2024-12-03ice: Fix NULL pointer dereference in switchdevWojciech Drewek
Commit 608a5c05c39b ("virtchnl: support queue rate limit and quanta size configuration") introduced new virtchnl ops: - get_qos_caps - cfg_q_bw - cfg_q_quanta New ops were added to ice_virtchnl_dflt_ops, in commit 015307754a19 ("ice: Support VF queue rate limit and quanta size configuration"), but not to the ice_virtchnl_repr_ops. Because of that, if we get one of those messages in switchdev mode we end up with NULL pointer dereference: [ 1199.794701] BUG: kernel NULL pointer dereference, address: 0000000000000000 [ 1199.794804] Workqueue: ice ice_service_task [ice] [ 1199.794878] RIP: 0010:0x0 [ 1199.795027] Call Trace: [ 1199.795033] <TASK> [ 1199.795039] ? __die+0x20/0x70 [ 1199.795051] ? page_fault_oops+0x140/0x520 [ 1199.795064] ? exc_page_fault+0x7e/0x270 [ 1199.795074] ? asm_exc_page_fault+0x22/0x30 [ 1199.795086] ice_vc_process_vf_msg+0x6e5/0xd30 [ice] [ 1199.795165] __ice_clean_ctrlq+0x734/0x9d0 [ice] [ 1199.795207] ice_service_task+0xccf/0x12b0 [ice] [ 1199.795248] process_one_work+0x21a/0x620 [ 1199.795260] worker_thread+0x18d/0x330 [ 1199.795269] ? __pfx_worker_thread+0x10/0x10 [ 1199.795279] kthread+0xec/0x120 [ 1199.795288] ? __pfx_kthread+0x10/0x10 [ 1199.795296] ret_from_fork+0x2d/0x50 [ 1199.795305] ? __pfx_kthread+0x10/0x10 [ 1199.795312] ret_from_fork_asm+0x1a/0x30 [ 1199.795323] </TASK> Fixes: 015307754a19 ("ice: Support VF queue rate limit and quanta size configuration") Reviewed-by: Przemek Kitszel <przemyslaw.kitszel@intel.com> Reviewed-by: Michal Swiatkowski <michal.swiatkowski@linux.intel.com> Signed-off-by: Wojciech Drewek <wojciech.drewek@intel.com> Reviewed-by: Simon Horman <horms@kernel.org> Tested-by: Sujai Buvaneswaran <sujai.buvaneswaran@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>

2024-12-03ice: fix PHY Clock Recovery availability checkArkadiusz Kubalewski
To check if PHY Clock Recovery mechanic is available for a device, there is a need to verify if given PHY is available within the netlist, but the netlist node type used for the search is wrong, also the search context shall be specified. Modify the search function to allow specifying the context in the search. Use the PHY node type instead of CLOCK CONTROLLER type, also use proper search context which for PHY search is PORT, as defined in E810 Datasheet [1] ('3.3.8.2.4 Node Part Number and Node Options (0x0003)' and 'Table 3-105.

2024-12-03MAINTAINERS: Add CCA and pKVM CoCO guest support to the ARM64 entryWill Deacon
Commits 7999edc484ca ("virt: arm-cca-guest: TSM_REPORT support for realm") and a06c3fad49a5 ("drivers/virt: pkvm: Add initial support for running as a protected guest") added arm64 guest-side support for running in CCA and pKVM confidential computing environments respectively. Unfortunately, these changes were not accompanied by a MAINTAINERS entry and so aren't automatically picked up by the get_maintainer.pl script. Since the initial support was merged via the arm64 tree, extend the ARM64 entry to cover the two new directories.

Calling the MMIO_GUARD hypercall from guests which have not been enrolled (e.g. because they are running without pvmfw) results in -EINVAL being returned. In this case, MMIO_GUARD is not active and so we can simply proceed with the normal ioremap() routine. Don't fail ioremap() if MMIO_GUARD fails; instead WARN_ON_ONCE() to highlight that the pvm environment is slightly wonky.

2024-12-03perf machine: Initialize machine->env to address a segfaultArnaldo Carvalho de Melo
Its used from trace__run(), for the 'perf trace' live mode, i.e. its strace-like, non-perf.data file processing mode, the most common one. The trace__run() function will set trace->host using machine__new_host() that is supposed to give a machine instance representing the running machine, and since we'll use perf_env__arch_strerrno() to get the right errno -> string table, we need to use machine->env, so initialize it in machine__new_host().

