessary to build the vDSO. These new headers are included from the
kernel headers and the vDSO specific files.
- Enhancements to the generic vDSO library allowing more fine grained
control over the compiled in code, further reducing architecture
specific storage and preparing for adopting the generic library by PPC.
- Cleanup and consolidation of the exit related code in posix CPU timers.
- Small cleanups and enhancements here and there
Drivers:
- The obligatory new drivers: Ingenic JZ47xx and X1000 TCU support
- Correct the clock rate of PIT64b global clock
- setup_irq() cleanup
- Preparation for PWM and suspend support for the TI DM timer
- Expand the fttmr010 driver to support ast2600 systems
- The usual small fixes, enhancements and cleanups all over the place

Pull timekeeping and timer updates from Thomas Gleixner:
"Core:
- Consolidation of the vDSO build infrastructure to address the
difficulties of cross-builds for ARM64 compat vDSO libraries by
restricting the exposure of header content to the vDSO build.
This is achieved by splitting out header content into separate
headers. which contain only the minimaly required information which
is necessary to build the vDSO. These new headers are included from
the kernel headers and the vDSO specific files.
- Enhancements to the generic vDSO library allowing more fine grained
control over the compiled in code, further reducing architecture
specific storage and preparing for adopting the generic library by
PPC.
- Cleanup and consolidation of the exit related code in posix CPU
timers.
- Small cleanups and enhancements here and there
Drivers:
- The obligatory new drivers: Ingenic JZ47xx and X1000 TCU support
- Correct the clock rate of PIT64b global clock
- setup_irq() cleanup
- Preparation for PWM and suspend support for the TI DM timer
- Expand the fttmr010 driver to support ast2600 systems
- The usual small fixes, enhancements and cleanups all over the
place"

Updates for the interrupt subsystem:
Treewide:
- Cleanup of setup_irq() which is not longer required because the
memory allocator is available early. Most cleanup changes come
through the various maintainer trees, so the final removal of
setup_irq() is postponed towards the end of the merge window.
Core:
- Protection against unsafe invocation of interrupt handlers and unsafe
interrupt injection including a fixup of the offending PCI/AER error
injection mechanism.
Invoking interrupt handlers from arbitrary contexts, i.e. outside of
an actual interrupt, can cause inconsistent state on the fragile
x86 interrupt affinity changing hardware trainwreck.
Drivers:
- Second wave of support for the new ARM GICv4.1
- Multi-instance support for Xilinx and PLIC interrupt controllers
- CPU-Hotplug support for PLIC
- The obligatory new driver for X1000 TCU
- Enhancements, cleanups and fixes all over the place

Pull scheduler updates from Ingo Molnar:
"The main changes in this cycle are:
- Various NUMA scheduling updates: harmonize the load-balancer and
NUMA placement logic to not work against each other. The intended
result is better locality, better utilization and fewer migrations.
- Introduce Thermal Pressure tracking and optimizations, to improve
task placement on thermally overloaded systems.
- Implement frequency invariant scheduler accounting on (some) x86
CPUs. This is done by observing and sampling the 'recent' CPU
frequency average at ~tick boundaries. The CPU provides this data
via the APERF/MPERF MSRs. This hopefully makes our capacity
estimates more precise and keeps tasks on the same CPU better even
if it might seem overloaded at a lower momentary frequency. (As
usual, turbo mode is a complication that we resolve by observing
the maximum frequency and renormalizing to it.)
- Add asymmetric CPU capacity wakeup scan to improve capacity
utilization on asymmetric topologies. (big.LITTLE systems)
- PSI fixes and optimizations.
- RT scheduling capacity awareness fixes & improvements.
- Optimize the CONFIG_RT_GROUP_SCHED constraints code.
- Misc fixes, cleanups and optimizations - see the changelog for

