6 qmail_send_selinux - Security Enhanced Linux Policy for the qmail_send
7 processes
8
10 Security-Enhanced Linux secures the qmail_send processes via flexible
11 mandatory access control.
12 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 For example:
18 ps -eZ | grep qmail_send_t
20
24 The qmail_send_t SELinux type can be entered via the qmail_send_exec_t
25 file type.
26 The default entrypoint paths for the qmail_send_t domain are the fol‐
28 lowing:
29 /var/qmail/bin/qmail-send
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for qmail_send:
43 qmail_send_t
45 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
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 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64
68 The SELinux process type qmail_send_t can manage files labeled with the
69 following file types. The paths listed are the default paths for these
70 file types. Note the processes UID still need to have DAC permissions.
71 qmail_spool_t
73 /var/qmail/queue(/.*)?
75
78 SELinux requires files to have an extended attribute to define the file
79 type.
80 You can see the context of a file using the -Z option to ls
82 Policy governs the access confined processes have to these files.
84 SELinux qmail_send policy is very flexible allowing users to setup
85 their qmail_send processes in as secure a method as possible.
86 STANDARD FILE CONTEXT
88 SELinux defines the file context types for the qmail_send, if you
90 wanted to store files with these types in a different paths, you need
91 to execute the semanage command to specify alternate labeling and then
92 use restorecon to put the labels on disk.
93 semanage fcontext -a -t qmail_send_exec_t '/srv/qmail_send/con‐
95 tent(/.*)?'
96 restorecon -R -v /srv/myqmail_send_content
97 Note: SELinux often uses regular expressions to specify labels that
99 match multiple files.
100 The following file types are defined for qmail_send:
102 qmail_send_exec_t
106 - Set files with the qmail_send_exec_t type, if you want to transition
108 an executable to the qmail_send_t domain.
109 Note: File context can be temporarily modified with the chcon command.
113 If you want to permanently change the file context you need to use the
114 semanage fcontext command. This will modify the SELinux labeling data‐
115 base. You will need to use restorecon to apply the labels.
116
119 semanage fcontext can also be used to manipulate default file context
120 mappings.
121 semanage permissive can also be used to manipulate whether or not a
123 process type is permissive.
124 semanage module can also be used to enable/disable/install/remove pol‐
126 icy modules.
127 semanage boolean can also be used to manipulate the booleans
129 system-config-selinux is a GUI tool available to customize SELinux pol‐
132 icy settings.