Before that commit, the arithmetic performed by page_to_phys() would give the expected physical address, though it is somewhat dubious to use vmemmap addresses before the vmemmap has been initialized. Aside from kernel image addresses, all executable code should be allocated from execmem (where all allocations will fall within the vmalloc area), and so there's no need for the fallback case when CONFIG_EXECMEM=n. Simplify patch_map() accordingly, directly converting kernel image addresses and removing the redundant fallback case.

2024-12-03of: Fix error path in of_parse_phandle_with_args_map()Herve Codina
The current code uses some 'goto put;' to cancel the parsing operation and can lead to a return code value of 0 even on error cases. Indeed, some goto calls are done from a loop without setting the ret value explicitly before the goto call and so the ret value can be set to 0 due to operation done in previous loop iteration. For instance match can be set to 0 in the previous loop iteration (leading to a new iteration) but ret can also be set to 0 it the of_property_read_u32() call succeed. In that case if no match are found or if an error is detected the new iteration, the return value can be wrongly 0. Avoid those cases setting the ret value explicitly before the goto calls.

2024-12-03arm64: mm: Fix zone_dma_limit calculationYang Shi
Commit ba0fb44aed47 ("dma-mapping: replace zone_dma_bits by zone_dma_limit") and subsequent patches changed how zone_dma_limit is calculated to allow a reduced ZONE_DMA even when RAM starts above 4GB. Commit 122c234ef4e1 ("arm64: mm: keep low RAM dma zone") further fixed this to ensure ZONE_DMA remains below U32_MAX if RAM starts below 4GB, especially on platforms that do not have IORT or DT description of the device DMA ranges. While zone boundaries calculation was fixed by the latter commit, zone_dma_limit, used to determine the GFP_DMA flag in the core code, was not updated. This results in excessive use of GFP_DMA and unnecessary ZONE_DMA allocations on some platforms. Update zone_dma_limit to match the actual upper bound of ZONE_DMA.

2024-12-03firmware: arm_scmi: Fix i.MX build dependencyArnd Bergmann
The newly added SCMI vendor driver references functions in the protocol driver but needs a Kconfig dependency to ensure it can link, essentially the Kconfig dependency needs to be reversed to match the link time dependency: | arm-linux-gnueabi-ld: sound/soc/fsl/fsl_mqs.o: in function `fsl_mqs_sm_write': | fsl_mqs.c:(.text+0x1aa): undefined reference to `scmi_imx_misc_ctrl_set' | arm-linux-gnueabi-ld: sound/soc/fsl/fsl_mqs.o: in function `fsl_mqs_sm_read': | fsl_mqs.c:(.text+0x1ee): undefined reference to `scmi_imx_misc_ctrl_get' This however only works after changing the dependency in the SND_SOC_FSL_MQS driver as well, which uses 'select IMX_SCMI_MISC_DRV' to turn on a driver it depends on. This is generally a bad idea, so the best solution is to change that into a dependency. To allow the ASoC driver to keep building with the SCMI support, this needs to be an optional dependency that enforces the link-time dependency if IMX_SCMI_MISC_DRV is a loadable module but not depend on it if that is disabled.

a bus Use snd_soc_dai_set_tdm_slot() on capture DAIs to prevent multiple aggregated amps from trying to send data at the same time. When the capture DAIs of multiple amps on a bus are aggregated they will all be sharing the same bit slots for transmitted audio. This would lead to bus errors if all channels on all amps were enabled, because multiple amps would be trying to send data at the same time. To prevent this, the available channels are divided between the amps on a bus so that only one amp will be sending data for each channel position. A CS35L56 has 4 TX channels, which must be split between all the amps on a bus so that no two amps are using the same channel. This is done simply by dividing by the number of amps on the bus, so that 1 amp can use all 4 channels, 2 amps can use 2 channels each, and 3 or 4 amps can only use 1 channel each. The amps are usually aggregated across multiple SoundWire buses. In this case there will be multiple cpu DAIs in the dailink. The channel mapping is used to determine which amps are on each bus. The allocation of the 4 channels is done separately for each bus (only amps on the same bus can interfere with each other).

