android-cloexec-epoll-create1¶

epoll_create1() should include EPOLL_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:

epoll_create1(0);

// becomes

epoll_create1(EPOLL_CLOEXEC);
