2022-08-19crypto: ccp - Add a quirk to firmware updateJarkko Sakkinen1-2/+14
A quirk for fixing the committed TCB version, when upgrading from a firmware version earlier than 1.50. This is a known issue, and the documented workaround is to load the firmware twice. Currently, this issue requires the following workaround: sudo modprobe -r kvm_amd sudo modprobe -r ccp sudo modprobe ccp sudo modprobe kvm_amd Implement this workaround inside kernel by checking whether the API version is less than 1.50, and if so, download the firmware twice. This addresses the TCB version issue.

2022-08-19crypto: keembay-ocs - Drop obsolete dependency on COMPILE_TESTJean Delvare1-2/+2
Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues.

2022-08-19hwrng: core - let sleep be interrupted when unregistering hwrngJason A. Donenfeld3-5/+20
There are two deadlock scenarios that need addressing, which cause problems when the computer goes to sleep, the interface is set down, and hwrng_unregister() is called. When the deadlock is hit, sleep is delayed for tens of seconds, causing it to fail. These scenarios are: 1) The hwrng kthread can't be stopped while it's sleeping, because it uses msleep_interruptible() which does not react to kthread_stop. 2) A normal user thread can't be interrupted by hwrng_unregister() while it's sleeping, because hwrng_unregister() is called from elsewhere. We solve both issues by add a completion object called dying that fulfils waiters once we have started the process in hwrng_unregister. At the same time, we should cleanup a common and useless dmesg splat in the same area.

2022-08-19crypto: lib - move __crypto_xor into utilsEric Biggers5-76/+90
CRYPTO_LIB_CHACHA depends on CRYPTO for __crypto_xor, defined in crypto/algapi.c. This is a layering violation because the dependencies should only go in the other direction (crypto/ => lib/crypto/). Also the correct dependency would be CRYPTO_ALGAPI, not CRYPTO. Fix this by moving __crypto_xor into the utils module in lib/crypto/. Note that CRYPTO_LIB_CHACHA_GENERIC selected XOR_BLOCKS, which is unrelated and unnecessary. It was perhaps thought that XOR_BLOCKS was needed for __crypto_xor, but that's not the case.

The function qat_uclo_check_image() validates the MMP and AE firmware images. If the QAT device supports firmware authentication (indicated by the handle to firmware loader), the input signed binary MMP and AE images are validated by parsing the following information: - Header length - Full size of the binary - Type of binary image (MMP or AE Firmware) Firmware binaries use RSA3K for signing and verification. The header length for the RSA3k is 0x384 bytes. All the size field values in the binary are quantified as DWORDS (1 DWORD = 4bytes). On an invalid value the function prints an error message and returns with an error code "EINVAL".

MTL introduces a second FBC engine. The two FBC engines can operate entirely independently, FBC A serving pipe A and FBC B serving pipe B. The one place where things might go a bit wrong is the CFB allocation from stolen. We might have to consider some change to the allocation strategy to have a better chance of both engines being able to allocate its CFB. Maybe FBC A should allocate bottom up and FBC B top down, or something? For the moment the allocation strategy is DRM_MM_INSERT_BEST for both.

2022-08-19usb: gadget: udc: renesas_usb3: Add support for RZ/V2MPhil Edworthy1-27/+104
RZ/V2M (r9a09g011) has a few differences: - The USB3_DRD_CON register has moved, its called USB_PERI_DRD_CON in the RZ/V2M hardware manual. It has additional bits for host and peripheral reset that need to cleared to use usb host and peripheral respectively. - The USB3_OTG_STA, USB3_OTG_INT_STA and USB3_OTG_INT_ENA registers have been moved and renamed to USB_PERI_DRD_STA, USB_PERI_DRD_INT_STA and USB_PERI_DRD_INT_E. - The IDMON bit used in the above regs for role detection have moved from bit 4 to bit 0. - RZ/V2M has an separate interrupt for DRD, i.e. for changes to IDMON. - There are reset lines for DRD and USBP - There is another clock, managed by runtime PM. Whilst the hardware can support 16 pipes, it is artifically limited based on the ram per pipe calculation. With the 4KB ram per pipe, we can support 9 pipes consisting of 4xIN pipes, 4xOUT pipes and PIPE0.

Document the RZ/V2M SoC bindings. The RZ/V2M SoC is a little different to the R-Car implementations. A few DRD related registers and bits have moved, there is a separate interrupt for DRD, an additional clock for register access and reset lines for DRD and USBP.
