2021-04-02Added kernel section clear/protect after initMarvin Borner
This is a huge security improvement as it prevents potential exploits of using or modifying internal kernel functions or data.

By using the nonnull attribute and replace buffer-overflow-prone functions like strcpy, strcat and sprintf by strlcpy, strlcat and snprintf.

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.

2021-03-29Added recursive widget locatorMarvin Borner
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.
2021-03-25Implemented window movingMarvin Borner

2021-03-21Cleaner shared memory implementationMarvin Borner
2021-03-21Hardened syscallsMarvin Borner
2021-03-21Added basic shared memory supportMarvin Borner
This will be improved soon. It's very insecure right now.
2021-03-20Reimplemented memory range validationMarvin Borner
2021-03-20Merged ELF loadingMarvin Borner
2021-03-20LGTM!Marvin 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...
