NAME¶

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 wine_exec_t, user_home_t file types.

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

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

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 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

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

setsebool -P kerberos_enabled 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

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 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 support NFS home directories, you must turn on the use_nfs_home_dirs boolean. Enabled 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 determine whether attempts by wine to mmap low regions should be silently blocked, you must turn on the wine_mmap_zero_ignore boolean. Disabled by default.

setsebool -P wine_mmap_zero_ignore 1
