6 calamaris_selinux - Security Enhanced Linux Policy for the calamaris
7 processes
8
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
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
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
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 all daemons the ability to read/write terminals,
61 you must turn on the allow_daemons_use_tty boolean. Disabled by
62 default.
63
64 setsebool -P allow_daemons_use_tty 1
65
66
67
68 If you want to allow all domains to use other domains file descriptors,
69 you must turn on the allow_domain_fd_use boolean. Enabled by default.

85 setsebool -P allow_ptrace 1
86
87
88
89 If you want to allow system to run with NIS, you must turn on the
90 allow_ypbind boolean. Disabled by default.
91
92 setsebool -P allow_ypbind 1
93
94
95
96 If you want to allow all domains to have the kernel load modules, you
97 must turn on the domain_kernel_load_modules boolean. Disabled by
98 default.
99
100 setsebool -P domain_kernel_load_modules 1
101
102
103
104 If you want to allow all domains to execute in fips_mode, you must turn
105 on the fips_mode boolean. Enabled by default.
106
107 setsebool -P fips_mode 1
108
109
110
111 If you want to enable reading of urandom for all domains, you must turn
112 on the global_ssp boolean. Disabled by default.
113
114 setsebool -P global_ssp 1
115
116
117
118 If you want to allow confined applications to use nscd shared memory,
119 you must turn on the nscd_use_shm boolean. Enabled by default.
120
121 setsebool -P nscd_use_shm 1
122
123
124
126 The SELinux process type calamaris_t can manage files labeled with the
127 following file types. The paths listed are the default paths for these
128 file types. Note the processes UID still need to have DAC permissions.
129
130 calamaris_log_t
131
132 /var/log/calamaris(/.*)?
133
134 calamaris_www_t
135
136 /var/www/calamaris(/.*)?
137
138 initrc_tmp_t

166 SELinux requires files to have an extended attribute to define the file
167 type.
168
169 You can see the context of a file using the -Z option to ls
170
171 Policy governs the access confined processes have to these files.
172 SELinux calamaris policy is very flexible allowing users to setup their
173 calamaris processes in as secure a method as possible.
174
175 STANDARD FILE CONTEXT
176
177 SELinux defines the file context types for the calamaris, if you wanted
178 to store files with these types in a diffent paths, you need to execute
179 the semanage command to sepecify alternate labeling and then use
180 restorecon to put the labels on disk.
181
182 semanage fcontext -a -t calamaris_www_t '/srv/mycalamaris_con‐
183 tent(/.*)?'
184 restorecon -R -v /srv/mycalamaris_content
185
186 Note: SELinux often uses regular expressions to specify labels that
187 match multiple files.
188
189 The following file types are defined for calamaris:
190
191
192
193 calamaris_exec_t
194
195 - Set files with the calamaris_exec_t type, if you want to transition
196 an executable to the calamaris_t domain.
197
198
199
200 calamaris_log_t
201
202 - Set files with the calamaris_log_t type, if you want to treat the
203 data as calamaris log data, usually stored under the /var/log direc‐
204 tory.
205
206
207
208 calamaris_www_t
209
210 - Set files with the calamaris_www_t type, if you want to treat the
211 files as calamaris www data.
212
213
214
215 Note: File context can be temporarily modified with the chcon command.
216 If you want to permanently change the file context you need to use the
217 semanage fcontext command. This will modify the SELinux labeling data‐
218 base. You will need to use restorecon to apply the labels.
219
220
222 semanage fcontext can also be used to manipulate default file context
223 mappings.
224
225 semanage permissive can also be used to manipulate whether or not a
226 process type is permissive.
227
228 semanage module can also be used to enable/disable/install/remove pol‐
229 icy modules.
230
231 semanage boolean can also be used to manipulate the booleans
232
233
234 system-config-selinux is a GUI tool available to customize SELinux pol‐
235 icy settings.
