[WSL1] [glibc] sleep: cannot read realtime clock: Invalid argument #4898

hferreira23 · 2020-02-14T21:13:35Z

Windows build number: Microsoft Windows [Version 10.0.18362.592]
WSL version: 1
Linux distro: Arch WSL

Description:

I'm using Arch WSL in WSL 1 and after an update which bumped glibc from 2.30.3 to 2.31.1 the sleep command stopped working throwing out the error: sleep: cannot read realtime clock: Invalid argument

This affects namely as Ansible, as ansible runs sleep commands in multiple modules. In this issue, on the Arch WSL github (yuk7/ArchWSL#108) , some problems with rust packages were also identified.

Downgrading to the previous version solves the issue. Now, I know that Arch WSL is not an official WSL implementation but this may actually happen when Ubuntu, etc, reach the aforementioned version of glibc

sirredbeard · 2020-02-14T23:04:22Z

Guidance on this issue in Ubuntu on WSL1 is here: https://discourse.ubuntu.com/t/ubuntu-20-04-and-wsl-1/15291:

What is the plan?

For WSL 1 users, I recommend you sit tight on Ubuntu 18.04 for now. The patch for issue 4989 will take some time to be backported. Ubuntu 18.04 is an LTS release, short for long-term servicing, and is supported through 2023 so you will continue to get security patches and backports from Canonical in the meantime.

Workarounds include:

holding libc6 before upgrading: [WSL1] [glibc] sleep: cannot read realtime clock: Invalid argument #4898 (comment)
adding this PPA: [WSL1] [glibc] sleep: cannot read realtime clock: Invalid argument #4898 (comment)

If you need to reset Ubuntu and are on WSL 1, you should switch to the Ubuntu 18.04 image.

I can confirm upgrading glibc from 2.30.3 to 2.31.1 on Arch on WSL breaks sleep.

I used the Arch rootfs from the ArchWSL project: https://github.com/yuk7/ArchWSL/releases/download/20.2.7.0/Arch.zip

Imported it.

Confirmed 2.20.3 installed:

$ pacman -Q --info glibc

In /etc/pacman.conf changed SigLevel= to Never.

Ran updates:

$ pacman -Syu

Confirmed new version:

$ pacman -Q --info glibc

Tried $ sleep 10. Got came error.

strace attached.
sleep10.txt

sirredbeard · 2020-02-15T01:17:50Z

It looks like sleep used to call:

nanosleep({tv_sec=10, tv_nsec=0}, NULL) = 0

sleep10-glibc2.30-3.txt

Appears that support for nanosleep was added in 14915.

But now calls:

clock_nanosleep(CLOCK_REALTIME, 0, {tv_sec=10, tv_nsec=0}, NULL)

sleep10-glibc2.31-1.txt

The line in sleep is here: https://github.com/coreutils/coreutils/blob/master/src/sleep.c#L142

if (xnanosleep (seconds))

Here are the release notes for glibc 2.31.1, they mention some changes related to clock issues but nothing jumps out as directly related: https://sourceware.org/ml/libc-announce/2020/msg00001.html

Also this may all technically be a duplicate of #2503

therealkenc · 2020-02-15T03:02:52Z

Also this may all technically be a duplicate of #2503

Most def. Apologies I saw this submission and knew it was dupe #2503 earlier in the afternoon, but got pulled away before I could hit the button. Thanks for going down the rabbit hole.

I'll forward-dupe #2503 as a (probably bad precedent) bump. If this is in glibc it'll hit distros in the store soon enough. Presumably eating CLOCK_REALTIME but providing CLOCK_MONOTONIC semantics in the WSL1 driver would be a pretty small change.

sirredbeard · 2020-02-15T03:05:52Z

Between glibc 2.30 and 2.31 they add the following to /posix/nanosleep.c:

{
  int ret = __clock_nanosleep (CLOCK_REALTIME, 0, requested_time, remaining);
  if (ret != 0)
    {
      __set_errno (ret);
      return -1;
    }
  return 0;
}

therealkenc · 2020-02-15T03:11:04Z

Right, this.

sirredbeard · 2020-02-15T03:14:19Z

Here an interesting related email thread:

POSIX.1 specifies that nanosleep() should measure time against the
   CLOCK_REALTIME clock.

therealkenc · 2020-02-15T03:20:06Z

Yeah. Ref.

dbz2k · 2020-02-15T15:18:16Z

I was wondering would issues like these get backported to with cumulative updates, or I would I have to wait till the next window version.

sirredbeard · 2020-02-15T20:57:34Z

I spoke with one of the senior engineers on our foundations team and they do plan to land glibc 2.31, with the problematic change, in Ubuntu Focal 20.04, our next release in April.

