2020-09-15efi: efibc: check for efivars write capabilityArd Biesheuvel
Branden reports that commit f88814cc2578c1 ("efi/efivars: Expose RT service availability via efivars abstraction") regresses UEFI platforms that implement GetVariable but not SetVariable when booting kernels that have EFIBC (bootloader control) enabled. The reason is that EFIBC is a user of the efivars abstraction, which was updated to permit users that rely only on the read capability, but not on the write capability. EFIBC is in the latter category, so it has to check explicitly whether efivars supports writes.

2020-09-15clk: samsung: Keep top BPLL mux on Exynos542x enabledMarek Szyprowski
BPLL clock must not be disabled because it is needed for proper DRAM operation. This is normally handled by respective memory devfreq driver, but when that driver is not yet probed or its probe has been deferred the clock might get disabled what causes board hang. Fix this by calling clk_prepare_enable() directly from the clock provider driver.

2020-09-15EDAC/ghes: Check whether the driver is on the safe list correctlyBorislav Petkov
With CONFIG_DEBUG_TEST_DRIVER_REMOVE=y, a system would try to probe, unregister and probe again a driver. When ghes_edac is attempted to be loaded on a system which is not on the safe platforms list, ghes_edac_register() would return early. The unregister counterpart ghes_edac_unregister() would still attempt to unregister and exit early at the refcount test, leading to the refcount underflow below. In order to not do *anything* on the unregister path too, reuse the force_load parameter and check it on that path too, before fumbling with the refcount. ghes_edac: ghes_edac_register: entry ghes_edac: ghes_edac_register: return -ENODEV ------------[ cut here ]------------ refcount_t: underflow; use-after-free.

2020-09-14rndis_host: increase sleep time in the query-response loopOlympia Giannou
Some WinCE devices face connectivity issues via the NDIS interface. They fail to register, resulting in -110 timeout errors and failures during the probe procedure. In this kind of WinCE devices, the Windows-side ndis driver needs quite more time to be loaded and configured, so that the linux rndis host queries to them fail to be responded correctly on time. More specifically, when INIT is called on the WinCE side - no other requests can be served by the Client and this results in a failed QUERY afterwards. The increase of the waiting time on the side of the linux rndis host in the command-response loop leaves the INIT process to complete and respond to a QUERY, which comes afterwards. The WinCE devices with this special "feature" in their ndis driver are satisfied by this fix. Signed-off-by: Olympia Giannou <olympia.giannou@leica-geosystems.com> Signed-off-by: David S.

2020-09-14vgacon: remove software scrollback supportLinus Torvalds
Yunhai Zhang recently fixed a VGA software scrollback bug in commit ebfdfeeae8c0 ("vgacon: Fix for missing check in scrollback handling"), but that then made people look more closely at some of this code, and there were more problems on the vgacon side, but also the fbcon software scrollback. We don't really have anybody who maintains this code - probably because nobody actually _uses_ it any more. Sure, people still use both VGA and the framebuffer consoles, but they are no longer the main user interfaces to the kernel, and haven't been for decades, so these kinds of extra features end up bitrotting and not really being used. So rather than try to maintain a likely unused set of code, I'll just aggressively remove it, and see if anybody even notices. Maybe there are people who haven't jumped on the whole GUI badnwagon yet, and think it's just a fad. And maybe those people use the scrollback code. If that turns out to be the case, we can resurrect this again, once we've found the sucker^Wmaintainer for it who actually uses it.

2020-09-14Revert "mtd: spi-nor: Disable the flash quad mode in spi_nor_restore()"Yicong Yang
Previous patch intends to restore the flash's QE bit when removed/shutdown, but may have some problems and break the flash: - for those originally in Quad mode, this patch will clear the QE bit when unloaded the flash, which is incorrect. - even with above problem solved, it may still break the flash as some flash's QE bit is non-volatile and lots of set/reset will wear out the bit. - the restore method cannot be proved to be valid as if a hard reset or accident crash happened, the spi_nor_restore() won't be performed the the QE bit will not be restored as we expected to. So let's revert it to fix this. The discussion can be found at [1]. This reverts commit cc59e6bb6cd69d3347c06ccce088c5c6052e041e.

2020-09-11hinic: fix rewaking txq after netif_tx_disableLuo bin
When calling hinic_close in hinic_set_channels, all queues are stopped after netif_tx_disable, but some queue may be rewaken in free_tx_poll by mistake while drv is handling tx irq. If one queue is rewaken core may call hinic_xmit_frame to send pkt after netif_tx_disable within a short time which may results in accessing memory that has been already freed in hinic_close. So we call napi_disable before netif_tx_disable in hinic_close to fix this bug.

2020-09-11spi: spi-fsl-dspi: use XSPI mode instead of DMA for DPAA2 SoCsVladimir Oltean
The arch/arm64/boot/dts/freescale/fsl-ls208xa.dtsi device tree lacks DMA channels for DSPI, so naturally, the driver fails to probe: [ 2.945302] fsl-dspi 2100000.spi: rx dma channel not available [ 2.951134] fsl-dspi 2100000.spi: can't get dma channels In retrospect, this should have been obvious, because LS2080A, LS2085A LS2088A and LX2160A don't appear to have an eDMA module at all. Looking again at their datasheets, the CTARE register (which is specific to XSPI functionality) seems to be documented, so switch them to XSPI mode instead.
