kdump_selinux(8) kdump SELinux Policy documentation kdump_selinux(8)NAMEkdump_selinux - Security Enhanced Linux Policy for the kdump processes
DESCRIPTION
Security-Enhanced Linux secures the kdump processes via flexible manda‐
tory access control.
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the
kdumpgui_t, you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
kdumpgui_t, you must turn on the allow_kerberos boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the kdumpgui_t, you must
turn on the allow_ypbind boolean.
setsebool -P allow_ypbind 1
FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file
type.
You can see the context of a file using the -Z option to ls
Policy governs the access confined processes have to these files.
SELinux kdump policy is very flexible allowing users to setup their
kdump processes in as secure a method as possible.
The following file types are defined for kdump:
kdump_etc_t
- Set files with the kdump_etc_t type, if you want to store kdump files
in the /etc directories.
kdump_exec_t
- Set files with the kdump_exec_t type, if you want to transition an
executable to the kdump_t domain.
Paths:
/usr/sbin/kdump, /usr/sbin/kexec, /sbin/kdump, /sbin/kexec
kdump_initrc_exec_t
- Set files with the kdump_initrc_exec_t type, if you want to transi‐
tion an executable to the kdump_initrc_t domain.
kdump_unit_file_t
- Set files with the kdump_unit_file_t type, if you want to treat the
files as kdump unit content.
kdumpctl_exec_t
- Set files with the kdumpctl_exec_t type, if you want to transition an
executable to the kdumpctl_t domain.
kdumpctl_tmp_t
- Set files with the kdumpctl_tmp_t type, if you want to store kdumpctl
temporary files in the /tmp directories.
kdumpctl_unit_file_t
- Set files with the kdumpctl_unit_file_t type, if you want to treat
the files as kdumpctl unit content.
kdumpgui_exec_t
- Set files with the kdumpgui_exec_t type, if you want to transition an
executable to the kdumpgui_t domain.
kdumpgui_tmp_t
- Set files with the kdumpgui_tmp_t type, if you want to store kdumpgui
temporary files in the /tmp directories.
Note: File context can be temporarily modified with the chcon command.
If you want to permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. You will need to use restorecon to apply the labels.
PROCESS TYPES
SELinux defines process types (domains) for each process running on the
system
You can see the context of a process using the -Z option to ps
Policy governs the access confined processes have to files. SELinux
kdump policy is very flexible allowing users to setup their kdump pro‐
cesses in as secure a method as possible.
The following process types are defined for kdump:
kdumpgui_t, kdumpctl_t, kdump_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process
type permissive. Permissive process types are not denied access by
SELinux. AVC messages will still be generated.
COMMANDS
semanage fcontext can also be used to manipulate default file context
mappings.
semanage permissive can also be used to manipulate whether or not a
process type is permissive.
semanage module can also be used to enable/disable/install/remove pol‐
icy modules.
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
