NAME

6       calamaris_selinux  -  Security  Enhanced Linux Policy for the calamaris
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the calamaris  processes  via  flexible
11       mandatory access control.
12
13       The  calamaris processes execute with the calamaris_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep calamaris_t
20
21
22

ENTRYPOINTS

24       The  calamaris_t  SELinux  type can be entered via the calamaris_exec_t
25       file type.
26
27       The default entrypoint paths for the calamaris_t domain are the follow‐
28       ing:
29
30       /etc/cron.daily/calamaris
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       calamaris  policy  is very flexible allowing users to setup their cala‐
40       maris processes in as secure a method as possible.
41
42       The following process types are defined for calamaris:
43
44       calamaris_t
45
46       Note: semanage permissive -a  calamaris_t  can  be  used  to  make  the
47       process  type  calamaris_t  permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.
50
51

BOOLEANS

53       SELinux  policy  is customizable based on least access required.  cala‐
54       maris policy is extremely flexible and has several booleans that  allow
55       you to manipulate the policy and run calamaris with the tightest access
56       possible.
57
58
59
60       If you want to allow users to resolve user passwd entries directly from
61       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
62       gin_nsswitch_use_ldap boolean. Disabled by default.
63
64       setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68       If you want to deny any process from ptracing or  debugging  any  other
69       processes,  you  must  turn  on  the  deny_ptrace  boolean.  Enabled by
70       default.
71
72       setsebool -P deny_ptrace 1
73
74
75
76       If you want to allow any process  to  mmap  any  file  on  system  with
77       attribute  file_type,  you must turn on the domain_can_mmap_files bool‐
78       ean. Enabled by default.

81
82
83
84       If you want to allow all domains write to kmsg_device, while kernel  is
85       executed  with  systemd.log_target=kmsg parameter, you must turn on the
86       domain_can_write_kmsg boolean. Disabled by default.
87
88       setsebool -P domain_can_write_kmsg 1
89
90
91
92       If you want to allow all domains to use other domains file descriptors,
93       you must turn on the domain_fd_use boolean. Enabled by default.
94
95       setsebool -P domain_fd_use 1
96
97
98
99       If  you  want to allow all domains to have the kernel load modules, you
100       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
101       default.
102
103       setsebool -P domain_kernel_load_modules 1
104
105
106
107       If you want to allow all domains to execute in fips_mode, you must turn
108       on the fips_mode boolean. Enabled by default.
109
110       setsebool -P fips_mode 1
111

121       If  you  want  to allow confined applications to run with kerberos, you
122       must turn on the kerberos_enabled boolean. Enabled by default.
123
124       setsebool -P kerberos_enabled 1
125

141

MANAGED FILES

143       The SELinux process type calamaris_t can manage files labeled with  the
144       following file types.  The paths listed are the default paths for these
145       file types.  Note the processes UID still need to have DAC permissions.
146
147       calamaris_log_t
148
149            /var/log/calamaris(/.*)?
150
151       calamaris_www_t
152
153            /var/www/calamaris(/.*)?
154
155

FILE CONTEXTS

157       SELinux requires files to have an extended attribute to define the file
158       type.
159
160       You can see the context of a file using the -Z option to ls
161
162       Policy  governs  the  access  confined  processes  have to these files.
163       SELinux calamaris policy is very flexible allowing users to setup their
164       calamaris processes in as secure a method as possible.
165
166       STANDARD FILE CONTEXT
167
168       SELinux defines the file context types for the calamaris, if you wanted
169       to store files with these types in a diffent paths, you need to execute
170       the  semanage  command  to  sepecify  alternate  labeling  and then use
171       restorecon to put the labels on disk.
172
173       semanage  fcontext   -a   -t   calamaris_www_t   '/srv/mycalamaris_con‐
174       tent(/.*)?'
175       restorecon -R -v /srv/mycalamaris_content
176
177       Note:  SELinux  often  uses  regular expressions to specify labels that
178       match multiple files.
179
180       The following file types are defined for calamaris:
181
182
183
184       calamaris_exec_t
185
186       - Set files with the calamaris_exec_t type, if you want  to  transition
187       an executable to the calamaris_t domain.
188
189
190
191       calamaris_log_t
192
193       -  Set  files  with  the calamaris_log_t type, if you want to treat the
194       data as calamaris log data, usually stored under  the  /var/log  direc‐
195       tory.
196
197
198
199       calamaris_www_t
200
201       -  Set  files  with  the calamaris_www_t type, if you want to treat the
202       files as calamaris www data.
203
204
205
206       Note: File context can be temporarily modified with the chcon  command.
207       If  you want to permanently change the file context you need to use the
208       semanage fcontext command.  This will modify the SELinux labeling data‐
209       base.  You will need to use restorecon to apply the labels.
210
211

COMMANDS

213       semanage  fcontext  can also be used to manipulate default file context
214       mappings.
215
216       semanage permissive can also be used to manipulate  whether  or  not  a
217       process type is permissive.
218
219       semanage  module can also be used to enable/disable/install/remove pol‐
220       icy modules.
221
222       semanage boolean can also be used to manipulate the booleans
223
224
225       system-config-selinux is a GUI tool available to customize SELinux pol‐
226       icy settings.
