Description Grant Gainey 2017-02-16 20:24:01 UTC

+++ This bug was initially created as a clone of Bug #1423003 +++

Description of problem:

The yum-rhn-plugin sends http-headers that are separated by only a newline, when the spec requires CRLF.

In the presence of an httpd which enforces the spec, this results in any attempt to update/install content returning

error was [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 400 Bad Request"

Version-Release number of selected component (if applicable):

The bug was introduced in yum-rhn-plugin-0.8.4-1. The problem was harmless until uncovered by fixes for httpd that tightened whitespace processing.

How reproducible:

See https://bugzilla.redhat.com/show_bug.cgi?id=1422518 for gory details. The net is, 'yum update a system that is talking to a satellite-5 whose httpd is at 2.2.15-60 or higher'.

Actual results:

error was [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 400 Bad Request"

Expected results:

successful install/update of packages.

Additional info:

This BZ is for getting the client-side fix in place for RHEL5, BZ#1422518 is for getting a workaround in place on the Satellite5 backend.

We need to fix this in active z-streams as well

Comment 1 Grant Gainey 2017-02-16 20:25:09 UTC

As for RHEL6, this needs to get into active zstreams as well

Comment 2 Grant Gainey 2017-02-16 20:37:43 UTC

Proposed solution:

Comment 3 Ales Dujicek 2017-02-17 14:13:02 UTC

RHEL5 is not affected by this issue, yum-rhn-plugin does not include that part of code

# rpm -q yum-rhn-plugin
yum-rhn-plugin-0.5.4.1-7.el5

# grep curl /usr/lib/yum-plugins/rhnplugin.py || echo no-curl
no-curl

I registered RHEL 5 to Satellite 5.8 Beta and it succesfully downloaded repodata of spacewalk-tools (rhel-x86_64-server-5 was empty)

# yum repolist
