Adding a "secure" version of STM32 boards (DK1/DK2/ED1/EV1), SCMI (clock/ reset) protocol and OP-TEE node have been added in SoC dtsi file (stm32mp151.dtsi). They have been added with a status disabled in order to keep our legacy unchanged. It is actually not enough to keep our legacy unchanged. First, just a reminder about our use case: TF-A (BL2) loads and starts OP-TEE, then loads and runs U-Boot. U-Boot code checks if an OP-TEE is running, if yes it searches in Kernel device tree if an OP-TEE node is present: -If the OP-TEE node is not present then U-Boot copies OP-TEE node and its reserved memory region from U-Boot device tree to the kernel device tree. -If the OP-TEE node is present then it does nothing (this OP-TEE node will be used by Linux). So U-Boot lets the kernel device tree unchanged thinking it is correct for an OP-TEE usage. It is the case for our legacy boards, the OP-TEE node is present (although disabled) but the reserved memory region is not declared. As no memory region has been reserved for OP-TEE, the end of DDR is seen by the kernel as free and then used for CMA. But as OP-TEE is running, this end of DDR is already used by OP-TEE. So as soon as kernel tries to access to the CMA region OP-TEE raises an error. To fix it, all OP-TEE node and SCMI is moved in a dedicated file.

Merge tag 'scmi-fixes-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/fixes Arm SCMI firmware driver fixes for v5.19 Bunch of fixes to address: 1. Issues reported on RK3568 EVB1 and BPI-R2 pro platforms using SCMI. More checks were added to validate the firmware response but that resulted in breaking above platforms, so the checks are relaxed when for cases where there is no potential memory corruption issues. 2. Possible data leak by reading more than required length from the firmware. Recent addition of support for v3.1 extended names used larger buffers in the kernel and used their size to read response from the firmware even for cases where shorter formats are used. While that is mostly harmless except when firmware sends malformed non-NULL terminated buffers. 3. Possible issues sending unsupported commands to the firmware. SENSOR_AXIS_NAME_GET added in v3.1 needs to be used only if the firmware supports it. While the firmware conformant to the spec must return not supported error for any unsupported features, it is always safer to avoid issuing commands that are known to be unsupported. 4. Incorrect error propagation in scmi_voltage_descriptors_get. Since the return value is not reset for each iteration of the loop, the error value in the previous iteration will be carried for the current one. Fix that by not saving the return values into local variable. 5. Some warnings reported by cppcheck * tag 'scmi-fixes-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_scmi: Fix incorrect error propagation in scmi_voltage_descriptors_get firmware: arm_scmi: Avoid using extended string-buffers sizes if not necessary firmware: arm_scmi: Fix SENSOR_AXIS_NAME_GET behaviour when unsupported firmware: arm_scmi: Remove all the unused local variables firmware: arm_scmi: Relax base protocol sanity checks on the protocol list Link: https://lore.kernel.org/r/20220614100007.1029881-1-sudeep.holla@arm.com Signed-off-by:

Contrary to what was believed at the time, the ramp delay of 150us is not plenty for the PU LDO with the default step time of 512 pulses of the 24MHz clock. Measurements have shown that after enabling the LDO the voltage on VDDPU_CAP jumps to ~750mV in the first step and after that the regulator executes the normal ramp up as defined by the step size control. This means it takes the regulator between 360us and 370us to ramp up to the nominal 1.15V voltage for this power domain. With the old setting of the ramp delay the power up of the PU GPC domain would happen in the middle of the regulator ramp with the voltage being at around 900mV. Apparently this was enough for most units to properly power up the peripherals in the domain and execute the reset. Some units however, fail to power up properly, especially when the chip is at a low temperature. In that case any access to the GPU registers would yield an incorrect result with no way to recover from this situation. Change the ramp delay to 380us to cover the measured ramp up time with a bit of additional slack.

scmi_voltage_descriptors_get() will incorrecly return an error code if the last iteration of the for loop that retrieves the descriptors is skipped due to an error. Skipping an iteration in the loop is not an error, but the `ret` value from the last iteration will be propagated when the function returns. Fix by not saving return values that should not be propagated. This solution also minimizes the risk of future patches accidentally re-introducing this bug.

Pull random number generator fixes from Jason Donenfeld: - A fix for a 5.19 regression for a case in which early device tree initializes the RNG, which flips a static branch. On most plaforms, jump labels aren't initialized until much later, so this caused splats. On a few mailing list threads, we cooked up easy fixes for arm64, arm32, and risc-v. But then things looked slightly more involved for xtensa, powerpc, arc, and mips. And at that point, when we're patching 7 architectures in a place before the console is even available, it seems like the cost/risk just wasn't worth it. So random.c works around it now by checking the already exported `static_key_initialized` boolean, as though somebody already ran into this issue in the past. I'm not super jazzed about that; it'd be prettier to not have to complicate downstream code. But I suppose it's practical. - A few small code nits and adding a missing __init annotation. - A change to the default config values to use the cpu and bootloader's seeds for initializing the RNG earlier. This brings them into line with what all the distros do (Fedora/RHEL, Debian, Ubuntu, Gentoo, Arch, NixOS, Alpine, SUSE, and Void... at least), and moreover will now give us test coverage in various test beds that might have caught the above device tree bug earlier. - A change to WireGuard CI's configuration to increase test coverage around the RNG. - A documentation comment fix to unrelated maintainerless CRC code that I was asked to take, I guess because it has to do with polynomials (which the RNG thankfully no longer uses). * tag 'random-5.19-rc2-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: wireguard: selftests: use maximum cpu features and allow rng seeding random: remove rng_has_arch_random() random: credit cpu and bootloader seeds by default random: do not use jump labels before they are initialized random: account for arch randomness in bits random: mark bootloader randomness code as __init random: avoid checking crng_ready() twice in random_init() crc-itu-t: fix typo in CRC ITU-T polynomial comment

