When libiscsi is built with clang several spurious
missing-field-initializers warnings like the following are reported:
test_async_write.c:61:45: error: missing field 'completed' initializer
[-Werror,-Wmissing-field-initializers]
struct tests_async_write_state state = { 0 };
These appear to be due to clang being overzealous in its checking
because the code is legal C (see
https://llvm.org/bugs/show_bug.cgi?id=21689 ) but it causes compilation
to be aborted. Workaround the problem by specifying a 0 or NULL for each
structure member.
Some iSCSI targets provide a link-local IPv6 address as a portal, but that
is unusable without knowing the interface (aka scope-id) to use for the
connection. This causes iscsi-ls to report an EINVAL and exit. Just
skip the error.

This function allows the caller to determine the number of PDUs queued
for transmission for a given iscsi context.

Currently the iscsi_task_mgmt_abort_task_[a]sync() functions cancel any
queued or dispatched (awaiting response) PDUs prior to transmitting the
ABORT TASK TMF request, which means that a TMF request may be sent which
references a PDU that the target never received.

These values are defined in rfc3720
10.6. Task Management Function Response
-> 10.6.1. Response
The response field is a single byte value, and is already used within
libiscsi as a command_data parameter for iscsi_task_mgmt_async()
callbacks.

if we drop a PDU which has a callback we should invoke it otherwise
the caller may wait infinetely for a command completion.

This seriously breaks qemu NOP timeouts and probably other things.
The reason is that the
define ISCSI_PDU_ERROR_ON_RECONNECT 0x00000016
is masking bits 0x2 and 0x4 as well.
Correctly it should read:
define ISCSI_PDU_ERROR_ON_RECONNECT 0x00000010
However, the better solution for this approach is invoke all callbacks
of PDUs which carry the ISCSI_PDU_DROP_ON_RECONNECT flag. This will
make sure that callbacks of whatever sync tasks are invoked.
This reverts commit 0407cf6aed.
Dispatch a number of Compare And Write requests simultaneously via
separate iSCSI sessions and await all responses.

Dispatch a number of READ10 requests simultaneously, and await all
responses.
The iscsi-support test helper functions are currently all synchronous,
so this test mostly uses the bare libiscsi API. As new async tests are
added, we can make a more informed decision on which boilerplate code
can be split out.
