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 cus-
matchpathcon_init_prefix is the same as matchpathcon_init but only loads entries with regular expressions that have stems prefixed by pre-
matchpathcon_fini frees the memory allocated by a prior call to matchpathcon_init. This function can be used to free and reset the inter-
nal 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_filespec_add(3)
Returns zero on success or -1 otherwise.
