rnbd: no need to set bi_end_io in rnbd_bio_map_kern
Since we always set bi_end_io after call rnbd_bio_map_kern, so the setting in rnbd_bio_map_kern is redundant.

rnbd: remove rnbd_dev_submit_io
The function only has one caller, so let's open code it in process_rdma. Another bonus is we can avoid push/pop stack, since we need to pass 8 arguments to rnbd_dev_submit_io.

md-cluster: Fix potential error pointer dereference in resize_bitmaps()
The error handling calls md_bitmap_free(bitmap) which checks for NULL
but will Oops if we pass an error pointer. Let's set "bitmap" to NULL
on this error path.

block: check queue's limits.discard_granularity in __blkdev_issue_discard()
If create a loop device with a backing NVMe SSD, current loop device driver doesn't correctly set its queue's limits.discard_granularity and leaves it as 0. If a discard request at LBA 0 on this loop device, in __blkdev_issue_discard() the calculated req_sects will be 0, and a zero length discard request will trigger a BUG() panic in generic block layer code at block/blk-mq.c:563.

hmm related patches for 5.9
This series adds reporting of the page table order from hmm_range_fault()
and some optimization of migrate_vma():
- Report the size of the page table mapping out of hmm_range_fault(). This
makes it easier to establish a large/huge/etc mapping in the device's
page table.
- Allow devices to ignore the invalidations during migration in cases
where the migration is not going to change pages. For instance migrating
pages to a device does not require the device to invalidate pages
already in the device.
- Update nouveau and hmm_tests to use the above

This is the bulk of GPIO changes for the v5.9 kernel cycle:
Core changes:
- Introduce the for_each_requested_gpio() macro to help in
dependent code all over the place. Also patch a few locations
to use it while we are at it.
- Split out the sysfs code into its own file.
- Split out the character device code into its own file, then
make a set of refactorings and improvements to this code.
We are setting the stage to revamp the userspace API a bit
in the next cycle.
- Fix a whole slew of kerneldoc that was wrong or missing.
New drivers:
- The PCA953x driver now supports the PCAL9535.
Driver improvements:
- A host of incremental modernizations and improvements to the
PCA953x driver.
- Incremental improvements to the Xilinx Zynq driver.
- Some improvements to the GPIO aggregator driver.
- I ran all over the place switching all threaded and other
drivers requesting their own IRQ while using the core
GPIO IRQ helpers to pass the GPIO irq chip as a template
instead of calling the explicit set-up functions. Next merge
window we may retire the old code altogether.

Driver core changes for 5.9-rc1
Here is the "big" set of changes to the driver core, and some drivers
using the changes, for 5.9-rc1.
"Biggest" thing in here is the device link exposure in sysfs, to help
to tame the madness that is SoC device tree representations and driver
interactions with it.
Other stuff in here that is interesting is:
- device probe log helper so that drivers can report problems in
a unified way easier.
- devres functions added
- DEVICE_ATTR_ADMIN_* macro added to make it harder to write
incorrect sysfs file permissions
- documentation cleanups
- ability for debugfs to be present in the kernel, yet not
exposed to userspace. Needed for systems that want it
enabled, but do not trust users, so they can still use some
kernel functions that were otherwise disabled.
- other minor fixes and cleanups
The patches outside of drivers/base/ all have acks from the respective
subsystem maintainers to go through this tree instead of theirs.
All of these have been in linux-next with no reported issues.

mmc: mediatek: make function msdc_cqe_disable() static
The sparse tool complains as follows:
drivers/mmc/host/mtk-sd.c:2269:6: warning:
symbol 'msdc_cqe_disable' was not declared. Should it be static?
This function is not used outside of mtk-sd.c, so this commit
marks it static.

It's been a busy cycle for documentation - hopefully the busiest for a
while to come. Changes include:
- Some new Chinese translations
- Progress on the battle against double words words and non-HTTPS URLs
- Some block-mq documentation
- More RST conversions from Mauro. At this point, that task is
essentially complete, so we shouldn't see this kind of churn again for a
while. Unless we decide to switch to asciidoc or something...:)
- Lots of typo fixes, warning fixes, and more.

