6 haproxy_selinux - Security Enhanced Linux Policy for the haproxy pro‐
7 cesses
8
10 Security-Enhanced Linux secures the haproxy processes via flexible
11 mandatory access control.
12 The haproxy processes execute with the haproxy_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 haproxy_t
20
24 The haproxy_t SELinux type can be entered via the file_type, unla‐
25 beled_t, proc_type, haproxy_exec_t, filesystem_type, mtrr_device_t,
26 sysctl_type file types.
27 The default entrypoint paths for the haproxy_t domain are the follow‐
29 ing:
30 all files on the system, /usr/sbin/haproxy, /dev/cpu/mtrr
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 haproxy policy is very flexible allowing users to setup their haproxy
41 processes in as secure a method as possible.
42 The following process types are defined for haproxy:
44 haproxy_t
46 Note: semanage permissive -a haproxy_t can be used to make the process
48 type haproxy_t permissive. SELinux does not deny access to permissive
49 process types, but the AVC (SELinux denials) messages are still gener‐
50 ated.
51
54 SELinux policy is customizable based on least access required. haproxy
55 policy is extremely flexible and has several booleans that allow you to
56 manipulate the policy and run haproxy with the tightest access possi‐
57 ble.

62 on the allow_daemons_dump_core boolean. Disabled by default.

87 If you want to allow unconfined executables to make their heap memory
91 executable. Doing this is a really bad idea. Probably indicates a
92 badly coded executable, but could indicate an attack. This executable
93 should be reported in bugzilla, you must turn on the allow_execheap
94 boolean. Disabled by default.
95 setsebool -P allow_execheap 1

103 boolean. Enabled by default.
104 setsebool -P allow_execmem 1
106 If you want to allow all unconfined executables to use libraries

114 If you want to allow unconfined executables to make their stack exe‐
118 cutable. This should never, ever be necessary. Probably indicates a
119 badly coded executable, but could indicate an attack. This executable
120 should be reported in bugzilla), you must turn on the allow_execstack
121 boolean. Enabled by default.
122 setsebool -P allow_execstack 1

149 amd64- to use executable memory, you must turn on the clus‐
150 ter_use_execmem boolean. Disabled by default.
151 setsebool -P cluster_use_execmem 1

157 daemons_enable_cluster_mode boolean. Disabled by default.
158 setsebool -P daemons_enable_cluster_mode 1
160 If you want to allow all domains to have the kernel load modules, you
164 must turn on the domain_kernel_load_modules boolean. Disabled by
165 default.
166 setsebool -P domain_kernel_load_modules 1
168 If you want to allow all domains to execute in fips_mode, you must turn
172 on the fips_mode boolean. Enabled by default.
173 setsebool -P fips_mode 1
175 If you want to enable reading of urandom for all domains, you must turn
179 on the global_ssp boolean. Disabled by default.
180 setsebool -P global_ssp 1
182 If you want to enable support for upstart as the init program, you must
186 turn on the init_upstart boolean. Enabled by default.
187 setsebool -P init_upstart 1
189 If you want to allow certain domains to map low memory in the kernel,
193 you must turn on the mmap_low_allowed boolean. Disabled by default.
194 setsebool -P mmap_low_allowed 1
196 If you want to allow confined applications to use nscd shared memory,
200 you must turn on the nscd_use_shm boolean. Enabled by default.
201 setsebool -P nscd_use_shm 1
203 If you want to boolean to determine whether the system permits loading
207 policy, setting enforcing mode, and changing boolean values. Set this
208 to true and you have to reboot to set it back, you must turn on the

223 The SELinux process type haproxy_t can manage files labeled with the
224 following file types. The paths listed are the default paths for these
225 file types. Note the processes UID still need to have DAC permissions.
226 file_type
228 all files on the system
230
233 SELinux requires files to have an extended attribute to define the file
234 type.
235 You can see the context of a file using the -Z option to ls
237 Policy governs the access confined processes have to these files.
239 SELinux haproxy policy is very flexible allowing users to setup their
240 haproxy processes in as secure a method as possible.
241 STANDARD FILE CONTEXT
243 SELinux defines the file context types for the haproxy, if you wanted
245 to store files with these types in a diffent paths, you need to execute
246 the semanage command to sepecify alternate labeling and then use
247 restorecon to put the labels on disk.
248 semanage fcontext -a -t haproxy_var_run_t '/srv/myhaproxy_con‐
250 tent(/.*)?'
251 restorecon -R -v /srv/myhaproxy_content
252 Note: SELinux often uses regular expressions to specify labels that
254 match multiple files.
255 The following file types are defined for haproxy:
257 haproxy_exec_t
261 - Set files with the haproxy_exec_t type, if you want to transition an
263 executable to the haproxy_t domain.
264 haproxy_tmpfs_t
268 - Set files with the haproxy_tmpfs_t type, if you want to store haproxy
270 files on a tmpfs file system.
271 haproxy_var_lib_t
275 - Set files with the haproxy_var_lib_t type, if you want to store the
277 haproxy files under the /var/lib directory.
278 haproxy_var_log_t
282 - Set files with the haproxy_var_log_t type, if you want to treat the
284 data as haproxy var log data, usually stored under the /var/log direc‐
285 tory.
286 haproxy_var_run_t
290 - Set files with the haproxy_var_run_t type, if you want to store the
292 haproxy files under the /run or /var/run directory.
293 Note: File context can be temporarily modified with the chcon command.
297 If you want to permanently change the file context you need to use the
298 semanage fcontext command. This will modify the SELinux labeling data‐
299 base. You will need to use restorecon to apply the labels.
300
303 semanage fcontext can also be used to manipulate default file context
304 mappings.
305 semanage permissive can also be used to manipulate whether or not a
307 process type is permissive.
308 semanage module can also be used to enable/disable/install/remove pol‐
310 icy modules.
311 semanage boolean can also be used to manipulate the booleans
313 system-config-selinux is a GUI tool available to customize SELinux pol‐
316 icy settings.
