2019-11-06hwmon: Add support for ltc2947Nuno Sá
The ltc2947 is a high precision power and energy monitor with an internal sense resistor supporting up to +/- 30A. Three internal no Latency ADCs ensure accurate measurement of voltage and current, while high-bandwidth analog multiplication of voltage and current provides accurate power measurement in a wide range of applications. Internal or external clocking options enable precise charge and energy measurements.

2019-11-06hwmon: (ina3221) Add summation feature supportNicolin Chen
This patch implements the summation feature of INA3221, mainly the SCC (enabling) and SF (warning flag) bits of MASK_ENABLE register, INA3221_SHUNT_SUM (summation of shunt voltages) register, and the INA3221_CRIT_SUM (its critical alert setting) register. Although the summation feature allows user to select which channels to be added to the result, as an initial support, this patch simply selects all channels by default, with one only condition: all shunt resistor values need to be the same. This is because the summation of current channels can be only accurately calculated, using shunt voltage sum register, if all shunt resistors are equivalent.

2019-11-01net: fix installing orphaned programsJakub Kicinski
When netdevice with offloaded BPF programs is destroyed the programs are orphaned and removed from the program IDA - their IDs get released (the programs may remain accessible via existing open file descriptors and pinned files). After IDs are released they are set to 0. This confuses dev_change_xdp_fd() because it compares the __dev_xdp_query() result where 0 means no program with prog->aux->id where 0 means orphaned. dev_change_xdp_fd() would have incorrectly returned success even though it had not installed the program. Since drivers already catch this case via bpf_offload_dev_match() let them handle this case. The error message drivers produce in this case ("program loaded for a different device") is in fact correct as the orphaned program must had to be loaded for a different device.

2019-11-01inet: stop leaking jiffies on the wireEric Dumazet
Historically linux tried to stick to RFC 791, 1122, 2003 for IPv4 ID field generation. RFC 6864 made clear that no matter how hard we try, we can not ensure unicity of IP ID within maximum lifetime for all datagrams with a given source address/destination address/protocol tuple. Linux uses a per socket inet generator (inet_id), initialized at connection startup with a XOR of 'jiffies' and other fields that appear clear on the wire. Thiemo Nagel pointed that this strategy is a privacy concern as this provides 16 bits of entropy to fingerprint devices. Let's switch to a random starting point, this is just as good as far as RFC 6864 is concerned and does not leak anything critical.

Lyude Paul fixes an issue where a fatal read error occurs when the device is unplugged from the machine. So change the read error into a warn while the device is still present. Manfred Rudigier found that the i350 device was not apart of the "Media Auto Sense" feature, yet the device supports it. So add the missing i350 device to the check and fix an issue where the media auto sense would flip/flop when no cable was connected to the port causing spurious kernel log messages. I fixed an issue where the fix to resolve receive buffer starvation was applied in more than one place in the driver, one being the incorrect location in the i40e driver. Wenwen Wang fixes a potential memory leak in e1000 where allocated memory is not properly cleaned up in one of the error paths.

2019-11-01i40e: Fix receive buffer starvation for AF_XDPJeff Kirsher
Magnus's fix to resolve a potential receive buffer starvation for AF_XDP got applied to both the i40e_xsk_umem_enable/disable() functions, when it should have only been applied to the "enable". So clean up the undesired code in the disable function.

2019-11-01igb: Fix constant media auto sense switching when no cable is connectedManfred Rudigier
At least on the i350 there is an annoying behavior that is maybe also present on 82580 devices, but was probably not noticed yet as MAS is not widely used. If no cable is connected on both fiber/copper ports the media auto sense code will constantly swap between them as part of the watchdog task and produce many unnecessary kernel log messages. The swap code responsible for this behavior (switching to fiber) should not be executed if the current media type is copper and there is no signal detected on the fiber port. In this case we can safely wait until the AUTOSENSE_EN bit is cleared.

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 fixes from Will Deacon: "These are almost exclusively related to CPU errata in CPUs from Broadcom and Qualcomm where the workarounds were either not being enabled when they should have been or enabled when they shouldn't have been. The only "interesting" fix is ensuring that writeable, shared mappings are initially mapped as clean since we inadvertently broke the logic back in v4.14 and then noticed the problem via code inspection the other day. The only critical issue we have outstanding is a sporadic NULL dereference in the scheduler, which doesn't appear to be arm64-specific and PeterZ is tearing his hair out over it at the moment.
