The UDP reuseport conflict was a little bit tricky. The net-next code, via bpf-next, extracted the reuseport handling into a helper so that the BPF sk lookup code could invoke it. At the same time, the logic for reuseport handling of unconnected sockets changed via commit efc6b6f6c3113e8b203b9debfb72d81e0f3dcace which changed the logic to carry on the reuseport result into the rest of the lookup loop if we do not return immediately. This requires moving the reuseport_has_conns() logic into the callers. While we are here, get rid of inline directives as they do not belong in foo.c files. The other changes were cases of more straightforward overlapping modifications. Signed-off-by: David S. Miller <davem@davemloft.net>

2020-07-24arm64/vdso: Add time namespace pageAndrei Vagin6-5/+46
Allocate the time namespace page among VVAR pages. Provide __arch_get_timens_vdso_data() helper for VDSO code to get the code-relative position of VVARs on that special page. If a task belongs to a time namespace then the VVAR page which contains the system wide VDSO data is replaced with a namespace specific page which has the same layout as the VVAR page. That page has vdso_data->seq set to 1 to enforce the slow path and vdso_data->clock_mode set to VCLOCK_TIMENS to enforce the time namespace handling path. The extra check in the case that vdso_data->seq is odd, e.g. a concurrent update of the VDSO data is in progress, is not really affecting regular tasks which are not part of a time namespace as the task is spin waiting for the update to finish and vdso_data->seq to become even again. If a time namespace task hits that code path, it invokes the corresponding time getter function which retrieves the real VVAR page, reads host time and then adds the offset for the requested clock which is stored in the special VVAR page. The time-namespace page isn't allocated on !CONFIG_TIME_NAMESPACE, but vma is the same size, which simplifies criu/vdso migration between different kernel configs.

2020-07-24arm64/vdso: Zap vvar pages when switching to a time namespaceAndrei Vagin1-0/+31
The order of vvar pages depends on whether a task belongs to the root time namespace or not. In the root time namespace, a task doesn't have a per-namespace page. In a non-root namespace, the VVAR page which contains the system-wide VDSO data is replaced with a namespace specific page that contains clock offsets. Whenever a task changes its namespace, the VVAR page tables are cleared and then they will be re-faulted with a corresponding layout. A task can switch its time namespace only if its ->mm isn't shared with another task.

Currently the vdso has no awareness of time namespaces, which may apply distinct offsets to processes in different namespaces. To handle this within the vdso, we'll need to expose a per-namespace data page. As a preparatory step, this patch separates the vdso data page from the code pages, and has it faulted in via its own fault callback. Subsquent patches will extend this to support distinct pages per time namespace. The vvar vma has to be installed with the VM_PFNMAP flag to handle faults via its vma fault callback.

Biggest part is the addition of the rk3288 variant of the VMARC SOM and it's Rock Pi N8 icarnation. This brings some arm64 dts-changes with it as the underlying Dalang carrier board is shared by both an arm32 rk3288 SOM and an arm64 rk3399 SOM (Rock Pi N10).

Qualcomm ARM64 DT updates for v5.9 For SM8250 this adds the main pinctrl/gpio block (TLMM), I2C and SPI controllers, the CPU subsytem watchdog, inter-processor signalling controller (IPCC), always-on power/clock controller (AOSS), inter-processor state machine (SMP2P), defines remoteproc controls for audio, compute and sensor processors and base definition for the PM8009 PMIC. It also does fix up a few minor issues from the initial merge of the platform support. SC7180 and SDM845 gains interconnect paths and performance tables defined for display, QUP, QSPI, SDHC and CPUs. SC7180 gains WiFi support and some cleanups related to the modem remoteproc. SDM845 gains inline crypto engine support for UFS, LAB/IBB regulators for powering display panels, remoteproc relocation debug support SM8150 gains USB controller support and the two related PHYs, as well as thermal zones and throttling support. IPQ8074 gains USB and SDHCI support. MSM8916 is being cleaned up, gains interconnect providers and Samsung A2015 gains accelerometer and magnetometer support. MSM8994 gains PSCI, SDHCI, SPMI support, I2C, SPI, UART gains DMA support and the DTS files are cleaned up. The SDM630 platform DTS is at last merged and initial support for Sony Xperia 10, 10 Plus, XA2, XA2 Plus and XA2 Ultra is added. * tag 'qcom-arm64-for-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (66 commits) arm64: dts: qcom: pmi8998: Add nodes for LAB and IBB regulators arm64: dts: sc7180: Add DSI and MDP OPP tables and power-domains arm64: dts: sdm845: Add DSI and MDP OPP tables and power-domains arm64: dts: qcom: sc7180: Move the fixed-perm property to SoC dtsi arm64: dts: qcom: msm8916-samsung-a2015: Add accelerometer/magnetometer arm64: dts: qcom: msm8916: Use higher I2C drive-strength only on DB410c arm64: dts: qcom: msm8916: Simplify pinctrl configuration arm64: dts: msm8916-samsung/longcheer: Move pinctrl/regulators to end of file arm64: dts: qcom: sm8250: Drop tcsr_mutex syscon arm64: dts: qcom: sc7180: Add missing properties for Wifi node arm64: dts: qcom: Fix WiFi supplies on sc7180-idp arm64: dts: sdm845: add Inline Crypto Engine registers and clock arm64: dts: sc7180: Add sdhc opps and power-domains arm64: dts: sdm845: Add sdhc opps and power-domains arm64: dts: sc7180: Add OPP table for all qup devices arm64: dts: sdm845: Add OPP table for all qup devices arm64: dts: sc7180: Add qspi opps and power-domains arm64: dts: sdm845: Add qspi opps and power-domains arm64: dts: qcom: sdm845: Add cpu OPP tables arm64: dts: qcom: sc7180: Drop the unused non-MSA SID ...
