Enable TCMU to handle bidirectional SCSI commands. In such cases, entries in iov[] cover both the Data-In and the Data-Out buffers. The first iov_cnt entries correspond to the Data-Out buffer, while the remaining iov_bidi_cnt entries correspond to the Data-In buffer. Signed-off-by:

Introduce alloc_and_scatter_data_area()/gather_and_free_data_area() functions that allocate/deallocate space from the data area and copy data to/from a given scatter-gather list. These functions are needed so the next patch, introducing support for bidirectional commands in TCMU, can use the same code path both for t_data_sg and for t_bidi_data_sg. Signed-off-by:

Fields t_bidi_data_sg and t_bidi_data_nents are set only in the presence of BIDI commands. This means that the underlying code (for example TCMU) cannot inspect them when the SCSI command is not a BIDI one. Ensure the code always initializes these fields with the given values, even when the SCSI command is not a BIDI one. Set t_bidi_data_sg to sgl_bidi (which should be NULL for non-BIDI commands) and t_bidi_data_nents to sgl_bidi_count (which should be 0 for non-BIDI commands). This allows the underlying code to use these fields unconditionally. Signed-off-by:

Field shost->max_cmd_len is used to inform Linux / the SCSI midlayer of the maximum CDB size an LLD is capable of handling. Set this field to SCSI_MAX_VARLEN_CDB_SIZE for target, to enable support for variable-sized CDBs (0x7E). Also remove the definition of TL_SCSI_MAX_CMD_LEN since it is now redundant. Signed-off-by:

Drivers may override the WCE flag, in which case the DPOFUA flag in MODE SENSE might differ from the check used to reject invalid FUA bits in sbc_check_dpofua. Also now that we reject invalid FUA bits early there is no need to duplicate the same buggy check down in the fileio code. As the DPOFUA flag controls th support for FUA bits on read and write commands as well as DPO key off all the checks off a single helper, and deprecate the emulate_dpo and emulate_fua_read attributs. This fixes various failures in the libiscsi testsuite. Personally I'd prefer to also remove the emulate_fua_write attribute as there is no good reason to disable it, but I'll leave that for a separate discussion. Signed-off-by:

Support for markers is currently broken because of a bug in iscsi_enforce_integrity_rules(): the "IFMarkInt_Reject" and "OFMarkInt_Reject" variables are always equal to 1 in iscsi_enforce_integrity_rules(). Moreover, fixed interval markers keys (IFMarker, OFMarker, IFMarkInt and OFMarkInt) are obsolete according to iSCSI RFC 7143: >From http://tools.ietf.org/html/rfc7143#section-13.25: 13.25. Obsoleted Keys This document obsoletes the following keys defined in [RFC3720]: IFMarker, OFMarker, OFMarkInt, and IFMarkInt. However, iSCSI implementations compliant to this document may still receive these obsoleted keys -- i.e., in a responder role -- in a text negotiation. When an IFMarker or OFMarker key is received, a compliant iSCSI implementation SHOULD respond with the constant "Reject" value. The implementation MAY alternatively respond with a "No" value. However, the implementation MUST NOT respond with a "NotUnderstood" value for either of these keys. When an IFMarkInt or OFMarkInt key is received, a compliant iSCSI implementation MUST respond with the constant "Reject" value. The implementation MUST NOT respond with a "NotUnderstood" value for either of these keys. This patch disables markers by turning the corresponding parameters to read-only. The default value of IFMarker and OFMarker remains "No" but the user cannot change it to "Yes" anymore. The new value of IFMarkInt and OFMarkInt is "Reject".

The reason this bounce buffer exists is to allow code reuse between rd_mcp and fileio in DIF mode. But the fact is, that this bounce is really not needed at all, we can simply call sbc_dif_verify on cmd->t_prot_sg and use it for file IO. This also removes fd_do_prot_rw as fd_do_rw was generalised to receive file pointer, block size (8 bytes for DIF data) and total data length.

