6 gpg_web_selinux - Security Enhanced Linux Policy for the gpg_web pro‐
7 cesses
8
10 Security-Enhanced Linux secures the gpg_web processes via flexible
11 mandatory access control.
12 The gpg_web processes execute with the gpg_web_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 gpg_web_t
20
24 The gpg_web_t SELinux type can be entered via the gpg_exec_t file type.
25 The default entrypoint paths for the gpg_web_t domain are the follow‐
27 ing:
28 /usr/lib(64)?/gnupg/.*, /usr/bin/gpg(2)?, /usr/bin/kgpg
30
32 SELinux defines process types (domains) for each process running on the
33 system
34 You can see the context of a process using the -Z option to ps
36 Policy governs the access confined processes have to files. SELinux
38 gpg_web policy is very flexible allowing users to setup their gpg_web
39 processes in as secure a method as possible.
40 The following process types are defined for gpg_web:
42 gpg_web_t
44 Note: semanage permissive -a gpg_web_t can be used to make the process
46 type gpg_web_t permissive. SELinux does not deny access to permissive
47 process types, but the AVC (SELinux denials) messages are still gener‐
48 ated.
49
52 SELinux policy is customizable based on least access required. gpg_web
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run gpg_web with the tightest access possi‐
55 ble.
56 If you want to allow all domains to use other domains file descriptors,
60 you must turn on the allow_domain_fd_use boolean. Enabled by default.
61 setsebool -P allow_domain_fd_use 1
63 If you want to allow sysadm to debug or ptrace all processes, you must
67 turn on the allow_ptrace boolean. Disabled by default.
68 setsebool -P allow_ptrace 1
70 If you want to allow all domains to have the kernel load modules, you
74 must turn on the domain_kernel_load_modules boolean. Disabled by
75 default.
76 setsebool -P domain_kernel_load_modules 1
78 If you want to allow all domains to execute in fips_mode, you must turn
82 on the fips_mode boolean. Enabled by default.
83 setsebool -P fips_mode 1
85 If you want to enable reading of urandom for all domains, you must turn
89 on the global_ssp boolean. Disabled by default.
90 setsebool -P global_ssp 1
92 If you want to allow httpd cgi support, you must turn on the
96 httpd_enable_cgi boolean. Enabled by default.
97 setsebool -P httpd_enable_cgi 1
99 If you want to allow httpd to run gpg in gpg-web domain, you must turn
103 on the httpd_use_gpg boolean. Disabled by default.
104 setsebool -P httpd_use_gpg 1
106
110 The SELinux process type gpg_web_t can manage files labeled with the
111 following file types. The paths listed are the default paths for these
112 file types. Note the processes UID still need to have DAC permissions.

173 If you want to share files with multiple domains (Apache, FTP, rsync,
174 Samba), you can set a file context of public_content_t and public_con‐
175 tent_rw_t. These context allow any of the above domains to read the
176 content. If you want a particular domain to write to the public_con‐
177 tent_rw_t domain, you must set the appropriate boolean.
178 Allow gpg_web servers to read the /var/gpg_web directory by adding the
180 public_content_t file type to the directory and by restoring the file
181 type.
182 semanage fcontext -a -t public_content_t "/var/gpg_web(/.*)?"
184 restorecon -F -R -v /var/gpg_web
185 Allow gpg_web servers to read and write /var/gpg_web/incoming by adding
187 the public_content_rw_t type to the directory and by restoring the file
188 type. You also need to turn on the gpg_web_anon_write boolean.
189 semanage fcontext -a -t public_content_rw_t "/var/gpg_web/incom‐
191 ing(/.*)?"
192 restorecon -F -R -v /var/gpg_web/incoming
193 setsebool -P gpg_web_anon_write 1
194 If you want to allow gpg web domain to modify public files used for
197 public file transfer services., you must turn on the gpg_web_anon_write
198 boolean.
199 setsebool -P gpg_web_anon_write 1
201
204 semanage fcontext can also be used to manipulate default file context
205 mappings.
206 semanage permissive can also be used to manipulate whether or not a
208 process type is permissive.
209 semanage module can also be used to enable/disable/install/remove pol‐
211 icy modules.
212 semanage boolean can also be used to manipulate the booleans
214 system-config-selinux is a GUI tool available to customize SELinux pol‐
217 icy settings.
