* scsi: bnx2fc: Fix Kconfig warning & CNIC build errorsRandy Dunlap2021-02-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CNIC depends on MMU, but since 'select' does not follow any dependency chains, SCSI_BNX2X_FCOE also needs to depend on MMU, so that erroneous configs are not generated, which cause build errors in cnic.

Plus number of minor changes, spelling fixes and other trivia. The big merge conflict this time around is the SPDX licence tags. Following discussion on linux-next, we believe our version to be more accurate than the one in the tree, so the resolution is to take our version for all the SPDX conflicts" Note on the SPDX license tag conversion conflicts: the SCSI tree had done its own SPDX conversion, which in some cases conflicted with the treewide ones done by Thomas & co. In almost all cases, the conflicts were purely syntactic: the SCSI tree used the old-style SPDX tags ("GPL-2.0" and "GPL-2.0+") while the treewide conversion had used the new-style ones ("GPL-2.0-only" and "GPL-2.0-or-later"). In these cases I picked the new-style one. In a few cases, the SPDX conversion was actually different, though. As explained by James above, and in more detail in a pre-pull-request thread: "The other problem is actually substantive: In the libsas code Luben Tuikov originally specified gpl 2.0 only by dint of stating: * This file is licensed under GPLv2. In all the libsas files, but then muddied the water by quoting GPLv2 verbatim (which includes the or later than language). So for these files Christoph did the conversion to v2 only SPDX tags and Thomas converted to v2 or later tags" So in those cases, where the spdx tag substantially mattered, I took the SCSI tree conversion of it, but then also took the opportunity to turn the old-style "GPL-2.0" into a new-style "GPL-2.0-only" tag. Similarly, when there were whitespace differences or other differences to the comments around the copyright notices, I took the version from the SCSI tree as being the more specific conversion. Finally, in the spdx conversions that had no conflicts (because the treewide ones hadn't been done for those files), I just took the SCSI tree version as-is, even if it was old-style. The old-style conversions are perfectly valid, even if the "-only" and "-or-later" versions are perhaps more descriptive. * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (185 commits) scsi: qla2xxx: move IO flush to the front of NVME rport unregistration scsi: qla2xxx: Fix NVME cmd and LS cmd timeout race condition scsi: qla2xxx: on session delete, return nvme cmd scsi: qla2xxx: Fix kernel crash after disconnecting NVMe devices scsi: megaraid_sas: Update driver version to 07.710.06.00-rc1 scsi: megaraid_sas: Introduce various Aero performance modes scsi: megaraid_sas: Use high IOPS queues based on IO workload scsi: megaraid_sas: Set affinity for high IOPS reply queues scsi: megaraid_sas: Enable coalescing for high IOPS queues scsi: megaraid_sas: Add support for High IOPS queues scsi: megaraid_sas: Add support for MPI toolbox commands scsi: megaraid_sas: Offload Aero RAID5/6 division calculations to driver scsi: megaraid_sas: RAID1 PCI bandwidth limit algorithm is applicable for only Ventura scsi: megaraid_sas: megaraid_sas: Add check for count returned by HOST_DEVICE_LIST DCMD scsi: megaraid_sas: Handle sequence JBOD map failure at driver level scsi: megaraid_sas: Don't send FPIO to RL Bypass queue scsi: megaraid_sas: In probe context, retry IOC INIT once if firmware is in fault scsi: megaraid_sas: Release Mutex lock before OCR in case of DCMD timeout scsi: megaraid_sas: Call disable_irq from process IRQ poll scsi: megaraid_sas: Remove few debug counters from IO path ...

In previous testing, the type of cleanup notification we'd get from the CQE did not trigger the code that returned the SCSI command. To overcome the previous behavior we would put a reference in bnx2fc_abts_cleanup() to account for the SCSI command. However, in cases where the SCSI command is actually off, we end up with an extra put. The fix for this is to only take the extra put in bnx2fc_abts_cleanup if the completion for the cleanup times out.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For bnx2fc, the source FCoE MAC is stored in the fcoe_port struct in the data_src_mac field. Currently this is set in fcoe_ctlr_recv_flogi which ends up setting it by simply using fc_fcoe_set_mac() which only uses the default FCF-MAC. We still want to store the source FCoE MAC in port->data_src_mac but we want to snoop the FLOGI response payload so as to set it in the following method: 1. If a granted_mac is found, use that. 2. If not granted_mac is there but there is a FCF-MAP from the FCF then create the MAC from the FCF-MAP and the destination ID from the frame. 3. If there is no FCF-MAP the use the spec. default FCF-MAP and the destination ID from the frame.

* | drivers: Remove explicit invocations of mmiowb()Will Deacon2019-04-081-2/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | mmiowb() is now implied by spin_unlock() on architectures that require it, so there is no reason to call it from driver code. This patch was generated using coccinelle: @mmiowb@ @@ - mmiowb(); and invoked as: $ for d in drivers include/linux/qed sound; do \ spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation. If you've ended up bisecting to this commit, you can reintroduce the mmiowb() calls using wmb() instead, which should restore the old behaviour on all architectures other than some esoteric ia64 systems.

Additionally Christoph refactored gdth as part of the dma changes. The major mid-layer change this time is the removal of bidi commands and with them the whole of the osd/exofs driver and filesystem. This is a major simplification for block and mq in particular" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (240 commits) scsi: cxgb4i: validate tcp sequence number only if chip version <= T5 scsi: cxgb4i: get pf number from lldi->pf scsi: core: replace GFP_ATOMIC with GFP_KERNEL in scsi_scan.c scsi: mpt3sas: Add missing breaks in switch statements scsi: aacraid: Fix missing break in switch statement scsi: kill command serial number scsi: csiostor: drop serial_number usage scsi: mvumi: use request tag instead of serial_number scsi: dpt_i2o: remove serial number usage scsi: st: osst: Remove negative constant left-shifts scsi: ufs-bsg: Allow reading descriptors scsi: ufs: Allow reading descriptor via raw upiu scsi: ufs-bsg: Change the calling convention for write descriptor scsi: ufs: Remove unused device quirks Revert "scsi: ufs: disable vccq if it's not needed by UFS device" scsi: megaraid_sas: Remove a bunch of set but not used variables scsi: clean obsolete return values of eh_timed_out scsi: sd: Optimal I/O size should be a multiple of physical block size scsi: MAINTAINERS: SCSI initiator and target tweaks scsi: fcoe: make use of fip_mode enum complete ...

That change was incomplete and gcc quietly converted in various places between the fip_mode and the fip_state enum values with implicit enum conversions, which fortunately cannot cause any issues in the actual code's execution. clang however warns about these implicit enum conversions in the scsi drivers. This commit consolidates the use of the two enums, guided by clang's enum-conversion warnings. This commit now completes the use of the fip_mode: It expects and uses fip_mode in {bnx2fc,fcoe}_interface_create and fcoe_ctlr_init, and it calls fcoe_ctrl_set_set() with the correct values in fcoe_ctlr_link_up(). It also breaks the association between FIP_MODE_AUTO and FIP_ST_AUTO to indicate these two enums are distinct.
