NAME¶

staff_mono_selinux - Security Enhanced Linux Policy for the staff_mono processes

DESCRIPTION¶

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

The staff_mono processes execute with the staff_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 staff_mono_t

ENTRYPOINTS¶

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

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

/home/[^/]*/.+, /home/staff/.+, /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.*

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

The following process types are defined for staff_mono:

staff_mono_t

Note: semanage permissive -a staff_mono_t can be used to make the process type staff_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. staff_mono policy is extremely flexible and has several booleans that allow you to manipulate the policy and run staff_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

If you want to allow all domains to use other domains file descriptors, you must turn on the allow_domain_fd_use boolean. Enabled by default.

setsebool -P allow_domain_fd_use 1

If you want to allow all unconfined executables to use libraries requiring text relocation that are not labeled textrel_shlib_t), you must turn on the allow_execmod boolean. Enabled by default.

setsebool -P allow_execmod 1

If you want to allow confined applications to run with kerberos, you must turn on the allow_kerberos boolean. Enabled by default.

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 allow users to connect to PostgreSQL, you must turn on the allow_user_postgresql_connect boolean. Disabled by default.

setsebool -P allow_user_postgresql_connect 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 regular users direct mouse access, you must turn on the user_direct_mouse boolean. Disabled by default.

setsebool -P user_direct_mouse 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 user processes to change their priority, you must turn on the user_setrlimit boolean. Enabled by default.

setsebool -P user_setrlimit 1

If you want to allow users to run TCP servers (bind to ports and accept connection from the same domain and outside users) disabling this forces FTP passive mode and may change other protocols, you must turn on the user_tcp_server boolean. Disabled by default.

setsebool -P user_tcp_server 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 support X userspace object manager, you must turn on the xserver_object_manager boolean. Disabled by default.

setsebool -P xserver_object_manager 1
