Bananymous	275a730485	LibELF: We use BAN::Vector<uint8_t> as elf storage ... This is made possible by the dynamic kmalloc	2023-06-18 23:29:23 +03:00
Bananymous	c7ec19c25c	Kernel: Add basic Credentials for the system ... Now filesystem access/open, etc confirm that you have access for rwxs	2023-06-11 20:06:06 +03:00
Bananymous	801025ad7b	Kernel: Big commit. Rewrite ELF loading code ... We now load ELF files to VirtualRanges instead of using kmalloc. We have only a fixed 1 MiB kmalloc for big allocations and this allows loading files even when they don't fit in there. This caused me to rewrite the whole ELF loading process since the loaded ELF is not in memory mapped by every process. Virtual ranges allow you to zero out the memory and to copy into them from arbitary byte buffers.	2023-06-09 00:37:43 +03:00
Bananymous	80d9f6131b	Kernel/LibC: move file offset back to kernel ... This makes keeping track of offsets easier and more proper	2023-05-26 22:31:21 +03:00
Bananymous	729ff267d7	LibC: add function declarations to sys/stat.h	2023-05-11 15:11:33 +03:00
Bananymous	ff2e2937a5	Kernel: Remove offset from OpenFileDescriptor ... This is now handled on the libc side. There might be reasons to have it in kernel side, but for simplicity's sake I'm moving it to libc for now :)	2023-05-09 20:31:22 +03:00
Bananymous	850ff93940	LibELF: Add 32 bit support	2023-04-22 19:00:18 +03:00
Bananymous	ef0263e32d	LibELF: Header printing can now be turned off	2023-04-22 15:34:09 +03:00
Bananymous	4588e25d27	LibELF: ELF now has methods for accessing more attributes ... You can now access the program headers and the memory itself	2023-04-22 15:31:05 +03:00
Bananymous	7d57d2fcfb	LibELF: remove unused file	2023-04-19 17:32:12 +03:00
Bananymous	d63716db96	Kernel: Process is not reference counted any more ... This was not necessary and it made things needlessly complicated	2023-04-19 00:34:18 +03:00
Bananymous	998ae511a3	LibELF: Start implementing elf library	2023-04-18 10:18:15 +03:00
