This reverts commit 81f95076. It causes random failures of firmware loading at resume time (well, random for me, it seems to be more reliable for others) because the firmware disabling is not actually synchronous with any particular resume event, and at least the btusb driver that uses a workqueue to load the firmware at resume seems to occasionally hit the "firmware loading is disabled" logic because the firmware loader hasn't gotten the resume event yet. Some kind of sanity check for not trying to load firmware when it's not possible might be a good thing, but this commit was not it. Greg seems to have silently suffered the same issue, and pointed to the likely culprit, and Gabriel C verified the revert fixed it for him too.

Load instructions using ASI_PNF or other no-fault ASIs should not cause a SIGSEGV or SIGBUS. A garden variety unmapped address follows the TSB miss path, and when no valid mapping is found in the process page tables, the miss handler checks to see if the access was via a no-fault ASI. It then fixes up the target register with a zero, and skips the no-fault load instruction. But different paths are taken for data access exceptions and alignment traps, and these do not respect the no-fault ASI. We add checks in these paths for the no-fault ASI, and fix up the target register and TPC just like in the TSB miss case.

The code now tries to preserve the mappings of the kernel so that master aborts for devices are avoided. Master aborts cause some devices to fail in the kdump kernel, so this code makes the dump more likely to succeed when AMD IOMMU is enabled. - common flush queue implementation for IOVA code users. The code is still optional, but AMD and Intel IOMMU drivers had their own implementation which is now unified. - finish support for iommu-groups. All drivers implement this feature now so that IOMMU core code can rely on it. - finish support for 'struct iommu_device' in iommu drivers. All drivers now use the interface. - new functions in the IOMMU-API for explicit IO/TLB flushing. This will help to reduce the number of IO/TLB flushes when IOMMU drivers support this interface. - support for mt2712 in the Mediatek IOMMU driver - new IOMMU driver for QCOM hardware - system PM support for ARM-SMMU - shutdown method for ARM-SMMU-v3 - some constification patches - various other small improvements and fixes" * tag 'iommu-updates-v4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (87 commits) iommu/vt-d: Don't be too aggressive when clearing one context entry iommu: Introduce Interface for IOMMU TLB Flushing iommu/s390: Constify iommu_ops iommu/vt-d: Avoid calling virt_to_phys() on null pointer iommu/vt-d: IOMMU Page Request needs to check if address is canonical. arm/tegra: Call bus_set_iommu() after iommu_device_register() iommu/exynos: Constify iommu_ops iommu/ipmmu-vmsa: Make ipmmu_gather_ops const iommu/ipmmu-vmsa: Rereserving a free context before setting up a pagetable iommu/amd: Rename a few flush functions iommu/amd: Check if domain is NULL in get_domain() and return -EBUSY iommu/mediatek: Fix a build warning of BIT(32) in ARM iommu/mediatek: Fix a build fail of m4u_type iommu: qcom: annotate PM functions as __maybe_unused iommu/pamu: Fix PAMU boot crash memory: mtk-smi: Degrade SMI init to module_init iommu/mediatek: Enlarge the validate PA range for 4GB mode iommu/mediatek: Disable iommu clock when system suspend iommu/mediatek: Move pgtable allocation into domain_alloc iommu/mediatek: Merge 2 M4U HWs into one iommu domain ...

Differ between illegal XDP action code and just driver unsupported one to provide better feedback when we throw a one-time warning here. Reason is that with 814abfab ("xdp: add bpf_redirect helper function") not all drivers support the new XDP return code yet and thus they will fall into their 'default' case when checking for return codes after program return, which then triggers a bpf_warn_invalid_xdp_action() stating that the return code is illegal, but from XDP perspective it's not. I decided not to place something like a XDP_ACT_MAX define into uapi i) given we don't have this either for all other program types, ii) future action codes could have further encoding there, which would render such define unsuitable and we wouldn't be able to rip it out again, and iii) we rarely add new action codes.

This reverts commit 95b80bf3 ("mdio_bus: Remove unneeded gpiod NULL check"), this commit assumed that GPIOLIB checks for NULL descriptors, so it's safe to drop them, but it is not when CONFIG_GPIOLIB is disabled in the kernel. If we do call gpiod_set_value_cansleep() on a GPIO descriptor we will issue warnings coming from the inline stubs declared in include/linux/gpio/consumer.h.

