6 afs_ptserver_selinux - Security Enhanced Linux Policy for the
7 afs_ptserver processes
8
10 Security-Enhanced Linux secures the afs_ptserver processes via flexible
11 mandatory access control.
12
13 The afs_ptserver processes execute with the afs_ptserver_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_ptserver_t
20
21
22
24 The afs_ptserver_t SELinux type can be entered via the
25 afs_ptserver_exec_t file type.
26
27 The default entrypoint paths for the afs_ptserver_t domain are the fol‐
28 lowing:
29
30 /usr/afs/bin/ptserver
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 afs_ptserver policy is very flexible allowing users to setup their
40 afs_ptserver processes in as secure a method as possible.
41
42 The following process types are defined for afs_ptserver:
43
44 afs_ptserver_t
45
46 Note: semanage permissive -a afs_ptserver_t can be used to make the
47 process type afs_ptserver_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 afs_ptserver policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run afs_ptserver with the tight‐
56 est access possible.
57
58
59
60 If you want to allow all domains to use other domains file descriptors,
61 you must turn on the allow_domain_fd_use boolean. Enabled by default.
62
63 setsebool -P allow_domain_fd_use 1
64
65
66
67 If you want to allow sysadm to debug or ptrace all processes, you must
68 turn on the allow_ptrace boolean. Disabled by default.
69
70 setsebool -P allow_ptrace 1
71
72
73
74 If you want to allow all domains to have the kernel load modules, you
75 must turn on the domain_kernel_load_modules boolean. Disabled by
76 default.
77
78 setsebool -P domain_kernel_load_modules 1
79
80
81
82 If you want to allow all domains to execute in fips_mode, you must turn
83 on the fips_mode boolean. Enabled by default.
84
85 setsebool -P fips_mode 1
86
87
88
89 If you want to enable reading of urandom for all domains, you must turn
90 on the global_ssp boolean. Disabled by default.
91
92 setsebool -P global_ssp 1
93
94
95
97 The SELinux process type afs_ptserver_t can manage files labeled with
98 the following file types. The paths listed are the default paths for
99 these file types. Note the processes UID still need to have DAC per‐
100 missions.
101
102 afs_logfile_t
103
104 /usr/afs/logs(/.*)?
105
106 afs_pt_db_t

138 SELinux requires files to have an extended attribute to define the file
139 type.
140
141 You can see the context of a file using the -Z option to ls
142
143 Policy governs the access confined processes have to these files.
144 SELinux afs_ptserver policy is very flexible allowing users to setup
145 their afs_ptserver processes in as secure a method as possible.
146
147 The following file types are defined for afs_ptserver:
148
149
150
151 afs_ptserver_exec_t
152
153 - Set files with the afs_ptserver_exec_t type, if you want to transi‐
154 tion an executable to the afs_ptserver_t domain.
155
156
157
158 Note: File context can be temporarily modified with the chcon command.
159 If you want to permanently change the file context you need to use the
160 semanage fcontext command. This will modify the SELinux labeling data‐
161 base. You will need to use restorecon to apply the labels.
162
163
165 semanage fcontext can also be used to manipulate default file context
166 mappings.
167
168 semanage permissive can also be used to manipulate whether or not a
169 process type is permissive.
170
171 semanage module can also be used to enable/disable/install/remove pol‐
172 icy modules.
173
174 semanage boolean can also be used to manipulate the booleans
175
176
177 system-config-selinux is a GUI tool available to customize SELinux pol‐
178 icy settings.
