scsi: iscsi_tcp: Remove unneeded selections of CRYPTO and CRYPTO_MD5As far as I can tell, CRYPTO_MD5 has been unnecessary here ever since itwas added by commit c899e4ef96f0 ("[SCSI] open-iscsi/linux-iscsi-5Initiator: Kconfig update") in 2005.CRYPTO was needed until commit 92186c1455a2 ("scsi: iscsi_tcp: Switch tousing the crc32c library"), but is no longer needed.Remove these unnecessary kconfig selections.Signed-off-by: Eric Biggers Link: https://patch.msgid.link/20260404203003.33738-1-ebiggers@kernel.orgSigned-off-by: Martin K.

Mon, 16 Mar 2026 23:36:31 +0100

scsi: lpfc: Use the crc32c() functionlpfc_cgn_calc_crc32(data, size, crc) is really just an open-coded versionof ~crc32c(bitrev32(crc), data, size). However, all callers pass crc ==~0, so it can be simplified even further to just ~crc32c(~0, data, size).Remove the crc argument and implement it that way.While we're at it, also use proper types in the function prototype.Signed-off-by: Eric Biggers Link: https://patch.msgid.link/20260316223631.72361-1-ebiggers@kernel.orgSigned-off-by: Martin K.

Tue, 16 Sep 2025 01:46:03 +0200

Drivers: hv: Add CONFIG_HYPERV_VMBUS optionAt present VMBus driver is hinged off of CONFIG_HYPERV which entailslot of builtin code and encompasses too much. It's not always clearwhat depends on builtin hv code and what depends on VMBus. SettingCONFIG_HYPERV as a module and fudging the Makefile to switch to builtinadds even more confusion. VMBus is an independent module and should haveits own config option. Also, there are scenarios like baremetal dom0/rootwhere support is built in with CONFIG_HYPERV but without VMBus. Lastly,there are more features coming down that use CONFIG_HYPERV and add moredependencies on it.So, create a fine grained HYPERV_VMBUS option and update Kconfigs fordependency on VMBus.Signed-off-by: Mukesh Rathor Acked-by: Bjorn Helgaas # drivers/pciSigned-off-by: Wei Liu List of files: /linux/drivers/scsi/Kconfig

scsi: iscsi_tcp: Switch to using the crc32c libraryNow that the crc32c() library function directly takes advantage ofarchitecture-specific optimizations, it is unnecessary to go through thecrypto API.

Thu, 13 Jun 2024 10:48:15 +0200

block: remove the blk_integrity_profile structureBlock layer integrity configuration is a bit complex right now, as itindirects through operation vectors for a simple two-dimensionalconfiguration: a) the checksum type of none, ip checksum, crc, crc64 b) the presence or absence of a reference tagRemove the integrity profile, and instead add a separate csum_type flagwhich replaces the existing ip-checksum field and a new flag thatindicates the presence of the reference tag.This removes up to two layers of indirect calls, remove the need tooffload the no-op verification of non-PI metadata to a workqueue andgenerally simplifies the code. The downside is that block/t10-pi.c nowhas to be built into the kernel when CONFIG_BLK_DEV_INTEGRITY issupported. Given that both nvme and SCSI require t10-pi.ko, it is loadedfor all usual configurations that enabled CONFIG_BLK_DEV_INTEGRITYalready, though.Signed-off-by: Christoph Hellwig Reviewed-by: Kanchan Joshi Reviewed-by: Hannes Reinecke Reviewed-by: Martin K.

Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsiPull more SCSI updates from James Bottomley: "The vfs has long had a write lifetime hint mechanism that gives the expected longevity on storage of the data being written. f2fs was the original consumer of this and used the hint for flash data placement (mostly to avoid write amplification by placing objects with similar lifetimes in the same erase block). More recently the SCSI based UFS (Universal Flash Storage) drivers have wanted to take advantage of this as well, for the same reasons as f2fs, necessitating plumbing the write hints through the block layer and then adding it to the SCSI core. The vfs write_hints already taken plumbs this as far as block and this completes the SCSI core enabling based on a recently agreed reuse of the old write command group number. The additions to the scsi_debug driver are for emulating this property so we can run tests on it in the absence of an actual UFS device"* tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: scsi: scsi_debug: Maintain write statistics per group number scsi: scsi_debug: Implement GET STREAM STATUS scsi: scsi_debug: Implement the IO Advice Hints Grouping mode page scsi: scsi_debug: Allocate the MODE SENSE response from the heap scsi: scsi_debug: Rework subpage code error handling scsi: scsi_debug: Rework page code error handling scsi: scsi_debug: Support the block limits extension VPD page scsi: scsi_debug: Reduce code duplication scsi: sd: Translate data lifetime information scsi: scsi_proto: Add structures and constants related to I/O groups and streams scsi: core: Query the Block Limits Extension VPD page List of files: /linux/drivers/scsi/Kconfig

Mon, 07 Aug 2023 17:52:58 +0200

scsi: ppa: Add a module parameter for the transfer modeI have an Iomega Z100P2 zip drive, but it does not work with my StarTechPEX1P2 AX99100 PCIe parallel port, which evidently does not support 16-bitor 32-bit EPP. Currently the only way to tell the PPA driver to use 8-bitEPP is to write 'mode=3' to /proc/scsi/ppa/*, but the driver doesn'tactually distinguish between the three EPP modes and still tries to use16-bit or 32-bit EPP. And even if writing to that file did make the driveruse 8-bit EPP, it still wouldn't do me any good because by the time thatfile exists, the drive has already failed to initialize.Add a new parameter /sys/module/ppa/mode to set the transfer mode beforeinitializing the drive. This parameter replaces the use ofCONFIG_SCSI_IZIP_EPP16 in the PPA driver.At the same time, default to 8-bit EPP. 16-bit and 32-bit EPP are notnecessary for the drive to function, nor are they part of the IEEE 1284standard, so the driver should not assume that they are available.Signed-off-by: Alex Henrie Link: https://lore.kernel.org/r/20230807155856.362864-2-alexhenrie24@gmail.comSigned-off-by: Martin K.
