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
19

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 users to resolve user passwd entries directly from
57       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
58       gin_nsswitch_use_ldap boolean. Disabled by default.
59
60       setsebool -P authlogin_nsswitch_use_ldap 1
61
62
63
64       If you want to allow all domains to execute in fips_mode, you must turn
65       on the fips_mode boolean. Enabled by default.
66
67       setsebool -P fips_mode 1
68
69
70
71       If  you  want  to allow confined applications to run with kerberos, you
72       must turn on the kerberos_enabled boolean. Enabled by default.
73
74       setsebool -P kerberos_enabled 1
75
76
77
78       If you want to allow system to run with  NIS,  you  must  turn  on  the
79       nis_enabled boolean. Disabled by default.
80
81       setsebool -P nis_enabled 1
82
83
84
85       If  you  want to allow confined applications to use nscd shared memory,
86       you must turn on the nscd_use_shm boolean. Enabled by default.
87
88       setsebool -P nscd_use_shm 1

MANAGED FILES

93       The SELinux process type chfn_t can manage files labeled with the  fol‐
94       lowing  file  types.   The paths listed are the default paths for these
95       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

152       SELinux requires files to have an extended attribute to define the file
153       type.
154
155       You can see the context of a file using the -Z option to ls
156
157       Policy  governs  the  access  confined  processes  have to these files.
158       SELinux chfn policy is very flexible allowing users to setup their chfn
159       processes in as secure a method as possible.
160
161       The following file types are defined for chfn:
162
163
164
165       chfn_exec_t
166
167       -  Set  files  with  the chfn_exec_t type, if you want to transition an
168       executable to the chfn_t domain.
169
170
171       Paths:
172            /usr/bin/chfn, /usr/bin/chsh
173
174
175       Note: File context can be temporarily modified with the chcon  command.
176       If  you want to permanently change the file context you need to use the
177       semanage fcontext command.  This will modify the SELinux labeling data‐
178       base.  You will need to use restorecon to apply the labels.
179
180

COMMANDS

182       semanage  fcontext  can also be used to manipulate default file context
183       mappings.
184
185       semanage permissive can also be used to manipulate  whether  or  not  a
186       process type is permissive.
187
188       semanage  module can also be used to enable/disable/install/remove pol‐
189       icy modules.
190
191       semanage boolean can also be used to manipulate the booleans
192
193
194       system-config-selinux is a GUI tool available to customize SELinux pol‐
195       icy settings.
