Description of problem: This is a fresh rawhide installation upgraded by dnf plugin from a fresh f25 installation. I was told in IRC the events are due to a kernel change where the order of dac_read_search and dac_override changed to fix check dac_read_search SELinux is preventing login from using the 'dac_read_search' capabilities. ***** Plugin dac_override (91.4 confidence) suggests ********************** If you want to help identify if domain needs this access or you have a file with the wrong permissions on your system Then turn on full auditing to get path information about the offending file and generate the error again. Do Turn on full auditing # auditctl -w /etc/shadow -p w Try to recreate AVC. Then execute # ausearch -m avc -ts recent If you see PATH record check ownership/permissions on file, and fix it, otherwise report as a bugzilla. ***** Plugin catchall (9.59 confidence) suggests ************************** If you believe that login should have the dac_read_search capability 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 'login' --raw | audit2allow -M my-login # semodule -X 300 -i my-login.pp Additional Information: Source Context system_u:system_r:local_login_t:s0-s0:c0.c1023 Target Context system_u:system_r:local_login_t:s0-s0:c0.c1023 Target Objects Unknown [ capability ] Source login Source Path login Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-255.fc27.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.12.0-0.rc3.git0.2.fc27.x86_64 #1 SMP Tue May 30 19:36:51 UTC 2017 x86_64 x86_64 Alert Count 1 First Seen 2017-06-05 21:40:47 CEST Last Seen 2017-06-05 21:40:47 CEST Local ID 955c23f4-1986-4c56-9856-ecccd299043b Raw Audit Messages type=AVC msg=audit(1496691647.830:1515): avc: denied { dac_read_search } for pid=11580 comm="login" capability=2 scontext=system_u:system_r:local_login_t:s0-s0:c0.c1023 tcontext=system_u:system_r:local_login_t:s0-s0:c0.c1023 tclass=capability permissive=0 Hash: login,local_login_t,local_login_t,capability,dac_read_search Version-Release number of selected component: selinux-policy-3.13.1-255.fc27.noarch Additional info: component: selinux-policy reporter: libreport-2.9.1 hashmarkername: setroubleshoot kernel: 4.12.0-0.rc3.git0.2.fc27.x86_64 type: libreport
