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 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 For example:
18 ps -eZ | grep stratisd_t
20
24 The stratisd_t SELinux type can be entered via the stratisd_exec_t file
25 type.
26 The default entrypoint paths for the stratisd_t domain are the follow‐
28 ing:
29 /usr/libexec/stratisd
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for stratisd:
43 stratisd_t
45 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
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 If you want to deny user domains applications to map a memory region as
61 both executable and writable, this is dangerous and the executable
62 should be reported in bugzilla, you must turn on the deny_execmem bool‐
63 ean. Enabled by default.
64 setsebool -P deny_execmem 1
66 If you want to control the ability to mmap a low area of the address
70 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
71 the mmap_low_allowed boolean. Disabled by default.
72 setsebool -P mmap_low_allowed 1
74 If you want to disable kernel module loading, you must turn on the se‐
78 cure_mode_insmod boolean. Enabled by default.
79 setsebool -P secure_mode_insmod 1
81 If you want to allow unconfined executables to make their heap memory
85 executable. Doing this is a really bad idea. Probably indicates a
86 badly coded executable, but could indicate an attack. This executable
87 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
88 echeap boolean. Disabled by default.
89 setsebool -P selinuxuser_execheap 1
91 If you want to allow unconfined executables to make their stack exe‐
95 cutable. This should never, ever be necessary. Probably indicates a
96 badly coded executable, but could indicate an attack. This executable
97 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
98 stack boolean. Enabled by default.
99 setsebool -P selinuxuser_execstack 1

105 The SELinux process type stratisd_t can manage files labeled with the
106 following file types. The paths listed are the default paths for these
107 file types. Note the processes UID still need to have DAC permissions.
108 file_type
110 all files on the system
112
115 SELinux requires files to have an extended attribute to define the file
116 type.
117 You can see the context of a file using the -Z option to ls
119 Policy governs the access confined processes have to these files.
121 SELinux stratisd policy is very flexible allowing users to setup their
122 stratisd processes in as secure a method as possible.
123 EQUIVALENCE DIRECTORIES
125 stratisd policy stores data with multiple different file context types
128 under the /var/run/stratisd directory. If you would like to store the
129 data in a different directory you can use the semanage command to cre‐
130 ate an equivalence mapping. If you wanted to store this data under the
131 /srv directory you would execute the following command:
132 semanage fcontext -a -e /var/run/stratisd /srv/stratisd
134 restorecon -R -v /srv/stratisd
135 STANDARD FILE CONTEXT
137 SELinux defines the file context types for the stratisd, if you wanted
139 to store files with these types in a diffent paths, you need to execute
140 the semanage command to specify alternate labeling and then use re‐
141 storecon to put the labels on disk.
142 semanage fcontext -a -t stratisd_data_t '/srv/mystratisd_content(/.*)?'
144 restorecon -R -v /srv/mystratisd_content
145 Note: SELinux often uses regular expressions to specify labels that
147 match multiple files.
148 The following file types are defined for stratisd:
150 stratisd_data_t
154 - Set files with the stratisd_data_t type, if you want to treat the
156 files as stratisd content.
157 Paths:
160 /stratis(/.*)?, /dev/stratis(/.*)?
161 stratisd_exec_t
164 - Set files with the stratisd_exec_t type, if you want to transition an
166 executable to the stratisd_t domain.
167 stratisd_var_run_t
171 - Set files with the stratisd_var_run_t type, if you want to store the
173 stratisd files under the /run or /var/run directory.
174 Paths:
177 /var/run/stratisd.*, /var/run/stratisd(/.*)?
178 Note: File context can be temporarily modified with the chcon command.
181 If you want to permanently change the file context you need to use the
182 semanage fcontext command. This will modify the SELinux labeling data‐
183 base. You will need to use restorecon to apply the labels.
184
187 semanage fcontext can also be used to manipulate default file context
188 mappings.
189 semanage permissive can also be used to manipulate whether or not a
191 process type is permissive.
192 semanage module can also be used to enable/disable/install/remove pol‐
194 icy modules.
195 semanage boolean can also be used to manipulate the booleans
197 system-config-selinux is a GUI tool available to customize SELinux pol‐
200 icy settings.
