Description Michal Konecny 2025-02-20 10:36:51 UTC

After update of gnutls today (20.02.2025) on our builder VM host in Fedora Infrastructure the NetworkManager failed to start with issue when importing gnutls library.

After downgrading to gnutls-3.8.8-3.fc41.ppc64le it started working fine again.

Reproducible: Always

Steps to Reproduce:
1. Update to gnutls-3.8.9-2.fc41.src.rpm
2. Restart machine
Actual Results:  
NetworkManager fails to start

Expected Results:  
NetworkManager is running

Comment 1 Alexander Sosedkin 2025-02-20 10:47:34 UTC

... cannot reproduce on x86_64, will try on ppc64le. What's the error, by the way?

Comment 2 Michal Konecny 2025-02-20 11:03:56 UTC

Forgot to add the actual error:

```
Feb 20 10:13:28 bvmhost-p09-04.iad2.fedoraproject.org NetworkManager[6041]: /usr/sbin/NetworkManager: error while loading shared libraries: /lib64/libgnutls.so.30: file too short
```

We have a dnf automatic script setup on our machines and I noticed only this one ppc64le misbehaving like that.

Comment 3 Alexander Sosedkin 2025-02-20 12:10:19 UTC

That's purely vibes-only analysis at this point, but smells like data corruption to me.
The following diagnostics steps might prove useful in either confirming or denying this:

sha256sum /lib64/libgnutls.so.30
wc -c /lib64/libgnutls.so.30
rpm -V gnutls

Comment 4 Alexander Sosedkin 2025-02-20 12:35:22 UTC

... got a ppc64le, and yes, cannot reproduce:

# rpm -q gnutls
gnutls-3.8.9-2.fc41.ppc64le
# systemctl restart NetworkManager
# sha256sum /lib64/libgnutls.so.30
c82003a1afa8a84d7c8dc5a197b0d4d37f4502111764c5db402b4b78a87eeb49  /lib64/libgnutls.so.30
# wc -c /lib64/libgnutls.so.30
2866664 /lib64/libgnutls.so.30
# rpm -V gnutls && echo OK
OK

unless I manually truncate the shared library:

# :>/lib64/libgnutls.so.30
# sha256sum /lib64/libgnutls.so.30
e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855  /lib64/libgnutls.so.30
# wc -c /lib64/libgnutls.so.30
0 /lib64/libgnutls.so.30
# rpm -V gnutls
S.5....T.    /usr/lib64/libgnutls.so.30.40.3
# systemctl restart NetworkManager
Job for NetworkManager.service failed because the control process exited with error code.
See "systemctl status NetworkManager.service" and "journalctl -xeu NetworkManager.service" for details.
[root@ibm-p10-01-lp65 ~]# journalctl -u NetworkManager|grep short
Feb 20 07:30:03 *redacted* NetworkManager[2220]: /usr/sbin/NetworkManager: error while loading shared libraries: /lib64/libgnutls.so.30: file too short
...
# dnf -y reinstall gnutls
# systemctl restart NetworkManager

Sorry to be the bearer of bad news, but please double-check the health of this machines partition and/or disk.

Comment 5 Michal Konecny 2025-02-20 14:27:51 UTC

Disk corruption is possible, we have another ppc63le machine that started to have problems with disks and they are same age as this one. Thanks for your time.
