NAME

6       rpm_selinux - Security Enhanced Linux Policy for the rpm processes
7

DESCRIPTION

9       Security-Enhanced  Linux  secures the rpm processes via flexible manda‐
10       tory access control.
11
12       The rpm processes execute with the rpm_t SELinux type. You can check if
13       you  have  these processes running by executing the ps command with the
14       -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep rpm_t
19

21

ENTRYPOINTS

23       The  rpm_t  SELinux  type  can   be   entered   via   the   rpm_exec_t,
24       rpm_script_exec_t, debuginfo_exec_t file types.
25
26       The default entrypoint paths for the rpm_t domain are the following:
27
28       /usr/bin/dnf-[0-9]+,                 /usr/sbin/rhn_check-[0-9]+.[0-9]+,

PROCESS TYPES

45       SELinux defines process types (domains) for each process running on the
46       system
47
48       You can see the context of a process using the -Z option to ps
49
50       Policy governs the access confined processes have  to  files.   SELinux
51       rpm policy is very flexible allowing users to setup their rpm processes
52       in as secure a method as possible.
53
54       The following process types are defined for rpm:
55
56       rpm_t, rpmdb_t, rpm_script_t
57
58       Note: semanage permissive -a rpm_t can be used to make the process type
59       rpm_t  permissive.  SELinux  does not deny access to permissive process
60       types, but the AVC (SELinux denials) messages are still generated.
61
62

BOOLEANS

64       SELinux policy is customizable based on  least  access  required.   rpm
65       policy is extremely flexible and has several booleans that allow you to
66       manipulate the policy and run rpm with the tightest access possible.
67
68
69
70       If you want to control the ability to mmap a low area  of  the  address
71       space,  as  configured  by /proc/sys/vm/mmap_min_addr, you must turn on
72       the mmap_low_allowed boolean. Disabled by default.
73
74       setsebool -P mmap_low_allowed 1
75
76
77
78       If you want to disable kernel module loading, you must turn on the  se‐
79       cure_mode_insmod boolean. Enabled by default.
80
81       setsebool -P secure_mode_insmod 1
82
83
84
85       If  you  want to allow unconfined executables to make their heap memory
86       executable.  Doing this is a really  bad  idea.  Probably  indicates  a
87       badly  coded  executable, but could indicate an attack. This executable
88       should be reported in bugzilla, you must turn  on  the  selinuxuser_ex‐
89       echeap boolean. Disabled by default.
90
91       setsebool -P selinuxuser_execheap 1
92
93
94
95       If  you  want  to allow unconfined executables to make their stack exe‐
96       cutable.  This should never, ever be necessary.  Probably  indicates  a
97       badly  coded  executable, but could indicate an attack. This executable
98       should be reported in bugzilla, you must turn on the  selinuxuser_exec‐
99       stack boolean. Enabled by default.
100
101       setsebool -P selinuxuser_execstack 1
102
103
104

MANAGED FILES

106       The  SELinux  process type rpm_t can manage files labeled with the fol‐
107       lowing file types.  The paths listed are the default  paths  for  these
108       file types.  Note the processes UID still need to have DAC permissions.
109
110       file_type
111
112            all files on the system
113
114

FILE CONTEXTS

116       SELinux requires files to have an extended attribute to define the file
117       type.
118
119       You can see the context of a file using the -Z option to ls
120
121       Policy governs the access  confined  processes  have  to  these  files.
122       SELinux  rpm  policy is very flexible allowing users to setup their rpm
123       processes in as secure a method as possible.
124
125       EQUIVALENCE DIRECTORIES
126
127
128       rpm policy stores data with multiple different file context types under
129       the  /var/lib/rpm  directory.  If you would like to store the data in a
130       different directory you can use  the  semanage  command  to  create  an
131       equivalence  mapping.   If you wanted to store this data under the /srv
132       directory you would execute the following command:
133
134       semanage fcontext -a -e /var/lib/rpm /srv/rpm
135       restorecon -R -v /srv/rpm
136
137       STANDARD FILE CONTEXT
138
139       SELinux defines the file context types for the rpm, if  you  wanted  to
140       store  files  with  these types in a diffent paths, you need to execute
141       the semanage command to specify alternate labeling  and  then  use  re‐
142       storecon to put the labels on disk.
143
144       semanage fcontext -a -t rpm_script_tmpfs_t '/srv/myrpm_content(/.*)?'
145       restorecon -R -v /srv/myrpm_content
146
147       Note:  SELinux  often  uses  regular expressions to specify labels that
148       match multiple files.
149
150       The following file types are defined for rpm:
151
152
153
154       rpm_exec_t
155
156       - Set files with the rpm_exec_t type, if you want to transition an exe‐
157       cutable to the rpm_t domain.

287

COMMANDS

289       semanage  fcontext  can also be used to manipulate default file context
290       mappings.
291
292       semanage permissive can also be used to manipulate  whether  or  not  a
293       process type is permissive.
294
295       semanage  module can also be used to enable/disable/install/remove pol‐
296       icy modules.
297
298       semanage boolean can also be used to manipulate the booleans
299
300
301       system-config-selinux is a GUI tool available to customize SELinux pol‐
302       icy settings.