Instead of providing DIF verify routines for read/write that are almost identical and conditionally copy protection information, just let the caller do the right thing. Have a single sbc_dif_verify that handles an sgl (that does NOT copy any data) and a protection information copy routine used by rd_mcp and fileio backend. In the WRITE case, call sbc_dif_verify with cmd->t_prot_sg and then do the copy from it to local sgl (assuming the verify succeeded of course). In the READ case, call sbc_dif_verify with the local sgl and if it succeeds, copy it to t_prot_sg (or not if we are stripping it). (Fix apply breakage from commit c8367778 - nab) Tested-by:

There is just one configfs subsystem in the target code, so we might as well add two helpers to reference / unreference it from the core code instead of passing pointers to it around. This fixes a regression introduced for v4.1-rc1 with commit 9ac8928e, where configfs_depend_item() callers using se_tpg_tfo->tf_subsys would fail, because the assignment from the original target_core_subsystem[] is no longer happening at target_register_template() time.

Once upon a time, iscsit_get_tpg() was using an un-interruptible lock. The signal_pending() usage was a check to allow userspace to break out of the operation with SIGINT. AFAICT, there's no reason why this is necessary anymore, and as reported by Alexey can be potentially dangerous. Also, go ahead and drop the other two problematic cases within iscsit_access_np() and sbc_compare_and_write() as well. Found by Linux Driver Verification project (linuxtesting.org). Reported-by:

TCMU requires more work to correctly handle both user handlers that want all SCSI commands (pass_level=0) for a se_device, and also handlers that just want I/O commands and let the others be emulated by the kernel (pass_level=1). Only support the latter for now. For full passthrough, we will need to support a second se_subsystem_api template, due to configfs attributes being different between the two modes. Thus pass_level is extraneous, and we can remove it. The ABI break for TCMU v2 is already applied for this release, so it's best to do this now to avoid another ABI break in the future.

AMD CPUs don't reinitialize the SS descriptor on SYSRET, so SYSRET with SS == 0 results in an invalid usermode state in which SS is apparently equal to __USER_DS but causes #SS if used. Work around the issue by setting SS to __KERNEL_DS __switch_to, thus ensuring that SYSRET never happens with SS set to NULL. This was exposed by a recent vDSO cleanup.

Pull intel iommu updates from David Woodhouse: "This lays a little of the groundwork for upcoming Shared Virtual Memory support — fixing some bogus #defines for capability bits and adding the new ones, and starting to use the new wider page tables where we can, in anticipation of actually filling in the new fields therein. It also allows graphics devices to be assigned to VM guests again. This got broken in 3.17 by disallowing assignment of RMRR-afflicted devices. Like USB, we do understand why there's an RMRR for graphics devices — and unlike USB, it's actually sane. So we can make an exception for graphics devices, just as we do USB controllers. Finally, tone down the warning about the X2APIC_OPT_OUT bit, due to persistent requests. X2APIC_OPT_OUT was added to the spec as a nasty hack to allow broken BIOSes to forbid us from using X2APIC when they do stupid and invasive things and would break if we did. Someone noticed that since Windows doesn't have full IOMMU support for DMA protection, setting the X2APIC_OPT_OUT bit made Windows avoid initialising the IOMMU on the graphics unit altogether. This means that it would be available for use in "driver mode", where the IOMMU registers are made available through a BAR of the graphics device and the graphics driver can do SVM all for itself. So they started setting the X2APIC_OPT_OUT bit on *all* platforms with SVM capabilities. And even the platforms which *might*, if the planets had been aligned correctly, possibly have had SVM capability but which in practice actually don't" * git://git.infradead.org/intel-iommu: iommu/vt-d: support extended root and context entries iommu/vt-d: Add new extended capabilities from v2.3 VT-d specification iommu/vt-d: Allow RMRR on graphics devices too iommu/vt-d: Print x2apic opt out info instead of printing a warning iommu/vt-d: kill bogus ecap_niotlb_iunits()
