We don't want everyone peeking at kernel symbols.

2022-11-06 17:16:08 +01:00
44815b08c7
Kernel: Use copy_from_user() and copy_to_user() in read/write
...
This is huge. Finally, we can do proper reads/writes with invalid addresses, or big buffers.
2022-11-06 15:19:23 +01:00
04ae97a6ec
libc: Add difftime()
2022-11-06 15:09:38 +01:00

libc: Rename fold() to lowercase() in strcasecmp and strncasecmp
2022-11-06 14:45:58 +01:00
da182f1c2f
libc: Add mktemp() and mkdtemp(), along with a test for mktemp
2022-11-05 18:07:45 +01:00
b2fb740d99
Kernel: Refuse to mkdir any directory named . or ..
2022-11-05 12:09:01 +01:00

libc: Exit with -errno if we fail initialization
2022-11-05 11:56:31 +01:00
9ab3ab7c40
Kernel: Show init's exit status before restarting
2022-11-05 11:56:16 +01:00
b63a9f5ba9
Kernel: Improve strdup_from_user and add copy to and from user
...
Still a bit funky, that's why we're not using it in read() and write() yet.
2022-11-05 11:54:55 +01:00
67f536cf91
Kernel: Split number-parsing code into a separate file
2022-11-05 10:50:58 +01:00
d0efc106b0
Kernel: Add UBSAN (Undefined Behaviour Sanitizer)
2022-11-05 10:47:18 +01:00
ffcaac0ca3
Kernel: Add validate_user_write() and validate_user_read()
...
Not at copy_from_user and copy_to_user yet, but an improvement over blindly using physical memory.
2022-11-04 22:46:48 +01:00

Remove the .elf suffix from the kernel filename
2022-11-03 20:44:37 +01:00
e5b2641019
Kernel: Enforce W^X when loading executables
...
From now on, if an executable contains segments that
want to be loaded as both writable and executable,
we refuse and abort with ENOEXEC.
2022-11-03 20:28:54 +01:00
2c08de044f
Kernel, libc: Add support for querying the framebuffer's scanline via ioctl()
2022-11-03 20:20:22 +01:00

libc: Support %i in printf()
...
Which is the same as %d.
2022-11-03 16:53:19 +01:00

libc: Stub out rename()
2022-11-03 16:52:41 +01:00
0fd31698b2
Kernel: Accept not opened file descriptors in dup2()
...
This involves renaming the descriptor_from_fd function to the more appropriately named
open_descriptor_from_fd (since we check if the descriptor was opened and error out otherwise),
and creating a new function that does not verify that the file descriptor was opened.
2022-11-03 16:52:21 +01:00

...
It tells you the resolution of your screen :)
2022-11-02 21:00:23 +01:00
249c79f8a3
Kernel, libc: Add ioctl()
...
Right now, only the framebuffer supports this system call, to query its dimensions.
2022-11-02 20:59:42 +01:00
feab66c0d3
Kernel: Remove the paint() system call
...
That was a very old one from back in the old days. Now that the framebuffer is finally a device file,
and it can be memory-mapped by user programs for more performance,
this syscall is MORE than obsolete.
2022-11-02 20:35:06 +01:00
