NAME

6       qmail_send_selinux  - Security Enhanced Linux Policy for the qmail_send
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the qmail_send processes  via  flexible
11       mandatory access control.
12
13       The  qmail_send  processes  execute with the qmail_send_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_send_t
20
21
22

ENTRYPOINTS

24       The  qmail_send_t SELinux type can be entered via the qmail_send_exec_t
25       file type.
26
27       The default entrypoint paths for the qmail_send_t domain are  the  fol‐
28       lowing:
29
30       /var/qmail/bin/qmail-send
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_send  policy  is  very  flexible  allowing  users  to setup their
40       qmail_send processes in as secure a method as possible.
41
42       The following process types are defined for qmail_send:
43
44       qmail_send_t
45
46       Note: semanage permissive -a qmail_send_t  can  be  used  to  make  the
47       process  type  qmail_send_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_send policy is extremely flexible and has several  booleans  that
55       allow you to manipulate the policy and run qmail_send with the tightest
56       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
111
112

MANAGED FILES

114       The SELinux process type qmail_send_t can manage files labeled with the
115       following file types.  The paths listed are the default paths for these
116       file types.  Note the processes UID still need to have DAC permissions.
117
118       qmail_spool_t
119
120            /var/qmail/queue(/.*)?
121
122

FILE CONTEXTS

124       SELinux requires files to have an extended attribute to define the file
125       type.
126
127       You can see the context of a file using the -Z option to ls
128
129       Policy governs the access  confined  processes  have  to  these  files.
130       SELinux  qmail_send  policy  is  very  flexible allowing users to setup
131       their qmail_send processes in as secure a method as possible.
132
133       The following file types are defined for qmail_send:
134
135
136
137       qmail_send_exec_t
138
139       - Set files with the qmail_send_exec_t type, if you want to  transition
140       an executable to the qmail_send_t domain.
141
142
143
144       Note:  File context can be temporarily modified with the chcon command.
145       If you want to permanently change the file context you need to use  the
146       semanage fcontext command.  This will modify the SELinux labeling data‐
147       base.  You will need to use restorecon to apply the labels.
148
149

COMMANDS

151       semanage fcontext can also be used to manipulate default  file  context
152       mappings.
153
154       semanage  permissive  can  also  be used to manipulate whether or not a
155       process type is permissive.
156
157       semanage module can also be used to enable/disable/install/remove  pol‐
158       icy modules.
159
160       semanage boolean can also be used to manipulate the booleans
161
162
163       system-config-selinux is a GUI tool available to customize SELinux pol‐
164       icy settings.
