6 rshim_selinux - Security Enhanced Linux Policy for the rshim processes
7
9 Security-Enhanced Linux secures the rshim processes via flexible manda‐
10 tory access control.
11
12 The rshim processes execute with the rshim_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep rshim_t
19
20
21
23 The rshim_t SELinux type can be entered via the rshim_exec_t file type.
24
25 The default entrypoint paths for the rshim_t domain are the following:
26
27 /usr/sbin/rshim
28
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 rshim policy is very flexible allowing users to setup their rshim pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for rshim:
40
41 rshim_t
42
43 Note: semanage permissive -a rshim_t can be used to make the process
44 type rshim_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
48
50 SELinux policy is customizable based on least access required. rshim
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run rshim with the tightest access possible.

55
56 If you want to dontaudit all daemons scheduling requests (setsched,
57 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
58 Enabled by default.
59
60 setsebool -P daemons_dontaudit_scheduling 1
61
62
63
64 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66
67 setsebool -P fips_mode 1
68
69
70
72 The SELinux process type rshim_t can manage files labeled with the fol‐
73 lowing file types. The paths listed are the default paths for these
74 file types. Note the processes UID still need to have DAC permissions.

114 SELinux requires files to have an extended attribute to define the file
115 type.
116
117 You can see the context of a file using the -Z option to ls
118
119 Policy governs the access confined processes have to these files.
120 SELinux rshim policy is very flexible allowing users to setup their
121 rshim processes in as secure a method as possible.
122
123 STANDARD FILE CONTEXT
124
125 SELinux defines the file context types for the rshim, if you wanted to
126 store files with these types in a different paths, you need to execute
127 the semanage command to specify alternate labeling and then use re‐
128 storecon to put the labels on disk.
129
130 semanage fcontext -a -t rshim_exec_t '/srv/rshim/content(/.*)?'
131 restorecon -R -v /srv/myrshim_content
132
133 Note: SELinux often uses regular expressions to specify labels that
134 match multiple files.
135
136 The following file types are defined for rshim:
137
138
139
140 rshim_exec_t
141
142 - Set files with the rshim_exec_t type, if you want to transition an
143 executable to the rshim_t domain.
144
145
146
147 rshim_unit_file_t
148
149 - Set files with the rshim_unit_file_t type, if you want to treat the
150 files as rshim unit content.
151
152
153
154 Note: File context can be temporarily modified with the chcon command.
155 If you want to permanently change the file context you need to use the
156 semanage fcontext command. This will modify the SELinux labeling data‐
157 base. You will need to use restorecon to apply the labels.
158
159
161 semanage fcontext can also be used to manipulate default file context
162 mappings.
163
164 semanage permissive can also be used to manipulate whether or not a
165 process type is permissive.
166
167 semanage module can also be used to enable/disable/install/remove pol‐
168 icy modules.
169
170 semanage boolean can also be used to manipulate the booleans
171
172
173 system-config-selinux is a GUI tool available to customize SELinux pol‐
174 icy settings.
