[PATCH v2 1/6] libnvdimm/namespace: Make namespace size validation arch dependent
by Aneesh Kumar K.V
The page size used to map the namespace is arch dependent. For example
architectures like ppc64 use 16MB page size for direct-mapping. If the namespace
size is not aligned to the mapping page size, we can observe kernel crash
during namespace init and destroy.
This is due to kernel doing partial map/unmap of the resource range
BUG: Unable to handle kernel data access at 0xc001000406000000
Faulting instruction address: 0xc000000000090790

[daxctl PATCH] daxctl/list: Avoid memory operations without
resource data
by Dan Williams
Resource data is restricted to root-only, and "daxctl list" is likely to
be run by non-root. Skip listing memory-object details when the resource
is not available.
Otherwise, "daxctl list" from non-root emits:
libdaxctl: memblock_in_dev: dax1.0: Unable to determine resource

Your account was under attack! Change your access data!
by lucdiasgoncalves＠hotimail.com
Hello!
I have very bad news for you.
11/08/2019 - on this day I hacked your OS and got full access to your account linux-nvdimm(a)lists.01.org.
So, you can change the password, yes.. But my malware intercepts it every time.
How I made it:
In the software of the router, through which you went online, was a vulnerability.
I just hacked this router and placed my malicious code on it.
When you went online, my trojan was installed on the OS of your device.
After that, I made a full dump of your disk (I have all your address book, history of viewing sites, all files, phone numbers and addresses of all your contacts).
A month ago, I wanted to lock your device and ask for a not big amount of btc to unlock.
But I looked at the sites that you regularly visit, and I was shocked by what I saw!!!
I'm talk you about sites for adults.
I want to say - you are a BIG pervert. Your fantasy is shifted far away from the normal course!
And I got an idea....
I made a screenshot of the adult sites where you have fun (do you understand what it is about, huh?).
After that, I made a screenshot of your joys (using the camera of your device) and glued them together.
Turned out amazing! You are so spectacular!
I'm know that you would not like to show these screenshots to your friends, relatives or colleagues.
I think $937 is a very, very small amount for my silence.
Besides, I have been spying on you for so long, having spent a lot of time!
Pay ONLY in Bitcoins!
My BTC wallet: 1PgnnLkZfG4NuSU6aTK2xtJWwg9nzuCM1A
You do not know how to use bitcoins?
Enter a query in any search engine: "how to replenish btc wallet".
It's extremely easy
For this payment I give you two days (48 hours).
As soon as this letter is opened, the timer will work.
After payment, my virus and dirty screenshots with your enjoys will be self-destruct automatically.
If I do not receive from you the specified amount, then your device will be locked, and all your contacts will receive a screenshots with your "enjoys".
I hope you understand your situation.
- Do not try to find and destroy my virus! (All your data, files and screenshots is already uploaded to a remote server)
- Do not try to contact me (this is not possible, the sender is randomized automatically)
- Various security services will not help you; formatting a disk or destroying a device will not help, since your data is already on a remote server.
P.S. You are not my single victim. so, I guarantee you that I will not disturb you again after payment!
This is the word of honor hacker.
I also ask you to regularly update your antiviruses in the future. This way you will no longer fall into a similar situation.
Do not hold evil! I just do my job.
Good luck.

[GIT PULL] ACPI updates for v5.5-rc1
by Rafael J. Wysocki
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
acpi-5.5-rc1
with top-most commit 782b59711e1561ee0da06bc478ca5e8249aa8d09
Merge branch 'acpi-mm'
on top of commit 31f4f5b495a62c9a8b15b1c3581acd5efeb9af8c
Linux 5.4-rc7
to receive ACPI update for 5.5-rc1.
These update the ACPICA code in the kernel to upstream revision
20191018, add support for EFI specific purpose memory, update the
ACPI EC driver to make it work on systems with hardware-reduced ACPI,
improve ACPI-based device enumeration for some platforms, rework the
lid blacklist handling in the button driver and add more lid quirks
to it, unify ACPI _HID/_UID matching, fix assorted issues and clean
up the code and documentation.
Specifics:
- Update the ACPICA code in the kernel to upstream revision 20191018
including:
* Fixes for Clang warnings (Bob Moore).
* Fix for possible overflow in get_tick_count() (Bob Moore).
* Introduction of acpi_unload_table() (Bob Moore).
* Debugger and utilities updates (Erik Schmauss).
* Fix for unloading tables loaded via configfs (Nikolaus Voss).
- Add support for EFI specific purpose memory to optionally allow
either application-exclusive or core-kernel-mm managed access to
differentiated memory (Dan Williams).
- Fix and clean up processing of the HMAT table (Brice Goglin,
Qian Cai, Tao Xu).
- Update the ACPI EC driver to make it work on systems with
hardware-reduced ACPI (Daniel Drake).
- Always build in support for the Generic Event Device (GED) to
allow one kernel binary to work both on systems with full
hardware ACPI and hardware-reduced ACPI (Arjan van de Ven).
- Fix the table unload mechanism to unregister platform devices
created when the given table was loaded (Andy Shevchenko).
- Rework the lid blacklist handling in the button driver and add
more lid quirks to it (Hans de Goede).
- Improve ACPI-based device enumeration for some platforms based
on Intel BayTrail SoCs (Hans de Goede).
- Add an OpRegion driver for the Cherry Trail Crystal Cove PMIC
and prevent handlers from being registered for unhandled PMIC
OpRegions (Hans de Goede).
- Unify ACPI _HID/_UID matching (Andy Shevchenko).
- Clean up documentation and comments (Cao jin, James Pack, Kacper
Piwiński).
Thanks!

