Bug ID: 3714
Summary: sftp fails in one direction
Product: Portable OpenSSH
Version: 9.2p1
Hardware: ARM64
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: sftp
Assignee: unassigned-bugs at mindrot.org
Reporter: hp4everything at googlemail.com

--> https://bugzilla.mindrot.org/attachment.cgi?id=3827&action=edit
terminal messages client and server with option -vvvv
I have 2 Raspberry Pi with Debian-Linux
host1 Raspberry Pi3 with Linux 6.1.0-17-arm64
host2 Raspberry Pi4 with Linux 6.6.31+rpt-rpi-v8
On both the official openssh 9.2p1 with identical binaries
ssh works fine between both machines in both directions
sftp works fine with host2=client and host1=server
But sftp immediately closes the connection in the other direction!
In the error case there appear additional messages related to
pseudoterminals and a SIGCHILD-event is reported on the server.
Sorry, I'm not very familiar with pseudo-terminals. I've only read that
TIOCSCTTY might require special access rights (CAP_SYS_ADMIN). So maybe
there a some Security-related modern Linux-configurations required for
sftp, which I've not been able to find.
Attached please find terminal dbg-messages in the error-case
(host1=sftp-client,host2=server)
and the ok-case
(host2=sftp-client,host1=server)
