apio	a9460469d9	kernel+libc+apps: Add a source parameter to the mount() system call	2023-06-25 20:35:35 +02:00
apio	54a1998d42	kernel: Also move children's parent to PID 1 in the common thread exit function	2023-06-19 12:35:31 +02:00
apio	e60b2a3d2f	kernel: Move thread exit code into a separate common function	2023-06-19 12:33:25 +02:00
apio	b4a6e4d56d	libluna/PathParser: Make dirname() and basename() static functions ... This avoids creating a PathParser to use them, which allocates memory that won't be used.	2023-06-19 11:21:58 +02:00
apio	36e6787415	kernel: Make sure addresses allocated by mmap() are ALWAYS page-aligned ... Fixes a kernel crash. Thanks a lot, sysfuzz!	2023-06-18 20:29:32 +02:00

apio	67ed18629d	kernel: Update the VM allocator for userspace to use a linked list ... This can cover the entire address space at once in a more memory-efficient way. Stress-tested using 'base64 /bin/ls' which allocates enough contiguous virtual memory to store the entirety of /bin/ls :) A couple of bugs and fixes later, here we are!	2023-06-18 01:48:48 +02:00
