6 spamc_selinux - Security Enhanced Linux Policy for the spamc processes
7
9 Security-Enhanced Linux secures the spamc processes via flexible manda‐
10 tory access control.
11 The spamc processes execute with the spamc_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15 For example:
17 ps -eZ | grep spamc_t
19
23 The spamc_t SELinux type can be entered via the spamc_exec_t file type.
24 The default entrypoint paths for the spamc_t domain are the following:
26 /usr/bin/razor.*, /usr/bin/pyzor, /usr/bin/spamc, /usr/bin/sa-learn,
28 /usr/bin/spamassassin
29
31 SELinux defines process types (domains) for each process running on the
32 system
33 You can see the context of a process using the -Z option to ps
35 Policy governs the access confined processes have to files. SELinux
37 spamc policy is very flexible allowing users to setup their spamc pro‐
38 cesses in as secure a method as possible.
39 The following process types are defined for spamc:
41 spamc_t
43 Note: semanage permissive -a spamc_t can be used to make the process
45 type spamc_t permissive. SELinux does not deny access to permissive
46 process types, but the AVC (SELinux denials) messages are still gener‐
47 ated.
48
51 SELinux policy is customizable based on least access required. spamc
52 policy is extremely flexible and has several booleans that allow you to
53 manipulate the policy and run spamc with the tightest access possible.
54 If you want to allow all domains to execute in fips_mode, you must turn
58 on the fips_mode boolean. Enabled by default.
59 setsebool -P fips_mode 1
61 If you want to allow user spamassassin clients to use the network, you
65 must turn on the spamassassin_can_network boolean. Disabled by default.
66 setsebool -P spamassassin_can_network 1
68
72 The SELinux process type spamc_t can manage files labeled with the fol‐
73 lowing file types. The paths listed are the default paths for these
74 file types. Note the processes UID still need to have DAC permissions.

120 SELinux requires files to have an extended attribute to define the file
121 type.
122 You can see the context of a file using the -Z option to ls
124 Policy governs the access confined processes have to these files.
126 SELinux spamc policy is very flexible allowing users to setup their
127 spamc processes in as secure a method as possible.
128 STANDARD FILE CONTEXT
130 SELinux defines the file context types for the spamc, if you wanted to
132 store files with these types in a diffent paths, you need to execute
133 the semanage command to sepecify alternate labeling and then use
134 restorecon to put the labels on disk.
135 semanage fcontext -a -t spamc_tmp_t '/srv/myspamc_content(/.*)?'
137 restorecon -R -v /srv/myspamc_content
138 Note: SELinux often uses regular expressions to specify labels that
140 match multiple files.
141 The following file types are defined for spamc:
143 spamc_exec_t
147 - Set files with the spamc_exec_t type, if you want to transition an
149 executable to the spamc_t domain.
150 Paths:
153 /usr/bin/razor.*, /usr/bin/pyzor, /usr/bin/spamc, /usr/bin/sa-
154 learn, /usr/bin/spamassassin
155 spamc_home_t
158 - Set files with the spamc_home_t type, if you want to store spamc
160 files in the users home directory.
161 Paths:
164 /root/.pyzor(/.*)?, /root/.razor(/.*)?, /root/.spamd(/.*)?,
165 /root/.spamassassin(/.*)?, /home/[^/]+/.pyzor(/.*)?,
166 /home/[^/]+/.razor(/.*)?, /home/[^/]+/.spamd(/.*)?,
167 /home/[^/]+/.spamassassin(/.*)?
168 spamc_tmp_t
171 - Set files with the spamc_tmp_t type, if you want to store spamc tem‐
173 porary files in the /tmp directories.
174 Note: File context can be temporarily modified with the chcon command.
178 If you want to permanently change the file context you need to use the
179 semanage fcontext command. This will modify the SELinux labeling data‐
180 base. You will need to use restorecon to apply the labels.
181
184 semanage fcontext can also be used to manipulate default file context
185 mappings.
186 semanage permissive can also be used to manipulate whether or not a
188 process type is permissive.
189 semanage module can also be used to enable/disable/install/remove pol‐
191 icy modules.
192 semanage boolean can also be used to manipulate the booleans
194 system-config-selinux is a GUI tool available to customize SELinux pol‐
197 icy settings.
