[Touch-packages] [Bug 1767283] Re: nc doesn't support "-s IP" option

[Launchpad Bug Tracker]

This bug was fixed in the package netcat-openbsd - 1.187-1ubuntu0.1

---
netcat-openbsd (1.187-1ubuntu0.1) bionic; urgency=medium

  * Re-enable usage of '-s' (local source address) and '-p' (local source
port) in client mode (when '-l' is unset).  Regression introduced in
a Debian-specific patch added in 1.187-1. (LP: #1767283).
Backport of https://salsa.debian.org/debian/netcat-openbsd/commit/338b1fa7

Bug description:
  [Impact]

   * This worked in former relases, so from a LTS->LTS upgraders POV it is 
 an upgrade regression
   * The impact is that local source (-s) can no more be used as before
   * The fix is backporting the fix that we made in Debian (but without all 
 the noise of the arg parsing rewrite for SRU simplicity)

  [Test Case]

   * Run with local source port, like your local SSH for example:
   $ netcat -s 127.0.0.1 127.0.0.1 22 < /dev/null

  [Regression Potential]

   * the Minimized change (compared to the big change that versions going 
 forward got) should be safe as it just allows a case that was formerly 
 forbidden in arg-parsing. Never the less there could be a regression if 
 one of those combinations causes an issue when ran where it formerly 
 just was denied on arg parse. Think a script that since Bionic fails 
 (due to this bug) but once enabled will "work" and DUE TO THAT might 
 then trigger actions that are an issue.
 Never the less, since currently in Bionic this just fails, I'd assume 
 the this is a rather theoretical risk - and being a regression to 
 former releases we should fix it to make LTS->LTS upgraders suffer 
 less.

  Hey,

  netcat shows a usage error if i try to use the "-s" option:

  Example in Bionic:

  $ netcat -s 127.0.0.1 127.0.0.1 22 < /dev/null
  usage: nc [-46CDdFhklNnrStUuvZz] [-I length] [-i interval] [-M ttl]
     [-m minttl] [-O length] [-P proxy_username] [-p source_port]
     [-q seconds] [-s source] [-T keyword] [-V rtable] [-W recvlimit] [-w 
timeout]
     [-X proxy_protocol] [-x proxy_address[:port]][destination] [port]

  Example in Xenial:

  netcat -s 127.0.0.1 127.0.0.1 22 < /dev/null
  SSH-2.0-OpenSSH_7.2p2 Ubuntu-4ubuntu2.4

  Manpage shows that the option is still availible and should work. Both
  systems use openbsd netcat.

i can confirm that 1.187-1ubuntu0.1 fixes the issue. I did a quick

[Touch-packages] [Bug 1767283] Re: nc doesn't support "-s IP" option

[Łukasz Zemczak]

Hello Stefan, or anyone else affected,

Accepted netcat-openbsd into bionic-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/netcat-
openbsd/1.187-1ubuntu0.1 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-bionic to verification-done-bionic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-bionic. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

Found a much better backport much more suited for the SRU process.
New build in ppa, if it tests fine I'll propose that instead.

  Hey,

  netcat shows a usage error if i try to use the "-s" option:

  Example in Xenial:

  netcat -s 127.0.0.1 127.0.0.1 22 < /dev/null

[Touch-packages] [Bug 1767283] Re: nc doesn't support "-s IP" option

[ Christian Ehrhardt ]

I backported the changes which had a lot of extra noise that had to be dropped.
Now a build is ready in ppa [1]

I haven't actually read the patch too much yet but found the build to not solve 
the issues for me on the example from the man page - so I started taking a 
deeper look.
It really works with the newer upstream version, so the patch needs a backport 
plus soem adaption to work in Bionic.

I found a snippet that I missed on the backport (ugly :-/) a better
version built now and works for me. Due to the complexity thou and my
unfamiliarity with the code I'd ask for some extra testing thou.

I'm proposing an SRU-MP but really any extra check is welcome.

netcat-openbsd (1.190-2) unstable; urgency=low

  * d/patches/misc-failures-and-features.patch: Refactor option/argument
verification logic and re-enable usage of '-s' (local source address) and
'-p' (local source port) in client mode (when '-l' is unset).  Regression
introduced in version 1.187-1 of that file.  Closes: #897020, LP: #1767283.
  * debian/control: Bump Standards-Version to 4.1.4 (no changes necessary).

[Touch-packages] [Bug 1767283] Re: nc doesn't support "-s IP" option

[ChristianEhrhardt]

1.190-2 is in cosmic-proposed, but right now some tests still fail for 
18.10/Cosmic not being fully open (e.g. no autotest/cloud images or missing 
18.10 in postgres common.
So I have to beg your pardon to wait a bit more :-/

Fix is now available in [1].
But needs to be picked up for 18.10 (once archive is open in a few days) and 
then prepped as 18.04 SRU.

[Touch-packages] [Bug 1767283] Re: nc doesn't support "-s IP" option

[ChristianEhrhardt]

I'm not an expert on netcat but I hope this initial triage helps the
next that will look at it.

I reported to Debian as well as they are also affected.
Especially since the change came from Guilhem - it might be best to think about 
a solution together.

[Touch-packages] [Bug 1767283] Re: nc doesn't support "-s IP" option

[ChristianEhrhardt]

In gdb I see it gets to read -s

case 's':
sflag = optarg;
break;

It realizes no more options are there and then ends at
} else if (argv[0] && argv[1]) {
host = argv[0];
uport = [1];
if (pflag || sflag)
usage(1);

And sflag is set, so it reports usage and exits.
The particular check in this path of pflag/sflag didn't exist back then.

I found this comes in via a patch
  debian/patches/misc-failures-and-features.patch
That was in Debian and Ubuntu since late 2016

This patch was modified by:
commit 2ebffb014c830e49f6fad600c59cc1b82fe356a4
Author: Guilhem Moulin 
Date:   Sun Dec 3 22:58:11 2017 +0100

Allow usage of -s with -l for consistency with netcat-traditional.

Since then this is also in Debian.

Title:
  nc doesn't support "-s IP" option

Status in netcat-openbsd package in Ubuntu:
  Confirmed

Bug description:
  Hey,

  netcat shows a usage error if i try to use the "-s" option:

  Example in Bionic:

  $ netcat -s 127.0.0.1 127.0.0.1 22 < /dev/null
  usage: nc [-46CDdFhklNnrStUuvZz] [-I length] [-i interval] [-M ttl]
     [-m minttl] [-O length] [-P proxy_username] [-p source_port]
     [-q seconds] [-s source] [-T keyword] [-V rtable] [-W recvlimit] [-w 
timeout]
     [-X proxy_protocol] [-x proxy_address[:port]][destination] [port]

  Example in Xenial:

  netcat -s 127.0.0.1 127.0.0.1 22 < /dev/null
  SSH-2.0-OpenSSH_7.2p2 Ubuntu-4ubuntu2.4

  Manpage shows that the option is still availible and should work. Both
  systems use openbsd netcat.

  $ type netcat
  netcat is hashed (/bin/netcat)
  $ ls -lah /bin/netcat
  lrwxrwxrwx 1 root root 24 Apr 25 21:56 /bin/netcat -> /etc/alternatives/netcat
  $ ls -lah /etc/alternatives/netcat
  lrwxrwxrwx 1 root root 15 Apr 25 21:56 /etc/alternatives/netcat -> 
/bin/nc.openbsd
