meta-comment, should we by default do this on a kernel.org domain so
that no specific distro has to worry about hosing this type of web
service?
Also, do you have the backend source for this to show how anyone can
host it themselves as well? We can't add features to the kernel that no
one but closed-source implementations will use for obvious reasons.
I've made a proof of concept backend here:
https://github.com/kdj0c/panic_report/
And the javascript to decode the kmsg trace is here (under MIT licence):
https://github.com/kdj0c/panic_report/blob/main/docs/panic_report.js
It uses the pako js library to uncompress the zlib data, which is also
under MIT/Zlib licence https://github.com/nodeca/pako/
If kernel.org want to host a default service for that, that would be
great. It can be linked with https://bugzilla.kernel.org to easily
create a bug, or look for similar bugs.
