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 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 For example:
18 ps -eZ | grep afs_fsserver_t
20
24 The afs_fsserver_t SELinux type can be entered via the
25 afs_fsserver_exec_t file type.
26 The default entrypoint paths for the afs_fsserver_t domain are the fol‐
28 lowing:
29 /usr/afs/bin/salvager, /usr/afs/bin/volserver, /usr/afs/bin/fileserver,
31 /usr/afs/bin/dasalvager, /usr/afs/bin/davolserver, /usr/afs/bin/dafile‐
32 server, /usr/afs/bin/salvageserver
33
35 SELinux defines process types (domains) for each process running on the
36 system
37 You can see the context of a process using the -Z option to ps
39 Policy governs the access confined processes have to files. SELinux
41 afs_fsserver policy is very flexible allowing users to setup their
42 afs_fsserver processes in as secure a method as possible.
43 The following process types are defined for afs_fsserver:
45 afs_fsserver_t
47 Note: semanage permissive -a afs_fsserver_t can be used to make the
49 process type afs_fsserver_t permissive. SELinux does not deny access to
50 permissive process types, but the AVC (SELinux denials) messages are
51 still generated.
52
55 SELinux policy is customizable based on least access required.
56 afs_fsserver policy is extremely flexible and has several booleans that
57 allow you to manipulate the policy and run afs_fsserver with the tight‐
58 est access possible.
59 If you want to allow all domains to use other domains file descriptors,
63 you must turn on the allow_domain_fd_use boolean. Enabled by default.
64 setsebool -P allow_domain_fd_use 1
66 If you want to allow sysadm to debug or ptrace all processes, you must
70 turn on the allow_ptrace boolean. Disabled by default.
71 setsebool -P allow_ptrace 1
73 If you want to allow all domains to have the kernel load modules, you
77 must turn on the domain_kernel_load_modules boolean. Disabled by
78 default.
79 setsebool -P domain_kernel_load_modules 1
81 If you want to allow all domains to execute in fips_mode, you must turn
85 on the fips_mode boolean. Enabled by default.
86 setsebool -P fips_mode 1
88 If you want to enable reading of urandom for all domains, you must turn
92 on the global_ssp boolean. Disabled by default.
93 setsebool -P global_ssp 1

99 The SELinux process type afs_fsserver_t can manage files labeled with
100 the following file types. The paths listed are the default paths for
101 these file types. Note the processes UID still need to have DAC per‐
102 missions.
103 afs_config_t
105 /usr/afs/etc(/.*)?
107 /usr/afs/local(/.*)?
108 afs_files_t
110 /usr/afs(/.*)?
112 /vicepa
113 /vicepb
114 /vicepc
115 afs_logfile_t
117 /usr/afs/logs(/.*)?
119 initrc_tmp_t
121 mnt_t
124 /mnt(/[^/]*)
126 /mnt(/[^/]*)?
127 /rhev(/[^/]*)?

148 SELinux requires files to have an extended attribute to define the file
149 type.
150 You can see the context of a file using the -Z option to ls
152 Policy governs the access confined processes have to these files.
154 SELinux afs_fsserver policy is very flexible allowing users to setup
155 their afs_fsserver processes in as secure a method as possible.
156 The following file types are defined for afs_fsserver:
158 afs_fsserver_exec_t
162 - Set files with the afs_fsserver_exec_t type, if you want to transi‐
164 tion an executable to the afs_fsserver_t domain.
165 Paths:
168 /usr/afs/bin/salvager, /usr/afs/bin/volserver, /usr/afs/bin/file‐
169 server, /usr/afs/bin/dasalvager, /usr/afs/bin/davolserver,
170 /usr/afs/bin/dafileserver, /usr/afs/bin/salvageserver
171 Note: File context can be temporarily modified with the chcon command.
174 If you want to permanently change the file context you need to use the
175 semanage fcontext command. This will modify the SELinux labeling data‐
176 base. You will need to use restorecon to apply the labels.
177
180 semanage fcontext can also be used to manipulate default file context
181 mappings.
182 semanage permissive can also be used to manipulate whether or not a
184 process type is permissive.
185 semanage module can also be used to enable/disable/install/remove pol‐
187 icy modules.
188 semanage boolean can also be used to manipulate the booleans
190 system-config-selinux is a GUI tool available to customize SELinux pol‐
193 icy settings.