This one would be a useful to have backported unless it can be fixed upstream.

dbz2k · 2020-02-24T04:42:40Z

sorry for commenting again I was wondering if there were going to have wait till the next window version to get it fixed?

SvenGroot · 2020-02-27T21:56:02Z

As @therealkenc surmised, the issue is the lack of CLOCK_REALTIME support in WSL1's clock_nanosleep. We have a fix working internally, which will make its way to insiders. We will also look into backporting this to older Windows versions, but I can't make any promises or provide a timeline for this, unfortunately.

kailiu42 · 2020-03-02T04:22:34Z

I believe this is the problem that caused 100% CPU utilization on a single core for the cron process on my system. It used to run well until a few days ago the cron daemon process suddenly always on 100% CPU core usage. I checked my system it indeed has glibc upgraded to 2.31 on Feb 20. Then I straced cron process, it keeps calling clock_nanosleep(CLOCK_REALTIME, ...) indefinitely, might be the problem that caused high CPU utilization.

ChrisTX · 2020-03-06T00:19:39Z

I've gotten 2.31 to work fine on my Arch install by recompiling the package with a patch to __clock_nanosleep replacing CLOCK_REALTIME with CLOCK_MONOTONIC:

Close. You've got to be careful about TIMER_ABSTIME in flags. A straight-up swap of CLOCK_REALTIME for CLOCK_MONOTONIC probably isn't (quite) enough. [This is possibly academic for the quick fix; no one sane uses TIMER_ABSTIME. It might not even matter IRL, it would take some test cases to confirm.]

That's a valid point, but clock_nanosleep(CLOCK_REALTIME, ...) has always been broken on WSL, and that includes with TIMER_ABSTIME. It's easily fixable by subtracting the current CLOCK_REALTIME value from the absolute timestamp and dropping the TIMER_ABSTIME flag. I've expanded the patch to that end, but I really doubt this has any practical impact or use. I've uploaded the patch as a Gist.

Of course this is not a fix and I think I did it worse: all calls to sleep will fail. But it was fun and Ubuntu WSL1 is not my main driver so I had nothing to lose ;)

Will this be fixed for WSL1 or we can only count on WSL2?

The latest build of Ubuntu 20.04 seems to be working fine without any issue in WSL1.

@Kraml A fix is coming to WSL1, and we're looking into backporting it to currently released Windows versions.

escape0707 · 2020-07-17T15:47:48Z

Just for reference, here's what I did on Arch WSL to downgrade glibc for now.

I was getting horrendous CPU usage in VSCode's remote WSL due to sleep not working beforehand.
wget 'https://archive.archlinux.org/packages/g/glibc/glibc-2.30-3-x86_64.pkg.tar.xz'
pacman -U glibc-2.30-3-x86_64.pkg.tar.xz
Then in /etc/pacman.conf:
HoldPkg     = glibc

Simply do:

pacman -U https://archive.archlinux.org/packages/g/glibc/glibc-2.30-3-x86_64.pkg.tar.xz

... as it will let pacman also automatically download the package's detached .sig file and verify it according to /etc/pacman.conf settings.

And do you mean IgnorePkg = glibc ?

P.S. There should also be a default value fakeroot put by its side.

Kynolin · 2020-07-18T16:40:52Z

I think I glanced at the wrong line when I added my comment, but I can't remember which was one already in there. Here's what those lines are currently set to in my pacman.conf. I updated my original comment to clarify. Thanks.

HoldPkg     = pacman glibc
IgnorePkg   = fakeroot glibc

I ran into the same problem, and this procedure from this bug report fixed it:

Edit /var/lib/dpkg/info/libc6\:amd64.postinst

and comment out the line

# set -e

so $ apt-get -f install can continue.

