6 httpd_user_script_selinux - Security Enhanced Linux Policy for the
7 httpd_user_script processes
8
10 Security-Enhanced Linux secures the httpd_user_script processes via
11 flexible mandatory access control.
12 The httpd_user_script processes execute with the httpd_user_script_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep httpd_user_script_t
20
24 The httpd_user_script_t SELinux type can be entered via the
25 httpd_user_script_exec_t, shell_exec_t, httpd_user_script_exec_t,
26 httpdcontent file types.
27 The default entrypoint paths for the httpd_user_script_t domain are the
29 following:
30 /bin/d?ash, /bin/zsh.*, /bin/ksh.*, /bin/sash, /bin/tcsh, /bin/yash,
32 /bin/mksh, /bin/fish, /bin/bash, /bin/bash2, /usr/bin/fish, /sbin/nolo‐
33 gin, /usr/sbin/sesh, /usr/sbin/smrsh, /usr/bin/scponly,
34 /usr/libexec/sesh, /usr/sbin/scponlyc, /usr/bin/git-shell,
35 /usr/libexec/git-core/git-shell

38 SELinux defines process types (domains) for each process running on the
39 system
40 You can see the context of a process using the -Z option to ps
42 Policy governs the access confined processes have to files. SELinux
44 httpd_user_script policy is very flexible allowing users to setup their
45 httpd_user_script processes in as secure a method as possible.
46 The following process types are defined for httpd_user_script:
48 httpd_user_script_t
50 Note: semanage permissive -a httpd_user_script_t can be used to make
52 the process type httpd_user_script_t permissive. SELinux does not deny
53 access to permissive process types, but the AVC (SELinux denials) mes‐
54 sages are still generated.
55
58 SELinux policy is customizable based on least access required.
59 httpd_user_script policy is extremely flexible and has several booleans
60 that allow you to manipulate the policy and run httpd_user_script with
61 the tightest access possible.
62 If you want to allow all domains to use other domains file descriptors,
66 you must turn on the allow_domain_fd_use boolean. Enabled by default.
67 setsebool -P allow_domain_fd_use 1
69 If you want to allow sysadm to debug or ptrace all processes, you must
73 turn on the allow_ptrace boolean. Disabled by default.
74 setsebool -P allow_ptrace 1
76 If you want to allow system to run with NIS, you must turn on the
80 allow_ypbind boolean. Disabled by default.
81 setsebool -P allow_ypbind 1
83 If you want to allow all domains to have the kernel load modules, you
87 must turn on the domain_kernel_load_modules boolean. Disabled by
88 default.
89 setsebool -P domain_kernel_load_modules 1
91 If you want to allow all domains to execute in fips_mode, you must turn
95 on the fips_mode boolean. Enabled by default.
96 setsebool -P fips_mode 1
98 If you want to enable reading of urandom for all domains, you must turn
102 on the global_ssp boolean. Disabled by default.
103 setsebool -P global_ssp 1
105 If you want to allow httpd cgi support, you must turn on the
109 httpd_enable_cgi boolean. Enabled by default.
110 setsebool -P httpd_enable_cgi 1
112 If you want to allow httpd to read home directories, you must turn on
116 the httpd_enable_homedirs boolean. Disabled by default.
117 setsebool -P httpd_enable_homedirs 1
119 If you want to allow httpd to read user content, you must turn on the
123 httpd_read_user_content boolean. Disabled by default.
124 setsebool -P httpd_read_user_content 1
126 If you want to unify HTTPD to communicate with the terminal. Needed for
130 entering the passphrase for certificates at the terminal, you must turn
131 on the httpd_tty_comm boolean. Disabled by default.
132 setsebool -P httpd_tty_comm 1
134 If you want to unify HTTPD handling of all content files, you must turn
138 on the httpd_unified boolean. Disabled by default.
139 setsebool -P httpd_unified 1
141 If you want to allow unprivileged users to execute DDL statement, you
145 must turn on the sepgsql_enable_users_ddl boolean. Enabled by default.
146 setsebool -P sepgsql_enable_users_ddl 1
148
152 The SELinux process type httpd_user_script_t can manage files labeled
153 with the following file types. The paths listed are the default paths
154 for these file types. Note the processes UID still need to have DAC
155 permissions.
156 httpd_user_content_t
158 /home/[^/]*/((www)|(web)|(public_html))(/.+)?
160 /home/staff/((www)|(web)|(public_html))(/.+)?
161 httpd_user_ra_content_t
163 httpd_user_rw_content_t
166 initrc_tmp_t
169 mnt_t
172 /mnt(/[^/]*)
174 /mnt(/[^/]*)?
175 /rhev(/[^/]*)?
176 /media(/[^/]*)
177 /media(/[^/]*)?
178 /etc/rhgb(/.*)?
179 /media/.hal-.*
180 /net
181 /afs
182 /rhev
183 /misc
184 tmp_t
186 /tmp
188 /usr/tmp
189 /var/tmp
190 /tmp-inst
191 /var/tmp-inst
192 /var/tmp/vi.recover
193
196 semanage fcontext can also be used to manipulate default file context
197 mappings.
198 semanage permissive can also be used to manipulate whether or not a
200 process type is permissive.
201 semanage module can also be used to enable/disable/install/remove pol‐
203 icy modules.
204 semanage boolean can also be used to manipulate the booleans
206 system-config-selinux is a GUI tool available to customize SELinux pol‐
209 icy settings.
