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.	2024-02-14 11:37:06 +01:00
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.	2024-02-13 21:51:04 +01:00
Florian Fischer	beacbde52e	man: use cat as pager to print man pages This reduces the required code in man and additionally, replaces the old broken read/puts implementation. Puts expects a null-terminated string, but write does not return a null-terminted string.	2024-02-13 13:15:58 +01:00

Florian Fischer	89e6d75627	creat: set flags in opened file descriptor creat.2 is supposed to be equivalent to open.2 with the flags O_WRONLY\|O_CREAT\|O_TRUNC. However, in MentOS the fd returned by creat.2 has no flags whatsoever and is thus not writable. Set the flags of the file descriptor before returning it.	2024-01-28 21:50:30 +01:00

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)	2024-01-17 13:34:32 +01:00
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.	2024-01-17 13:16:50 +01:00
