shutdown. Also another part of the change about shuffling the call
order looks suspicious; the azx_stop_chip() call disables the CORB /

Nvidia proprietary driver doesn't support runtime power management, so
when a user only wants to use the integrated GPU, it's a common practice

runtime suspended. At the end of runtime suspension the port uses
platform power management to disable power through _OFF method of power
resource, which is listed by _PR3.
After commit
b516ea586d71 ("PCI: Enable NVIDIA HDA controllers"), when
the dGPU comes with an HDA function, the HDA won't be suspended if the
dGPU is unbound, so the power resource can't be turned off by its
upstream port driver.
Commit
37a3a98ef601 ("ALSA: hda - Enable runtime PM only for

bound, to keep APU's HDA working.
However, HDA on dGPU isn't that useful if dGPU is not bound to any

function, to disable the power source to save lots of power.

The IRQ target is automatically selected from a list of AMDTP streams,
thus users of AMDTP domain should add an AMDTP stream for IT context
at least.
The reason to select IT context as IRQ target is that the IT context

ALSA: firewire-lib: tune the minimum available size of PCM period
In IEC 61883-1/6, one isoc packet can transfer events up to the value of
syt interval. This comes from the interval of isoc cycle. As 1394 OHCI
controller can generate hardware IRQ per isoc packet, the interval is
calculated as 125 usec.
In IEC 61883-1/6, two ways of transmission is described; blocking and
non-blocking methods. In blocking method, the sequence of packet includes
'empty' or 'NODATA' packets which include no events. In non-blocking
method, the number of events per packet is variable up to the syt
interval.
This commit uses double of the value of syt interval as minimum available
size of PCM period due to the above protocol design.

ALSA: hda - Force runtime PM on Nvidia HDMI codecs
Przemysław Kopa reports that since commit
b516ea586d71 ("PCI: Enable
NVIDIA HDA controllers"), the discrete GPU Nvidia GeForce GT 540M on his
2011 Samsung laptop refuses to runtime suspend, resulting in a power
regression and excessive heat.
Rivera Valdez witnesses the same issue with a GeForce GT 525M (GF108M)
of the same era, as does another Arch Linux user named "R0AR" with a
more recent GeForce GTX 1050 Ti (GP107M).
The commit exposes the discrete GPU's HDA controller and all four codecs
on the controller do not set the CLKSTOP and EPSS bits in the Supported
Power States Response. They also do not set the PS-ClkStopOk bit in the
Get Power State Response. hda_codec_runtime_suspend() therefore does
not call snd_hdac_codec_link_down(), which prevents each codec and the
PCI device from runtime suspending.
The same issue is present on some AMD discrete GPUs and we addressed it
by forcing runtime PM despite the bits not being set, see commit
57cb54e53bdd ("ALSA: hda - Force to link down at runtime suspend on
ATI/AMD HDMI").
Do the same for Nvidia HDMI codecs.

In current implementation, when opening a PCM substream, it's needed to

The number of PCM substreams on AMDTP streams in domain is recorded in

This is better because the count is incremented in pcm.hw_params earlier

This commit replaces the check with the substream count and the value for

no MIDI substream is multiplexed into AMDTP stream.
I note that Fireface AMDTP protocol has a quirk that tx stream includes
blank isochronous cycle. The packet for blank cycle is equivalent to
empty or NODATA packet in IEC 61883-6, thus the protocol is similar to
blocking transmission method of IEC 61883-6. On the other hand, rx
stream adopts non-blocking transmission method. Although the difference
of transmission method between tx/rx streams precisely brings different
timing for a certain amount of events due to their different calculation
for data blocks per packet, it's possible to approximate enough amount
of events mostly has the same timing. Actually current ALSA IEC 61883-1/6

incremented in pcm.hw_params earlier than pcm.trigger.
This idea has one issue because it's incremented for MIDI substreams as
well. In current implementation, for a case that any MIDI substream run
and a PCM substream is going to start, PCM application to start the PCM
substream can decide hardware parameters by restart packet streaming.
Just checking the substream count can brings regression.
Now AMDTP domain structure has a member for the size of PCM period in
PCM substream which starts AMDTP streams in domain. When the value has
zero and the substream count is greater than 1, it means that any MIDI
substream starts AMDTP streams in domain. Usage of the value can resolve
the above issue.
This commit replaces the check with the substream count and the value for
the size of PCM period.

