Subject: IPQoS not honoured

Date: Wed, 30 Nov 2011 13:52:07 +0100

[Message part 1 (text/plain, inline)]

Package: openssh-client
Version: 1:5.8p1-4
Severity: normal

While openssh-client seems to properly switch between the
lowdelay/throughput QoS classes depending on whether the session is
interactive or not, the new IPQoS option seems to have absolutely no
effect:

  % ssh -vvvo 'IPQoS ef' -4 -Snone vera 2>&1 >/dev/null | egrep tos || echo no match
  debug3: packet_set_tos: set IP_TOS 0x10
  ^D
  % ssh -vvvo 'IPQoS ef' -4 -Snone vera true 2>&1 >/dev/null | egrep tos || echo no match
  debug3: packet_set_tos: set IP_TOS 0x08

In both cases, the TOS value should be 0x2e (class ef). Using the
hex number does not work either:

  % ssh -vvvo 'IPQoS 0x2e' -4 -Snone vera 2>&1 >/dev/null | egrep tos || echo no match
  debug3: packet_set_tos: set IP_TOS 0x10
  ^D
  % ssh -vvvo 'IPQoS 0x2e' -4 -Snone vera true 2>&1 >/dev/null | egrep tos || echo no match
  debug3: packet_set_tos: set IP_TOS 0x08

I have also verified the actual packets emitted using tcpdump on the
next hop.

Exactly the same behaviour can be observed with IPv6 after upgrading to
1:5.9p1-7 (see #643312).

Changes: 
 openssh (1:6.0p1-1) unstable; urgency=low
 .
   [ Roger Leigh ]
   * Display dynamic part of MOTD from /run/motd.dynamic, if it exists
     (closes: #669699).
 .
   [ Colin Watson ]
   * Update OpenSSH FAQ to revision 1.113, fixing missing line break (closes:
     #669667).
   * New upstream release (closes: #671010,
     http://www.openssh.org/txt/release-6.0).
     - Fix IPQoS not being set on non-mapped v4-in-v6 addressed connections
       (closes: #643312, #650512, #671075).
     - Add a new privilege separation sandbox implementation for Linux's new
       seccomp sandbox, automatically enabled on platforms that support it.
       (Note: privilege separation sandboxing is still experimental.)
   * Fix a bashism in configure's seccomp_filter check.
   * Add a sandbox fallback mechanism, so that behaviour on Linux depends on
     whether the running system's kernel has seccomp_filter support, not the
     build system's kernel (forwarded upstream as
     https://bugzilla.mindrot.org/show_bug.cgi?id=2011).

With 6.0, I get exactly the same behaviour as before, so #650512 is
not fixed, sorry…

According to https://bugzilla.mindrot.org/show_bug.cgi?id=1963#c6,
the bug is in Debian only, not in upstream…

However, I cannot find anything in debian/patches that would explain
this…

Subject: Appears to be an upstream bug

Date: Fri, 13 Sep 2013 13:55:38 -0400

I just built the latest upstream and see the problem, so I don't think this is Debian
specific. 

I built both openssh-6.0p1 (the version that comes with wheezy) and openssh-6.3p1 (latest
official release).

Here's a post to debian-ssh that describes what I'm doing to see the problem:

IPQoS not affecting TCP_NODELAY
http://lists.debian.org/debian-ssh/2013/09/msg00010.html

I'm also seeing the original problem that was reported:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=650512#5
