6 sysadm_seunshare_selinux - Security Enhanced Linux Policy for the
7 sysadm_seunshare processes
8
10 Security-Enhanced Linux secures the sysadm_seunshare processes via
11 flexible mandatory access control.
12
13 The sysadm_seunshare processes execute with the sysadm_seunshare_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
17 For example:
18
19 ps -eZ | grep sysadm_seunshare_t
20
21
22
24 The sysadm_seunshare_t SELinux type can be entered via the seun‐
25 share_exec_t file type.
26
27 The default entrypoint paths for the sysadm_seunshare_t domain are the
28 following:
29
30 /usr/sbin/seunshare
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 sysadm_seunshare policy is very flexible allowing users to setup their
40 sysadm_seunshare processes in as secure a method as possible.
41
42 The following process types are defined for sysadm_seunshare:
43
44 sysadm_seunshare_t
45
46 Note: semanage permissive -a sysadm_seunshare_t can be used to make the
47 process type sysadm_seunshare_t permissive. SELinux does not deny
48 access to permissive process types, but the AVC (SELinux denials) mes‐
49 sages are still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 sysadm_seunshare policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run sysadm_seunshare with
56 the tightest access possible.
57
58
59
60 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
64 setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Disabled by default.
77
78 setsebool -P kerberos_enabled 1
79
80
81
82 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84
85 setsebool -P nis_enabled 1
86
87
88
89 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
97 The SELinux process type sysadm_seunshare_t can manage files labeled
98 with the following file types. The paths listed are the default paths
99 for these file types. Note the processes UID still need to have DAC
100 permissions.
101
102 cgroup_t
103
104 /sys/fs/cgroup
105
106 sandbox_file_t
107
108
109 sandbox_tmpfs_type
110
111 all sandbox content in tmpfs file systems
112
113
115 semanage fcontext can also be used to manipulate default file context
116 mappings.
117
118 semanage permissive can also be used to manipulate whether or not a
119 process type is permissive.
120
121 semanage module can also be used to enable/disable/install/remove pol‐
122 icy modules.
123
124 semanage boolean can also be used to manipulate the booleans
125
126
127 system-config-selinux is a GUI tool available to customize SELinux pol‐
128 icy settings.
