2022-04-13device property: Allow error pointer to be passed to fwnode APIsAndy Shevchenko1-5/+5
Some of the fwnode APIs might return an error pointer instead of NULL or valid fwnode handle. The result of such API call may be considered optional and hence the test for it is usually done in a form of fwnode = fwnode_find_reference(...); if (IS_ERR(fwnode)) ...error handling... Nevertheless the resulting fwnode may have bumped the reference count and hence caller of the above API is obliged to call fwnode_handle_put(). Since fwnode may be not valid either as NULL or error pointer the check has to be performed there. This approach uglifies the code and adds a point of making a mistake, i.e. forgetting about error point case. To prevent this, allow an error pointer to be passed to the fwnode APIs.

2022-04-13vfio/pci: Fix vf_token mechanism when device-specific VF drivers are usedJason Gunthorpe1-0/+2
get_pf_vdev() tries to check if a PF is a VFIO PF by looking at the driver: if (pci_dev_driver(physfn) != pci_dev_driver(vdev->pdev)) { However now that we have multiple VF and PF drivers this is no longer reliable. This means that security tests realted to vf_token can be skipped by mixing and matching different VFIO PCI drivers. Instead of trying to use the driver core to find the PF devices maintain a linked list of all PF vfio_pci_core_device's that we have called pci_enable_sriov() on. When registering a VF just search the list to see if the PF is present and record the match permanently in the struct. PCI core locking prevents a PF from passing pci_disable_sriov() while VF drivers are attached so the VFIO owned PF becomes a static property of the VF. In common cases where vfio does not own the PF the global list remains empty and the VF's pointer is statically NULL. This also fixes a lockdep splat from recursive locking of the vfio_group::device_lock between vfio_device_get_from_name() and vfio_device_get_from_dev(). If the VF and PF share the same group this would deadlock.

2022-04-13efi: Save location of EFI confidential computing areaDov Murik1-0/+10
Confidential computing (coco) hardware such as AMD SEV (Secure Encrypted Virtualization) allows a guest owner to inject secrets into the VMs memory without the host/hypervisor being able to read them. Firmware support for secret injection is available in OVMF, which reserves a memory area for secret injection and includes a pointer to it the in EFI config table entry LINUX_EFI_COCO_SECRET_TABLE_GUID. If EFI exposes such a table entry, uefi_init() will keep a pointer to the EFI config table entry in efi.coco_secret, so it can be used later by the kernel (specifically drivers/virt/coco/efi_secret). It will also appear in the kernel log as "CocoSecret=ADDRESS"; for example: [ 0.000000] efi: EFI v2.70 by EDK II [ 0.000000] efi: CocoSecret=0x7f22e680 SMBIOS=0x7f541000 ACPI=0x7f77e000 ACPI 2.0=0x7f77e014 MEMATTR=0x7ea0c018 The new functionality can be enabled with CONFIG_EFI_COCO_SECRET=y.

2022-04-13PM: sleep: enable dynamic debug support within pm_pr_dbg()David Cohen1-5/+39
Currently pm_pr_dbg() is used to filter kernel pm debug messages based on pm_debug_messages_on flag. The problem is if we enable/disable this flag it will affect all pm_pr_dbg() calls at once, so we can't individually control them. This patch changes pm_pr_dbg() implementation as such: - If pm_debug_messages_on is enabled, print the message. - If pm_debug_messages_on is disabled and CONFIG_DYNAMIC_DEBUG is enabled, only print the messages explicitly enabled on /sys/kernel/debug/dynamic_debug/control. - If pm_debug_messages_on is disabled and CONFIG_DYNAMIC_DEBUG is disabled, don't print the message.

2022-04-13PM: EM: Add artificial EM flagPierre Gondois1-0/+5
The Energy Model (EM) can be used on platforms which are missing real power information. Those platforms would implement .get_cost() which populates needed values for the Energy Aware Scheduler (EAS). The EAS doesn't use 'power' fields from EM, but other frameworks might use them. Thus, to avoid miss-usage of this specific type of EM, introduce a new flags which can be checked by other frameworks.

2022-04-13PM: EM: Add .get_cost() callbackLukasz Luba1-1/+23
The Energy Model (EM) supports devices which report abstract power scale, not only real Watts. The primary goal for EM is to enable the Energy Aware Scheduler (EAS) for a given platform. Some of the platforms might not be able to deliver proper power values. The only information that they might have is the relative efficiency between CPU types. Thus, it makes sense to remove some restrictions in the EM framework and introduce a mechanism which would support those platforms. What is crucial for EAS to operate is the 'cost' field in the EM. The 'cost' is calculated internally in EM framework based on knowledge from 'power' values. The 'cost' values must be strictly increasing. The existing API with its 'power' value size restrictions cannot guarantee that the 'cost' will meet this requirement. Since the platform is missing this detailed information, but has only efficiency details, introduce a new custom callback in the EM framework. The new callback would allow to provide the 'cost' values which reflect efficiency of the CPUs. This would allow to provide EAS information which has different relation than what would be forced by the EM internal formulas calculating 'cost' values. Thanks to this new callback it is possible to create a system view for EAS which has no overlapping performance states across many Performance Domains.

