2021-05-14arm64: dts: ti: k3*: Introduce reg definition for interrupt routersNishanth Menon
Interrupt routers are memory mapped peripherals, that are organized in our dts bus hierarchy to closely represents the actual hardware behavior. However, without explicitly calling out the reg property, using 2021.03+ dt-schema package, this exposes the following problem with dtbs_check: /arch/arm64/boot/dts/ti/k3-am654-base-board.dt.yaml: bus@100000: interrupt-controller0: {'type': 'object'} is not allowed for {'compatible': ['ti,sci-intr'], ..... Even though we don't use interrupt router directly via memory mapped registers and have to use it via the system controller, the hardware block is memory mapped, so describe the base address in device tree. This is a valid, comprehensive description of hardware and permitted by the existing ti,sci-intr schema.

Pointers to ring-buffer packets sent by Hyper-V are used within the guest VM. Hyper-V can send packets with erroneous values or modify packet fields after they are processed by the guest. To defend against these scenarios, return a copy of the incoming VMBus packet after validating its length and offset fields in hv_pkt_iter_first(). In this way, the packet can no longer be modified by the host.

2021-05-14arm64: Fix race condition on PG_dcache_clean in __sync_icache_dcache()Catalin Marinas
To ensure that instructions are observable in a new mapping, the arm64 set_pte_at() implementation cleans the D-cache and invalidates the I-cache to the PoU. As an optimisation, this is only done on executable mappings and the PG_dcache_clean page flag is set to avoid future cache maintenance on the same page. When two different processes map the same page (e.g. private executable file or shared mapping) there's a potential race on checking and setting PG_dcache_clean via set_pte_at() -> __sync_icache_dcache(). While on the fault paths the page is locked (PG_locked), mprotect() does not take the page lock. The result is that one process may see the PG_dcache_clean flag set but the I/D cache maintenance not yet performed. Avoid test_and_set_bit(PG_dcache_clean) in favour of separate test_bit() and set_bit(). In the rare event of a race, the cache maintenance is done twice.

2021-05-14uio_hv_generic: Fix another memory leak in error handling pathsChristophe JAILLET
Memory allocated by 'vmbus_alloc_ring()' at the beginning of the probe function is never freed in the error handling path. Add the missing 'vmbus_free_ring()' call. Note that it is already freed in the .remove function.

2021-05-14uio_hv_generic: Fix a memory leak in error handling pathsChristophe JAILLET
If 'vmbus_establish_gpadl()' fails, the (recv|send)_gpadl will not be updated and 'hv_uio_cleanup()' in the error handling path will not be able to free the corresponding buffer. In such a case, we need to free the buffer explicitly.

2021-05-14uio/uio_pci_generic: fix return value changed in refactoringMartin Ågren
Commit ef84928cff58 ("uio/uio_pci_generic: use device-managed function equivalents") was able to simplify various error paths thanks to no longer having to clean up on the way out. Some error paths were dropped, others were simplified. In one of those simplifications, the return value was accidentally changed from -ENODEV to -ENOMEM. Restore the old return value.

2021-05-14crypto: ixp4xx - fallback when having more than one SGCorentin Labbe
Testing ixp4xx_crypto lead to: alg: skcipher: ecb(des)-ixp4xx encryption overran dst buffer on test vector 0, cfg="two even aligned splits" The HW overwrites destination always when sg_nents() > 1. The problem seems that the HW always write areq->cryptlen bytes on the last SG. A comment in driver's code seems to give a clue that multiple SG was not planned "This was never tested by Intel for more than one dst buffer, I think". So let's add a fallback for this situation.
