2023-09-25iommu/tegra-gart: Remove tegra-gartJason Gunthorpe1-26/+0
Thierry says this is not used anymore, and doesn't think it makes sense as an iommu driver. The HW it supports is about 10 years old now and newer HW uses different IOMMU drivers. As this is the only driver with a GART approach, and it doesn't really meet the driver expectations from the IOMMU core, let's just remove it so we don't have to think about how to make it fit in. It has a number of identified problems: - The assignment of iommu_groups doesn't match the HW behavior - It claims to have an UNMANAGED domain but it is really an IDENTITY domain with a translation aperture. This is inconsistent with the core expectation for security sensitive operations - It doesn't implement a SW page table under struct iommu_domain so * It can't accept a map until the domain is attached * It forgets about all maps after the domain is detached * It doesn't clear the HW of maps once the domain is detached (made worse by having the wrong groups) Cc: Thierry Reding <[email protected]> Cc: Dmitry Osipenko <[email protected]> Acked-by: Thierry Reding <[email protected]> Reviewed-by: Lu Baolu <[email protected]> Reviewed-by: Jerry Snitselaar <[email protected]> Signed-off-by: Jason Gunthorpe <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Joerg Roedel <[email protected]>
2023-09-25iommu: Add IOMMU_DOMAIN_PLATFORMJason Gunthorpe1-0/+8
This is used when the iommu driver is taking control of the dma_ops, currently only on S390 and power spapr. It is designed to preserve the original ops->detach_dev() semantic that these S390 was built around. Provide an opaque domain type and a 'default_domain' ops value that allows the driver to trivially force any single domain as the default domain. Update iommufd selftest to use this instead of set_platform_dma_ops Reviewed-by: Lu Baolu <[email protected]> Reviewed-by: Jerry Snitselaar <[email protected]> Signed-off-by: Jason Gunthorpe <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Joerg Roedel <[email protected]>
2023-09-25iommu: Add iommu_ops->identity_domainJason Gunthorpe1-0/+3
This allows a driver to set a global static to an IDENTITY domain and the core code will automatically use it whenever an IDENTITY domain is requested. By making it always available it means the IDENTITY can be used in error handling paths to force the iommu driver into a known state. Devices implementing global static identity domains should avoid failing their attach_dev ops. To make global static domains simpler allow drivers to omit their free function and update the iommufd selftest. Convert rockchip to use the new mechanism.

2023-09-25wifi: cfg80211: report per-link errors during associationBenjamin Berg1-0/+3
When one of the links (other than the assoc_link) is misconfigured and cannot work the association will fail. However, userspace was not able to tell that the operation only failed because of a problem with one of the links. Fix this, by allowing the driver to set a per-link error code and reporting the (first) offending link by setting the bad_attr accordingly. This only allows us to report the first error, but that is sufficient for userspace to e.g. remove the offending link and retry.

2023-09-25wifi: mac80211: support antenna control in injectionJohannes Berg2-1/+7
Support antenna control for injection by parsing the antenna radiotap field (which may be presented multiple times) and telling the driver about the resulting antenna bitmap. Of course there's no guarantee the driver will actually honour this, just like any other injection control. If misconfigured, i.e. the injected HT/VHT MCS needs more chains than antennas are configured, the bitmap is reset to zero, indicating no selection. For now this is only set up for two anntenas so we keep more free bits, but that can be trivially extended if any driver implements support for it that can deal with hardware with more antennas.

2023-09-25ata: libata-sata: increase PMP SRST timeout to 10sMatthias Schiffer1-1/+1
On certain SATA controllers, softreset fails after wakeup from S2RAM with the message "softreset failed (1st FIS failed)", sometimes resulting in drives not being detected again. With the increased timeout, this issue is avoided. Instead, "softreset failed (device not ready)" is now logged 1-2 times; this later failure seems to cause fewer problems however, and the drives are detected reliably once they've spun up and the probe is retried. The issue was observed with the primary SATA controller of the QNAP TS-453B, which is an "Intel Corporation Celeron/Pentium Silver Processor SATA Controller [8086:31e3] (rev 06)" integrated in the Celeron J4125 CPU, and the following drives: - Seagate IronWolf ST12000VN0008 - Seagate IronWolf ST8000NE0004 The SATA controller seems to be more relevant to this issue than the drives, as the same drives are always detected reliably on the secondary SATA controller on the same board (an ASMedia 106x) without any "softreset failed" errors even without the increased timeout.

2023-09-24fscrypt: make the bounce page pool opt-in instead of opt-outEric Biggers1-9/+11
Replace FS_CFLG_OWN_PAGES with a bit flag 'needs_bounce_pages' which has the opposite meaning. I.e., filesystems now opt into the bounce page pool instead of opt out. Make fscrypt_alloc_bounce_page() check that the bounce page pool has been initialized. I believe the opt-in makes more sense, since nothing else in fscrypt_operations is opt-out, and these days filesystems can choose to use blk-crypto which doesn't need the fscrypt bounce page pool. Also, I happen to be planning to add two more flags, and I wanted to fix the "FS_CFLG_" name anyway as it wasn't prefixed with "FSCRYPT_".

