android-cloexec-pipe2
|
||
|
|
=====================
|
||
|
|
|
||
|
|
This check ensures that pipe2() is called with the O_CLOEXEC flag. 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:
|
||
|
|
|
||
|
|
.. code-block:: c++
|
||
|
|
|
||
|
|
pipe2(pipefd, O_NONBLOCK);
|
||
|
|
|
||
|
|
Suggested replacement:
|
||
|
|
|
||
|
|
.. code-block:: c++
|
||
|
|
|
||
|
|
pipe2(pipefd, O_NONBLOCK | O_CLOEXEC);
