Also, libreport does not detect GNOME 3 system-wide proxy settings for submitting bug reports to Bugzilla. :) I should probably enter that as a new bug. So you image is installed on a fat file system? Sure enough: /dev/sdb1 on /run/media/derekm/LIVE type vfat (rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0077,codepage=437,iocharset=ascii,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2) File is "en_windows_7_ultimate_with_sp1_x64_dvd_u_677332.iso" Do you have the virt_use_usb boolean turned on? ff1e3933b46537f258292e95708b5cd78ec7ba74 fixes this in git. No, I haven't explicitly set anything with setsebool. This install is brand new and pretty much virgin/stock. Ok turn that boolean on and see if everything works. It will still have a the AVC, but I want to know if you see any other problems. # setsebool -P virt_use_usb 1 Back ported. selinux-policy-3.12.1-74.1.fc19 has been submitted as an update for Fedora 19. https://admin.fedoraproject.org/updates/selinux-policy-3.12.1-74.1.fc19 Package selinux-policy-3.12.1-74.1.fc19: * should fix your issue, * was pushed to the Fedora 19 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing selinux-policy-3.12.1-74.1.fc19' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2013-15819/selinux-policy-3.12.1-74.1.fc19 then log in and leave karma (feedback). selinux-policy-3.12.1-74.1.fc19 has been pushed to the Fedora 19 stable repository. If problems still persist, please make note of it in this bug report. I saw the update come thru so I tested the "setsebool -P virt_use_usb 1" solution prior to update, it did not work, still got the getattr error. Undid bool operation with "setsebool -P virt_use_usb 0" and installed new selinux-policy-3.12.1-74.1.fc19.noarch, ejected and reinserted USB thumbdrive, reopened GNOME Boxes, and now I get 'Connection to "_name_of_vm_" failed'. Do I need to reboot/relabel or something? Thanks! Sorry, I reset "setsebool -P virt_use_usb 1" and now it appears to be working without the getattr warning. I don't know whether virt_use_usb defaults to 0 or 1, but with it set to 0 it was failing on "open", with it set to 1 there is no longer an issue with "getattr". Thanks again! |
Description of problem: Used GNOME Boxes to create a VM with installation ISO on USB media. SELinux is preventing /usr/bin/qemu-system-x86_64 from 'getattr' accesses on the filesystem /run/media/derekm/LIVE. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that qemu-system-x86_64 should be allowed getattr access on the LIVE filesystem 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 unconfined_u:system_r:svirt_t:s0:c530,c772 Target Context system_u:object_r:dosfs_t:s0 Target Objects /run/media/derekm/LIVE [ filesystem ] Source qemu-system-x86 Source Path /usr/bin/qemu-system-x86_64 Port <Unknown> Host (removed) Source RPM Packages qemu-system-x86-1.4.2-7.fc19.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-71.fc19.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.10.9-200.fc19.x86_64 #1 SMP Wed Aug 21 19:27:58 UTC 2013 x86_64 x86_64 Alert Count 1 First Seen 2013-08-23 11:18:40 CDT Last Seen 2013-08-23 11:18:40 CDT Local ID 829e88de-e54e-4e68-ac6c-d9f0e86f6938 Raw Audit Messages type=AVC msg=audit(1377274720.61:578): avc: denied { getattr } for pid=7875 comm="qemu-system-x86" name="/" dev="sdb1" ino=1 scontext=unconfined_u:system_r:svirt_t:s0:c530,c772 tcontext=system_u:object_r:dosfs_t:s0 tclass=filesystem type=SYSCALL msg=audit(1377274720.61:578): arch=x86_64 syscall=fstatfs success=no exit=EACCES a0=10 a1=7fffda9a6a50 a2=0 a3=1 items=0 ppid=1 pid=7875 auid=1000 uid=1000 gid=1000 euid=1000 suid=1000 fsuid=1000 egid=1000 sgid=1000 fsgid=1000 ses=1 tty=(none) comm=qemu-system-x86 exe=/usr/bin/qemu-system-x86_64 subj=unconfined_u:system_r:svirt_t:s0:c530,c772 key=(null) Hash: qemu-system-x86,svirt_t,dosfs_t,filesystem,getattr Additional info: reporter: libreport-2.1.6 hashmarkername: setroubleshoot kernel: 3.10.9-200.fc19.x86_64 type: libreport
