6 varnishlog_selinux - Security Enhanced Linux Policy for the varnishlog
7 processes
8
10 Security-Enhanced Linux secures the varnishlog processes via flexible
11 mandatory access control.
12 The varnishlog processes execute with the varnishlog_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 varnishlog_t
20
24 The varnishlog_t SELinux type can be entered via the varnishlog_exec_t
25 file type.
26 The default entrypoint paths for the varnishlog_t domain are the fol‐
28 lowing:
29 /usr/bin/varnishlog, /usr/bin/varnisncsa
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 varnishlog policy is very flexible allowing users to setup their var‐
40 nishlog processes in as secure a method as possible.
41 The following process types are defined for varnishlog:
43 varnishlog_t
45 Note: semanage permissive -a varnishlog_t can be used to make the
47 process type varnishlog_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. var‐
54 nishlog policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run varnishlog with the tightest
56 access possible.
57 If you want to allow all daemons to write corefiles to /, you must turn
61 on the allow_daemons_dump_core boolean. Disabled by default.
62 setsebool -P allow_daemons_dump_core 1
64 If you want to allow all daemons to use tcp wrappers, you must turn on
68 the allow_daemons_use_tcp_wrapper boolean. Disabled by default.
69 setsebool -P allow_daemons_use_tcp_wrapper 1
71 If you want to allow all daemons the ability to read/write terminals,
75 you must turn on the allow_daemons_use_tty boolean. Disabled by
76 default.
77 setsebool -P allow_daemons_use_tty 1
79 If you want to allow all domains to use other domains file descriptors,
83 you must turn on the allow_domain_fd_use boolean. Enabled by default.

90 turn on the allow_ptrace boolean. Disabled by default.
91 setsebool -P allow_ptrace 1

97 daemons_enable_cluster_mode boolean. Disabled by default.
98 setsebool -P daemons_enable_cluster_mode 1
100 If you want to allow all domains to have the kernel load modules, you
104 must turn on the domain_kernel_load_modules boolean. Disabled by
105 default.
106 setsebool -P domain_kernel_load_modules 1
108 If you want to allow all domains to execute in fips_mode, you must turn
112 on the fips_mode boolean. Enabled by default.
113 setsebool -P fips_mode 1
115 If you want to enable reading of urandom for all domains, you must turn
119 on the global_ssp boolean. Disabled by default.
120 setsebool -P global_ssp 1
122 If you want to enable support for upstart as the init program, you must
126 turn on the init_upstart boolean. Enabled by default.
127 setsebool -P init_upstart 1

133 The SELinux process type varnishlog_t can manage files labeled with the
134 following file types. The paths listed are the default paths for these
135 file types. Note the processes UID still need to have DAC permissions.

205 SELinux requires files to have an extended attribute to define the file
206 type.
207 You can see the context of a file using the -Z option to ls
209 Policy governs the access confined processes have to these files.
211 SELinux varnishlog policy is very flexible allowing users to setup
212 their varnishlog processes in as secure a method as possible.
213 STANDARD FILE CONTEXT
215 SELinux defines the file context types for the varnishlog, if you
217 wanted to store files with these types in a diffent paths, you need to
218 execute the semanage command to sepecify alternate labeling and then
219 use restorecon to put the labels on disk.
220 semanage fcontext -a -t varnishlog_var_run_t '/srv/myvarnishlog_con‐
222 tent(/.*)?'
223 restorecon -R -v /srv/myvarnishlog_content
224 Note: SELinux often uses regular expressions to specify labels that
226 match multiple files.
227 The following file types are defined for varnishlog:
229 varnishlog_exec_t
233 - Set files with the varnishlog_exec_t type, if you want to transition
235 an executable to the varnishlog_t domain.
236 Paths:
239 /usr/bin/varnishlog, /usr/bin/varnisncsa
240 varnishlog_initrc_exec_t
243 - Set files with the varnishlog_initrc_exec_t type, if you want to
245 transition an executable to the varnishlog_initrc_t domain.
246 Paths:
249 /etc/rc.d/init.d/varnishlog, /etc/rc.d/init.d/varnishncsa
250 varnishlog_log_t
253 - Set files with the varnishlog_log_t type, if you want to treat the
255 data as varnishlog log data, usually stored under the /var/log direc‐
256 tory.
257 varnishlog_var_run_t
261 - Set files with the varnishlog_var_run_t type, if you want to store
263 the varnishlog files under the /run or /var/run directory.
264 Paths:
267 /var/run/varnishlog.pid, /var/run/varnishncsa.pid
268 Note: File context can be temporarily modified with the chcon command.
271 If you want to permanently change the file context you need to use the
272 semanage fcontext command. This will modify the SELinux labeling data‐
273 base. You will need to use restorecon to apply the labels.
274
277 semanage fcontext can also be used to manipulate default file context
278 mappings.
279 semanage permissive can also be used to manipulate whether or not a
281 process type is permissive.
282 semanage module can also be used to enable/disable/install/remove pol‐
284 icy modules.
285 semanage boolean can also be used to manipulate the booleans
287 system-config-selinux is a GUI tool available to customize SELinux pol‐
290 icy settings.