Support for FSGSBASE. Almost 5 years after the first RFC to support it,
this has been brought into a shape which is maintainable and actually works. This final version was done by Sasha Levin who took it up after Intel dropped the ball. Sasha discovered that the SGX (sic!) offerings out there ship rogue kernel modules enabling FSGSBASE behind the kernels back which opens an instantanious unpriviledged root hole. The FSGSBASE instructions provide a considerable speedup of the context switch path and enable user space to write GSBASE without kernel interaction. This enablement requires careful handling of the exception entries which go through the paranoid entry path as they cannot longer rely on the assumption that user GSBASE is positive (as enforced via prctl() on non FSGSBASE enabled systemn). All other entries (syscalls, interrupts and exceptions) can still just utilize SWAPGS unconditionally when the entry comes from user space. Converting these entries to use FSGSBASE has no benefit as SWAPGS is only marginally slower than WRGSBASE and locating and retrieving the kernel GSBASE value is not a free operation either. The real benefit of RD/WRGSBASE is the avoidance of the MSR reads and writes. The changes come with appropriate selftests and have held up in field testing against the (sanitized) Graphene-SGX driver. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl8pGnoTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoTYJD/9873GkwvGcc/Vq/dJH1szGTgFftPyZ c/Y9gzx7EGBPLo25BS820L+ZlynzXHDxExKfCEaD10TZfe5XIc1vYNR0J74M2NmK IBgEDstJeW93ai+rHCFRXIevhpzU4GgGYJ1MeeOgbVMN3aGU1g6HfzMvtF0fPn8Y n6fsLZa43wgnoTdjwjjikpDTrzoZbaL1mbODBzBVPAaTbim7IKKTge6r/iCKrOjz Uixvm3g9lVzx52zidJ9kWa8esmbOM1j0EPe7/hy3qH9DFo87KxEzjHNH3T6gY5t6 NJhRAIfY+YyTHpPCUCshj6IkRudE6w/qjEAmKP9kWZxoJrvPCTWOhCzelwsFS9b9 gxEYfsnaKhsfNhB6fi0PtWlMzPINmEA7SuPza33u5WtQUK7s1iNlgHfvMbjstbwg MSETn4SG2/ZyzUrSC06lVwV8kh0RgM3cENc/jpFfIHD0vKGI3qfka/1RY94kcOCG AeJd0YRSU2RqL7lmxhHyG8tdb8eexns41IzbPCLXX2sF00eKNkVvMRYT2mKfKLFF q8v1x7yuwmODdXfFR6NdCkGm9IU7wtL6wuQ8Nhu9UraFmcXo6X6FLJC18FqcvSb9 jvcRP4XY/8pNjjf44JB8yWfah0xGQsaMIKQGP4yLv4j6Xk1xAQKH1MqcC7l1D2HN 5Z24GibFqSK/vA== =QaAN -----END PGP SIGNATURE----- Merge tag 'x86-fsgsbase-2020-08-04' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fsgsbase from Thomas Gleixner: "Support for FSGSBASE.

entry/exit functionality based on the recent X86 effort to ensure correctness of entry/exit vs. RCU and instrumentation. As this functionality and the required entry/exit sequences are not architecture specific, sharing them allows other architectures to benefit instead of copying the same code over and over again.