The regressions arrived in the v6.5 dev cycle and missed the v6.6 merge window due to my personal absences this cycle. The most important fixes are for scenarios where the CXL subsystem fails to parse valid region configurations established by platform firmware. This is important because agreement between OS and BIOS on the CXL configuration is fundamental to implementing "OS native" error handling, i.e. address translation and component failure identification. Other important fixes are a driver load error when the BIOS lets the Linux PCI core handle AER events, but not CXL memory errors. The other fixex might have end user impact, but for now are only known to trigger in our test/emulation environment. Summary: - Fix multiple scenarios where platform firmware defined regions fail to be assembled by the CXL core. - Fix a spurious driver-load failure on platforms that enable OS native AER, but not OS native CXL error handling. - Fix a regression detecting "poison" commands when "security" commands are also defined. - Fix a cxl_test regression with the move to centralize CXL port register enumeration in the CXL core. - Miscellaneous small fixes and cleanups" * tag 'cxl-fixes-6.6-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: cxl/acpi: Annotate struct cxl_cxims_data with __counted_by cxl/port: Fix cxl_test register enumeration regression cxl/region: Refactor granularity select in cxl_port_setup_targets() cxl/region: Match auto-discovered region decoders by HPA range cxl/mbox: Fix CEL logic for poison and security commands cxl/pci: Replace host_bridge->native_aer with pcie_aer_is_native() PCI/AER: Export pcie_aer_is_native() cxl/pci: Fix appropriate checking for _OSC while handling CXL RAS registers

2023-09-22accel/qaic: Add QAIC_DETACH_SLICE_BO IOCTLPranjal Ramajor Asha Kanojiya1-0/+12
Once a BO is attached with slicing configuration that BO can only be used for that particular setting. With this new feature user can detach slicing configuration off an already sliced BO and attach new slicing configuration using QAIC_ATTACH_SLICE_BO. This will support BO recycling. detach_slice_bo() detaches slicing configuration from a BO. This new helper function can also be used in release_dbc() as we are doing the exact same thing.

2023-09-22accel/qaic: Remove ->size field from struct qaic_boPranjal Ramajor Asha Kanojiya1-6/+6
->size field in struct qaic_bo stores user requested buffer size for allocate path or size of the dmabuf(PRIME). Now for allocate path driver allocates a BO of size which is PAGE_SIZE aligned, this size is already stored in base BO structure (struct drm_gem_object). So difference is ->size of struct qaic_bo stores the raw value coming from user and ->size in struct drm_gem_object stores the PAGE_SZIE aligned size. Do not use ->size from struct qaic_bo for any validation or operation instead use ->size from struct drm_gem_object since we already have allocated that much memory then why not use it. Only validate if user is trying to use more then the BO size. This make the driver more flexible. After this change ->size field of struct qaic_bo becomes redundant. Remove it.

2023-09-22x86/speculation, objtool: Use absolute relocations for annotationsFangrui Song1-5/+5
.discard.retpoline_safe sections do not have the SHF_ALLOC flag. These sections referencing text sections' STT_SECTION symbols with PC-relative relocations like R_386_PC32 [0] is conceptually not suitable. Newer LLD will report warnings for REL relocations even for relocatable links [1]: ld.lld: warning: vmlinux.a(drivers/i2c/busses/i2c-i801.o):(.discard.retpoline_safe+0x120): has non-ABS relocation R_386_PC32 against symbol '' Switch to absolute relocations instead, which indicate link-time addresses. In a relocatable link, these addresses are also output section offsets, used by checks in tools/objtool/check.c. When linking vmlinux, these .discard.* sections will be discarded, therefore it is not a problem that R_X86_64_32 cannot represent a kernel address. Alternatively, we could set the SHF_ALLOC flag for .discard.* sections, but I think non-SHF_ALLOC for sections to be discarded makes more sense. Note: if we decide to never support REL architectures (e.g. arm, i386), we can utilize R_*_NONE relocations (.reloc ., BFD_RELOC_NONE, sym), making .discard.* sections zero-sized. That said, the section content waste is 4 bytes per entry, much smaller than sizeof(Elf{32,64}_Rel).

2023-09-21scsi: core: ata: Do no try to probe for CDL on old drivesDamien Le Moal1-0/+3
Some old drives (e.g. an Ultra320 SCSI disk as reported by John) do not seem to execute MAINTENANCE_IN / MI_REPORT_SUPPORTED_OPERATION_CODES commands correctly and hang when a non-zero service action is specified (one command format with service action case in scsi_report_opcode()). Currently, CDL probing with scsi_cdl_check_cmd() is the only caller using a non zero service action for scsi_report_opcode(). To avoid issues with these old drives, do not attempt CDL probe if the device reports support for an SPC version lower than 5 (CDL was introduced in SPC-5). To keep things working with ATA devices which probe for the CDL T2A and T2B pages introduced with SPC-6, modify ata_scsiop_inq_std() to claim SPC-6 version compatibility for ATA drives supporting CDL. SPC-6 standard version number is defined as Dh (= 13) in SPC-6 r09. Fix scsi_probe_lun() to correctly capture this value by changing the bit mask for the second byte of the INQUIRY response from 0x7 to 0xf. include/scsi/scsi.h is modified to add the definition SCSI_SPC_6 with the value 14 (Dh + 1). The missing definitions for the SCSI_SPC_4 and SCSI_SPC_5 versions are also added.

2023-09-21ACPI: APEI: Fix AER info corruption when error status data has multiple sectionsShiju Jose1-0/+4
ghes_handle_aer() passes AER data to the PCI core for logging and recovery by calling aer_recover_queue() with a pointer to struct aer_capability_regs. The problem was that aer_recover_queue() queues the pointer directly without copying the aer_capability_regs data. The pointer was to the ghes->estatus buffer, which could be reused before aer_recover_work_func() reads the data. To avoid this problem, allocate a new aer_capability_regs structure from the ghes_estatus_pool, copy the AER data from the ghes->estatus buffer into it, pass a pointer to the new struct to aer_recover_queue(), and free it after aer_recover_work_func() has processed it.
