android-cloexec-pipe

This check detects usage of pipe(). Using pipe() is not recommended, pipe2() is the suggested replacement. The check also adds the O_CLOEXEC flag that marks the file descriptor to be closed in child processes. Without this flag a sensitive file descriptor can be leaked to a child process, potentially into a lower-privileged SELinux domain.

Examples:

pipe(pipefd);

Suggested replacement:

pipe2(pipefd, O_CLOEXEC);
