Description Thomas Haller 2016-09-08 19:40:32 EDT

backport a trivial fix for a crash:

https://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=4a535e6213bb5de05f166c29debc65fc04a7a3b8


for example:

  $ nmcli --complete-args connection add type vpn vpn-type ''
  Segmentation fault (core dumped)



The impact is moderate, but the fix is trivial and riskless.

Comment 1 Thomas Haller 2016-09-09 07:13:34 EDT

For the crash to happen, you need to install at least one VPN plugin that has no "aliases".

Currently, the only VPN plugin with aliases is nm-libreswan. So, install any plugin (except nm-libreswan).


Note, the crash can also happen during interactive edit mode in nmcli, not only during --complete-args. That is just an easy example

Comment 2 Thomas Haller 2016-09-09 09:56:36 EDT

merged to dist-git and will be part of NetworkManager-1.4.0-8.el7. Build still missing.

Comment 4 Vladimir Benes 2016-09-15 06:56:35 EDT

Can list all arguments w/o segfault with various plugins installed.
