NAME

6       chfn_selinux - Security Enhanced Linux Policy for the chfn processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the chfn processes via flexible manda‐
10       tory access control.
11
12       The chfn processes execute with the chfn_t SELinux type. You can  check
13       if  you  have  these processes running by executing the ps command with
14       the -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep chfn_t

21

ENTRYPOINTS

23       The chfn_t SELinux type can be entered via the chfn_exec_t file type.
24
25       The default entrypoint paths for the chfn_t domain are the following:
26
27       /usr/bin/chfn, /usr/bin/chsh
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       chfn policy is very flexible allowing users to setup  their  chfn  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for chfn:
40
41       chfn_t
42
43       Note:  semanage  permissive  -a  chfn_t can be used to make the process
44       type chfn_t permissive. SELinux does  not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.

48

BOOLEANS

50       SELinux policy is customizable based on least  access  required.   chfn
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run chfn with the tightest access possible.
53
54
55
56       If you want to allow all domains to execute in fips_mode, you must turn
57       on the fips_mode boolean. Enabled by default.
58
59       setsebool -P fips_mode 1
60
61
62
63       If  you  want  to allow confined applications to run with kerberos, you
64       must turn on the kerberos_enabled boolean. Disabled by default.
65
66       setsebool -P kerberos_enabled 1
67
68
69
70       If you want to allow system to run with  NIS,  you  must  turn  on  the
71       nis_enabled boolean. Disabled by default.
72
73       setsebool -P nis_enabled 1

MANAGED FILES

78       The  SELinux process type chfn_t can manage files labeled with the fol‐
79       lowing file types.  The paths listed are the default  paths  for  these
80       file types.  Note the processes UID still need to have DAC permissions.
81
82       faillog_t
83
84            /var/log/btmp.*
85            /var/log/faillog.*
86            /var/log/tallylog.*
87            /var/run/faillock(/.*)?
88
89       lastlog_t
90
91            /var/log/lastlog.*
92
93       security_t
94
95            /selinux

FILE CONTEXTS

99       SELinux requires files to have an extended attribute to define the file
100       type.
101
102       You can see the context of a file using the -Z option to ls
103
104       Policy governs the access  confined  processes  have  to  these  files.
105       SELinux chfn policy is very flexible allowing users to setup their chfn
106       processes in as secure a method as possible.
107
108       The following file types are defined for chfn:
109
110
111
112       chfn_exec_t
113
114       - Set files with the chfn_exec_t type, if you  want  to  transition  an
115       executable to the chfn_t domain.
116
117
118       Paths:
119            /usr/bin/chfn, /usr/bin/chsh
120
121
122       Note:  File context can be temporarily modified with the chcon command.
123       If you want to permanently change the file context you need to use  the
124       semanage fcontext command.  This will modify the SELinux labeling data‐
125       base.  You will need to use restorecon to apply the labels.
126
127

COMMANDS

129       semanage fcontext can also be used to manipulate default  file  context
130       mappings.
131
132       semanage  permissive  can  also  be used to manipulate whether or not a
133       process type is permissive.
134
135       semanage module can also be used to enable/disable/install/remove  pol‐
136       icy modules.
137
138       semanage boolean can also be used to manipulate the booleans
139
140
141       system-config-selinux is a GUI tool available to customize SELinux pol‐
142       icy settings.
