2022-10-21efi: libstub: Remove zboot signing from build optionsArd Biesheuvel2-47/+4
The zboot decompressor series introduced a feature to sign the PE/COFF kernel image for secure boot as part of the kernel build. This was necessary because there are actually two images that need to be signed: the kernel with the EFI stub attached, and the decompressor application. This is a bit of a burden, because it means that the images must be signed on the the same system that performs the build, and this is not realistic for distros. During the next cycle, we will introduce changes to the zboot code so that the inner image no longer needs to be signed. This means that the outer PE/COFF image can be handled as usual, and be signed later in the release process. Let's remove the associated Kconfig options now so that they don't end up in a LTS release while already being deprecated. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
2022-10-21iommu/vt-d: Clean up si_domain in the init_dmars() error pathJerry Snitselaar1-0/+5
A splat from kmem_cache_destroy() was seen with a kernel prior to commit ee2653bbe89d ("iommu/vt-d: Remove domain and devinfo mempool") when there was a failure in init_dmars(), because the iommu_domain cache still had objects. While the mempool code is now gone, there still is a leak of the si_domain memory if init_dmars() fails. So clean up si_domain in the init_dmars() error path.

2022-10-21iommu/vt-d: Use rcu_lock in get_resv_regionsLu Baolu1-3/+3
Commit 5f64ce5411b46 ("iommu/vt-d: Duplicate iommu_resv_region objects per device list") converted rcu_lock in get_resv_regions to dmar_global_lock to allow sleeping in iommu_alloc_resv_region(). This introduced possible recursive locking if get_resv_regions is called from within a section where intel_iommu_init() already holds dmar_global_lock. Especially, after commit 57365a04c921 ("iommu: Move bus setup to IOMMU device registration"), below lockdep splats could always be seen. ============================================ WARNING: possible recursive locking detected 6.0.0-rc4+ #325 Tainted: G I -------------------------------------------- swapper/0/1 is trying to acquire lock: ffffffffa8a18c90 (dmar_global_lock){++++}-{3:3}, at: intel_iommu_get_resv_regions+0x25/0x270 but task is already holding lock: ffffffffa8a18c90 (dmar_global_lock){++++}-{3:3}, at: intel_iommu_init+0x36d/0x6ea ...

Commit 16ce101db85d ("mm/memory.c: fix race when faulting a device private page") changed the migrate_to_ram() callback to take a reference on the device page to ensure it can't be freed while handling the fault.

2022-10-20drm/amdgpu: fix sdma doorbell init ordering on APUsAlex Deucher2-5/+21
Commit 8795e182b02d ("PCI/portdrv: Don't disable AER reporting in get_port_device_capability()") uncovered a bug in amdgpu that required a reordering of the driver init sequence to avoid accessing a special register on the GPU before it was properly set up leading to an PCI AER error. This reordering uncovered a different hw programming ordering dependency in some APUs where the SDMA doorbells need to be programmed before the GFX doorbells. To fix this, move the SDMA doorbell programming back into the soc15 common code, but use the actual doorbell range values directly rather than the values stored in the ring structure since those will not be initialized at this point. This is a partial revert, but with the doorbell assignment fixed so the proper doorbell index is set before it's used.

2022-10-20drbd: only clone bio if we have a backing deviceChristoph Böhmwalder1-8/+6
Commit c347a787e34cb (drbd: set ->bi_bdev in drbd_req_new) moved a bio_set_dev call (which has since been removed) to "earlier", from drbd_request_prepare to drbd_req_new. The problem is that this accesses device->ldev->backing_bdev, which is not NULL-checked at this point. When we don't have an ldev (i.e. when the DRBD device is diskless), this leads to a null pointer deref. So, only allocate the private_bio if we actually have a disk. This is also a small optimization, since we don't clone the bio to only to immediately free it again in the diskless case.

2022-10-20drm/panfrost: replace endian-specific types with native onesSteven Price1-18/+18
__le32 and __le64 types aren't portable and are not available on FreeBSD (which uses the same uAPI). Instead of attempting to always output little endian, just use native endianness in the dumps. Tools can detect the endianness in use by looking at the 'magic' field, but equally we don't expect big-endian to be used with Mali (there are no known implementations out there).

2022-10-20drm/connector: Set DDC pointer in drmm_connector_initMaxime Ripard1-1/+1
Commit 35a3b82f1bdd ("drm/connector: Introduce drmm_connector_init") introduced the function drmm_connector_init() with a parameter for an optional ddc pointer to the i2c controller used to access the DDC bus. However, the underlying call to __drm_connector_init() was always setting it to NULL instead of passing the ddc argument around. This resulted in unexpected null pointer dereference on platforms expecting to get a DDC controller.

2022-10-20drm: tests: Fix a buffer overflow in format_helper_testDavid Gow1-1/+1
The xrgb2101010 format conversion test (unlike for other formats) does an endianness conversion on the results. However, it always converts TEST_BUF_SIZE 32-bit integers, which results in reading from (and writing to) more memory than in present in the result buffer. Instead, use the buffer size, divided by sizeof(u32). The issue could be reproduced with KASAN: ./tools/testing/kunit/kunit.py run --kunitconfig drivers/gpu/drm/tests \ --kconfig_add CONFIG_KASAN=y --kconfig_add CONFIG_KASAN_VMALLOC=y \ --kconfig_add CONFIG_KASAN_KUNIT_TEST=y \ drm_format_helper_test.*xrgb2101010 Reported-by: Linux Kernel Functional Testing <lkft@linaro.org> Fixes: 453114319699 ("drm/format-helper: Add KUnit tests for drm_fb_xrgb8888_to_xrgb2101010()") Signed-off-by: David Gow <davidgow@google.com> Reviewed-by: Maíra Canal <mairacanal@riseup.net> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: José Expósito <jose.exposito89@gmail.com> Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221019073239.3779180-1-davidgow@google.com
