Description Travis Crawford 2003-06-16 11:15:46 EDT

Description of problem:
Crash when reading CGI generated kickstart files. Might have something to do
with handling of the content-type line.


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


How reproducible:
Always.


Steps to Reproduce:
1. Write a CGI script that outputs a Kickstart file.
2. Pass ks=http://web_server/script.cgi to the kernel.
3. Watch as the installer crashes.


Actual results:
Anaconda crashes.


Expected results:
Automated install.


Additional info:
A text file (created by wget'ting the script works as expected (the install
works.) When the CGI script is the specified kickstart file anaconda crashes.

Comment 4 Jeremy Katz 2003-06-16 12:21:39 EDT

Your web server is created chunked output which our simplistic http client can't
handle.  You need to configure your web server to not return chunked output.

Newer versions handle this better.

Comment 5 Travis Crawford 2003-06-16 15:50:10 EDT

Thanks for the chunking info. Since chunking is a HTTP/1.1 feature, adding a few
lines to httpd.conf fixed the problem.

SetEnv nokeepalive
SetEnv downgrade-1.0
SetEnv force-response-1.0

Perhaps Anaconda could default to making HTTP/1.0 requests? Or are there any
HTTP/1.1 features that make sticking with the new version better?

Comment 6 Jeremy Katz 2003-06-19 17:57:58 EDT

More current releases only request 1.0
