2021-05-08Better serial managementMarvin Borner
Yay, I wrote my final information technology exam yesterday (abitur). Only english and mathematics are left now - hype!! (sorry for polluting my commit messages with useless personal news but this will affect the future of Melvix as my free time and therefore the time that I'm working on this project will increase massively once I'm finished with all my exams)
2021-05-05Debugging improvementsMarvin Borner
STILL NOT FOUND (see previous descr)
2021-05-04General fixes (see description) - closes #17Marvin Borner
Somehow the Grub conversion (or anything before/between that) seems to have caused a *very* weird memory bug involving the heap/stack/sth overflowing into the video memory which will obviously result in strange undefined behaviour when data is written to the video memory. VERY STRANGE. Well, I need to prepare for my finals (Abitur) so I don't know whether I can fix this issue in the next few days. We'll see...

2021-04-25Added range-based memory validatorMarvin Borner
2021-04-25Chu chuu, using the bus for everything now!Marvin Borner
Well, I know: bus != train. But I like trains. So I don't care. Go away!

2021-04-23Fixed makefilesMarvin Borner
2021-04-18Fixed some memory leaksMarvin Borner

This was a nice coding session. See ya tomorrow!
2021-04-17Implemented I/O pollingMarvin Borner
2021-04-16New elegant I/O blocking solutionMarvin Borner
This is done using an internal scheduler syscall (127). Very nice!

2021-04-08Renamed ext2 functionsMarvin Borner
2021-04-07Fixed wrong test exec nameMarvin Borner
2021-04-06Made exec syscall relative using app nameMarvin Borner
My plan is to implement a mobile-OS-like sandboxing using manifests and permission middlewares. Let's see if I can manage to do this without sacrificing too much performance. I'm also wondering whether I should implement open/close syscalls which would result in a cleaner block/unblock mechanism. I need to think. Hmmm.. Naa

2021-04-02Huge scheduling/proc-management improvementsMarvin Borner
2021-04-01Hardened entire systemMarvin Borner
By using the nonnull attribute and replace buffer-overflow-prone functions like strcpy, strcat and sprintf by strlcpy, strlcat and snprintf.
2021-04-01Started WM improvementsMarvin Borner

2021-03-30Replaced imagemagick with inkscapeMarvin Borner
2021-03-30Basic FEN parsing, buggy afMarvin Borner
The entire GUI system is kinda buggy and sluggish. Might need to rethink some design choices. I've got some ideas to improve everything though.

2021-03-28Fun with widgetsMarvin Borner
2021-03-28Added ring0 privileges to kernel processesMarvin Borner
This enables a more efficient idling process using the hlt instruction. The context-switching is a bit slower now, too. I have to look into that.
2021-03-28Added contribution tipsMarvin Borner
2021-03-26Renamed libsMarvin Borner
Cleaner and more flexible.

2021-03-21Added basic shared memory supportMarvin Borner
This will be improved soon. It's very insecure right now.

2021-03-20LGTM!Marvin Borner

2021-03-19Some thingsMarvin Borner
2021-03-17Awesome!Marvin Borner
2021-03-17Added offset and correct size in ext2Marvin Borner
2021-03-16This could actually workMarvin Borner

2021-03-14Some security measurementsMarvin Borner
2021-03-14Added ubsan shift overflow logMarvin Borner
2021-03-14Added memory management using pagingMarvin Borner
This was quite a roller-coaster and most things are slower now, but it works and is way more secure. I still need to implement things like shared memory for the WM/GUI system but other than that everything is supported.
2021-03-14Maaany fixes :)Marvin Borner
I don't have the motivation to write better commit messages...
