2023-03-31wifi: brcmfmac: Fix SDIO suspend/resume regressionHans de Goede
After commit 92cadedd9d5f ("brcmfmac: Avoid keeping power to SDIO card unless WOWL is used"), the wifi adapter by default is turned off on suspend and then re-probed on resume. In at least 2 model x86/acpi tablets with brcmfmac43430a1 wifi adapters, the newly added re-probe on resume fails like this: brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout ieee80211 phy1: brcmf_bus_started: failed: -110 ieee80211 phy1: brcmf_attach: dongle is not responding: err=-110 brcmfmac: brcmf_sdio_firmware_callback: brcmf_attach failed It seems this specific brcmfmac model does not like being reprobed without it actually being turned off first. And the adapter is not being turned off during suspend because of commit f0992ace680c ("brcmfmac: prohibit ACPI power management for brcmfmac driver"). Now that the driver is being reprobed on resume, the disabling of ACPI pm is no longer necessary, except when WOWL is used (in which case there is no-reprobe). Move the dis-/en-abling of ACPI pm to brcmf_sdio_wowl_config(), this fixes the brcmfmac43430a1 suspend/resume regression and should help save some power when suspended. This change means that the code now also may re-enable ACPI pm when WOWL gets disabled. ACPI pm should only be re-enabled if it was enabled by the ACPI core originally. Add a brcmf_sdiod_acpi_save_power_manageable() to save the original state for this. This has been tested on the following devices: Asus T100TA brcmfmac43241b4-sdio Acer Iconia One 7 B1-750 brcmfmac43340-sdio Chuwi Hi8 brcmfmac43430a0-sdio Chuwi Hi8 brcmfmac43430a1-sdio (the Asus T100TA is the device for which the prohibiting of ACPI pm was originally added) Fixes: 92cadedd9d5f ("brcmfmac: Avoid keeping power to SDIO card unless WOWL is used") Cc: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20230320122252.240070-1-hdegoede@redhat.com
2023-03-31dmaengine: apple-admac: Fix 'current_tx' not getting freedMartin Povišer
In terminate_all we should queue up all submitted descriptors to be freed. We do that for the content of the 'issued' and 'submitted' lists, but the 'current_tx' descriptor falls through the cracks as it's removed from the 'issued' list once it gets assigned to be the current descriptor. Explicitly queue up freeing of the 'current_tx' descriptor to address a memory leak that is otherwise present.

Currently, intel_speed_mode_2500() will fix-up xpcs_an_inband to 1 if the underlying controller has a max speed of 1000Mbps. The value has been initialized and modified if it is a fixed-linked setup earlier. This patch removes the fix-up to allow for fixed-linked setup support. In stmmac_phy_setup(), ovr_an_inband is set based on the value of xpcs_an_inband. Which in turn will return an error in phylink_parse_mode() where MLO_AN_FIXED and ovr_an_inband are both set.

But it triggers a lockdep warning. - Use the cpuhp_setup_state_multi() to set up a dedicated state for each IOMMU PMU. The lock can be avoided. The latter method is implemented in this patch. Since each IOMMU PMU has a dedicated state, add cpuhp_node and cpu in struct iommu_pmu to track the state. The state can be dynamically allocated now. Remove the CPUHP_AP_PERF_X86_IOMMU_PERF_ONLINE.

2023-03-30dm: fix __send_duplicate_bios() to always allow for splitting IOMike Snitzer
Commit 7dd76d1feec70 ("dm: improve bio splitting and associated IO accounting") only called setup_split_accounting() from __send_duplicate_bios() if a single bio were being issued. But the case where duplicate bios are issued must call it too. Otherwise the bio won't be split and resubmitted (via recursion through block core back to DM) to submit the later portions of a bio (which may map to an entirely different target). For example, when discarding an entire DM striped device with the following DM table: vg-lvol0: 0 159744 striped 2 128 7:0 2048 7:1 2048 vg-lvol0: 159744 45056 striped 2 128 7:2 2048 7:3 2048 Before (broken, discards the first striped target's devices twice): device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872 device-mapper: striped: target_stripe=0, bdev=7:0, start=2049 len=22528 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=22528 After (works as expected): device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872 device-mapper: striped: target_stripe=0, bdev=7:2, start=2048 len=22528 device-mapper: striped: target_stripe=1, bdev=7:3, start=2048 len=22528 Fixes: 7dd76d1feec70 ("dm: improve bio splitting and associated IO accounting") Cc: stable@vger.kernel.org Reported-by: Orange Kao <orange@aiven.io> Signed-off-by: Mike Snitzer <snitzer@kernel.org>
2023-03-30dm: fix improper splitting for abnormal biosMike Snitzer
"Abnormal" bios include discards, write zeroes and secure erase. By no longer passing the calculated 'len' pointer, commit 7dd06a2548b2 ("dm: allow dm_accept_partial_bio() for dm_io without duplicate bios") took a senseless approach to disallowing dm_accept_partial_bio() from working for duplicate bios processed using __send_duplicate_bios(). It inadvertently and incorrectly stopped the use of 'len' when initializing a target's io (in alloc_tio). As such the resulting tio could address more area of a device than it should. For example, when discarding an entire DM striped device with the following DM table: vg-lvol0: 0 159744 striped 2 128 7:0 2048 7:1 2048 vg-lvol0: 159744 45056 striped 2 128 7:2 2048 7:3 2048 Before this fix: device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=102400 blkdiscard: attempt to access beyond end of device loop0: rw=2051, sector=2048, nr_sectors = 102400 limit=81920 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=102400 blkdiscard: attempt to access beyond end of device loop1: rw=2051, sector=2048, nr_sectors = 102400 limit=81920 After this fix; device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872 Fixes: 7dd06a2548b2 ("dm: allow dm_accept_partial_bio() for dm_io without duplicate bios") Cc: stable@vger.kernel.org Reported-by: Orange Kao <orange@aiven.io> Signed-off-by: Mike Snitzer <snitzer@kernel.org>

2023-03-30net: mvneta: fix potential double-frees in mvneta_txq_sw_deinit()Russell King (Oracle)
Reported on the Turris forum, mvneta provokes kernel warnings in the architecture DMA mapping code when mvneta_setup_txqs() fails to allocate memory. This happens because when mvneta_cleanup_txqs() is called in the mvneta_stop() path, we leave pointers in the structure that have been freed. Then on mvneta_open(), we call mvneta_setup_txqs(), which starts allocating memory. On memory allocation failure, mvneta_cleanup_txqs() will walk all the queues freeing any non-NULL pointers - which includes pointers that were previously freed in mvneta_stop(). Fix this by setting these pointers to NULL to prevent double-freeing of the same memory.

When cpumask is specified as a module parameter the value is overwritten by the module init routine. This can easily be fixed by checking to see if the mask has already been allocated in the init routine. When max_idle is specified as a module parameter a panic will occur. The problem is that the idle_injection_cpu_mask is not allocated until the module init routine executes. This can easily be fixed by allocating the cpumask if it's not already allocated.
