NAME

6       qmail_smtpd_selinux   -   Security   Enhanced   Linux  Policy  for  the
7       qmail_smtpd processes
8

DESCRIPTION

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

22

ENTRYPOINTS

24       The    qmail_smtpd_t    SELinux   type   can   be   entered   via   the
25       qmail_smtpd_exec_t file type.
26
27       The default entrypoint paths for the qmail_smtpd_t domain are the  fol‐
28       lowing:
29
30       /var/qmail/bin/qmail-smtpd
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       qmail_smtpd  policy  is  very  flexible  allowing  users to setup their
40       qmail_smtpd processes in as secure a method as possible.
41
42       The following process types are defined for qmail_smtpd:
43
44       qmail_smtpd_t
45
46       Note: semanage permissive -a qmail_smtpd_t can  be  used  to  make  the
47       process  type qmail_smtpd_t permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.

51

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       qmail_smtpd policy is extremely flexible and has several booleans  that
55       allow  you to manipulate the policy and run qmail_smtpd with the tight‐
56       est access possible.
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 confined applications to run with kerberos, you
68       must turn on the allow_kerberos boolean. Enabled by default.
69
70       setsebool -P allow_kerberos 1
71
72
73
74       If you want to allow sysadm to debug or ptrace all processes, you  must
75       turn on the allow_ptrace boolean. Disabled by default.
76
77       setsebool -P allow_ptrace 1
78
79
80
81       If  you  want to allow all domains to have the kernel load modules, you
82       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
83       default.
84
85       setsebool -P domain_kernel_load_modules 1
86
87
88
89       If you want to allow all domains to execute in fips_mode, you must turn
90       on the fips_mode boolean. Enabled by default.
91
92       setsebool -P fips_mode 1
93
94
95
96       If you want to enable reading of urandom for all domains, you must turn
97       on the global_ssp boolean. Disabled by default.
98
99       setsebool -P global_ssp 1

MANAGED FILES

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

FILE CONTEXTS

137       SELinux requires files to have an extended attribute to define the file
138       type.
139
140       You can see the context of a file using the -Z option to ls
141
142       Policy  governs  the  access  confined  processes  have to these files.
143       SELinux qmail_smtpd policy is very flexible  allowing  users  to  setup
144       their qmail_smtpd processes in as secure a method as possible.
145
146       The following file types are defined for qmail_smtpd:
147
148
149
150       qmail_smtpd_exec_t
151
152       - Set files with the qmail_smtpd_exec_t type, if you want to transition
153       an executable to the qmail_smtpd_t domain.
154
155
156
157       Note: File context can be temporarily modified with the chcon  command.
158       If  you want to permanently change the file context you need to use the
159       semanage fcontext command.  This will modify the SELinux labeling data‐
160       base.  You will need to use restorecon to apply the labels.
161
162

COMMANDS

164       semanage  fcontext  can also be used to manipulate default file context
165       mappings.
166
167       semanage permissive can also be used to manipulate  whether  or  not  a
168       process type is permissive.
169
170       semanage  module can also be used to enable/disable/install/remove pol‐
171       icy modules.
172
173       semanage boolean can also be used to manipulate the booleans
174
175
176       system-config-selinux is a GUI tool available to customize SELinux pol‐
177       icy settings.
