2019-02-24Revert "bridge: do not add port to router list when receives query with ↵Hangbin Liu1-8/+1
source 0.0.0.0" This reverts commit 5a2de63fd1a5 ("bridge: do not add port to router list when receives query with source 0.0.0.0") and commit 0fe5119e267f ("net: bridge: remove ipv6 zero address check in mcast queries") The reason is RFC 4541 is not a standard but suggestive. Currently we will elect 0.0.0.0 as Querier if there is no ip address configured on bridge. If we do not add the port which recives query with source 0.0.0.0 to router list, the IGMP reports will not be about to forward to Querier, IGMP data will also not be able to forward to dest. As Nikolay suggested, revert this change first and add a boolopt api to disable none-zero election in future if needed.

2019-02-24selftests: fib_tests: sleep after changing carrier. again.Thadeu Lima de Souza Cascardo1-0/+1
Just like commit e2ba732a1681 ("selftests: fib_tests: sleep after changing carrier"), wait one second to allow linkwatch to propagate the carrier change to the stack. There are two sets of carrier tests. The first slept after the carrier was set to off, and when the second set ran, it was likely that the linkwatch would be able to run again without much delay, reducing the likelihood of a race. However, if you run 'fib_tests.sh -t carrier' on a loop, you will quickly notice the failures. Sleeping on the second set of tests make the failures go away.

Ido Schimmel says: ==================== mlxsw: Add support for new port types and speeds for Spectrum-2 Shalom says: This patchset adds support for new port types and speeds for Spectrum-2. Patch #1 + #2 removes an unsupported PTYS field and a duplicate link mode entry. Patch #3 queries port's connector type from firmware instead of deriving it from port admin state. Patch #4 renames functions which relate to port type-speed to be Spectrum-1 specific. Patch #5 defines port type-speed operations and applies it for Spectrum-1. Patch #6 + #7 are small renaming and cosmetic changes. Patch #8 adds new port type-speed fields for PTYS register. These new fields extend the existing ones in order to support more types and speeds. Patch #9 adds Spectrum-2 support for port type-speed operations. Patch #10 adds Spectrum-2 new port types and speeds. For Spectrum-2, the user must configure all the types per speed if he / she wants a specific speed to be advertised. For example, if the user wants to advertise 100Gbps 4-lanes speed, the following ethtool bits should be advertised: Supported ethtool bits for 100Gbps 4-lanes: 0x1000000000 100000baseKR4 Full 0x2000000000 100000baseSR4 Full 0x4000000000 100000baseCR4 Full 0x8000000000 100000baseLR4_ER4 Full Command for advertising 100Gbps 4-lanes: ethtool -s enp3s0np1 advertise 0xF000000000 ==================== Signed-off-by: David S.

While freeing interrupt handlers in error path, don't assume that all requested interrupts are per-processor interrupts and properly release standard interrupts too.

2019-02-23clocksource/drivers/exynos_mct: Remove dead codeMarek Szyprowski1-7/+2
Exynos Multi-Core Timer driver is used only on device-tree based systems, so remove non-dt related code. In case of !CONFIG_OF the code is anyway equal because of_irq_count() has a stub returning 0. Device node pointer is always provided when driver has been probed from device tree.

2019-02-23clocksource/drivers/riscv: Add required checks during clock source initAtish Patra1-3/+20
Currently, clocksource registration happens for an invalid cpu for non-smp kernels. This lead to kernel panic as cpu hotplug registration will fail for those cpus. Moreover, riscv_hartid_to_cpuid can return errors now. Do not proceed if hartid or cpuid is invalid. Take this opportunity to print appropriate error strings for different failure cases.

2019-02-23clocksource/drivers/exynos_mct: Clear timer interrupt when shutdownStuart Menefy1-0/+1
When shutting down the timer, ensure that after we have stopped the timer any pending interrupts are cleared. This fixes a problem when suspending, as interrupts are disabled before the timer is stopped, so the timer interrupt may still be asserted, preventing the system entering a low power state when the wfi is executed.
