6 passenger_selinux - Security Enhanced Linux Policy for the passenger
7 processes
8
10 Security-Enhanced Linux secures the passenger processes via flexible
11 mandatory access control.
12 The passenger processes execute with the passenger_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16 For example:
18 ps -eZ | grep passenger_t
20
24 The passenger_t SELinux type can be entered via the passenger_exec_t
25 file type.
26 The default entrypoint paths for the passenger_t domain are the follow‐
28 ing:
29 /usr/share/.*/gems/.*/helper-scripts/prespawn, /usr/lib/gems/.*/Passen‐
31 ger.*, /usr/lib/gems/.*/ApplicationPoolServerExecutable,
32 /usr/share/gems/.*/Passenger.*, /usr/share/gems/.*/Application‐
33 PoolServerExecutable
34
36 SELinux defines process types (domains) for each process running on the
37 system
38 You can see the context of a process using the -Z option to ps
40 Policy governs the access confined processes have to files. SELinux
42 passenger policy is very flexible allowing users to setup their passen‐
43 ger processes in as secure a method as possible.
44 The following process types are defined for passenger:
46 passenger_t
48 Note: semanage permissive -a passenger_t can be used to make the
50 process type passenger_t permissive. SELinux does not deny access to
51 permissive process types, but the AVC (SELinux denials) messages are
52 still generated.
53
56 SELinux policy is customizable based on least access required. passen‐
57 ger policy is extremely flexible and has several booleans that allow
58 you to manipulate the policy and run passenger with the tightest access
59 possible.
60 If you want to allow all domains to execute in fips_mode, you must turn
64 on the fips_mode boolean. Enabled by default.
65 setsebool -P fips_mode 1
67 If you want to allow Apache to run in stickshift mode, not transition
71 to passenger, you must turn on the httpd_run_stickshift boolean. En‐
72 abled by default.
73 setsebool -P httpd_run_stickshift 1
75
79 The SELinux process type passenger_t can manage files labeled with the
80 following file types. The paths listed are the default paths for these
81 file types. Note the processes UID still need to have DAC permissions.
82 krb5_host_rcache_t
84 /var/tmp/krb5_0.rcache2
86 /var/cache/krb5rcache(/.*)?
87 /var/tmp/nfs_0
88 /var/tmp/DNS_25
89 /var/tmp/host_0
90 /var/tmp/imap_0
91 /var/tmp/HTTP_23
92 /var/tmp/HTTP_48
93 /var/tmp/ldap_55
94 /var/tmp/ldap_487
95 /var/tmp/ldapmap1_0
96 passenger_log_t
98 /var/log/passenger.*
100 passenger_tmp_t
102 passenger_var_lib_t
105 /var/lib/passenger(/.*)?
107 passenger_var_run_t
109 /var/run/passenger(/.*)?
111 puppet_var_lib_t
113 /var/lib/puppet(/.*)?
115
118 SELinux requires files to have an extended attribute to define the file
119 type.
120 You can see the context of a file using the -Z option to ls
122 Policy governs the access confined processes have to these files.
124 SELinux passenger policy is very flexible allowing users to setup their
125 passenger processes in as secure a method as possible.
126 STANDARD FILE CONTEXT
128 SELinux defines the file context types for the passenger, if you wanted
130 to store files with these types in a diffent paths, you need to execute
131 the semanage command to specify alternate labeling and then use re‐
132 storecon to put the labels on disk.
133 semanage fcontext -a -t passenger_var_run_t '/srv/mypassenger_con‐
135 tent(/.*)?'
136 restorecon -R -v /srv/mypassenger_content
137 Note: SELinux often uses regular expressions to specify labels that
139 match multiple files.
140 The following file types are defined for passenger:
142 passenger_exec_t
146 - Set files with the passenger_exec_t type, if you want to transition
148 an executable to the passenger_t domain.
149 Paths:
152 /usr/share/.*/gems/.*/helper-scripts/prespawn,
153 /usr/lib/gems/.*/Passenger.*, /usr/lib/gems/.*/Application‐
154 PoolServerExecutable, /usr/share/gems/.*/Passenger.*,
155 /usr/share/gems/.*/ApplicationPoolServerExecutable
156 passenger_log_t
159 - Set files with the passenger_log_t type, if you want to treat the
161 data as passenger log data, usually stored under the /var/log direc‐
162 tory.
163 passenger_tmp_t
167 - Set files with the passenger_tmp_t type, if you want to store passen‐
169 ger temporary files in the /tmp directories.
170 passenger_var_lib_t
174 - Set files with the passenger_var_lib_t type, if you want to store the
176 passenger files under the /var/lib directory.
177 passenger_var_run_t
181 - Set files with the passenger_var_run_t type, if you want to store the
183 passenger files under the /run or /var/run directory.
184 Note: File context can be temporarily modified with the chcon command.
188 If you want to permanently change the file context you need to use the
189 semanage fcontext command. This will modify the SELinux labeling data‐
190 base. You will need to use restorecon to apply the labels.
191
194 semanage fcontext can also be used to manipulate default file context
195 mappings.
196 semanage permissive can also be used to manipulate whether or not a
198 process type is permissive.
199 semanage module can also be used to enable/disable/install/remove pol‐
201 icy modules.
202 semanage boolean can also be used to manipulate the booleans
204 system-config-selinux is a GUI tool available to customize SELinux pol‐
207 icy settings.
