2022-01-09netfilter: conntrack: avoid useless indirection during conntrack destructionFlorian Westphal
nf_ct_put() results in a usesless indirection: nf_ct_put -> nf_conntrack_put -> nf_conntrack_destroy -> rcu readlock + indirect call of ct_hooks->destroy(). There are two _put helpers: nf_ct_put and nf_conntrack_put. The latter is what should be used in code that MUST NOT cause a linker dependency on the conntrack module (e.g. calls from core network stack). Everyone else should call nf_ct_put() instead. A followup patch will convert a few nf_conntrack_put() calls to nf_ct_put(), in particular from modules that already have a conntrack dependency such as act_ct or even nf_conntrack itself.

2022-01-09netfilter: conntrack: convert to refcount_t apiFlorian Westphal
Convert nf_conn reference counting from atomic_t to refcount_t based api. refcount_t api provides more runtime sanity checks and will warn on certain constructs, e.g. refcount_inc() on a zero reference count, which usually indicates use-after-free. For this reason template allocation is changed to init the refcount to 1, the subsequenct add operations are removed. Likewise, init_conntrack() is changed to set the initial refcount to 1 instead refcount_inc(). This is safe because the new entry is not (yet) visible to other cpus.

2022-01-09riscv: try to allocate crashkern region from 32bit addressible memoryNick Kossifidis
When allocating crash kernel region without explicitly specifying its base address/size, memblock_phys_alloc_range will attempt to allocate memory top to bottom (memblock.bottom_up is false), so the crash kernel region will end up in highmem on 64bit systems. This way swiotlb can't work on the crash kernel, since there won't be any 32bit addressible memory available for the bounce buffers. Try to allocate 32bit addressible memory if available, for the crash kernel by restricting the top search address to be less than SZ_4G. If that fails fallback to the previous behavior. I tested this on HiFive Unmatched where the pci-e controller needs swiotlb to work, with this patch it's possible to access the pci-e controller on crash kernel and mount the rootfs from the nvme.

This fixes kexec on HiFive Unleashed/Unmatched where cpu ids and hart ids don't match (on qemu-virt they match).

2022-01-09riscv: Don't use va_pa_offset on kdumpNick Kossifidis
On kdump instead of using an intermediate step to relocate the kernel, that lives in a "control buffer" outside the current kernel's mapping, we jump to the crash kernel directly by calling riscv_kexec_norelocate(). The current implementation uses va_pa_offset while switching to physical addressing, however since we moved the kernel outside the linear mapping this won't work anymore since riscv_kexec_norelocate() is part of the kernel mapping and we should use kernel_map.va_kernel_pa_offset, and also take XIP kernel into account. We don't really need to use va_pa_offset on riscv_kexec_norelocate, we can just set STVEC to the physical address of the new kernel instead and let the hart jump to the new kernel on the next instruction after setting SATP to zero. This fixes kdump and is also simpler/cleaner. I tested this on the latest qemu and HiFive Unmatched and works as expected.

An ethtool private flag is added to optionally disable CAN RTR frame reception, to make use of more RX buffers. The resulting RX buffer configuration can be read by ethtool ring parameter support.

2022-01-09can: xilinx_can: xcan_probe(): check for error irqJiasheng Jiang
For the possible failure of the platform_get_irq(), the returned irq could be error number and will finally cause the failure of the request_irq(). Consider that platform_get_irq() can now in certain cases return -EPROBE_DEFER, and the consequences of letting request_irq() effectively convert that into -EINVAL, even at probe time rather than later on. So it might be better to check just now.

2022-01-08Input: zinitix - handle proper supply namesLinus Walleij
The supply names of the Zinitix touchscreen were a bit confused, the new bindings rectifies this. To deal with old and new devicetrees, first check if we have "vddo" and in case that exists assume the old supply names. Else go and look for the new ones. We cannot just get the regulators since we would get an OK and a dummy regulator: we need to check explicitly for the old supply name. Use struct device *dev as a local variable instead of the I2C client since the device is what we are actually obtaining the resources from.
