libvirt-sandbox should not be launching these processes as svirt_t, unless they are truly virtual machines. Maybe we should launch all libvirt-sandbox processes as svirt_lxc_net_t, since they are going to need more access then svirt_t. Or I add a new type svirt_qemu_net_t, with close to the same policy. Yes, we need a svirt_qemu_net_t which extends svirt_t with the broader file read permissions from svirt_lxc_net_t. 477fa6894e2ed67512a4041a58fe6b858acd6573 adds svirt_qemu_net_t which is pretty much equivalent to svirt_lxc_net_t, one thing I have not changed is svirt_lxc_file_t to something like svirt_sandbox_file_t. It would make sense to change this, since we could then share the file type between the policies. Do you agree with this change? Having a common file type makes sense, but would renaming it cause upgrade problems ? It is possible to rename it, and keep a svirt_lxc_file_t type as an alias for svirt_sandbox_file_t for compatibility ? Yes. svirt_sandbox_file_t it is. Should be in selinux-policy-3.12.1-74.fc20 *** Bug 980542 has been marked as a duplicate of this bug. *** Is this fixed? I still have exactly this problem. This message is a notice that Fedora 19 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 19. It is Fedora's policy to close all bug reports from releases that are no longer maintained. Approximately 4 (four) weeks from now this bug will be closed as EOL if it remains open with a Fedora 'version' of '19'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 19 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
Description of problem: I tried to run virt-sandbox -c qemu:///session /bin/sh while having a confinged user in staff_u SELinux is preventing /usr/bin/qemu-system-x86_64 from 'read' accesses on the file mounts.cfg. ***** Plugin catchall (100. confidence) suggests *************************** If vous pensez que qemu-system-x86_64 devrait être autorisé à accéder read sur mounts.cfg file par défaut.
