NAME

6       ccs_selinux - Security Enhanced Linux Policy for the ccs processes
7

DESCRIPTION

9       Security-Enhanced  Linux  secures the ccs processes via flexible manda‐
10       tory access control.
11
12       The ccs processes execute with the ccs_t SELinux type. You can check if
13       you  have  these processes running by executing the ps command with the
14       -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep ccs_t
19
20
21

ENTRYPOINTS

23       The ccs_t SELinux type can be entered via the ccs_exec_t file type.
24
25       The default entrypoint paths for the ccs_t domain are the following:
26
27       /sbin/ccsd, /usr/sbin/ccsd
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       ccs policy is very flexible allowing users to setup their ccs processes
37       in as secure a method as possible.
38
39       The following process types are defined for ccs:
40
41       ccs_t
42
43       Note: semanage permissive -a ccs_t can be used to make the process type
44       ccs_t permissive. SELinux does not deny access  to  permissive  process
45       types, but the AVC (SELinux denials) messages are still generated.
46
47

BOOLEANS

49       SELinux  policy  is  customizable  based on least access required.  ccs
50       policy is extremely flexible and has several booleans that allow you to
51       manipulate the policy and run ccs with the tightest access possible.
52
53
54
55       If you want to allow all domains to execute in fips_mode, you must turn
56       on the fips_mode boolean. Enabled by default.
57
58       setsebool -P fips_mode 1
59
60
61
62       If you want to allow confined applications to use nscd  shared  memory,
63       you must turn on the nscd_use_shm boolean. Disabled by default.
64
65       setsebool -P nscd_use_shm 1
66

MANAGED FILES

70       The  SELinux  process type ccs_t can manage files labeled with the fol‐
71       lowing file types.  The paths listed are the default  paths  for  these
72       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

129       SELinux requires files to have an extended attribute to define the file
130       type.
131
132       You can see the context of a file using the -Z option to ls
133
134       Policy governs the access  confined  processes  have  to  these  files.
135       SELinux  ccs  policy is very flexible allowing users to setup their ccs
136       processes in as secure a method as possible.
137
138       STANDARD FILE CONTEXT
139
140       SELinux defines the file context types for the ccs, if  you  wanted  to
141       store  files  with  these types in a diffent paths, you need to execute
142       the semanage command  to  sepecify  alternate  labeling  and  then  use
143       restorecon to put the labels on disk.
144
145       semanage fcontext -a -t ccs_var_run_t '/srv/myccs_content(/.*)?'
146       restorecon -R -v /srv/myccs_content
147
148       Note:  SELinux  often  uses  regular expressions to specify labels that
149       match multiple files.
150
151       The following file types are defined for ccs:
152
153
154
155       ccs_exec_t
156
157       - Set files with the ccs_exec_t type, if you want to transition an exe‐
158       cutable to the ccs_t domain.
159
160
161       Paths:
162            /sbin/ccsd, /usr/sbin/ccsd
163
164
165       ccs_initrc_exec_t
166
167       -  Set files with the ccs_initrc_exec_t type, if you want to transition
168       an executable to the ccs_initrc_t domain.
169
170
171
172       ccs_tmp_t
173
174       - Set files with the ccs_tmp_t type, if you want to store ccs temporary
175       files in the /tmp directories.
176
177
178
179       ccs_tmpfs_t
180
181       -  Set  files with the ccs_tmpfs_t type, if you want to store ccs files
182       on a tmpfs file system.
183
184
185
186       ccs_var_lib_t
187
188       - Set files with the ccs_var_lib_t type, if you want to store  the  ccs
189       files under the /var/lib directory.
190
191
192
193       ccs_var_log_t
194
195       -  Set files with the ccs_var_log_t type, if you want to treat the data
196       as ccs var log data, usually stored under the /var/log directory.
197
198
199
200       ccs_var_run_t
201
202       - Set files with the ccs_var_run_t type, if you want to store  the  ccs
203       files under the /run or /var/run directory.
204
205
206       Paths:
207            /var/run/cluster/((ccs)|(ccsd)).pid,                /var/run/clus‐
208            ter/((ccs)|(ccsd)).sock
209
210
211       Note: File context can be temporarily modified with the chcon  command.
212       If  you want to permanently change the file context you need to use the
213       semanage fcontext command.  This will modify the SELinux labeling data‐
214       base.  You will need to use restorecon to apply the labels.
215
216

COMMANDS

218       semanage  fcontext  can also be used to manipulate default file context
219       mappings.
220
221       semanage permissive can also be used to manipulate  whether  or  not  a
222       process type is permissive.
223
224       semanage  module can also be used to enable/disable/install/remove pol‐
225       icy modules.
226
227       semanage boolean can also be used to manipulate the booleans
228
229
230       system-config-selinux is a GUI tool available to customize SELinux pol‐
231       icy settings.
