Description Jeremy Allison 2014-04-11 22:19:03 UTC 
Current code doesn't prevent RECVFILE partial reads from being done
against IPC$ and PRINT$ shares. These shares do not use the normal file write backend so data will be left incorrectly in the TCP buffer against open handles.

Back-port of Metze's master patch to follow.

Jeremy.
