android-cloexec-inotify-init1¶
inotify_init1() should include IN_CLOEXEC in its type argument to avoid the file descriptor leakage. Without this flag, an opened sensitive file would remain open across a fork+exec to a lower-privileged SELinux domain.
Examples:
inotify_init1(IN_NONBLOCK);
// becomes
inotify_init1(IN_NONBLOCK | IN_CLOEXEC);
