* rbd: embed image request in blk-mq pduIlya Dryomov2020-03-301-87/+51
| | | | | | | | | | | Avoid making allocations for !IMG_REQ_CHILD image requests. Only IMG_REQ_CHILD image requests need to be freed now. Move the initial request checks to rbd_queue_rq(). Unfortunately we can't fill the image request and kick the state machine directly from rbd_queue_rq() because ->queue_rq() isn't allowed to block. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
* rbd: acquire header_rwsem just once in rbd_queue_workfn()Ilya Dryomov2020-03-301-28/+31
| | | | | | | | | | Currently header_rwsem is acquired twice: once in rbd_dev_parent_get() when the image request is being created and then in rbd_queue_workfn() to capture mapping_size and snapc. Introduce rbd_img_capture_header() and move image request allocation so that header_rwsem can be acquired just once. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We see multiple issues with the implementation/interface to compute whether a memory block can be offlined (exposed via /sys/devices/system/memory/memoryX/removable) and would like to simplify it (remove the implementation). 1. It runs basically lockless. While this might be good for performance, we see possible races with memory offlining that will require at least some sort of locking to fix. 2. Nowadays, more false positives are possible. No arch-specific checks are performed that validate if memory offlining will not be denied right away (and such check will require locking). For example, arm64 won't allow to offline any memory block that was added during boot - which will imply a very high error rate. Other archs have other constraints. 3. The interface is inherently racy. E.g., if a memory block is detected to be removable (and was not a false positive at that time), there is still no guarantee that offlining will actually succeed. So any caller already has to deal with false positives. 4. It is unclear which performance benefit this interface actually provides. The introducing commit 5c755e9fd813 ("memory-hotplug: add sysfs removable attribute for hotplug memory remove") mentioned "A user-level agent must be able to identify which sections of memory are likely to be removable before attempting the potentially expensive operation." However, no actual performance comparison was included. Known users: - lsmem: Will group memory blocks based on the "removable" property. [1] - chmem: Indirect user. It has a RANGE mode where one can specify removable ranges identified via lsmem to be offlined. However, it also has a "SIZE" mode, which allows a sysadmin to skip the manual "identify removable blocks" step. [2] - powerpc-utils: Uses the "removable" attribute to skip some memory blocks right away when trying to find some to offline+remove. However, with ballooning enabled, it already skips this information completely (because it once resulted in many false negatives). Therefore, the implementation can deal with false positives properly already. [3] According to Nathan Fontenot, DLPAR on powerpc is nowadays no longer driven from userspace via the drmgr command (powerpc-utils). Nowadays it's managed in the kernel - including onlining/offlining of memory blocks - triggered by drmgr writing to /sys/kernel/dlpar. So the affected legacy userspace handling is only active on old kernels. Only very old versions of drmgr on a new kernel (unlikely) might execute slower - totally acceptable. With CONFIG_MEMORY_HOTREMOVE, always indicating "removable" should not break any user space tool. We implement a very bad heuristic now. Without CONFIG_MEMORY_HOTREMOVE we cannot offline anything, so report "not removable" as before. Original discussion can be found in [4] ("[PATCH RFC v1] mm: is_mem_section_removable() overhaul"). Other users of is_mem_section_removable() will be removed next, so that we can remove is_mem_section_removable() completely.

This patch adds a check for such a buggy hardware to prevent any such mistakes again. While working further on the KS8851 driver, it came to light that the KS8851-16MLL is capable of switching bus endianness by a hardware strap, EESK pin. If this strap is incorrect, the IO accesses require such endian swapping as is being reverted by this patch. Such swapping also impacts the performance significantly. Hence, in addition to removing it, detect that the hardware is broken, report to user, and fail to bind with such hardware.

And then, once an attached drive has spun up, substitute the actual parameters reported by the drive. According to the SCSI spec, the device should return a UNIT ATTENTION in case any reported parameters change. But in this case the change is made silently after a small window where default values are reported. Commit a83da8a4509d ("scsi: sd: Optimal I/O size should be a multiple of physical block size") validated the reported optimal I/O size against the physical block size to overcome problems with devices reporting nonsensical transfer sizes. However, this validation did not account for the fact that aforementioned devices will return default values during a brief window during spin-up. The subsequent change in reported characteristics would invalidate the checking that had previously been performed. Unset a previously configured optimal I/O size should the sanity checking fail on subsequent revalidate attempts.

There are also several small code fixes addressing mostly serious issues: - Fix the sunxi rsb bus access to no longer return incorrect data when mixing 8 and 16 bit I/O. - Fix a suspend/resume regression on the OMAP2+ lcdc from a missing quirk in the ti-sysc driver - Fix a NULL pointer access from a race in the fsl dpio driver - Fix a v5.5 regression in the exynos-chipid driver that caused an invalid error code probing the device on non-exynos platforms - Fix an out-of-bounds access in the AMD TEE driver" * tag 'arm-soc-fixes-5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (24 commits) soc: samsung: chipid: Fix return value on non-Exynos platforms arm64: dts: Fix leftover entry-methods for PSCI ARM: dts: exynos: Fix regulator node aliasing on Midas-based boards ARM: dts: oxnas: Fix clear-mask property ARM: dts: bcm283x: Fix vc4's firmware bus DMA limitations ARM: dts: omap5: Add bus_dma_limit for L3 bus ARM: dts: omap4-droid4: Fix lost touchscreen interrupts ARM: dts: dra7: Add bus_dma_limit for L3 bus ARM: bcm2835-rpi-zero-w: Add missing pinctrl name ARM: dts: sun8i: a33: add the new SS compatible dt-bindings: crypto: add new compatible for A33 SS ARM: dts: sun8i: r40: Move SPI device nodes based on address order ARM: dts: sun8i: r40: Fix register base address for SPI2 and SPI3 ARM: dts: sun8i: r40: Move AHCI device node based on address order ARM: dts: imx6: phycore-som: fix arm and soc minimum voltage soc: fsl: dpio: register dpio irq handlers after dpio create tee: amdtee: out of bounds read in find_session() ARM: dts: N900: fix onenand timings bus: ti-sysc: Fix quirk flags for lcdc on am335x ARM: dts: Fix dm814x Ethernet by changing to use rgmii-id mode ...

The consequence is that after this happens the PMIC's regmap will look like this: (0x33 is the high byte from the 16-bit read) % cat /sys/kernel/debug/regmap/sunxi-rsb-3a3/registers 00: 33 01: 33 02: 33 03: 33 04: 33 05: 33 06: 33 07: 33 08: 33 09: 33 0a: 33 0b: 33 0c: 33 0d: 33 0e: 33 [snip] Fix this by masking the result of the read with the correct mask based on the size of the read. There are no 16-bit users in the mainline kernel, so this doesn't need to get into the stable tree.
