Subject: [PATCH] issue: 3525812 Fix buffer leak socketextreme
|
|
|
|
|
|
|
|
|
|
In reclaim buffer api - vma_socketxtreme_free_vma_packets
|
|
|
|
|
we use reclaim_recv_buffers method which uses try_lock
|
|
|
|
|
on the ring, but in case the lock has failed - buffers
|
|
|
|
|
will not be returned.
|
|
|
|
|
The fix - in case the ring is locked - reclaim buffers
|
|
|
|
|
to the global pool.
|
