NAME

6       qmail_clean_selinux   -   Security   Enhanced   Linux  Policy  for  the
7       qmail_clean processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the qmail_clean processes via  flexible
11       mandatory access control.
12
13       The  qmail_clean processes execute with the qmail_clean_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_clean_t

22

ENTRYPOINTS

24       The    qmail_clean_t    SELinux   type   can   be   entered   via   the
25       qmail_clean_exec_t file type.
26
27       The default entrypoint paths for the qmail_clean_t domain are the  fol‐
28       lowing:
29
30       /var/qmail/bin/qmail-clean
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_clean  policy  is  very  flexible  allowing  users to setup their
40       qmail_clean processes in as secure a method as possible.
41
42       The following process types are defined for qmail_clean:
43
44       qmail_clean_t
45
46       Note: semanage permissive -a qmail_clean_t can  be  used  to  make  the
47       process  type qmail_clean_t permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.
50
51

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       qmail_clean policy is extremely flexible and has several booleans  that
55       allow  you to manipulate the policy and run qmail_clean with the tight‐
56       est access possible.
57
58
59
60       If you want to deny any process from ptracing or  debugging  any  other
61       processes,  you  must  turn  on  the  deny_ptrace  boolean.  Enabled by
62       default.
63
64       setsebool -P deny_ptrace 1
65
66
67
68       If you want to allow any process  to  mmap  any  file  on  system  with
69       attribute  file_type,  you must turn on the domain_can_mmap_files bool‐
70       ean. Enabled by default.
71
72       setsebool -P domain_can_mmap_files 1
73
74
75
76       If you want to allow all domains write to kmsg_device, while kernel  is
77       executed  with  systemd.log_target=kmsg parameter, you must turn on the
78       domain_can_write_kmsg boolean. Disabled by default.
79
80       setsebool -P domain_can_write_kmsg 1
81
82
83
84       If you want to allow all domains to use other domains file descriptors,
85       you must turn on the domain_fd_use boolean. Enabled by default.
86
87       setsebool -P domain_fd_use 1
88
89
90
91       If  you  want to allow all domains to have the kernel load modules, you
92       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
93       default.
94
95       setsebool -P domain_kernel_load_modules 1
96
97
98
99       If you want to allow all domains to execute in fips_mode, you must turn
100       on the fips_mode boolean. Enabled by default.
101
102       setsebool -P fips_mode 1
103
104
105
106       If you want to enable reading of urandom for all domains, you must turn
107       on the global_ssp boolean. Disabled by default.
108
109       setsebool -P global_ssp 1
110

FILE CONTEXTS

114       SELinux requires files to have an extended attribute to define the file
115       type.
116
117       You can see the context of a file using the -Z option to ls
118
119       Policy governs the access  confined  processes  have  to  these  files.
120       SELinux  qmail_clean  policy  is  very flexible allowing users to setup
121       their qmail_clean processes in as secure a method as possible.
122
123       The following file types are defined for qmail_clean:
124
125
126
127       qmail_clean_exec_t
128
129       - Set files with the qmail_clean_exec_t type, if you want to transition
130       an executable to the qmail_clean_t domain.
131
132
133
134       Note:  File context can be temporarily modified with the chcon command.
135       If you want to permanently change the file context you need to use  the
136       semanage fcontext command.  This will modify the SELinux labeling data‐
137       base.  You will need to use restorecon to apply the labels.
138
139

COMMANDS

141       semanage fcontext can also be used to manipulate default  file  context
142       mappings.
143
144       semanage  permissive  can  also  be used to manipulate whether or not a
145       process type is permissive.
146
147       semanage module can also be used to enable/disable/install/remove  pol‐
148       icy modules.
149
150       semanage boolean can also be used to manipulate the booleans
151
152
153       system-config-selinux is a GUI tool available to customize SELinux pol‐
154       icy settings.
