   getsockcreatecon_raw    ( 3 )

получить или установить контекст безопасности SELinux, используемый для создания новых помеченных сокетов (get or set the SELinux security context used for creating a new labeled sockets)

Имя (Name)

getsockcreatecon, setsockcreatecon - get or set the SELinux
       security context used for creating a new labeled sockets

Синопсис (Synopsis)

#include <selinux/selinux.h>

int getsockcreatecon(char **con);

int getsockcreatecon_raw(char **con);

int setsockcreatecon(char *context);

int setsockcreatecon_raw(char *context);


Описание (Description)

getsockcreatecon() retrieves the context used for creating a new
       labeled network socket.  This returned context should be freed
       with freecon(3) if non-NULL.  getsockcreatecon() sets *con to
       NULL if no sockcreate context has been explicitly set by the
       program (i.e. using the default policy behavior).

setsockcreatecon() sets the context used for creating a new labeled network sockets NULL can be passed to setsockcreatecon() to reset to the default policy behavior. The sockcreate context is automatically reset after the next execve(2), so a program doesn't need to explicitly sanitize it upon startup.

setsockcreatecon() can be applied prior to library functions that internally perform an file creation, in order to set an file context on the objects.

getsockcreatecon_raw() and setsockcreatecon_raw() behave identically to their non-raw counterparts but do not perform context translation.

Note: Signal handlers that perform a setsockcreatecon() must take care to save, reset, and restore the sockcreate context to avoid unexpected behavior.

Note: Contexts are thread specific.
