Bug#977245: openssh-server: Kernel error after big rsync or scp
Package: openssh-server
Version: 1:8.4p1-3
Severity: important
X-Debbugs-Cc: jgmanilla@yahoo.com
Dear Maintainer,
After attempting to scp or rsync a directory with many large-ish files
(20-600M) to a remote host, the remote machine will crash. This hasn't happened
with smaller file transfers; only when the directory contains gigabytes of
data, after about 3GB have been copied. I tried once to scp a similar ammount
of data from a different client to the same machine, with the same result. The
commands used were:
scp -r ./localdirectory jgmanilla@remotehost:~/
rsync -avP ./localdirectory jgmanilla@remotehost:~/
If you happened to be logged into an ssh session, you may get the following
message before the system goes down:
Message from syslogd@localhost at Dec 12 16:22:24 ...
kernel:[ 406.101940] Internal error: Oops: 96000004 [#1] SMP
Message from syslogd@localhost at Dec 12 16:22:24 ...
kernel:[ 406.130105] Code: b9402a62 f9405e63 8b020014 dac00e81 (f8626814)
Expected outcome was for scp and rsync to complete their file transfers
with no errors.
The hardware of the remote machine was a RockPro64.
The client operating systems tested were Gentoo and Arch linux.
