▲Decode kernel panic from QR Code photo (gist.github.com)
jolmg 3 hours ago [-]
For context, kernel panics seem to sometimes be encoded as a URL in the QR code by distros. The panic text is encoded as a numeric parameter. For example:

  https://jexposit.fedorapeople.org/drm-panic/#?a=x86_64&v=6.17.0-rc2+&z=64016708045408584681305161836175901065787789727173061004041671633088591186286363786562987653814347942450168430510852681524688435157911241621365859153819732690406649525043247774110913752991389170560320455163781439079986337356710273501164645667555084821480237326301207073831710176482850121513079951455217310046422632328303510474264780788030301611164774573122018172510304672562667379831349924441560360997679573341401750485619388375493[... many more digits]
That's from the QR code image at:

https://discussion.fedoraproject.org/t/f45-change-proposal-d...

This script is to decode such kernel panics without needing to provide it to an external service.

In the particular URL example, the panic is not necessarily sent to a server, because it's in a URL fragment (`#`), but still.

I think that's a really good idea! Would love to see this upstream

It is? This is drm-panic qr codes from Linux 6.12. It’s a neat feature but I’m not sure why this random implementation is particularly interesting.

Can't a phone decode a QR code natively? I don't even get what it does

This is about a second step of decoding.

Qr -> URL -> Panic Log

If you decode it and open the link, you are potentially leaking data to whoever controls the domain of the URL.

Link previews even! Just paste it into a group chat and everyone’s message clients will happily issue a GET request.

You can decode a QR code by hand. It’s usually not worth your while but it’s understandable.