elf: don't use MAP_FIXED_NOREPLACE for elf executable mappings
In commit
4ed28639519c ("fs, elf: drop MAP_FIXED usage from elf_map") we
changed elf to use MAP_FIXED_NOREPLACE instead of MAP_FIXED for the
executable mappings.
Then, people reported that it broke some binaries that had overlapping
segments from the same file, and commit
ad55eac74f20 ("elf: enforce
MAP_FIXED on overlaying elf segments") re-instated MAP_FIXED for some
overlaying elf segment cases. But only some - despite the summary line
of that commit, it only did it when it also does a temporary brk vma for
one obvious overlapping case.
Now Russell King reports another overlapping case with old 32-bit x86
binaries, which doesn't trigger that limited case. End result: we had
better just drop MAP_FIXED_NOREPLACE entirely, and go back to MAP_FIXED.
Yes, it's a sign of old binaries generated with old tool-chains, but we
do pride ourselves on not breaking existing setups.
This still leaves MAP_FIXED_NOREPLACE in place for the load_elf_interp()
and the old load_elf_library() use-cases, because nobody has reported
breakage for those. Yet.
Note that in all the cases seen so far, the overlapping elf sections
seem to be just re-mapping of the same executable with different section
attributes. We could possibly introduce a new MAP_FIXED_NOFILECHANGE
flag or similar, which acts like NOREPLACE, but allows just remapping
the same executable file using different protection flags.
It's not clear that would make a huge difference to anything, but if
people really hate that "elf remaps over previous maps" behavior, maybe
at least a more limited form of remapping would alleviate some concerns.
Alternatively, we should take a look at our elf_map() logic to see if we
end up not mapping things properly the first time.
In the meantime, this is the minimal "don't do that then" patch while
people hopefully think about it more.

Merge branch 'readdir' (readdir speedup and sanity checking)
This makes getdents() and getdents64() do sanity checking on the
pathname that it gives to user space. And to mitigate the performance
impact of that, it first cleans up the way it does the user copying, so
that the code avoids doing the SMAP/PAN updates between each part of the
dirent structure write.
I really wanted to do this during the merge window, but didn't have
time. The conversion of filldir to unsafe_put_user() is something I've
had around for years now in a private branch, but the extra pathname
checking finally made me clean it up to the point where it is mergable.
It's worth noting that the filename validity checking really should be a
bit smarter: it would be much better to delay the error reporting until
the end of the readdir, so that non-corrupted filenames are still
returned. But that involves bigger changes, so let's see if anybody
actually hits the corrupt directory entry case before worrying about it
further.

Linus Torvalds [Sat, 5 Oct 2019 18:32:52 +0000 (11:32 -0700)]
Make filldir[64]() verify the directory entry filename is valid
This has been discussed several times, and now filesystem people are
talking about doing it individually at the filesystem layer, so head
that off at the pass and just do it in getdents{64}().
This is partially based on a patch by Jann Horn, but checks for NUL
bytes as well, and somewhat simplified.
There's also commentary about how it might be better if invalid names
due to filesystem corruption don't cause an immediate failure, but only
an error at the end of the readdir(), so that people can still see the
filenames that are ok.
There's also been discussion about just how much POSIX strictly speaking
requires this since it's about filesystem corruption. It's really more
"protect user space from bad behavior" as pointed out by Jann. But
since Eric Biederman looked up the POSIX wording, here it is for context:
"From readdir:
The readdir() function shall return a pointer to a structure
representing the directory entry at the current position in the
directory stream specified by the argument dirp, and position the
directory stream at the next entry. It shall return a null pointer
upon reaching the end of the directory stream. The structure dirent
defined in the <dirent.h> header describes a directory entry.
From definitions:
3.129 Directory Entry (or Link)
An object that associates a filename with a file. Several directory
entries can associate names with the same file.
...
3.169 Filename
A name consisting of 1 to {NAME_MAX} bytes used to name a file. The
characters composing the name may be selected from the set of all
character values excluding the slash character and the null byte. The
filenames dot and dot-dot have special meaning. A filename is
sometimes referred to as a 'pathname component'."
Note that I didn't bother adding the checks to any legacy interfaces
that nobody uses.
Also note that if this ends up being noticeable as a performance
regression, we can fix that to do a much more optimized model that
checks for both NUL and '/' at the same time one word at a time.
We haven't really tended to optimize 'memchr()', and it only checks for
one pattern at a time anyway, and we really _should_ check for NUL too
(but see the comment about "soft errors" in the code about why it
currently only checks for '/')
See the CONFIG_DCACHE_WORD_ACCESS case of hash_name() for how the name
lookup code looks for pathname terminating characters in parallel.

