NAME

       findcon - SELinux file context search tool

SYNOPSIS

       findcon FCLIST [OPTIONS] [EXPRESSION]

DESCRIPTION

       findcon allows the user to search for files with a specified context.  Results can be filtered by object class as described below.

FCLIST

       The findcon tool operates upon a file context list source.  There are three valid file context lists.

       directory
	      If  FCLIST  is  a  name of a directory then begin the search at that directory and recurse within it.  Be sure there are no circular
	      mounts within it.

       file_contexts
	      If FCLIST is the name of a file_contexts file (e.g., /etc/selinux/strict/contexts/files/file_contexts) then open that file and  find
	      matching entries.

       database
	      If FCLIST is the name of a database as created by a previous run of indexcon or apol then open the database and execute queries into
	      it.

EXPRESSION

       The following options allow the user to specify which files to print.  A file must meet all specified criteria.	If no expression  is  pro-
       vided, all files are printed.

       -t TYPE, --type=TYPE
	      Search for files with a context containing the type TYPE.

       -u USER, --user=USER
	      Search for files with a context containing the user USER.

       -r ROLE, --role=ROLE
	      Search for files with a context containing the role ROLE.

       -m RANGE, --mls-range=RANGE
	      Search for files with a context with the MLS range of RANGE.  Note that findcon ignores the SELinux translation library, if present.
	      In addition, this flag is ignored if the FCLIST has no MLS information.

       --context=CONTEXT
	      Search for files matching this partial context.  This flag overrides -t, -u, -r, and -m.

       -p PATH, --path=PATH
	      Search for files which include PATH.

       -c CLASS, --class=CLASS
	      Search only files of object class CLASS.

OPTIONS

       The following additional options are available.

       -R, --regex
	      Search using regular expressions instead of exact string matching.  This option does not affect the --class flag.

       -h, --help
	      Print help information and exit.

       -V, --version
	      Print version information and exit.

PARTIAL CONTEXT

       The --context flag specifies a partial context, which is a a colon separated list of user, role, and type.  If the system supports MLS, the
       context	may  have a fourth field that gives the range.	If a field is not specified or is the literal asterisk, then the query will always
       match the field.

OBJECT CLASSES

       Valid object class strings are

       block, char, dir, fifo, file, link, or sock.

NOTE

       The findcon utility always operates on "raw" SELinux file contexts.  If the system has an installed translation library (i.e., libsetrans),
       those translations are ignored in favor of reading the original contexts from the filesystem (if FCFILE is a directory).

EXAMPLES

       findcon .
	      Find every context in the current directory and all of its subdirectories.

       findcon -u user_u .
	      Find every context whose user is user_u in the current directory and all subdirectories.

       findcon -u system_u -t bin_t file_contexts
	      Find entries user system_u and type bin_t within a file_contexts file, assuming that file_contexts is a file contexts file.

       findcon --context=system_u::bin_t file_contexts
	      This is equivalent to the previous example.

       findcon --context=system_u:*:bin_t:* file_contexts
	      This is also equivalent to the above example.

NAME

       selinux_file_context_verify - Compare the SELinux security context on disk to the default security context required by the policy file con-
       texts file

SYNOPSIS

       #include <selinux/selinux.h>

       int selinux_file_context_verify(const char *path, mode_t mode);

DESCRIPTION

       selinux_file_context_verify() compares the context of the specified path that is held on disk (in the extended attribute),  to  the  system
       default entry held in the file contexts series of files.

       The mode may be zero.

       Note that the two contexts are compared for "significant" differences (i.e. the user component of the contexts are ignored) as shown in the
       EXAMPLE section.

RETURN VALUE

       If the contexts significantly match, 1 (one) is returned.

       If the contexts do not match 0 (zero) is returned and errno is set to either ENOENT or EINVAL for the reasons listed in the ERRORS section,
       or if errno = 0 then the contexts did not match.

       On failure -1 is returned and errno set appropriately.

ERRORS

       ENOTSUP
	      if extended attributes are not supported by the file system.

       ENOENT if there is no entry in the file contexts series of files or path does not exist.

       EINVAL if the entry in the file contexts series of files or path are invalid, or the returned context fails validation.

       ENOMEM if attempt to allocate memory failed.

FILES

       The  following  configuration  files  (the  file contexts series of files) supporting the active policy will be used (should they exist) to
       determine the path default context:

	      contexts/files/file_contexts - This file must exist.

	      contexts/files/file_contexts.local - If exists has local customizations.

	      contexts/files/file_contexts.homedirs - If exists has users home directory customizations.

	      contexts/files/file_contexts.subs - If exists has substitutions that are then applied to the 'in memory' version of  the	file  con-
	      texts files.

EXAMPLE

       If the files context is:
	      unconfined_u:object_r:admin_home_t:s0

       and the default context defined in the file contexts file is:
	      system_u:object_r:admin_home_t:s0

       then the actual strings compared are:
	      :object_r:admin_home_t:s0 and :object_r:admin_home_t:s0

       Therefore they will match and selinux_file_context_verify() will return 1.
