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.
72 Enabled 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 passenger_log_t
84 /var/log/passenger.*
86 passenger_var_lib_t
88 /var/lib/passenger(/.*)?
90 passenger_var_run_t
92 /var/run/passenger(/.*)?
94 puppet_var_lib_t
96 /var/lib/puppet(/.*)?
98
101 SELinux requires files to have an extended attribute to define the file
102 type.
103 You can see the context of a file using the -Z option to ls
105 Policy governs the access confined processes have to these files.
107 SELinux passenger policy is very flexible allowing users to setup their
108 passenger processes in as secure a method as possible.
109 STANDARD FILE CONTEXT
111 SELinux defines the file context types for the passenger, if you wanted
113 to store files with these types in a diffent paths, you need to execute
114 the semanage command to sepecify alternate labeling and then use
115 restorecon to put the labels on disk.
116 semanage fcontext -a -t passenger_var_run_t '/srv/mypassenger_con‐
118 tent(/.*)?'
119 restorecon -R -v /srv/mypassenger_content
120 Note: SELinux often uses regular expressions to specify labels that
122 match multiple files.
123 The following file types are defined for passenger:
125 passenger_exec_t
129 - Set files with the passenger_exec_t type, if you want to transition
131 an executable to the passenger_t domain.
132 Paths:
135 /usr/share/.*/gems/.*/helper-scripts/prespawn,
136 /usr/lib/gems/.*/Passenger.*, /usr/lib/gems/.*/Application‐
137 PoolServerExecutable, /usr/share/gems/.*/Passenger.*,
138 /usr/share/gems/.*/ApplicationPoolServerExecutable
139 passenger_log_t
142 - Set files with the passenger_log_t type, if you want to treat the
144 data as passenger log data, usually stored under the /var/log direc‐
145 tory.
146 passenger_tmp_t
150 - Set files with the passenger_tmp_t type, if you want to store passen‐
152 ger temporary files in the /tmp directories.
153 passenger_var_lib_t
157 - Set files with the passenger_var_lib_t type, if you want to store the
159 passenger files under the /var/lib directory.
160 passenger_var_run_t
164 - Set files with the passenger_var_run_t type, if you want to store the
166 passenger files under the /run or /var/run directory.
167 Note: File context can be temporarily modified with the chcon command.
171 If you want to permanently change the file context you need to use the
172 semanage fcontext command. This will modify the SELinux labeling data‐
173 base. You will need to use restorecon to apply the labels.
174
177 semanage fcontext can also be used to manipulate default file context
178 mappings.
179 semanage permissive can also be used to manipulate whether or not a
181 process type is permissive.
182 semanage module can also be used to enable/disable/install/remove pol‐
184 icy modules.
185 semanage boolean can also be used to manipulate the booleans
187 system-config-selinux is a GUI tool available to customize SELinux pol‐
190 icy settings.
