Perhaps that explains why the recent refpolicy is not starting OpenSuse processes in the right context. Is the current refpolicy known to work in System V init -based systems? Oh right sorry, now i see it is system_r not sysadm_r. Looks like init is not in the right domain i guess. I am not sure what the reason for this is but my guess is that its (or some of its) executable(s) is mislabelled, although that still does not explain how it got to sysadm_t. I am interested to hear what others say about this issue. > > -----Original Message----- > From: Dominick Grift [mailto:domg472@xxxxxxxxx] > Sent: Tuesday, February 16, 2010 10:22 AM > To: Alan Rouse > Cc: 'selinux@xxxxxxxxxxxxx' > Subject: Re: SELinux Policy in OpenSUSE 11.2 > > On 02/16/2010 03:55 PM, Alan Rouse wrote: > le >> type=AVC msg=audit(1265904613.689:203): avc: denied { execstack } >> for pid=2382 comm="cupsd" scontext=system_u:system_r:sysadm_t >> tcontext=system_u:system_r:sysadm_t tclass=process type=AVC >> msg=audit(1265904613.690:204): avc: denied { execmem } for pid=2382 >> comm="cupsd" scontext=system_u:system_r:sysadm_t >> tcontext=system_u:system_r:sysadm_t tclass=process type=AVC >> msg=audit(1265904614.260:205): avc: denied { read write } for >> pid=2448 comm="smartd" name="sda" dev=tmpfs ino=1749 >> scontext=system_u:system_r:sysadm_t >> tcontext=system_u:object_r:fixed_disk_device_t tclass=blk_file >> type=AVC msg=audit(1265904614.260:206): avc: denied { open } for >> pid=2448 comm="smartd" name="sda" dev=tmpfs ino=1749 >> scontext=system_u:system_r:sysadm_t >> tcontext=system_u:object_r:fixed_disk_device_t tclass=blk_file >> type=AVC msg=audit(1265904614.261:207): avc: denied { ioctl } for >> pid=2448 comm="smartd" path="/dev/sda" dev=tmpfs ino=1749 >> scontext=system_u:system_r:sysadm_t >> tcontext=system_u:object_r:fixed_disk_device_t tclass=blk_file >> type=AVC msg=audit(1265904615.964:209): avc: denied { read } for >> pid=2337 comm="auditd" scontext=system_u:system_r:sysadm_t >> tcontext=system_u:system_r:sysadm_t tclass=netlink_audit_socket >> type=AVC msg=audit(1265904616.063:212): avc: denied { read } for >> pid=308 comm="udevd" scontext=system_u:system_r:sysadm_t >> tcontext=system_u:system_r:sysadm_t >> tclass=netlink_kobject_uevent_socket >> type=AVC msg=audit(1265904616.063:213): avc: denied { write } for >> pid=308 comm="udevd" scontext=system_u:system_r:sysadm_t >> tcontext=system_u:system_r:sysadm_t >> tclass=netlink_kobject_uevent_socket > > With regard to the AVC denials above it seems that these services (cupsd, smartd, auditd and udevd) run in the wrong domain.