Pull EFI updates from Ingo Molnar:
"The EFI changes in this cycle are much larger than usual, for two
(positive) reasons:
- The GRUB project is showing signs of life again, resulting in the
introduction of the generic Linux/UEFI boot protocol, instead of
x86 specific hacks which are increasingly difficult to maintain.
There's hope that all future extensions will now go through that
boot protocol.
- Preparatory work for RISC-V EFI support.
The main changes are:
- Boot time GDT handling changes
- Simplify handling of EFI properties table on arm64
- Generic EFI stub cleanups, to improve command line handling, file
I/O, memory allocation, etc.
- Introduce a generic initrd loading method based on calling back
into the firmware, instead of relying on the x86 EFI handover
protocol or device tree.
- Introduce a mixed mode boot method that does not rely on the x86
EFI handover protocol either, and could potentially be adopted by
other architectures (if another one ever surfaces where one
execution mode is a superset of another)
- Clean up the contents of 'struct efi', and move out everything that
doesn't need to be stored there.
- Incorporate support for UEFI spec v2.8A changes that permit
firmware implementations to return EFI_UNSUPPORTED from UEFI
runtime services at OS runtime, and expose a mask of which ones are
supported or unsupported via a configuration table.
- Partial fix for the lack of by-VA cache maintenance in the
decompressor on 32-bit ARM.
- Changes to load device firmware from EFI boot service memory
regions
- Various documentation updates and minor code cleanups and fixes"

Merge branch 'core-objtool-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull objtool updates from Ingo Molnar:
"The biggest changes in this cycle were the vmlinux.o optimizations by
Peter Zijlstra, which are preparatory and optimization work to run
objtool against the much richer vmlinux.o object file, to perform
new, whole-program section based logic. That work exposed a handful
of problems with the existing code, which fixes and optimizations are
merged here. The complete 'vmlinux.o and noinstr' work is still work
in progress, targeted for v5.8.
There's also assorted fixes and enhancements from Josh Poimboeuf.
In particular I'd like to draw attention to commit

spi/regulator: Updates for v5.7
At one point in the release cycle I managed to fat finger things and
apply some SPI fixes onto a regulator branch and merge that into the SPI
tree, then pull in a change shared with the MTD tree moving the Mediatek
quadspi driver over to become the Mediatek spi-nor driver in the SPI
tree. This has made a mess which I only just noticed while preparing
this and I can't see a sensible way to unpick things due to other
subsequent merge commits especially the pull from MTD so it looks like
the most sensible thing to do is give up and combine the two pull
requests - I hope this is OK. Sorry about this, I've changed some bits
of workflow which should hopefully help me spot such issues earlier in
future.
Fortunately both subsystems were fairly quiet this cycle, the highlights
are:
regulator:
- Support for Monoloithic Power Systems MP5416, MP8867 and MPS8869 and
Qualcomm PMI8994 and SMB208.
SPI:
- Lots of enhancements for spi-fsl-dspi, including XSPI mode support,
from Vladimir Oltean.
- Support for amlogic Meson G12A, IBM FSI, Mediatek spi-nor (moved from
MTD), NXP i.MX8Mx, Rockchip PX30, RK3308 and RK3328, and Qualcomm
Atheros AR934x/QCA95xx.

Staging/IIO driver patches for 5.7-rc1
Here is the big staging and IIO driver pull request for 5.7-rc1. We again end up deleting more code than we added here, thanks to finally getting rid of the old and obsolete wireless USB stuff, and the exfat code (which is coming in again through the vfs tree in a much cleaner version).

This has been a busy cycle for documentation work. Highlights include:
- Lots of RST conversion work by Mauro, Daniel ALmeida, and others.
Maybe someday we'll get to the end of this stuff...maybe...
- Some organizational work to bring some order to the core-api manual.
- Various new docs and additions to the existing documentation.
- Typo fixes, warning fixes, ...

Pull io_uring updates from Jens Axboe:
"Here are the io_uring changes for this merge window. Light on new
features this time around (just splice + buffer selection), lots of
cleanups, fixes, and improvements to existing support. In particular,
this contains:
- Cleanup fixed file update handling for stack fallback (Hillf)
- Re-work of how pollable async IO is handled, we no longer require
thread offload to handle that. Instead we rely using poll to drive
this, with task_work execution.
- In conjunction with the above, allow expendable buffer selection,
so that poll+recv (for example) no longer has to be a split
operation.
- Make sure we honor RLIMIT_FSIZE for buffered writes
- Add support for splice (Pavel)
- Linked work inheritance fixes and optimizations (Pavel)
- Async work fixes and cleanups (Pavel)
- Improve io-wq locking (Pavel)
- Hashed link write improvements (Pavel)
- SETUP_IOPOLL|SETUP_SQPOLL improvements (Xiaoguang)"
