android-cloexec-socket
|
|
======================
|
|
|
|
``socket()`` should include ``SOCK_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:
|
|
|
|
.. code-block:: c++
|
|
|
|
socket(domain, type, SOCK_STREAM);
|
|
|
|
// becomes
|
|
|
|
socket(domain, type, SOCK_STREAM | SOCK_CLOEXEC);
