The ARM runtime reports the major device type associated with
/proc/self/mountinfo as MMC_BLOCK_MAJOR, causing on_ssd() in

It needs to wait with libudev until the network devices it is interested

Thank you Tom and Lennart. I'm not sure what to call my network
configuration system. It's default Gentoo stuff, just initscrips in
runlevels. To confirm, I should file a Gentoo bug?
Are you using dhcpcd with this device? It's USE=udev in Gentoo that
makes net-misc/dhcpcd link against libudev
for initialization to make sure it's ready.
And this networking system is called net-misc/netifrc:
https://git.overlays.gentoo.org/gitweb/?p=proj/netifrc.git;a=summary
It's not programmed in C, so it's not using libudev, however, there is
/etc/init.d/net.lo that is part of the net-misc/netifrc
package, and net.lo has sys-apps/openrc specific depend() { } section,
so it's very much possible that net.lo init
script should have dependency on /etc/init.d/udev init script to ensure
it's initialized early enough
I suppose this could be the problem if you are not using dhcpcd, or it's
built wrongly, without USE=udev
So yeah, file a Gentoo bug and provide necessary information there, if
this didn't help you

Those other checks are not reached, as the beginning of fs_on_ssd() has
if (major(st.st_dev) == 0) {}
encapsulating them, and major(st.st_dev)=MMC_BLOCK_MAJOR, not 0.My first
attempt to fix the problem was
+if (streq(opts, mmc) || startswith(opts, mmc,) || endswith(opts,
,mmc) || strstr(opts, ,mmc,))
but that statement is also not reached. Likely the best practice is also to
compare MTD_BLOCK_MAJOR, but since I have no simple way to test that case, I
didn't include it. That's why I put the change inside an #ifdef. As Auke
points out in systemd-commits, where I erroneously attempted to post this
patch, any arch using an MMC would consider it non-rotational.

The problem occurs when a rshd (socket activated) execution is completed, the network connection is down and systemd is closing the socket. This causes a long (60 seconds) freeze where it's not possible to communicate with systemd. Do you have any idea on what is causing this or how we can investigate this further? To reproduce the problem: 1) Get latest Arch Linux 2) On remote machine execute rsh $target_ip -l root 'sleep 40' 3) Set link down on the interface which is assigned with $target_ip, on systemd machine ip link set down dev $if 4) On systemd machine, wait for 'sleep 40' to be completed. Then execute any systemd command systemctl list-jobs 5) After 60 seconds systemd is responding again By looking at the stack trace (see bellow), one can see that we are trying to close a socket and waiting on a system close call. So it's probably not a systemd problem, however systemd is affected by it. We've succesfully reproduced the problem on different hardware architectures (x86_64, arm, cris), systemd versions (208, 210, 212) and rshd implementations (netkit-rsh-0.17, inetutils 1.9.2-1). The problem occurs not only when the interface's link is set down, also when the IP address is removed or the ethernet cable is unplugged. ssh seems not to be affected by the problem. We generated a core dump: kill -SIGABRT 1 Here is the stack trace (the machine is running systemd 210).

[systemd-devel] cryptsetup vs. swapon/fsck (some kind of race condition)
-BEGIN PGP SIGNED MESSAGE- Hash: SHA512 Hi all, first I hope I'm asking at the right place here, if not feel free to kick me in the right direction. Now, for my problem: I have several encrypted partions set up via /etc/crypttab Since the update to systemd-212 (from 207 I think) the following happens - - Oh, here is a partition from crypttab, lets uncrypt it - - Crypto for /home done - - Hey, this block device for /home just turned up, lets fsck it - - Stopping crypto for /home (WTF? why would you do that?) - - Surprise fsck'ing the home partition failed because the device just disappeared I'm pretty sure it is some kind of race-condition/ timing problem, because about 1 in 10 boots works just fine. Also, the same setup worked fine before. I've been kind of living with this for a while now (login at the admin-shell and systemctl isolate default.target -- system goes up normally) because I was to lazy to dig through the logs, but today I finally got fed up enough with it to get of my lazy but. Sadly the logs didn't tell me much of *why* things happen the way they do, so maybe someone here as an idea how to investigate this further.

Hey list, I've create socket-activated user-mode unit[1] that sets up a SSH tunnel, but it fails to start because ssh is unaware of ssh-agent (gnome-keyring) because of empty environment.

Not following here. fs_on_ssd() will actually check for the high-level
ID_SSD property, as well as the queue/rotational sysfs attribute for
the block device.
Those other checks are not reached, as the beginning of fs_on_ssd() has
if (major(st.st_dev) == 0) {}
encapsulating them, and major(st.st_dev)=MMC_BLOCK_MAJOR, not 0.
No, those other checks are *below* the if.
What do
1. udevadm info /dev/mmcXXX | grep SSD
2. cat /sys/class/block/mmcXXX/queue/rotational
say?

Hi,
We stumbled upon a freeze/block in systemd.
The problem occurs when a rshd (socket activated) execution is
completed, the network connection is down and systemd is closing the socket.
This causes a long (60 seconds) freeze where it's not possible to
communicate with systemd.
Do you have any idea on what is causing this or how we can investigate
this further?
Can you check if this patch fixes the problem:

[systemd-devel] remounting root fs outside containers as MS_SHARED
Note: I had sent this email earlier but I realized that I needed to be subscribed to the mailing list. Now that I have my subscription, I am resending it again. Lennart, sorry for the double noise. --- Hello folks: The following change started mounting the rootfs as shared : b3ac5f8cb98757416d8660023d6564a7c411f0a0 The commit log and the corresponding comment in the code says that if any setups needed the kernel default private mount, one could use something like : mount --make-rprivate / right after the boot. Unfortunately, we have a setup where we do need the kernel default private mount and we tried what has been suggested by using a systemd service file to remount rootfs to private. Unfortunately, while this works most of the time, this technique is not bullet proof. Unfortunately glibc (and possibly other libraries) do telinit u as a part of their post installation setup. This re-execs systemd and hence remounts the root fs as shared again, breaking our system in the process. As it is not possible to go and fix all these libraries, I have a simple request from the systemd hackers here. Can we please have a configuration option (either as a kernel command line, or a systemd startup command line or a config file option) that disables this default behaviour for setups that do need the private rootfs mount? That way the default remains as is for most systems and yet there will be a way to override this when one really wants to. It would seem to give us the best of both worlds. Any comments?

I don't think this is a big deal so we could log this only if debug is on. To make sure if it is the case can you try to reproduce with systemd and logind debug turned on. Thanks! Heh. Reproducing was an interesting problem.

That would be it! As you can see [0] we proceed in execution of handler code for Abandon() only for scopes which are either running or already abandoned. However scope here is, at the time systemd gets to processing D-Bus request, already in a dead state. I'll wait a bit and if no one objects I'll go ahead and change log level for a message and also change it to something more sensible so it actually makes sense to people.
