user_wine_selinux — Security Enhanced Linux Policy for the user_wine processes

Description

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

The user_wine processes execute with the user_wine_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 user_wine_t

Entrypoints

The user_wine_t SELinux type can be entered via the mount_ecryptfs_exec_t, user_home_t, mount_exec_t, wine_exec_t file types.

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

/usr/sbin/mount.ecryptfs, /usr/sbin/umount.ecryptfs, /usr/sbin/mount.ecryptfs_private, /usr/sbin/umount.ecryptfs_private, /home/[^/]+/.+, /bin/mount.*, /bin/umount.*, /sbin/mount.*, /sbin/umount.*, /usr/bin/mount.*, /usr/bin/umount.*, /usr/sbin/mount.*, /usr/sbin/umount.*, /usr/bin/wine.*, /opt/teamviewer(/.*)?/bin/wine.*, /opt/google/picasa(/.*)?/bin/wdi, /opt/google/picasa(/.*)?/bin/wine.*, /opt/google/picasa(/.*)?/bin/msiexec, /opt/google/picasa(/.*)?/bin/notepad, /opt/google/picasa(/.*)?/bin/progman, /opt/google/picasa(/.*)?/bin/regedit, /opt/google/picasa(/.*)?/bin/regsvr32, /opt/google/picasa(/.*)?/Picasa3/.*exe, /opt/google/picasa(/.*)?/bin/uninstaller, /opt/cxoffice/bin/wine.*, /opt/picasa/wine/bin/wine.*, /usr/bin/msiexec, /usr/bin/notepad, /usr/bin/regedit, /usr/bin/regsvr32, /usr/bin/uninstaller, /home/[^/]+/cxoffice/bin/wine.+

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 psbP

Policy governs the access confined processes have to files. SELinux user_wine policy is very flexible allowing users to setup their user_wine processes in as secure a method as possible.

The following process types are defined for user_wine:

user_wine_t

Note: semanage permissive -a user_wine_t can be used to make the process type user_wine_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. user_wine policy is extremely flexible and has several booleans that allow you to manipulate the policy and run user_wine with the tightest access possible.

If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server, you must turn on the authlogin_nsswitch_use_ldap boolean. Disabled by default.

setsebool -P authlogin_nsswitch_use_ldap 1

setsebool -P deny_ptrace 1

If you want to control the ability to mmap a low area of the address space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on the mmap_low_allowed boolean. Disabled by default.

setsebool -P mmap_low_allowed 1

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

setsebool -P nis_enabled 1

setsebool -P nscd_use_shm 1

If you want to disallow programs, such as newrole, from transitioning to administrative user domains, you must turn on the secure_mode boolean. Enabled by default.

setsebool -P secure_mode 1

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

setsebool -P selinuxuser_direct_dri_enabled 1

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

setsebool -P selinuxuser_postgresql_connect_enabled 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 selinuxuser_rw_noexattrfile boolean. Enabled by default.

setsebool -P selinuxuser_rw_noexattrfile 1

If you want to allow user music sharing, you must turn on the selinuxuser_share_music boolean. Disabled by default.

setsebool -P selinuxuser_share_music 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 selinuxuser_tcp_server boolean. Disabled by default.

setsebool -P selinuxuser_tcp_server 1

If you want to allow users to run UDP servers (bind to ports and accept connection from the same domain and outside users) disabling this may break avahi discovering services on the network and other udp related services, you must turn on the selinuxuser_udp_server boolean. Disabled by default.

setsebool -P selinuxuser_udp_server 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.
