Florian Fischer 0347054fae fs: move and fix generic permission checks 
As defined by POSIX permissions are checked for the first matching class,
user, group or others.
Only the permissions of this first matching class are considered.

For example:
Consider a process running for user and group.
A file with user:group -w- rw- --- is not readable by user, and
thus not readable by the process.
However, it is readable by anyone else in the group.

Additionally, since the permission checks are generic and not exclusive
to the ext2 driver, they are moved to the vfs code.

Florian Fischer c8db92b7b7 fix str[n]len implementations 
The current implementations do not count the length of empty strings
correctly.
The following buffer content "\0foo\0" is considered a string with
length 4, because the iteration pointer is incremented before
it is dereferenced to check for a null char.

Replace the broken strlen functions with the implementation of musl libc.

 2024-02-26 09:57:46 -05:00
Florian Fischer dea54c7dae libc: prevent execvpe to search for files containing '/' 
The current implementation always searches for the file in PATH
if it is not an absolute path.
This prevents executing relative paths like ./executable.

As specified by exec(3) the p-family of exec functions only search if
the filename does not contain slash '/' characters.

Florian Fischer 44b1acf33c ext2: update the vfs_file_t length after writing 
The vfs_file_t->length field is initialized but never used afterwards.
It seams correct to updated it after the inode size possibly changed.
 2024-02-13 21:59:57 +01:00
Florian Fischer 4d4504486d ext2: write the inode back if its size is updated 
If there is enough space in an inode but the file grows the
inode is never written back to the device and thus the new size is
not persisted.

	int fd = creat("foo", 660);
	write(fd, "foo", 3); // New blocks are allocated and inode written back
	write(fd, "\n", 1); // size is adapted but not written back
	close(fd);
	// Reading the file afterwards will only return "foo".

The code snippet reproduces the bug.

This is fixed by always writing the inode back to the device if
the size is updated.
 2024-02-13 21:59:57 +01:00
Florian Fischer f7e53f9b00 ext2: do not update inode size when allocating new blocks 
New blocks for an inode are allocated when data blocks
should be written and not enough blocks are allocated yet
or during allocating new direntries in ext2_allocate_direntry.

When writing the first time to a newly created file (inode.size==0),
new blocks must be allocated and the inode size is erroneously set to
(blocks_count / fs->blocks_per_block_count) * fs->block_size
regardless of the actually written data.

	int fd = creat("foo", 0660);
	write(fd, "foo", 3);

This code snippet will create a new inode with size 4096 instead
of the correct size 3.

ext2_write_inode_data will correctly set the size to 3.
However, ext2_allocate_block called by ext2_write_inode_block will
set the inode size to 4096.

This is fixed by removing the size update during ext2_allocate_block.

Enrico Fraccaroli (Galfurian) eca55dfed8 Clean up cmake files (Part 2) 
I've kept just one cmake project, in the root directory. The
subdirectories just set up the targets.

The asm compiler is serached just one time, from the root
directory cmake file.

Global compilation flags are set in the root cmake file, and
each subdirectory cmake file sets specific flags if necessary
(e.g., programs need the -u_start specified)

Enrico Fraccaroli (Galfurian) 0b75cd9c2a Clean up cmake files (Part 1) 
I've been cleaning up the way compilation flags are passed to the targets
and there are still some changes that must be made, in the next commit.

I've also done some renaming, all_programs into programs and the same for
tests.

The gdb initialization file now is just one, populated using the find command
and using realpath to get the absolute path to the files. I've tested if the
generated gdb.run file works and it does.

SYNOPSIS
chmod MODE FILE
DESCRIPTION
chmod changes the file mode bits of the given file according to mode, which
must be an octal number representing the bit pattern for the new mode bits.
The numeric mode is from one to four octal digits (0-7), derived by adding
up the bits with values 4, 2, and 1. Omitted digits are assumed to be
leading zeros. The first digit selects the set user ID (4) and set group
ID (2) and restricted deletion or sticky (1) attributes. The second digit
selects permissions for the user who owns the file: read (4), write (2),
and execute (1); the third selects permissions for other users in the file's
group, with the same values; and the fourth for other users not in the
file's group, with the same values.
chmod never changes the permissions of symbolic links; the chmod system call
cannot change their permissions.
EXAMPLES
chmod 555 executable
Changes the mode bits of executable to r-xr-xr-x.

SYNOPSIS
chown [OWNER][:[GROUP]] FILE
DESCRIPTION
chown changes the user and/or group ownership of the given file.
If only a owner is given the file's group is not changed. If the owner
is followed by a colon and a group name (or numeric group ID), the group
ownership is changed as well. If the colon and group are given, but the
owner is omitted, only the group of the file is changed.
chown never changes the ownership of symbolic links; the chown system call
cannot change their ownership.
EXAMPLES
chown root /u
Change the owner of /u to "root".
