2023-07-12spi: s3c64xx: clear loopback bit after loopback testJaewon Kim
When SPI loopback transfer is performed, S3C64XX_SPI_MODE_SELF_LOOPBACK bit still remained. It works as loopback even if the next transfer is not spi loopback mode. If not SPI_LOOP, needs to clear S3C64XX_SPI_MODE_SELF_LOOPBACK bit.

2023-07-12mtd: rawnand: meson: fix OOB available bytes for ECCArseniy Krasnov
It is incorrect to calculate number of OOB bytes for ECC engine using some "already known" ECC step size (1024 bytes here). Number of such bytes for ECC engine must be whole OOB except 2 bytes for bad block marker, while proper ECC step size and strength will be selected by ECC logic.

2023-07-12regmap-irq: Fix out-of-bounds access when allocating config buffersIsaac J. Manjarres
When allocating the 2D array for handling IRQ type registers in regmap_add_irq_chip_fwnode(), the intent is to allocate a matrix with num_config_bases rows and num_config_regs columns. This is currently handled by allocating a buffer to hold a pointer for each row (i.e. num_config_bases). After that, the logic attempts to allocate the memory required to hold the register configuration for each row. However, instead of doing this allocation for each row (i.e. num_config_bases allocations), the logic erroneously does this allocation num_config_regs number of times. This scenario can lead to out-of-bounds accesses when num_config_regs is greater than num_config_bases. Fix this by updating the terminating condition of the loop that allocates the memory for holding the register configuration to allocate memory only for each row in the matrix. Amit Pundir reported a crash that was occurring on his db845c device due to memory corruption (see "Closes" tag for Amit's report). The KASAN report below helped narrow it down to this issue: [ 14.033877][ T1] ================================================================== [ 14.042507][ T1] BUG: KASAN: invalid-access in regmap_add_irq_chip_fwnode+0x594/0x1364 [ 14.050796][ T1] Write of size 8 at addr 06ffff8081021850 by task init/1 [ 14.242004][ T1] The buggy address belongs to the object at ffffff8081021850 [ 14.242004][ T1] which belongs to the cache kmalloc-8 of size 8 [ 14.255669][ T1] The buggy address is located 0 bytes inside of [ 14.255669][ T1] 8-byte region [ffffff8081021850, ffffff8081021858) Fixes: faa87ce9196d ("regmap-irq: Introduce config registers for irq types") Reported-by: Amit Pundir <amit.pundir@linaro.org> Closes: https://lore.kernel.org/all/CAMi1Hd04mu6JojT3y6wyN2YeVkPR5R3qnkKJ8iR8if_YByCn4w@mail.gmail.com/ Tested-by: John Stultz <jstultz@google.com> Tested-by: Amit Pundir <amit.pundir@linaro.org> # tested on Dragonboard 845c Cc: stable@vger.kernel.org # v6.0+ Cc: Aidan MacDonald <aidanmacdonald.0x0@gmail.com> Cc: Saravana Kannan <saravanak@google.com> Cc: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: "Isaac J.

2023-07-11wifi: iwlwifi: remove 'use_tfh' config to fix crashJohannes Berg
This is equivalent to 'gen2', and it was always confusing to have two identical config entries. The split config patch actually had been originally developed after removing 'use_tfh" and didn't add the use_tfh in the new configs as they'd later been copied to the new files. Thus the easiest way to fix the init crash here now is to just remove use_tfh (which is erroneously unset in most of the configs now) and use 'gen2' in the code instead. There's possibly still an unwind error in iwl_txq_gen2_init() as it crashes if TXQ 0 fails to initialize, but we can deal with it later since the original failure is due to the use_tfh confusion.

2023-07-11of: Preserve "of-display" device name for compatibilityRob Herring
Since commit 241d2fb56a18 ("of: Make OF framebuffer device names unique"), as spotted by Frédéric Bonnard, the historical "of-display" device is gone: the updated logic creates "of-display.0" instead, then as many "of-display.N" as required. This means that offb no longer finds the expected device, which prevents the Debian Installer from setting up its interface, at least on ppc64el. Fix this by keeping "of-display" for the first device and "of-display.N" for subsequent devices.

2023-07-11scsi: storvsc: Handle SRB status value 0x30Michael Kelley
In response to a disk I/O request, Hyper-V has been observed to return SRB status value 0x30. This indicates the request was not processed by Hyper-V because low memory conditions on the host caused an internal error. The 0x30 status is not recognized by storvsc, so the I/O operation is not flagged as an error. The request is treated as if it completed normally but with zero data transferred, causing a flood of retries. Add a definition for this SRB status value and handle it like other error statuses from the Hyper-V host.

2023-07-11drm/client: Send hotplug event after registering a clientThomas Zimmermann
Generate a hotplug event after registering a client to allow the client to configure its display. Remove the hotplug calls from the existing clients for fbdev emulation. This change fixes a concurrency bug between registering a client and receiving events from the DRM core. The bug is present in the fbdev emulation of all drivers. The fbdev emulation currently generates a hotplug event before registering the client to the device. For each new output, the DRM core sends an additional hotplug event to each registered client. If the DRM core detects first output between sending the artificial hotplug and registering the device, the output's hotplug event gets lost. If this is the first output, the fbdev console display remains dark. This has been observed with amdgpu and fbdev-generic. Fix this by adding hotplug generation directly to the client's register helper drm_client_register(). Registering the client and receiving events are serialized by struct drm_device.clientlist_mutex. So an output is either configured by the initial hotplug event, or the client has already been registered. The bug was originally added in commit 6e3f17ee73f7 ("drm/fb-helper: generic: Call drm_client_add() after setup is done"), in which adding a client and receiving a hotplug event switched order. It was hidden, as most hardware and drivers have at least on static output configured. Other drivers didn't use the internal DRM client or still had struct drm_mode_config_funcs.output_poll_changed set. That callback handled hotplug events as well. After not setting the callback in amdgpu in commit 0e3172bac3f4 ("drm/amdgpu: Don't set struct drm_driver.output_poll_changed"), amdgpu did not show a framebuffer console if output events got lost. The bug got copy-pasted from fbdev-generic into the other fbdev emulation.

