Subject: [PATCH] drbdadm,v9: do not segfault when re-configuring proxy with no
|
|
path
|
|
|
|
This prevents a segfault when a resource has a connection with no path,
|
|
and "adjust" attempts to re-configure proxy.
|
|
|
|
This could occur as follows, when drbd-proxy-ctl is not on $PATH:
|
|
* Bring resource and connection up without proxy.
|
|
* Add proxy configuration to res file.
|
|
* "drbdadm adjust <res>" - this causes the existing path to be deleted,
|
|
but no new path is created because drbd-proxy-ctl cannot be executed.
|
|
* "drbdadm adjust <res>" - segfault.
