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 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 For example:
18 ps -eZ | grep rpm_script_t
20
24 The rpm_script_t SELinux type can be entered via the ldconfig_exec_t,
25 bin_t, shell_exec_t, usr_t file types.
26 The default entrypoint paths for the rpm_script_t domain are the fol‐
28 lowing:
29 All executeables 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,

40 agent, /usr/libexec/git-core/git-shell, /opt/.*, /usr/.*, /emul/.*,

48 SELinux defines process types (domains) for each process running on the
49 system
50 You can see the context of a process using the -Z option to ps
52 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 The following process types are defined for rpm_script:
58 rpm_script_t
60 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
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 If you want to allow users to resolve user passwd entries directly from
76 ldap rather then using a sssd server, you must turn on the authlo‐
77 gin_nsswitch_use_ldap boolean. Disabled by default.
78 setsebool -P authlogin_nsswitch_use_ldap 1
80 If you want to deny user domains applications to map a memory region as
84 both executable and writable, this is dangerous and the executable
85 should be reported in bugzilla, you must turn on the deny_execmem bool‐
86 ean. Enabled by default.
87 setsebool -P deny_execmem 1
89 If you want to allow all domains to execute in fips_mode, you must turn
93 on the fips_mode boolean. Enabled by default.
94 setsebool -P fips_mode 1
96 If you want to allow confined applications to run with kerberos, you
100 must turn on the kerberos_enabled boolean. Enabled by default.
101 setsebool -P kerberos_enabled 1
103 If you want to control the ability to mmap a low area of the address
107 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
108 the mmap_low_allowed boolean. Disabled by default.
109 setsebool -P mmap_low_allowed 1
111 If you want to allow system to run with NIS, you must turn on the
115 nis_enabled boolean. Disabled by default.
116 setsebool -P nis_enabled 1
118 If you want to allow confined applications to use nscd shared memory,
122 you must turn on the nscd_use_shm boolean. Disabled by default.
123 setsebool -P nscd_use_shm 1
125 If you want to disable kernel module loading, you must turn on the
129 secure_mode_insmod boolean. Enabled by default.
130 setsebool -P secure_mode_insmod 1
132 If you want to allow unconfined executables to make their heap memory
136 executable. Doing this is a really bad idea. Probably indicates a
137 badly coded executable, but could indicate an attack. This executable
138 should be reported in bugzilla, you must turn on the selin‐
139 uxuser_execheap boolean. Disabled by default.
140 setsebool -P selinuxuser_execheap 1
142 If you want to allow unconfined executables to make their stack exe‐
146 cutable. This should never, ever be necessary. Probably indicates a
147 badly coded executable, but could indicate an attack. This executable
148 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
149 stack boolean. Enabled by default.
150 setsebool -P selinuxuser_execstack 1

156 The SELinux process type rpm_script_t can manage files labeled with the
157 following file types. The paths listed are the default paths for these
158 file types. Note the processes UID still need to have DAC permissions.
159 file_type
161 all files on the system
163
166 semanage fcontext can also be used to manipulate default file context
167 mappings.
168 semanage permissive can also be used to manipulate whether or not a
170 process type is permissive.
171 semanage module can also be used to enable/disable/install/remove pol‐
173 icy modules.
174 semanage boolean can also be used to manipulate the booleans
176 system-config-selinux is a GUI tool available to customize SELinux pol‐
179 icy settings.
