The commit
f14f1806e329fe92d01f15c22a384702f0cb4ae0 introduced CHASE_SAFE
flag. When the flag is set, then `fd_parent` may not be properly closed.
This sets `_cleanup_close_` attribute to `fd_parent`.
Thus, now `fd_parent` is always closed properly.
/* Two dots? Then chop off the last bit of what we already found out. */
if (path_equal(first, "/..")) {
_cleanup_free_ char *parent = NULL;
- int fd_parent = -1;
+ _cleanup_close_ int fd_parent = -1;
/* If we already are at the top, then going up will not change anything. This is in-line with
* how the kernel handles this. */
safe_close(fd);
fd = fd_parent;
+ fd_parent = -1;
continue;
