e2b5c1bfdd uptime: Use clock_gettime instead of reading from /dev/uptime 2022-10-30 09:09:03 +01:00

688a640a16 Kernel: Add the clock_gettime syscall, which replaces clock as it can be used for more stuff 2022-10-30 09:07:59 +01:00

a9da58421f su: do not pass out-of-bounds argv to execv when argc is 1 2022-10-29 20:13:40 +02:00
d1e4bc5504 Kernel: Use framebuffer virtual address instead of physical address
Just found out bootboot.fb_ptr was the physical address, not virtual.
That explains why we were getting page faults while writing to the physical address of the framebuffer. (we were in a user address space when doing so)
So this should probably make the system much more stable!!

It asks for a password only if you are not root, obviously.

7d0e442cde libc: Add /etc/passwd and the pwd.h API
getpwent, getpwnam, getpwuid... they may have been a pain to implement but once they work they're awesome :)

Right now passwords are stored in plaintext in the world-readable passwd file, which is not good.
But I don't have any sort of hashing implemented so it'll stay that way for now.

d93a4062a2 libc: Do not use the heavy variadic syscall() function for wrappers
That function is meant more for user programs, and should still be rarely used, since it's not portable.
Instead, we already know the number of arguments. We just call __lc_fast_syscallN, which also sets errno.
