6 rssh_chroot_helper_selinux - Security Enhanced Linux Policy for the
7 rssh_chroot_helper processes
8
10 Security-Enhanced Linux secures the rssh_chroot_helper processes via
11 flexible mandatory access control.
12
13 The rssh_chroot_helper processes execute with the rssh_chroot_helper_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 rssh_chroot_helper_t
20
21
22
24 The rssh_chroot_helper_t SELinux type can be entered via the rssh_ch‐
25 root_helper_exec_t file type.
26
27 The default entrypoint paths for the rssh_chroot_helper_t domain are
28 the following:
29
30 /usr/libexec/rssh_chroot_helper
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 rssh_chroot_helper policy is very flexible allowing users to setup
40 their rssh_chroot_helper processes in as secure a method as possible.
41
42 The following process types are defined for rssh_chroot_helper:
43
44 rssh_chroot_helper_t
45
46 Note: semanage permissive -a rssh_chroot_helper_t can be used to make
47 the process type rssh_chroot_helper_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 rssh_chroot_helper policy is extremely flexible and has several bool‐
55 eans that allow you to manipulate the policy and run rssh_chroot_helper
56 with the tightest access possible.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
67 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69
70 setsebool -P nis_enabled 1
71
72
73
75 The SELinux process type rssh_chroot_helper_t can manage files labeled
76 with the following file types. The paths listed are the default paths
77 for these file types. Note the processes UID still need to have DAC
78 permissions.
79
80 krb5_host_rcache_t
81
82 /var/tmp/krb5_0.rcache2
83 /var/cache/krb5rcache(/.*)?
84 /var/tmp/nfs_0
85 /var/tmp/DNS_25
86 /var/tmp/host_0
87 /var/tmp/imap_0
88 /var/tmp/HTTP_23
89 /var/tmp/HTTP_48
90 /var/tmp/ldap_55
91 /var/tmp/ldap_487
92 /var/tmp/ldapmap1_0
93
94
96 SELinux requires files to have an extended attribute to define the file
97 type.
98
99 You can see the context of a file using the -Z option to ls
100
101 Policy governs the access confined processes have to these files.
102 SELinux rssh_chroot_helper policy is very flexible allowing users to
103 setup their rssh_chroot_helper processes in as secure a method as pos‐
104 sible.
105
106 STANDARD FILE CONTEXT
107
108 SELinux defines the file context types for the rssh_chroot_helper, if
109 you wanted to store files with these types in a different paths, you
110 need to execute the semanage command to specify alternate labeling and
111 then use restorecon to put the labels on disk.
112
113 semanage fcontext -a -t rssh_chroot_helper_exec_t '/srv/rssh_ch‐
114 root_helper/content(/.*)?'
115 restorecon -R -v /srv/myrssh_chroot_helper_content
116
117 Note: SELinux often uses regular expressions to specify labels that
118 match multiple files.
119
120 The following file types are defined for rssh_chroot_helper:
121
122
123
124 rssh_chroot_helper_exec_t
125
126 - Set files with the rssh_chroot_helper_exec_t type, if you want to
127 transition an executable to the rssh_chroot_helper_t domain.
128
129
130
131 Note: File context can be temporarily modified with the chcon command.
132 If you want to permanently change the file context you need to use the
133 semanage fcontext command. This will modify the SELinux labeling data‐
134 base. You will need to use restorecon to apply the labels.
135
136
138 semanage fcontext can also be used to manipulate default file context
139 mappings.
140
141 semanage permissive can also be used to manipulate whether or not a
142 process type is permissive.
143
144 semanage module can also be used to enable/disable/install/remove pol‐
145 icy modules.
146
147 semanage boolean can also be used to manipulate the booleans
148
149
150 system-config-selinux is a GUI tool available to customize SELinux pol‐
151 icy settings.
