NAME
jabberd_selinux - Security Enhanced Linux Policy for the jabberd processes
DESCRIPTION
Security-Enhanced Linux secures the jabberd processes via flexible mandatory access control.
The jabberd processes execute with the jabberd_t SELinux type. You can check if you have these processes running by executing the ps com-
mand with the -Z qualifier.
For example:
ps -eZ | grep jabberd_t
ENTRYPOINTS
The jabberd_t SELinux type can be entered via the jabberd_exec_t file type.
The default entrypoint paths for the jabberd_t domain are the following:
/usr/bin/sm, /usr/bin/s2s
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 jabberd policy is very flexible allowing users to setup their jabberd
processes in as secure a method as possible.
The following process types are defined for jabberd:
jabberd_router_t, jabberd_t
Note: semanage permissive -a jabberd_t can be used to make the process type jabberd_t permissive. SELinux does not deny access to permis-
sive process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANS
SELinux policy is customizable based on least access required. jabberd policy is extremely flexible and has several booleans that allow
you to manipulate the policy and run jabberd 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
PORT TYPES
SELinux 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 jabberd policy is very flexible allowing users to setup their
jabberd processes in as secure a method as possible.
The following port types are defined for jabberd:
jabber_client_port_t
Default Defined Ports:
tcp 5222,5223
jabber_interserver_port_t
Default Defined Ports:
tcp 5269
jabber_router_port_t
Default Defined Ports:
tcp 5347
MANAGED FILES
The SELinux process type jabberd_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
jabberd_var_lib_t
/var/lib/jabberd(/.*)?
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 jabberd policy is very flexible allowing users to setup their
jabberd processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the jabberd, if you wanted to store files with these types in a diffent paths, you need to exe-
cute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.
semanage fcontext -a -t jabberd_exec_t '/srv/jabberd/content(/.*)?'
restorecon -R -v /srv/myjabberd_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for jabberd:
jabberd_exec_t
- Set files with the jabberd_exec_t type, if you want to transition an executable to the jabberd_t domain.
Paths:
/usr/bin/sm, /usr/bin/s2s
jabberd_initrc_exec_t
- Set files with the jabberd_initrc_exec_t type, if you want to transition an executable to the jabberd_initrc_t domain.
jabberd_router_exec_t
- Set files with the jabberd_router_exec_t type, if you want to transition an executable to the jabberd_router_t domain.
Paths:
/usr/bin/c2s, /usr/bin/router
jabberd_var_lib_t
- Set files with the jabberd_var_lib_t type, if you want to store the jabberd files under the /var/lib 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.
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 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.