[ndctl PATCH v2] ndctl/list: Add 'target_node' to region and
namespace verbose listings
by Dan Williams
Historically the 'numa_node' attribute of a device has been the local,
or closest cpu numa node that can access the device. With the ACPI HMAT
and other platform descriptions of performance differentiated memory,
memory device targets may have their own numa identifier. The
target_node property indicates that target information and the effective
online numa node the memory range would receive if it were onlined.
While this property has been available to device-dax instances since
kernel commit 21c75763a3ae "device-dax: Add a 'target_node' attribute",
recent kernels have also started exporting for regions and namespaces.
Add it to the verbose listing.

[ndctl PATCH] ndctl/list: Add 'target_node' to region and namespace
verbose listings
by Dan Williams
Historically the 'numa_node' attribute of a device has been the local,
or closest cpu numa node that can access the device. With the ACPI HMAT
and other platform descriptions of performance differentiated memory,
memory device targets may have their own numa identifier. The
target_node property indicates that target information and the effective
online numa node the memory range would receive if it were onlined.
While this property has been available to device-dax instances since
kernel commit 21c75763a3ae "device-dax: Add a 'target_node' attribute",
recent kernels have also started exporting for regions and namespaces.
Add it to the verbose listing.

Security Notice. linux-nvdimm@lists.01.org was hacked! Change your password now!
by zohir.sari＠groupe-chiali.com
Dear user of lists.01.org!
I am a spyware software developer.
Your account has been hacked by me in the summer of 2019.
The hacking was carried out using a hardware vulnerability through which you went online (Cisco router, vulnerability CVE-2019-12643).
I went around the security system in the router, installed an exploit there.
When you went online, my exploit downloaded my malicious code (rootkit) to your device.
This is driver software, I constantly updated it, so your antivirus is silent all time.
Since then I have been following you (I can connect to your device via the VNC protocol).
That is, I can see absolutely everything that you do, view and download your files and any data to yourself.
I also have access to the camera on your device, and I periodically take photos and videos with you.
At the moment, I have harvested a solid dirt... on you...
I saved all your email and chats from your messangers. I also saved the entire history of the sites you visit.
I note that it is useless to change the passwords. My malware update passwords from your accounts every times.
I know what you like hard funs (adult sites).
Oh, yes .. I'm know your secret life, which you are hiding from everyone.
Oh my God, what are your like... I saw THIS ... Oh, you dirty naughty person ... :)
I took photos and videos of your most passionate funs with adult content, and synchronized them in real time with the image of your camera.
Believe it turned out very high quality!
So, to the business!
I'm sure you don't want to show these files and visiting history to all your contacts.
Transfer $968 to my Bitcoin cryptocurrency wallet: 1CDKLgab6xUnAwP5q5x3jdDy8978Bt2iCZ
Just copy and paste the wallet number when transferring.
If you do not know how to do this - ask Google.
My system automatically recognizes the translation.
As soon as the specified amount is received, all your data will be destroyed from my server, and the rootkit will be automatically removed from your system.
Do not worry, I really will delete everything, since I am 'working' with many people who have fallen into your position.
You will only have to inform your provider about the vulnerabilities in the router so that other hackers will not use it.
Since opening this letter you have 48 hours.
If funds not will be received, after the specified time has elapsed, the disk of your device will be formatted,
and from my server will automatically send email and sms to all your contacts with compromising material.
P.S. Do not try to contact me (this is impossible, sender's address was randomly generated).
I advise you to remain prudent and not engage in nonsense (all files on my server).
Good luck!
