NAME
dirsrvadmin_selinux - Security Enhanced Linux Policy for the dirsrvadmin processes
DESCRIPTION
Security-Enhanced Linux secures the dirsrvadmin processes via flexible mandatory access control.
The dirsrvadmin processes execute with the dirsrvadmin_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 dirsrvadmin_t
ENTRYPOINTS
The dirsrvadmin_t SELinux type can be entered via the shell_exec_t, dirsrvadmin_exec_t file types.
The default entrypoint paths for the dirsrvadmin_t domain are the following:
/bin/d?ash, /bin/zsh.*, /bin/ksh.*, /usr/bin/d?ash, /usr/bin/zsh.*, /usr/bin/ksh.*, /bin/esh, /bin/mksh, /bin/sash, /bin/tcsh, /bin/yash,
/bin/bash, /bin/fish, /bin/bash2, /usr/bin/esh, /usr/bin/sash, /usr/bin/tcsh, /usr/bin/yash, /usr/bin/fish, /usr/bin/mksh, /usr/bin/bash,
/sbin/nologin, /usr/sbin/sesh, /usr/bin/bash2, /usr/sbin/smrsh, /usr/bin/scponly, /usr/sbin/nologin, /usr/libexec/sesh, /usr/sbin/scponlyc,
/usr/bin/git-shell, /usr/libexec/git-core/git-shell, /usr/sbin/stop-ds-admin, /usr/sbin/start-ds-admin, /usr/sbin/restart-ds-admin
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 dirsrvadmin policy is very flexible allowing users to setup their
dirsrvadmin processes in as secure a method as possible.
The following process types are defined for dirsrvadmin:
dirsrvadmin_unconfined_script_t, dirsrvadmin_t
Note: semanage permissive -a dirsrvadmin_t can be used to make the process type dirsrvadmin_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. dirsrvadmin policy is extremely flexible and has several booleans that
allow you to manipulate the policy and run dirsrvadmin with the tightest access possible.
If you want to allow all daemons to write corefiles to /, you must turn on the daemons_dump_core boolean. Disabled by default.
setsebool -P daemons_dump_core 1
If you want to enable cluster mode for daemons, you must turn on the daemons_enable_cluster_mode boolean. Enabled by default.
setsebool -P daemons_enable_cluster_mode 1
If you want to allow all daemons to use tcp wrappers, you must turn on the daemons_use_tcp_wrapper boolean. Disabled by default.
setsebool -P daemons_use_tcp_wrapper 1
If you want to allow all daemons the ability to read/write terminals, you must turn on the daemons_use_tty boolean. Disabled by default.
setsebool -P daemons_use_tty 1
If you want to deny any process from ptracing or debugging any other processes, you must turn on the deny_ptrace boolean. Enabled by
default.
setsebool -P deny_ptrace 1
If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.
setsebool -P domain_fd_use 1
If you want to allow all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. Disabled by
default.
setsebool -P domain_kernel_load_modules 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 enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.
setsebool -P global_ssp 1
MANAGED FILES
The SELinux process type dirsrvadmin_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.
cluster_conf_t
/etc/cluster(/.*)?
cluster_var_lib_t
/var/lib/pcsd(/.*)?
/var/lib/cluster(/.*)?
/var/lib/openais(/.*)?
/var/lib/pengine(/.*)?
/var/lib/corosync(/.*)?
/usr/lib/heartbeat(/.*)?
/var/lib/heartbeat(/.*)?
/var/lib/pacemaker(/.*)?
cluster_var_run_t
/var/run/crm(/.*)?
/var/run/cman_.*
/var/run/rsctmp(/.*)?
/var/run/aisexec.*
/var/run/heartbeat(/.*)?
/var/run/cpglockd.pid
/var/run/corosync.pid
/var/run/rgmanager.pid
/var/run/cluster/rgmanager.sk
dirsrvadmin_tmp_t
root_t
/
/initrd
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 ls
Policy governs the access confined processes have to these files. SELinux dirsrvadmin policy is very flexible allowing users to setup
their dirsrvadmin processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the dirsrvadmin, 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 dirsrvadmin_config_t '/srv/dirsrvadmin/content(/.*)?'
restorecon -R -v /srv/mydirsrvadmin_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for dirsrvadmin:
dirsrvadmin_config_t
- Set files with the dirsrvadmin_config_t type, if you want to treat the files as dirsrvadmin configuration data, usually stored under the
/etc directory.
Paths:
/etc/dirsrv/dsgw(/.*)?, /etc/dirsrv/admin-serv(/.*)?
dirsrvadmin_exec_t
- Set files with the dirsrvadmin_exec_t type, if you want to transition an executable to the dirsrvadmin_t domain.
Paths:
/usr/sbin/stop-ds-admin, /usr/sbin/start-ds-admin, /usr/sbin/restart-ds-admin
dirsrvadmin_lock_t
- Set files with the dirsrvadmin_lock_t type, if you want to treat the files as dirsrvadmin lock data, stored under the /var/lock directory
dirsrvadmin_tmp_t
- Set files with the dirsrvadmin_tmp_t type, if you want to store dirsrvadmin temporary files in the /tmp directories.
dirsrvadmin_unconfined_script_exec_t
- Set files with the dirsrvadmin_unconfined_script_exec_t type, if you want to transition an executable to the dirsrvadmin_uncon-
fined_script_t domain.
Paths:
/usr/lib/dirsrv/cgi-bin/ds_create, /usr/lib/dirsrv/cgi-bin/ds_remove
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.
COMMANDS
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.
