Description william rose 2002-06-12 18:34:57 EDT
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 

Description of problem:
I just upgraded 6-8-2002 to kernel 2.4.9-31 to resolve the security issues with 
tux. As of this morning, when a link targets a PDF file on the web server, tux 
fails to deliver it correctly, possibly not at all. To test this, I shut down 
tux and started Apache up and all links were then available. When tux _is_ 
running, you can right click on the link and save the file to your disk. From 
there it can be opened with a PDF reader. This leads me to believe that the 
Acrobat reader ActiveX component on windows, and the plugin on the Linux 
version, are using a corrupt content-size header to determine how much data to 
request over the wire. It is a known fact that browsers generally ignore the 
content-size header, thus right clicking and saving the file is successful 
through the browser. It is by these facts that I believe the content-size 
header is corrupt when tux sends it. This is occuring intermittenly.

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

How reproducible:

Steps to Reproduce:
1. Run tux (seemed to be running for a few days before showing up).
2. Open browser.
3. Click on a PDF link.

Software from RedHat 7.2 install running:

Kernel 2.4.9-31 tux and required proc utils

I think this is a kernel side, not a tux daemon side, issue.
Comment 3 Ingo Molnar 2003-07-05 04:05:48 EDT
Please re-check with the current Tux kernel - still problematic?
