but immediate data is not sent in the RCaP message.

iscsi_logout_sync in lu_reset_simple will still refer to wtask in the
case that we bail out due to reconnect failure.
abort_simple would sometimes refer to wtask during iscsi_logout_sync,
even if the test passed.

Since it is easy to trigger a stack overflow with variable-length arrays,
use dynamic memory allocation instead of VLAs. Add -Wvla to the compiler
options such that no new VLAs get introduced.

Align iscsi_header[] and data[] on an 8-byte boundary instead of on a 4-byte
boundary. With this patch applied pahole produces the following output:
struct iser_rx_desc {
struct iser_hdr iser_header; /* 0 28 */
char pad1[4]; /* 28 4 */
char iscsi_header[48]; /* 32 48 */
/* --- cacheline 1 boundary (64 bytes) was 16 bytes ago --- */
char data[128]; /* 80 128 */
/* --- cacheline 3 boundary (192 bytes) was 16 bytes ago --- */
struct ibv_sge rx_sg; /* 208 16 */
struct ibv_mr * hdr_mr; /* 224 8 */
char pad2[24]; /* 232 24 */
/* size: 256, cachelines: 4, members: 7 */
};
Additionally, this patch fixes the following build errors:
iser.c: In function 'iser_alloc_rx_descriptors':
iser.c:916:11: error: taking address of packed member of 'struct iser_rx_desc' may result in an unaligned pointer value [-Werror=address-of-packed-member]

The iSCSICHAP.Simple test ensures that CHAP_A comma separated lists
are correctly handled. iSCSICHAP.Invalid tests a range of invalid

For now this only changes iSCSIDataSnInvalid to use
iscsi_pdu_set_datasn() instead of scsi_set_uint32().
iSCSICmdSnTooHigh/Low changes should also be possible, as noted, but
haven't been converted yet.

libiscsipriv.la exposes all symbols, so allows tests to perform low
level PDU manipulation, etc. without duplicating code.
As a trade-off, this results in a larger iscsi-test-cu, with libiscsi.so
linking removed.

callback, so the dlsym based overloading can now be dropped.

rfc3720 indicates that SendTargets on discovery *and* normal operational
sessions must be supported by targets:
A system that contains targets MUST support discovery sessions on
each of its iSCSI IP address-port pairs, and MUST support the
SendTargets command on the discovery session.
...
A target MUST support the SendTargets command on operational

Discovered this while running iSCSI.iSCSITMF AbortTaskSimpleAsync
test case. For Task Management command iser_pdu->iscsi_pdu.scsi_cbdata
is not set. When test case tries to send Task Management command
via common API iser_send_command() - it calls overflow_data_size
which tries to dereference scsi_cbdata leading to SEGFAULT.
Added a non-NULL check for scsi_cbdata before accessing it.
