6 stratisd_selinux - Security Enhanced Linux Policy for the stratisd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the stratisd processes via flexible
11 mandatory access control.
12
13 The stratisd processes execute with the stratisd_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 stratisd_t
20
21
22
24 The stratisd_t SELinux type can be entered via the stratisd_exec_t file
25 type.
26
27 The default entrypoint paths for the stratisd_t domain are the follow‐
28 ing:
29
30 /usr/libexec/stratisd
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 stratisd policy is very flexible allowing users to setup their stratisd
40 processes in as secure a method as possible.
41
42 The following process types are defined for stratisd:
43
44 stratisd_t
45
46 Note: semanage permissive -a stratisd_t can be used to make the process
47 type stratisd_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required.
54 stratisd policy is extremely flexible and has several booleans that al‐
55 low you to manipulate the policy and run stratisd with the tightest ac‐
56 cess possible.
57
58
59
60 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63
64 setsebool -P daemons_dontaudit_scheduling 1
65
66
67
68 If you want to deny user domains applications to map a memory region as
69 both executable and writable, this is dangerous and the executable
70 should be reported in bugzilla, you must turn on the deny_execmem bool‐
71 ean. Disabled by default.
72
73 setsebool -P deny_execmem 1
74
75
76
77 If you want to control the ability to mmap a low area of the address
78 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
79 the mmap_low_allowed boolean. Disabled by default.
80
81 setsebool -P mmap_low_allowed 1
82
83
84
85 If you want to disable kernel module loading, you must turn on the se‐
86 cure_mode_insmod boolean. Disabled by default.
87
88 setsebool -P secure_mode_insmod 1
89
90
91
92 If you want to allow unconfined executables to make their heap memory
93 executable. Doing this is a really bad idea. Probably indicates a
94 badly coded executable, but could indicate an attack. This executable
95 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
96 echeap boolean. Disabled by default.
97
98 setsebool -P selinuxuser_execheap 1
99
100
101
102 If you want to allow unconfined executables to make their stack exe‐
103 cutable. This should never, ever be necessary. Probably indicates a
104 badly coded executable, but could indicate an attack. This executable
105 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
106 stack boolean. Enabled by default.
107
108 setsebool -P selinuxuser_execstack 1
109
110
111
113 The SELinux process type stratisd_t can manage files labeled with the
114 following file types. The paths listed are the default paths for these
115 file types. Note the processes UID still need to have DAC permissions.
116
117 file_type
118
119 all files on the system
120
121
123 SELinux requires files to have an extended attribute to define the file
124 type.
125
126 You can see the context of a file using the -Z option to ls
127
128 Policy governs the access confined processes have to these files.
129 SELinux stratisd policy is very flexible allowing users to setup their
130 stratisd processes in as secure a method as possible.
131
132 EQUIVALENCE DIRECTORIES
133
134
135 stratisd policy stores data with multiple different file context types
136 under the /var/run/stratisd directory. If you would like to store the
137 data in a different directory you can use the semanage command to cre‐
138 ate an equivalence mapping. If you wanted to store this data under the
139 /srv directory you would execute the following command:
140
141 semanage fcontext -a -e /var/run/stratisd /srv/stratisd
142 restorecon -R -v /srv/stratisd
143
144 STANDARD FILE CONTEXT
145
146 SELinux defines the file context types for the stratisd, if you wanted
147 to store files with these types in a different paths, you need to exe‐
148 cute the semanage command to specify alternate labeling and then use
149 restorecon to put the labels on disk.
150
151 semanage fcontext -a -t stratisd_exec_t '/srv/stratisd/content(/.*)?'
152 restorecon -R -v /srv/mystratisd_content
153
154 Note: SELinux often uses regular expressions to specify labels that
155 match multiple files.
156
157 The following file types are defined for stratisd:
158
159
160
161 stratisd_data_t
162
163 - Set files with the stratisd_data_t type, if you want to treat the
164 files as stratisd content.
165
166
167 Paths:
168 /stratis(/.*)?, /dev/stratis(/.*)?
169
170
171 stratisd_exec_t
172
173 - Set files with the stratisd_exec_t type, if you want to transition an
174 executable to the stratisd_t domain.
175
176
177
178 stratisd_var_run_t
179
180 - Set files with the stratisd_var_run_t type, if you want to store the
181 stratisd files under the /run or /var/run directory.
182
183
184 Paths:
185 /var/run/stratisd.*, /var/run/stratisd(/.*)?
186
187
188 Note: File context can be temporarily modified with the chcon command.
189 If you want to permanently change the file context you need to use the
190 semanage fcontext command. This will modify the SELinux labeling data‐
191 base. You will need to use restorecon to apply the labels.
192
193
195 semanage fcontext can also be used to manipulate default file context
196 mappings.
197
198 semanage permissive can also be used to manipulate whether or not a
199 process type is permissive.
200
201 semanage module can also be used to enable/disable/install/remove pol‐
202 icy modules.
203
204 semanage boolean can also be used to manipulate the booleans
205
206
207 system-config-selinux is a GUI tool available to customize SELinux pol‐
208 icy settings.
