2022-02-27scsi: libfc: Replace one-element arrays with flexible-array membersGustavo A. R. Silva1-2/+2
Use flexible-array members in struct fc_fdmi_attr_entry and fs_fdmi_attrs instead of one-element arrays, and refactor the code accordingly. Also, this helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy(). https://github.com/KSPP/linux/issues/79 https://github.com/ClangBuiltLinux/linux/issues/1590 Link: https://lore.kernel.org/r/20220214223903.GA859464@embeddedor Signed-off-by: Gustavo A.

2021-06-10scsi: fc: FDMI enhancementJaved Hasan1-7/+48
Added RHBA and RPA attributes type and length. As per FC_GC_7 document section "Table 400 – Attribute Entry Types and associated Values" ASCII type attributes length can be vary from "4 to 256 byte". If we keep all RHBA ASCII attributes length 256 then total length is going upto 2750, which is far more than 2048 (max frame size). In libfc we do have logic to split FCP commands but not for CT commands. Practically all version/names get covered with in 64 bytes except OS name, for that we need 128 bytes. Hence length of all RBHA ASCII attributes is reduced to 64 bytes and 128 bytes in case of OS name. RPA attributes total length is within frame size.

2020-07-15scsi: scsi_transport_fc: Match HBA Attribute Length with HBAAPI V2.0 definitionsLee Jones1-2/+2
According to 'include/scsi/scsi_transport_fc.h': "Attributes are based on HBAAPI V2.0 definitions" ... so it seems sane to match the 'HBA Attribute Length' to them.

2019-07-11Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsiLinus Torvalds2-14/+3
Pull SCSI updates from James Bottomley: "This is mostly update of the usual drivers: qla2xxx, hpsa, lpfc, ufs, mpt3sas, ibmvscsi, megaraid_sas, bnx2fc and hisi_sas as well as the removal of the osst driver (I heard from Willem privately that he would like the driver removed because all his test hardware has failed). 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 ...

2017-05-11uapi: export all headers under uapi directoriesNicolas Dichtel1-0/+0
Regularly, when a new header is created in include/uapi/, the developer forgets to add it in the corresponding Kbuild file. This error is usually detected after the release is out.

2012-10-07[SCSI] libfc: fix lun reset failure bugs in fc_fcp_resp handling of FCP_RSP_INFOYi Zou1-0/+6
In LUN RESET testing involving NetApp targets, it is observed that LUN RESET is failing. The fc_fcp_resp() is not completing the completion for the LUN RESET task since fc_fcp_resp assumes that the FCP_RSP_INFO is 8 bytes with the 4 byte reserved field, where in case of NetApp targets the FCP_RSP to LUN RESET only has 4 bytes of FCP_RSP_INFO. This leads fc_fcp_resp to error out w/o completing the task completion, eventually causing LUN RESET to be escalated to host reset, which is not very nice. Per FCP-3 r04, clause 9.5.15 and Table 23, the FCP_RSP_INFO field can be either 4 bytes or 8 bytes, with the last 4 bytes as "Reserved (if any)". Therefore it is valid to have 4 bytes FCP_RSP_INFO like some of the NetApp targets behave. Fixing this by validating the FCP_RSP_INFO against both the two spec allowed length.

This patch adds support for Fabric Device Management Interface as per FC-GS-4 spec. in libfc. Any driver making use of libfc can enable fdmi state machine for a given lport. If lport has enabled FDMI support the lport state machine will transition into FDMI after completing the DNS states and before entering the SCR state. The FDMI state transition is such that if there is an error, it won't stop the lport state machine from transitioning and the it will behave as if there was no FDMI support. The FDMI HBA attributes are registed with the Management server via Register HBA (RHBA) command and the port attributes are reigstered using the Register Port(RPA) command.

The FC-BB-6 committee is proposing a new FIP usage model called VN_port to VN_port mode. It allows VN_ports to discover each other over a loss-free L2 Ethernet without any FCF or Fibre-channel fabric services. This is point-to-multipoint. There is also a variant of this called point-to-point which provides for making sure there is just one pair of ports operating over the Ethernet fabric. This patch defines the new message type and subtypes as well as one new descriptor type used by VN2VN mode. These are all still at the proposed stage and subject to change.

2009-09-10[SCSI] libfc: fix: empty zone causes endless discovery retries.Joe Eykholt1-0/+1
On some switches, an empty zone causes GPN_FT to be rejected with reason 9 (unable) explanation 7 (FC-4 types not registered), which causes discovery to be retried endlessly. Treat this as just an empty response and consider discovery complete.

2009-04-27[SCSI] libfc: Fix compilation warnings with allmodconfigRobert Love1-0/+1
When building with a .config generated from 'make allmodconfig' some build warnings are generated. This patch corrects the warnings, adds a FC_FID_NONE (= 0) enumeration for FC-IDs and cleans up one variable naming to meet our variable naming conventions. For example, fc_lport's should be named "lport," not "lp." Signed-off-by: Robert Love <robert.w.love@intel.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

This adds eth type ETH_P_FCOE for Fibre Channel over Ethernet (FCoE), consequently, the ETH_P_FCOE from fc_fcoe.h and fcoe skb->protocol is not set as ETH_P_FCOE.

2009-03-06[SCSI] libfc: rport retry on LS_RJT from certain ELSChris Leech1-0/+5
This allows any rport ELS to retry on LS_RJT. The rport error handling would only retry on resource allocation failures and exchange timeouts. I have a target that will occasionally reject PLOGI when we do a quick LOGO/PLOGI. When a critical ELS was rejected, libfc would fail silently leaving the rport in a dead state. The retry count and delay are managed by fc_rport_error_retry. If the retry count is exceeded fc_rport_error will be called. When retrying is not the correct course of action, fc_rport_error can be called directly.