The conversion of x86 comes in a seperate pull request which obviously is based on this branch. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl8pCYsTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoY1MD/9VNT5ehFZwDBxX8EUY7QcBAPiR1yql XgHVbfhUe9Zta4q6eXn1A6IGpperY+2TLdU1Gm0aVXGAZwt5WeM7mAMIGpOXqibK oRZcTGOdxovY/548H3EWmrPAeJRKtpGDOF9MqmDfSBI4PXPyu9oKTRbWtRztgZa2 f8CALSXRCWRztZwI4xZKInC78p564Bz4x98wu/CbSZ7iTid/FIm4BcrH+eSbhLGt LUjKp74zDl4HncJUUCRv1RZmfiK4N0XwgfNLqHlkNu2ep1sJ92t4YuqyQC5acUUp L+fzlMdG1elFi5HlCmOTLrZIRerOyhqxfiWsfMiqapSvWdjW05HJ2AwyQbyhXMTt iLe8Rds0kcGGvCjt2X7S1mJFrPmV8QlrpQkOh9l/R5ekMsxG2jbzt7ZCbEASNtBp +riLLEQcl+IOej5zDAUUcdpWA8/ODlY9RZwv0vW9kR3v6SUtBdoS9YHSgbh5rgOt USEJwipyNLsD5tUWEIAZhw6moMzFFkO512O23bUgAwYKJx/KVYaBGWKq2nGLjqLc njqR3NX568/0ixPy3Vmhf3fde8Izp/CgK12gJxCj7sM77W8nvjD2IaqRsW2nK5Tk nD5yCLpolcl5vU8Bu0G9ln+jabKwbZHBOGFnqAUW0AKKv7jTkjILEoZbNVrd8MOG Sj/asNIIKw3LPg== =y2Ew -----END PGP SIGNATURE----- Merge tag 'core-entry-2020-08-04' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull generic kernel entry/exit code from Thomas Gleixner: "Generic implementation of common syscall, interrupt and exception entry/exit functionality based on the recent X86 effort to ensure correctness of entry/exit vs RCU and instrumentation.

Time, timers and related driver updates:
- Prevent unnecessary timer softirq invocations by extending the tracking
of the next expiring timer in the timer wheel beyond the existing NOHZ
functionality. The tracking overhead at enqueue time is within the
noise, but on sensitive workloads the avoidance of the soft interrupt

Pull close_range() implementation from Christian Brauner:
"This adds the close_range() syscall. It allows to efficiently close a
range of file descriptors up to all file descriptors of a calling
task.
This is coordinated with the FreeBSD folks which have copied our
version of this syscall and in the meantime have already merged it in
April 2019:
https://reviews.freebsd.org/D21627
https://svnweb.freebsd.org/base?view=revision&revision=359836
The syscall originally came up in a discussion around the new mount
API and making new file descriptor types cloexec by default. During
this discussion, Al suggested the close_range() syscall.
First, it helps to close all file descriptors of an exec()ing task.
This can be done safely via (quoting Al's example from [1] verbatim):
/* that exec is sensitive */
unshare(CLONE_FILES);
/* we don't want anything past stderr here */
close_range(3, ~0U);
execve(....);
The code snippet above is one way of working around the problem that
file descriptors are not cloexec by default. This is aggravated by the
fact that we can't just switch them over without massively regressing
userspace. For a whole class of programs having an in-kernel method of
closing all file descriptors is very helpful (e.g. demons, service
managers, programming language standard libraries, container managers
etc.).
Second, it allows userspace to avoid implementing closing all file
descriptors by parsing through /proc/<pid>/fd/* and calling close() on
each file descriptor and other hacks. From looking at various
large(ish) userspace code bases this or similar patterns are very
common in service managers, container runtimes, and programming
language runtimes/standard libraries such as Python or Rust.
In addition, the syscall will also work for tasks that do not have
procfs mounted and on kernels that do not have procfs support compiled
in. In such situations the only way to make sure that all file
descriptors are closed is to call close() on each file descriptor up
to UINT_MAX or RLIMIT_NOFILE, OPEN_MAX trickery.
Based on Linus' suggestion close_range() also comes with a new flag
CLOSE_RANGE_UNSHARE to more elegantly handle file descriptor dropping
right before exec. This would usually be expressed in the sequence:
unshare(CLONE_FILES);
close_range(3, ~0U);
as pointed out by Linus it might be desirable to have this be a part
of close_range() itself under a new flag CLOSE_RANGE_UNSHARE which
gets especially handy when we're closing all file descriptors above a
certain threshold.
Test-suite as always included"

