2021-10-05ARM: imx6: disable the GIC CPU interface before calling stby-poweroff sequenceOleksij Rempel1-0/+2
Any pending interrupt can prevent entering standby based power off state. To avoid it, disable the GIC CPU interface.

2021-10-05ALSA: usb-audio: Enable rate validation for Scarlett devicesTakashi Iwai1-0/+2
The Scarlett device series from Focusrite Novation seem requiring the sample rate validations as we've done for MOTU devices; otherwise the driver probes invalid audioformat entries that contain the sample rates that actually don't work, and this may result in an incomplete setup as reported recently. This patch adds the needed quirk flag for enabling the sample rate validation for Focusrite Novation devices.

2021-10-04scsi: iscsi: Fix iscsi_task use after freeMike Christie1-6/+9
Commit d39df158518c ("scsi: iscsi: Have abort handler get ref to conn") added iscsi_get_conn()/iscsi_put_conn() calls during abort handling but then also changed the handling of the case where we detect an already completed task where we now end up doing a goto to the common put/cleanup code. This results in a iscsi_task use after free, because the common cleanup code will do a put on the iscsi_task. This reverts the goto and moves the iscsi_get_conn() to after we've checked if the iscsi_task is valid.

2021-10-04scsi: lpfc: Fix memory overwrite during FC-GS I/O abort handlingJames Smart1-4/+7
When an FC-GS I/O is aborted by lpfc, the driver requires a node pointer for a dereference operation. In the abort I/O routine, the driver miscasts a context pointer to the wrong data type and overwrites a single byte outside of the allocated space. This miscast is done in the abort I/O function handler because the handler works on both FC-GS and FC-LS commands. However, the code neglected to get the correct job location for the node. Fix this by acquiring the necessary node pointer from the correct job structure depending on the I/O type.

2021-10-04scsi: ufs: core: Fix task management completionAdrian Hunter2-30/+23
The UFS driver uses blk_mq_tagset_busy_iter() when identifying task management requests to complete, however blk_mq_tagset_busy_iter() doesn't work. blk_mq_tagset_busy_iter() only iterates requests dispatched by the block layer. That appears as if it might have started since commit 37f4a24c2469 ("blk-mq: centralise related handling into blk_mq_get_driver_tag") which removed 'data->hctx->tags->rqs[rq->tag] = rq' from blk_mq_rq_ctx_init() which gets called: blk_get_request blk_mq_alloc_request __blk_mq_alloc_request blk_mq_rq_ctx_init Since UFS task management requests are not dispatched by the block layer, hctx->tags->rqs[rq->tag] remains NULL, and since blk_mq_tagset_busy_iter() relies on finding requests using hctx->tags->rqs[rq->tag], UFS task management requests are never found by blk_mq_tagset_busy_iter(). By using blk_mq_tagset_busy_iter(), the UFS driver was relying on internal details of the block layer, which was fragile and subsequently got broken. Fix by removing the use of blk_mq_tagset_busy_iter() and having the driver keep track of task management requests.

Looking at the backtrace, the illegal instruction is encountered in this same function. However, patch_text_nosync, after patching the instructions, calls flush_icache_range. But looking at what happens in this function: flush_icache_range -> flush_icache_all -> sbi_remote_fence_i -> __sbi_rfence_v02 -> riscv_cpuid_to_hartid_mask The icache and dcache of the current cpu are never synchronized between the patching of riscv_cpuid_to_hartid_mask and calling this same function.

With commit c709135e576b ("pinctrl: at91-pio4: add support for slew-rate") and commit cbde6c823bfa ("pinctrl: at91-pio4: Fix slew rate disablement") the slew-rate is enabled by default for each configured pin. The datasheet specifies at chapter "Output Driver AC Characteristics" that HSIO drivers (use in SDMMCx and QSPI0 peripherals), don't have a slewrate setting but are rather calibrated against an external 1% resistor mounted on the SDMMCx_CAL or QSPI0_CAL pins. Depending on the target signal frequency and the external load, it is possible to adjust their target output impedance. Thus set slew-rate = <0> for SDMMC (QSPI is not enabled at the moment in device tree).

2021-10-04ARM: at91: pm: preload base address of controllers in tlbClaudiu Beznea1-1/+24
In suspend/resume procedure for AT91 architecture different controllers (PMC, SHDWC, RAM, RAM PHY, SFRBU) are accessed to do the proper settings for power saving. Commit f0bbf17958e8 ("ARM: at91: pm: add self-refresh support for sama7g5") introduced the access to RAMC PHY controller for SAMA7G5. The access to this controller is done after RAMC ports are closed, thus any TLB walk necessary for RAMC PHY virtual address will fail. In the development branch this was not encountered. However, on current kernel the issue is reproducible. To solve the issue the previous mechanism of pre-loading the TLB with the RAMC PHY virtual address has been used. However, only the addition of this new pre-load breaks the functionality for ARMv5 based devices (SAM9X60). This behavior has been encountered previously while debugging this code and using the same mechanism for pre-loading address for different controllers (e.g. pin controller, the assumption being that other requested translations are replaced from TLB). To solve this new issue the TLB flush + the extension of pre-loading the rest of controllers to TLB (e.g. PMC, RAMC) has been added. The rest of the controllers should have been pre-loaded previously, anyway.

