6 httpd_squid_script_selinux - Security Enhanced Linux Policy for the
7 httpd_squid_script processes
8
10 Security-Enhanced Linux secures the httpd_squid_script processes via
11 flexible mandatory access control.
12 The httpd_squid_script processes execute with the httpd_squid_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_squid_script_t
20
24 The httpd_squid_script_t SELinux type can be entered via the
25 shell_exec_t, httpd_squid_script_exec_t, httpd_squid_script_exec_t file
26 types.
27 The default entrypoint paths for the httpd_squid_script_t domain are
29 the 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, /usr/lib/squid/cachemgr.cgi,
36 /usr/lib64/squid/cachemgr.cgi, /usr/lib/squid/cachemgr.cgi,
37 /usr/lib64/squid/cachemgr.cgi

40 SELinux defines process types (domains) for each process running on the
41 system
42 You can see the context of a process using the -Z option to ps
44 Policy governs the access confined processes have to files. SELinux
46 httpd_squid_script policy is very flexible allowing users to setup
47 their httpd_squid_script processes in as secure a method as possible.
48 The following process types are defined for httpd_squid_script:
50 httpd_squid_script_t
52 Note: semanage permissive -a httpd_squid_script_t can be used to make
54 the process type httpd_squid_script_t permissive. SELinux does not deny
55 access to permissive process types, but the AVC (SELinux denials) mes‐
56 sages are still generated.
57
60 SELinux policy is customizable based on least access required.
61 httpd_squid_script policy is extremely flexible and has several bool‐
62 eans that allow you to manipulate the policy and run httpd_squid_script
63 with the tightest access possible.
64 If you want to allow all domains to use other domains file descriptors,
68 you must turn on the allow_domain_fd_use boolean. Enabled by default.
69 setsebool -P allow_domain_fd_use 1
71 If you want to allow sysadm to debug or ptrace all processes, you must
75 turn on the allow_ptrace boolean. Disabled by default.
76 setsebool -P allow_ptrace 1
78 If you want to allow system to run with NIS, you must turn on the
82 allow_ypbind boolean. Disabled by default.
83 setsebool -P allow_ypbind 1
85 If you want to allow all domains to have the kernel load modules, you
89 must turn on the domain_kernel_load_modules boolean. Disabled by
90 default.
91 setsebool -P domain_kernel_load_modules 1
93 If you want to allow all domains to execute in fips_mode, you must turn
97 on the fips_mode boolean. Enabled by default.
98 setsebool -P fips_mode 1
100 If you want to enable reading of urandom for all domains, you must turn
104 on the global_ssp boolean. Disabled by default.
105 setsebool -P global_ssp 1
107 If you want to allow httpd cgi support, you must turn on the
111 httpd_enable_cgi boolean. Enabled by default.
112 setsebool -P httpd_enable_cgi 1
114 If you want to allow unprivileged users to execute DDL statement, you
118 must turn on the sepgsql_enable_users_ddl boolean. Enabled by default.
119 setsebool -P sepgsql_enable_users_ddl 1
121
125 The SELinux process type httpd_squid_script_t can manage files labeled
126 with the following file types. The paths listed are the default paths
127 for these file types. Note the processes UID still need to have DAC
128 permissions.
129 httpd_squid_rw_content_t
131 initrc_tmp_t
134 mnt_t
137 /mnt(/[^/]*)
139 /mnt(/[^/]*)?
140 /rhev(/[^/]*)?
141 /media(/[^/]*)
142 /media(/[^/]*)?
143 /etc/rhgb(/.*)?
144 /media/.hal-.*
145 /net
146 /afs
147 /rhev
148 /misc
149 tmp_t
151 /tmp
153 /usr/tmp
154 /var/tmp
155 /tmp-inst
156 /var/tmp-inst
157 /var/tmp/vi.recover

161 SELinux requires files to have an extended attribute to define the file
162 type.
163 You can see the context of a file using the -Z option to ls
165 Policy governs the access confined processes have to these files.
167 SELinux httpd_squid_script policy is very flexible allowing users to
168 setup their httpd_squid_script processes in as secure a method as pos‐
169 sible.
170 The following file types are defined for httpd_squid_script:
172 httpd_squid_script_exec_t
176 - Set files with the httpd_squid_script_exec_t type, if you want to
178 transition an executable to the httpd_squid_script_t domain.
179 Paths:
182 /usr/lib/squid/cachemgr.cgi, /usr/lib64/squid/cachemgr.cgi
183 Note: File context can be temporarily modified with the chcon command.
186 If you want to permanently change the file context you need to use the
187 semanage fcontext command. This will modify the SELinux labeling data‐
188 base. You will need to use restorecon to apply the labels.
189
192 semanage fcontext can also be used to manipulate default file context
193 mappings.
194 semanage permissive can also be used to manipulate whether or not a
196 process type is permissive.
197 semanage module can also be used to enable/disable/install/remove pol‐
199 icy modules.
200 semanage boolean can also be used to manipulate the booleans
202 system-config-selinux is a GUI tool available to customize SELinux pol‐
205 icy settings.
