NAME

sanlock_selinux - Security Enhanced Linux Policy for the sanlock processes  

DESCRIPTION

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

 

BOOLEANS

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

If you want to allow sanlock to read/write fuse files, you must turn on the sanlock_use_fusefs boolean.

setsebool -P sanlock_use_fusefs 1

If you want to allow confined virtual guests to interact with the sanlock, you must turn on the virt_use_sanlock boolean.

setsebool -P virt_use_sanlock 1

If you want to allow sanlock to manage nfs files, you must turn on the sanlock_use_nfs boolean.

setsebool -P sanlock_use_nfs 1

If you want to allow sanlock to manage cifs files, you must turn on the sanlock_use_samba boolean.

setsebool -P sanlock_use_samba 1

 

NSSWITCH DOMAIN

If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd serve for the sanlock_t, you must turn on the authlogin_nsswitch_use_ldap boolean.

setsebool -P authlogin_nsswitch_use_ldap 1

If you want to allow confined applications to run with kerberos for the sanlock_t, you must turn on the kerberos_enabled boolean.

setsebool -P kerberos_enabled 1

 

FILE CONTEXTS

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

The following file types are defined for sanlock:

sanlock_exec_t

- Set files with the sanlock_exec_t type, if you want to transition an executable to the sanlock_t domain.

sanlock_initrc_exec_t

- Set files with the sanlock_initrc_exec_t type, if you want to transition an executable to the sanlock_initrc_t domain.

sanlock_log_t

- Set files with the sanlock_log_t type, if you want to treat the data as sanlock log data, usually stored under the /var/log directory.

sanlock_var_run_t

- Set files with the sanlock_var_run_t type, if you want to store the sanlock files under the /run directory.

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

The following process types are defined for sanlock:

sanlock_t

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.

 

MANAGED FILES

The SELinux user type sanlock_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.


sanlock_log_t

        /var/log/sanlock.log.*


sanlock_var_run_t

        /var/run/sanlock(/.*)?


virt_var_lib_t

        /var/lib/oz(/.*)?

       /var/lib/libvirt(/.*)?

 

COMMANDS

semanage fcontext can also be used to manipulate default file context mappings.
