Описание (Description)
This family of functions is deprecated. For new code, please use
selabel_open(3) with the SELABEL_CTX_FILE backend in place of
matchpathcon_init(), use selabel_close(3) in place of
matchpathcon_fini(), and use selabel_lookup(3) in place of
matchpathcon().
The remaining description below is for the legacy interface.
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 whose first pathname
component is a prefix of prefix , e.g. pass "/dev" if you only
intend to call matchpathcon() with pathnames beginning with /dev.
However, this optimization is no longer necessary due to the use
of file_contexts.bin files with precompiled regular expressions,
so use of this interface is deprecated.
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, after
transformation via realpath(3) excepting any final symbolic link
component if S_IFLNK was specified as the mode, 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) call.
Возвращаемое значение (Return value)
Returns zero on success or -1 otherwise.
