6 cockpit_session_selinux - Security Enhanced Linux Policy for the cock‐
7 pit_session processes
8
10 Security-Enhanced Linux secures the cockpit_session processes via flex‐
11 ible mandatory access control.
12 The cockpit_session processes execute with the cockpit_session_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep cockpit_session_t
20
24 The cockpit_session_t SELinux type can be entered via the cockpit_ses‐
25 sion_exec_t file type.
26 The default entrypoint paths for the cockpit_session_t domain are the
28 following:
29 /usr/libexec/cockpit-ssh, /usr/libexec/cockpit-session
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 cockpit_session policy is very flexible allowing users to setup their
40 cockpit_session processes in as secure a method as possible.
41 The following process types are defined for cockpit_session:
43 cockpit_session_t
45 Note: semanage permissive -a cockpit_session_t can be used to make the
47 process type cockpit_session_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. cock‐
54 pit_session policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run cockpit_session with the
56 tightest access possible.
57 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 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to allow users to login using a radius server, you must
69 turn on the authlogin_radius boolean. Disabled by default.
70 setsebool -P authlogin_radius 1
72 If you want to allow users to login using a yubikey OTP server or chal‐
76 lenge response mode, you must turn on the authlogin_yubikey boolean.
77 Disabled by default.
78 setsebool -P authlogin_yubikey 1
80 If you want to deny any process from ptracing or debugging any other
84 processes, you must turn on the deny_ptrace boolean. Enabled by
85 default.
86 setsebool -P deny_ptrace 1
88 If you want to allow any process to mmap any file on system with
92 attribute file_type, you must turn on the domain_can_mmap_files bool‐
93 ean. Enabled by default.
94 setsebool -P domain_can_mmap_files 1
96 If you want to allow all domains write to kmsg_device, while kernel is
100 executed with systemd.log_target=kmsg parameter, you must turn on the
101 domain_can_write_kmsg boolean. Disabled by default.
102 setsebool -P domain_can_write_kmsg 1
104 If you want to allow all domains to use other domains file descriptors,
108 you must turn on the domain_fd_use boolean. Enabled by default.
109 setsebool -P domain_fd_use 1
111 If you want to allow all domains to have the kernel load modules, you
115 must turn on the domain_kernel_load_modules boolean. Disabled by
116 default.
117 setsebool -P domain_kernel_load_modules 1
119 If you want to allow all domains to execute in fips_mode, you must turn
123 on the fips_mode boolean. Enabled by default.
124 setsebool -P fips_mode 1
126 If you want to enable reading of urandom for all domains, you must turn
130 on the global_ssp boolean. Disabled by default.
131 setsebool -P global_ssp 1
133 If you want to allow confined applications to run with kerberos, you
137 must turn on the kerberos_enabled boolean. Enabled by default.
138 setsebool -P kerberos_enabled 1
140 If you want to allow system to run with NIS, you must turn on the
144 nis_enabled boolean. Disabled by default.
145 setsebool -P nis_enabled 1
147 If you want to allow confined applications to use nscd shared memory,
151 you must turn on the nscd_use_shm boolean. Disabled by default.
152 setsebool -P nscd_use_shm 1
154 If you want to enable polyinstantiated directory support, you must turn
158 on the polyinstantiation_enabled boolean. Disabled by default.
159 setsebool -P polyinstantiation_enabled 1

165 The SELinux process type cockpit_session_t can manage files labeled
166 with the following file types. The paths listed are the default paths
167 for these file types. Note the processes UID still need to have DAC
168 permissions.

285 SELinux requires files to have an extended attribute to define the file
286 type.
287 You can see the context of a file using the -Z option to ls
289 Policy governs the access confined processes have to these files.
291 SELinux cockpit_session policy is very flexible allowing users to setup
292 their cockpit_session processes in as secure a method as possible.
293 The following file types are defined for cockpit_session:
295 cockpit_session_exec_t
299 - Set files with the cockpit_session_exec_t type, if you want to tran‐
301 sition an executable to the cockpit_session_t domain.
302 Paths:
305 /usr/libexec/cockpit-ssh, /usr/libexec/cockpit-session
306 Note: File context can be temporarily modified with the chcon command.
309 If you want to permanently change the file context you need to use the
310 semanage fcontext command. This will modify the SELinux labeling data‐
311 base. You will need to use restorecon to apply the labels.
312
315 semanage fcontext can also be used to manipulate default file context
316 mappings.
317 semanage permissive can also be used to manipulate whether or not a
319 process type is permissive.
320 semanage module can also be used to enable/disable/install/remove pol‐
322 icy modules.
323 semanage boolean can also be used to manipulate the booleans
325 system-config-selinux is a GUI tool available to customize SELinux pol‐
328 icy settings.
