NAME

6       afs_ptserver_selinux   -   Security   Enhanced  Linux  Policy  for  the
7       afs_ptserver processes
8

DESCRIPTION

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

ENTRYPOINTS

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, /usr/libexec/openafs/ptserver
31

PROCESS TYPES

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

BOOLEANS

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 deny any process from ptracing or  debugging  any  other
61       processes,  you  must  turn  on  the  deny_ptrace  boolean.  Enabled by
62       default.
63
64       setsebool -P deny_ptrace 1
65
66
67
68       If you want to allow any process  to  mmap  any  file  on  system  with
69       attribute  file_type,  you must turn on the domain_can_mmap_files bool‐
70       ean. Enabled by default.
71
72       setsebool -P domain_can_mmap_files 1
73
74
75
76       If you want to allow all domains write to kmsg_device, while kernel  is
77       executed  with  systemd.log_target=kmsg parameter, you must turn on the
78       domain_can_write_kmsg boolean. Disabled by default.
79
80       setsebool -P domain_can_write_kmsg 1
81
82
83
84       If you want to allow all domains to use other domains file descriptors,
85       you must turn on the domain_fd_use boolean. Enabled by default.
86
87       setsebool -P domain_fd_use 1
88
89
90
91       If  you  want to allow all domains to have the kernel load modules, you
92       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
93       default.
94
95       setsebool -P domain_kernel_load_modules 1
96
97
98
99       If you want to allow all domains to execute in fips_mode, you must turn
100       on the fips_mode boolean. Enabled by default.
101
102       setsebool -P fips_mode 1
103
104
105
106       If you want to enable reading of urandom for all domains, you must turn
107       on the global_ssp boolean. Disabled by default.
108
109       setsebool -P global_ssp 1

MANAGED FILES

114       The  SELinux  process type afs_ptserver_t can manage files labeled with
115       the following file types.  The paths listed are the default  paths  for
116       these  file  types.  Note the processes UID still need to have DAC per‐
117       missions.
118
119       afs_logfile_t
120
121            /usr/afs/logs(/.*)?
122
123       afs_pt_db_t
124
125            /usr/afs/db/pr.*
126
127

FILE CONTEXTS

129       SELinux requires files to have an extended attribute to define the file
130       type.
131
132       You can see the context of a file using the -Z option to ls
133
134       Policy  governs  the  access  confined  processes  have to these files.
135       SELinux afs_ptserver policy is very flexible allowing  users  to  setup
136       their afs_ptserver processes in as secure a method as possible.
137
138       The following file types are defined for afs_ptserver:
139
140
141
142       afs_ptserver_exec_t
143
144       -  Set  files with the afs_ptserver_exec_t type, if you want to transi‐
145       tion an executable to the afs_ptserver_t domain.
146
147
148       Paths:
149            /usr/afs/bin/ptserver, /usr/libexec/openafs/ptserver
150
151
152       Note: File context can be temporarily modified with the chcon  command.
153       If  you want to permanently change the file context you need to use the
154       semanage fcontext command.  This will modify the SELinux labeling data‐
155       base.  You will need to use restorecon to apply the labels.
156
157

COMMANDS

159       semanage  fcontext  can also be used to manipulate default file context
160       mappings.
161
162       semanage permissive can also be used to manipulate  whether  or  not  a
163       process type is permissive.
164
165       semanage  module can also be used to enable/disable/install/remove pol‐
166       icy modules.
167
168       semanage boolean can also be used to manipulate the booleans
169
170
171       system-config-selinux is a GUI tool available to customize SELinux pol‐
172       icy settings.
