With this series opendir, readdir, closedir are implemented for ext4. These functions are needed for the UEFI sub-system to interact with the ext4 file system.
To reduce code growth the functions are reused to implement the ls command for ext4.

Applied to local tree/v2-tidy-test-dir, thanks!
Am I sleeping?
int ext4fs_opendir(const char *dirname, struct fs_dir_stream **dirsp) { struct ext4_dir_stream *dirs = NULL;
Thank you for your review.
We should not set a value that we do not use.
struct ext2fs_node *dir = NULL; int ret; *dirsp = NULL; dirs = calloc(1, sizeof(struct ext4_dir_stream)); if (!dirs) return -ENOMEM; dirs->dirname = strdup(dirname); if (!dirs->dirname) {Yes this line in my code is incorrect.
We need to use valgrind in unit test or we need some code analys to automate this process. We are always looking for memory leaks in uboot in exit path or we need to have alloction funciton that automatic free the memory when we go in error path
Michael
free(dirs); return -ENOMEM; } ret = ext4fs_find_file(dirname, &ext4fs_root->diropen, &dir,FILETYPE_DIRECTORY);
if (ret == 1) { ret = 0; *dirsp = (struct fs_dir_stream *)dirs; } else { ret = -ENOENT; free(dirs->dirname); free(dirs);Yes, we should avoid a memory leak here.
I will send a patch.
Best regards
Heinrich
} if (dir) ext4fs_free_node(dir, &ext4fs_root->diropen); return ret;}
Should not be like this?
