439f68e555 CONNECTION: Track the connection state and callback via the context structure 
Dont free the connection state when login is finished, instead track it via the
iscsi context structure and free it once the context is destroyed

77d8e41be7 TESTS: Add a mechanism to temporarily disable the session reconnect 
Some tests may cause a target to drop the session.
For these tests we DO want the test tool to detect that the command
failed and later reconnect the session again when we proceed to the next subtest

6f4afb6edb MEDIUM_NOT_PRESENT/TRAY-CLOSED/TRAY_OPEN is not an error that blocks a successful connect 2012-07-12 18:55:35 +10:00

801bfb342d Login: dont fail the login just because there is no media in a device 
in that case we will never reach test unit ready being successful since it will fail with NOT_READY/MEDIUM_NOT_PRESENT.
Treat this sense code as a successful login as far as the login process is concerned

343d86dca7 get rid of the _async() scsi functions. 
We dotn need two interfaces that only diuffer in whether they return a pointer or NULL vs an semiidentical interface that returns 0 or <0

All uses of _async() for scsi tasks should be replaced with the equivalent _task() function instead

f4f6ef5033 change dont automatically free the scsi_task once the callback completes. 
Freeing the scsi_task structure is the responsibility of the application
to either do so during the callback, or later.

190ea92810 Rework error messages generated when login fails to not repeat the same 
thing "Failed to login to target" several times as the error cascades
up through the layers of callbacks.
