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 bin_t,
25 shell_exec_t, usr_t, ldconfig_exec_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. /bin/d?ash, /bin/ksh.*, /bin/zsh.*,
32 /usr/bin/d?ash, /usr/bin/ksh.*, /usr/bin/zsh.*, /bin/esh, /bin/bash,
33 /bin/fish, /bin/mksh, /bin/sash, /bin/tcsh, /bin/yash, /bin/bash2,
34 /usr/bin/esh, /sbin/nologin, /usr/bin/bash, /usr/bin/fish,
35 /usr/bin/mksh, /usr/bin/sash, /usr/bin/tcsh, /usr/bin/yash,
36 /usr/bin/bash2, /usr/sbin/sesh, /usr/sbin/smrsh, /usr/bin/scponly,
37 /usr/libexec/sesh, /usr/sbin/nologin, /usr/bin/git-shell,
38 /usr/sbin/scponlyc, /usr/libexec/sudo/sesh, /usr/bin/cockpit-bridge,
39 /usr/libexec/cockpit-agent, /usr/libexec/git-core/git-shell, /opt/.*,
40 /usr/.*, /emul/.*, /export(/.*)?, /ostree(/.*)?,
41 /usr/doc(/.*)?/lib(/.*)?, /usr/inclu.e(/.*)?, /usr/share/rpm(/.*)?,
42 /usr/share/doc(/.*)?/README.*, /usr/lib/modules(/.*)/vmlinuz,
43 /usr/lib/modules(/.*)/initramfs.img, /usr/lib/sysimage(/.*)?,
44 /usr/lib/ostree-boot(/.*)?, /opt, /usr, /emul, /sbin/sln,
45 /usr/sbin/sln, /sbin/ldconfig, /usr/sbin/ldconfig

48 SELinux defines process types (domains) for each process running on the
49 system
50
51 You can see the context of a process using the -Z option to ps
52
53 Policy governs the access confined processes have to files. SELinux
54 rpm_script policy is very flexible allowing users to setup their
55 rpm_script processes in as secure a method as possible.
56
57 The following process types are defined for rpm_script:
58
59 rpm_script_t
60
61 Note: semanage permissive -a rpm_script_t can be used to make the
62 process type rpm_script_t permissive. SELinux does not deny access to
63 permissive process types, but the AVC (SELinux denials) messages are
64 still generated.
65
66
68 SELinux policy is customizable based on least access required.
69 rpm_script policy is extremely flexible and has several booleans that
70 allow you to manipulate the policy and run rpm_script with the tightest
71 access possible.
72
73
74
75 If you want to control the ability to mmap a low area of the address
76 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
77 the mmap_low_allowed boolean. Disabled by default.
78
79 setsebool -P mmap_low_allowed 1
80
81
82
83 If you want to disable kernel module loading, you must turn on the se‐
84 cure_mode_insmod boolean. Enabled by default.
85
86 setsebool -P secure_mode_insmod 1
87
88
89
90 If you want to allow unconfined executables to make their heap memory
91 executable. Doing this is a really bad idea. Probably indicates a
92 badly coded executable, but could indicate an attack. This executable
93 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
94 echeap boolean. Disabled by default.
95
96 setsebool -P selinuxuser_execheap 1

101 The SELinux process type rpm_script_t can manage files labeled with the
102 following file types. The paths listed are the default paths for these
103 file types. Note the processes UID still need to have DAC permissions.
104
105 file_type
106
107 all files on the system
108
109
111 semanage fcontext can also be used to manipulate default file context
112 mappings.
113
114 semanage permissive can also be used to manipulate whether or not a
115 process type is permissive.
116
117 semanage module can also be used to enable/disable/install/remove pol‐
118 icy modules.
119
120 semanage boolean can also be used to manipulate the booleans
121
122
123 system-config-selinux is a GUI tool available to customize SELinux pol‐
124 icy settings.
