NAME

6       qmail_remote_selinux   -   Security   Enhanced  Linux  Policy  for  the
7       qmail_remote processes
8

DESCRIPTION

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

22

ENTRYPOINTS

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

MANAGED FILES

114       The  SELinux  process type qmail_remote_t can manage files labeled with
115       the following file types.  The paths listed are the default  paths  for
116       these  file  types.  Note the processes UID still need to have DAC per‐
117       missions.
118
119       qmail_spool_t
120
121            /var/qmail/queue(/.*)?
122
123

FILE CONTEXTS

125       SELinux requires files to have an extended attribute to define the file
126       type.
127
128       You can see the context of a file using the -Z option to ls
129
130       Policy  governs  the  access  confined  processes  have to these files.
131       SELinux qmail_remote policy is very flexible allowing  users  to  setup
132       their qmail_remote processes in as secure a method as possible.
133
134       The following file types are defined for qmail_remote:
135
136
137
138       qmail_remote_exec_t
139
140       -  Set  files with the qmail_remote_exec_t type, if you want to transi‐
141       tion an executable to the qmail_remote_t domain.
142
143
144
145       Note: File context can be temporarily modified with the chcon  command.
146       If  you want to permanently change the file context you need to use the
147       semanage fcontext command.  This will modify the SELinux labeling data‐
148       base.  You will need to use restorecon to apply the labels.
149
150

COMMANDS

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