Who's playing with scaling_max_freq?
Max scaling_max_freq seems stuck at 1GHz even though it should be able to go up to 1.83GHz. # echo 1833000 >/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq; cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 100 # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies 1833000 1333000 100 # This is on a Thinkpad T60 running Debian stable. Any idea what might be causing this? Or at least, which part of the system might cause scaling_max_freq to be (re)set to 1GHz right after I force-set it to 1.83GHz? Would it be some daemon like systemd or rather than kernel? This Thinkpad T60 is actually used as a desktop: it's parked in a dock (with the lid is closed) where I have it connected to a keyboard and monitor. Stefan

Looks more-or-less the same as previous attempt. Moreover,
open("/etc/group+", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 5
umask(022) = 0777
fchown(5, 0, 0) = 0
fchmod(5, 0644) = 0
fstat(5, {st_mode=S_IFREG|0644, st_size=0, ...}) = 0
...
lstat("/etc/group", {st_mode=S_IFREG|0644, st_size=824, ...}) = 0
rename("/etc/group+", "/etc/group") = -1 EBUSY
lstat shows that both /etc/group and /etc/group+ are regular files.
For the sake of the purity of the experiment, it would be nice to reboot
the system with "init=/bin/sh" added to kernel commandline (to exclude
systemd interference), but I foresee that the result would be the same.
So, to sum it up. Your current kernel + root filesystem combo prevents
you to overwrite /etc/group (and I suspect any existing file) with
another file by means of conventional rename(2) syscall, which returns
anomalous return code.
My gut feeling tells me that one should blame filesystem (btrfs)
implementation in cases such as this.
This behavior justifies a bug report with severity 'serious' against

DD-WRT might be better for me as it's mostly pre-configured to make set up easier for a lowly tyro. At least, that's what I've been reading. B

Ok, then we'll have to do it hard way. Basically I want to make sure
that it's btrfs fault, not some mount output anomaly that hides
bind-mounted /etc/group.
unshare -m /bin/bash
mount -o bind / /mnt
mount -o bind /proc /mnt/proc
mount -o bind /dev /mnt/dev
chroot /mnt
strace groupadd -g 1234 test
exit
exit
'exit' should be done twice, first time to exit chroot, second time to
exit detached mount namespace.

apache 2.4.10, debian jessie, PHP 7.0.4 SWAP issue
Hello guys. We are experiencing weird issue when we implemented this new combination of debian+apache+PHP. The system is serving PHP pages. It is running correctly for a quite a bit and then start to heavily swap without any outer issue (no load spike). The swap is not cleaning itself, only apache restart is of help in this case. We were not experiencing this with combination of debian wheezy+apache 2.2.22+PHP 5.5.16. Do anybody have an idea where to look at? Thanks in advance. -- Marek Soha boberdoo.com ma...@boberdoo.com Skype: mareksoha Computer Science: solving today's problems tomorrow.
Re: Installation of openssh-client stops with error in groupadd
Hi,
as I restarted my computer today. I wanted to install lsof via apt-get
and at least it configured openssh-client without failure. So I thought
that problem fixed itself, but it didn't.
I tried to add another group manually so I typed as root:
# groupadd -g 1234 test
groupadd: failure while writing changes to /etc/group
and
# strace groupadd -g 1234 test
showed the known error:
...

Documentation starting point for your particular problem (systemd has a lot of man pages, and on Debian they are installed as part of the systemd package so should always be present): $ man systemd.unit $ man systemd.service You probably want to look at the 'After=' and 'Before=' directives, which can be used to say "unit A must not be started until after unit B has been successfully started, and unit A must be stopped before unit B can be stopped".
jessie systemd shutdown sequence
Hello all, I'd like to find out more about what the systemd does during shutdown/reboot. I knew pretty well what old sysVinit does, but my long experience is worthless with systemd, and I have to learn anything anew :(. I accept RTFM answers if they include links ;) The problem I have is partially related to https://bugs.debian.org/cgi- bin/bugreport.cgi?bug=751636 In my eyes it seems that systemd shuts down everything in parallel, including networking. So it can stop network quite early, before other services. Thus SSH connection just hangs, instead of proper disconnect. That can be solved by installling libpam-systemd - SSH session closes immediately after issuing reboot. However I would prefer, that SSH is not stopped until all other services shut down properly, so that if something goes wrong I can still connect and investigate or fix it. As an example - a virtual machine in libvirt/KVM/Qemu, that for whatever reason ignores the ACPI button, and does not shut down. Yeah systemd will kill it eventually (5 minutes or so), but I would prefer to log into such machine and issue correct shutdown. Unfortunately the neworking was gone at that moment. Another similar bug (hopefully fixed now), was that bind for some reason did not shut down on SIGINT/SIGTERM, and the init script was waiting forever. Without SSH stil active I would have to power cycle the server. (which is a bit more complicated with remote servers). So what I would like to achieve is to set somehow the dependencies in systemd, so that networking is deconfigured only after all services are stopped, and that SSH is the last service to stop. Perhaps this should be a bug report against systemd, but I wanted first to know if I'm not missing something that is obvious for those who know systemd better. -- Best Regards Vladislav Kurz