If for some reason a external function returns -ENODEV, no error message is being displayed because the driver assumes that -ENODEV can only be returned internally if no sensors, etc where found. Fix this by explicitly returning 0 in such a case since missing hardware is no error. Also remove the now obsolete check for -ENODEV.

GIC700 erratum 2941627 may cause GIC-700 missing SPIs wake requests when SPIs are deactivated while targeting a sleeping CPU - ie a CPU for which the redistributor: GICR_WAKER.ProcessorSleep == 1 This runtime situation can happen if an SPI that has been activated on a core is retargeted to a different core, it becomes pending and the target core subsequently enters a power state quiescing the respective redistributor. When this situation is hit, the de-activation carried out on the core that activated the SPI (through either ICC_EOIR1_EL1 or ICC_DIR_EL1 register writes) does not trigger a wake requests for the sleeping GIC redistributor even if the SPI is pending. Work around the erratum by de-activating the SPI using the redistributor GICD_ICACTIVER register if the runtime conditions require it (ie the IRQ was retargeted between activation and de-activation).

2023-07-11net: fec: use netdev_err_once() instead of netdev_err()Wei Fang
In the case of heavy XDP traffic to be transmitted, the console will print the error log continuously if there are lack of enough BDs to accommodate the frames. The log looks like below. [ 160.013112] fec 30be0000.ethernet eth0: NOT enough BD for SG! [ 160.023116] fec 30be0000.ethernet eth0: NOT enough BD for SG! [ 160.028926] fec 30be0000.ethernet eth0: NOT enough BD for SG!

Not only will this log be replicated and redundant, it will also degrade XDP performance. So we use netdev_err_once() instead of netdev_err() now.

2023-07-11net: fec: increase the size of tx ring and update tx_wake_thresholdWei Fang
When the XDP feature is enabled and with heavy XDP frames to be transmitted, there is a considerable probability that available tx BDs are insufficient. This will lead to some XDP frames to be discarded and the "NOT enough BD for SG!" error log will appear in the console (as shown below). [ 160.013112] fec 30be0000.ethernet eth0: NOT enough BD for SG! [ 160.023116] fec 30be0000.ethernet eth0: NOT enough BD for SG! [ 160.028926] fec 30be0000.ethernet eth0: NOT enough BD for SG! [ 160.038946] fec 30be0000.ethernet eth0: NOT enough BD for SG! [ 160.044758] fec 30be0000.ethernet eth0: NOT enough BD for SG! In the case of heavy XDP traffic, sometimes the speed of recycling tx BDs may be slower than the speed of sending XDP frames. There may be several specific reasons, such as the interrupt is not responsed in time, the efficiency of the NAPI callback function is too low due to all the queues (tx queues and rx queues) share the same NAPI, and so on. After trying various methods, I think that increase the size of tx BD ring is simple and effective. Maybe the best resolution is that allocate NAPI for each queue to improve the efficiency of the NAPI callback, but this change is a bit big and I didn't try this method. Perheps this method will be implemented in a future patch. This patch also updates the tx_wake_threshold of tx ring which is related to the size of tx ring in the previous logic. Otherwise, the tx_wake_threshold will be too high (403 BDs), which is more likely to impact the slow path in the case of heavy XDP traffic, because XDP path and slow path share the tx BD rings. According to Jakub's suggestion, the tx_wake_threshold is at least equal to tx_stop_threshold + 2 * MAX_SKB_FRAGS, if a queue of hundreds of entries is overflowing, we should be able to apply a hysteresis of a few tens of entries.

2023-07-11net: fec: recycle pages for transmitted XDP framesWei Fang
Once the XDP frames have been successfully transmitted through the ndo_xdp_xmit() interface, it's the driver responsibility to free the frames so that the page_pool can recycle the pages and reuse them. However, this action is not implemented in the fec driver. This leads to a user-visible problem that the console will print the following warning log. [ 157.568851] page_pool_release_retry() stalled pool shutdown 1389 inflight 60 sec [ 217.983446] page_pool_release_retry() stalled pool shutdown 1389 inflight 120 sec [ 278.399006] page_pool_release_retry() stalled pool shutdown 1389 inflight 181 sec [ 338.812885] page_pool_release_retry() stalled pool shutdown 1389 inflight 241 sec [ 399.226946] page_pool_release_retry() stalled pool shutdown 1389 inflight 302 sec Therefore, to solve this issue, we free XDP frames via xdp_return_frame() while cleaning the tx BD ring.

2023-07-11net: fec: dynamically set the NETDEV_XDP_ACT_NDO_XMIT feature of XDPWei Fang
When a XDP program is installed or uninstalled, fec_restart() will be invoked to reset MAC and buffer descriptor rings. It's reasonable not to transmit any packet during the process of reset. However, the NETDEV_XDP_ACT_NDO_XMIT bit of xdp_features is enabled by default, that is to say, it's possible that the fec_enet_xdp_xmit() will be invoked even if the process of reset is not finished. In this case, the redirected XDP frames might be dropped and available transmit BDs may be incorrectly deemed insufficient. So this patch disable the NETDEV_XDP_ACT_NDO_XMIT feature by default and dynamically configure this feature when the bpf program is installed or uninstalled.
