| * mmc: rpmb: fixes pause retune on all RPMB partitions.Jorge Ramirez-Ortiz2023-12-071-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When RPMB was converted to a character device, it added support for multiple RPMB partitions (Commit 97548575bef3 ("mmc: block: Convert RPMB to a character device"). One of the changes in this commit was transforming the variable target_part defined in __mmc_blk_ioctl_cmd into a bitmask. This inadvertently regressed the validation check done in mmc_blk_part_switch_pre() and mmc_blk_part_switch_post(), so let's fix it.

* | mmc: core: Use mrq.sbc in close-ended ffuAvri Altman2023-12-071-3/+43
|/ | | | | | | | | | | | | | | | | | | | | | Field Firmware Update (ffu) may use close-ended or open ended sequence. Each such sequence is comprised of a write commands enclosed between 2 switch commands - to and from ffu mode. So for the close-ended case, it will be: cmd6->cmd23-cmd25-cmd6. Some host controllers however, get confused when multi-block rw is sent without sbc, and may generate auto-cmd12 which breaks the ffu sequence. I encountered this issue while testing fwupd (github.com/fwupd/fwupd) on HP Chromebook x2, a qualcomm based QC-7c, code name - strongbad. Instead of a quirk, or hooking the request function of the msm ops, it would be better to fix the ioctl handling and make it use mrq.sbc instead of issuing SET_BLOCK_COUNT separately.

* mmc: block: Do not lose cache flush during CQE error recoveryAdrian Hunter2023-11-141-0/+2
| | | | | | | | | | | | | | | | During CQE error recovery, error-free data commands get requeued if there is any data left to transfer, but non-data commands are completed even though they have not been processed. Requeue them instead. Note the only non-data command is cache flush, which would have resulted in a cache flush being lost if it was queued at the time of CQE recovery.

* mmc: core: Fix error propagation for some ioctl commandsUlf Hansson2023-09-261-11/+20
| | | | | | | | | | | | | | | | | | Userspace has currently no way of checking the internal R1 response error bits for some commands. This is a problem for some commands, like RPMB for example. Typically, we may detect that the busy completion has successfully ended, while in fact the card did not complete the requested operation. To fix the problem, let's always poll with CMD13 for these commands and during the polling, let's also aggregate the R1 response bits. Before completing the ioctl request, let's propagate the R1 response bits too.

* | mmc: block: ensure error propagation for non-blkChristian Loehle2023-05-091-0/+5
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | Requests to the mmc layer usually come through a block device IO. The exceptions are the ioctl interface, RPMB chardev ioctl and debugfs, which issue their own blk_mq requests through blk_execute_rq and do not query the BLK_STS error but the mmcblk-internal drv_op_result. This patch ensures that drv_op_result defaults to an error and has to be overwritten by the operation to be considered successful. The behavior leads to a bug where the request never propagates the error, e.g. by directly erroring out at mmc_blk_mq_issue_rq if mmc_blk_part_switch fails. The ioctl caller of the rpmb chardev then can never see an error (BLK_STS_IOERR, but drv_op_result is unchanged) and thus may assume that their call executed successfully when it did not. While always checking the blk_execute_rq return value would be advised, let's eliminate the error by always setting drv_op_result as -EIO to be overwritten on success (or other error) Fixes: 614f0388f580 ("mmc: block: move single ioctl() commands to block requests") Signed-off-by: Christian Loehle <cloehle@hyperstone.com> Acked-by: Adrian Hunter <adrian.hunter@intel.com> Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/59c17ada35664b818b7bd83752119b2d@hyperstone.com Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

| | | | | | | | | | | | | | | | | | | | | The workaround of pretending R1B non-data transfers are data transfers in order for the busy timeout to be respected by the host controller driver is removed. It wasn't useful in a long time. Initially the workaround ensured that R1B commands did not time out by setting the data timeout to be the command timeout in commit cb87ea28ed9e ("mmc: core: Add mmc CMD+ACMD passthrough ioctl"). This was moved inside an if-clause with idata->buf_bytes being set in commit 4d6144de8ba2 ("mmc: core: check for zero length ioctl data"). Since the workaround is now inside the idata->buf_bytes clause and intended to fix R1B non-data transfers, that do not have buf_bytes set, we can remove the workaround altogether. This was dead code, since data transfers doesn't use R1B commands.

