This implements the --selinux-relabel option for virt-customize, virt-builder and virt-sysprep. There is no need to autorelabel functionality now.

Rewrite the relabel API to read the policy configured in the guest, invoking setfiles (added as part of the appliance, as part of policycoreutils) to relabel the specified root. In case of failure at any point of the process, a touch of .autorelabel in the root is tried as last-attempt measure to do the relabel. Considering that running SELinux tools in the appliance might be affected by the

the description of the --selinux-relabel option suggests that it perform an immediate relabel, when in fact it may (and probably will) instead simply touch /.autorelabel on the image, which schedules a relabel operation for the next time the image boots. This can be surprising because it results both in an extended initial boot time *and* results in an automatic reboot (on some distributions).

Do not attempt to relabel a guest in case its SELinux enforcing mode is not "enforcing", as it is either pointless, or it may fail because of an invalid policy configured. --- mlcustomize/SELinux_relabel.ml | 26 +++++++++++++++++++++++++- 1 file changed, 25 insertions(+), 1 deletion(-) diff --git a/mlcustomize/SELinux_relabel.ml b/mlcustomize/SELinux_relabel.ml index 647aeda..db00e59

[ I realized that we were discussing adding this feature, in various private email, IRC, and this long bugzilla thread: https://bugzilla.redhat.com/show_bug.cgi?id=1060423 That's not how we should do things. Let's discuss it on the mailing list. ] One thing that virt-customize/virt-sysprep/virt-builder have to do is relabel SELinux guests. What we do at the moment

A common problem that people have with virt-builder and virt-sysprep is which guests that use SELinux, like Fedora and RHEL. In both cases we touch /.autorelabel in the guest, which means the guest has to reboot once during its first boot. Recap: SELinux file labels -------------------------- SELinux requires that files have labels. Access to a file is controlled by the label on that file.

I'm trying to find a way to exclude file systems during the autorelabel process. I have a file system (/exports) that has tens of millions of files on it and I *know* I don't want it relabeled. I've tried semanage fcontext -a -t "<<none>>" "/exports(/.*)?" and it seems to insist on relabeling that file system. I also tried to see if there was a

Hello everyone, If create a folder called "whatever" under /var, the context is: root:object_r:var_t /var/whatever/ That's expected as it is under /var. If I then change its type: chcont -t httpd_sys_content_t /var/whatever The context looks like: root:object_r:httpd_sys_content_t /var/whatever/ My question is...Shouldn't a relabeling of the filesystem change the type

http://wiki.centos.org/HowTos/SELinux says: "Access is only allowed between similar types, so Apache running as httpd_t can read /var/www/html/index.html of type httpd_sys_content_t." however the doc doesn't define what "similar types" means. I assumed it just meant "beginning with the same prefix". However that can't be right because on my system with

If the guest uses SELinux, then make sure to run a relabel (or at least schedule one) after the image build: this way the template is relabelled, or at least it will do that at the next boot, without the need for the user to ask for a relabel. This just covers the case of building a new image with no additional operations on it though. --- builder/website/centos.sh | 2 ++

My home machine has IP 50.54.225.130. I have (for the purposes of this experiment) one remote machine at www.peacefire.org (69.72.177.140) and another at www.junkwhale.com. When I'm logged in to peacefire, I run this perl script to open an ssh connection to junkwhale and run a command: my $hostname="www.junkwhale.com"; my $server_password = "[redacted!]"; use Net::SFTP;

Continuation/rework of: https://www.redhat.com/archives/libguestfs/2020-May/msg00020.html This is my approach, as I explained here: https://bugzilla.redhat.com/show_bug.cgi?id=1828952#c4 https://www.redhat.com/archives/libguestfs/2020-May/msg00035.html IOW: do not attempt to relabel if the guest is not enforcing, as it is either useless or may fail; few words more are in the comments of patch #3.
