* CIFS: remove bad_network_name flagGermano Percossi2017-07-041-1/+0
| | | | | | | | | | | | | | | | | | | | | | commit a0918f1ce6a43ac980b42b300ec443c154970979 upstream. STATUS_BAD_NETWORK_NAME can be received during node failover, causing the flag to be set and making the reconnect thread always unsuccessful, thereafter. Once the only place where it is set is removed, the remaining bits are rendered moot. Removing it does not prevent "mount" from failing when a non existent share is passed. What happens when the share really ceases to exist while the share is mounted is undefined now as much as it was before.

* CIFS: Fix a possible memory corruption during reconnectPavel Shilovsky2017-07-041-0/+3
| | | | | | | | | | | | | | | commit 53e0e11efe9289535b060a51d4cf37c25e0d0f2b upstream. We can not unlock/lock cifs_tcp_ses_lock while walking through ses and tcon lists because it can corrupt list iterator pointers and a tcon structure can be released if we don't hold an extra reference. Fix it by moving a reconnect process to a separate delayed work and acquiring a reference to every tcon that needs to be reconnected. Also do not send an echo request on newly established connections.
