6 ptchown_selinux - Security Enhanced Linux Policy for the ptchown pro‐
7 cesses
8
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
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/lib/pt_chown, /usr/libexec/pt_chown
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 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.
50
51
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 execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1

65
66
68 The SELinux process type ptchown_t can manage files labeled with the
69 following file types. The paths listed are the default paths for these
70 file types. Note the processes UID still need to have DAC permissions.
71
72 anon_inodefs_t
73
74
75
77 SELinux requires files to have an extended attribute to define the file
78 type.
79
80 You can see the context of a file using the -Z option to ls
81
82 Policy governs the access confined processes have to these files.
83 SELinux ptchown policy is very flexible allowing users to setup their
84 ptchown processes in as secure a method as possible.
85
86 The following file types are defined for ptchown:
87
88
89
90 ptchown_exec_t
91
92 - Set files with the ptchown_exec_t type, if you want to transition an
93 executable to the ptchown_t domain.
94
95
96 Paths:
97 /usr/lib/pt_chown, /usr/libexec/pt_chown
98
99
100 Note: File context can be temporarily modified with the chcon command.
101 If you want to permanently change the file context you need to use the
102 semanage fcontext command. This will modify the SELinux labeling data‐
103 base. You will need to use restorecon to apply the labels.
104
105
107 semanage fcontext can also be used to manipulate default file context
108 mappings.
109
110 semanage permissive can also be used to manipulate whether or not a
111 process type is permissive.
112
113 semanage module can also be used to enable/disable/install/remove pol‐
114 icy modules.
115
116 semanage boolean can also be used to manipulate the booleans
117
118
119 system-config-selinux is a GUI tool available to customize SELinux pol‐
120 icy settings.
