Stan Johnson contacted me about a regression in mainline that he observed
on his G3 Powerbooks. Using 'git bisect' we determined that this patch was
the cause of the regression, i.e. commit 4c0104a83fc3 ("powerpc/32:
Dismantle EXC_XFER_STD/LITE/TEMPLATE").
When testing 4c0104a83fc and all subsequent builds, various user processes
were liable to segfault. Here is the console log that Stan provided:

When testing a recent mainline build, 5.14.0-rc2-pmac-00323-gd8079fac1681,
PID 1 did not crash. Other processes crash instead and the kernel produces
messages like these:

We found that reducing memory with the kernel parameter 'mem=464M' would
prevent the crash.
Below are Stan's notes from the 'git bisect' run. They include an
additional failure mode that might be of interest. We've also observed
"Kernel attempted to write user page (c6207c) - exploit attempt?" and
"kernel BUG at arch/powerpc/kernel/interrupt.c:49!".

Hi, i will be able to look at that more in details next week, however
I have a few preliminary qurstions.
Can you reliabily reproduce the problem with the said commit, and can
you reliabily run without problem with the parent commit ? I'm asking
because at first look that commit doesn't bring any functionnal change.
Coukd you provide your .config ?
Could you try without CONFIG_VMAP_STACK
Thanks
Christophe

Not sure this is really the root of the problem.
Can you try again without CONFIG_VMAP_STACK ?
Thanks

With CONFIG_VMAP_STACK=y, 5.11.0-rc5-pmac-00034-g684da7628d9 hangs at
boot on the PB 3400c.
Without CONFIG_VMAP_STACK, 5.11.0-rc5-pmac-00034-g684da7628d9 boots as
expected.
I didn't re-build the Debian SID kernel, though I confirmed that the
Debian config file for 5.10.0-8-powerpc includes CONFIG_VMAP_STACK=y.
It's not clear whether removing CONFIG_VMAP_STACK would be appropriate
for other powerpc systems.
Please let me know why removing CONFIG_VMAP_STACK fixed the problem on
the PB 3400c. Should CONFIG_HAVE_ARCH_VMAP_STACK also be removed?
thanks

Oh, you're right. So this needs something like:
if (!pcidev || !(pdrv = pci_driver_of_dev(pcidev)))
or repeating the call to pci_driver_of_dev for each previous usage of
pdev->driver.
If there are no other preferences I'd got with the first approach for
v2.
Best regards and thanks for catching,
Uwe

Yes and yes. (I already asked Stan to establish those things before I
contacted the list.)

Please see attached. My understanding is that all of Stan's builds were
performed like this:
$ cp ../dot-config-powermac-5.13 .config
$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- -j4 clean olddefconfig vmlinux

Stan, would you please test the following build:
$ git checkout v5.13
$ cp ../dot-config-powermac-5.13 .config
$ scripts/config -d CONFIG_VMAP_STACK
$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- -j4 clean olddefconfig vmlinux

* [PATCH 1/2] tty: hvc: pass DMA capable memory to put_chars()
From: Xianting Tian @ 2021-08-01 5:16 UTC (permalink / raw)
To: gregkh, jirislaby, amit, arnd
Cc: Xianting Tian, linuxppc-dev, linux-kernel, virtualization
As well known, hvc backend can register its opertions to hvc backend.
the opertions contain put_chars(), get_chars() and so on.
Some hvc backend may do dma in its opertions. eg, put_chars() of
virtio-console. But in the code of hvc framework, it may pass DMA
incapable memory to put_chars() under a specific configuration, which
is explained in commit c4baad5029(virtio-console: avoid DMA from stack):
1, c[] is on stack,
hvc_console_print():
char c[N_OUTBUF] __ALIGNED__;
cons_ops[index]->put_chars(vtermnos[index], c, i);
2, ch is on stack,
static void hvc_poll_put_char(,,char ch)
{
struct tty_struct *tty = driver->ttys[0];
struct hvc_struct *hp = tty->driver_data;
int n;
do {
n = hp->ops->put_chars(hp->vtermno, &ch, 1);
} while (n <= 0);
}
Commit c4baad5029 is just the fix to avoid DMA from stack memory, which
is passed to virtio-console by hvc framework in above code. But I think
the fix is aggressive, it directly uses kmemdup() to alloc new buffer
from kmalloc area and do memcpy no matter the memory is in kmalloc area
or not. But most importantly, it should better be fixed in the hvc
framework, by changing it to never pass stack memory to the put_chars()
function in the first place. Otherwise, we still face the smae issue if
a new hvc backend using dma added in the furture.
Considering lock competition of hp->outbuf and the complicated logic in
hvc_console_print(), I didn’t use hp->outbuf, just allocate additional
memory(length N_OUTBUF) and append it to hp->outbuf.
For the issue in hvc_poll_put_char(), I use a static char to replace
the char in stack.
With the patch, we can remove the fix c4baad5029.

hvc framework will never pass stack memory to the put_chars() function,
So the calling of kmemdup() is unnecessary, remove it.

