6 gitosis_selinux - Security Enhanced Linux Policy for the gitosis pro‐
7 cesses
8
10 Security-Enhanced Linux secures the gitosis processes via flexible
11 mandatory access control.
12 The gitosis processes execute with the gitosis_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 gitosis_t
20
24 The gitosis_t SELinux type can be entered via the gitosis_exec_t file
25 type.
26 The default entrypoint paths for the gitosis_t domain are the follow‐
28 ing:
29 /usr/bin/gitosis-serve, /usr/bin/gl-auth-command
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 gitosis policy is very flexible allowing users to setup their gitosis
40 processes in as secure a method as possible.
41 The following process types are defined for gitosis:
43 gitosis_t
45 Note: semanage permissive -a gitosis_t can be used to make the process
47 type gitosis_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. gitosis
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run gitosis with the tightest access possi‐
56 ble.
57 If you want to determine whether Gitosis can send mail, you must turn
61 on the gitosis_can_sendmail boolean. Disabled by default.
62 setsebool -P gitosis_can_sendmail 1
64 If you want to deny any process from ptracing or debugging any other
68 processes, you must turn on the deny_ptrace boolean. Enabled by
69 default.
70 setsebool -P deny_ptrace 1
72 If you want to allow any process to mmap any file on system with
76 attribute file_type, you must turn on the domain_can_mmap_files bool‐
77 ean. Enabled by default.
78 setsebool -P domain_can_mmap_files 1
80 If you want to allow all domains write to kmsg_device, while kernel is
84 executed with systemd.log_target=kmsg parameter, you must turn on the
85 domain_can_write_kmsg boolean. Disabled by default.
86 setsebool -P domain_can_write_kmsg 1
88 If you want to allow all domains to use other domains file descriptors,
92 you must turn on the domain_fd_use boolean. Enabled by default.
93 setsebool -P domain_fd_use 1
95 If you want to allow all domains to have the kernel load modules, you
99 must turn on the domain_kernel_load_modules boolean. Disabled by
100 default.
101 setsebool -P domain_kernel_load_modules 1
103 If you want to allow all domains to execute in fips_mode, you must turn
107 on the fips_mode boolean. Enabled by default.
108 setsebool -P fips_mode 1
110 If you want to enable reading of urandom for all domains, you must turn
114 on the global_ssp boolean. Disabled by default.
115 setsebool -P global_ssp 1

121 The SELinux process type gitosis_t can manage files labeled with the
122 following file types. The paths listed are the default paths for these
123 file types. Note the processes UID still need to have DAC permissions.
124 gitosis_var_lib_t
126 /srv/lib/gitosis(/.*)?
128 /var/lib/gitosis(/.*)?
129 /var/lib/gitolite(3)?(/.*)?
130
133 SELinux requires files to have an extended attribute to define the file
134 type.
135 You can see the context of a file using the -Z option to ls
137 Policy governs the access confined processes have to these files.
139 SELinux gitosis policy is very flexible allowing users to setup their
140 gitosis processes in as secure a method as possible.
141 STANDARD FILE CONTEXT
143 SELinux defines the file context types for the gitosis, if you wanted
145 to store files with these types in a diffent paths, you need to execute
146 the semanage command to sepecify alternate labeling and then use
147 restorecon to put the labels on disk.
148 semanage fcontext -a -t gitosis_var_lib_t '/srv/mygitosis_con‐
150 tent(/.*)?'
151 restorecon -R -v /srv/mygitosis_content
152 Note: SELinux often uses regular expressions to specify labels that
154 match multiple files.
155 The following file types are defined for gitosis:
157 gitosis_exec_t
161 - Set files with the gitosis_exec_t type, if you want to transition an
163 executable to the gitosis_t domain.
164 Paths:
167 /usr/bin/gitosis-serve, /usr/bin/gl-auth-command
168 gitosis_var_lib_t
171 - Set files with the gitosis_var_lib_t type, if you want to store the
173 gitosis files under the /var/lib directory.
174 Paths:
177 /srv/lib/gitosis(/.*)?, /var/lib/gitosis(/.*)?, /var/lib/gito‐
178 lite(3)?(/.*)?
179 Note: File context can be temporarily modified with the chcon command.
182 If you want to permanently change the file context you need to use the
183 semanage fcontext command. This will modify the SELinux labeling data‐
184 base. You will need to use restorecon to apply the labels.
185
188 semanage fcontext can also be used to manipulate default file context
189 mappings.
190 semanage permissive can also be used to manipulate whether or not a
192 process type is permissive.
193 semanage module can also be used to enable/disable/install/remove pol‐
195 icy modules.
196 semanage boolean can also be used to manipulate the booleans
198 system-config-selinux is a GUI tool available to customize SELinux pol‐
201 icy settings.
