In case the sendtargets response payload exceeds the initiator MRDSL, we must
break the response into pieces and prepare for the initiator next (empty) text
messages.
We write the maximum payload the initiator can receive (or less if we have less)
and if we are not done, we set C=1, F=0, TTT!=0xffffffff. In a discovery session
we accept empty text request by assuming they are consecutive sendtargets (does
anyone have a better idea here?).
The set consist of 2 preparation patches, a patch to add this support and another
patch to fix a bug in isert.
Changes from v0:
- Fix typo s/cusecutive/consecutive/g
Sagi Grimberg (4):
iscsi-target: Introduce session_get_next_ttt
iscsi-target: Don't over-allocate sendtargets text resp buffer
iscsi-target: Support multi-sequence sendtargets text response
iser-target: Fix wrong allocation in the case of an empty text
