[Bug 1890672] Re: secure boot fails after upgrade to grub2-common 2.04-1ubuntu26.2
ok, can i at least assume that shim is not required? that was my main issue. i wanted a single unencrypted file (grub + initramfs by another name:), and, my chain of trust. that is the key for me, if there is a requirement to only use shim and the microsoft keys, i'm in trouble. if its simply that canonical doesn't test w/o shim, that's ok. But it seems empirically that shim is now a hard requirement since the valid signed kernel no longer validates w/ this patch of grub. i guess also to the original bug from the original author here, perhaps removing the no-longer-supported option from grub doc would be good? the set check_signatures=no -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1890672 Title: secure boot fails after upgrade to grub2-common 2.04-1ubuntu26.2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1890672/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1890672] Re: secure boot fails after upgrade to grub2-common 2.04-1ubuntu26.2
I'm the author of that secure boot package. I think you might misunderstand... what it does is put all the grub config etc into a signed initramfs. So you cannot change the grub.cfg. Also, to sign the binaries you need the GPG keyring and the passphrase. The objective is to *not* use the shipped trusted microsoft key. The only key in the UEFI keystore is our own chain of trust. So The goal is to *not* use shim. It is used in conjunction w/ full disk encryption. The only file unencrypted is a single grub w/ the ininitramfs, and that is in turn signed. The kernel, etc, are all on the encrypted disk. Thus they cannot be tampered with by e.g. removing the disk etc. Installing shim means adding someone else trust, which I don't accept. I'm not sure what "don't support secure boot without shim" means, but I don't think that can or should be true. It doesn't support booting the Microsoft signed keys w/o shim, but, its certainly legal to remove the Microsoft keys from the BIOS and still use secureboot. as for the check_signatures=no, I'm ok if that is removed as a feature I guess, but it would need to be removed from the documentation. In my case its not a reduction in security (since you cannot change the grub.cfg w/o having the trust chain anyway). so tldr: * no, shim is not required to support secureboot * yes, you can self sign securely * no, merely having an option in grub.cfg or grub cmdline to disable subsequent checks need not reduce the security, as long as it is gated by being in a signed initramfs (and grub password is as strong as bios password) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1890672 Title: secure boot fails after upgrade to grub2-common 2.04-1ubuntu26.2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1890672/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1397130] Re: libvirt-bin crashes / refuses to restart if cgmanager is restarted
so part of the issue is cgm_* is not thread safe, but is called from various
threads.
e.g. if u start libvirtd w/ several instances already running, it will call
cgm_dbus_connect from each.
there is a pair of global variable:
static NihDBusProxy *cgroup_manager = NULL;
bool cgm_running = false;
in src/util/cgmanager.c, and they cause this issue.
cgm_dbus_connect() overwrites cgroup_manager regardless of the state of
cgm_running (and cgm_running is set @ the end of it anyway).
The use of pthread_once is probably part of the solution. The below
patch partially corrects.

OK, that is the problem.

it in turn assigns 'cgroup_manager'.

[Bug 1397130] Re: libvirt-bin crashes / refuses to restart if cgmanager is restarted
another way to reproduce this is to start new instances quickly (e.g.
create back to back), and then restart libvirt-bin.
and sometimes, just start new instances quickly (w/o restart libvirt-
bin)
for example, for host X, if the sleep are commented out, it will
normally crash libvirt if this is run to try and rescue the old
instances. if the sleep is present it will normally not crash.
#!/bin/bash
host=$1
j=0

Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. process 18397: The last reference on a connection was dropped without closing the connection. This is a bug in an application. See dbus_connection_unref() documentation for details. Most likely, the application was supposed to call dbus_connection_close(), since this is a private connection.