Pull checkpoint-restore updates from Christian Brauner:
"This enables unprivileged checkpoint/restore of processes.
Given that this work has been going on for quite some time the first
sentence in this summary is hopefully more exciting than the actual
final code changes required. Unprivileged checkpoint/restore has seen
a frequent increase in interest over the last two years and has thus
been one of the main topics for the combined containers &
checkpoint/restore microconference since at least 2018 (cf. [1]).
Here are just the three most frequent use-cases that were brought forward:
- The JVM developers are integrating checkpoint/restore into a Java
VM to significantly decrease the startup time.
- In high-performance computing environment a resource manager will
typically be distributing jobs where users are always running as
non-root. Long-running and "large" processes with significant
startup times are supposed to be checkpointed and restored with
CRIU.
- Container migration as a non-root user.
In all of these scenarios it is either desirable or required to run
without CAP_SYS_ADMIN. The userspace implementation of
checkpoint/restore CRIU already has the pull request for supporting
unprivileged checkpoint/restore up (cf. [2]).
To enable unprivileged checkpoint/restore a new dedicated capability
CAP_CHECKPOINT_RESTORE is introduced. This solution has last been
discussed in 2019 in a talk by Google at Linux Plumbers (cf. [1]
"Update on Task Migration at Google Using CRIU") with Adrian and
Nicolas providing the implementation now over the last months. In
essence, this allows the CRIU binary to be installed with the
CAP_CHECKPOINT_RESTORE vfs capability set thereby enabling
unprivileged users to restore processes.
To make this possible the following permissions are altered:
- Selecting a specific PID via clone3() set_tid relaxed from userns
CAP_SYS_ADMIN to CAP_CHECKPOINT_RESTORE.
- Selecting a specific PID via /proc/sys/kernel/ns_last_pid relaxed
from userns CAP_SYS_ADMIN to CAP_CHECKPOINT_RESTORE.
- Accessing /proc/pid/map_files relaxed from init userns
CAP_SYS_ADMIN to init userns CAP_CHECKPOINT_RESTORE.
- Changing /proc/self/exe from userns CAP_SYS_ADMIN to userns
CAP_CHECKPOINT_RESTORE.
Of these four changes the /proc/self/exe change deserves a few words
because the reasoning behind even restricting /proc/self/exe changes
in the first place is just full of historical quirks and tracking this
down was a questionable version of fun that I'd like to spare others.
In short, it is trivial to change /proc/self/exe as an unprivileged
user, i.e. without userns CAP_SYS_ADMIN right now. Either via ptrace()
or by simply intercepting the elf loader in userspace during exec.
Nicolas was nice enough to even provide a POC for the latter (cf. [3])
to illustrate this fact.
The original patchset which introduced PR_SET_MM_MAP had no
permissions around changing the exe link. They too argued that it is
trivial to spoof the exe link already which is true. The argument
brought up against this was that the Tomoyo LSM uses the exe link in
tomoyo_manager() to detect whether the calling process is a policy
manager. This caused changing the exe links to be guarded by userns
CAP_SYS_ADMIN.
All in all this rather seems like a "better guard it with something
rather than nothing" argument which imho doesn't qualify as a great
security policy. Again, because spoofing the exe link is possible for
the calling process so even if this were security relevant it was
broken back then and would be broken today. So technically, dropping
all permissions around changing the exe link would probably be
possible and would send a clearer message to any userspace that relies
on /proc/self/exe for security reasons that they should stop doing
this but for now we're only relaxing the exe link permissions from
userns CAP_SYS_ADMIN to userns CAP_CHECKPOINT_RESTORE.
There's a final uapi change in here. Changing the exe link used to
accidently return EINVAL when the caller lacked the necessary
permissions instead of the more correct EPERM. This pr contains a
commit fixing this. I assume that userspace won't notice or care and
if they do I will revert this commit. But since we are changing the
permissions anyway it seems like a good opportunity to try this fix.
With these changes merged unprivileged checkpoint/restore will be
possible and has already been tested by various users"

