Subject: [PATCH] libmultipath: orphan paths if coalesce_paths frees newmp
|
|
|
|
If coalesce_paths() is called without a mpvec, it will free all the
|
|
multipath devices on newmp at the end. This will clear pp->mpp from the
|
|
path, but it doesn't completely unitialize them. cli_add_map() can call
|
|
coalsce_paths() this way, when adding a device that doesn't currently
|
|
exist. cli_add_map() first creates the device in the kernel, and then
|
|
calls ev_add_map() to add it to multipathd. If something goes wrong in
|
|
ev_add_map(), the paths will still be initialized, even though they're
|
|
orphans.
|
|
|
|
Fix this by calling remove_map() to orphan the paths that belong to
|
|
the multipath devices being deleted by coalesce_paths().
