docs: cdomain.py: extend it to handle new Sphinx 3.x tags
While most of the C domain parsing is done via kernel-doc, some RST files use C domain tags directly. While several of them can be removed for Sphinx < 3.0, due to automarkup.py, and several others that could be converted into kernel-doc markups, changes like that are time-consuming, and may not fit all cases. As we already have the cdomain.py for handing backward compatibility with Sphinx versions below 3.0, let's make it more complete, in order to cover any usage of the newer tags outside kernel-doc. This way, it should be feasible to use the new tags inside the Kernel tree, without losing backward compatibility. This should allow fixing the remaining warnings with the Kernel tags.

docs: cdomain.py: add support for a new Sphinx 3.1+ tag
Since Sphinx 3.0, the C domain code was rewritten, but only after version 3.1 it got support for setting namespaces on C domains, with is something that it is required, in order to document system calls, like ioctl() and others. As part of changing the documentation subsystem to properly build with Sphinx 3.1+, add support for such new tag: .. c:namespace::" Such tag optionally replaces the optional "name" tag for functions, setting a single namespace domain for all C references found at the file. With that, it should be possible to convert existing documentation to be compatible with both Sphinx 1.x/2.x and 3.1+. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> |

scripts: kernel-doc: try to use c:function if possible
There are a few namespace clashes by using c:macro everywhere:
basically, when using it, we can't have something like:
.. c:struct:: pwm_capture
.. c:macro:: pwm_capture
So, we need to use, instead:
.. c:function:: int pwm_capture (struct pwm_device * pwm, struct pwm_capture * result, unsigned long timeout)
for the function declaration.
The kernel-doc change was proposed by Jakob Lykke Andersen here:

scripts: kernel-doc: fix line number handling
Address several issues related to pointing to the wrong line number: 1) ensure that line numbers will always be initialized When section is the default (Description), the line number is not initializing, producing this: $ ./scripts/kernel-doc --enable-lineno ./drivers/media/v4l2-core/v4l2-mem2mem.c|less **Description** #define LINENO 0 In case of streamoff or release called on any context, 1] If the context is currently running, then abort job will be called 2] If the context is queued, then the context will be removed from the job_queue Which is not right. Ensure that the line number will always be there. After applied, the result now points to the right location: **Description** #define LINENO 410 In case of streamoff or release called on any context, 1] If the context is currently running, then abort job will be called 2] If the context is queued, then the context will be removed from the job_queue 2) The line numbers for function prototypes are always + 1, because it is taken at the line after handling the prototype. Change the logic to point to the next line after the /** */ block; 3) The "DOC:" line number should point to the same line as this markup is found, and not to the next one. Probably part of the issues were due to a but that was causing the line number offset to be incremented by one, if --export were used.

scripts: kernel-doc: allow passing desired Sphinx C domain dialect
When kernel-doc is called via kerneldoc.py, there's no need to auto-detect the Sphinx version, as the Sphinx module already knows it. So, add an optional parameter to allow changing the Sphinx dialect. As kernel-doc can also be manually called, keep the auto-detection logic if the parameter was not specified. On such case, emit a warning if sphinx-build can't be found at PATH. I ended using a suggestion from Joe for using a more readable regex, instead of using a complex one with a hidden group like: m/^(\d+)\.(\d+)(?:\.?(\d+)?)/ in order to get the optional <patch> argument.

scripts: kernel-doc: don't mangle with parameter list
While kernel-doc needs to parse parameters in order to identify its name, it shouldn't be touching the type, as parsing it is very difficult, and errors happen. One current error is when parsing this parameter: const u32 (*tab)[256] Found at ./lib/crc32.c, on this function: u32 __pure crc32_be_generic (u32 crc, unsigned char const *p, size_t len, const u32 (*tab)[256], u32 polynomial); The current logic mangles it, producing this output: const u32 ( *tab That's something that it is not recognizeable. So, instead, let's push the argument as-is, and use it when printing the function prototype and when describing each argument. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> |

scripts: kernel-doc: reimplement -nofunction argument
Right now, the build system doesn't use -nofunction, as it is pretty much useless, because it doesn't consider the other output modes (extern, internal), working only with all. Also, it is limited to exclude functions. Re-implement it in order to allow excluding any symbols from the document output, no matter what mode is used. The parameter was also renamed to "-nosymbol", as it express better its meaning. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> |

