2020-10-05rxrpc: The server keyring isn't network-namespacedDavid Howells

2020-10-05rxrpc: Fix accept on a connection that need securingDavid Howells
When a new incoming call arrives at an userspace rxrpc socket on a new connection that has a security class set, the code currently pushes it onto the accept queue to hold a ref on it for the socket. This doesn't work, however, as recvmsg() pops it off, notices that it's in the SERVER_SECURING state and discards the ref. This means that the call runs out of refs too early and the kernel oopses. By contrast, a kernel rxrpc socket manually pre-charges the incoming call pool with calls that already have user call IDs assigned, so they are ref'd by the call tree on the socket. Change the mode of operation for userspace rxrpc server sockets to work like this too. Although this is a UAPI change, server sockets aren't currently functional.

Holland <samuel@sholland.org>: This series adds support the other two AIFs present in the sun8i codec, which can be used for codec2codec DAI links. This series first cleans up the DAPM component driver so there is an organized place to put the new widgets. Then it fills out the DAI driver, removing assumptions that were made for AIF1 (16 bits, 2 channels, certain clock inversions). Some new logic is required to handle 3 DAIs and the ADC/DAC sharing the same clock. Finally, it adds the new DAIs, and hooks them up with DAPM widgets and routes per the hardware topology. To minimize the number of patches in this series, related device tree patches (increasing #sound-dai-cells, adding new DAI links) will be sent separately.

2020-10-05ASoC: sun8i-codec: Set up clock tree at probe timeSamuel Holland
The sun8i codec is effectively an on-die variant of the X-Powers AC100 codec. The AC100 can derive its clocks from either of two I2S master clocks or an internal PLL. For the on-die variant, Allwinner replaced the codec's own PLL with a connection to SoC's existing PLL_AUDIO, and they connected both I2S MCLK inputs to the same source -- which happens to be an integer divider from the same PLL_AUDIO. So there's actually no clocking flexibility. To run SYSCLK at the required rate, it must be run straight from the PLL. The only choice is whether it goes through AIF1CLK or AIF2CLK. Since both run at the same rate, the only effect of that choice is which field in SYS_SR_CTRL (AIF1_FS or AIF2_FS) controls the system sample rate. Since AIFnCLK is required to bring up the corresponding DAI, and AIF1 (connected to the CPU) is used most often, let's use AIF1CLK as the SYSCLK parent. That means we no longer need to set AIF2_FS. Since this clock tree never changes, we can program it from the component probe function, instead of using DAPM widgets. The DAPM widgets unnecessarily change clock parents when the codec goes in/out of idle and the supply widgets are powered up/down.

2020-10-05cpufreq: stats: Defer stats update to cpufreq_stats_record_transition()Viresh Kumar
In order to prepare for lock-less stats update, add support to defer any updates to it until cpufreq_stats_record_transition() is called. The stats were updated from two places earlier: - show_time_in_state(): This can be easily deferred, all we need is to calculate the delta duration again in this routine to show the current state's time-in-state. - store_reset(): This is a bit tricky as we need to clear the stats here and avoid races with simultaneous call to cpufreq_stats_record_transition(). Fix that by deferring the reset of the stats (within the code) to the next call to cpufreq_stats_record_transition(), but since we need to keep showing the right stats until that time, we capture the reset time and account for the time since last time reset was called until the time cpufreq_stats_record_transition() update the stats. User space will continue seeing the stats correctly, everything will be 0 after the stats are reset, apart from the time-in-state of the current state, until the time a frequency switch happens.

Pattern properties go under 'patternProperties', not 'properties'. Otherwise, the pattern is treated as a literal string.

2020-10-05net: dsa: propagate switchdev vlan_filtering prepare phase to driversVladimir Oltean
A driver may refuse to enable VLAN filtering for any reason beyond what the DSA framework cares about, such as: - having tc-flower rules that rely on the switch being VLAN-aware - the particular switch does not support VLAN, even if the driver does (the DSA framework just checks for the presence of the .port_vlan_add and .port_vlan_del pointers) - simply not supporting this configuration to be toggled at runtime Currently, when a driver rejects a configuration it cannot support, it does this from the commit phase, which triggers various warnings in switchdev. So propagate the prepare phase to drivers, to give them the ability to refuse invalid configurations cleanly and avoid the warnings. Since we need to modify all function prototypes and check for the prepare phase from within the drivers, take that opportunity and move the existing driver restrictions within the prepare phase where that is possible and easy.
