Why systemd-logind want getattr on /dev/shm/spice.*? Thank you. I'm having the same issue:
type=AVC msg=audit(1417441202.817:39907): avc: denied { getattr } for pid=1249 comm="systemd-logind" path="/dev/shm/spice.8885" dev="tmpfs" ino=221317 scontext=system_u:system_r:systemd_logind_t:s0 tcontext=system_u:object_r:svirt_tmpfs_t:s0 tclass=file permissive=1
Suggested policy fix:
# grep 1417441202.817:39907 /var/log/audit/audit.log | audit2allow
#============= systemd_logind_t ==============
allow systemd_logind_t svirt_tmpfs_t:file getattr;
Relevant package versions:
selinux-policy-3.13.1-92.fc21.noarch

(In reply to Lukas Vrabec from comment #1) > Why systemd-logind want getattr on /dev/shm/spice.*? > Thank you. logind now removes POSIX SHM segments of all users that log out. This is configured via the RemoveIPC= option in logind.conf. Description of problem: I upgraded from F20 to F21 using FedUp. Using Virt-Manager, I then powered on 2 existing VMs that both have "Display Spice", "Channel spice", and "Video XQL".

Description of problem: SELinux is preventing /usr/lib/systemd/systemd-logind from 'getattr' accesses on the file /dev/shm/spice.2372. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that systemd-logind should be allowed getattr access on the spice.2372 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-logind /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:systemd_logind_t:s0 Target Context system_u:object_r:svirt_tmpfs_t:s0 Target Objects /dev/shm/spice.2372 [ file ] Source systemd-logind Source Path /usr/lib/systemd/systemd-logind Port <Unknown> Host (removed) Source RPM Packages systemd-216-5.fc21.x86_64 Target RPM Packages Policy RPM selinux-policy-3.13.1-92.fc21.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.17.2-300.fc21.x86_64 #1 SMP Thu Oct 30 19:23:48 UTC 2014 x86_64 x86_64 Alert Count 2 First Seen 2014-11-02 20:04:31 EST Last Seen 2014-11-02 20:04:48 EST Local ID 3626ac9d-7bbc-47c0-9d22-7effa29424a0 Raw Audit Messages type=AVC msg=audit(1414976688.625:425): avc: denied { getattr } for pid=1295 comm="systemd-logind" path="/dev/shm/spice.2372" dev="tmpfs" ino=27522 scontext=system_u:system_r:systemd_logind_t:s0 tcontext=system_u:object_r:svirt_tmpfs_t:s0 tclass=file permissive=0 type=SYSCALL msg=audit(1414976688.625:425): arch=x86_64 syscall=newfstatat success=no exit=EACCES a0=16 a1=7fdb3e36c02b a2=7fff03ba8570 a3=100 items=0 ppid=1 pid=1295 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=systemd-logind exe=/usr/lib/systemd/systemd-logind subj=system_u:system_r:systemd_logind_t:s0 key=(null) Hash: systemd-logind,systemd_logind_t,svirt_tmpfs_t,file,getattr Version-Release number of selected component: selinux-policy-3.13.1-92.fc21.noarch Additional info: reporter: libreport-2.3.0 hashmarkername: setroubleshoot kernel: 3.17.2-300.fc21.x86_64 type: libreport
