Description Goffredo Baroncelli 2014-09-07 12:27:18 UTC 
Description of problem:
The MODULE_CONF directive is ignored at installing time

Version-Release number of selected component (if applicable):
v2.2.0.3

How reproduce:
Add a MODULE_CONF directive in the dkms.conf file, and you see that
no file is udated under /etc/modprobe.d/<packagename>.conf

Steps to Reproduce:
1) create an empty file /etc/modprobe.d/dkms.conf
2) create a test package
3) Add a MODULE_CONF directive in the test package dkms.conf file
4) install the test package

Actual results:
The directive is not inserted in the /etc/modprobe.d/dkms.conf

Expected results:
The directive should be inserted in the /etc/modprobe.d/dkms.conf

Additional info:

The root of the problem should be in the commit 13d61e8e744 - "Update bash syntax patch" [1],
which changed a line in the function moduleconfig_update_obsoletes()
as following

[...]
   - [[ ${modules_conf_obsoletes[@]} ]] || return 0
  -+ [[ "${modules_conf_obsoletes[*]}" ]] || return 0
  ++ IFS=; [[ "${modules_conf_obsoletes[*]}" ]] || return 0
[...]

Unfortunately if the test fails, the IFS variable is set to ''.
This leads the rest of the code runs wrongly.

A solution I suggest to protect the code by '( )':


   - [[ ${modules_conf_obsoletes[@]} ]] || return 0
  -+ IFS=; [[ "${modules_conf_obsoletes[*]}" ]] || return 0
  ++ ( IFS=; [[ "${modules_conf_obsoletes[*]}" ]] ) || return 0

The severity is high because this change may break existing installation

Comment 1 Simone Caronni 2014-09-08 11:05:47 UTC 
Thanks very much for spotting and providing the fix. DKMS is unmaintained upstream.

Are you a packager already? Would you like to become comaintainer for DKMS in Fedora/EPEL?