John Fastabend says: ==================== net: Fixes for XDP/BPF The following fixes, UAPI updates, and small improvement, i. XDP needs to be called inside RCU with preempt disabled. ii. Not strictly a bug fix but we have an attach command in the sockmap UAPI already to avoid having a single kernel released with only the attach and not the detach I'm pushing this into net branch. Its early in the RC cycle so I think this is OK (not ideal but better than supporting a UAPI with a missing detach forever). iii.

The bpf map sockmap supports adding programs via attach commands. This patch adds the detach command to keep the API symmetric and allow users to remove previously added programs. Otherwise the user would have to delete the map and re-add it to get in this state. This also adds a series of additional tests to capture detach operation and also attaching/detaching invalid prog types. API note: socks will run (or not run) programs depending on the state of the map at the time the sock is added. We do not for example walk the map and remove programs from previously attached socks.

do_xdp_generic must be called inside rcu critical section with preempt disabled to ensure BPF programs are valid and per-cpu variables used for redirect operations are consistent. This patch ensures this is true and fixes the splat below. The netif_receive_skb_internal() code path is now broken into two rcu critical sections. I decided it was better to limit the preempt_enable/disable block to just the xdp static key portion and the fallout is more rcu_read_lock/unlock calls. Seems like the best option to me.

We can potentially run into a couple of issues with the XDP bpf_redirect_map() helper. The ri->map in the per CPU storage can become stale in several ways, mostly due to misuse, where we can then trigger a use after free on the map: i) prog A is calling bpf_redirect_map(), returning XDP_REDIRECT and running on a driver not supporting XDP_REDIRECT yet. The ri->map on that CPU becomes stale when the XDP program is unloaded on the driver, and a prog B loaded on a different driver which supports XDP_REDIRECT return code. prog B would have to omit calling to bpf_redirect_map() and just return XDP_REDIRECT, which would then access the freed map in xdp_do_redirect() since not cleared for that CPU. ii) prog A is calling bpf_redirect_map(), returning a code other than XDP_REDIRECT. prog A is then detached, which triggers release of the map. prog B is attached which, similarly as in i), would just return XDP_REDIRECT without having called bpf_redirect_map() and thus be accessing the freed map in xdp_do_redirect() since not cleared for that CPU. iii) prog A is attached to generic XDP, calling the bpf_redirect_map() helper and returning XDP_REDIRECT. xdp_do_generic_redirect() is currently not handling ri->map (will be fixed by Jesper), so it's not being reset. Later loading a e.g. native prog B which would, say, call bpf_xdp_redirect() and then returns XDP_REDIRECT would find in xdp_do_redirect() that a map was set and uses that causing use after free on map access. Fix thus needs to avoid accessing stale ri->map pointers, naive way would be to call a BPF function from drivers that just resets it to NULL for all XDP return codes but XDP_REDIRECT and including XDP_REDIRECT for drivers not supporting it yet (and let ri->map being handled in xdp_do_generic_redirect()). There is a less intrusive way w/o letting drivers call a reset for each BPF run. The verifier knows we're calling into bpf_xdp_redirect_map() helper, so it can do a small insn rewrite transparent to the prog itself in the sense that it fills R4 with a pointer to the own bpf_prog. We have that pointer at verification time anyway and R4 is allowed to be used as per calling convention we scratch R0 to R5 anyway, so they become inaccessible and program cannot read them prior to a write. Then, the helper would store the prog pointer in the current CPUs struct redirect_info. Later in xdp_do_*_redirect() we check whether the redirect_info's prog pointer is the same as passed xdp_prog pointer, and if that's the case then all good, since the prog holds a ref on the map anyway, so it is always valid at that point in time and must have a reference count of at least 1. If in the unlikely case they are not equal, it means we got a stale pointer, so we clear and bail out right there. Also do reset map and the owning prog in bpf_xdp_redirect(), so that bpf_xdp_redirect_map() and bpf_xdp_redirect() won't get mixed up, only the last call should take precedence. A tc bpf_redirect() doesn't use map anywhere yet, so no need to clear it there since never accessed in that layer. Note that in case the prog is released, and thus the map as well we're still under RCU read critical section at that time and have preemption disabled as well. Once we commit with the __dev_map_insert_ctx() from xdp_do_redirect_map() and set the map to ri->map_to_flush, we still wait for a xdp_do_flush_map() to finish in devmap dismantle time once flush_needed bit is set, so that is fine.
