From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Manjaro distribution is introducing a system for sending telemetry about the system (lemmy.ml)

The developers of the Manjaro Linux distribution, built on the basis of Arch Linux and aimed at beginners, announced the beginning of testing a new service MDD (Manjaro Data Donor), designed to collect statistics about the system and send it to the external server of the project. The author of the MDD intended to enable telemetry by default (opt-out), but the decision has not yet been approved and, judging by the objections of some developers and users, it is likely that telemetry will be offered as an option requiring prior consent of the user (a request to enable telemetry is proposed to be added to the greeting interface after the first download).

The report includes data such as host name, kernel version, desktop component versions, detailed information about hardware and drivers involved, screen size and resolution information, network device MAC addresses, disk serial numbers, disk partition data, information about the number of running processes and installed packages, versions of basic packages such as systemd, gcc, bash and PipeWire.

The sent data is stored on the project server in the ClickHouse database and visualized using the Grafana platform. The IP addresses of users are not stored, and the hash from the /etc/machine-id file is used as the system identifier.

Аccording to the code https://github.com/manjaro/mdd/blob/master/mdd.py#L40 sends everything.

I get the usefulness of technical telemetry such as kernel version, RAM, disk space, processor type, etc... but NIC MAC? HDD serial? WTF?

[–] [email protected] 12 points 3 weeks ago (1 children)

Those are absolutely ways of covertly identifying your device while technically not counting as "personal information" under privacy laws.

[–] [email protected] 5 points 3 weeks ago (1 children)

Serial numbers are hardly covert though... but yeah.

[–] [email protected] 6 points 3 weeks ago

The point is that it's a loophole in privacy laws so they don't have to outright tell people that they collect personal or identifying information. So they can legally mislead people by claiming it's anonymous telemetry in hopes that users don't actually look into it or understand the implications.

Yeah that makes no sense lol. Who needs MAC addresses to debug and fix bugs? No one.

[–] [email protected] 5 points 3 weeks ago

I said elsewhere, I hope this is just some way to track changes over time per user.

But they need to take an anonymous hash of some non changing data or create an install id that is used for this and nothing else (e.g it identifies a unique user but not the person or hardware behind the user).

Too much identifying info is just pushed around like we shouldn't care, it's become a real problem.

The first three octets of a MAC specify the manufacturer of a NIC chipset. That could come in handy for driver debugging.

Manufacturers and firmware versions of storage devices? You can make the argument; perhaps it would have helped figure out the SSD firmware bugs years ago.

But stuff like whether or not you have video capture card or your current system temperature stats? Nah.. that's getting into "identifiable information as toxic waste" territory.

[–] [email protected] 1 points 2 weeks ago* (last edited 2 weeks ago) (1 children)

Yeah, so take the vendor and device id and be done?

Why should they need my unique ID/MAC?

[–] [email protected] 1 points 2 weeks ago (1 children)

A MAC address isn't really unique. Each has six octets, of which three refer to the manufacturer. The other three octets have at most 16,777,216 possible values. That seems like a lot but it really isn't; a MAC is supposed to be unique on a LAN, not globally. Rollovers during manufacturing happen, and collisions are rare but happen once in a while.

[–] [email protected] 2 points 2 weeks ago (1 children)

Unique enough with the other hardware IDs

And still, absolutely no reason to go further then the first octets, to have the vendor and device

Or am I missing something?

And I'm currently a happy user of Manjaro since years. But this stuff really isn't what I want to have on my system ...

[–] [email protected] 2 points 2 weeks ago (1 children)

Just defining the threat model of hardware addressing, as it stands.

I don't agree with them sending more than the first half either.

[–] [email protected] 2 points 2 weeks ago

All good, just wanted to clarify what I meant
