I think we should just label this directory as /var/run/systemd/ask-password-block(/.*)? gen_context(system_u:object_r:systemd_device_t,s0) Lennart is this directory in F16 going to be /var/run/systemd/ask-password(/.*)? gen_context(system_u:object_r:systemd_device_t,s0) I got AVCs with selinux-policy-targeted-3.10.0-43.fc16 which went away when I downgraded to 3.10.0-40.fc16:

Description of problem: ***** Plugin catchall (100. confidence) suggests *************************** If you believe that systemd-tty-ask-password-agent should be allowed read access on the 136:2 fifo_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: # grep systemd-tty-ask /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context unconfined_u:system_r:systemd_passwd_agent_t:s0 Target Context unconfined_u:object_r:init_var_run_t:s0 Target Objects 136:2 [ fifo_file ] Source systemd-tty-ask Source Path /bin/systemd-tty-ask-password-agent Port <Unknown> Host larch.ezono.net Source RPM Packages systemd-26-10.fc15 Target RPM Packages Policy RPM selinux-policy-3.9.16-39.fc15 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name larch.ezono.net Platform Linux larch.ezono.net 2.6.40.6-0.fc15.i686.PAE #1 SMP Tue Oct 4 00:44:38 UTC 2011 i686 i686 Alert Count 5 First Seen Mon Oct 17 14:07:13 2011 Last Seen Mon Oct 17 14:33:15 2011 Local ID c8f9f375-24b1-48fb-b59f-5fcc7f301016 Raw Audit Messages type=AVC msg=audit(1318854795.241:4485): avc: denied { read } for pid=26046 comm="systemd-tty-ask" name="136:2" dev=tmpfs ino=2725891 scontext=unconfined_u:system_r:systemd_passwd_agent_t:s0 tcontext=unconfined_u:object_r:init_var_run_t:s0 tclass=fifo_file type=AVC msg=audit(1318854795.241:4485): avc: denied { open } for pid=26046 comm="systemd-tty-ask" name="136:2" dev=tmpfs ino=2725891 scontext=unconfined_u:system_r:systemd_passwd_agent_t:s0 tcontext=unconfined_u:object_r:init_var_run_t:s0 tclass=fifo_file type=SYSCALL msg=audit(1318854795.241:4485): arch=i386 syscall=open success=yes exit=ESRCH a0=8f44080 a1=88900 a2=0 a3=bfc5c3a4 items=0 ppid=26045 pid=26046 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=pts2 ses=362 comm=systemd-tty-ask exe=/bin/systemd-tty-ask-password-agent subj=unconfined_u:system_r:systemd_passwd_agent_t:s0 key=(null) Hash: systemd-tty-ask,systemd_passwd_agent_t,init_var_run_t,fifo_file,read audit2allow #============= systemd_passwd_agent_t ============== allow systemd_passwd_agent_t init_var_run_t:fifo_file { read open }; audit2allow -R #============= systemd_passwd_agent_t ============== allow systemd_passwd_agent_t init_var_run_t:fifo_file { read open }; Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3.
