From 8b1d03434ee44b08c57f50403eaeab099facebf5 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Thu, 31 Jan 2008 13:36:53 -0600 Subject: [SCSI] libiscsi: fix session age rollover and remove cid encoding The session age mask is only 4 bits, but session->age is 32. When it gets larger then 15 and we try to or the bits some bits get dropped and the check for session age in iscsi_verify_itt is useless. The ISCSI_CID_MASK related bits are also useless since cid is always one.
