2024-09-04rpmb: fix error path in rpmb_dev_register()Jens Wiklander1-6/+4
Until this patch was rpmb_dev_register() always freeing rdev in the error path. However, past device_register() it must not do that since the memory is now managed by the device even if it failed to register properly. So fix this by doing a put_device() before returning the error code. Fixes the smatch warning: drivers/misc/rpmb-core.c:204 rpmb_dev_register() warn: freeing device managed memory (leak): 'rdev' Fixes: 1e9046e3a154 ("rpmb: add Replay Protected Memory Block (RPMB) subsystem") Reported-by: Dan Carpenter <[email protected]> Signed-off-by: Jens Wiklander <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Ulf Hansson <[email protected]>

Prevent build error when CONFIG_RPMB=m and CONFIG_OPTEE=y by adding a dependency to CONFIG_RPMB for CONFIG_OPTEE so the RPMB subsystem always is reachable if configured. This means that CONFIG_OPTEE automatically becomes compiled as a module if CONFIG_RPMB is compiled as a module.

simple_strtoul() is obsolete and lacks proper error handling, making it unsafe for converting strings to unsigned long values. Replace it with kstrtoul(), which provides robust error checking and better safety. This change improves the reliability of the string-to-integer conversion and aligns with current kernel coding standards.

2024-08-28mmc: dw_mmc: Fix IDMAC operation with pages bigger than 4KSam Protsenko1-2/+2
Commit 616f87661792 ("mmc: pass queue_limits to blk_mq_alloc_disk") [1] revealed the long living issue in dw_mmc.c driver, existing since the time when it was first introduced in commit f95f3850f7a9 ("mmc: dw_mmc: Add Synopsys DesignWare mmc host driver."), also making kernel boot broken on platforms using dw_mmc driver with 16K or 64K pages enabled, with this message in dmesg: mmcblk: probe of mmc0:0001 failed with error -22 That's happening because mmc_blk_probe() fails when it calls blk_validate_limits() consequently, which returns the error due to failed max_segment_size check in this code: /* * The maximum segment size has an odd historic 64k default that * drivers probably should override. Just like the I/O size we * require drivers to at least handle a full page per segment. */ ... if (WARN_ON_ONCE(lim->max_segment_size < PAGE_SIZE)) return -EINVAL; In case when IDMAC (Internal DMA Controller) is used, dw_mmc.c always sets .max_seg_size to 4 KiB: mmc->max_seg_size = 0x1000; The comment in the code above explains why it's incorrect. Arnd suggested setting .max_seg_size to .max_req_size to fix it, which is also what some other drivers are doing: $ grep -rl 'max_seg_size.*=.*max_req_size' drivers/mmc/host/ | \ wc -l 18 This change is not only fixing the boot with 16K/64K pages, but also leads to a better MMC performance. The linear write performance was tested on E850-96 board (eMMC only), before commit [1] (where it's possible to boot with 16K/64K pages without this fix, to be able to do a comparison). It was tested with this command: # dd if=/dev/zero of=somefile bs=1M count=500 oflag=sync Test results are as follows: - 4K pages, .max_seg_size = 4 KiB: 94.2 MB/s - 4K pages, .max_seg_size = .max_req_size = 512 KiB: 96.9 MB/s - 16K pages, .max_seg_size = 4 KiB: 126 MB/s - 16K pages, .max_seg_size = .max_req_size = 2 MiB: 128 MB/s - 64K pages, .max_seg_size = 4 KiB: 138 MB/s - 64K pages, .max_seg_size = .max_req_size = 8 MiB: 138 MB/s Unfortunately, SD card controller is not enabled in E850-96 yet, so it wasn't possible for me to run the test on some cheap SD cards to check this patch's impact on those. But it's possible that this change might also reduce the writes count, thus improving SD/eMMC longevity. All credit for the analysis and the suggested solution goes to Arnd.

2024-08-26rpmb: add Replay Protected Memory Block (RPMB) subsystemJens Wiklander5-0/+374
A number of storage technologies support a specialised hardware partition designed to be resistant to replay attacks. The underlying HW protocols differ but the operations are common. The RPMB partition cannot be accessed via standard block layer, but by a set of specific RPMB commands. Such a partition provides authenticated and replay protected access, hence suitable as a secure storage. The initial aim of this patch is to provide a simple RPMB driver interface which can be accessed by the optee driver to facilitate early RPMB access to OP-TEE OS (secure OS) during the boot time. A TEE device driver can claim the RPMB interface, for example, via rpmb_interface_register() or rpmb_dev_find_device(). The RPMB driver provides a callback to route RPMB frames to the RPMB device accessible via rpmb_route_frames(). The detailed operation of implementing the access is left to the TEE device driver itself.

In this way, sd_read_ext_regs() to has the available information for not assigning the SD_EXT_PERF_CACHE as one of the (un)supported features, which in turn allows mmc_sd_init_card() to properly skip execution of sd_enable_cache().

In addition to the required core clock and optional bus clock, the soc will expand its own clocks, so the bulk clock mechanism is abstracted. Note, I call the bulk clocks as "other clocks" due to the bus clock has been called as "optional".

2024-08-26mmc: renesas_sdhi: Add RZ/V2H(P) compatible stringLad Prabhakar1-0/+1
The SD/MMC block on the RZ/V2H(P) ("R9A09G057") SoC is similar to that of the R-Car Gen3, but it has some differences: - HS400 is not supported. - It has additional SD_STATUS register to control voltage, power enable and reset. - It supports fixed address mode. To accommodate these differences, a SoC-specific 'renesas,sdhi-r9a09g057' compatible string is added. Note for RZ/V2H(P), we are using the `of_rzg2l_compatible` OF data as it already handles no HS400 and fixed address mode support. Since the SDxIOVS and SDxPWEN pins can always be used as GPIO pins on the RZ/V2H(P) SoC, no driver changes are done to control the SD_STATUS register.

There is no need to check for a null mrq->cmd in pxav1_request_done. mmc_request_done already assumes it's not null, and it's always called in this path by every SDHCI driver.
