matchpathcon(3) SELinux API documentation matchpathcon(3)
matchpathcon, matchpathcon_index - get the default SELinux security context for the specified path from the file contexts configuration
int matchpathcon_init(const char *path);
int matchpathcon_init_prefix(const char *path, const char *subset);
int matchpathcon(const char *path, mode_t mode, security_context_t *con);
int matchpathcon_index(const char *name, mode_t mode, security_context_t *con);
matchpathcon_init() loads the file contexts configuration specified by path into memory for use by subsequent matchpathcon() calls. If
path is NULL, then the active file contexts configuration is loaded by default, i.e. the path returned by selinux_file_context_path(3).
Unless the MATCHPATHCON_BASEONLY flag has been set via set_matchpathcon_flags(3), files with the same path prefix but a .homedirs and
.local suffix are also looked up and loaded if present. These files provide dynamically generated entries for user home directories and
for local customizations.
matchpathcon_init_prefix() is the same as matchpathcon_init() but only loads entries with regular expressions that have stems prefixed by
matchpathcon_fini() frees the memory allocated by a prior call to matchpathcon_init.() This function can be used to free and reset the
internal state between multiple matchpathcon_init() calls, or to free memory when finished using matchpathcon().
matchpathcon() matches the specified pathname and mode against the file contexts configuration and sets the security context con to refer
to the resulting context. The caller must free the returned security context con using freecon(3) when finished using it. mode can be 0 to
disable mode matching, but should be provided whenever possible, as it may affect the matching. Only the file format bits (i.e. the file
type) of the mode are used. If matchpathcon_init() has not already been called, then this function will call it upon its first invocation
with a NULL path, defaulting to the active file contexts configuration.
matchpathcon_index() is the same as matchpathcon() but returns a specification index that can later be used in a matchpathcon_file-
Returns zero on success or -1 otherwise.