Please see the attached serial console log (four boots):
1) v5.13-mac, CONFIG_VMAP_STACK=y, mem=512M (fails)
2) v5.13-mac, CONFIG_VMAP_STACK=y, mem=384M (works)
3) v5.13-mac, CONFIG_VMAP_STACK=n, mem=512M (works)
4) v5.13-mac, CONFIG_VMAP_STACK=n, mem=384M (works)
My apologies if the extra boots were not needed (due to the time
difference, I'm trying to anticipate future requests).
Cutting and pasting Finn's commands above builds a new kernel
(5.13.0-pmac) with the following in .config:
$ fgrep VMAP .config
CONFIG_HAVE_ARCH_VMAP_STACK=y
CONFIG_VMAP_STACK=y
I'm not sure what "scripts/config -d CONFIG_VMAP_STACK" does, since
"CONFIG_VMAP_STACK=y" is in "../dot-config-powermac-5.13 .config".
1) I booted the resulting kernel on a 512M Wallstreet (WS-1) with its
default memory setting (i.e. not specifying a mem= parameter in BootX);
that boot proceed to a login prompt (serial console and fb console wdm
prompt). There were multiple errors, and the X login screen hung.
2) Repeating 1) but with "mem=384M" passed to the kernel, everything
worked as expected (X worked, no errors logged).
Next, I edited .config and changed "CONFIG_VMAP_STACK=y" to
"CONFIG_VMAP_STACK=n", then I ran:
"make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- -j4 clean
olddefconfig vmlinux"
The resulting .config does not set CONFIG_VMAP_STACK:
$ fgrep VMAP .config
CONFIG_HAVE_ARCH_VMAP_STACK=y
# CONFIG_VMAP_STACK is not set
3) Same as 1 (512M) but with CONFIG_VMAP_STACK not set in v5.13.
Everything works (no problems with X, no errors logged).
4) Same as 2 (384M) but with CONFIG_VMAP_STACK not set in v5.13.
Everything works (no problems with X, no errors logged).
Please let me know if you need anything else.
thanks for investigating this problem

This is wrong, but needed in order to avoid overlapping ranges with the
OTP area added in the next commit. A refactor of this part of the
device tree is needed: according to Wiibrew[1], this area starts at
0x0d800000 and spans 0x400 bytes (that is, 0x100 32-bit registers),
encompassing PIC and GPIO registers, amongst the ones already exposed in
this device tree, which should become children of the control@d800000
node.

Both of these consoles use the exact same two registers, even at the
same address, but the Wii U has eight banks of 128 bytes memory while
the Wii only has one, hence the two compatible strings.

* [PATCH v4 0/5] nvmem: nintendo-otp: Add new driver for the Wii and Wii U OTP
From: Emmanuel Gil Peyrot @ 2021-08-01 7:38 UTC (permalink / raw)
To: Rob Herring, linuxppc-dev, devicetree

In-Reply-To: <20210701225743.14631-1-linkmauve@linkmauve.fr>
The OTP is a read-only memory area which contains various keys and
signatures used to decrypt, encrypt or verify various pieces of storage.
Its size depends on the console, it is 128 bytes on the Wii and
1024 bytes on the Wii U (split into eight 128 bytes banks).
It can be used directly by writing into one register and reading from
the other one, without any additional synchronisation.
This series has been tested on both the Wii U (using my downstream
master-wiiu branch[1]), as well as on the Wii on mainline.
[1] https://gitlab.com/linkmauve/linux-wiiu/-/commits/master-wiiu
Changes since v1:
- Fixed the commit messages so they can be accepted by other email
servers, sorry about that.
Changes since v2:
- Switched the dt binding documentation to YAML.
- Used more obvious register arithmetic, and tested that gcc (at -O1 and
above) outputs the exact same rlwinm instructions for them.
- Use more #defines to make the code easier to read.
- Include some links to the reversed documentation.
- Avoid overlapping dt regions by changing the existing control@d800100
node to end before the OTP registers, with some bigger dt refactoring
left for a future series.
Changes since v3:
- Relicense the dt-binding documentation under GPLv2-only or
BSD-2-clauses.

While this may work, it sounds rather obscure to me, I don't think
it's a good idea
to append the buffer at the back.
If you need a separate field besides hp->outbuf, I would make that part of the
structure itself, and give it the correct alignment constraints to ensure it is
in a cache line by itself. The size of this field is a compile-time
constant, so I
don't see a need to play tricks with pointer arithmetic.
I'm not sure about the locking either: Is it possible for two CPUs to enter
hvc_console_print() at the same time, or is there locking at a higher level
already? It would be good to document this in the structure definition next
to the field.

This does not compile, and it's neither thread-safe nor dma safe if you get it
to build by renaming the variable.
