6 man2html_script_selinux - Security Enhanced Linux Policy for the
7 man2html_script processes
8
10 Security-Enhanced Linux secures the man2html_script processes via flex‐
11 ible mandatory access control.
12 The man2html_script processes execute with the man2html_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 man2html_script_t
20
24 The man2html_script_t SELinux type can be entered via the
25 man2html_script_exec_t, shell_exec_t, man2html_script_exec_t file
26 types.
27 The default entrypoint paths for the man2html_script_t domain are the
29 following:
30 /usr/lib/man2html/cgi-bin/man/mansec, /usr/lib/man2html/cgi-
32 bin/man/man2html, /usr/lib/man2html/cgi-bin/man/manwhatis, /bin/d?ash,
33 /bin/zsh.*, /bin/ksh.*, /usr/bin/d?ash, /usr/bin/ksh.*, /usr/bin/zsh.*,
34 /bin/esh, /bin/mksh, /bin/sash, /bin/tcsh, /bin/yash, /bin/bash,
35 /bin/fish, /bin/bash2, /usr/bin/esh, /usr/bin/sash, /usr/bin/tcsh,
36 /usr/bin/yash, /usr/bin/mksh, /usr/bin/fish, /usr/bin/bash, /sbin/nolo‐
37 gin, /usr/sbin/sesh, /usr/bin/bash2, /usr/sbin/smrsh, /usr/bin/scponly,
38 /usr/sbin/nologin, /usr/libexec/sesh, /usr/sbin/scponlyc, /usr/bin/git-
39 shell, /usr/libexec/sudo/sesh, /usr/bin/cockpit-bridge,
40 /usr/libexec/cockpit-agent, /usr/libexec/git-core/git-shell,
41 /usr/lib/man2html/cgi-bin/man/mansec, /usr/lib/man2html/cgi-
42 bin/man/man2html, /usr/lib/man2html/cgi-bin/man/manwhatis

45 SELinux defines process types (domains) for each process running on the
46 system
47 You can see the context of a process using the -Z option to ps
49 Policy governs the access confined processes have to files. SELinux
51 man2html_script policy is very flexible allowing users to setup their
52 man2html_script processes in as secure a method as possible.
53 The following process types are defined for man2html_script:
55 man2html_script_t
57 Note: semanage permissive -a man2html_script_t can be used to make the
59 process type man2html_script_t permissive. SELinux does not deny access
60 to permissive process types, but the AVC (SELinux denials) messages are
61 still generated.
62
65 SELinux policy is customizable based on least access required.
66 man2html_script policy is extremely flexible and has several booleans
67 that allow you to manipulate the policy and run man2html_script with
68 the tightest access possible.
69 If you want to deny any process from ptracing or debugging any other
73 processes, you must turn on the deny_ptrace boolean. Enabled by
74 default.
75 setsebool -P deny_ptrace 1
77 If you want to allow any process to mmap any file on system with
81 attribute file_type, you must turn on the domain_can_mmap_files bool‐
82 ean. Enabled by default.
83 setsebool -P domain_can_mmap_files 1
85 If you want to allow all domains write to kmsg_device, while kernel is
89 executed with systemd.log_target=kmsg parameter, you must turn on the
90 domain_can_write_kmsg boolean. Disabled by default.
91 setsebool -P domain_can_write_kmsg 1
93 If you want to allow all domains to use other domains file descriptors,
97 you must turn on the domain_fd_use boolean. Enabled by default.
98 setsebool -P domain_fd_use 1
100 If you want to allow all domains to have the kernel load modules, you
104 must turn on the domain_kernel_load_modules boolean. Disabled by
105 default.
106 setsebool -P domain_kernel_load_modules 1
108 If you want to allow all domains to execute in fips_mode, you must turn
112 on the fips_mode boolean. Enabled by default.
113 setsebool -P fips_mode 1
115 If you want to enable reading of urandom for all domains, you must turn
119 on the global_ssp boolean. Disabled by default.
120 setsebool -P global_ssp 1
122 If you want to allow httpd cgi support, you must turn on the
126 httpd_enable_cgi boolean. Disabled by default.
127 setsebool -P httpd_enable_cgi 1
129 If you want to allow system to run with NIS, you must turn on the
133 nis_enabled boolean. Disabled by default.
134 setsebool -P nis_enabled 1
136
140 The SELinux process type man2html_script_t can manage files labeled
141 with the following file types. The paths listed are the default paths
142 for these file types. Note the processes UID still need to have DAC
143 permissions.
144 man2html_rw_content_t
146 /var/cache/man2html(/.*)?
148
151 SELinux requires files to have an extended attribute to define the file
152 type.
153 You can see the context of a file using the -Z option to ls
155 Policy governs the access confined processes have to these files.
157 SELinux man2html_script policy is very flexible allowing users to setup
158 their man2html_script processes in as secure a method as possible.
159 The following file types are defined for man2html_script:
161 man2html_script_exec_t
165 - Set files with the man2html_script_exec_t type, if you want to tran‐
167 sition an executable to the man2html_script_t domain.
168 Paths:
171 /usr/lib/man2html/cgi-bin/man/mansec, /usr/lib/man2html/cgi-
172 bin/man/man2html, /usr/lib/man2html/cgi-bin/man/manwhatis
173 Note: File context can be temporarily modified with the chcon command.
176 If you want to permanently change the file context you need to use the
177 semanage fcontext command. This will modify the SELinux labeling data‐
178 base. You will need to use restorecon to apply the labels.
179
182 semanage fcontext can also be used to manipulate default file context
183 mappings.
184 semanage permissive can also be used to manipulate whether or not a
186 process type is permissive.
187 semanage module can also be used to enable/disable/install/remove pol‐
189 icy modules.
190 semanage boolean can also be used to manipulate the booleans
192 system-config-selinux is a GUI tool available to customize SELinux pol‐
195 icy settings.
