I think libvirt would need to relabel the tun_socket to match the svirt_t label to make this secure. *** This bug has been marked as a duplicate of bug 1147057 *** |
Description of problem: Configured multiqueue virtio-net with libvirt, then ran this inside the guest: ethtool -L eth0 combined 4 Where there should be 4 tap FDs allocated to the guest for each queue. FWIW I think this is supposed to work SELinux is preventing /usr/bin/qemu-system-x86_64 from 'attach_queue' accesses on the tun_socket . ***** Plugin catchall (100. confidence) suggests ************************** If you believe that qemu-system-x86_64 should be allowed attach_queue access on the tun_socket 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 qemu-system-x86 /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:svirt_t:s0:c194,c501 Target Context system_u:system_r:virtd_t:s0-s0:c0.c1023 Target Objects [ tun_socket ] Source qemu-system-x86 Source Path /usr/bin/qemu-system-x86_64 Port <Unknown> Host (removed) Source RPM Packages qemu-system-x86-1.6.0-8.fc20.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-83.fc20.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 3.11.3-301.fc20.x86_64 #1 SMP Thu Oct 3 00:57:21 UTC 2013 x86_64 x86_64 Alert Count 1 First Seen 2013-10-07 19:04:31 EDT Last Seen 2013-10-07 19:04:31 EDT Local ID a137a3fd-1922-4b2d-ba88-b30cd8472aa0 Raw Audit Messages type=AVC msg=audit(1381187071.716:2194): avc: denied { attach_queue } for pid=27690 comm="qemu-system-x86" scontext=system_u:system_r:svirt_t:s0:c194,c501 tcontext=system_u:system_r:virtd_t:s0-s0:c0.c1023 tclass=tun_socket type=SYSCALL msg=audit(1381187071.716:2194): arch=x86_64 syscall=ioctl success=yes exit=0 a0=1e a1=400454d9 a2=7feb9926d850 a3=0 items=0 ppid=1 pid=27690 auid=4294967295 uid=107 gid=107 euid=107 suid=107 fsuid=107 egid=107 sgid=107 fsgid=107 ses=4294967295 tty=(none) comm=qemu-system-x86 exe=/usr/bin/qemu-system-x86_64 subj=system_u:system_r:svirt_t:s0:c194,c501 key=(null) Hash: qemu-system-x86,svirt_t,virtd_t,tun_socket,attach_queue Additional info: reporter: libreport-2.1.7 hashmarkername: setroubleshoot kernel: 3.11.3-301.fc20.x86_64 type: libreport
