Execute calls on selinux

salt.modules.selinux.fcontext_add_policy(name, filetype=None, sel_type=None, sel_user=None, sel_level=None)

New in version 2019.2.0.

Adds the SELinux policy for a given filespec and other optional parameters.

Returns the result of the call to semanage.

Note that you don't have to remove an entry before setting a new one for a given filespec and filetype, as adding one with semanage automatically overwrites a previously configured SELinux context.

name

filespec of the file or directory. Regex syntax is allowed.

file_type

The SELinux filetype specification. Use one of [a, f, d, c, b, s, l, p]. See also man semanage-fcontext. Defaults to 'a' (all files).

sel_type

SELinux context type. There are many.

sel_user

SELinux user. Use semanage login -l to determine which ones are available to you.

sel_level

CLI Example:

salt '*' selinux.fcontext_add_policy my-policy

salt.modules.selinux.fcontext_apply_policy(name, recursive=False)

New in version 2017.7.0.

Applies SElinux policies to filespec using restorecon [-R] filespec. Returns dict with changes if successful, the output of the restorecon command otherwise.

name

filespec of the file or directory. Regex syntax is allowed.

recursive

Recursively apply SELinux policies.

CLI Example:

salt '*' selinux.fcontext_apply_policy my-policy

Deletes the SELinux policy for a given filespec and other optional parameters.

Returns the result of the call to semanage.

Note that you don't have to remove an entry before setting a new one for a given filespec and filetype, as adding one with semanage automatically overwrites a previously configured SELinux context.

name

sel_type

SELinux context type. There are many.

sel_user

SELinux user. Use semanage login -l to determine which ones are available to you.

sel_level

The MLS range of the SELinux context.

CLI Example:

salt '*' selinux.fcontext_delete_policy my-policy

salt.modules.selinux.fcontext_get_policy(name, filetype=None, sel_type=None, sel_user=None, sel_level=None)

New in version 2017.7.0.

Returns the current entry in the SELinux policy list as a dictionary. Returns None if no exact match was found.

Returned keys are:

• filespec (the name supplied and matched)

• filetype (the descriptive name of the filetype supplied)

• sel_user, sel_role, sel_type, sel_level (the selinux context)
