NAME

       matchpathcon - get the default SELinux security context for the specified path from the file contexts configuration

SYNOPSIS

       matchpathcon [-V] [-N] [-n] [-m type] [-f file_contexts_file] [-p prefix] [-P policy_root_path] filepath...

DESCRIPTION

       matchpathcon queries the system policy and outputs the default security context associated with the filepath.

       Note: Identical paths can have different security contexts, depending on the file type (regular file, directory, link file, char file ...).

       matchpathcon  will  also take the file type into consideration in determining the default security context if the file exists.  If the file
       does not exist, no file type matching will occur.

OPTIONS

       -m type
	      Force file type for the lookup.  Valid types are file, dir, pipe, chr_file, blk_file, lnk_file, sock_file.

       -n     Do not display path.

       -N     Do not use translations.

       -f file_context_file
	      Use alternate file_context file

       -p prefix
	      Use prefix to speed translations

       -P policy_root_path
	      Use alternate policy root path

       -V     Verify file context on disk matches defaults

NAME

       matchpathcon, matchpathcon_index - get the default SELinux security context for the specified path from the file contexts configuration

SYNOPSIS

       #include <selinux/selinux.h>

       int matchpathcon_init(const char *path);

       int matchpathcon_init_prefix(const char *path, const char *subset);

       int matchpathcon_fini(void);

       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);

DESCRIPTION

       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
       prefix.

       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-
       spec_add(3) call.

RETURN VALUE

       Returns zero on success or -1 otherwise.
