2023-01-19accel/ivpu: Add GEM buffer object managementJacek Lawrynowicz-0/+94
Adds four types of GEM-based BOs for the VPU: - shmem - internal - prime All types are implemented as struct ivpu_bo, based on struct drm_gem_object. VPU address is allocated when buffer is created except for imported prime buffers that allocate it in BO_INFO IOCTL due to missing file_priv arg in gem_prime_import callback. Internal buffers are pinned on creation, the rest of buffers types can be pinned on demand (in SUBMIT IOCTL). Buffer VPU address, allocated pages and mappings are released when the buffer is destroyed. Eviction mechanism is planned for future versions. Add two new IOCTLs: BO_CREATE, BO_INFO Signed-off-by: Jacek Lawrynowicz <jacek.lawrynowicz@linux.intel.com> Reviewed-by: Oded Gabbay <ogabbay@kernel.org> Reviewed-by: Jeffrey Hugo <quic_jhugo@quicinc.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20230117092723.60441-4-jacek.lawrynowicz@linux.intel.com
2023-01-19accel/ivpu: Add Intel VPU MMU supportJacek Lawrynowicz-0/+4
VPU Memory Management Unit is based on ARM MMU-600. It allows the creation of multiple virtual address spaces for the device and map noncontinuous host memory (there is no dedicated memory on the VPU). Address space is implemented as a struct ivpu_mmu_context, it has an ID, drm_mm allocator for VPU addresses and struct ivpu_mmu_pgtable that holds actual 3-level, 4KB page table. Context with ID 0 (global context) is created upon driver initialization and it's mainly used for mapping memory required to execute the firmware. Contexts with non-zero IDs are user contexts allocated each time the devices is open()-ed and they map command buffers and other workload-related memory. Workloads executing in a given contexts have access only to the memory mapped in this context. This patch is has two main files: - ivpu_mmu_context.c handles MMU page tables and memory mapping - ivpu_mmu.c implements a driver that programs the MMU device Co-developed-by: Karol Wachowski <karol.wachowski@linux.intel.com> Signed-off-by: Karol Wachowski <karol.wachowski@linux.intel.com> Co-developed-by: Krystian Pradzynski <krystian.pradzynski@linux.intel.com> Signed-off-by: Krystian Pradzynski <krystian.pradzynski@linux.intel.com> Signed-off-by: Jacek Lawrynowicz <jacek.lawrynowicz@linux.intel.com> Reviewed-by: Oded Gabbay <ogabbay@kernel.org> Reviewed-by: Jeffrey Hugo <quic_jhugo@quicinc.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20230117092723.60441-3-jacek.lawrynowicz@linux.intel.com
2023-01-19accel/ivpu: Introduce a new DRM driver for Intel VPUJacek Lawrynowicz-0/+95
VPU stands for Versatile Processing Unit and it's a CPU-integrated inference accelerator for Computer Vision and Deep Learning applications. The VPU device consist of following components: - Buttress - provides CPU to VPU integration, interrupt, frequency and power management. - Memory Management Unit (based on ARM MMU-600) - translates VPU to host DMA addresses, isolates user workloads. - RISC based microcontroller - executes firmware that provides job execution API for the kernel-mode driver - Neural Compute Subsystem (NCS) - does the actual work, provides Compute and Copy engines. - Network on Chip (NoC) - network fabric connecting all the components This driver supports VPU IP v2.7 integrated into Intel Meteor Lake client CPUs (14th generation). Module sources are at drivers/accel/ivpu and module name is "intel_vpu.ko". This patch includes only very besic functionality: - module, PCI device and IRQ initialization - register definitions and low level register manipulation functions - SET/GET_PARAM ioctls - power up without firmware Co-developed-by: Krystian Pradzynski <krystian.pradzynski@linux.intel.com> Signed-off-by: Krystian Pradzynski <krystian.pradzynski@linux.intel.com> Signed-off-by: Jacek Lawrynowicz <jacek.lawrynowicz@linux.intel.com> Reviewed-by: Oded Gabbay <ogabbay@kernel.org> Reviewed-by: Jeffrey Hugo <quic_jhugo@quicinc.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20230117092723.60441-2-jacek.lawrynowicz@linux.intel.com

2023-01-18mm/memfd: add MFD_NOEXEC_SEAL and MFD_EXECJeff Xu-0/+4
The new MFD_NOEXEC_SEAL and MFD_EXEC flags allows application to set executable bit at creation time (memfd_create). When MFD_NOEXEC_SEAL is set, memfd is created without executable bit (mode:0666), and sealed with F_SEAL_EXEC, so it can't be chmod to be executable (mode: 0777) after creation. when MFD_EXEC flag is set, memfd is created with executable bit (mode:0777), this is the same as the old behavior of memfd_create. The new pid namespaced sysctl vm.memfd_noexec has 3 values: 0: memfd_create() without MFD_EXEC nor MFD_NOEXEC_SEAL acts like MFD_EXEC was set. 1: memfd_create() without MFD_EXEC nor MFD_NOEXEC_SEAL acts like MFD_NOEXEC_SEAL was set. 2: memfd_create() without MFD_NOEXEC_SEAL will be rejected. The sysctl allows finer control of memfd_create for old-software that doesn't set the executable bit, for example, a container with vm.memfd_noexec=1 means the old-software will create non-executable memfd by default. Also, the value of memfd_noexec is passed to child namespace at creation time. For example, if the init namespace has vm.memfd_noexec=2, all its children namespaces will be created with 2.

