NAME

       set_matchpathcon_flags,	set_matchpathcon_invalidcon,  set_matchpathcon_printf  -  set  flags  controlling the operation of matchpathcon or
       matchpathcon_index and configure the behaviour of validity checking and error displaying.

SYNOPSIS

       #include <selinux/selinux.h>

       void set_matchpathcon_flags(unsigned int flags);

       void set_matchpathcon_invalidcon(int (*f)(const char *path, unsigned lineno, char * context));

       void set_matchpathcon_printf(void (*f)(const char *fmt, ...));

DESCRIPTION

       set_matchpathcon_flags sets the flags controlling the operation of matchpathcon_init and subsequently matchpathcon_index  or  matchpathcon.
       If the MATCHPATHCON_BASEONLY flag is set, then only the base file contexts configuration file will be processed, not any dynamically gener-
       ated entries or local customizations.

       set_matchpathcon_invalidcon sets the function used by matchpathcon_init when checking the validity of a context in the file  contexts  con-
       figuration.   If  not set, then this defaults to a test based on security_check_context(3), which checks validity against the active policy
       on a SELinux system.  This can be set to instead perform checking based on a binary policy file, e.g. using sepol_check_context(3),  as	is
       done by setfiles -c.  The function is also responsible for reporting any such error, and may include the path and lineno in such error mes-
       sages.

       set_matchpathcon_printf sets the function used by matchpathcon_init when displaying errors about the file contexts configuration.   If  not
       set, then this defaults to fprintf(stderr, fmt, ...).  This can be set to redirect error reporting to a different destination.

RETURN VALUE

       Returns zero on success or -1 otherwise.

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.
