8d46c9bbe2 Kernel, libc: Fix a big bug in printf()
Every time printf flushes the buffer to us in sprintf() or snprintf(), we call strncat to append the data.

But we want to start from the beginning in the first flush. What if there was data already there?
Well, we just append to the old data. Which is not good, and breaks snprintf()'s maximum size policy.

This fix sets the first byte of str to NULL, to avoid this.

324fb42ee2 libc: Add support for the new time functionality in the kernel 2022-10-30 09:08:29 +01:00
32e09d3417 libc: Stub out more functionality so part of binutils builds 2022-10-29 09:39:12 +02:00
702cc0442c endpwent: Close all opened instances of /etc/passwd, including those used by getpwuid() and getpwnam() 2022-10-28 21:02:55 +02:00
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.

8eb986df63 libc: Add program_invocation_name
This is a GNU extension, but I'm fine with adding it to libc.
It's guarded by the _GNU_SOURCE feature test macro anyways.

78d72c2f0c Kernel, libc: Add a getdents() system call
This is meant to be a low-level interface to implement dirent.h on top of.