Pull fork cleanups from Christian Brauner:
"This is cleanup series from when we reworked a chunk of the process
creation paths in the kernel and switched to struct
{kernel_}clone_args.
High-level this does two main things:
- Remove the double export of both do_fork() and _do_fork() where
do_fork() used the incosistent legacy clone calling convention.
Now we only export _do_fork() which is based on struct
kernel_clone_args.
- Remove the copy_thread_tls()/copy_thread() split making the
architecture specific HAVE_COYP_THREAD_TLS config option obsolete.
This switches all remaining architectures to select
HAVE_COPY_THREAD_TLS and thus to the copy_thread_tls() calling
convention. The current split makes the process creation codepaths
more convoluted than they need to be. Each architecture has their own
copy_thread() function unless it selects HAVE_COPY_THREAD_TLS then it
has a copy_thread_tls() function.
The split is not needed anymore nowadays, all architectures support
CLONE_SETTLS but quite a few of them never bothered to select
HAVE_COPY_THREAD_TLS and instead simply continued to use copy_thread()
and use the old calling convention. Removing this split cleans up the
process creation codepaths and paves the way for implementing clone3()
on such architectures since it requires the copy_thread_tls() calling
convention.
After having made each architectures support copy_thread_tls() this
series simply renames that function back to copy_thread(). It also
switches all architectures that call do_fork() directly over to
_do_fork() and the struct kernel_clone_args calling convention. This
is a corollary of switching the architectures that did not yet support
it over to copy_thread_tls() since do_fork() is conditional on not
supporting copy_thread_tls() (Mostly because it lacks a separate
argument for tls which is trivial to fix but there's no need for this
function to exist.).
The do_fork() removal is in itself already useful as it allows to to
remove the export of both do_fork() and _do_fork() we currently have
in favor of only _do_fork(). This has already been discussed back when
we added clone3(). The legacy clone() calling convention is - as is
probably well-known - somewhat odd:
#
# ABI hall of shame
#
config CLONE_BACKWARDS
config CLONE_BACKWARDS2
config CLONE_BACKWARDS3
that is aggravated by the fact that some architectures such as sparc
follow the CLONE_BACKWARDSx calling convention but don't really select
the corresponding config option since they call do_fork() directly.
So do_fork() enforces a somewhat arbitrary calling convention in the
first place that doesn't really help the individual architectures that
deviate from it. They can thus simply be switched to _do_fork()
enforcing a single calling convention. (I really hope that any new
architectures will __not__ try to implement their own calling
conventions...)
Most architectures already have made a similar switch (m68k comes to
mind).
Overall this removes more code than it adds even with a good portion
of added comments. It simplifies a chunk of arch specific assembly
either by moving the code into C or by simply rewriting the assembly.
Architectures that have been touched in non-trivial ways have all been
actually boot and stress tested: sparc and ia64 have been tested with
Debian 9 images. They are the two architectures which have been
touched the most. All non-trivial changes to architectures have seen
acks from the relevant maintainers. nios2 with a custom built
buildroot image. h8300 I couldn't get something bootable to test on
but the changes have been fairly automatic and I'm sure we'll hear
people yell if I broke something there.
All other architectures that have been touched in trivial ways have
been compile tested for each single patch of the series via git rebase
-x "make ..." v5.8-rc2. arm{64} and x86{_64} have been boot tested
even though they have just been trivially touched (removal of the
HAVE_COPY_THREAD_TLS macro from their Kconfig) because well they are
basically "core architectures" and since it is trivial to get your
hands on a useable image"

