NAMEkdump_selinux - Security Enhanced Linux Policy for the kdump processes
SELinux Linux secures kdump (Kernel crash dumping mechanism) processes via flexible mandatory access control.
FILE CONTEXTSSELinux 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 lsP 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:
- Set files with the kdump_etc_t type, if you want to store kdump files in the /etc directories.
- Set files with the kdump_exec_t type, if you want to transition an executable to the kdump_t domain.
- Set files with the kdump_initrc_exec_t type, if you want to transition an executable to the kdump_initrc_t domain.
- Set files with the kdumpgui_exec_t type, if you want to transition an executable to the kdumpgui_t domain.
- 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 permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
PROCESS TYPESSELinux defines process types (domains) for each process running on the system
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux kdump policy is very flexible allowing users to setup their kdump processes in as secure a method as possible.
The following process types are defined for kdump:
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.
COMMANDSsemanage 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 policy modules.
system-config-selinux is a GUI tool available to customize SELinux policy settings.