2021-10-04ARM: dts: at91: sama7g5ek: add suspend voltage for ddr3l railClaudiu Beznea1-0/+2
SAMA7G5-EK board has DDR3L type of memory soldered. This needs 1.35V. The 1.35V for DDR3L rail at run-time is selected by the proper configuration on SELV2 pin (for 1.35V it needs to be in high-z state). When suspended the MCP16502 PMIC soldered on SAMA7G5-EK will use different sets of configuration registers to provide proper voltages on its rail. Run-time configuration registers could be configured differently than suspend configuration register for MCP16502 (VSEL2 affects only run-time configuration). In suspend states the DDR3L memory soldered on SAMA7G5-EK switches to self-refresh. Even on self-refresh it needs to be powered by a 1.35V rail. Thus, make sure the PMIC is configured properly when system is suspended.

2021-10-04s390/pci: fix zpci_zdev_put() on reserveNiklas Schnelle4-15/+45
Since commit 2a671f77ee49 ("s390/pci: fix use after free of zpci_dev") the reference count of a zpci_dev is incremented between pcibios_add_device() and pcibios_release_device() which was supposed to prevent the zpci_dev from being freed while the common PCI code has access to it. It was missed however that the handling of zPCI availability events assumed that once zpci_zdev_put() was called no later availability event would still see the device. With the previously mentioned commit however this assumption no longer holds and we must make sure that we only drop the initial long-lived reference the zPCI subsystem holds exactly once. Do so by introducing a zpci_device_reserved() function that handles when a device is reserved. Here we make sure the zpci_dev will not be considered for further events by removing it from the zpci_list. This also means that the device actually stays in the ZPCI_FN_STATE_RESERVED state between the time we know it has been reserved and the final reference going away. We thus need to consider it a real state instead of just a conceptual state after the removal. The final cleanup of PCI resources, removal from zbus, and destruction of the IOMMU stays in zpci_release_device() to make sure holders of the reference do see valid data until the release.

In commit b212921b13bd ("elf: don't use MAP_FIXED_NOREPLACE for elf executable mappings") we still leave MAP_FIXED_NOREPLACE in place for load_elf_interp. Unfortunately, this will cause kernel to fail to start with: 1 (init): Uhuuh, elf segment at 00003ffff7ffd000 requested but the memory is mapped already Failed to execute /init (error -17) The reason is that the elf interpreter (ld.so) has overlapping segments. readelf -l ld-2.31.so Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flags Align LOAD 0x0000000000000000 0x0000000000000000 0x0000000000000000 0x000000000002c94c 0x000000000002c94c R E 0x10000 LOAD 0x000000000002dae0 0x000000000003dae0 0x000000000003dae0 0x00000000000021e8 0x0000000000002320 RW 0x10000 LOAD 0x000000000002fe00 0x000000000003fe00 0x000000000003fe00 0x00000000000011ac 0x0000000000001328 RW 0x10000 The reason for this problem is the same as described in commit ad55eac74f20 ("elf: enforce MAP_FIXED on overlaying elf segments").

2021-10-03objtool: print out the symbol type when complaining about itLinus Torvalds1-4/+8
The objtool warning that the kvm instruction emulation code triggered wasn't very useful: arch/x86/kvm/emulate.o: warning: objtool: __ex_table+0x4: don't know how to handle reloc symbol type: kvm_fastop_exception in that it helpfully tells you which symbol name it had trouble figuring out the relocation for, but it doesn't actually say what the unknown symbol type was that triggered it all. In this case it was because of missing type information (type 0, aka STT_NOTYPE), but on the whole it really should just have printed that out as part of the message. Because if this warning triggers, that's very much the first thing you want to know - why did reloc2sec_off() return failure for that symbol? So rather than just saying you can't handle some type of symbol without saying what the type _was_, just print out the type number too.

2021-10-03kvm: fix objtool relocation warningLinus Torvalds1-1/+0
The recent change to make objtool aware of more symbol relocation types (commit 24ff65257375: "objtool: Teach get_alt_entry() about more relocation types") also added another check, and resulted in this objtool warning when building kvm on x86: arch/x86/kvm/emulate.o: warning: objtool: __ex_table+0x4: don't know how to handle reloc symbol type: kvm_fastop_exception The reason seems to be that kvm_fastop_exception() is marked as a global symbol, which causes the relocation to ke kept around for objtool. And at the same time, the kvm_fastop_exception definition (which is done as an inline asm statement) doesn't actually set the type of the global, which then makes objtool unhappy. The minimal fix is to just not mark kvm_fastop_exception as being a global symbol. It's only used in that one compilation unit anyway, so it was always pointless. That's how all the other local exception table labels are done. I'm not entirely happy about the kinds of games that the kvm code plays with doing its own exception handling, and the fact that it confused objtool is most definitely a symptom of the code being a bit too subtle and ad-hoc. But at least this trivial one-liner makes objtool no longer upset about what is going on.