2022-04-13random: make random_get_entropy() return an unsigned longJason A. Donenfeld1-1/+1
Some implementations were returning type `unsigned long`, while others that fell back to get_cycles() were implicitly returning a `cycles_t` or an untyped constant int literal. That makes for weird and confusing code, and basically all code in the kernel already handled it like it was an `unsigned long`. I recently tried to handle it as the largest type it could be, a `cycles_t`, but doing so doesn't really help with much. Instead let's just make random_get_entropy() return an unsigned long all the time. This also matches the commonly used `arch_get_random_long()` function, so now RDRAND and RDTSC return the same sized integer, which means one can fallback to the other more gracefully.

2022-04-13esp: limit skb_page_frag_refill use to a single pageSabrina Dubroca1-2/+0
Commit ebe48d368e97 ("esp: Fix possible buffer overflow in ESP transformation") tried to fix skb_page_frag_refill usage in ESP by capping allocsize to 32k, but that doesn't completely solve the issue, as skb_page_frag_refill may return a single page. If that happens, we will write out of bounds, despite the check introduced in the previous patch. This patch forces COW in cases where we would end up calling skb_page_frag_refill with a size larger than a page (first in esp_output_head with tailen, then in esp_output_tail with skb->data_len).

2022-04-13ALSA: memalloc: Add fallback SG-buffer allocations for x86Takashi Iwai1-0/+5
The recent change for memory allocator replaced the SG-buffer handling helper for x86 with the standard non-contiguous page handler. This works for most cases, but there is a corner case I obviously overlooked, namely, the fallback of non-contiguous handler without IOMMU. When the system runs without IOMMU, the core handler tries to use the continuous pages with a single SGL entry. It works nicely for most cases, but when the system memory gets fragmented, the large allocation may fail frequently. Ideally the non-contig handler could deal with the proper SG pages, it's cumbersome to extend for now. As a workaround, here we add new types for (minimalistic) SG allocations, instead, so that the allocator falls back to those types automatically when the allocation with the standard API failed. BTW, one better (but pretty minor) improvement from the previous SG-buffer code is that this provides the proper mmap support without the PCM's page fault handling.

2022-04-12asm-generic: fix __get_unaligned_be48() on 32 bit platformsAlexander Lobakin1-1/+1
While testing the new macros for working with 48 bit containers, I faced a weird problem: 32 + 16: 0x2ef6e8da 0x79e60000 48: 0xffffe8da + 0x79e60000 All the bits starting from the 32nd were getting 1d in 9/10 cases. The debug showed: p[0]: 0x00002e0000000000 p[1]: 0x00002ef600000000 p[2]: 0xffffffffe8000000 p[3]: 0xffffffffe8da0000 p[4]: 0xffffffffe8da7900 p[5]: 0xffffffffe8da79e6 that the value becomes a garbage after the third OR, i.e. on `p[2] << 24`. When the 31st bit is 1 and there's no explicit cast to an unsigned, it's being considered as a signed int and getting sign-extended on OR, so `e8000000` becomes `ffffffffe8000000` and messes up the result. Cast the @p[2] to u64 as well to avoid this. Now: 32 + 16: 0x7ef6a490 0xddc10000 48: 0x7ef6a490 + 0xddc10000 p[0]: 0x00007e0000000000 p[1]: 0x00007ef600000000 p[2]: 0x00007ef6a4000000 p[3]: 0x00007ef6a4900000 p[4]: 0x00007ef6a490dd00 p[5]: 0x00007ef6a490ddc1 Fixes: c2ea5fcf53d5 ("asm-generic: introduce be48 unaligned accessors") Signed-off-by: Alexander Lobakin <alobakin@pm.me> Link: https://lore.kernel.org/r/20220412215220.75677-1-alobakin@pm.me Signed-off-by: Jens Axboe <axboe@kernel.dk>

2022-04-12net: remove noblock parameter from recvmsg() entitiesOliver Hartkopp6-10/+9
The internal recvmsg() functions have two parameters 'flags' and 'noblock' that were merged inside skb_recv_datagram(). As a follow up patch to commit f4b41f062c42 ("net: remove noblock parameter from skb_recv_datagram()") this patch removes the separate 'noblock' parameter for recvmsg(). Analogue to the referenced patch for skb_recv_datagram() the 'flags' and 'noblock' parameters are unnecessarily split up with e.g. err = sk->sk_prot->recvmsg(sk, msg, size, flags & MSG_DONTWAIT, flags & ~MSG_DONTWAIT, &addr_len); or in err = INDIRECT_CALL_2(sk->sk_prot->recvmsg, tcp_recvmsg, udp_recvmsg, sk, msg, size, flags & MSG_DONTWAIT, flags & ~MSG_DONTWAIT, &addr_len); instead of simply using only flags all the time and check for MSG_DONTWAIT where needed (to preserve for the formerly separated no(n)block condition).
