Commit 256963d6b (autofs-5.1.7 - refactor lookup_prune_one_cache() a bit)
|
|
|
beb904 |
changed the position of the getting the next enumeration map entry but
|
|
|
beb904 |
failed to update a couple of other locations that assume the next map
|
|
|
beb904 |
entry has been set. Under certain fairly common conditions this leads
|
|
|
beb904 |
to an infinite loop.
