1. Commands start going to the init_cmd_list probably because SCST was suspended 2. A command is now waiting in the init_cmd_list, it was not yet completely initialized (more impotently cmd->dev == NULL) 3. A clear task set for the same lun arrives from a different initiator 4. The command is marked as aborted from other initiator and released from the init list. 5. The command gets to the PRE_XMIT_RESPONSE state, since it was aborted the scst_xmit_process_aborted_cmd is called. 6. At this stage since the command is marked as aborted by other initiator the scst checks for the device TAS flag (cmd->dev->tas) however cmd->dev is NULL and we crash on Null pointer de-referencing. git-svn-id: http://svn.code.sf.net/p/scst/svn/trunk@1466 d57e44dd-8a1f-0410-8b47-8ef2f437770f
This is the SCST development repository. It contains not a single project SCST as one can think, but a number of them, which are divided as the following: 1. SCST core in scst/ subdirectory 2. Administration utility for SCST core scstadmin in scstadmin/ 3. Target drivers in own subdirectories qla2x00t/, iscsi-scst/, etc. 4. User space programs in usr/ subdirectory, like fileio_tgt. 5. Some various docs in doc/ subdirectory. Those subprojects are in most cases independent from each other, although some of them depend from the SCST core. They put in the single repository only to simplify their development, they are released independently. Thus, use "make all" only if you really need to build everything. Otherwise build only what you need, like for iSCSI-SCST: make scst scst_install iscsi iscsi_install For more information about each subproject see their README files.
