Package: openssh-client
Version: 1:10.1p1-1
Severity: normal
After upgrading to 10.1p1-1, interactive sessions are very slow and
halting while producing output from the server, as if the client is
missing some poll()/select() triggers. It's a bit hard to show the
timing in an email, but if I ssh to a local machine that is running
trixie's 10.0p1-7, like this:
$ ssh -o ControlMaster=yes segfault.intra.peff.net
then no output is produced immediately. If I start typing (say, "echo
foo") then output does start appearing, but always behind, as if ssh is
not correctly calling read() until my local typing kicks it into a
polling loop.
If I run the command above under "strace -tt", it sits (with no output)
on this call:
963687 01:34:16.851998 read(6
And if I then type "echo foo", I finally get some output, with strace
showing:
