Hi, I have a setup in which I run sshd as unprivileged user at dedicated port to serve specific application. It is working perfectly! One tweak I had to do, since the AuthorizedKeysCommand feature requires file to be owned by root, I had to use root owned command at root owned directory, although it does not add a security value. At auth2-pubkey.c...

Hi, I've problems to install printer drivers as a normal user with unprivileged rights on WinXP in a samba 3.0.24 domain (debian etch) using the "Point-and-Print" mechanism. I've read Volker Lendecke's Samba book on page 131 footnote 1, which mention to enable "point and print". Which reg keys do I have to set to install drivers by "Point and...

Hi, I'm having trouble rationalizing the behaviour described below. Is this a security-issue (bug) or a feature? - An unprivileged user 'bztest' with read-only access to /dev/ar0: %id uid=1004(bztest) gid=1004(test) groups=1004(test), 5(operator) %ls -l /dev/ar0 crw-r----- 1 root operator 4, 21 Nov 23 17:34 /dev/ar0 - Now, the device ar0 has the standard mbr installed: %cmp /dev/ar0 /boot/mbr /dev/ar0 /boot/...

Is there any way for unprivileged guests to map each others memory without grant tables? Now that the pressure is off for me to support SMP internally, I''d like to switch back to using -testing. Thanks. -Kip _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensou...

The libvirt LXC driver only runs in the privileged libvirtd instance at this time. There is no support for the unprivileged libvirtd with LXC.

Hi Marco, anybody, > + must be 'privileged' container (no unprivileged ones) I have seen containers with and without calling for being privileged, but you never know without trying and testing carefully... Googling I found https://github.com/lxc/lxd/issues/3442#issuecomment-312560949 but I am not really clear about the conclusion. Does it really have to be privilege...

We run unprivileged lxc containers (libvirt based) with next config: ... <idmap> <uid start='0' target='65535' count='65535'/> <gid start='0' target='65535' count='65535'/> </idmap> ... <devices> <emulator>/usr/libe...

...ak of time, so I'll try here. Here is a patch that I'm planing to commit: http://people.freebsd.org/~pjd/patches/restricted_hardlinks.patch It adds two new sysctls: security.bsd.hardlink_check_uid security.bsd.hardlink_check_gid If sysctl security.bsd.hardlink_check_uid is set to 1, unprivileged users are not permitted to create hard links to files not owned by them. If sysctl security.bsd.hardlink_check_gid is set to 1, unprivileged users are not permitted to create hard links to files if they are not member of file's group. For now user is able to create hardlinks to any files. -...

Dear all, I have set up one unprivileged Domain-1 with help of FedoraQuickStart and some help from you. Now I want to install some other OS to Domain-2. How can I install a different OS (say Redhat 7.3) onto a unprivileged domain? Do I have to copy all files from an existed installation to an image file? Thanks, Koala ______________...

Hello all, tl;dr, can you point me to the point in the libvirt repo where it's trying to change a tap-device's SELinux label? I am trying to create a tap device with libvirt on a super-privileged container, and then use it on another, unprivileged container with libvirt. User wise, I know I need the super-privileged container to open the tap device with the user of the unprivileged one - that I already did and it's not the issue. But I have a problem when I open the tap device in the non-privileged container: the tap device currently h...

Thanks for info about that. This means to use apparmor mandatory, isn't it true?
