* [PATCH] powerpc/kasan: Fix stack overflow by increasing THREAD_SHIFT
From: Christophe Leroy @ 2020-04-08 15:58 UTC (permalink / raw)
To: Benjamin Herrenschmidt, Paul Mackerras, Michael Ellerman,

Cc: linuxppc-dev, linux-kernel
When CONFIG_KASAN is selected, the stack usage is increased.
In the same way as x86 and arm64 architectures, increase
THREAD_SHIFT when CONFIG_KASAN is selected.
Fixes: 2edb16efc899 ("powerpc/32: Add KASAN support")

Hi Jon,
I have a large list of patches this time for the Documentation/. So, I'm
starting sending them a little earier. Yet, those are meant to be applied
after the end of the merge window. They're based on today's linux-next,
with has only 49 patches pending to be applied upstream touching
Documentation/, so I don't expect much conflicts if applied early at
-rc cycle.
Most of the patches here were already submitted, but weren't
merged yet at next. So, it seems that nobody picked them yet.
In any case, most of those patches here are independent from
the others.
The number of doc build warnings have been rising with time.
The main goal with this series is to get rid of most Sphinx warnings
and other errors.
Patches 1 to 5: fix broken references detected by this tool:
./scripts/documentation-file-ref-check
The other patches fix other random errors due to tags being
mis-interpreted or mis-used.
You should notice that several patches touch kernel-doc scripts.
IMHO, some of the warnings are actually due to kernel-doc being
too pedantic. So, I ended by improving some things at the toolset,
in order to make it smarter. That's the case of those patches:
docs: scripts/kernel-doc: accept blank lines on parameter description
scripts: kernel-doc: accept negation like !@var
scripts: kernel-doc: proper handle @foo->bar()
The last 4 patches address problems with PDF building.
The first one address a conflict that will rise during the merge
window: Documentation/media will be removed. Instead of
just drop it from the list of PDF documents, I opted to drop the
entire list, as conf.py will auto-generate from the sources:
docs: LaTeX/PDF: drop list of documents
Also, right now, PDF output is broken due to a namespace conflict
at I2c (two pdf outputs there will have the same name).
docs: i2c: rename i2c.svg to i2c_bus.svg
The third PDF patch is not really a fix, but it helps a lot to identify
if the build succeeded or not, by placing the final PDF output on
a separate dir:
docs: Makefile: place final pdf docs on a separate dir
Finally, the last one solves a bug since the first supported Sphinx
version, with also impacts PDF output: basically while nested tables
are valid with ReST notation, the toolset only started supporting
it on PDF output since version 2.4:
docs: update recommended Sphinx version to 2.4.4
PS.: Due to the large number of C/C, I opted to keep a smaller
set of C/C at this first e-mail (only e-mails with "L:" tag from
MAINTAINERS file).

Randy means that ZSMALLOC_PGTABLE_MAPPING is a bool, so I think hch's patch
is wrong ... if ZSMALLOC is 'm' then ZSMALLOC_PGTABLE_MAPPING would become
'n' instead of 'y'.

My mm/Kconfig has:
config ZSMALLOC
tristate "Memory allocator for compressed pages"
depends on MMU
which I think means it can be modular, no?

* [Bug 207129] PowerMac G4 DP (5.6.2 debug kernel + inline KASAN) freezes shortly after booting with "do_IRQ: stack overflow: 1760"
From: bugzilla-daemon @ 2020-04-08 14:55 UTC (permalink / raw)
To: linuxppc-dev
In-Reply-To: <bug-207129-206035@https.bugzilla.kernel.org/>
https://bugzilla.kernel.org/show_bug.cgi?id=207129
--- Comment #5 from Christophe Leroy (christophe.leroy@c-s.fr) ---
Ok, so as a summary:
- With CONFIG_THREAD_SHIFT = 13 and CONFIG_DEBUG_STACKOVERFLOW, the system gets
stuck
- With CONFIG_THREAD_SHIFT = 13 and without CONFIG_DEBUG_STACKOVERFLOW, stack
overflow is not really detected until it gets into kernel text !!!
- With CONFIG_THREAD_SHIFT = 14 it runs fine
- With CONFIG_VMAP_STACK, the automatic restart doesn't work
- Without CONFIG_VMAP_STACK, the automatic restart works
So I'll send a patch to set CONFIG_THREAD_SHIFT to 14 when CONFIG_KASAN is
selected. x86 and arm64 already do that.
And I'll try to investigate the other points when I have time.

* usb: gadget: fsl_udc_core: Checking for a failed platform_get_irq() call in fsl_udc_probe()
From: Markus Elfring @ 2020-04-08 14:15 UTC (permalink / raw)

Hello,
I have taken another look at the implementation of the function “fsl_udc_probe”.
A software analysis approach points the following source code out for
further development considerations.
https://elixir.bootlin.com/linux/v5.6.2/source/drivers/usb/gadget/udc/fsl_udc_core.c#L2443
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/usb/gadget/udc/fsl_udc_core.c?id=f5e94d10e4c468357019e5c28d48499f677b284f#n2442
udc_controller->irq = platform_get_irq(pdev, 0);
if (!udc_controller->irq) {
ret = -ENODEV;
goto err_iounmap;
}
The software documentation is providing the following information
for the used programming interface.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/base/platform.c?id=f5e94d10e4c468357019e5c28d48499f677b284f#n221
https://elixir.bootlin.com/linux/v5.6.2/source/drivers/base/platform.c#L202
“…
* Return: IRQ number on success, negative error number on failure.
…”
Would you like to reconsider the shown condition check?

Markus

Is there a reason for not having those dts files in mainline then?
If nothing else, it would document what machines are still being
used with future kernels.
Also, if that's the only 405 based product that is still relevant with
a 5.7+ kernel, it may be useful to know at which point they
move to a 476 core and stop updating kernels on the old ones.

Both hwsync and sync are extended mnemonics to 'sync 0'.
I just replaced hwsync for sync on this patch, but I'm

A merge glitch?

I reckon for arm64 we can do similar in our <asm/pgtable.h>:
#define pgprot_nx(pgprot_t prot) \
__pgprot_modify(prot, 0, PTE_PXN)
... matching the style of our existing pgprot_*() modifier helpers.
