NAMEcvs_selinux − Security Enhanced Linux Policy for the cvs processes
DESCRIPTIONSecurity-Enhanced Linux secures the cvs processes via flexible mandatory access control. The cvs processes execute with the cvs_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 cvs_t
ENTRYPOINTSThe cvs_t SELinux type can be entered via the cvs_exec_t file type. The default entrypoint paths for the cvs_t domain are the following: /usr/bin/cvs
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 cvs policy is very flexible allowing users to setup their cvs processes in as secure a method as possible. The following process types are defined for cvs: cvs_t, cvs_script_tNote: semanage permissive -a cvs_t can be used to make the process type cvs_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. cvs policy is extremely flexible and has several booleans that allow you to manipulate the policy and run cvs with the tightest access possible. If you want to determine whether cvs can read shadow password files, you must turn on the cvs_read_shadow boolean. Disabled by default. setsebool -P cvs_read_shadow 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 cvs policy is very flexible allowing users to setup their cvs processes in as secure a method as possible. The following port types are defined for cvs: cvs_port_t
Default Defined Ports: tcp 2401 udp 2401
MANAGED FILESThe SELinux process type cvs_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 cvs policy is very flexible allowing users to setup their cvs processes in as secure a method as possible. STANDARD FILE CONTEXT SELinux defines the file context types for the cvs, 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 cvs_ra_content_t '/srv/mycvs_content(/.*)?'
restorecon -R -v /srv/mycvs_content Note: SELinux often uses regular expressions to specify labels that match multiple files. The following file types are defined for cvs: cvs_content_t- Set files with the cvs_content_t type, if you want to treat the files as cvs content. cvs_data_t- Set files with the cvs_data_t type, if you want to treat the files as cvs content.
Paths: /opt/cvs(/.*)?, /var/cvs(/.*)? cvs_exec_t- Set files with the cvs_exec_t type, if you want to transition an executable to the cvs_t domain. cvs_home_t- Set files with the cvs_home_t type, if you want to store cvs files in the users home directory.
Paths: /root/.cvsignore, /home/[^/]+/.cvsignore cvs_htaccess_t- Set files with the cvs_htaccess_t type, if you want to treat the file as a cvs access file. cvs_initrc_exec_t- Set files with the cvs_initrc_exec_t type, if you want to transition an executable to the cvs_initrc_t domain. cvs_keytab_t- Set files with the cvs_keytab_t type, if you want to treat the files as kerberos keytab files. cvs_ra_content_t- Set files with the cvs_ra_content_t type, if you want to treat the files as cvs read/append content. cvs_rw_content_t- Set files with the cvs_rw_content_t type, if you want to treat the files as cvs read/write content. cvs_script_exec_t- Set files with the cvs_script_exec_t type, if you want to transition an executable to the cvs_script_t domain.
Paths: /var/www/cgi-bin/cvsweb.cgi, /usr/share/cvsweb/cvsweb.cgi cvs_tmp_t- Set files with the cvs_tmp_t type, if you want to store cvs temporary files in the /tmp directories. cvs_var_run_t- Set files with the cvs_var_run_t type, if you want to store the cvs files under the /run or /var/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.
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.
