jockey_selinux(8) SELinux Policy jockey jockey_selinux(8)NAMEjockey_selinux - Security Enhanced Linux Policy for the jockey pro‐
cesses
DESCRIPTION
Security-Enhanced Linux secures the jockey processes via flexible
mandatory access control.
The jockey processes execute with the jockey_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 jockey_t
ENTRYPOINTS
The jockey_t SELinux type can be entered via the jockey_exec_t file
type.
The default entrypoint paths for the jockey_t domain are the following:
/usr/share/jockey/jockey-backend
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
jockey policy is very flexible allowing users to setup their jockey
processes in as secure a method as possible.
The following process types are defined for jockey:
jockey_t
Note: semanage permissive -a jockey_t can be used to make the process
type jockey_t permissive. SELinux does not deny access to permissive
process types, but the AVC (SELinux denials) messages are still gener‐
ated.
BOOLEANS
SELinux policy is customizable based on least access required. jockey
policy is extremely flexible and has several booleans that allow you to
manipulate the policy and run jockey 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 jockey_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
jockey_cache_t
/var/cache/jockey(/.*)?
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 jockey policy is very flexible allowing users to setup their
jockey processes in as secure a method as possible.
EQUIVALENCE DIRECTORIES
jockey policy stores data with multiple different file context types
under the /var/log/jockey directory. If you would like to store the
data in a different directory you can use the semanage command to cre‐
ate an equivalence mapping. If you wanted to store this data under the
/srv dirctory you would execute the following command:
semanage fcontext -a -e /var/log/jockey /srv/jockey
restorecon -R -v /srv/jockey
STANDARD FILE CONTEXT
SELinux defines the file context types for the jockey, 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 jockey_cache_t '/srv/jockey/content(/.*)?'
restorecon -R -v /srv/myjockey_content
Note: SELinux often uses regular expressions to specify labels that
match multiple files.
The following file types are defined for jockey:
jockey_cache_t
- Set files with the jockey_cache_t type, if you want to store the
files under the /var/cache directory.
jockey_exec_t
- Set files with the jockey_exec_t type, if you want to transition an
executable to the jockey_t domain.
jockey_var_log_t
- Set files with the jockey_var_log_t type, if you want to treat the
data as jockey var log data, usually stored under the /var/log direc‐
tory.
Paths:
/var/log/jockey(/.*)?, /var/log/jockey.log.*
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 data‐
base. 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 pol‐
icy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
