avc_context_to_sid(3) SELinux API documentation avc_context_to_sid(3)
NAME
avc_context_to_sid, avc_sid_to_context, avc_get_initial_sid - obtain and manipulate SELinux security ID's
SYNOPSIS
#include <selinux/selinux.h>
#include <selinux/avc.h>
int avc_context_to_sid(security_context_t ctx, security_id_t *sid);
int avc_sid_to_context(security_id_t sid, security_context_t *ctx);
int avc_get_initial_sid(const char *name, security_id_t *sid);
DESCRIPTION
Security ID's (SID's) are opaque representations of security contexts, managed by the userspace AVC.
avc_context_to_sid() returns a SID for the given context in the memory referenced by sid.
avc_sid_to_context() returns a copy of the context represented by sid in the memory referenced by ctx. The user must free the copy with
freecon(3).
avc_get_initial_sid() returns a SID for the kernel initial security identifier specified by name.
RETURN VALUE
avc_context_to_sid() and avc_sid_to_context() return zero on success. On error, -1 is returned and errno is set appropriately.
ERRORS
ENOMEM An attempt to allocate memory failed.
NOTES
As of libselinux version 2.0.86, SID's are no longer reference counted. A SID will be valid from the time it is first obtained until the
next call to avc_destroy(3). The sidget(3) and sidput(3) functions, formerly used to adjust the reference count, are no-ops and are depre-
cated.
