6 rpm_script_selinux - Security Enhanced Linux Policy for the rpm_script
7 processes
8
10 Security-Enhanced Linux secures the rpm_script processes via flexible
11 mandatory access control.
12
13 The rpm_script processes execute with the rpm_script_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep rpm_script_t
20
21
22
24 The rpm_script_t SELinux type can be entered via the ldconfig_exec_t,
25 shell_exec_t, bin_t, usr_t file types.
26
27 The default entrypoint paths for the rpm_script_t domain are the fol‐
28 lowing:
29
30 All executables with the default executable label, usually stored in
31 /usr/bin and /usr/sbin. /sbin/sln, /usr/sbin/sln, /sbin/ldconfig,
32 /usr/sbin/ldconfig, /bin/d?ash, /bin/ksh.*, /bin/zsh.*, /usr/bin/d?ash,
33 /usr/bin/ksh.*, /usr/bin/zsh.*, /bin/esh, /bin/bash, /bin/fish,
34 /bin/mksh, /bin/sash, /bin/tcsh, /bin/yash, /bin/bash2, /usr/bin/esh,
35 /sbin/nologin, /usr/bin/bash, /usr/bin/fish, /usr/bin/mksh,
36 /usr/bin/sash, /usr/bin/tcsh, /usr/bin/yash, /usr/bin/bash2,
37 /usr/sbin/sesh, /usr/sbin/smrsh, /usr/bin/scponly, /usr/libexec/sesh,
38 /usr/sbin/nologin, /usr/bin/git-shell, /usr/sbin/scponlyc,
39 /usr/libexec/sudo/sesh, /usr/bin/cockpit-bridge, /usr/libexec/cockpit-
40 agent, /usr/libexec/git-core/git-shell, /opt/.*, /usr/.*, /emul/.*,
41 /export(/.*)?, /ostree(/.*)?, /usr/doc(/.*)?/lib(/.*)?, /usr/in‐
42 clu.e(/.*)?, /usr/share/rpm(/.*)?, /usr/share/doc(/.*)?/README.*,
43 /usr/lib/modules(/.*)/vmlinuz, /usr/lib/modules(/.*)/initramfs.img,
44 /usr/lib/sysimage(/.*)?, /usr/lib/ostree-boot(/.*)?, /opt, /usr, /emul

47 SELinux defines process types (domains) for each process running on the
48 system
49
50 You can see the context of a process using the -Z option to ps
51
52 Policy governs the access confined processes have to files. SELinux
53 rpm_script policy is very flexible allowing users to setup their
54 rpm_script processes in as secure a method as possible.
55
56 The following process types are defined for rpm_script:
57
58 rpm_script_t
59
60 Note: semanage permissive -a rpm_script_t can be used to make the
61 process type rpm_script_t permissive. SELinux does not deny access to
62 permissive process types, but the AVC (SELinux denials) messages are
63 still generated.
64
65
67 SELinux policy is customizable based on least access required.
68 rpm_script policy is extremely flexible and has several booleans that
69 allow you to manipulate the policy and run rpm_script with the tightest
70 access possible.
71
72
73
74 If you want to control the ability to mmap a low area of the address
75 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
76 the mmap_low_allowed boolean. Disabled by default.
77
78 setsebool -P mmap_low_allowed 1
79
80
81
82 If you want to disable kernel module loading, you must turn on the se‐
83 cure_mode_insmod boolean. Enabled by default.
84
85 setsebool -P secure_mode_insmod 1
86
87
88
89 If you want to allow unconfined executables to make their heap memory
90 executable. Doing this is a really bad idea. Probably indicates a
91 badly coded executable, but could indicate an attack. This executable
92 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
93 echeap boolean. Disabled by default.
94
95 setsebool -P selinuxuser_execheap 1
96
97

100 The SELinux process type rpm_script_t can manage files labeled with the
101 following file types. The paths listed are the default paths for these
102 file types. Note the processes UID still need to have DAC permissions.
103
104 file_type
105
106 all files on the system
107
108
110 semanage fcontext can also be used to manipulate default file context
111 mappings.
112
113 semanage permissive can also be used to manipulate whether or not a
114 process type is permissive.
115
116 semanage module can also be used to enable/disable/install/remove pol‐
117 icy modules.
118
119 semanage boolean can also be used to manipulate the booleans
120
121
122 system-config-selinux is a GUI tool available to customize SELinux pol‐
123 icy settings.
