6 httpd_w3c_validator_script_selinux - Security Enhanced Linux Policy for
7 the httpd_w3c_validator_script processes
8
10 Security-Enhanced Linux secures the httpd_w3c_validator_script pro‐
11 cesses via flexible mandatory access control.
12 The httpd_w3c_validator_script processes execute with the
14 httpd_w3c_validator_script_t SELinux type. You can check if you have
15 these processes running by executing the ps command with the -Z quali‐
16 fier.
17 For example:
19 ps -eZ | grep httpd_w3c_validator_script_t
21
25 The httpd_w3c_validator_script_t SELinux type can be entered via the
26 httpd_w3c_validator_script_exec_t, shell_exec_t, httpd_w3c_valida‐
27 tor_script_exec_t file types.
28 The default entrypoint paths for the httpd_w3c_validator_script_t
30 domain are the following:
31 /usr/share/w3c-markup-validator/cgi-bin(/.*)?, /usr/lib/cgi-bin/check,
33 /bin/d?ash, /bin/zsh.*, /bin/ksh.*, /bin/sash, /bin/tcsh, /bin/yash,
34 /bin/mksh, /bin/fish, /bin/bash, /bin/bash2, /usr/bin/fish, /sbin/nolo‐
35 gin, /usr/sbin/sesh, /usr/sbin/smrsh, /usr/bin/scponly,
36 /usr/libexec/sesh, /usr/sbin/scponlyc, /usr/bin/git-shell,
37 /usr/libexec/git-core/git-shell, /usr/share/w3c-markup-validator/cgi-
38 bin(/.*)?, /usr/lib/cgi-bin/check

41 SELinux defines process types (domains) for each process running on the
42 system
43 You can see the context of a process using the -Z option to ps
45 Policy governs the access confined processes have to files. SELinux
47 httpd_w3c_validator_script policy is very flexible allowing users to
48 setup their httpd_w3c_validator_script processes in as secure a method
49 as possible.
50 The following process types are defined for httpd_w3c_validator_script:
52 httpd_w3c_validator_script_t
54 Note: semanage permissive -a httpd_w3c_validator_script_t can be used
56 to make the process type httpd_w3c_validator_script_t permissive.
57 SELinux does not deny access to permissive process types, but the AVC
58 (SELinux denials) messages are still generated.
59
62 SELinux policy is customizable based on least access required.
63 httpd_w3c_validator_script policy is extremely flexible and has several
64 booleans that allow you to manipulate the policy and run httpd_w3c_val‐
65 idator_script with the tightest access possible.
66 If you want to allow all domains to use other domains file descriptors,
70 you must turn on the allow_domain_fd_use boolean. Enabled by default.
71 setsebool -P allow_domain_fd_use 1
73 If you want to allow sysadm to debug or ptrace all processes, you must
77 turn on the allow_ptrace boolean. Disabled by default.
78 setsebool -P allow_ptrace 1
80 If you want to allow system to run with NIS, you must turn on the
84 allow_ypbind boolean. Disabled by default.
85 setsebool -P allow_ypbind 1
87 If you want to allow all domains to have the kernel load modules, you
91 must turn on the domain_kernel_load_modules boolean. Disabled by
92 default.
93 setsebool -P domain_kernel_load_modules 1
95 If you want to allow all domains to execute in fips_mode, you must turn
99 on the fips_mode boolean. Enabled by default.
100 setsebool -P fips_mode 1
102 If you want to enable reading of urandom for all domains, you must turn
106 on the global_ssp boolean. Disabled by default.
107 setsebool -P global_ssp 1
109 If you want to allow httpd cgi support, you must turn on the
113 httpd_enable_cgi boolean. Enabled by default.
114 setsebool -P httpd_enable_cgi 1
116 If you want to allow unprivileged users to execute DDL statement, you
120 must turn on the sepgsql_enable_users_ddl boolean. Enabled by default.
121 setsebool -P sepgsql_enable_users_ddl 1
123
127 The SELinux process type httpd_w3c_validator_script_t can manage files
128 labeled with the following file types. The paths listed are the
129 default paths for these file types. Note the processes UID still need
130 to have DAC permissions.
131 httpd_w3c_validator_rw_content_t
133 httpd_w3c_validator_tmp_t
136 initrc_tmp_t
139 mnt_t
142 /mnt(/[^/]*)
144 /mnt(/[^/]*)?
145 /rhev(/[^/]*)?
146 /media(/[^/]*)
147 /media(/[^/]*)?
148 /etc/rhgb(/.*)?
149 /media/.hal-.*
150 /net
151 /afs
152 /rhev
153 /misc
154 tmp_t
156 /tmp

159 /var/tmp
160 /tmp-inst
161 /var/tmp-inst
162 /var/tmp/vi.recover

166 SELinux requires files to have an extended attribute to define the file
167 type.
168 You can see the context of a file using the -Z option to ls
170 Policy governs the access confined processes have to these files.
172 SELinux httpd_w3c_validator_script policy is very flexible allowing
173 users to setup their httpd_w3c_validator_script processes in as secure
174 a method as possible.
175 The following file types are defined for httpd_w3c_validator_script:
177 httpd_w3c_validator_script_exec_t
181 - Set files with the httpd_w3c_validator_script_exec_t type, if you
183 want to transition an executable to the httpd_w3c_validator_script_t
184 domain.
185 Paths:
188 /usr/share/w3c-markup-validator/cgi-bin(/.*)?, /usr/lib/cgi-
189 bin/check
190 Note: File context can be temporarily modified with the chcon command.
193 If you want to permanently change the file context you need to use the
194 semanage fcontext command. This will modify the SELinux labeling data‐
195 base. You will need to use restorecon to apply the labels.
196
199 semanage fcontext can also be used to manipulate default file context
200 mappings.
201 semanage permissive can also be used to manipulate whether or not a
203 process type is permissive.
204 semanage module can also be used to enable/disable/install/remove pol‐
206 icy modules.
207 semanage boolean can also be used to manipulate the booleans
209 system-config-selinux is a GUI tool available to customize SELinux pol‐
212 icy settings.