scripts: kernel-doc: fix troubles with line counts
There's currently a bug with the way kernel-doc script counts line numbers that can be seen with: $ ./scripts/kernel-doc -rst -enable-lineno include/linux/math64.h >all && ./scripts/kernel-doc -rst -internal -enable-lineno include/linux/math64.h >int && diff -U0 int all --- int 2020-09-28 12:58:08.927486808 +0200 +++ all 2020-09-28 12:58:08.905486845 +0200 @@ -1 +1 @@ -#define LINENO 27 +#define LINENO 26 @@ -3 +3 @@ -#define LINENO 16 +#define LINENO 15 @@ -9 +9 @@ -#define LINENO 17 +#define LINENO 16 ... This is happening with perl version 5.30.3, but I'm not so sure if this is a perl bug, or if this is due to something else. In any case, fixing it is easy. Basically, when "-internal" parameter is used, the process_export_file() function opens the handle "IN". This makes the line number to be incremented, as the handler for the main open is also "IN". Fix the problem by using a different handler for the main open(). While here, add a missing close for it. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> |

scripts: kernel-doc: use a less pedantic markup for funcs on Sphinx 3.x
Unfortunately, Sphinx 3.x parser for c functions is too pedantic: https://github.com/sphinx-doc/sphinx/issues/8241 While it could be relaxed with some configurations, there are several corner cases that it would make it hard to maintain, and will require teaching conf.py about several macros. So, let's instead use the :c:macro notation. This will produce an output that it is not as nice as currently, but it should still be acceptable, and will provide cross-references, removing thousands of warnings when building with newer versions of Sphinx.

With Sphinx 3.x, the ".. c:type:" tag was changed to accept either: .. c:type:: typedef-like declaration .. c:type:: name Using it for other types (including functions) don't work anymore. So, there are newer tags for macro, enum, struct, union, and others, which doesn't exist on older versions. Add a check for the Sphinx version and change the produced tags accordingly.

powerpc32: don't adjust unmoved stack pointer in csum_partial_copy_generic() epilogue
A recent change to the checksum code removed usage of some extra
arguments, alongside with storage on the stack for those, and the stack
pointer no longer needed to be adjusted in the function prologue.
But a left over subtraction wasn't removed in the function epilogue,
causing the function to return with the stack pointer moved 16 bytes
away from where it should have. This corrupted local state and lead to
weird crashes.
This simply removes the leftover instruction from the epilogue.

Pin control bulk changes for the v5.10 kernel cycle
Core changes:
- NONE whatsoever, we don't even touch the core files this
time around.
New drivers:
- New driver for the Toshiba Visconti SoC.
- New subdriver for the Qualcomm MSM8226 SoC.
- New subdriver for the Actions Semiconductor S500 SoC.
- New subdriver for the Mediatek MT8192 SoC.
- New subdriver for the Microchip SAMA7G5 SoC.
Driver enhancements:
- Intel Cherryview and Baytrail cleanups and refactorings.
- Enhanced support for the Renesas R8A7790, more pins and
groups.
- Some optimizations for the MCP23S08 MCP23x17 variant.
- Some cleanups around the Actions Semiconductor subdrivers.
- A bunch of cleanups around the SH-PFC and Emma Mobile
drivers.
- The "SH-PFC" (literally SuperH pin function controller, I
think) subdirectory is now renamed to the more neutral
"renesas", as these are not very much centered around
SuperH anymore.
- Non-critical fixes for the Aspeed driver.
- Non-critical fixes for the Ingenic (MIPS!) driver.
- Fix a bunch of missing pins on the AMD pinctrl driver.

fs: fix NULL dereference due to data race in prepend_path()
Fix data race in prepend_path() with re-reading mnt->mnt_ns twice
without holding the lock.
is_mounted() does check for NULL, but is_anon_ns(mnt->mnt_ns) might
re-read the pointer again which could be NULL already, if in between
reads one of kern_unmount()/kern_unmount_array()/umount_tree() sets
mnt->mnt_ns to NULL.
This is seen in production with the following stack trace:
BUG: kernel NULL pointer dereference, address: 0000000000000048

