Security Enhanced Linux Policy for the polipo processes
Security-Enhanced Linux secures the polipo processes via flexible mandatory access control.
The polipo processes execute with the polipo_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep polipo_t
The polipo_t SELinux type can be entered via the polipo_exec_t file type.
The default entrypoint paths for the polipo_t domain are the following:
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 polipo policy is very flexible allowing users to setup their polipo processes in as secure a method as possible.
The following process types are defined for polipo:
Note: semanage permissive -a polipo_t can be used to make the process type polipo_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
SELinux policy is customizable based on least access required. polipo policy is extremely flexible and has several booleans that allow you to manipulate the policy and run polipo with the tightest access possible.
If you want to allow polipo to connect to all ports > 1023, you must turn on the polipo_connect_all_unreserved boolean. Disabled by default.
setsebool -P polipo_connect_all_unreserved 1
If you want to determine whether polipo can access cifs file systems, you must turn on the polipo_use_cifs boolean. Disabled by default.
setsebool -P polipo_use_cifs 1
If you want to determine whether Polipo can access nfs file systems, you must turn on the polipo_use_nfs boolean. Disabled by default.
setsebool -P polipo_use_nfs 1
If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.
setsebool -P daemons_dontaudit_scheduling 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 system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.
setsebool -P nis_enabled 1
The SELinux process type polipo_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.
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 lsbP
Policy governs the access confined processes have to these files. SELinux polipo policy is very flexible allowing users to setup their polipo processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the polipo, if you wanted to store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.
semanage fcontext -a -t polipo_exec_t '/srv/polipo/content(/.*)?'
restorecon -R -v /srv/mypolipo_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for polipo:
- Set files with the polipo_cache_home_t type, if you want to store polipo cache files in the users home directory.
- Set files with the polipo_cache_t type, if you want to store the files under the /var/cache directory.
- Set files with the polipo_config_home_t type, if you want to store polipo config files in the users home directory.
- Set files with the polipo_etc_t type, if you want to store polipo files in the /etc directories.
- Set files with the polipo_exec_t type, if you want to transition an executable to the polipo_t domain.
- Set files with the polipo_initrc_exec_t type, if you want to transition an executable to the polipo_initrc_t domain.
- Set files with the polipo_log_t type, if you want to treat the data as polipo log data, usually stored under the /var/log directory.
- Set files with the polipo_pid_t type, if you want to store the polipo files under the /run directory.
- Set files with the polipo_unit_file_t type, if you want to treat the files as polipo unit content.
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.
semanage 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 boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