2023-01-18mm/memfd: add F_SEAL_EXECDaniel Verkamp-0/+1
Patch series "mm/memfd: introduce MFD_NOEXEC_SEAL and MFD_EXEC", v8. Since Linux introduced the memfd feature, memfd have always had their execute bit set, and the memfd_create() syscall doesn't allow setting it differently. However, in a secure by default system, such as ChromeOS, (where all executables should come from the rootfs, which is protected by Verified boot), this executable nature of memfd opens a door for NoExec bypass and enables “confused deputy attack”. E.g, in VRP bug [1]: cros_vm process created a memfd to share the content with an external process, however the memfd is overwritten and used for executing arbitrary code and root escalation. [2] lists more VRP in this kind. On the other hand, executable memfd has its legit use, runc uses memfd’s seal and executable feature to copy the contents of the binary then execute them, for such system, we need a solution to differentiate runc's use of executable memfds and an attacker's [3]. To address those above, this set of patches add following: 1> Let memfd_create() set X bit at creation time. 2> Let memfd to be sealed for modifying X bit. 3> A new pid namespace sysctl: vm.memfd_noexec to control the behavior of X bit.For example, if a container has vm.memfd_noexec=2, then memfd_create() without MFD_NOEXEC_SEAL will be rejected. 4> A new security hook in memfd_create(). This make it possible to a new LSM, which rejects or allows executable memfd based on its security policy. This patch (of 5): The new F_SEAL_EXEC flag will prevent modification of the exec bits: written as traditional octal mask, 0111, or as named flags, S_IXUSR | S_IXGRP | S_IXOTH. Any chmod(2) or similar call that attempts to modify any of these bits after the seal is applied will fail with errno EPERM. This will preserve the execute bits as they are at the time of sealing, so the memfd will become either permanently executable or permanently un-executable.

Introduce NFT_MSG_DESTROY* message type. The destroy operation performs a delete operation but ignoring the ENOENT errors. This is useful for the transaction semantics, where failing to delete an object which does not exist results in aborting the transaction.

2023-01-17sched: add new attr TCA_EXT_WARN_MSG to report tc extact messageHangbin Liu-0/+1
We will report extack message if there is an error via netlink_ack(). But if the rule is not to be exclusively executed by the hardware, extack is not passed along and offloading failures don't get logged. In commit 81c7288b170a ("sched: cls: enable verbose logging") Marcelo made cls could log verbose info for offloading failures, which helps improving Open vSwitch debuggability when using flower offloading. It would also be helpful if userspace monitor tools, like "tc monitor", could log this kind of message, as it doesn't require vswitchd log level adjusment. Let's add a new tc attributes to report the extack message so the monitor program could receive the failures. e.g. # tc monitor added chain dev enp3s0f1np1 parent ffff: chain 0 added filter dev enp3s0f1np1 ingress protocol all pref 49152 flower chain 0 handle 0x1 ct_state +trk+new not_in_hw action order 1: gact action drop random type none pass val 0 index 1 ref 1 bind 1 Warning: mlx5_core: matching on ct_state +new isn't supported. In this patch I only report the extack message on add/del operations. It doesn't look like we need to report the extack message on get/dump operations. Note this message not only reporte to multicast groups, it could also be reported unicast, which may affect the current usersapce tool's behaivor.

2022-12-30Merge patch series "UFS Advanced RPMB"Martin K. Petersen-2/+46
Bean Huo <beanhuo@iokpp.de> says: This series of changes is to add support for UFS advanced RPMB in ufs_bsg. The advanced RPMB application of user space is ufs_utils, the reference code is at: https://github.com/beanhuo/ufs-utils-Micron/blob/ufs_arpmb/ufs_arpmb.c. Changes to ufs_utils will be pushed to: https://github.com/westerndigitalcorporation/ufs-utils Link: https://lore.kernel.org/r/20221201140437.549272-1-beanhuo@iokpp.de Signed-off-by: Martin K.

2022-12-30scsi: ufs: core: bsg: Add advanced RPMB support in ufs_bsgBean Huo-1/+45
Add advanced RPMB support in ufs_bsg: 1. According to the UFS specification, only one RPMB operation can be performed at any time. We can ensure this by using reserved slot and its dev_cmd sync operation protection mechanism. 2. For Advanced RPMB, RPMB metadata is packaged in an EHS (Extra Header Segment) of a command UPIU, and the corresponding reply EHS (from the device) should also be returned to the user space. bsg_job->request and bsg_job->reply allow us to pass and return EHS from/back to userspace. Compared to normal/legacy RPMB, the advantages of advanced RPMB are: 1. The data length in the Advanced RPMB data read/write command can be larger than 4KB. For the legacy RPMB, the data length in a single RPMB data transfer is 256 bytes. 2. All of the advanced RPMB operations will be a single command. For legacy RPMB, take the read write-counter value as an example, you need two commands (first SECURITY PROTOCOL OUT, then second SECURITY PROTOCOL IN).
