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

21

ENTRYPOINTS

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

PROCESS TYPES

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

BOOLEANS

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

103

MANAGED FILES

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

FILE CONTEXTS

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

COMMANDS

283       semanage fcontext can also be used to manipulate default  file  context
284       mappings.
285
286       semanage  permissive  can  also  be used to manipulate whether or not a
287       process type is permissive.
288
289       semanage module can also be used to enable/disable/install/remove  pol‐
290       icy modules.
291
292       semanage boolean can also be used to manipulate the booleans
293