Convert filldir[64]() from __put_user() to unsafe_put_user()
We really should avoid the "__{get,put}_user()" functions entirely,
because they can easily be mis-used and the original intent of being
used for simple direct user accesses no longer holds in a post-SMAP/PAN
world.
Manually optimizing away the user access range check makes no sense any
more, when the range check is generally much cheaper than the "enable
user accesses" code that the __{get,put}_user() functions still need.
So instead of __put_user(), use the unsafe_put_user() interface with
user_access_{begin,end}() that really does generate better code these
days, and which is generally a nicer interface. Under some loads, the
multiple user writes that filldir() does are actually quite noticeable.
This also makes the dirent name copy use unsafe_put_user() with a couple
of macros. We do not want to make function calls with SMAP/PAN

architecture uses "asm goto" for unsafe_put_user() like x86 does.
Note that this doesn't bother with the legacy cases. Nobody should use

kheaders: make headers archive reproducible
In commit
43d8ce9d65a5 ("Provide in-kernel headers to make
extending kernel easier") a new mechanism was introduced, for kernels
>=5.2, which embeds the kernel headers in the kernel image or a module
and exposes them in procfs for use by userland tools.
The archive containing the header files has nondeterminism caused by
header files metadata. This patch normalizes the metadata and utilizes
KBUILD_BUILD_TIMESTAMP if provided and otherwise falls back to the
default behaviour.
In commit
f7b101d33046 ("kheaders: Move from proc to sysfs") it was
modified to use sysfs and the script for generation of the archive was

scripts/setlocalversion: clear local variable to make it work for sh
Geert Uytterhoeven reports a strange side-effect of commit
858805b336be
("kbuild: add $(BASH) to run scripts with bash-extension"), which
inserts the contents of a localversion file in the build directory twice.
[Steps to Reproduce]
$ echo bar > localversion
$ mkdir build
$ cd build/
$ echo foo > localversion
$ make -s -f ../Makefile defconfig include/config/kernel.release
$ cat include/config/kernel.release
5.4.0-rc1foofoobar
This comes down to the behavior change of local variables.
The 'man sh' on my Ubuntu machine, where sh is an alias to dash,
explains as follows:
When a variable is made local, it inherits the initial value and
exported and readonly flags from the variable with the same name
in the surrounding scope, if there is one. Otherwise, the variable
is initially unset.
[Test Code]
foo ()
{
local res
echo "res: $res"
}
res=1
foo
[Result]
$ sh test.sh
res: 1
$ bash test.sh
res:
So, scripts/setlocalversion correctly works only for bash in spite of
its hashbang being #!/bin/sh. Nobody had noticed it before because
CONFIG_SHELL was previously set to bash almost all the time.
Now that CONFIG_SHELL is set to sh, we must write portable and correct
code. I gave the Fixes tag to the commit that uncovered the issue.
Clear the variable 'res' in collect_files() to make it work for sh
(and it also works on distributions where sh is an alias to bash).

namespace: fix namespace.pl script to support relative paths
The namespace.pl script does not work properly if objtree is not set to
an absolute path. The do_nm function is run from within the find
function, which changes directories.
Because of this, appending objtree, $File::Find::dir, and $source, will
return a path which is not valid from the current directory.
This used to work when objtree was set to an absolute path when using
"make namespacecheck". It appears to have not worked when calling
./scripts/namespace.pl directly.
This behavior was changed in
7e1c04779efd ("kbuild: Use relative path
for $(objtree)", 2014-05-14)
Rather than fixing the Makefile to set objtree to an absolute path, just
fix namespace.pl to work when srctree and objtree are relative. Also fix
the script to use an absolute path for these by default.
Use the File::Spec module for this purpose. It's been part of perl
5 since 5.005.
The curdir() function is used to get the current directory when the
objtree and srctree aren't set in the environment.
rel2abs() is used to convert possibly relative objtree and srctree
environment variables to absolute paths.
Finally, the catfile() function is used instead of string appending
paths together, since this is more robust when joining paths together.
