NAME

6       git_script_selinux  - Security Enhanced Linux Policy for the git_script
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the git_script processes  via  flexible
11       mandatory access control.
12
13       The  git_script  processes  execute with the git_script_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 git_script_t
20
21
22

ENTRYPOINTS

24       The  git_script_t  SELinux  type  can  be entered via the shell_exec_t,
25       git_script_exec_t, git_script_exec_t file types.
26
27       The default entrypoint paths for the git_script_t domain are  the  fol‐
28       lowing:
29
30       /bin/d?ash,  /bin/zsh.*,  /bin/ksh.*,  /usr/bin/d?ash,  /usr/bin/ksh.*,
31       /usr/bin/zsh.*, /bin/esh, /bin/mksh, /bin/sash,  /bin/tcsh,  /bin/yash,
32       /bin/bash,    /bin/fish,   /bin/bash2,   /usr/bin/esh,   /usr/bin/sash,
33       /usr/bin/tcsh,     /usr/bin/yash,     /usr/bin/mksh,     /usr/bin/fish,
34       /usr/bin/bash,     /sbin/nologin,    /usr/sbin/sesh,    /usr/bin/bash2,
35       /usr/sbin/smrsh,          /usr/bin/scponly,          /usr/sbin/nologin,

37       /usr/libexec/sudo/sesh, /usr/bin/cockpit-bridge,  /usr/libexec/cockpit-
38       agent,      /usr/libexec/git-core/git-shell,     /var/www/cgi-bin/cgit,
39       /var/www/git/gitweb.cgi,            /var/www/gitweb-caching/gitweb.cgi,
40       /var/www/cgi-bin/cgit,     /var/www/git/gitweb.cgi,    /var/www/gitweb-
41       caching/gitweb.cgi

PROCESS TYPES

44       SELinux defines process types (domains) for each process running on the
45       system
46
47       You can see the context of a process using the -Z option to ps
48
49       Policy  governs  the  access confined processes have to files.  SELinux
50       git_script policy is  very  flexible  allowing  users  to  setup  their
51       git_script processes in as secure a method as possible.
52
53       The following process types are defined for git_script:
54
55       git_script_t
56
57       Note:  semanage  permissive  -a  git_script_t  can  be used to make the
58       process type git_script_t permissive. SELinux does not deny  access  to
59       permissive  process  types,  but the AVC (SELinux denials) messages are
60       still generated.
61
62

BOOLEANS

64       SELinux  policy  is  customizable  based  on  least  access   required.
65       git_script  policy  is extremely flexible and has several booleans that
66       allow you to manipulate the policy and run git_script with the tightest
67       access possible.

MANAGED FILES

205       The SELinux process type git_script_t can manage files labeled with the
206       following file types.  The paths listed are the default paths for these
207       file types.  Note the processes UID still need to have DAC permissions.
208
209       git_rw_content_t
210
211            /var/cache/cgit(/.*)?
212            /var/cache/gitweb-caching(/.*)?
213
214       git_script_tmp_t
215
216
217

FILE CONTEXTS

219       SELinux requires files to have an extended attribute to define the file
220       type.
221
222       You can see the context of a file using the -Z option to ls
223
224       Policy  governs  the  access  confined  processes  have to these files.
225       SELinux git_script policy is very  flexible  allowing  users  to  setup
226       their git_script processes in as secure a method as possible.
227
228       STANDARD FILE CONTEXT
229
230       SELinux  defines  the  file  context  types  for the git_script, if you
231       wanted to store files with these types in a diffent paths, you need  to
232       execute  the  semanage  command to sepecify alternate labeling and then
233       use restorecon to put the labels on disk.
234
235       semanage  fcontext  -a  -t   git_script_tmp_t   '/srv/mygit_script_con‐
236       tent(/.*)?'
237       restorecon -R -v /srv/mygit_script_content
238
239       Note:  SELinux  often  uses  regular expressions to specify labels that
240       match multiple files.
241
242       The following file types are defined for git_script:
243
244
245
246       git_script_exec_t
247
248       - Set files with the git_script_exec_t type, if you want to  transition
249       an executable to the git_script_t domain.
250
251
252       Paths:
253            /var/www/cgi-bin/cgit,  /var/www/git/gitweb.cgi,  /var/www/gitweb-
254            caching/gitweb.cgi
255
256
257       git_script_tmp_t
258
259       - Set files with the git_script_tmp_t type, if you want  to  store  git
260       script temporary files in the /tmp directories.
261
262
263
264       Note:  File context can be temporarily modified with the chcon command.
265       If you want to permanently change the file context you need to use  the
266       semanage fcontext command.  This will modify the SELinux labeling data‐
267       base.  You will need to use restorecon to apply the labels.
268
269

COMMANDS

271       semanage fcontext can also be used to manipulate default  file  context
272       mappings.
273
274       semanage  permissive  can  also  be used to manipulate whether or not a
275       process type is permissive.
276
277       semanage module can also be used to enable/disable/install/remove  pol‐
278       icy modules.
279
280       semanage boolean can also be used to manipulate the booleans
281
282
283       system-config-selinux is a GUI tool available to customize SELinux pol‐
284       icy settings.
