This patch fixes a v4.2+ regression introduced by commit c04a6091 that removed support for obsolete sync-and-steering markers usage as originally defined in RFC-3720. The regression would involve attempting to send OFMarker=No + IFMarker=No keys during opertional negotiation login phase, including when initiators did not actually propose these keys. The result for MSFT iSCSI initiators would be random junk in TCP stream after the last successful login request was been sent signaling the move to full feature phase (FFP) operation. To address this bug, go ahead and avoid negotiating these keys by default unless the initiator explicitly proposes them, but still respond to them with 'No' if they are proposed.

This patch fixes a v4.2+ regression introduced by commit 79dc9c9e where lookup of t10_pr_registration->pr_reg_deve and associated ->pr_kref get was missing from __core_scsi3_do_alloc_registration(), which is responsible for setting DEF_PR_REG_ACTIVE. This would result in REGISTER operations completing successfully, but subsequent core_scsi3_pr_seq_non_holder() checking would fail with !DEF_PR_REG_ACTIVE -> RESERVATION CONFLICT status. Update __core_scsi3_add_registration() to drop ->pr_kref reference after registration and any optional ALL_TG_PT=1 processing has completed. Update core_scsi3_decode_spec_i_port() to release the new parent local_pr_reg->pr_kref as well. Also, update __core_scsi3_check_aptpl_registration() to perform the same target_nacl_find_deve() lookup + ->pr_kref get, now that __core_scsi3_add_registration() expects to drop the reference. Finally, since there are cases when se_dev_entry->se_lun_acl can still be dereferenced in core_scsi3_lunacl_undepend_item() while holding ->pr_kref, go ahead and move explicit rcu_assign_pointer() NULL assignments within core_disable_device_list_for_node() until after orig->pr_comp finishes.

This patch is a >= v4.1 regression bug-fix where control CDB emulation logic in commit 38b57f82 now expects a se_cmd->se_sess pointer to exist when determining T10-PI support is to be exposed for initiator host ports. To address this bug, go ahead and add locally generated se_cmd descriptors for copy-offload block-copy to it's own stand-alone se_session nexus, while the parent EXTENDED_COPY se_cmd descriptor remains associated with it's originating se_cmd->se_sess nexus. Note a valid se_cmd->se_sess is also required for future support of WRITE_INSERT and READ_STRIP software emulation when submitting backend I/O to se_device that exposes T10-PI suport.

This patch adds an optional fabric driver provided SGL limit that target-core will honor as it's own internal I/O maximum transfer length limit, as exposed by EVPD=0xb0 block limits parameters. This is required for handling cases when host I/O transfer length exceeds the requested EVPD block limits maximum transfer length. The initial user of this logic is qla2xxx, so that we can avoid having to reject I/Os from some legacy FC hosts where EVPD=0xb0 parameters are not honored. When se_cmd payload length exceeds the provided limit in target_check_max_data_sg_nents() code, se_cmd->data_length + se_cmd->prot_length are reset with se_cmd->residual_count plus underflow bit for outgoing TFO response callbacks. It also checks for existing CDB level underflow + overflow and recalculates final residual_count as necessary. Note this patch currently assumes 1:1 mapping of PAGE_SIZE per struct scatterlist entry.

Very similar to how it went with local_sockaddr. It was embedded in iscsi_login_stats so some changes there, and we needed to copy in a sockaddr_storage comparison function.

This is a more natural format that lets us format it with the appropriate printk specifier as needed. This also lets us handle v4-mapped ipv6 addresses a little more nicely, by storing the addr as an actual v4 sockaddr in conn->local_sockaddr.

The ALLOCATION LENGTH field specifies bytes unless a different requirement is stated in the command definition. An allocation length of zero specifies that no data shall be transferred. This condition shall not be considered an error. So we should just truncate our response rather than return an error.

In a performance profile, taking a mutex in iscsit_increment_maxcmdsn() shows up very high. However taking a mutex around "sess->max_cmd_sn += 1" seems pretty silly: we're not serializing against other contexts in any useful way. I did a quick audit and there don't appear to be any other places that use max_cmd_sn within the mutex more than once, so this lock can't be providing any useful serialization.

Currently we have two different ways to signal an I/O error on a BIO: (1) by clearing the BIO_UPTODATE flag (2) by returning a Linux errno value to the bi_end_io callback The first one has the drawback of only communicating a single possible error (-EIO), and the second one has the drawback of not beeing persistent when bios are queued up, and are not passed along from child to parent bio in the ever more popular chaining scenario. Having both mechanisms available has the additional drawback of utterly confusing driver authors and introducing bugs where various I/O submitters only deal with one of them, and the others have to add boilerplate code to deal with both kinds of error returns. So add a new bi_error field to store an errno value directly in struct bio and remove the existing mechanisms to clean all this up.
