NAME

6       postgresql_selinux  - Security Enhanced Linux Policy for the postgresql
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the postgresql processes  via  flexible
11       mandatory access control.
12
13       The  postgresql  processes  execute with the postgresql_t SELinux type.
14       You can check if you have these processes running by executing  the  ps
15       command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep postgresql_t
20
21
22

ENTRYPOINTS

24       The  postgresql_t SELinux type can be entered via the postgresql_exec_t
25       file type.
26
27       The default entrypoint paths for the postgresql_t domain are  the  fol‐
28       lowing:
29
30       /usr/bin/(se)?postgres,    /usr/bin/initdb(.sepgsql)?,   /usr/lib/post‐
31       gresql/bin/.*,      /usr/bin/pg_ctl,       /usr/libexec/postgresql-ctl,
32       /usr/bin/postgresql-check-db-dir,
33       /usr/lib/pgsql/test/regress/pg_regress
34

PROCESS TYPES

36       SELinux defines process types (domains) for each process running on the
37       system
38
39       You can see the context of a process using the -Z option to ps
40
41       Policy  governs  the  access confined processes have to files.  SELinux
42       postgresql policy is very flexible allowing users to setup their  post‐
43       gresql processes in as secure a method as possible.
44
45       The following process types are defined for postgresql:
46
47       postgresql_t
48
49       Note:  semanage  permissive  -a  postgresql_t  can  be used to make the
50       process type postgresql_t permissive. SELinux does not deny  access  to
51       permissive  process  types,  but the AVC (SELinux denials) messages are
52       still generated.
53
54

BOOLEANS

56       SELinux policy is customizable based on least access  required.   post‐
57       gresql policy is extremely flexible and has several booleans that allow
58       you to manipulate the policy  and  run  postgresql  with  the  tightest
59       access possible.
60
61
62
63       If  you want to allow postgresql to use ssh and rsync for point-in-time
64       recovery, you must turn on the postgresql_can_rsync  boolean.  Disabled
65       by default.
66
67       setsebool -P postgresql_can_rsync 1
68
69
70
71       If  you  want  to  allow transmit client label to foreign database, you
72       must turn on the postgresql_selinux_transmit_client_label boolean. Dis‐
73       abled by default.
74
75       setsebool -P postgresql_selinux_transmit_client_label 1
76
77
78
79       If you want to deny user domains applications to map a memory region as
80       both executable and writable, this  is  dangerous  and  the  executable
81       should be reported in bugzilla, you must turn on the deny_execmem bool‐
82       ean. Enabled by default.
83
84       setsebool -P deny_execmem 1
85
86
87
88       If you want to determine whether exim can  connect  to  databases,  you
89       must turn on the exim_can_connect_db boolean. Disabled by default.
90
91       setsebool -P exim_can_connect_db 1
92
93
94
95       If you want to allow all domains to execute in fips_mode, you must turn
96       on the fips_mode boolean. Enabled by default.
97
98       setsebool -P fips_mode 1
99
100
101
102       If you want to determine whether ftpd can connect to databases over the
103       TCP  network, you must turn on the ftpd_connect_db boolean. Disabled by
104       default.
105
106       setsebool -P ftpd_connect_db 1
107
108
109
110       If you want to allow HTTPD scripts and modules to connect to  databases
111       over  the  network,  you  must turn on the httpd_can_network_connect_db
112       boolean. Disabled by default.
113
114       setsebool -P httpd_can_network_connect_db 1
115
116
117
118       If you want to allow confined applications to run  with  kerberos,  you
119       must turn on the kerberos_enabled boolean. Disabled by default.
120
121       setsebool -P kerberos_enabled 1
122
123
124
125       If  you  want  to  allow  system  to run with NIS, you must turn on the
126       nis_enabled boolean. Disabled by default.
127
128       setsebool -P nis_enabled 1
129
130
131
132       If you want to allow PowerDNS to connect to databases over the network,
133       you  must  turn on the pdns_can_network_connect_db boolean. Disabled by
134       default.
135
136       setsebool -P pdns_can_network_connect_db 1
137
138
139

PORT TYPES

141       SELinux defines port types to represent TCP and UDP ports.
142
143       You can see the types associated with a port  by  using  the  following
144       command:
145
146       semanage port -l
147
148
149       Policy  governs  the  access  confined  processes  have to these ports.
150       SELinux postgresql policy is very  flexible  allowing  users  to  setup
151       their postgresql processes in as secure a method as possible.
152
153       The following port types are defined for postgresql:
154
155
156       postgresql_port_t
157
158
159
160       Default Defined Ports:
161                 tcp 5432,9898
162

MANAGED FILES

164       The SELinux process type postgresql_t can manage files labeled with the
165       following file types.  The paths listed are the default paths for these
166       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