Pull pidfd updates from Christian Brauner:
"This introduces a new extension to the pidfd_open() syscall. Users can
now raise the new PIDFD_NONBLOCK flag to support non-blocking pidfd
file descriptors. This has been requested for uses in async process
management libraries such as async-pidfd in Rust.
Ever since the introduction of pidfds and more advanced async io
various programming languages such as Rust have grown support for
async event libraries. These libraries are created to help build
epoll-based event loops around file descriptors. A common pattern is
to automatically make all file descriptors they manage to O_NONBLOCK.
For such libraries the EAGAIN error code is treated specially. When a
function is called that returns EAGAIN the function isn't called again
until the event loop indicates the the file descriptor is ready.
Supporting EAGAIN when waiting on pidfds makes such libraries just
work with little effort.
This introduces a new flag PIDFD_NONBLOCK that is equivalent to
O_NONBLOCK. This follows the same patterns we have for other (anon
inode) file descriptors such as EFD_NONBLOCK, IN_NONBLOCK,
SFD_NONBLOCK, TFD_NONBLOCK and the same for close-on-exec flags.
Passing a non-blocking pidfd to waitid() currently has no effect, i.e.
is not supported. There are users which would like to use waitid() on
pidfds that are O_NONBLOCK and mix it with pidfds that are blocking
and both pass them to waitid().
The expected behavior is to have waitid() return -EAGAIN for
non-blocking pidfds and to block for blocking pidfds without needing
to perform any additional checks for flags set on the pidfd before
passing it to waitid(). Non-blocking pidfds will return EAGAIN from
waitid() when no child process is ready yet. Returning -EAGAIN for
non-blocking pidfds makes it easier for event loops that handle EAGAIN
specially.
It also makes the API more consistent and uniform. In essence,
waitid() is treated like a read on a non-blocking pidfd or a recvmsg()
on a non-blocking socket.
With the addition of support for non-blocking pidfds we support the
same functionality that sockets do. For sockets() recvmsg() supports
MSG_DONTWAIT for pidfds waitid() supports WNOHANG. Both flags are
per-call options. In contrast non-blocking pidfds and non-blocking
sockets are a setting on an open file description affecting all
threads in the calling process as well as other processes that hold
file descriptors referring to the same open file description. Both
behaviors, per call and per open file description, have genuine
use-cases.
The interaction with the WNOHANG flag is documented as follows:
- If a non-blocking pidfd is passed and WNOHANG is not raised we
simply raise the WNOHANG flag internally. When do_wait() returns
indicating that there are eligible child processes but none have
exited yet we set EAGAIN. If no child process exists we continue
returning ECHILD.
- If a non-blocking pidfd is passed and WNOHANG is raised waitid()
will continue returning 0, i.e. it will not set EAGAIN. This ensure
backwards compatibility with applications passing WNOHANG
explicitly with pidfds"
* tag 'threads-v5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux:
tests: remove O_NONBLOCK before waiting for WSTOPPED
tests: add waitid() tests for non-blocking pidfds
tests: port pidfd_wait to kselftest harness
pidfd: support PIDFD_NONBLOCK in pidfd_open()
exit: support non-blocking pidfds

"The biggest changes are two new features for the ondisk metadata: one
to record the sizes of the inode btrees in the AG to increase
redundancy checks and to improve mount times; and a second new feature
to support timestamps until the year 2486.
We also fixed a problem where reflinking into a file that requires
synchronous writes wouldn't actually flush the updates to disk; clean
up a fair amount of cruft; and started fixing some bugs in the
realtime volume code.

- Fix some problems when readahead ios fail.
- Fix a problem where inline data pages weren't getting flushed during

- Rework iomap to support arbitrarily many blocks per page in
preparation to support THP for the page cache.
- Fix a bug in the blocksize < pagesize buffered io path where we could

when the backing page is actually up to date. This could cause us to
forget to write out dirty pages.
- Split out the generic_write_sync at the end of the directio write path

- Call inode_dio_end before trying to sync the file after a O_DSYNC
direct write (instead of afterwards) to match the behavior of the

IOMMU Updates for Linux v5.10
Including:
- ARM-SMMU Updates from Will:
- Continued SVM enablement, where page-table is shared with

- Groundwork to support integrated SMMU with Adreno GPU
- Allow disabling of MSI-based polling on the kernel
command-line
- Minor driver fixes and cleanups (octal permissions, error
messages, ...)
- Secure Nested Paging Support for AMD IOMMU. The IOMMU will
fault when a device tries DMA on memory owned by a guest. This
needs new fault-types as well as a rewrite of the IOMMU memory
semaphore for command completions.
- Allow broken Intel IOMMUs (wrong address widths reported) to
still be used for interrupt remapping.
- IOMMU UAPI updates for supporting vSVA, where the IOMMU can
access address spaces of processes running in a VM.
- Support for the MT8167 IOMMU in the Mediatek IOMMU driver.
- Device-tree updates for the Renesas driver to support r8a7742.