Last cycle setns() was changed to support attaching to multiple namespaces atomically. This requires all namespaces to have a point of no return where they can't fail anymore. Specifically, <namespace-type>_install() is allowed to perform permission checks and install the namespace into the new struct nsset that it has been given but it is not allowed to make visible changes to the affected task. Once <namespace-type>_install() returns, anything that the given namespace type additionally requires to be setup needs to ideally be done in a function that can't fail or if it fails the failure must be non-fatal. For time namespaces the relevant functions that fell into this category were timens_set_vvar_page() and vdso_join_timens(). The latter could still fail although it didn't need to. This function is only implemented for vdso_join_timens() in current mainline. As discussed on-list (cf. [1]), in order to make setns() support time namespaces when attaching to multiple namespaces at once properly we changed vdso_join_timens() to always succeed. So vdso_join_timens() replaces the mmap_write_lock_killable() with mmap_read_lock(). Please note that arm is about to grow vdso support for time namespaces (possibly this merge window). We've synced on this change and arm64 also uses mmap_read_lock(), i.e. makes vdso_join_timens() a function that can't fail. Once the changes here and the arm64 changes have landed, vdso_join_timens() should be turned into a void function so it's obvious to callers and implementers on other architectures that the expectation is that it can't fail. We didn't do this right away because it would've introduced unnecessary merge conflicts between the two trees for no major gain. As always, tests included" [1]: https://lore.kernel.org/lkml/20200611110221.pgd3r5qkjrjmfqa2@wittgenstein * tag 'threads-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: tests: add CLONE_NEWTIME setns tests nsproxy: support CLONE_NEWTIME with setns() timens: add timens_commit() helper timens: make vdso_join_timens() always succeed |

hwmon: (adc128d818) Fix advanced configuration register init
If the operation mode is non-zero and an external reference voltage is set, first the operation mode is written to the advanced configuration register, followed by the externel reference enable bit, resetting the configuration mode to 0. To fix this, first compose the value of the advanced configuration register based on the configuration mode and the external reference voltage. The advanced configuration register is then written to the device, if it is different from the default register value (0x0).

Pull execve updates from Eric Biederman: "During the development of v5.7 I ran into bugs and quality of implementation issues related to exec that could not be easily fixed because of the way exec is implemented. So I have been diggin into exec and cleaning up what I can. This cycle I have been looking at different ideas and different implementations to see what is possible to improve exec, and cleaning the way exec interfaces with in kernel users. Only cleaning up the interfaces of exec with rest of the kernel has managed to stabalize and make it through review in time for v5.9-rc1 resulting in 2 sets of changes this cycle. - Implement kernel_execve - Make the user mode driver code a better citizen With kernel_execve the code size got a little larger as the copying of parameters from userspace and copying of parameters from userspace is now separate. The good news is kernel threads no longer need to play games with set_fs to use exec. Which when combined with the rest of Christophs set_fs changes should security bugs with set_fs much more difficult" * 'exec-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (23 commits) exec: Implement kernel_execve exec: Factor bprm_stack_limits out of prepare_arg_pages exec: Factor bprm_execve out of do_execve_common exec: Move bprm_mm_init into alloc_bprm exec: Move initialization of bprm->filename into alloc_bprm exec: Factor out alloc_bprm exec: Remove unnecessary spaces from binfmts.h umd: Stop using split_argv umd: Remove exit_umh bpfilter: Take advantage of the facilities of struct pid exit: Factor thread_group_exited out of pidfd_poll umd: Track user space drivers with struct pid bpfilter: Move bpfilter_umh back into init data exec: Remove do_execve_file umh: Stop calling do_execve_file umd: Transform fork_usermode_blob into fork_usermode_driver umd: Rename umd_info.cmdline umd_info.driver_name umd: For clarity rename umh_info umd_info umh: Separate the user mode driver and the user mode helper support umh: Remove call_usermodehelper_setup_file. ... |

hwmon: (i5k_amb, vt8231) Drop uses of pci_read_config_*() return value
The return value of pci_read_config_*() may not indicate a device error. However, the value read by these functions is more likely to indicate this kind of error. This presents two overlapping ways of reporting errors and complicates error checking. It is possible to move to one single way of checking for error if the dependency on the return value of these functions is removed, then it can later be made to return void. Remove all uses of the return value of pci_read_config_*(). Check the actual value read for ~0. In this case, ~0 is an invalid value thus it indicates some kind of error.
