semanage-fcontext: SELinux Policy Management file context tool

NAME

semanage-fcontext - SELinux Policy Management file context tool

SYNOPSIS

semanage fcontext [-h] [-n] [-N] [-S STORE] [ --add ( -t TYPE -f FTYPE -r RANGE -s SEUSER | -e EQUAL ) FILE_SPEC ) | --delete ( -t TYPE -f FTYPE | -e EQUAL ) FILE_SPEC ) | --deleteall | --extract | --list [-C] | --modify ( -t TYPE -f FTYPE -r RANGE -s SEUSER | -e EQUAL ) FILE_SPEC ) ]

DESCRIPTION

semanage is used to configure certain elements of SELinux policy without requiring modification to or recompilation from policy sources. semanage fcontext is used to manage the default file system labeling on an SELinux system. This command maps file paths using regular expressions to SELinux labels.

OPTIONS

-h, --help

show this help message and exit

-n, --noheading

Do not print heading when listing the specified object type

-N, --noreload

Do not reload policy after commit

-C, --locallist

List local customizations

-S STORE, --store STORE

Select an alternate SELinux Policy Store to manage

-a, --add

Add a record of the specified object type

-d, --delete

Delete a record of the specified object type

-m, --modify

Modify a record of the specified object type

-l, --list

List records of the specified object type

-E, --extract

Extract customizable commands, for use within a transaction

-D, --deleteall

Remove all local customizations

-e EQUAL, --equal EQUAL

Substitute target path with sourcepath when generating default label. This is used with fcontext. Requires source and target path arguments. The context labeling for the target subtree is made equivalent to that defined for the source.

-f [{a,f,d,c,b,s,l,p}], --ftype [{a,f,d,c,b,s,l,p}]

File Type. This is used with fcontext. Requires a file type as shown in the mode field by ls, e.g. use 'd' to match only directories or 'f' to match only regular files. The following file type options can be passed: f (regular file),d (directory),c (character device), b (block device),s (socket),l (symbolic link),p (named pipe). If you do not specify a file type, the file type will default to "all files".

-s SEUSER, --seuser SEUSER

SELinux user name

-t TYPE, --type TYPE

SELinux Type for the object

-r RANGE, --range RANGE

MLS/MCS Security Range (MLS/MCS Systems only) SELinux Range for SELinux login mapping defaults to the SELinux user record range. SELinux Range for SELinux user defaults to s0.

EXAMPLE

remember to run restorecon after you set the file context
Add file-context for everything under /web
# semanage fcontext -a -t httpd_sys_content_t "/web(/.*)?"
# restorecon -R -v /web

Substitute /home1 with /home when setting file context
# semanage fcontext -a -e /home /home1
# restorecon -R -v /home1

For home directories under top level directory, for example /disk6/home,
execute the following commands.
# semanage fcontext -a -t home_root_t "/disk6"
# semanage fcontext -a -e /home /disk6/home
# restorecon -R -v /disk6
