I have no ideas halp
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...
2021-05-03Fixed TSSMarvin Borner
2021-04-30Some small fixes here and thereMarvin Borner
2021-04-30Added MBR driver and better disk creationMarvin Borner
2021-04-29Alright!Marvin Borner
2021-04-29Multiboot/Grub progressMarvin Borner
2021-04-28Started conversion to Grub (#17)Marvin Borner
Yes, the CI won't like this.
2021-04-27Huge compositor, timer and yielding improvementsMarvin Borner
2021-04-26Added VMMouse support and improved PS/2 mouseMarvin Borner
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!
2021-04-17Added I/O bus implementation for efficient IPCMarvin 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!
2021-04-15Basic block/unblockMarvin Borner
2021-04-14Implemented some I/O interfacesMarvin Borner
2021-04-14Even more I/O - started new PS/2 driverMarvin Borner
2021-04-13Started IO dev managerMarvin Borner
2021-04-10Some changes here and thereMarvin Borner
2021-04-10Gave procs own kernel stack (TSS)Marvin Borner
2021-04-09Added readable/writable checksMarvin Borner
2021-04-08Renamed ext2 functionsMarvin 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
2021-04-05Fixed some minor bugsMarvin Borner
2021-04-05Added new randomization featuresMarvin Borner
2021-04-05Made kernel elf-bootableMarvin Borner

2021-04-03Enabled SMAP/SMEP protectionsMarvin Borner
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.
2021-04-02Mapped .text and .rodata readonlyMarvin Borner
2021-04-02Replaced target macrosMarvin Borner
2021-04-02Fixed serious race condition exploitsMarvin Borner
2021-04-02Added memory leak detectorMarvin Borner
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.
2021-03-28Added 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.
2021-03-24Huge GUI improvementsMarvin 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.

2021-02-26Started UBSan and stack-smashing check supportMarvin Borner
2021-02-25Added some debugging featuresMarvin Borner
I've tried to track down the bugs with kvm and q35 but I didn't manage to do it - yet! I'll probably look into it soon.
2021-02-25Applied even more warning flags!Marvin Borner
Fixing all the warnings wasn't that easy actually..
2021-02-25Added *many* static keywordsMarvin Borner
2021-02-21Activated SSE/FPU features for better performanceMarvin Borner
2021-02-18Switched to default lodepng versionMarvin Borner
This should be a bit faster and less buggy

It's a mess right now..
2021-02-16Okay!Marvin Borner
