NAME

6       ptchown_selinux  -  Security Enhanced Linux Policy for the ptchown pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  ptchown  processes  via  flexible
11       mandatory access control.
12
13       The  ptchown processes execute with the ptchown_t SELinux type. You can
14       check if you have these processes running by executing the  ps  command
15       with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep ptchown_t
20
21
22

ENTRYPOINTS

24       The  ptchown_t  SELinux type can be entered via the ptchown_exec_t file
25       type.
26
27       The default entrypoint paths for the ptchown_t domain are  the  follow‐
28       ing:
29
30       /usr/libexec/pt_chown
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       ptchown  policy  is very flexible allowing users to setup their ptchown
40       processes in as secure a method as possible.
41
42       The following process types are defined for ptchown:
43
44       ptchown_t
45
46       Note: semanage permissive -a ptchown_t can be used to make the  process
47       type  ptchown_t  permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.

51

BOOLEANS

53       SELinux policy is customizable based on least access required.  ptchown
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run ptchown with the tightest access possi‐
56       ble.
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

MANAGED FILES

97       The SELinux process type ptchown_t can manage files  labeled  with  the
98       following file types.  The paths listed are the default paths for these
99       file types.  Note the processes UID still need to have DAC permissions.
100
101       anon_inodefs_t
102
103
104       initrc_tmp_t
105
106
107       mnt_t
108
109            /mnt(/[^/]*)
110            /mnt(/[^/]*)?
111            /rhev(/[^/]*)?
112            /media(/[^/]*)
113            /media(/[^/]*)?
114            /etc/rhgb(/.*)?
115            /media/.hal-.*
116            /net
117            /afs
118            /rhev
119            /misc
120
121       tmp_t
122
123            /tmp
124            /usr/tmp
125            /var/tmp
126            /tmp-inst
127            /var/tmp-inst
128            /var/tmp/vi.recover

FILE CONTEXTS

132       SELinux requires files to have an extended attribute to define the file
133       type.
134
135       You can see the context of a file using the -Z option to ls
136
137       Policy  governs  the  access  confined  processes  have to these files.
138       SELinux ptchown policy is very flexible allowing users to  setup  their
139       ptchown processes in as secure a method as possible.
140
141       The following file types are defined for ptchown:
142
143
144
145       ptchown_exec_t
146
147       -  Set files with the ptchown_exec_t type, if you want to transition an
148       executable to the ptchown_t domain.
149
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.