252       SELinux requires files to have an extended attribute to define the file
253       type.
254
255       You can see the context of a file using the -Z option to ls
256
257       Policy governs the access  confined  processes  have  to  these  files.
258       SELinux  postgresql  policy  is  very  flexible allowing users to setup
259       their postgresql processes in as secure a method as possible.
260
261       EQUIVALENCE DIRECTORIES
262
263
264       postgresql policy stores data  with  multiple  different  file  context
265       types  under  the /var/lib/pgsql directory.  If you would like to store
266       the data in a different directory you can use the semanage  command  to
267       create  an equivalence mapping.  If you wanted to store this data under
268       the /srv directory you would execute the following command:
269
270       semanage fcontext -a -e /var/lib/pgsql /srv/pgsql
271       restorecon -R -v /srv/pgsql
272
273       postgresql policy stores data  with  multiple  different  file  context
274       types under the /var/lib/sepgsql directory.  If you would like to store
275       the data in a different directory you can use the semanage  command  to
276       create  an equivalence mapping.  If you wanted to store this data under
277       the /srv directory you would execute the following command:
278
279       semanage fcontext -a -e /var/lib/sepgsql /srv/sepgsql
280       restorecon -R -v /srv/sepgsql
281
282       STANDARD FILE CONTEXT
283
284       SELinux defines the file context  types  for  the  postgresql,  if  you
285       wanted  to store files with these types in a diffent paths, you need to
286       execute the semanage command to sepecify alternate  labeling  and  then
287       use restorecon to put the labels on disk.
288
289       semanage  fcontext  -a  -t postgresql_var_run_t '/srv/mypostgresql_con‐
290       tent(/.*)?'
291       restorecon -R -v /srv/mypostgresql_content
292
293       Note: SELinux often uses regular expressions  to  specify  labels  that
294       match multiple files.
295
296       The following file types are defined for postgresql:
297
298
299
300       postgresql_db_t
301
302       -  Set  files  with  the postgresql_db_t type, if you want to treat the
303       files as postgresql database content.

307            /var/lib/pgsql(/.*)?,    /var/lib/sepgsql(/.*)?,    /var/lib/post‐
308            gres(ql)?(/.*)?,                     /usr/share/jonas/pgsql(/.*)?,
309            /usr/lib/pgsql/test/regress(/.*)?
310
311
312       postgresql_etc_t

319            /etc/postgresql(/.*)?, /etc/sysconfig/pgsql(/.*)?
320
321
322       postgresql_exec_t
323
324       -  Set files with the postgresql_exec_t type, if you want to transition
325       an executable to the postgresql_t domain.
326
327
328       Paths:
329            /usr/bin/(se)?postgres, /usr/bin/initdb(.sepgsql)?, /usr/lib/post‐
330            gresql/bin/.*,    /usr/bin/pg_ctl,    /usr/libexec/postgresql-ctl,
331            /usr/bin/postgresql-check-db-dir,
332            /usr/lib/pgsql/test/regress/pg_regress
333
334
335       postgresql_initrc_exec_t
336
337       -  Set  files  with  the  postgresql_initrc_exec_t type, if you want to
338       transition an executable to the postgresql_initrc_t domain.
339
340
341
342       postgresql_lock_t
343
344       - Set files with the postgresql_lock_t type, if you want to  treat  the
345       files as postgresql lock data, stored under the /var/lock directory
346
347
348
349       postgresql_log_t
350
351       -  Set  files  with the postgresql_log_t type, if you want to treat the
352       data as postgresql log data, usually stored under the  /var/log  direc‐
353       tory.
354
355
356       Paths:
357            /var/lib/pgsql/.*.log,   /var/log/rhdb/rhdb(/.*)?,  /var/log/post‐
358            gresql(/.*)?,     /var/log/postgres.log.*,     /var/lib/pgsql/log‐
359            file(/.*)?,     /var/lib/pgsql/data/log(/.*)?,    /var/log/sepost‐
360            gresql.log.*,                    /var/lib/pgsql/data/pg_log(/.*)?,
361            /var/lib/sepgsql/pgstartup.log
362
363
364       postgresql_tmp_t
365
366       -  Set files with the postgresql_tmp_t type, if you want to store post‐
367       gresql temporary files in the /tmp directories.
368
369
370
371       postgresql_unit_file_t
372
373       - Set files with the postgresql_unit_file_t type, if you want to  treat
374       the files as postgresql unit content.
375
376
377
378       postgresql_var_run_t
379
380       -  Set  files  with the postgresql_var_run_t type, if you want to store
381       the postgresql files under the /run or /var/run directory.
382
383
384
385       Note: File context can be temporarily modified with the chcon  command.
386       If  you want to permanently change the file context you need to use the
387       semanage fcontext command.  This will modify the SELinux labeling data‐
388       base.  You will need to use restorecon to apply the labels.
389
390

COMMANDS

392       semanage  fcontext  can also be used to manipulate default file context
393       mappings.
394
395       semanage permissive can also be used to manipulate  whether  or  not  a
396       process type is permissive.
397
398       semanage  module can also be used to enable/disable/install/remove pol‐
399       icy modules.
400
401       semanage port can also be used to manipulate the port definitions
402
403       semanage boolean can also be used to manipulate the booleans
404
405
406       system-config-selinux is a GUI tool available to customize SELinux pol‐
407       icy settings.
