[Bug 423252] Re: NSS using LDAP+SSL breaks setuid applications like su, sudo, apache2 suexec, and atd
According to Andreas Metzler
http://lists.debian.org/debian-legal/2011/02/msg6.html
{{ GnuTLS upstream has added support for different crypto backends in
2.11.x and has chosen nettle as prefered backend (2.10.x is using
libgcrypt). }}
I have started to experiment with using a gnutls26 package with nettle
instead of libgcrypt11 on Ubuntu 12.04.
I have yet to adjust the gnutls26 package dependencies, at this point
I just cheat and install nettle-dev manually:
sudo apt-get install nettle-dev
Then I
apt-get source gnutls26
to fetch the source for gnutls26-2.12.14
chop out
--with-libgcrypt
from debian/rules
bump the package version in debian/changelog to 2.12.14-5ubuntu2.1
and rebuild with
debuild -i -uc -us -b
then I put a checkpoint on the VM and install the package:
dpkg -i libgnutls26_2.12.14-5ubuntu2.1_amd64.deb
but then sudo works on my LDAP+SSL client.

[Bug 795717] Re: 32bit rhel and centos 5.(5|6) hangs on boot on natty
In comment #2
https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/795717/comments/2
gdahlman's observation:
{{ As an update I can boot when the guest is restricted to a single cpu ... }}
I think means that on the VM host if /usr/bin/kvm is forced to run on
only one CPU via setting its processor affinity (via /usr/bin/taskset
from the util-linux package) this issue does not occur. I can and will
test that too soon.
If it's true it explains a bit of why Ubuntu VM guests only sometime
hang. The /usr/bin/kvm process running them might only sometimes switch
CPUs while the VM guest is rebooting while /usr/bin/kvm running 32-bit
RHEL 5 with 2 CPUs might always switch CPUs while the VM guest is
rebooting.
Also of note, 64-bit RHEL 5 does not use kvm-clock as a clocksource.
For example:
64-bit RHEL 5
$ sudo cat /sys/devices/system/clocksource/clocksource0/available_clocksource
jiffies
32-bit RHEL 5
$ sudo cat /sys/devices/system/clocksource/clocksource0/available_clocksource
acpi_pm jiffies hpet tsc pit kvm-clock
Both x86 and x86_64 RHEL 6 use kvm-clock but also linux kernel 2.6.32
I think by not using kvm-clock 64-bit RHEL 5 is not 100% vulnerable the
way 32-bit RHEL 5 is.

[Bug 882579] Re: Some Commands return: Timed out during operation: cannot acquire state change lock
I've been able to narrow this down a little more. The number of VM guests is not a factor, this has happened on a VM host with only one guest. The VM guest kernel does not seem to matter either, even VM guests which are Linux distros other than Ubuntu are affected. It seems that the /usr/bin/kvm process goes into an infinite loop during VM guest shutdown. I'm still investigating this further. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in Ubuntu. https://bugs.launchpad.net/bugs/882579 Title: Some Commands return: Timed out during operation: cannot acquire state change lock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/882579/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 882579] [NEW] Some Commands return: Timed out during operation: cannot acquire state change lock
Public bug reported:
While attempting to use virsh commands this error occurs:
Oct 27 08:52:22 boron libvirtd: 08:52:23.000: 25851: error :
qemuDomainObjBeginJobWithDriver:453 : Timed out during operation: cannot
acquire state change lock
While the error state is present certain commands like virsh shutdown
and virsh destroy elicit that error message and fail to work
completely I found that if I kill the kvm guest processes
$ kill -9 $(ps ax | grep '/usr/bin/kvm.*guestname' | awk '{print $1}')
Then virsh start guestname would work.
I'm not certain that the number of VM guests is the issue, however, this
happens more frequently to me on systems with larger numbers of guests.
We have one with 14 guests and another with 53.

[Bug 882579] Re: Some Commands return: Timed out during operation: cannot acquire state change lock
Today two VM hosts running kernel 2.6.38-11, one with with 14 guests and another with 53 had scheduled reboots of the many of their guests. On the VM host with 14 guests, 11 rebooted. On the one with 53 guests, 48 rebooted. VM guests that automatically rebooted this morning at 6:30 AM via at(8) hung instead of rebooted. All of the VM guests were rebooting from kernel 2.6.38-11 into 2.6.38-12 Not all of the VM guests on the hosts were scheduled to be rebooted. virsh shutdown and virsh destroy appeared to always hang. After using kill -9 on the PID of the VM guest virsh start for that guest worked every time. Initially on the VM hosts virsh list would output some VM names then hang. After enough VM guests were reset via kill -9 (but before all of them were) virsh list became able to run to completion. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in Ubuntu. https://bugs.launchpad.net/bugs/882579 Title: Some Commands return: Timed out during operation: cannot acquire state change lock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/882579/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Using kill -9 directly on the /usr/bin/kvm process of the hung VM guest that was using 100% CPU did restore the ability to use virsh start on the guest.

