6 svc_run_selinux - Security Enhanced Linux Policy for the svc_run pro‐
7 cesses
8
10 Security-Enhanced Linux secures the svc_run processes via flexible
11 mandatory access control.
12 The svc_run processes execute with the svc_run_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep svc_run_t
20
24 The svc_run_t SELinux type can be entered via the svc_run_exec_t file
25 type.
26 The default entrypoint paths for the svc_run_t domain are the follow‐
28 ing:
29 /var/service/.*/run.*, /var/service/.*/log/run, /var/qmail/super‐
31 vise/.*/run, /var/qmail/supervise/.*/log/run, /usr/bin/envdir,
32 /usr/bin/fghack, /usr/bin/setlock, /var/axfrdns/run, /var/tinydns/run,
33 /usr/bin/pgrphack, /var/dnscache/run, /usr/bin/envuidgid,
34 /usr/bin/setuidgid, /usr/bin/softlimit, /var/axfrdns/log/run,
35 /var/tinydns/log/run, /var/dnscache/log/run
36
38 SELinux defines process types (domains) for each process running on the
39 system
40 You can see the context of a process using the -Z option to ps
42 Policy governs the access confined processes have to files. SELinux
44 svc_run policy is very flexible allowing users to setup their svc_run
45 processes in as secure a method as possible.
46 The following process types are defined for svc_run:
48 svc_run_t
50 Note: semanage permissive -a svc_run_t can be used to make the process
52 type svc_run_t permissive. SELinux does not deny access to permissive
53 process types, but the AVC (SELinux denials) messages are still gener‐
54 ated.
55
58 SELinux policy is customizable based on least access required. svc_run
59 policy is extremely flexible and has several booleans that allow you to
60 manipulate the policy and run svc_run with the tightest access possi‐
61 ble.
62 If you want to allow all domains to use other domains file descriptors,
66 you must turn on the allow_domain_fd_use boolean. Enabled by default.
67 setsebool -P allow_domain_fd_use 1
69 If you want to allow sysadm to debug or ptrace all processes, you must
73 turn on the allow_ptrace boolean. Disabled by default.
74 setsebool -P allow_ptrace 1
76 If you want to allow all domains to have the kernel load modules, you
80 must turn on the domain_kernel_load_modules boolean. Disabled by
81 default.
82 setsebool -P domain_kernel_load_modules 1
84 If you want to allow all domains to execute in fips_mode, you must turn
88 on the fips_mode boolean. Enabled by default.
89 setsebool -P fips_mode 1
91 If you want to enable reading of urandom for all domains, you must turn
95 on the global_ssp boolean. Disabled by default.
96 setsebool -P global_ssp 1

102 The SELinux process type svc_run_t can manage files labeled with the
103 following file types. The paths listed are the default paths for these
104 file types. Note the processes UID still need to have DAC permissions.
105 initrc_tmp_t
107 mnt_t
110 /mnt(/[^/]*)
112 /mnt(/[^/]*)?
113 /rhev(/[^/]*)?
114 /media(/[^/]*)
115 /media(/[^/]*)?
116 /etc/rhgb(/.*)?
117 /media/.hal-.*
118 /net
119 /afs
120 /rhev
121 /misc
122 tmp_t
124 /tmp
126 /usr/tmp
127 /var/tmp
128 /tmp-inst
129 /var/tmp-inst
130 /var/tmp/vi.recover
131
134 SELinux requires files to have an extended attribute to define the file
135 type.
136 You can see the context of a file using the -Z option to ls
138 Policy governs the access confined processes have to these files.
140 SELinux svc_run policy is very flexible allowing users to setup their
141 svc_run processes in as secure a method as possible.
142 The following file types are defined for svc_run:
144 svc_run_exec_t
148 - Set files with the svc_run_exec_t type, if you want to transition an
150 executable to the svc_run_t domain.
151 Paths:
154 /var/service/.*/run.*, /var/service/.*/log/run, /var/qmail/super‐
155 vise/.*/run, /var/qmail/supervise/.*/log/run, /usr/bin/envdir,
156 /usr/bin/fghack, /usr/bin/setlock, /var/axfrdns/run,
157 /var/tinydns/run, /usr/bin/pgrphack, /var/dnscache/run,
158 /usr/bin/envuidgid, /usr/bin/setuidgid, /usr/bin/softlimit,
159 /var/axfrdns/log/run, /var/tinydns/log/run, /var/dnscache/log/run
160 Note: File context can be temporarily modified with the chcon command.
163 If you want to permanently change the file context you need to use the
164 semanage fcontext command. This will modify the SELinux labeling data‐
165 base. You will need to use restorecon to apply the labels.
166
169 semanage fcontext can also be used to manipulate default file context
170 mappings.
171 semanage permissive can also be used to manipulate whether or not a
173 process type is permissive.
174 semanage module can also be used to enable/disable/install/remove pol‐
176 icy modules.
177 semanage boolean can also be used to manipulate the booleans
179 system-config-selinux is a GUI tool available to customize SELinux pol‐
182 icy settings.
