I have no ideas halp

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!
2021-04-16New elegant I/O blocking solutionMarvin Borner
This is done using an internal scheduler syscall (127). Very nice!
2021-04-15Basic block/unblockMarvin Borner
2021-04-13Started IO dev managerMarvin Borner
2021-04-10Some changes here and thereMarvin Borner
2021-04-10Gave procs own kernel stack (TSS)Marvin Borner
2021-04-06Made 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
2021-04-03Enabled 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.
2021-04-02Replaced 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.
2021-03-21Cleaner shared memory implementationMarvin Borner
2021-03-21Hardened syscallsMarvin Borner
2021-03-20Reimplemented memory range validationMarvin Borner

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.

2020-09-11Removed wait syscall - whoopsidoo!Marvin Borner
2020-09-07Added wait syscall.Marvin Borner
This makes a process sleep until it receives a new message (no polling!). I thought that this will result in performance improvements but I haven't noticed any, yet. Maybe I'll remove this again in the future..
