Description of problem: SELinux is preventing dhclient from 'getattr' accesses on the chr_file /dev/random. ***** Plugin catchall_boolean (89.3 confidence) suggests ****************** If you want to allow authlogin to nsswitch use ldap Then you must tell SELinux about this by enabling the 'authlogin_nsswitch_use_ldap' boolean. Do setsebool -P authlogin_nsswitch_use_ldap 1 ***** Plugin catchall (11.6 confidence) suggests ************************** If you believe that dhclient should be allowed getattr access on the random chr_file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'dhclient' --raw | audit2allow -M my-dhclient # semodule -X 300 -i my-dhclient.pp Additional Information: Source Context system_u:system_r:dhcpc_t:s0 Target Context system_u:object_r:random_device_t:s0 Target Objects /dev/random [ chr_file ] Source dhclient Source Path dhclient Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.14.2-32.fc29.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 4.19.0-0.rc1.git0.1.fc30.x86_64 #1 SMP Mon Aug 27 13:01:19 UTC 2018 x86_64 x86_64 Alert Count 3 First Seen 2018-08-29 00:29:50 +05 Last Seen 2018-09-01 13:03:05 +05 Local ID 65ae0094-de4c-40ad-af57-c24f00b3f1e2 Raw Audit Messages type=AVC msg=audit(1535788985.624:648): avc: denied { getattr } for pid=2233 comm="dhclient" path="/dev/random" dev="devtmpfs" ino=1032 scontext=system_u:system_r:dhcpc_t:s0 tcontext=system_u:object_r:random_device_t:s0 tclass=chr_file permissive=1 Hash: dhclient,dhcpc_t,random_device_t,chr_file,getattr Version-Release number of selected component: selinux-policy-3.14.2-32.fc29.noarch Additional info: component: selinux-policy reporter: libreport-2.9.5 hashmarkername: setroubleshoot kernel: 4.19.0-0.rc1.git4.1.fc30.x86_64 type: libreport
