findcon: SELinux file context search tool
NAME
findcon - SELinux file context search toolSYNOPSIS
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 provided, 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 areblock, 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.