This feature enhances the current guest memory encryption support
called SEV by also encrypting the guest register state, making the
registers inaccessible to the hypervisor by en-/decrypting them on world
switches. Thus, it adds additional protection to Linux guests against
exfiltration, control flow and rollback attacks.
With SEV-ES, the guest is in full control of what registers the
hypervisor can access. This is provided by a guest-host exchange
mechanism based on a new exception vector called VMM Communication
Exception (#VC), a new instruction called VMGEXIT and a shared
Guest-Host Communication Block which is a decrypted page shared between
the guest and the hypervisor.
Intercepts to the hypervisor become #VC exceptions in an SEV-ES guest so
in order for that exception mechanism to work, the early x86 init code
needed to be made able to handle exceptions, which, in itself, brings
a bunch of very nice cleanups and improvements to the early boot code
like an early page fault handler, allowing for on-demand building of the
identity mapping. With that, !KASLR configurations do not use the EFI
page table anymore but switch to a kernel-controlled one.
The main part of this series adds the support for that new exchange
mechanism. The goal has been to keep this as much as possibly
separate from the core x86 code by concentrating the machinery in two
SEV-ES-specific files:
arch/x86/kernel/sev-es-shared.c
arch/x86/kernel/sev-es.c
Other interaction with core x86 code has been kept at minimum and behind
static keys to minimize the performance impact on !SEV-ES setups.

mm, oom_adj: don't loop through tasks in __set_oom_adj when not necessary
Currently __set_oom_adj loops through all processes in the system to keep
oom_score_adj and oom_score_adj_min in sync between processes sharing
their mm. This is done for any task with more that one mm_users, which
includes processes with multiple threads (sharing mm and signals).
However for such processes the loop is unnecessary because their signal
structure is shared as well.
Android updates oom_score_adj whenever a tasks changes its role
(background/foreground/...) or binds to/unbinds from a service, making it
more/less important. Such operation can happen frequently. We noticed
that updates to oom_score_adj became more expensive and after further
investigation found out that the patch mentioned in "Fixes" introduced a
regression. Using Pixel 4 with a typical Android workload, write time to
oom_score_adj increased from ~3.57us to ~362us. Moreover this regression
linearly depends on the number of multi-threaded processes running on the
system.
Mark the mm with a new MMF_MULTIPROCESS flag bit when task is created with
(CLONE_VM && !CLONE_THREAD && !CLONE_VFORK). Change __set_oom_adj to use
MMF_MULTIPROCESS instead of mm_users to decide whether oom_score_adj
update should be synchronized between multiple processes. To prevent
races between clone() and __set_oom_adj(), when oom_score_adj of the
process being cloned might be modified from userspace, we use
oom_adj_mutex. Its scope is changed to global.
The combination of (CLONE_VM && !CLONE_THREAD) is rarely used except for
the case of vfork(). To prevent performance regressions of vfork(), we
skip taking oom_adj_mutex and setting MMF_MULTIPROCESS when CLONE_VFORK is
specified. Clearing the MMF_MULTIPROCESS flag (when the last process
sharing the mm exits) is left out of this patch to keep it simple and
because it is believed that this threading model is rare. Should there
ever be a need for optimizing that case as well, it can be done by hooking
into the exit path, likely following the mm_update_next_owner pattern.
With the combination of (CLONE_VM && !CLONE_THREAD && !CLONE_VFORK) being
quite rare, the regression is gone after the change is applied.

memblock: use separate iterators for memory and reserved regions
for_each_memblock() is used to iterate over memblock.memory in a few places that use data from memblock_region rather than the memory ranges. Introduce separate for_each_mem_region() and for_each_reserved_mem_region() to improve encapsulation of memblock internals from its users.

memblock: implement for_each_reserved_mem_region() using __next_mem_region()
Iteration over memblock.reserved with for_each_reserved_mem_region() used __next_reserved_mem_region() that implemented a subset of __next_mem_region(). Use __for_each_mem_range() and, essentially, __next_mem_region() with appropriate parameters to reduce code duplication. While on it, rename for_each_reserved_mem_region() to for_each_reserved_mem_range() for consistency.
