6 afs_fsserver_selinux - Security Enhanced Linux Policy for the
7 afs_fsserver processes
8
10 Security-Enhanced Linux secures the afs_fsserver processes via flexible
11 mandatory access control.
12
13 The afs_fsserver processes execute with the afs_fsserver_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep afs_fsserver_t
20
21
22
24 The afs_fsserver_t SELinux type can be entered via the
25 afs_fsserver_exec_t file type.
26
27 The default entrypoint paths for the afs_fsserver_t domain are the fol‐
28 lowing:
29
30 /usr/afs/bin/salvager, /usr/afs/bin/volserver, /usr/afs/bin/dasalvager,
31 /usr/afs/bin/fileserver, /usr/afs/bin/davolserver, /usr/afs/bin/dafile‐
32 server, /usr/afs/bin/salvageserver, /usr/libexec/openafs/salvager,
33 /usr/libexec/openafs/volserver, /usr/libexec/openafs/fileserver
34
36 SELinux defines process types (domains) for each process running on the
37 system
38
39 You can see the context of a process using the -Z option to ps
40
41 Policy governs the access confined processes have to files. SELinux
42 afs_fsserver policy is very flexible allowing users to setup their
43 afs_fsserver processes in as secure a method as possible.
44
45 The following process types are defined for afs_fsserver:
46
47 afs_fsserver_t
48
49 Note: semanage permissive -a afs_fsserver_t can be used to make the
50 process type afs_fsserver_t permissive. SELinux does not deny access to
51 permissive process types, but the AVC (SELinux denials) messages are
52 still generated.
53
54
56 SELinux policy is customizable based on least access required.
57 afs_fsserver policy is extremely flexible and has several booleans that
58 allow you to manipulate the policy and run afs_fsserver with the tight‐
59 est access possible.
60
61
62
63 If you want to allow all domains to execute in fips_mode, you must turn
64 on the fips_mode boolean. Enabled by default.
65
66 setsebool -P fips_mode 1

71 The SELinux process type afs_fsserver_t can manage files labeled with
72 the following file types. The paths listed are the default paths for
73 these file types. Note the processes UID still need to have DAC per‐
74 missions.
75
76 afs_config_t
77
78 /etc/(open)?afs(/.*)?
79 /usr/afs/etc(/.*)?
80 /usr/afs/local(/.*)?
81
82 afs_files_t
83
84 /usr/afs(/.*)?
85 /vicepa
86 /vicepb
87 /vicepc
88
89 afs_logfile_t
90
91 /usr/afs/logs(/.*)?
92
93
95 SELinux requires files to have an extended attribute to define the file
96 type.
97
98 You can see the context of a file using the -Z option to ls
99
100 Policy governs the access confined processes have to these files.
101 SELinux afs_fsserver policy is very flexible allowing users to setup
102 their afs_fsserver processes in as secure a method as possible.
103
104 The following file types are defined for afs_fsserver:
105
106
107
108 afs_fsserver_exec_t
109
110 - Set files with the afs_fsserver_exec_t type, if you want to transi‐
111 tion an executable to the afs_fsserver_t domain.
112
113
114 Paths:
115 /usr/afs/bin/salvager, /usr/afs/bin/volserver, /usr/afs/bin/dasal‐
116 vager, /usr/afs/bin/fileserver, /usr/afs/bin/davolserver,
117 /usr/afs/bin/dafileserver, /usr/afs/bin/salvageserver,
118 /usr/libexec/openafs/salvager, /usr/libexec/openafs/volserver,
119 /usr/libexec/openafs/fileserver
120
121
122 Note: File context can be temporarily modified with the chcon command.
123 If you want to permanently change the file context you need to use the
124 semanage fcontext command. This will modify the SELinux labeling data‐
125 base. You will need to use restorecon to apply the labels.
126
127
129 semanage fcontext can also be used to manipulate default file context
130 mappings.
131
132 semanage permissive can also be used to manipulate whether or not a
133 process type is permissive.
134
135 semanage module can also be used to enable/disable/install/remove pol‐
136 icy modules.
137
138 semanage boolean can also be used to manipulate the booleans
139
140
141 system-config-selinux is a GUI tool available to customize SELinux pol‐
142 icy settings.
