NAME

6       pppd_selinux - Security Enhanced Linux Policy for the pppd processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The pppd_t SELinux type can be entered via the pppd_exec_t file type.
24
25       The default entrypoint paths for the pppd_t domain are the following:
26
27       /usr/sbin/pppd, /sbin/ppp-watch, /usr/sbin/ipppd, /sbin/pppoe-server
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       pppd policy is very flexible allowing users to setup  their  pppd  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for pppd:
40
41       pppd_t
42
43       Note:  semanage  permissive  -a  pppd_t can be used to make the process
44       type pppd_t permissive. SELinux does  not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.
47
48

BOOLEANS

50       SELinux policy is customizable based on least  access  required.   pppd
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run pppd with the tightest access possible.
53
54
55

MANAGED FILES

171       The SELinux process type pppd_t can manage files labeled with the  fol‐
172       lowing  file  types.   The paths listed are the default paths for these
173       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

324       SELinux requires files to have an extended attribute to define the file
325       type.
326
327       You can see the context of a file using the -Z option to ls
328
329       Policy  governs  the  access  confined  processes  have to these files.
330       SELinux pppd policy is very flexible allowing users to setup their pppd
331       processes in as secure a method as possible.
332
333       EQUIVALENCE DIRECTORIES
334
335
336       pppd  policy  stores  data  with  multiple different file context types
337       under the /var/run/ppp directory.  If you would like to store the  data
338       in  a different directory you can use the semanage command to create an
339       equivalence mapping.  If you wanted to store this data under  the  /srv
340       dirctory you would execute the following command:
341
342       semanage fcontext -a -e /var/run/ppp /srv/ppp
343       restorecon -R -v /srv/ppp
344
345       STANDARD FILE CONTEXT
346
347       SELinux  defines  the file context types for the pppd, if you wanted to
348       store files with these types in a diffent paths, you  need  to  execute
349       the  semanage  command  to  sepecify  alternate  labeling  and then use
350       restorecon to put the labels on disk.
351
352       semanage fcontext -a -t pppd_var_run_t '/srv/mypppd_content(/.*)?'
353       restorecon -R -v /srv/mypppd_content
354
355       Note: SELinux often uses regular expressions  to  specify  labels  that
356       match multiple files.
357
358       The following file types are defined for pppd:
359
360
361
362       pppd_etc_rw_t
363
364       - Set files with the pppd_etc_rw_t type, if you want to treat the files
365       as pppd etc read/write content.
366
367
368       Paths:
369            /etc/ppp(/.*)?, /etc/ppp/peers(/.*)?, /etc/ppp/resolv.conf
370
371
372       pppd_etc_t
373
374       - Set files with the pppd_etc_t type, if you want to store  pppd  files
375       in the /etc directories.
376
377
378       Paths:
379            /root/.ppprc, /etc/ppp
380
381
382       pppd_exec_t
383
384       -  Set  files  with  the pppd_exec_t type, if you want to transition an
385       executable to the pppd_t domain.
386
387
388       Paths:
389            /usr/sbin/pppd,  /sbin/ppp-watch,  /usr/sbin/ipppd,   /sbin/pppoe-
390            server
391
392
393       pppd_initrc_exec_t
394
395       - Set files with the pppd_initrc_exec_t type, if you want to transition
396       an executable to the pppd_initrc_t domain.
397
398
399       Paths:
400            /etc/ppp/(auth|ip(v6|x)?)-(up|down), /etc/rc.d/init.d/ppp
401
402
403       pppd_lock_t
404
405       - Set files with the pppd_lock_t type, if you want to treat  the  files
406       as pppd lock data, stored under the /var/lock directory
407
408
409
410       pppd_log_t
411
412       -  Set files with the pppd_log_t type, if you want to treat the data as
413       pppd log data, usually stored under the /var/log directory.
414
415
416       Paths:
417            /var/log/ppp/.*, /var/log/ppp-connect-errors.*
418
419
420       pppd_secret_t
421
422       - Set files with the pppd_secret_t type, if you want to treat the files
423       as pppd se secret data.
424
425
426
427       pppd_tmp_t
428
429       -  Set files with the pppd_tmp_t type, if you want to store pppd tempo‐
430       rary files in the /tmp directories.
431
432
433
434       pppd_var_run_t
435
436       - Set files with the pppd_var_run_t type, if you want to store the pppd
437       files under the /run or /var/run directory.
438
439
440       Paths:
441            /var/run/(i)?ppp.*pid[^/]*,                    /var/run/ppp(/.*)?,
442            /var/run/pppd[0-9]*.tdb
443
444
445       Note: File context can be temporarily modified with the chcon  command.
446       If  you want to permanently change the file context you need to use the
447       semanage fcontext command.  This will modify the SELinux labeling data‐
448       base.  You will need to use restorecon to apply the labels.
449
450

COMMANDS

452       semanage  fcontext  can also be used to manipulate default file context
453       mappings.
454
455       semanage permissive can also be used to manipulate  whether  or  not  a
456       process type is permissive.
457
458       semanage  module can also be used to enable/disable/install/remove pol‐
459       icy modules.
460
461       semanage boolean can also be used to manipulate the booleans
462
463
464       system-config-selinux is a GUI tool available to customize SELinux pol‐
465       icy settings.
