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

2021-04-14Even more I/O - started new PS/2 driverMarvin 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

2021-04-02Added 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.

2021-04-02Replaced target macrosMarvin Borner
2021-04-02Fixed serious race condition exploitsMarvin 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

2021-01-08Major IDE/ATA driver rewriteMarvin Borner
This adds non-hardcoded multi-disk support. I just need to remove the boot/load.c loader and fix the max bootloader ext2 loading size. After that's done I'll try running it on real hardware.
