Fixed in selinux-policy-3.6.1-9.fc11 |
Description of problem: selinux-policy-targeted-3.6.1-6.fc11 causes avc denied messages in /var/log/audit/audit.log, and blocks sshd's access to /root/.ssh/authorized_hosts. The default file context for these files is system_u:object_r:admin_home_t:s0, to which sshd is not allowed access. Turning off enforcing or changing file context to system_u:object_r:home_ssh_t:s0 clears up the problem. Version-Release number of selected component (if applicable): 3.6.1-6.fc11 How reproducible: Always Steps to Reproduce: 1. Set up a public key and add it to rawhide system's /root/.ssh/authorized_hosts 2. Use ssh from another system to login as root on rawhide system. 3. Login by providing password. 4. Look at /var/log/audit/audit.log 5. setenforce 0 6. Repeat steps 2-4, step 3 will allow passwordless login. 7. setenforce 1 8. chcon -R system_u:object_r:home_ssh_t:s0 /root/.ssh 9. Repeat step 6. Actual results: Passwordless access denied because sshd denied access to /root/.ssh by default. audit.log entry example: type=AVC msg=audit(1228775617.887:106): avc: denied { read } for pid=3338 comm="sshd" name="authorized_keys" dev=sda8 ino=343691 scontext=system_u:system_r:sshd_t:s0-s0:c0.c1023 tcontext=unconfined_u:object_r:admin_home_t:s0 tclass=file Expected results: sshd should be allowed access to /root/.ssh files regardless of whether enforcing is enabled or not. Additional info: Please either fix the default context for /root/.ssh, or change sshd's policy to allow access to admin_home_t files. Probably the first fix is preferable.