* mmc: block: Fix CQE recovery reset successAdrian Hunter2022-06-011-2/+1
| | | | | | | | | | | | | | | | | | The intention of the use of mmc_blk_reset_success() in mmc_blk_cqe_recovery() was to prevent repeated resets when retrying and getting the same error. However, that may not be the case - any amount of time and I/O may pass before another recovery is needed, in which case there would be no reason to deny it the opportunity to recover via a reset if necessary. CQE recovery is expected seldom and failure to recover (if the clear tasks command fails), even more seldom, so it is better to allow the reset always, which can be done by calling mmc_blk_reset_success() always.

| | | | | | | | | | | | | | | | | | Despite mmc_ioc_multi_cmd::num_of_cmds is a 64-bit field, its maximum value is limited to MMC_IOC_MAX_CMDS (only 255); using a 64-bit local variable to hold a copy of that field leads to gcc generating ineffective loop code: despite the source code using an *int* variable for the loop counters, the 32-bit object code uses 64-bit unsigned counters. Also, gcc has to drop the most significant word of that 64-bit variable when calling kcalloc() and assigning to mmc_queue_req::ioc_count anyway. Using the *unsigned int* variable instead results in a better code. Found by Linux Verification Center (linuxtesting.org) with the SVACE static analysis tool.

* mmc: core: Fixup support for writeback-cache for eMMC and SDMichael Wu2022-04-041-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the card initialization process, the mmc core checks whether the eMMC/SD card supports an internal writeback-cache and then enables it inside the card. Unfortunately, this isn't according to what the mmc core reports to the upper block layer. Instead, the writeback-cache support with REQ_FLUSH and REQ_FUA, are being enabled depending on whether the host supports the CMD23 (MMC_CAP_CMD23) and whether an eMMC supports the reliable-write command. This is wrong and it may also sound awkward. In fact, it's a remnant from when both eMMC/SD cards didn't have dedicated commands/support to control the internal writeback-cache. In other words, it was the best we could do at that point in time. To fix the problem, but also without breaking backwards compatibility, let's align the REQ_FLUSH support with whether the writeback-cache became successfully enabled - for both eMMC and SD cards.

* mmc: block: Check for errors after write on SPIChristian Löhle2022-04-041-1/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a SEND_STATUS check for writes through SPI to not mark an unsuccessful write as successful. Since SPI SD/MMC does not have states, after a write, the card will just hold the line LOW until it is ready again. The driver marks the write therefore as completed as soon as it reads something other than all zeroes. The driver does not distinguish from a card no longer signalling busy and it being disconnected (and the line being pulled-up by the host). This lead to writes being marked as successful when disconnecting a busy card. Now the card is ensured to be still connected by an additional CMD13, just like non-SPI is ensured to go back to TRAN state. While at it and since we already poll for the post-write status anyway, we might as well check for SPIs error bits (any of them). The disconnecting card problem is reproducable for me after continuous write activity and randomly disconnecting, around every 20-50 tries on SPI DS for some card.

The purpose was to decrease the total time spent in the busy polling loop, but unfortunate it has lead to problems, that causes eMMC cards to never gets out busy and thus fails to be initialized. To fix the problem, but also to try to keep some of the new improved behaviour, let's start by using a polling period of 1-2ms, which then increases for each loop, according to common polling loop in __mmc_poll_for_busy().

* mmc: block: fix read single on recovery logicChristian Löhle2022-02-081-14/+14
| | | | | | | | | | | | | | | | | | | | | | | | On reads with MMC_READ_MULTIPLE_BLOCK that fail, the recovery handler will use MMC_READ_SINGLE_BLOCK for each of the blocks, up to MMC_READ_SINGLE_RETRIES times each. The logic for this is fixed to never report unsuccessful reads as success to the block layer. On command error with retries remaining, blk_update_request was called with whatever value error was set last to. In case it was last set to BLK_STS_OK (default), the read will be reported as success, even though there was no data read from the device. This could happen on a CRC mismatch for the response, a card rejecting the command (e.g. again due to a CRC mismatch). In case it was last set to BLK_STS_IOERR, the error is reported correctly, but no retries will be attempted.

| * mmc: block: Add error handling support for add_disk()Luis Chamberlain2021-10-121-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | We never checked for errors on add_disk() as this function returned void. Now that this is fixed, use the shiny new error handling. The caller only cleanups the disk if we pass on an allocated md but on error we return return ERR_PTR(ret), and so we must do all the unwinding ourselves.