I am using this solution #4898 (comment) for a month. No trouble and much easier/secure.

jiucenglou · 2020-08-04T02:52:32Z

I prefer this solution, it seems less invasive than installing a patched glibc.

Create this file called nanosleep.c
#include <time.h>
#include <unistd.h>

# gcc -shared -fPIC -o /usr/local/lib/libnanosleep.so nanosleep.c
# echo /usr/local/lib/libnanosleep.so >> /etc/ld.so.preload

I verified this fixes sleep and htop for me.

@jiucenglou If you want to compile some C or C++, them install at least the "build-essential" ubuntu/debian meta package. Save this hint in your knowledge base.

build-essential is sufficient to compile nanosleep.c tiny C code.

CaliforniaMountainSnake · 2020-08-21T12:41:11Z

I have this problem on Ubuntu 20.04 from windows store, but not on Ubuntu 18.04. Debian also works fine.

escape0707 · 2020-08-22T14:44:29Z

mask your glibc version for package manager, keep it in version 2.30. it's different in different distribution, for Arch Linux, add glibc to IgnorePkg in /etc/pacman.conf, I don't know whether this will cause some version confliction, but for Arch Linux, nothing crash till today.

This is actually causing two problems on ArchWSL for me now:

The first is this old glibc blocks libxcrypt update. Because libxcrypt owns /usr/include/crypt.h /usr/lib/libcrypt.so now.
The second is that when I'm still on old glibc and didn't do any update, I can no longer use vscode-python renaming.

Any suggestions?

Seems like your systemd is too new, and it requires updated glibc or libxcrypt. But I’m not very sure as well...

Errors were encountered while processing:
 libc6:amd64
E: Sub-process /usr/bin/dpkg returned an error code (1)

I "fixed" it somehow on my install. Because the error is in the postinstall script of libc6 package, I simply edited /var/lib/dpkg/info/libc6:amd64.postinst and transformed "sleep 1" in "echo sleep 1".
Then I run, as advised, 'apt --fix-broken install' and it managed to fix the dependencies. I removed then my change to the post-install script. "apt update" and "apt full-upgrade" seems to be working fine after that.
Of course this is not a fix and I think I did it worse: all calls to sleep will fail. But it was fun and Ubuntu WSL1 is not my main driver so I had nothing to lose ;)

Worked fine but it stops package manager to upgrade 3 packages to their previous state. But glad it worked...

@hellohackie : Thanks for your workaround, now let me expand on that.. You can work around this even more by installing busybox-static and using:

alias sleep='busybox sleep '

Observe:

I prefer this solution, it seems less invasive than installing a patched glibc.

Create this file called nanosleep.c

#include <time.h>
#include <unistd.h>

// This restores the old behaviour of nanosleep() to use CLOCK_MONOTONIC.
//
// "POSIX.1 specifies that nanosleep() should measure time against the
// CLOCK_REALTIME clock. However, Linux measures the time using the
// CLOCK_MONOTONIC clock.  This probably does not matter [...]"
//
// # gcc -shared -fPIC -o /usr/local/lib/libnanosleep.so nanosleep.c
// # echo /usr/local/lib/libnanosleep.so >> /etc/ld.so.preload
//
int nanosleep(const struct timespec *req, struct timespec *rem)
{
    return clock_nanosleep(CLOCK_MONOTONIC, 0, req, rem);
}

int usleep(useconds_t usec)
{
    struct timespec req = {
        .tv_sec     = (usec / 1000000),
        .tv_nsec    = (usec % 1000000) * 1000,
    };
    return nanosleep(&req, NULL);
}

# gcc -shared -fPIC -o /usr/local/lib/libnanosleep.so nanosleep.c
# echo /usr/local/lib/libnanosleep.so >> /etc/ld.so.preload

I verified this fixes sleep and htop for me.

last line didn't work for me, but changing the command a bit, and worked!
here it is:

sudo sh -c "echo /usr/local/lib/libnanosleep.so >> /etc/ld.so.preload"

This issue is fixed for Insiders in the Beta channel and the Release Preview channel with 20H2 Build 19042.487 (KB4571744). I would recommend reversing any custom changes to your WSL once you've updated.
