NAME¶

selabel_lookup - obtain SELinux security context from a string label.

SYNOPSIS¶

#include <selinux/selinux.h> #include <selinux/label.h> int selabel_lookup(struct selabel_handle *hnd,
security_context_t *context, const char *key, int type);
int selabel_lookup_raw(struct selabel_handle *hnd,
security_context_t *context, const char *key, int type);

DESCRIPTION¶

selabel_lookup performs a lookup operation on the handle hnd, returning the result in the memory pointed to by context, which must be freed by the caller using freecon(3). The key and type parameters are the inputs to the lookup operation and are interpreted according to the specific backend that handle is open on. selabel_lookup_raw behaves identically to selabel_lookup but does not perform context translation.

RETURN VALUE¶

On success, zero is returned. On error, -1 is returned and errno is set appropriately.

ERRORS¶

ENOENT

No context corresponding to the input key and type was found.

EINVAL

The key and/or type inputs are invalid, or the context being returned failed validation.

ENOMEM

An attempt to allocate memory failed.
