NAMEboinc_selinux − Security Enhanced Linux Policy for the boinc processes

DESCRIPTIONSecurity-Enhanced Linux secures the boinc processes via flexible mandatory access control. The boinc processes execute with the boinc_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 boinc_t

ENTRYPOINTSThe boinc_t SELinux type can be entered via the boinc_exec_t file type. The default entrypoint paths for the boinc_t domain are the following: /usr/bin/boinc, /usr/bin/boinc_client

PROCESS TYPESSELinux 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 boinc policy is very flexible allowing users to setup their boinc processes in as secure a method as possible. The following process types are defined for boinc: boinc_t, boinc_project_tNote: semanage permissive -a boinc_t can be used to make the process type boinc_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

BOOLEANSSELinux policy is customizable based on least access required. boinc policy is extremely flexible and has several booleans that allow you to manipulate the policy and run boinc with the tightest access possible. If you want to determine whether boinc can execmem/execstack, you must turn on the boinc_execmem boolean. Enabled by default. setsebool -P boinc_execmem 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

PORT TYPESSELinux defines port types to represent TCP and UDP ports. You can see the types associated with a port by using the following command: semanage port -l Policy governs the access confined processes have to these ports. SELinux boinc policy is very flexible allowing users to setup their boinc processes in as secure a method as possible. The following port types are defined for boinc: boinc_client_port_t    Default Defined Ports: tcp 1043 udp 1034 boinc_port_t    Default Defined Ports: tcp 31416

MANAGED FILESThe SELinux process type boinc_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.

FILE CONTEXTSSELinux 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 ls Policy governs the access confined processes have to these files. SELinux boinc policy is very flexible allowing users to setup their boinc processes in as secure a method as possible. EQUIVALENCE DIRECTORIES boinc policy stores data with multiple different file context types under the /var/lib/boinc directory. If you would like to store the data in a different directory you can use the semanage command to create an equivalence mapping. If you wanted to store this data under the /srv directory you would execute the following command: semanage fcontext -a -e /var/lib/boinc /srv/boinc
restorecon -R -v /srv/boinc
STANDARD FILE CONTEXT SELinux defines the file context types for the boinc, if you wanted to store files with these types in a diffent paths, you need to execute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk. semanage fcontext -a -t boinc_project_var_lib_t '/srv/myboinc_content(/.*)?'
restorecon -R -v /srv/myboinc_content Note: SELinux often uses regular expressions to specify labels that match multiple files. The following file types are defined for boinc:
boinc_exec_t- Set files with the boinc_exec_t type, if you want to transition an executable to the boinc_t domain.
Paths:  /usr/bin/boinc, /usr/bin/boinc_client boinc_initrc_exec_t- Set files with the boinc_initrc_exec_t type, if you want to transition an executable to the boinc_initrc_t domain. boinc_log_t- Set files with the boinc_log_t type, if you want to treat the data as boinc log data, usually stored under the /var/log directory.
Paths:  /var/log/boinc.log.*, /var/log/boincerr.log.* boinc_project_tmp_t- Set files with the boinc_project_tmp_t type, if you want to store boinc project temporary files in the /tmp directories. boinc_project_var_lib_t- Set files with the boinc_project_var_lib_t type, if you want to store the boinc project files under the /var/lib directory.
Paths:  /var/lib/boinc/slots(/.*)?, /var/lib/boinc/projects(/.*)? boinc_tmp_t- Set files with the boinc_tmp_t type, if you want to store boinc temporary files in the /tmp directories. boinc_tmpfs_t- Set files with the boinc_tmpfs_t type, if you want to store boinc files on a tmpfs file system. boinc_unit_file_t- Set files with the boinc_unit_file_t type, if you want to treat the files as boinc unit content. boinc_var_lib_t- Set files with the boinc_var_lib_t type, if you want to store the boinc files under the /var/lib directory.
Paths:  /var/lib/boinc(/.*)?, /var/lib/boinc-client(/.*)?, /etc/boinc-client/global_prefs_override.xml 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.

COMMANDSsemanage fcontext can also be used to manipulate default file context mappings. semanage permissive can also be used to manipulate whether or not a process type is permissive. semanage module can also be used to enable/disable/install/remove policy modules. semanage port can also be used to manipulate the port definitions semanage boolean can also be used to manipulate the booleans system-config-selinux is a GUI tool available to customize SELinux policy settings.