WMI queries fail on some devices where the ACPI method HWMC unconditionally attempts to create Fields beyond the buffer if the buffer is too small, this breaks essential features such as power profiles: CreateByteField (Arg1, 0x10, D008) CreateByteField (Arg1, 0x11, D009) CreateByteField (Arg1, 0x12, D010) CreateDWordField (Arg1, 0x10, D032) CreateField (Arg1, 0x80, 0x0400, D128) In cases where args->data had zero length, ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D008] at bit offset/length 128/8 exceeds size of target Buffer (128 bits) (20211217/dsopcode-198) was obtained. ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D009] at bit offset/length 136/8 exceeds size of target Buffer (136bits) (20211217/dsopcode-198) The original code created a buffer size of 128 bytes regardless if the WMI call required a smaller buffer or not. This particular behavior occurs in older BIOS and reproduced in OMEN laptops. Newer BIOS handles buffer sizes properly and meets the latest specification requirements. This is the reason why testing with a dynamically allocated buffer did not uncover any failures with the test systems at hand. This patch was tested on several OMEN, Elite, and Zbooks. It was confirmed the patch resolves HPWMI_FAN GET/SET calls in an OMEN Laptop 15-ek0xxx. No problems were reported when testing on several Elite and Zbooks notebooks.

Commit 6c776766 ("iov_iter: Fix iter_xarray_get_pages{,_alloc}()") introduced a problem on some 32-bit architectures (at least arm, xtensa, csky,sparc and mips), that have a 'size_t' that is 'unsigned int'. The reason is that we now do min(nr * PAGE_SIZE - offset, maxsize); where 'nr' and 'offset' and both 'unsigned int', and PAGE_SIZE is 'unsigned long'. As a result, the normal C type rules means that the first argument to 'min()' ends up being 'unsigned long'. In contrast, 'maxsize' is of type 'size_t'. Now, 'size_t' and 'unsigned long' are always the same physical type in the kernel, so you'd think this doesn't matter, and from an actual arithmetic standpoint it doesn't. But on 32-bit architectures 'size_t' is commonly 'unsigned int', even if it could also be 'unsigned long'. In that situation, both are unsigned 32-bit types, but they are not the *same* type. And as a result 'min()' will complain about the distinct types (ignore the "pointer types" part of the error message: that's an artifact of the way we have made 'min()' check types for being the same): lib/iov_iter.c: In function 'iter_xarray_get_pages': include/linux/minmax.h:20:35: error: comparison of distinct pointer types lacks a cast [-Werror] 20 | (!!(sizeof((typeof(x) *)1 == (typeof(y) *)1))) | ^~ lib/iov_iter.c:1464:16: note: in expansion of macro 'min' 1464 | return min(nr * PAGE_SIZE - offset, maxsize); | ^~~ This was not visible on 64-bit architectures (where we always define 'size_t' to be 'unsigned long'). Force these cases to use 'min_t(size_t, x, y)' to make the type explicit and avoid the issue. [ Nit-picky note: technically 'size_t' doesn't have to match 'unsigned long' arithmetically. We've certainly historically seen environments with 16-bit address spaces and 32-bit 'unsigned long'. Similarly, even in 64-bit modern environments, 'size_t' could be its own type distinct from 'unsigned long', even if it were arithmetically identical. So the above type commentary is only really descriptive of the kernel environment, not some kind of universal truth for the kinds of wild and crazy situations that are allowed by the C standard ] Reported-by:

The probe function pmt_crashlog_probe() may incorrectly reference the 'priv->entry array' as it uses 'i' to reference the array instead of 'priv->num_entries' as it should.

The maths at the end of iter_xarray_get_pages() to calculate the actual size doesn't work under some circumstances, such as when it's been asked to extract a partial single page. Various terms of the equation cancel out and you end up with actual == offset. The same issue exists in iter_xarray_get_pages_alloc(). Fix these to just use min() to select the lesser amount from between the amount of page content transcribed into the buffer, minus the offset, and the size limit specified. This doesn't appear to have caused a problem yet upstream because network filesystems aren't getting the pages from an xarray iterator, but rather passing it directly to the socket, which just iterates over it. Cachefiles *does* do DIO from one to/from ext4/xfs/btrfs/etc. but it always asks for whole pages to be written or read. Fixes: 7ff50620 ("iov_iter: Add ITER_XARRAY") Reported-by:

The netfs_io_request cleanup op is now always in a position to be given a pointer to a netfs_io_request struct, so this can be passed in instead of the mapping and private data arguments (both of which are included in the struct). So rename the ->cleanup op to ->free_request (to match ->init_request) and pass in the I/O pointer. Signed-off-by:

Change the signature of netfs helper functions to take a struct netfs_inode pointer rather than a struct inode pointer where appropriate, thereby relieving the need for the network filesystem to convert its internal inode format down to the VFS inode only for netfslib to bounce it back up. For type safety, it's better not to do that (and it's less typing too). Give netfs_write_begin() an extra argument to pass in a pointer to the netfs_inode struct rather than deriving it internally from the file pointer. Note that the ->write_begin() and ->write_end() ops are intended to be replaced in the future by netfslib code that manages this without the need to call in twice for each page. netfs_readpage() and similar are intended to be pointed at directly by the address_space_operations table, so must stick to the signature dictated by the function pointers there.
