* scsi_error: fix invalid setting of host byteUlrich Obergfell2014-06-24
| | | | | | | | | | | | | | | | | | | After scsi_try_to_abort_cmd returns, the eh_abort_handler may have already found that the command has completed in the device, causing the host_byte to be nonzero (e.g. it could be DID_ABORT). When this happens, ORing DID_TIME_OUT into the host byte will corrupt the result field and initiate an unwanted command retry. Fix this by using set_host_byte instead, following the model of commit 2082ebc45af9c9c648383b8cde0dc1948eadbf31.

Current firmware filters out these events already, but some out of date firmware doesn't, so the driver needs to filter them out too.

This includes the conversion of qlt_handle_cmd_for_atio() to perform qla_tgt_sess lookup before dispatching a command descriptor into qla_tgt_wq process context, along with handling the case where no active session exists, and subsequently kicking off a seperate process context for qlt_create_sess_from_atio() to create a new one. It also includes moving tag allocation into generic code within qlt_get_tag(), so that the same logic can be shared between qlt_handle_cmd_for_atio() + qlt_create_sess_from_atio() contexts. Also, __qlt_do_work() has been made generic between both normal process context in qlt_do_work() + qlt_create_sess_from_atio(). Next, update qlt_free_cmd() to release the percpu-ida tags, and drop the now-unused global qla_tgt_cmd_cachep. Finally in tcm_qla2xxx code, tcm_qla2xxx_check_initiator_node_acl() has been updated to use transport_init_session_tags() along with a hardcoded TCM_QLA2XXX_DEFAULT_TAGS=2088 as the number of qla_tgt_cmd descriptors to pre-allocate per qla_tgt_sess instance.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Define separate fields in the sock structure for configuring disabling checksums in both TX and RX-- sk_no_check_tx and sk_no_check_rx. The SO_NO_CHECK socket option only affects sk_no_check_tx. Also, removed UDP_CSUM_* defines since they are no longer necessary.
