NAME¶

xguest_mono_selinux - Security Enhanced Linux Policy for the xguest_mono processes

DESCRIPTION¶

Security-Enhanced Linux secures the xguest_mono processes via flexible mandatory access control.

The xguest_mono processes execute with the xguest_mono_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.

For example:

ps -eZ | grep xguest_mono_t

ENTRYPOINTS¶

The xguest_mono_t SELinux type can be entered via the mono_exec_t, xsession_exec_t, user_home_t file types.

The default entrypoint paths for the xguest_mono_t domain are the following:

/usr/bin/mono.*, /etc/kde3?/kdm/Xreset, /etc/kde3?/kdm/Xstartup, /etc/kde3?/kdm/Xsession, /etc/X11/[wx]dm/Xreset.*, /etc/X11/[wxg]dm/Xsession, /etc/X11/Xsession[^/]*, /etc/X11/wdm/Xsetup.*, /etc/X11/wdm/Xstartup.*, /home/[^/]*/.+, /home/staff/.+

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 xguest_mono policy is very flexible allowing users to setup their xguest_mono processes in as secure a method as possible.

The following process types are defined for xguest_mono:

xguest_mono_t

Note: semanage permissive -a xguest_mono_t can be used to make the process type xguest_mono_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

BOOLEANS¶

SELinux policy is customizable based on least access required. xguest_mono policy is extremely flexible and has several booleans that allow you to manipulate the policy and run xguest_mono with the tightest access possible.

If you want to allow direct login to the console device. Required for System 390, you must turn on the allow_console_login boolean. Enabled by default.

setsebool -P allow_console_login 1

setsebool -P allow_domain_fd_use 1

setsebool -P allow_kerberos 1

If you want to allow sysadm to debug or ptrace all processes, you must turn on the allow_ptrace boolean. Disabled by default.

setsebool -P allow_ptrace 1

If you want to allows clients to write to the X server shared memory segments, you must turn on the allow_write_xshm boolean. Disabled by default.

setsebool -P allow_write_xshm 1

If you want to allow system to run with NIS, you must turn on the allow_ypbind boolean. Disabled by default.

setsebool -P allow_ypbind 1

If you want to allow all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. Disabled by default.

setsebool -P domain_kernel_load_modules 1

If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.

setsebool -P fips_mode 1

If you want to enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.

setsebool -P global_ssp 1

If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default.

setsebool -P nscd_use_shm 1

If you want to enabling secure mode disallows programs, such as newrole, from transitioning to administrative user domains, you must turn on the secure_mode boolean. Disabled by default.

setsebool -P secure_mode 1

If you want to allow ssh logins as sysadm_r:sysadm_t, you must turn on the ssh_sysadm_login boolean. Disabled by default.

setsebool -P ssh_sysadm_login 1

If you want to support NFS home directories, you must turn on the use_nfs_home_dirs boolean. Disabled by default.

setsebool -P use_nfs_home_dirs 1

If you want to support SAMBA home directories, you must turn on the use_samba_home_dirs boolean. Disabled by default.

setsebool -P use_samba_home_dirs 1

If you want to allow regular users direct dri device access, you must turn on the user_direct_dri boolean. Enabled by default.

setsebool -P user_direct_dri 1

If you want to allow user to r/w files on filesystems that do not have extended attributes (FAT, CDROM, FLOPPY), you must turn on the user_rw_noexattrfile boolean. Enabled by default.

setsebool -P user_rw_noexattrfile 1

If you want to allow xdm logins as sysadm, you must turn on the xdm_sysadm_login boolean. Disabled by default.

setsebool -P xdm_sysadm_login 1

If you want to allow xguest to configure Network Manager and connect to apache ports, you must turn on the xguest_connect_network boolean. Enabled by default.

setsebool -P xguest_connect_network 1

If you want to support X userspace object manager, you must turn on the xserver_object_manager boolean. Disabled by default.

setsebool -P xserver_object_manager 1