If you look at the last comment in the Red Hat bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=676205#c26
{{ 1. The QEMU process has hung.
QEMU won't respond to monitor commands. The API call making the first
monitor command will wait forever, any subsequent API calls issuing monitor
commands will timeout after ~30 seconds with this libvirt error message.
This is expected behaviour when QEMU has hung. }}
I think this might be the issue I am experiencing.

[Bug 882579] Re: Some Commands return: Timed out during operation: cannot acquire state change lock
I don't think virsh shutdown and virsh destroy are triggers. I think when the guest rebooted something went wrong and subsequent attempts to use virsh shutdown and virsh destroy fail. This morning the en-mass VM guest reboot was triggered by cron jobs inside the guests. I tried unsuccessfully to reproduce this on a VM host that only has a single VM guest. I'm still investigating if having several VM guests reboot at the same time is the trigger or not. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in Ubuntu. https://bugs.launchpad.net/bugs/882579 Title: Some Commands return: Timed out during operation: cannot acquire state change lock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/882579/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 229632] Re: ntpd should run niced
@Jamie given that the default ntpd configuration is to poll and the stability of the clock affects the polling interval[1] I would strongly suggest the default ntpd configuration be adjusted to run with the -N option since it would cut down on the load of NTP servers if polling was less frequent. When this scales to the world sizes it does become an issue. 1. In a nutshell when the clock is stable there is less need for ntpd to check to see the time on the upstream NTP server so it ratchets back the interval (decreases frequency) for polling by sleeping longer between checks. See ntp option maxpoll and minpoll in man ntp.conf to see the controls of the limits of the polling frequency range.

[Bug 229632] Re: ntpd should run niced
The minimum sleep time between ntpd upstream requests is 64 seconds. With 64000 clients an ntpd server must answer one thousand requests per second. If the client ntpd clocks are very stable they will ratchet back to one request every 1024 seconds (about 17 minutes) so the same 6400 clients would only make the server process 62.5 requests per second. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to ntp in Ubuntu. https://bugs.launchpad.net/bugs/229632 Title: ntpd should run niced To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntp/+bug/229632/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 229632] Re: ntpd should run niced
Try with and with out ntpd -N option. Use ntpq -p or ntpdc -c peers to view the polling interval. Both reports have a poll column which is the sleep time in seconds between requests being sent out over the network to the upstream NTP source. The poll column will eventually change from 64 to 128 then 256 through 1024. This change can take hours or even days to occur as the clock stabilizes. Without -N I haven't seen the polling interval get to 1024 on my systems as process preemption destabilizes ntpd too much. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to ntp in Ubuntu. https://bugs.launchpad.net/bugs/229632 Title: ntpd should run niced To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntp/+bug/229632/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

We are limited a single NTP upstream source due to political reasons outside our control and our Ubuntu ntpd loses sync periodically. I tried a number of solutions but they all failed. When I tried setting the ntpd server's nice value to negative eight it just works. Clearly the stability of ntpd is improved by reducing the number of cases in which ntpd gets preempted by scheduling. While troubleshooting this I started keeping logs with: while true ; do ntpq -p | grep name-of-upstream-time-source | logger -t ntpq -p daemon.info; done A pair of log entries showing loss of sync looks like: time remote refid st t when poll reach delay offset jitter === 2010-02-08:2010-02-08T21:53:00-05:00 *-.xxx.x 128.59.39.48 2 u 12 64 3770.5120.030 0.098 2010-02-08:2010-02-08T21:54:04-05:00 -.xxx.x 128.59.39.48 2 u 11 64 3770.5120.030 0.342 The * in the first entry indicates that the local Ubuntu host was synchronized to the remote host.

Jaunty uses a newer libgnutls option. The slapd.conf man page (and slapd-conf man page) still says you can find cipher names for TLSCipherSuite (and olcTLSCipherSuite) by running gnutls-cli -l but names output by that command are not accepted as options for TLSCipherSuite. This is a bug in the documentation. If you look through the libgnutls source code (file gnutls26-2.4.2/lib/gnutls_priority.c function gnutls_priority_init() ) reveals option names. As an example, this syntax is accepted by slapd if you use slapd.conf on Jaunty: TLSCipherSuite SECURE256:SECURE128 but OpenLDAP on Hardy could use TLSCipherSuite TLS_RSA_AES_256_CBC_SHA1:TLS_RSA_ARCFOUR_MD5 and now slapd on Jaunty will not start if you try that despite what the manual page says about TLSCipherSuite accepting ciphers that gnutls-cli -l outputs. -- Wrong documentation for TLSCipherSuite https://bugs.launchpad.net/bugs/317401 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openldap2.3 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

That is to say: TLSCipherSuite FOO works and TLSCipherSuite BAR works but TLSCipherSuite FOO:BAR results in slapd not starting up. -- Wrong documentation for TLSCipherSuite https://bugs.launchpad.net/bugs/317401 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openldap2.3 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Oops. Please close this as invalid. TLSCipherSuite is working with colon separated lists for me.