2024-12-03ASoC: cs35l56: Split SoundWire DAI into separate playback and captureRichard Fitzgerald
This patch splits the SoundWire capture DP into a separate DAI so that it can be independently routed and/or aggregated. It also makes corresponding changes to the SOF SoundWire machine driver. The playback and capture over SoundWire are separate DPs so don't have to route to the same place. They could also be aggregated differently - for example the playback DP could be aggregated with a playback-only DAI on a codec. No production device currently uses the capture path and their topologies do not connect it. So there is no need to change the machine driver match table entries for these. They will simply drop the unused capture DAI. There is one hookup used for a non-production development board that was added by commit 05fe62842804 ("ASoC: Intel: soc-acpi-intel-mtl-match: add acpi match table for cdb35l56-eight-c") This is the only hookup using a topology that connects the SoundWire DP for capture, so this hookup has been changed to include an aggregated endpoint for the capture DAI.

This looks safer, however, it leads to a classic Time-of-Check to Time-of-Use (TOCTOU) bug since IFLA_NET_NS_PID is very dynamic. And because of the lack of checking error pointer of the second call, it also leads to a kernel crash as reported by syzbot. Fix this by getting rid of the second call, which already becomes redudant after Kuniyuki's work. We have to propagate the result of the first rtnl_link_get_net_ifla() down to each ->newlink().

2024-12-03wifi: mac80211: fix vif addr when switching from monitor to stationFelix Fietkau
Since adding support for opting out of virtual monitor support, a zero vif addr was used to indicate passive vs active monitor to the driver. This would break the vif->addr when changing the netdev mac address before switching the interface from monitor to sta mode. Fix the regression by adding a separate flag to indicate whether vif->addr is valid.

2024-12-03wifi: mac80211: fix a queue stall in certain cases of CSAEmmanuel Grumbach
If we got an unprotected action frame with CSA and then we heard the beacon with the CSA IE, we'll block the queues with the CSA reason twice. Since this reason is refcounted, we won't wake up the queues since we wake them up only once and the ref count will never reach 0. This led to blocked queues that prevented any activity (even disconnection wouldn't reset the queue state and the only way to recover would be to reload the kernel module. Fix this by not refcounting the CSA reason. It becomes now pointless to maintain the csa_blocked_queues state. Remove it.

In case we fail to resume, we'll WARN with "Hardware became unavailable during restart." and we'll wait until user space does something. It'll typically bring the interface down and up to recover. This won't work though because the queues are still stopped on IEEE80211_QUEUE_STOP_REASON_SUSPEND reason. Make sure we clear that reason so that we give a chance to the recovery to succeed.

2024-12-03wifi: cfg80211: clear link ID from bitmap during link delete after clean upAditya Kumar Singh
Currently, during link deletion, the link ID is first removed from the valid_links bitmap before performing any clean-up operations. However, some functions require the link ID to remain in the valid_links bitmap. One such example is cfg80211_cac_event(). The flow is - nl80211_remove_link() cfg80211_remove_link() ieee80211_del_intf_link() ieee80211_vif_set_links() ieee80211_vif_update_links() ieee80211_link_stop() cfg80211_cac_event() cfg80211_cac_event() requires link ID to be present but it is cleared already in cfg80211_remove_link(). Ultimately, WARN_ON() is hit. Therefore, clear the link ID from the bitmap only after completing the link clean-up.

2024-12-03wifi: mac80211: fix mbss changed flags corruption on 32 bit systemsIssam Hamdi
On 32-bit systems, the size of an unsigned long is 4 bytes, while a u64 is 8 bytes. Therefore, when using or_each_set_bit(bit, &bits, sizeof(changed) * BITS_PER_BYTE), the code is incorrectly searching for a bit in a 32-bit variable that is expected to be 64 bits in size, leading to incorrect bit finding. Solution: Ensure that the size of the bits variable is correctly adjusted for each architecture.

2024-12-03ARM: imx: Re-introduce the PINCTRL selectionFabio Estevam
Since commit 17d210018914 ("ARM: imx: Allow user to disable pinctrl"), the CONFIG_PINCTRL option is no longer implicitly selected, causing several i.MX SoC pinctrl drivers no longer getting selected by default. This causes boot regressions on the ARMv4, ARMv5, ARMv6 and ARMv7 i.MX SoCs. Fix it by selecting CONFIG_PINCTRL as before. This defeats the purpose of 7d210018914 ("ARM: imx: Allow user to disable pinctrl"), but it is the less invasive fix for the boot regressions. The attempt to build Layerscape without pinctrl can still be explored later as suggested by Arnd: "Overall, my best advice here is still to not change the way i.MX pinctrl works at all, but just fix Layerscape to not depend on i.MX. The reason for the 'select' here is clearly that the i.MX machines would fail to boot without pinctrl, and changing that because of Layerscape seems backwards."
