[Samba] segfault in smbclient 4.13.2?

[Joachim Lindenberg]

Hello,

 

As part of my replication script for sysvol, I am using the following excerpt:

 

mkdir /tmp/samba/sysvolcopy

cd /tmp/samba/sysvolcopy

peer='cobra.samba.lindenberg.one'

smbclient \\\\$peer\\sysvol 'password' -UJoachim -e --max-protocol SMB3  -c "prompt; recurse; mget *"

 

with 4.13.2-Debian running on Ubuntu 20.04 I get 

 

getting file \samba.lindenberg.one\Policies\{06C651B1-01BC-4B53-8497-40CFD30F94C2}\GPT.INI of size 59 as GPT.INI (0.6 KiloBytes/sec) (average 0.6 KiloBytes/sec)

./bug.sh: line 4:  3620 Segmentation fault      (core dumped) smbclient \\\\$peer\\sysvol 'password' -UJoachim -e --max-protocol SMB3 -c "prompt; recurse; mget *"

 

Whereas with 4.12.11 the script runs through all my sysvol successfully.

Is this a know bug in 4.13? An ACL issue? Anything else to check?

 

Thanks, Joachim
